The NRZI and HDLC are not inherent to the 9600 modem, as you note it is
just a FSK modem with fancy shaping. The NRZI and HDLC are artifacts of
the associated *packet* TNC and the protocol it is using. The 400 bps
satellite telemetry modem is different. It is not FSK, it is BPSK, and
it is not packetized but rather it operates on continuous data streams.
It depends for clock recovery on the transmitted signal being Manchester
encoded as I mentioned. This makes it differential or DBPSK, and so is
not polarity sensitive since it responds only to state changes in the
transmitted signal. Manchester coding is different from NRZI because
the data clock is directly embedded in the signal. This means, among
other things, that no data scrambler is required.

At least that's what my memory says. I built one of the things right
after Oscar 10 was launched, but have misplaced the magazine article
on which it is based.

I don't object, at least not too strongly, to this advice. However,
both of these units do give the digital modes a bad name in the
weak signal arena, because they use suboptimal techniques, and
frankly because they don't even implement the techniques they do
use in an optimum manner. As long as you understand you're embracing
a popular rather than optimum technology, and don't come away with
the wrong impression of what digital methods are capable of doing,
using these appliances is Ok.

What bothers me is that these suboptimal choices are being entrenched
on HF. This is a case of mediocre being the enemy of better. I'd really
hate to see us remain entrenched at this level for another decade. This
is similar to the curse of the PC, with its limitations grandfathered down
to even the latest units in order to remain backward compatible with 15 year
old technical decisions that, in hindsight, weren't very good.

We should be moving away from non-coherent FSK, and we should be moving
away from basic symbol rates of 300 baud for the HF channel. Those are
suboptimal choices for HF digital. Better alternatives need not be more
expensive, or complicated to operate, but if we are burdened by a large
installed base of inferior machinery, there's little incentive to buy,
build, or use better methods, IE we face an interoperability crisis.

Matt: we've recently been doing a lot of short-distance (<150 mile)
AMTOR/PacTOR/GTOR/Packet tests on 80m in New England using an automatic
test program we've written.  It measures link time and throughput in
chars/sec.  Would be more than glad to try some 80m and other-band
tests/ops with you.  Gimme a shout at [e-mail].  73  Ken.

AEA and their original DSP programmer had a parting of the ways after
the satellite modems were completed. (I won't get into that, having
only heard the programmer's side of that dispute.) Anyway, that stopped
DSP code development for the unit for some time. The rumor mill had it
that AEA had engaged the services of another DSP programmer, but as you
note, there doesn't seem to have been any further code released for use
with these units. At this point it is reasonable to question if there
ever will be more code released for this box.

AEA did release some documentation on this unit so that independent
programmers could work with it, but I haven't seen any code released
as a result of that (Grace's DSP-12 seems to share a similar fate).
TAPR seems to finally have their DSP card available for programmers to
use, but again code has been slow in coming, and it's priced higher
than many available alternatives.

Other DSP solutions intended for amateur use have also appeared,
including the HAL P-38 card and the PACTOR II unit from Germany
(also to be second sourced by PacComm). These units seem to have
committed development teams, and likely have a future.

In the meanwhile, DSP evaluation kits, and sound cards bearing DSP
processors, have become available which are much cheaper than any
of the above units (most available for under $100), and for which
cheap (or free) development tools and documentation have become
available. Among these are the TI kits, the Motorola kits, and the
Analog Devices kits. The latter chipset is also used on the inexpensive
Cardinal sound card, which also has an available software development
toolset. And there is an IBM sound card bearing the TMS320C25 DSP chip
as well.  The sound cards are particularly attractive because of their
tight coupling to the host PC, but most of the evaluation kits are
also suitable for use as external modems for ordinary TNCs.

So what's a buyer to do? I'd suggest that if you're happy with the
current code available for the AEA or Grace boxes, and if you can
stomach the price, you go ahead and buy one of them. However, if
you're expecting lots of enhancements down the road, you'd do better
looking at the platforms the code developers are embracing.

Becoming a code developer yourself is an option. In particular,
the TMS320 family and the ADSP-2100 family are well supported
with tools and example code. The Analog Devices unit in particular
has an available set of source code cookbooks that implement everything
up through a V32 modem on their EZkit development platform. It only
took me a couple of days from ground zero to get a functioning FSK
modem programmed on the EZkit, and I'm no DSP programming whiz, in
fact this was my first attempt at practical DSP programming. Because
of that, I'm sure the implementation is far from optimum, for example
I still haven't figured out a good way to communicate tuning indicator
data to the PC for display, but the darn thing does work, and pretty
well too, even with moderately weak signals. Really weak signals,
ones I can't detect by ear, will have to wait on my figuring out
the tuning indicator problem and shifting to a more robust encoding
than naked FSK. One of the cookbooks has a trellis coding demodulator
that ought to serve for really weak signal detection.

(Really weak signal performance probably isn't very important to
you since most HF signals are at least moderately strong, but it's
a current pet enthusiasm of mine.)

Yes, Kevin, you are just too much of a tech weenie, but without the years
to support the half vast claims you make.  Nothing is further from the
truth than old ham radio is defunct.  It is not and never will be since
you fail to recognize the difference between social aspects of the hobby
and the technical aspects that are possible.  Take a few more years of
observation before you tell the rest of us "old farts" where ham radio is!

Hope this helped you out.  I don't think you really need the NOHI at the

What's the scoop with this, is it legal to use 2m packet for remote

As a licensee, you can do whatever you want on 2m.  There are some
restrictions, but remote control isn't one of them.  If you mean radio
model control then no.  Common sense tells you that thousands of
talkies all looking at you controlling your model will key up to kill it :-)

I don't know if and where it is on the Internet.  I have a copy
of the 7plus 2.03 sources on my system, and they already include the
support for Linux and the Amiga.
Documentation is included in English and German.

You can get them from my system by calling [phone] between
23:00 and 07:30 local time (GMT+1), logging in to the BBS and getting
the file 7plus203.zip from the area "Utils-MSDOS".
You could also try some of the wellknown archive sites and look for
this filename (or 7plus203.lzh)

Can you recommend a good host or pms program ?  Ideally, I'd like
something that provides enough of a scripting facility for me to be able
to pull selected messages (bulletins) off of the local packet BBS, and
also be able to receive forwarded mail from the BBS.

I'm running a 8 Mhz AT (640K) and a KPC-3.  The KPC-3's pbbs is fine, but
too small for "serious" work in capturing bulletins.

I've tried: paKet 6.1, TSTHOST, PTM, Eskay Packet ("sp")Lan-Link, and while
all are good,
they all have limitations (not enough built in editor space, PMS problems
(loosing track of BIDS...etc.) to make them unacceptable.

Please let me know of any Internet sources for the software you recommend.

Thanks!

Joe

The MF10 chip was eliminated by the instructions in the TAPR TNC

Since paKet will send sequences like CTRL-Z to the TNC my guess is that
either the RS232 communication is not set correctly or that your command
mode string in the TNC has been changed. You can prove that the
RS 232 baud rate is correct by turning the TNC off/on after
paket is up and running and watch for the TNC copywrite message.

Hope this helps.

The Rochester Packet Scociety has assembled and tested about 250 Baycomm
modems.  I use them in portable operations all the time.  For the average
user they work great.  Things to know:

This is a DOS program.  It probably won't work under windows.

It works great on original XT and slow computers.

It must run on a IBM compatable computer.  Although with programs
designed for other computer you can use the same modem.  I have seen the
RAPS modem running on MACs using SoftKiss and Amigas using a program that
I forgot the name of.  Baycom was written for the IBM.

We give out the 1.4 version of BAYCOM.  Baycom is currently two versions
ahead of that.  To upgrade past 1.4 you must register the shareware.
PACCOMM is the US rep.

The RAPS modem uses the same modem as the PACCOMM TNCs.

$30 aligned and tested.  software and docs included, no cables.

The serial port must be IBM compatible.  Some lap-tops might not be able
to power the modem so separate power might be needed.

I'm willing to swap your fried TNC for a BAYComm setup.

I will need to know what the connector is on the comm-port you will use on
your computer (9 or 25 pin) and what radio you are using and the mike
pinout.

Thanks.

mirrorshades.ucsd.edu is a DNS server for AMPRnet to resolve names.
Some Amateur IP subnets have connections through ISP's to the Net, but
are usually limited to those subnets. Although all name resolves go
through UCSD as a primary. If an amateur IP subnet is connected to the
Net, then usually a route is sent to UCSD to denote the path.

Your point is absolutely correct, but the original question was not 'how do I
work around an awful radio' but 'what should I look for in a _good_ radio?'

Also, I think you mean 'High" BER circuits - a low BER circuit has very few bit
errors, and handles big packets fine.

BTW, some of the networking software writers are working on supporting 1k frame
sizes, so we should see something soon.  Full dux isn't the panacea for poor
TXDelay, though, because it needs a high utilization ratio to be considered
efficient, but I like it because it forces you to use dedicated point-to-point
links.  Most people don't realize it, but since X.25 (the basis for AX.25) is a
point-to-point protocol (not confused with internet PPP), as soon as you add a
third station on the channel, throughput drops like a stone.

Many links could be vastly improved in performance by just making it a link
between only 2 stations, no need to up the baud rate...

Would you agree, without having to go buy a copy of some paper, that the

That makes sense, but then the question becomes "what is considered a
model?".   Packet stations can be used to report telemetry from say a
weather station, but how about control of a experimental robotic platform?
I believe that was the question originally asked.   Since this is
"mobile";  not really a "model", but is used for remote control,  is this
legal for a ham?

  Monitor some packet freqs (mon on command) and watch for people

Well yes.  But I was drinking a fine bottle of Sam Adams, and a couple of my

Give that man a CIGAR!

Packet networking is like sharks to blood.  Some idiot puts up a netrom
node (or rose, or whatever), and 10 other people say "Me Too!"

If these node admins would change frequency every time some shmuck
put up another frequency cross-over, they could keep the through-put up.

9600 went the same way as 1200!  All are backboned on the same freq,
with omni antenna's - no point to point.  Cheap bastards...

I did a paper once on a 3 radio node stack.  1 for 2m (the user freq, omni),
and two 9600.  One for the route north, and another for the route south.
Using TEKK and beams I figured we could run from OSU to OU in five hops.
Do it TCP/IP on the backbone, and that and regular AX.25 on the 2m side.

Nope, no one interested.  They like crap, NO they actually love crap...

The simple model of one link pointing to the next link and running full-duplex
is what he means I'm sure.  The bit regenerator "full-duplex" while 100%
better than the current method of networking, is really only good for each
local LAN.  That is, the LAN users should hear everyone else, and that will
reduce collisions (DAMA does the same thing but is much slower, because
it is master, and everyone else is slave).  I don't know why they call that
full-duplex, because only one user can transmit at a time.

Take one of these and hook it to a Pt-Pt links to the next LAN, and that's
what I mean.  Full-duplex here, means that each end of the link can transmit
any time they want because they are the only two on the freq pair.

You mean the bunch of (mostly) old men meeting each week at the

That's NOT the hobby I started 17 years ago.

HF contact are now mostly "contest style" 5 seconds exchanges.

VHF repeater are CB-like nonsense.

Technically, the most difficult thing is to get the japanese made
tranceiver out of the box and reading the programming instruction
of the on-board computer.

That's today Ham-Radio ...

JNOS does not epitomize the concept of "user friendly" software. (I've

The granularity of time slices on a phone line do not lend themselves
well to TDMA networking :-)

Then we need to ban phone patches, too.

Seriously, the entire issue of BBS forwarding - both mail and bulletins -
could take a lesson from the Internet.

NNTP has a place here. What has turned most BBS operators (and users) off
is the need to switch to IP based networking. While I would like to see
that happen, most people don't want to be bothered. HOWEVER, there isn't
anything stopping us from using NNTP over AX.25 VC's. All NNTP wants to
see is a reliable sequenced link between end-points. In this
respect there is no difference between TCP and an AX.25 VC. What *is*
different is the addressing scheme used to identify nodes on the network.
And in this case, never the twain shall meet.

The same argument applies to mail traffic. SMTP doesn't care about the
underlying transport, as long as it provides a reliable end-to-end
sequenced data pipe. And again, the addressing simply does not jive
with the current BBS addressing scheme, thus the user community shuns
it because they would have to learn something new. This is a shame, as
there is some very good work coming out of the IETF right now that
addresses many of the problems we face (specifically addressing
unreliable connectivity, sites with limited resources, etc).

It can be made to work, though, if people agree to cooperate. Internet
domain based addressing works just fine over UUCP for both mail
and news. UUCP is a store-and-forward network just like the current BBS
network. Given a scheme for distributing the routing tables we could
merge the functionality of Internet domain addressing with the
AX.25 transport layer in a seamless manner, providing better connectivity
for all (and that's what ham radio is all about).

For this to work we need three things:

1) Cooperation from the BBS software authors to implement the new
   functionality (specifically SMTP, NNTP, and RFC822 based mailers).
   This has been done many times over, and much of the code is available
   and can be re-used for this application. (Check out your local land-
   line BBS for an example.)

2) A distributed network routing database (ala the UUCP maps).

3) A user community willing to accept change (a new addressing format).

I hereby step forward and volunteer to take on #2 above. Who else is
willing to contribute to moving the BBS mail/news environment forward?

   It could also be that he's (or she!) is running more power and you
aren't putting out enough to reach them. Just another idea. I sometimes
see stations when monitoring but when I try to connect it's no go. Too far
away for me and I'm not cranking out enough power. Try popoing up your
power if possible and see what happens.

The title of the thread does suggest we should keep that in mind.  Besides
being a waste of time, TxDelay is also a 'window' where packet collisions
can occur (one station has decided to transmit; other ones can't hear it).
 So regardless of the packet length, the transmit delay should be as close
to zero as feasible.  It really isn't related to packet length at all.

Another related timing issue is how much preamble the receiver must have
before it can successfully decode the packet.  This is TxDelay that must be
added in addition to that required by the sending radio.  It is generally a
modem/TNC performance measure, unless some idiot insists on using the RF
squelch in the radio.

The time for the radio to start receiving after it has stopped transmitting
is also important, but less so than the other two.  Adding some RESPTIME
(time after receiving a packet before responding to it) will compensate for
this with a little degradation in point-to-point links and probably not
much at all in a multi-user situation.  Adding TXDELAY instead of RESPTIME
in this situation should definitely not be done as will allow more
collisions and QRM the channel with useless Flags.  Many radios can be
modified to start receiving faster by disabling the circuit which turns off
power to the receiver IF and audio circuitry while transmitting.

There is no cure for long TxDelay.  The best bet is deterministic access
with the TxDelay of each station accounted for, but that seems excessively
complicated compared to building good radios in the first place.

I don't see how full-duplex requires point to point links, I suppose you
are talking about a bit regenerator rather than a full-duplex node.

There are several other things that should be considered, longer packets
being one idea along with:

* Forward error correction.  Could be backwards-compatible added by sending
UI frames with error check/correct bits immediately after a conventional
data frame.  Also the level of ECC transmitted could dynamically vary
depending on the number of errors actually experienced.  The need for FEC
will be even more acute if packet lengths are increased.

* Smart REJs.  As AX.25 works now, for example if a group of 4 packets are
sent at once and the first one is missed, the other 3 must be retransmitted
as well.  Sending one long packet instead of 4 short ones has a
slightly worse effect, if one error occurs in it the whole packet must be
re-transmitted.  Improving the REJ process so the correctly-received
packets further along in the sequence are acknowledged would be a very
worthwhile development.  Also this would make it practical to have a window
of more than 7 outstanding packets (even 7 is way too many now, unless the
link is absolutely perfect).  Then the amount of data per transmission
could be increased, by sending many short packets with an ability to retry
individually any that are missed.  This would be much better under moderate
to high error conditions than keeping the present retry protocol and using
long packets.

* Deterministic access (What ever happened to DAMA?)  For point to point
links even more drastic fixed time-slot type methods could be used, saving
the need to send 'polling' packets.  Either way, more than 2 stations
could work work without the increasing chance of collisions that occurs
with the present random access system.  This may be especially good for
half-duplex nodes, which are almost always a 3-station situation at least.

* Full duplex with remote DCD.  With a full-duplex node, there is the
possibility of communicating the instantaneous uplink DCD status to all the
users, thus reducing the probability of collisions from 'hidden stations'.
This could be done in a manner similar to the 'busy bits' used by the
digital control channels in cellular phones.  If FEC is implemented,
full-duplex nodes would 'scrub' errors out of packets before repeating
them.

Full-duplex bit regenerators should have some 'hang time' like voice
repeaters and transmit a continuous series of Aborts while the input is
idle (with modification to the end stations of course to consider this
condition 'no DCD').  In this way, all the end stations can maintain bit
synchronization, and know immediatly when the input is idle.  Additional
TxDelay resulting from the repeater is not needed.

* Split-rate installations.  Almost any radio can be modified with a simple
tap of the discriminator audio to receive 9600 baud, but few can transmit
it acceptably.  Therefore, some way for primarily one-way links like those
to  BBS and DX Cluster users to downlink at 9600, but uplink at 1200 may be
useful in the interim.  (It should probably be done on two different
frequencies, i.e. an optional 1200 uplink-only channel in addition to the
conventional 9600 channel.)  Presently, there seems to be no hardware on
the market which can operate in this manner.

In conclusion, it seems to me that there is a fascination with baud rates
because it is an easily quantifiable thing, fairly simple to implement, and
it "feels right" that increasing the baud rate means faster throughput.  Of
course it does, but that doesn't mean that the rest of the system is
anywhere near as efficient as it could be.  The present implementation of
AX.25 works marginally well with small quantities of data at 1200 baud, but
 is definitely showing its wire-line heritage by its incredibly poor
handling of errors and multiple access, conditions common in radio links.

I'm not sure I would agree with this.  There are plenty of
phase modulated crystal controlled radios out there (well,
a lot of land mobile radios) that have spiffy T/R times but
do not have the correct frequency response.  I think Don
was trying to say T/R time is not so much more important
than other characteristics that it is some kind of litmus
test all by itself.

You need a radio with a proper frequency response to operate
9600 baud at all; this radio also needs a fast T/R-R/T turn
around in order to be efficient.  One doesn't take priority
over the other.

I wouldn't advise it, even if you were to get your licence.  For stuff
like that you would be better 440 or above.  One might even consider
using some of the business band freq. but then again you have to pay
about $140.00 a year for that licence.

If my memory serve me correctly, for this type of use you would have
to be 220Mhz or above for that to be legal.  At least when it comes
the control of a repeater, the control freq. need to be on a freq that
is 220Mhz or above.

Not exactly.  Once the transmitter is up to power, and on frequency, the flags
sent during TXDelay are hearable to other stations, and cause DCD to light.
(But, before the TX is ready, yes, it is a hidden transmitter. On a practical
basis, this isn't a huge problem.  But the point, that any TXDelay is evil, is
well taken)

Actually, I wan't thinking of a bunch of half-duplex stations talking through a
duplex repeater, but tow full duplex stations talking to each other.  both
transmitters are always at full power, both receivers are always listening.  A
third station simply cannot fit in.

It is coming!  Keep your eyes open for info about FlexNet, very popular
networking software in Europe.  Read about it in the latest DCC proceedings.
It implements full master/slave DAMA !!

This isn't as easy as it sounds, but probably doable.  We are playing with a
similar split-rate idea: 1k2 (or up to 9k6) from user to server, and 56k from
server to user.  Such a wide split is hard, though.  Think of a WWW site:
mostly mouse clicks in, and tons of data out.  perfect for a split-rate
channel. (BTW, anyone interested in this, E-Mail me!)

The Euphoria Tape

Do The Euphoria Tape alone the first time, and then
with a lover. It's a phenomenon you will feel within
the first 3 minutes of use -- what you feel the rest of
the time is unbelievable.

The Euphoria Tape.

It was first whispered about on college campuses, and
only experimented with in seclusion, or among close
friends in private settings, but it has now become a
cult rush and is considered the next passion of our
Cyber lifestyles.

The Euphoria Tape.

Not a drug, not a chemical, but an audio stimulation of
brain centers controlling pleasure. And agony. And ecstacy.
The buzz. An audio mesmer signal strokes the base of the
mind, choking out pain sensations and producing the violent
flow of... euphoria.

The Euphoria Tape.

Copies have changed hands from friends to friends to other
friends. It is not regulated, there are no laws yet restricting
use of The Euphoria Tape.

The Euphoria Tape is rushing the masses.

Hello I am looking for a program to monitor a specific frequency (packet) and print out a screen or file that will give me all of the
important information of the channel usage.

I have FTP'ed MONMAX.ZIP from the TAPR WWW site but it seems that the program does not work. Certain things do work in
the package of about 5 sub-programs but the important ones that total the raw data and the one that converts it to a file that can
be read by a spreadsheet to create graphs do not.

This must be a PC based system (I know of a good one but for the MAC) and that is about it. I am trying to make a point in my
local area of what problems too many digi's and beacons can do to a frequency. Some locals are using UI Beacon frames
(APRS program) in a 3 or more hop path while others are placing digi's with the same ALIAS about 10 miles from each other with
the SAME coverage area. I just hate to see the frequency become like all the others where a packet can't make it thru and
where packet just becomes RACKET!  If I get some hard facts on the problem maybe some of the people will re-think their
position and go about differently on how they use the network.

Thanks for any help and please E-Mail any information or file ATTACHMENT to [e-mail]

I'd like to add another vote for the KPC-3, it has the smallest
footprint and has the GPS capabilities.
I used a Baycom TNC while my Kam was in the shop and the
Baycom unit is VERY VERY particular about the tones, I even
resorted to using a capacitor in line to change the audio with
limited success.

Has anyone succeeded in getting a QSL card from the CY9CWI
expedition to St. Paul Island back in August 1994? I've
sent 2 SAE's with a green stamp to VE2CWI over the past
year with no luck. I would sure like to get it for my RTTY
DXCC # 305. Thanks...John, NJ0M.

Any idea how they avoid legalities regarding encrypted messages? I am
thinking of compressed packets embeded in an AX.25 packet. Not unlike
YAPP transfer of a ZIP file. If anybody monitoring misses one packet
they won't be able to unZip it.

I'm aware of patents/copyrights but there are public domain methods.

Depends on the wording of your licence. The UK licence distinguishes
between encoding to facilitate transmission and encryption to prevent
others using it. Of course, there is a very fine line between the two
and abuse of the system would no doubt lead to its withdrawal.

Compression is used in probably most of the BBS forwarding nowadays. It's
also used on some systems for compressing TCP/IP frames and other
applications. There is no set standard compression that people use, but
typically you'll find LZH, LZV and LZW compression used for 'on the fly'
compression. You can also compress offline with any compression program
like gzip, pkzip, arc, etc...

No probably running compression. It's up the a receiving station to figure
out a way to receive it. If someone was to run a non-standard data rate
it doesn't make it illegal just because nobody can decode it without having
to go through a lot of trouble. The only concern is that someone is going
to use compression or some other means to obscure the meaning and keep
others from monitoring. If you can't decode someone and they refuse to tell
you how they are transmitting their data, then they are probably suspect
to possibly operating illegally. But if someone was to tell you "We're
using LZV compression on our packets.", then that's all you need to know
to write the code to receive the data.  There's nothing illegal about it
at all. (at least in the US.)

              Digital Coordinators Participate
         In National Frequency Coordinator Meeting

Packet/Digital frequency coordinators were present, if somewhat
on the edge of the spotlight, in St. Louis this weekend for a
historic meeting of frequency coordinators from across the
country, sponsored by the ARRL.

The main purpose of the meeting was to respond to a question
initiated by the FCC about the possibility of creating a "single
point of contact" (SPOC) between the FCC and the amateur
frequency-coordinating community.  The meeting was also attended
by Ralph Haller, Deputy Chief of the FCC's Wireless
Telecommunications Bureau, ARRL President Rod Stafford KB6ZV,
several League Directors and members of the Spectrum Management
Committee, and of course, frequency coordinators or officers
from coordination groups covering almost every state.

The nearly unanimous answer from the group was "yes,"  there
should be a single point of contact, if that's what's necessary
to improve the coordination system and give it stronger support
from the FCC. The coordinators also decided to ask the ARRL to
provide services as the SPOC, although that decision was not
unanimous, and was bitterly opposed by the coordinator from
Indiana.  A five-member committee was chosen to draft the SPOC
structure to propose to the ARRL Board of Directors.

Although that was the only conclusive decision reached, the
assembled coordinators were generally, perhaps overwhelmingly,
in favor of more specific recognition by the FCC, something
Ralph Haller said the FCC was inclined to do.  The subject of
mandatory coordination for repeaters was discussed only briefly,
but it also received many favorable comments.  Debate on these
issued was deliberately avoided so that the main topic, creation
of a SPOC, could be completed in the short time available.

Digital coordinators attended the meeting from several states:
North Carolina, Missouri, Illinois, Kentucky, Kansas and
Oklahoma.  The question of the digital coordinator's place in
the coordination arena had originally been part of the agenda,
but was dropped along with many other topics as meeting
organizers realized that there would not be time for them all.
The chairman offered a separate meeting space for the digital
contingent if they wished, but all decided they felt their
presence was important in the main meeting, and in any group
effort by coordinators.

We did meet informally over dinner later, and discovered that
there were some common experiences among the states represented.
One is that digital coordination is a fairly new concept, and
it is not universally recognized as necessary among digital
spectrum users.   Also, in most states, digital coordination is
less formal than voice repeater coordination -- more of an
advice and record-keeping service than specific coordination
granting.  In several of the states, early digital pioneers
approached existing voice repeater coordination bodies and were
turned away... or vice-versa.

Today, as the need for digital coordination becomes clearer, and
as the need to include digital interests in spectrum management
becomes more evident, cooperation between voice and digital
coordinators is growing.

But there are still unanswered questions on how digital
coordinators will fit into a new arrangement with the FCC.  Will
digital coordinators be officially recognized by the FCC, as
voice repeater coordinators may be?  Could, and should,
coordination be mandatory for simplex digital systems, as is
being discussed for voice repeaters?

The digital coordinators also decided that now is the time to
begin a national dialog among themselves, probably via a digital
coordinator's mailing list on the internet.

I'd like to invite anyone involved in digital coordination, or
regional or statewide digital groups, to contact me about
participating is such a list.

Hi. I am Roby, sysop of F6BYH ( my own call ) operating Winlink v1.2.

I am interested too for bbs in south Europe. Could you re-forwards
what you will get ?
What should be the format of internet files. Winlink, for ex. , has a
special routine for import/export via electronic mails.
Best 73. Roby.

The << >> characters indicate the packet types and are used for the
ax.25 protocol to keep track of connections. They really have no
significance to the end user, but they are very important for the tnc.
As far as recieving "strange" packets, I would suggest that maybe you
are recieving some netrom nodes that use an extra protocol that is
controlled by software running on their computers. You can tell most
likely if that is the case by receiving large packets that "seem" to
contain raw ascii garbage. I am just suggesting that because of the
numbers (also known as the SSID) after the call are above one, which
might indicate a bbs or node that may use a different protocol which
requires extra software to decode. Also, if they are network nodes,
they may be set up to only accept connects from other network nodes.
By the way, you would only receive the information packets if you set
the PID command in the tnc to ON. Otherwise, you would just see lots
of <<rr>> packets.

If you format the data into serial ASCII, then it can be fed into a TNC at
the sending end, and received with another TNC at the receiving end.
Many microcontrollers, e.g. the MC68HC11 or PIC16C71, contain both
multiple-channel A/D converters and a CPU suitable for formatting the
data just about any way you want.  An advanced use of the microcontroller
would be to format the data into HDLC UI packets per AX.25, eliminating the
need for a TNC on the sending end.  Kantronics used to make a box which had
several A/D converters and an interface to a TNC, this is the 'no
construction' method.

If you can afford to lose some samples, a one-way transmission using UI
packets would do.  In that case, the samples should be time-stamped.  Using
the connected mode ensures that all the samples will arrive (though data
could overflow if the radio channel goes bad).  An additional drawback of
connected mode is that transceivers are needed at both ends rather than a
one-way radio link.

TAPR makes what you need. It's a small single chip micro that does
A/D (on several channels) and formats the information for packet
transmission. All you need to do is plug the box into the serial
port of a TNC. When you do a connect to the TNC, you command the
data to be downloaded to you. It's original purpose was for remote
weather telemetry, hence it's name, Metcom, but it also works fine
for any general telemetry purpose where you have an analog signal
that needs to be digitized and sent over a packet channel.

It isn't the baud rate that kills HF packet, it's the packet
crashes, and the unwillingness of operators to avoid them
by QSY-ing away from the stacks.

HF packet, as presently done, is incredibly lame. I'd suggest you use
the AMTOR and RTTY capabilities of your PK232 for your live QSOs. For
mail and file forwarding, present day HF packet practice is just barely
acceptable, but for live contacts it's practically worthless.

It's well past time we abandoned our present way of doing HF packet
and adopt better ways of handling shared channel forwarding. AX.25
and its attempts at CSMA are insufficient at HF, and the Bell 103
standard modems are an abomination on the HF channel. The technology
exists to do much better HF modems using much stronger codings. And
we need protocols that are receiving station driven. A receiving
station can ask for a timeslice for its transmitting partner on
demand, and that can practically eliminate the hidden terminal problem
so endemic at HF if implemented correctly. (Since, by definition,
terminals hidden from the transmitting station are visible to the
receiving station, and since receiving and transmitting stations
alternate, each can alert the other's potential hidden terminals
to an impending transmission. Done right, this can allow all the
stations on the channel to negotiate a near optimum channel utilization
strategy.)

SKip the HF packet, it's useless... Try getting started vhf, or uhf
with tcpip. Setup a cheep NOS box as a router/tnc interface then use
windoze or unix to access mail, ftp, nntp, etc. YOU might consider
setting up a server for <gasp!> www on packet. Hay what the heck, ham
radio packet is only about 10 years behind, start trying to catch it
up in your corner of the world!

Actually, it's both. The hidden terminal induced collisions are
a major problem, but so is too high a baud for the HF skywave
channel. Due to the multipath symbol distortion on HF skywave
signals, baud above 50 will suffer a very poor BER. Now the
baud of a signal and the bits per second of a signal *don't*
have to be the same. So you could still have a fairly respectable
bps while running at a sufficiently low baud. Clover does this
for example, using a basic baud of 31.25 but using symbol overloading
to support bps as high as 750. The common Bell 103 single bit per baud
signalling used presently for HF packet simply suffers too high a BER
under skywave multipath at 300 baud. It would have a much better BER
if operated at 50 baud, but because it uses no symbol overloading
that would also equate to 50 bps, and that's pretty poor throughput.
(FEC can help, but requires a good bit of overhead, and can be
overtaxed rather rapidly on a HF circuit being attempted at too high
a basic baud.)

If we want to reduce collisions, we need a different protocol,
or as you note we can QSY as long as a clear spot in the spectrum
is available. This negates much of the advantage of packet operation
however, since it is precisely because it allows spectrum timesharing
which makes it a better tool than things like AMTOR or Clover for
dealing with limited spectrum resources. If you can find a non-contending
channel, there are several methods better than packet for dealing with
the HF skywave channel, such as the above mentioned Clover.

Better encodings and modem designs help *all* digital modes, however,
by lowering the BER and reducing the need for retry requests. Just
increasing transmitter power is not a good solution for several reasons.
The first is that increased transmit power often makes the multipath
problem *worse* by raising the received level of more, and previously
weaker, multipath signals. And of course, higher power has the potential
to disrupt *other* communications near the channel.

We need desparately to adopt a more robust encoding than Bell 103
for the HF channel. And to keep throughput up, we need to go to
symbol overloading methods. And to make packet viable on HF, we
need better channel management protocols than AX.25. All of this
is available, in bits and pieces, already. All we need to do is
synthesize those bits and  pieces into a coherent new packet
system for HF use.

Sounds simple, right? Well in principle it is, but the devil is in
the details, and getting operators to *changeover* to a different
method than what has become entrenched is difficult too. The latter
is why I keep harping on all this. If operators are *educated* to
the deficiencies of current technique, perhaps they will be motivated
to clamor for better methods.

      First I want to say I am sorry that this has nothing
to do with the topic of this group. You may see this
message in other newsgroups, the reason is I am subscribed
to those too so please don't flame me. I have been posting
and reading to this group for a while. I just wanted to
let you people out know there is a way to get Cable TV for
FREE. I recieve this letter in the mail from a friend
that had told me it works. I gave this to one of my friends
and he had free cable in his house within 20 mins. I have not
tried this method yet but may soon try if my cable goes up in
price. If anyone would like a copy send the following to the
address below.

Address Envelope to:

FreeStuff
9393 N. 90th St.

Scottsdale, AZ  85258

Enclose in the envelope:

Send...

    $1.00 U.S MONEY    *** NO COINS *** NO CHECKS ***
 inside a sheet of carbon paper or construction paper,
 and send a *self-addressed*,*stamped* envelope to the

Thanxs,
Just think if you pay 30$ + a month. 1$ will save
you 359 + dollars a year.

I use a Kantronics KPC-3.  Its inexpensive (around $125, last time I
checked), tiny, runs off of internal power (internal 9 volt battery, you
solder in the battery terminal) or externally (12 volts).  Will handle
AX25 or TCP/IP protocols.  Will pass data at up to 1200 bps.

Hope this helps.

Hardware- standard modem cables work fine.

Software- Kantronics has a version of their software for the Mac as
well.  You can also use standard comm programs, such as zterm.

For most VHF stuff, I use zterm, and use the Kantronics HostMaster Mac
for HF work.

Not to intrude on Roger's business, which is a fine one, but you can
order the radio link he mentions directly from the manufacturer,
Comrad, for less.  Number is: 317-290-9107.  I've been using the
Comrad for a few years, they're reliable and mostly hassle-free.

You're right that this isn't the same as the intent of the provision
for RC model control in the regulations (which is an authorized *one-way*
transmission). What we have here is telemetry and telecommand. Both are
permitted in the amateur service. For example, when you access a 2 meter
phone patch with TT commands, you are doing telecommand operation, and
when call status signals are relayed back to you, the repeater is transmitting
telemetry. These are perfectly Ok according to the rules.

Now there's a slight catch, if you are controlling a remote transmitter,
you're in auxillary operation, and have to operate above 222 MHz. So
while the remote transmitter in the robotic vehicle can transmit telemetry
on 2 meters, and you can transmit telecommands to the robot on 2 meters,
you *can't* control the robot's *transmitter* via signals on 2 meters,
because that's auxillary operation and has to occur above 222 MHz. So
you'd need a separate transmitter-receiver pair operating above 222 MHa
to maintain control of the robot's transmitter if you want to be legal.

There are a couple of exceptions. Repeaters can operate under automatic
control (until third party communications commences anyway) and packet
network stations can operate under automatic control. So if you're using
a packet link, you don't need the auxillary control link (though you do
need a safety timeout timer as in all automatic control situations).

ah, HERE is the rub, isn't it.... Old dogs, new tricks...
Not likely. I've had an nntp server setup on packet for over 6mos. SO
far there are two users. (and one of them has written his own news
reader and modified the MFnos client for posting !) 90% of the hams
around here seem extrememly reluctant to actually learning anything
new. Once you have an appliance (hardware or software) available
you'll get a few 'adventureous' types, but other than that... phet....

>>It seems to me that forwarding over internet - or other

>>or governmental network has nothing to do with amateur radio.

I think the above statement is like saying what do phone lines have to do
with computers.The world is changing. The technologies are becoming
integrted. Ham radio can adapt to the change or wither and die.

Perhaps one of the strongest reasons to link digital amateur radio to the
internet is as a means of conveying information in the event of an
emergency.

Recently there were devastating hurricanes in the Caribbean. News from St.
Martin was first broadcast by marine single sideband. From there it was
relayed by pactor to a Florida station which was able to put it on the net.
The whole idea was to make the news available to friends and family of those
who were in the disaster area. Had the information not been put onto the
internet it might have floated around in ham circles and not been properly
distributed to people who needed the info. Ham radio played an important
role. So did the Net. Neither could have worked without the other.


I spend half of every year as a aboard a boat. My hf packet rig is my
primary tool for communicating with people who are important to me. Many of
my friends are hams, but as I am sure is the case with the majority of us,
most are not. Packet/internet gateways provide me with a means of
communicating with non-ham friends.

Ham radio, after all, is a hobby. We have many creative and inovative people
involved. I am greatful to the pioneers involved with linking packet to the
net.

I use an older version(2.1?) of crosstalk.  I redifined the keys so that,
for instance, shift F1 puts your MFJ1278 into HB 45,shift F2=HB 50 etc.
Most comercial com programs allow you to define the function key so you
can have up to 40 (f1,shft f1, alt f1, cntrl f1)....
I also wrote a basic program and compilled it with quickbasic(v4.5?).
I like it better than crosstalk, but (and I am not freaking out here) it
will not run on any thing higher than a 80286.  It will not run on any
386/sx/dx or 486/sx/dx.  It ran fine on my ps1(I must have had the only
ps1 with a serial card instead of the internal modem :)  I only use my
MFJ1278 for RTTY,AMTOR/ASCII(and when I am really into pain)/cw.  Of
course the only ASCII I have ever seen was W1aw(at least it works) I
use JVFAX for FAX and have received SSTV.  Don't bother trying to
receive any image modes with the MFJ1278(the timing skew is a nightmare
and you might want to front mount the cpu clock trim cap (grin).  JVfax
just blows the MFJ1278 out of the water.  Even with the simple opamp
"converter" for jvfax you get grey scale reception.  I have just
downloaded WXMAN 2.0 for the oakland ftp site.
Anyway, if want drop me an email and I will try to post/send my little
basic program to control the mfj(it is compilled for com1..I never
figured out how to use com3 or com 4).  It only supports reception, I
never got around to completing the transmite section.  Or you might
just try your hand at writting you own terminal program.

About NSCC:
1) It's a board based on Z8530 and compatible (how much?) with other board like
   this (OptoPcScc, PI2 (?))

2) Software that can be used, and that I know, are: TFPCX, NOS/NET, Linux

3) All about this board will be PUBBLIC DOMAIN, in the ham spirit

4) I'll NOT provvide any part of the board, only all paper necessary

5) I havn't used PLDs so everyone could build the board (the reduction in number
   of ICs will result only in 1 or 2 pieces)

6) Next version, I hope, will use DMA

        If you are sure about the COM PORTS.  Try turning the TNC off
after starting Paket.  Then turn the TNC back on.  Check and see
if the letters RT are displayed on the screen.  These will be bracketed
with a "happy face" and vertical double arrow.  If this is the case the
TNC is in HOST MODE,  try the

Press CTRL-A followed by OHON (all caps) and end with CTRL-W.  This

Steve, go to the dump and grab a couple of oven racks. Join them at
a 90 degree angle (wiring them together will do), and mount a dipole
along the axis of that join, spaced out about a 1/4-wave with a stick.
Viola, you have a corner reflector almost as good as one you could buy
at Radio Shack for $7. It will have good forward gain, and a *great*
front to back ratio. Just what you need for a pt-to-pt link. (You could
also use chicken wire over a wooden dowel frame if you don't want to
scrounge in the dump. Or you could just buy one from Rat Shack and
replace the driven element.)

You *could* use a yagi, but the corner reflector fits a window
well, and should serve your purpose with a minimum of tinkering.

a much better place to start would be:
        http://hydra.carleton.ca/info/pi2b.html

this is the actual PI2 information, there should be some info on ordering it there
as well.  There is also an email address which I think is [e-mail]
but I'm not sure about that.

The Azden is the only frequency-agile one, though.  Most commercial mobiles
belong here too, with a possible (fairly simple) mod to ditch the phase
modulator and FM the transmitter crystal directly.

Has anyone published the T/R times of these radios?  I was under the
impression they were hacked single-oscillator PLL jobs, which would have
poor T/R unless extroadinary measures were taken.  They seem to belong in
group 4.  I have not seen the major brands quantify T/R or response other
than the vague claim of '9600 Ready', which they are not.

Don is wrong here.  Any radio with reed relays (or no relays) and
fixed-frequency crystal oscillators has the basic hardware to get <30 ms
T/R easily (maybe speed up an R-C constant here and there, maintain
constant DC power to the receiver, etc.).  But getting good performance in
the ham bands may be difficult, especially if they are built for a far-away
'split' of the commercial band (such as 470-512 MHz).  Always determine
that before buying.  I would recommend surplus commercial rigs for
fixed-frequency installations where size isn't a problem, as they are much
less expensive than the Kantronics or TEKK as well as having better
front-ends and more TX power.

Which have been re-fitted with 'Data' jacks and re-marketed as '9600
ready'.  In other words, the current crop.

(1) Surplus commercial mobile (should have considered that in the first
place).  (2) 'Da Brick' (ordinary HT amplifier).  Modify the amplifier so
the PTT signal from the TNC gives it 'early warning' (i.e PTT from TNC
closes relays in the amp immediately, rather than waiting for RF from
radio), and the system T/R time shouldn't be degraded.

I do not know if this is common knowledge or not but I found a way to
use the FL-53A filter when in the rtty mode. I installed a signal diode
with the positive end to the RTTY line at D42 and the negative end to
the FCS line at D39. This enables the CW 250Hz filter switch to operate
in the cW and RTTY modes. Anybody have a similar mod?

Speak for yourself...!
Some of us are quite actively building and enjoying our own radios.

One guy who works at another of my company's plants is scratch-building a high
performance 6 meter station. A couple of the folks at my plant are into
microwaves, and have built some of the 10 GHz transverter kits that are out
there.

Me, I'm nearing completion of a scratch-built superhet 40m receiver, and am
about to start on the companion transmitter. I'm later going to build a
wide-band linear to boost any HF signal up to 25 watts minimum, for when I want
QRO! I'm also considering converters to add other bands to my receiver.

BTW, I've never had a 5-second contest-style exchange on HF. I (and my wife,
she's a ham, too) did work Field Day on 2 meter SSB.

Hi all,
I've received a number of enquiries recently about which is the latest
version of UltraPak, and what features etc. are supported, so here goes.....

The latest version of UltraPak is a beta release of 3.0, which is available
as the file upak30b.zip from the ftp site ftp.demon.co.uk in the directory
/pub/ham.  It is unlikely that there will be a full release of 3.0 now, as
version 4.0 is only a few weeks away from release.

Supported features in 3.0
=========================

Windows 3.1 or later required, Windows 95 OK
Any TNC supported, except Baycom modems.  UltraPak is a terminal mode
TNC driver.
Full multi-connect support.  Up to ten Receive Windows definable.
Logging of received data to disc.
Autolog feature - logging started only when a connection occurs.
All connections logged to disc if required.  Location of log file user
definable.
Receive Window splittable, so that two connections can be displayed at
once.
Autosplit facility - Receive Window splits when more than one connection occurs.
ASCII and YAPP binary file transfers - enhanced YAPP with crash recovery
from version 4.0 onwards.
Colours and fonts definable.
Full on-line Help, including TNC command reference.
Button access to all main features as well as normal menu access.
Text search facility in Receive Window.
TNC initialisation and reset automatically on entry/exit to/from the
software if required.
Script language.
"Easy connect" list - connect to a station with a single button click.
Point and click method of reading messages from a BBS listing on screen.
User-definable signature file to be added to all outgoing messages.
Message preparation utility, with file save and import facilities.
Full built-in PBBS (Personal Bulletin Board System) with auto-forward using
standard RLI/MBL protocol.
Forwarding can be set up on a time schedule or on exit from the PBBS or
entirely manually.

And there's a lot more besides!

UltraPak is a shareware product.  The distributed, unregistered version is
FULLY functional in ALL respects, but has a session limit of thirty minutes.
You may restart the software for subsequent sessions as many times as you like.
Registration costs 20 pounds sterling, and removes the session limit.
However, from version 4.0 onwards, the session limit on the unregistered
version is removed, as the facilities which will be available on that
version make it impossible to test out properly if the session is limited.
The upgrade to version 4.0 is of course free to those who registered for an
earlier version.

Try version 3.0 now.  And watch this space for news of 4.0!

73, Tim.

yep... Works great (well, it works as well as we've all come to expect MS
products to work)

I use ethernet cards to hook my windoze95 box to a cheep and dirty 286 box.
The 286 runs a stripped down version of NOS that is really just a router.
With the use of 'arp publish' my 286 will answer any arp requests for the
windoze box. With old 286 boxes costing about the same as a tnc or less this
is a simple inexpensive setup.

Use the -i parameter with ping.  It allows you to set the rate at which ping
sends packets.  ping -i 5 <hostname> seems to work pretty well.

Joe a radical?  Come on, Steve!

Commenting out the OI entry in sendmail.cf will force the /etc/hosts file to be
searched, but only if the DNS cannot be reached (some of the hosts I contact
have obsolete entries, which has caused me a few missent messages.  If I was
usnig my Linux box for radio only, I would try running named as an ampr.org
dns, however.

There is an application called LBBS.  Also, a PMS is included in
ax25-utils-1.3.30, but I haven't been able to make it work correctly.

Linux Version Mania

> (some of the 1.3.x kernels certainly aren't!)

My own interest in getting a version 3 kernel resulted in a big waste of time.
I got an earlier version (maybe 29, I forget) and it was a huge download.
After that, the linux group came alive with reports that everything was broken.
The NFS didn't work, etc.  Well, I can tell you, I certainly didn't think folks
could break so much stuff.  The version 3 stuff is scary now, because the
people involved are not the same breed as in the beginning.  They test about
10 minutes and call it functional...

Glad to hear that 3.30 is doing OK.  I think I'll wait for 4.25 or so before
I download all that poop again.

Pinging below Mach 1

> Use the -i parameter with ping.  It allows you to set the rate at which ping

Well I have to admit I never used that option.  Most of the time I just ping
to get the route set up, and then send the mail.  (although I don't really do
this much anymore, because I really don't think setting up the route first is
worth my time).  But, I agree, the ping -i is probably much better advice
than I gave.

Sendmail Not Reading /etc/hosts

Here again I admit to missing this option in the file.  I knew there was some
way to do it, but I must have really wanted to tackle the DNS pretty bad :-)
Actually I like the DNS, and I probably would consider my /etc/hosts an old
fashioned way to go.

Regarding JNOS BBS

No thanks.  I'd probably spend more time on my INN.  I've almost got it
working, but I think one of my shared libraries isn't right.

It sounds like you're missing a critical bit of information about Linux
kernel releases.  In general, even numbered dot releases (like 1.2) are
considered "stable" production releases, while the odd numbered ones (like
1.3) are considered "experimental" or "developer" releases.  Version 1.2 is
the current production platform, and is recommended for those who find the
rollercoaster ride of 1.3 releases a bit too bumpy for our taste.  Although
the developers are admittedly focusing the majority of their attention on
version 1.3, new 1.2 releases continue to hit the street.  Last June, for
example, I built a 1.2.9 kernel; when I needed to add ethernet support to
my kernel about a month ago, I grabbed a copy of most recent release, which
at the time was 1.2.13.  I haven't the foggiest notion what the current
release is today, and until I have a good reason to build another new kernel,
I really couldn't care less.  Keeping current for the sake of keeping current
is futile unless you have nothing better to do with your time than rebuild
your kernel once or twice a month.

Remember that there are a large number of people working independently of one
another on various components Linux, so it's to be expected that stuff will
break from release to release of the development kernel as major code changes
from different authors are integrated for the first time.  When the developers
have achieved their present objectives and integrated everything into a
reasonably stable platform, the result will be dubbed version 1.4.0 and
released to anal retentives like me who are hung up with reliability.  At the
same time, the developers will begin breaking everything all over again with
version 1.5.0.  Look at it this way: if you want to run the latest, buggy,
pre-release of Solaris, you have to pay Sun a couple grand for an SDK; on
Linux, the bugs are yours for the asking.  ;-)

Admittedly, in the case of the AX.25 kernel enhancements, it's tempting to
move to 1.3 since they're built into the kernel rather than patches to it.
Still, I've found release 29 of the AX.25 extensions runs quite happily on
1.2.x, and I'll probably stick with it until 1.4 makes the scene.  Last I
heard, this was tentatively targetted for the first of the year -- but then
that was last March....

Some time ago I bought their kit.  I found that the receiver suffered from
many spurious responses which, given right (wrong?) packet frequency would
make it pretty useless.  I did get it to receive 9600 but had a pretty
strong signal to work with and didn't make any performance measurements so
I can't really comment on the receive performance.  The transmitter was a
disaster!  Because they have no shielding anywhere in the radio the
transmitter output got back into the PLL and the resultant signal resembled
broadband noise.  I wasted a lot of time trying to clean that up and never
was successful.  I believe that  taking the time to build a good shield
around the PLL would have solved the problem but there are problems with
the board layout that make it a  difficult thing to do.  I did find a few
minor design errors which resulted a very long (for 9600 packet) TR
turnaround time.  They directly modulate the VCO, like most radios, so the
transmitter will distort the signal.  I never got far enough to worry about
that.

A friend of mine bought one and had similar problems.  Both of us wasted a
good bit of money.  Since then we have discovered the joys of converting
commercial (e.g., Motorola and GE) radios...they work!

My recommendation is to avoid the unit unless they have made major design
changes since the original radio (the 2-m version failed the transmitter
spurious output test -- see the QST review from about a year ago).

I am using the ax25 driver in combination with WNOS. It runs ok on a 486 PC, but not
well on a 286 PC. Replacing the ax25 prg and the Baycom modem by a tnc in
KISS mode solves the problem.
However I have been told that some people use the combination Baycom modem +
ax25 + WNOS succesfully on a 286 PC. I think there must exist different versions
of the ax25 driver. Can anyone inform me about this and let me know from where I
can FTP it....?

It is a PAL colorburst crystal.  Easy to get in Europe, I don't know
how common it is in the USA...

It's a standard PAL European (except France) TV colour-burst crystal and
they might be a bit difficult to get over there. I've got a couple lying

: Digi-Key corp shows several 4.43361 MHz xtals in their catalog. They can be
: reached at 1-800-344-4539. For orders there is a $5.00 handling charge. I
: have had good service from them. At least give them a call and get a catalog.

I think the 4.42261 Mhz is a common value, I got one without problems from a
local store and it was cheap too.

About TCM3105.zip, there are some flaws in the schematic. These are:

1) D2 shouldn't have been connected to CTS, it should have been in the TXD line!
2) There are two R3 resistors and R2 is missing. The resistor on the CTS line
should be R2.
3) Due toe R14 I didn't get any sound of the modem, but that may be due to
my trancseiver.

Jason,
I have a tigertronice (Baycom) modem for sale it works great and i just
dont have any use for it anymore. It is constructed in a 25 pin DB25
connector housing, has worked great with my gateway colorbook laptop. It
is in mint condition. $40. plus $3. for UPS. let me know via e-mail if you
are intrested.

I see a lot of posts about building 'the' Baycom modem.
harumph.
I have schematics for at least three different Baycom modems.
They use the TCM3105, mostly, but the circuits are a lot different.
I had, but cannot now find, a Baycom modem schematic using the
7910 modem IC.  Since the modem for the C-64 is about the same,
it would not be hard to create that one.
One commercial Baycom modem I have used is the one from Tigertronics.
It was not critical to tones, it was critical to audio level.
It just worked perfectly on three different radios with no changes.
It is just that the software (I bought version 1.6) was really
awful.  The Commodore 64 software (Digicom whatever version) is so
much more sophisticated.  You can run the C=64 system as a small
BBS.  Try doing that with Baycom.

Use your NDIS<->packet driver shim.

FTP to ftp.intel.com (I think) and grab the packet driver version of

Have you actually tested this? (sorry to ask).

The bpq ethernet module communicates directly with LSL, it doesn't use
IPX at all. Does pdipx provide the LSL connectivity?

You only need:-

LSL
ethernet driver
ODIDRV xxx
BPQCODE
and so on.

LSL acts as a packet switch to the ethernet driver (ie as a standard
interface, very similar in concept to bpq itself w.r.t. to its
interfaces). The ODIDRV program is multicasting the level-2 packets on
the ethernet. The format of the packets are:-

short                   length_of_data_in_this_ethernet_packet
char [5]                internal_bpq_data_and_some_useful_flags
char [14-400 odd]       the_level_2_frame

The length is there because the size of the ethernet frame won't
necessarily (and if it is less than 60 bytes, it won't) be the same
length as the level-2 frame + 5 bytes. It is in little-endian format.

The format of the 5 chars of bpq internal data is as per the raw read in
the host.doc file.

To use NDIS efficiently would require someone to interface to NDIS in
much the same way as ODIDRV currently interfaces to LSL. In principle it
isn't very difficult. I have Linux routines for doing this, which are
useful only to connect user mode tnc emulators (ie it doesn't provide
kernel level ax25 connectivity - someone else has done this in the
latest kernels I believe).

Hello,

I was just wondering is this possible? I have a collins S series station
is it possible to set it up to run Packet? I know there is a keying issue
but asside from that it sounds like it should work, at least theoretically?

Any help on the subject is greatly appreciated.

Good topic. Compression techniques can be valuable for conserving
channel time and capacity. We're allowed to use such techniques
when their intent is to facilitate transmission, not to obscure
meaning. That means we need to either use well known methods,
or keep records of the methods used so that enforcement authorities
can check on what we've sent if they suspect illegal activity.

Times are tough for those attempting to monitor, unconnected,
the transmissions of stations operated in connected modes.
Compression can make this more difficult. But it's not our
purpose to make the job of the eavesdropper easy. It's our
purpose to move our data in the most efficient possible manner,
and compression can be an assist to that.

Dictionary compression on block data, such as the common zip
methods, can be highly efficient, but aren't really well suited
to on-the-fly stream compression of short interactive messages.
Simple minded techniques like run length encoding can work on-
the-fly, and offer a modest compression advantage, while still
allowing the eavesdropper to resynchronize after a missed frame.
A standard dictonary also has merit for this application.

I'd suggest we need to look at two different compression needs.
For bulk data, sent as a large block, the methods we use on
our hard disks for compression are suitable, IE just send zip
files. For interactive use, we need a stream compression method
which cannot a priori analyze the complete block to build a
compression dictionary. I mentioned simple minded run length
coding, but modern telephone modems use more advanced stream
compression methods based on dynamic dictionaries that are much
better. Ideally, any message can be expressed as a single Godel
number. That would be the ultimate in compression. I don't think
we have the computing horsepower to do that yet, however.

Watch out for software patents.  Not a problem when doing your own
experiments, but they could be troublesome when implementing something
in a commercial box, or when putting software up for general distribution.

Most compression algorithms are covered by patents.

yes, a fixed table or some well-defined sync points would be better.

note that some systems already use compression, but use proprietary
methods (all different).
e.g. F6FBB mail forwarding, xNOS compression on TCP sockets.

Actually, the *good ones" are covered by patents but there are plenty of
alternatives available too that aren't quite so good and aren't patented
either.

AX25 was invented in a world that is now surprisingly distant. AX25 packet was
designed for dumb terminal access. In the past few years, that is pretty much a
thing of the past. Everyone uses some kind of PC (generically including Mac,
Amiga, Unix). In such a situation, many kinds of compression - even simple word
substitution, would be effective for AX25 BBS work.

In a related vein, our process of point to point links of AX25 packet at slow
1200 bps levels is absurb. We are abusing the spectrum! We should be looking at
broadcast like teletext functionality. Have your PC constantly sniff the stream
to get what you want. Effectively, you turn on your packet s/w and all the
interesting messages are "instantly" available because they've already been
sniffed out of the air by your PC.

Hi Gary.

What do you mean by symbol overloading?  Multi-level signalling perhaps?
(like if a bit can have 4 levels instead of 2, you can transmit a byte
in 4 bits) or do you mean having the same "symbol" represent more than one
character, and using shift characters when necessary?

The latter is an example of character set compression, and while useful
on occasion, isn't what I'm talking about. What I mean by overloading
is that one transmission symbol represents more than one bit. The classic
example is QPSK. Each symbol represents a dibit, IE two bits. So that
for 1 baud (symbol/sec) we are actually sending 2 bps. We can generalize
this out to any degree of overloading we like, and call it m-ary transmission.

QPSK is particularly attractive, however, if we Gray code it. That way
it is antipodal, and gives us the same Eb/No as BPSK while doubling
throughput. (Antipodal signalling puts the two states for a bit the
maximum distance apart in signal space. This allows us to form a
maximal likelyhood decoding decision based on the minimum possible
Hamming distance.)

Assume that I is encoded with the first part of the dibit and Q is
encoded with the second part of the dibit. An example Gray coded
constellation looks like this:

                              Q

                     +(01)    |     (11)+
                              |
                              |
                    I -------------------
                              |
                              |
                     +(00)    |     (10)+


Note: I've taken some liberties with the cartesian axis above.
The crossing point has been offset to 1/2,1/2 for clarity.

Note that the I bits are the maximum distance apart in signal
space, and the Q bits are similarly the maximum distance apart.
Symbols are antipodal along both diagonals. When the transmission
symbol makes a single transition from one dibit position to
another, two bits are transmitted. The likelyhood that either
bit is in error requires the corresponding distance vector to
traverse the maximum possible distance, so error likelyhood
is minimized.

BPSK would correspond to just an I vector, and thus only encodes
one bit per baud while giving the same distance metric in signal
space as QPSK. For the same Eb/No, QPSK transmits the same information
as BPSK in half the bandwidth, IE for equal information transfer,
BPSK would have to run twice the baud, and occupy twice the spectrum,
of QPSK. That's because QPSK overloads its symbols while BPSK does
not.

Other m-ary transmission encodings can have a greater degree of
overloading, but require a higher Eb/No because they can't be
made antipodal, and thus the signal space distances are less,
and stronger signals are needed to differentiate them from each
other when corrupted by noise.

OOK only transmits one half of the 0,1 pair, so its signal
space distance is 1/2 that of an antipodal coding, and its
performance in AGWN is 3 db poorer. (And that ignores issues
of coherent decoding, which adds another 3 db over incoherent
OOK at first order, and ignores more advanced signal codings,
such as trellis coding, which spreads the signal space over
a *much* larger area, and can offer gains of many db under the
proper conditions.)

  For example, quadrature phase shift keying.
  2 binary data streams. Stream I 1=0 deg. 0=180 deg. Stream Q 1=90 deg and
  0=270 deg. By shifting the carrier about 4 different pahse relationships,
  each position can mean any 1 of 4 different data combinations.

  Effectively at this point, the baud rate is 1/2 the symbol rate.

  With methods such as Clover, you can run a very solid (apparent) 200 bits
  per second on HF even though the actual baud rate is 40-50 which is the
  optimum value.

It's part of the PC/FlexNet software package. It's currently not on the

Jost (DK7WJ, initiator and author of the L2 kernel) presented and distributed
it at this year's ARRL DCC conference.
It's in a late beta state now, and is supposed to become final just before
the Interradio fair in Hannover at Oct ~21
To those who are interested, I'll mail the beta version (as long as I do not

Can anyone please help me?

        On the weekend of October 21st the Scout movement is involved in the
Jamboree On The Air (JOTA). We at the Phoenix Venture Unit (Kenton &
Kingsbury District) North West London, had arranged for a licenced
radio operater an a few of his collegues to use our Unit Den as a base
for a radio station. We have made all the arrangements for masts and
wires to be strung for aerials telephone lines etc. but he has just
been given the completion date for moving house and it is that
weekend, therefore we are without a licenced operator. Is there
anybody or a radio group that would like a change of venue with
opportunities for new contacts that would be willing to help us out,
time is of the essence with regard to arrangements and licences etc.
If you can help or require any further details please reply asap.

Most communications programs suitable for use with an external
telephone modem will also be usable with the KAM. Red Ryder
comes to mind for the MAC, just as ProComm comes to mind
for the PC. The basic criteria is that the program have a
"local" mode, for use directly connected to another computer,
or allowing direct keyboard "AT command" level interaction
with a modem. Terminal emulation isn't important, though the
ability to operate split screen is nice. But glass TTY emulation
is sufficient to work with a TNC.

Cabling should be the same as for a telco modem. You may need
to jumper DSR active all the time to control the TNC in command
mode, depending on the comm program you select. Better programs
can be configured to ignore these out of band signals and will
work with a simple three wire connection.

YES! Packet speeds of 56 kb are available via the WA4DSY (aka GRAPES)
56 kb RF modem. While the typical packet BBS is no more functional
than a telco PBBS, packet allows full network functionality, similar
to that offered by the internet, when fully functional protocols
like TCP/IP are used.

Of course, as is the case with landline PBBS systems, *both* ends
have to run the advanced modems and protocols for anything to happen.
This is the biggest drawback with VHF/UHF packet, you're constrained
to the lowest common denominator on the channel. If the retro set
insist on using 1200 baud, then you'll be stuck there too.

     Keith Sproul suggested using GPS for position control for an R/C
     helicopter:

     Won't the accuracy of GPS be to low here?  He could do differential
     GPS by comparing with a unit on the ground at a known position but the
     drift of +/- 100+ meters on a single GPS would cause problems unless
     he has a VERY large empty flying field.

     I am not sure that altitude can be done accurately enough by either
     means (triangulation and GPS) as the last 5 feet are what really
     matters.  You could try an ultrasonic system on the bottom of the
     helicopter for this.

Try SimpTerm.  Version 2.1 can be found on SimTel and Garbo, while a beta version
of 2.2 can be found at ftp://atl1.america.net/pub/users/k4gvo/simptr22.zip.
The doc file in the beta version isn't quite up to snuff, so if you want
to try it, let me know and I'll send you the updated one.

It is freeware and will run with all TNCs.

For those interested, I talked with 'Tom' at MFJ technical support
about Multicom. (1-800-647-8324) He was VERY helpful and agreed that
Multicom was lacking as
far as windows compatibility and that they were in the process of
doing a rewrite. Should be out about Christmas time.

They also have a new product - MFJ1213 that is an interface for
use with JVFAX70 for slowscan, fax, etc. He verified what I had
experienced. The UA741 op amp circuit that is touted in a lot of
articles as a simple interface for JVFAX and other programs is a
real bear to get working correctly. I spent a week of frustration
building and rebuilding that circuit to no avail. The MFJ1213
is supposed to list for $29.95 and will be ready for shipment in
about 6-8 weeks.

Robert,

   Don't dispair, although difficult, it can be done.  Last year I got
into
a competition with a fellow ham on who would be the first to connect
to MIR.  We limited our power to 5 watts on packet and worked hard
on many passes.  I finally got a solid connection to MIR with my 5
watt HT packet station.  My antenna was a no gain Radio Shack Discone
at 25 feet fed by lossy RG-58 cable.  (talk about stacking the deck

If it wasn't for AX.25, I am sure folks would try new things. AX.25
limits what you can do....

How so?  The KA9Q TCP/IP package has been running amateur packet IP
for years; it encapsulates the IP frames inside AX.25 UI (i.e.,
connectionless) frames (there's an option to use AX.25 virtual
circuits, too).  AX.25, in this case, simply serves as the MAC
level frame format.  AX.25 does limit some of the things you can
do, but I believe these things are usually orthogonal to the
actual data protocols.

Also, as I recall, the only requirement for the use of AX.25 is
in the automatic forwarding of third party traffic.  If you want
to experiment, you don't have to use AX.25 at all, but you simply
can't pass third party traffic under automatic control.

What's your point?  Am I missing something?

Yes. It'll work fine for Amateur TCP/IP since it is fully compatible...
that is unless hams do as they usually do and try to reinvent the wheel
and come up with their own non-standard standards.  Mobile-IP is already
well thought out and takes into consideration much of what packet deals
with. I'll be supporting Mobile-IP soon.

        Greetings all.  I am trying to find info on both the NMEA-0183
spec and the interface used by the 'Magellan Trailblazer' GPS reciever.
Acording to what little data I have the 6 pin plug is dc 11 - 13vDC with 4
pins for data.  trans data, rec data, signal ground and ???.  Also
what standard does this unit use?  ttl?, psuedo ttl?, or rs232 like the NMEA
spec calls for?  Any info would be great.  Thanks

Hi

I don't know what signal the Trailblazer uses, but I would guess it is some-
thing compatible with a PC's RS232 porti, and with RS422. NMEA is RS422,
which is differential.

For more info on NMEA and GPS look in the sci.geo.satellite-nav news group,
and ftp://sundae.triumf.ca/pub/peter. Peter Bennett has an impressive
collection of info and programs for GPS.

I'm try to put up an Internet gateway with a 1.1.59 Linux box and am running

  KA9Q NOS version 911229 (WG7J v1.09a4-Unix)

I have JNOS connected to a TNC through a serial device and to Linux
Internetworking support through a PTY Pseudo-SLIP connection.

I find that JNOS crashes on the telnet after SMTP does something and at
other odd times. If I need to dive in and fix the source, I will, but I'm
wondering if somebody can point me to a more stable binary.

I don't want to do anything unusual, just telnet and smtp.

  ftp to crompton.nadc.navy.mil and cd to /pub/hamradio/packet/wa3dsp

  j108dfd is the version that I currently run. And Doug has done a lot of
  work to fine tune and adding features. (Like real unix directory looks).

  In fact, it is running on a 12 MHz At right now. Stat says its been up
  and running, 55 days 13 hours. And free memory of about 70K or so.

I have 2 questions...and Ill get right to the point;

1.  I want to have a "true" vhf/uhf gate on packet. I have a Kantronics 9612,
and a Kenwood TM-241a for the VHF side. Im getting ready to buy the 440 rig, a
Kenwood TM-451a (9600 packet ready from the back panel). Ive heard talk that
this radio is not suitable for 9600 baud operation...is that true?

2.  My antenna is a Diamond X-500ma (dual band) running into a Diamond
duplexer. While I dont know the operation of the TNC yet, is is possible to
transmit both rigs, at the exact same time?

Many thanks

It depends on your definition of the boundary between "Good T/R" and
"Poor T/R".  The T/R switchover times of current "9600 ready" are usually
not as good as those of the purpose-designed dataradios (D4-10, Tekk).
You may find them "Good enough", but they are certainly not "Good".

Even worse: many Kenwood transceivers transmit transients when being keyed,
this causes interference on neighboring channels.  This is a real
problem in interlink sites (that operate a bunch of transceivers on
closely spaced channels) and when using separate local access frequencies
for separate coverage regions.  "plops" can be heard on nearby frequencies
when those transceivers keyup.

I think such effects should be considered as well when testing transceivers
on their suitability for packet radio use.

It is a pity that you can not just select that filter for "SSB narrow".

With my IC-736 I am using following trick when QRM requires 250 Hz filter:

KAM: Mark 700, Space 870
IC-736: Split, VFO A : CW-N at QRG, VFO B: LSB at QRG, DeltaTX: 800 Hz

The only drawback is that you have to remember to press "Split"
a couple of seconds and hold XFC while selecting LSB every time
you QSY.

Hi all,
It has come to my attention that the release of version 3.0 of UltraPak,
the Windows TNC driver software, contains some ambiguity over the cost of
registration.  Both twenty and twenty-five pounds is quoted as the fee.
Please accept my sincere apologies for the confusion - the CORRECT fee is
twenty pounds sterling.
73, Tim.

Hello,

I have asked this question before but have lost the notes I made from
replies, sorry.

I have ETHRAX25/WINPKT/TRUMPET/Mailers/FTPers/POPers/TELNETers/etc.

How does all this connect (software wise) to my MFJ1270B (currently TINY2 as
MFJ getting 4800 modem fitted)?

I was able to load ethrax25/axconfigure_program/winpkt and then when TRUMPET
was loaded watch data fly by when TRACE options where marked!  However,  it
was all in HEX and no callsign/ip_address where to be seen.  Like wise,  I
was not able to access the outside world via the IP services available on my
machine.

System is....

386SX 25 MHz 4MB RAM
Windows4Workgroups v3.11
DOS 6.22
QEMM 6.02

JNOS 1.10l functions flawlessly under Windows.

Any help appreciated.

A friend of mine and I each built one, both experienced the same poor
spurious performance.  All synth had many huge spurs.  Some shielding
of the VCO and decoupling helped...a little.  We never used the radios,
there just weren't clean enough in receive and transmit. They were a
good education in kit building and debugging tho...

My recommendation is to avoid the unit unless they have made major
design
changes since the original radio (the 2-m version failed the transmitter
spurious output test -- see the QST review from about a year ago).

I built one of these for a friend, and I also noted the very noisy
transmit audio.

I tend to believe the noisy transmit audio is due to the use of a
fairly noisy op-amp in the loop filter and audio chain driving a
VCO with a fairly high sensitivity.  The VCO gain is in excess
of 10MHz/V over most of the range;  less than 100uV of noise in the
op-amp output will result in about 1KHz of deviation!  This noise
will also show up in the receiver LO and degrade the receiver
audio, too.

Ramsey do a "sort of" kit - it is sold as a TNC kit here in the UK (not sure of
its descritopn over in the USA) but it is actually just a modem plus packet
software. It wouldn't build up to be a TNC is the same sense as a KPC-3 or
Tiny-2 etc.

There are several TNC kits over here in the UK - drop a message via the ham
network to packet @ GBR or (perhaps) kits @ GBR.

Anyone have any luck in geting JNOS and AX25 to work in Windows 95? I've

Tried TFPCX and that locks up.

Hey, has this been changed by G8BPQ?  At what revision of his code?

I wrote software that communicates with a BPQ node on ethernet, and the
last time I checked the packet format was:

>short                   length_of_data_in_the_level_2_frame plus 5
>char [14-400 odd]       the_level_2_frame

i.e. the 5 bytes of data were counted in the length, but were not actually
sent in the frame.

Needham Electronics makes avery good EEProm reader and burner.  I don't
know if that is exactly what you want, since an Eprom can be used only
once, the EEprom being the one that can be reused.  Anyway, I bought mine
from them for about $150.00.  I don't remember the address offhand, but I
have seen their ads in various electronic and ham radio magazines.  If you
are into building projects, many of them use EEproms and make the source
code available.  Then, all you have to do is grab the source code, load
the program and burn the EEProm.  Oh -- one other thing -- the one I
bought requires a PC slot.  It is really simple to use, and really handy
for off the wall projects.

Ditto. But it does microcontrollers and EPROMs too. More on that later.

PROM = Programmable Read Only Memory
EPROM = Erasable Programmable Read Only Memory
EEPROM = Electrically Erasable Programmable Read Only Memory

'Tis the PROM that can only be used once. As EPROM has become such a part
of the lingo that we often forget its meaning, many PROMs now come with
the tag OTP for One Time Programmable, also if you want thousands of a
part and can stand the lead time one can buy "mask programmed" parts with
your code right on the die.

DigiKey and Tucker also sell the Needhams' programmers. Think Tucker even
discounts it.

Please don't burn the source code into the EPROM, it won't run. Compile or
assemble first. Load object code into your EPROM programmer.

Also there are appearing enlightened hardware vendors posting firmware
upgrades on BBS's and ftp sites. Adaptec comes to mind. Need a BIOS
upgrade? Have a PROM programmer? Download the new version, blast your own
PROM, and away you go. This is such a neat thing that many modems and
motherboards now have FLASH memory which is like EEPROM but different, yet
still allows you to change the firmware without a programmer.

Intronics makes a good eprom programmer and the price isn't bad either at
$130 for the pocket programmer.  YOu can contact them at 913 422-2094 for
more info.

An eprom can be burned more than once, you get an eraser to erase them,
that's what the clear spot in the middle of the eprom is for and also why
you cover it when you're done burning it, you don't want ambiant light
erasing it over time.

That's news to me!  You can only use a OTP ROM once (One Time Programmable)
but you can use an EPROM many many times. You just need a UV light source to
erase it.
An EEPROM or E2PROM or E (squared) PROM is electrically erasable and is
available in both parallel and serial versions. Alternately a FLASH ROM is
also electrically erasable.

I do agree that Needhams makes a good inexpensive progarmmer. I have an old
one and it still works quite well.

I prefer serial port burners, because they don't require a PC. I can
connect them to a Macintosh or a Sun SparcStation.

This has been available for at least 5 years.  It is in everyday use on
the packet satellites.
Unfortunately there has appeared no production-quality broadcast server
software for linkage to a packet BBS yet.  People seem to work only on the
reception software, and the code running on the satellites is not available
from the authors.

I have helped some people on the way to writing a server for use with
FBB and my version of NET, but nothing has appeared yet.
To my knowledge, only a very experimental program by a Japanese guy
exists.  It only does the actual transmission, not the management of
the broadcast directory.

This is what the Pacsat protocol does. It's fine for bulletin
transmissions, general file downloads, etc, but is rather wasteful
of spectrum for transmission of messages intended for only one
recipient. That's still better served by point to point transmissions.

I've recently got back on the air and linked my Icom 2/70 handheld up to
a PK232 to experiment with packet.

The thing is my handheld is a bit OTT as a single freq, packet, transceiver.

What I'm looking for (I think) is a dedicated radio that can act as my packet
radio, transmitting approx 10W. What should I be looking at?

Any suggestions for second hand mobile rigs or ex-PMR (although I've never done
any conversion work and am a little apprehensive of this route) or possibly a
specially designed packet rig (if such a thing exists - I vaguely remember a review
in an old HRT of a KAM 2M packet?) welcomed.

73s and thanks

The good news is that older, crystal rigs are often better performers
than newer, synthesized ones.  The reason is that a synthesized radio
takes a short period of time to lock on frequency while a crystal
radio is much faster.  This allows you to set a much shorter TXD
(transmit delay).

Old land mobile radios generally work fine, but you need to specify
what baud rate you are using.  Virtually anything works at 1200 baud
where AFSK is being used.  When you get up to 9600 baud and beyond,
generally pure FSK is used and only certain radios work well.  For
9600, many over on this side of the pond use Motorola Moxies or Maxars
which are excellent at 9600 with very little modification. I don't
know what is available in the UK, but maybe someone else can chime in.

Hi,

I am looking for the microphone vendor of the Ear-Mic which apparently
has several advertisements in this month's QST.  This microphone can be
attached to a 900 MHz Freedom-1 unit which provides excellent mobility
for communication.

I do not have access to the QST magazine, nor do I know where to get a
copy of it.  If someone could please send me information on how I can
contact this Ear-Mic vendor, I would really appreciate it.

Thanks,

Ken

Hi!

I just read the general HAM radio FAQ in 3 parts, where the last one
talked about a FAQ specific to this rec.radio.amateur.digital.misc group.
I don't find it anywhere :-(
(except the Guide_to_the_Personal_Radio_Newsgroups that I found under
the group's archive on rtfm.mit.edu -- nothing specific to digital radio
telecomms)

Please, someone give me an URL or mailing-list address to get it, or
whatever, I would like to get some general informations before I start
asking dummy questions :-)

As I am a real newcomer to the topic, it would be nice of you to indicate
me the most useful links that would explain basics of amateur radio
related to computers, how to make both work together, etc...
Basically, my dream would be to make up a connection similar to the
cellular/modem service by my own... Is that possible? Where to learn how
to do it? What other marvels can be done?

I saw a LOT of links to HAM stuff on Yahoo, but that's the problem, it's
too much, and I am unable to judge myself yet what is useful and what is
not in my case.

 As I am studying in Electrical Engineering, I am not afraid of techno
talk ;-) Actually, as a Linux and HP48 user, I am kind of used to it :-)

Thank you for your help,

Michael...

The software that came with my KPC-3 was a little terminal program
called PACTERM.  It works, but barely.

If you have a good modem program like Procomm-Plus, it will work with
your KPC-3.  It will also be much more user-friendly and powerful.

There are several other programs on the market that are designed for
the Kantronics line specifically, but I haven't used them.

Until I recently changed TNCs, I was using TPK (in conjunction with the
local BBS using F6FBB software) as my terminal program.

Have fun..

The easiest way I found is to use the FCC's fax-back service, you need a fax machine
or fax-modem # to give to it.

Call [phone], ask for form #000610 & give it the phone # to send it to, it
calls the # in a few minutes & sends you 3 pages, unfortanatly you have to mail
it back to them. Good luck.

Part 97 watchers 'n' Interpreters:

Does the new addition mean that any "publicly documented" waveform can

and MIL-STD-188-110A (serial-tone and other "advanced" waveforms)?  Since
anybody can get a copy of these from the Government Printing Office, it

I haven't seen any new additions (you have a source we can read?), but in the
past, you could use any unspecified code in the bands indicated.  That usually
mean't that HF was restricted to specified codes.  Can't use TADIL-A in the
HF Ham bands :-)  But usually 70cm and above is unrestricted for the most part.

Ken,

This is how I understand this issue:

300 baud is not necessarily equal 300 bps. MIL-STD-188 serial
modems generally runs at low symbol rate, i.e., 75 baud, however, packs
multiple bits per baud and thus effectively can be as high as 1200 bps at
75 baud in raw encoding. The effective bit rate drops once FEC or
redundancy is added. This mode does occupy greater bandwidths as you
indicate. This is a bit more complicated as it may appear as it involves
the issue of automatic stations that has a 500 Hz bandwidth limitation,
I'll leave that for the moment, however.

The 300 baud regulation thus still remains. The amendment regarding
public release of coding/protocols only clears up the bit of confusion
regarding the use of special codes and cyphers, such as ECC and protocol
specifics. In this respect G-TOR details have been published, Pactor I,
and as you indicate, the CCIR modes (RTTY, AMTOR). We have yet to see
CLOVER II and Pactor II (if I missed where it is published, please
forgive my ignorance and let me know where), but I have good faith
that all will come in good time. I don't think there ever was any
intentention of using prorietary technology on the amateur bands?

Let me see if I can clarify. This "new" rule is almost no change at all.
First, you have to define any HF digital transmission by its three components:

1) The data coding (the "code")
2) The protocol
3) The modulation scheme

The first of these, the code, defines how graphic symbols (characters) are
mapped into bits. The use of these is regulated by 97.305, 97.307 and 97.309.
For HF, the relevant rule is 97.307(f)(3). It requires that data be sent
using one of the codes: ASCII (with extensions for non-English), ITA2 (Baudot)
and the 7-bit AMTOR/SITOR code. What this means is that you *cannot* legally
send non-text data on HF. Sorry.

The protocol is simply the extra (noninformation) bits sent to control the
link. All HF digital transmissions use some form of protocol--even RTTY,
where the protocol requires the use of start- and stop-bits and defines
the order in which the data bits are sent. There has not for many years been
any rule that restricts the protocol being used. That's why we were able to
use AX.25, G-TOR, Pactor and Clover legally, even before this new rule, as
long as the data being transmitted was encoded using one of the legal codes.

The allowable modulation methods for HF digital are regulated in 97.3(c)(2)
and 97.3(c)(7).

The only thing that's new here is the bit about "documented publicly," and
that's a new *requirement*, not a loosening. (But almost any form of
publication--probably including posting on Usenet--will serve.)

For a copy of the ARRL Bulletin on this subject, see:
http://www.arrl.org/w1aw/1995-arlb094.html

Finally, while I don't know the details of MIL-STD-188-141A, I seriously
doubt it uses signalling speeds of 300 baud and above. >300 bits per
second, yes, but 300 baud, I think not. If it does, it won't work too
well on HF.

a precursor to ftp even; the name implies that it was for transferring
files, not mail specifically.  Of course mail could be a file but doesn't
have to be...my question is basically what is wrong with completely
reproducing the internet on packet radio, using _all_ the same, most
current protocalls, and letting sleeping dogs like uucp lie?  Obviously
I'm not an expert on the protocols and standards... :-)

And what do you mean by the "store and foward" thing?  I do know for a
fact that my received mail on a Unix system is stored in a file, and sits
there waiting as long as necessary for me to read it.  Presumably, at
in-between machines that are somewhere in the path of a particular mail
message's trip from source to destination, the mail message is written to
a file temporarily, and then the machine tries repeatedly to forward that
file to the next machine where it's supposed to go.  When it gets some
kind of "ack" that means the mail has been forwarded successfully, then
and only then can it delete the message.  That would be store and
forward, and i don't see any alternatives.  UUCP must not be the only
protocol that implements such a method.

: For this to work we need three things:

: 1) Cooperation from the BBS software authors to implement the new
:    functionality (specifically SMTP, NNTP, and RFC822 based mailers).
:    This has been done many times over, and much of the code is available
:    and can be re-used for this application. (Check out your local land-

: 3) A user community willing to accept change (a new addressing format).

: I hereby step forward and volunteer to take on #2 above. Who else is
: willing to contribute to moving the BBS mail/news environment forward?

I am!  What we have certainly sucks.  As for old dogs not learning new
tricks, well, I suppose using packet at all must have been a quantum leap
for them at some point.  If they learned that new trick why not this one?

Of course, I realize one of the primary barriers is that to make best use
of TCP/IP and Internet-style mail forwarding, as a network user (as
opposed to a sysop/provider) you'd need the right kind of client, be it
JNOS or some hacked Internet tools, or better yet, Linux and completely
unhacked Internet tools.  But what about this:  provide Unix shell
accounts for the old dogs, so that they can just connect to their accounts
as if they were connecting to a BBS, and then use the BBS's Internet tools
like Elm or Pine or a newsreader to do their email.  Then they don't have
to modify anything at all on their own computers, all they have to do is
learn how to use the tools at the remote site.  Compared to the current
helter-skelter, abominable user interfaces that every conventional AX.25
bbs I've ever seen has, this should seem easier to them, not harder.  And
when they're ready to upgrade their own machines it would be an easy
switch at that point.  I could provide this service easily enough, when at
last I get some kind of BBS running, and it seems easier at first glance
than throwing out the baby with the bathwater and designing something new
and hokey.  Then again, there may be reasons why Internet style protocols
don't work as well on packet, I just don't see them yet.  And as an
object-oriented software designer I believe strongly in re-use!  If
there's no reason not to, why can't we just see packet as a replacement
for the ethernet card, and abstract out the differences at the driver
level, so that high-level software can pretend it's talking on the Internet?

The UUCP protocols biggest ill, is its use of 64 byte packets.  It was designed
for 300 baud modems.  Which come to think of it, is basically what we have
on packet radio!  (1200 baud, 9600, etc; they all are slow slow slow).

>And what do you mean by the "store and foward" thing?

UUCP uses bang used "bang" addresses before the Domain Name
System was invented.  To get mail from your machine, you directed it
yourself.  There bacame great hubs that everyone used as a base.
You would state your address based on this hub.  For example, my
first uucp address was ihnp4!killer!disco!ssampson.  That is, my
UniFLEX UUCP machine called disco, sent the mail to killer, and
killer stored it until forward time to the big hub called ihnp4.  We do
the same thing today with the '%' bang.  You can send your mail
to me via [e-mail].  What this does
is SMTP it to wb5cqu.  He then stores it, and then forwards it up the
state to n0els, who stores it, then forwards it to my box.  All SMTP via
TCP/IP, but manually directed.  Much better than trying to SMTP direct.

>: For this to work we need three things:

>: 1) Cooperation from the BBS software authors to implement the new

Just do one thing.  Program in modules and processes.  Don't make a big
program to end all programs.  Choose a multi-tasker, and then build the
5 programs that must work together.  These huge programs that have to
fit in 512k of memory are stupid.  MSYS, JNOS, etc, are obsolete.  They
are chains around our neck.

Yes but I admit I was using the 30 watt amplifier from Radio Shack. My
setup is a HTX-202, Radio Shack 30 watt amp, Kantronics KPC-3 TNC,
Discone antenna that is used for both 70cm and 2m via a duplexer. I've

That's cool, almost all packet BBS systems allow that. The FCC considers
ham packet BBS systems as message store and forward systems. The originating
station operator for the message and the first forwarding BBS station
operator are considered primarily responsible for the content.

>And, to go further, what about if that bbs had land line modem access.
>What are the legalities of that.

That gets trickier. If dialup landline access is permitted, then messages
introduced from landline callers have to go out under the call sign
of the BBS owner, as third party traffic, since the BBS station is
now the originating station for the message. It doesn't matter whether
the callers are hams or not. *Their* stations are not originating traffic
on radio, so the BBS isn't acting as a store and forward system for
packet traffic from them under FCC rules. Instead it is acting as the
originating station for third party traffic.

Wormholes are an exception. If traffic originates from an amateur
station, is picked up by another station (first forwarder), and
relayed by wire to another station which retransmits it on radio,
then the wireline link doesn't change the second forwarding station
into an originating station. Wormhole operation is no different in
principle from split-site repeater operation where there's a phone
line linking receiver and transmitter.

The key issue is, what station *originates* the traffic? If it's
the BBS station, then it's either first party traffic, if it's
from the licensee of the BBS station, or third party traffic if
it is from any other party using the BBS station as the origination
point. But if the traffic is received by radio from another station,
then the BBS station is merely acting as a store and forward relay
and that traffic isn't considered a third party origination by the
FCC.

This area can get subtle, like how many angels can dance on the
head of a pin. If we said that third party traffic consisted of
*any* content retransmitted for a person other than the licensee,
then ordinary repeater operation would be considered third party
activity. But it's not. The *reason* that it is not is that third
party traffic has to be *introduced* to amateur radio for a third
party by an amateur station. So, for example, if an amateur lets
another person speak on his radio, that's third party, or if a
repeater station *introduces* a third party by phone patch, that's
third party, but ordinary relay of one amateur station by another
is not third party.

Bringing this back to landline access to an amateur station, it's
no different in principle from phone patch operation. Messages
posted by people from the landline are third party content originated
by the BBS station. Messages relayed from other amateur stations, even
indirectly via wormhole, are not third party beyond the first forwarder
(as far as the relaying station is concerned, though they may be third
party to the originating station).

Since all third party traffic must be under the direct supervision
of a licensed control operator, BBS systems allowing phone line
access must be *manned*. BBS systems acting merely as store and
forward systems for other amateur stations do not have to be manned.
They can operate under the FCC automatic operation rules.

A couple of notes. Operators don't have call signs, amateur stations
do. The FCC regulates transmission by amateur stations. So just because
Joe Blow is a ham, he can't originate a message via landline under his
station's call sign, because his *station* was not involved. Instead,
he has to act as a third party under the call sign of the station
actually originating the traffic.

Side note, of course if he is *controlling* his station by wireline,
then he can originate messages under his station call sign. This is
just remote control operation, and falls under a different part of
the rules.

YES!!! ARPD124.ZIP - the Amateur Radio Packet Door v1.24. Available on
ATTENTION to Details BBS at 909-681-6221.

From your Users' standpoint,  operation is very simple. Just set it up
as a Door, wait for the program to initialize the TNC, and they operate
it just as if they were using it from their computer.

You  may  also use the door while logged on to the  BBS  locally,
just as any user can.

ARPD is well written. Ease of operation was a prime consideration - as
was low Sysop maintenance. Once installed, ARPD requires little
attention. All operations are handled automatically by an intelligent
operating system requiring little specialized knowledge on the
part of the SysOp or the user.

When a user accesses the door, the call sign of the TNC is changed
to that of the user. This allows him to log on to packet BBS
stations  and  receive traffic as he would from his own home  station.
The  call sign is changed back to that of the System Operator on  exit
from  the  door.    This  has an added advantage of  making  the  user
responsible for his own actions on the air.

PLEASE use some sort of APPLICATION with your Users in order for them
to access such a Door! AND - you should have a photocopy of their
Amateur Radio Licenses at your station. I'll post my Application as an
example, if you would like.

Hallo, I am using PTC II. I just want to make skeds on 40 m
at around 15.30 hours UTC in this mode between W6 and DL
to check its performance under difficult conddx.
Am using TS-50 and vertical Delta loop, can read CW from W6
at that time of the day from 339 to 579 (RST).
Any suggestions are highly welcome! 73 de Nils, DK8OK

That one is certainly covered by a patent...

----------------------------------------------------------------
Does anyone know when that patent was filed?
I can probably point to prior art that WAS a trade secret to invalidate such a
patent.

IMHO most software patents could be invalidated because of prior art but most of
it was never published.

On a related note, it would seem logical to me that if an "invention" is
invented within a year or two by two inventors who developed something
independently, then that patent should fail on the grounds that it is obvious to
a person skilled in the art.

Just because no one has ever done something before does not by default make it
non-obivous to a skilled person.

Has anyone had any luck getting PCPakratt to work with a PK-232
under Windows 95? The software doesn't seem to want to talk to
my COM2 port. In fact, most of the time it locks the system up, requiring
a reboot! I've tried playing with the various port settings to no avail.
All works fine under native DOS, Windows 3.1 and OS/2. Any ideas?
Thanks

If you set things up with axattach, folks with tcp/ip (jnos or whatever) should
be able to telnet into your box and get the login prompt.

  Well, it certainly could since I missed the keyword "Linux" in your first

        Typical Addresses for the serial ports are...

        Port            Address         IRQ

        1               3F8             4
        2               2F8             3
        3               3E8             4
        4               2E8             3

There are a number of "aftermarket" boards that allow you to "customize"
both the address and IRQ of a serial port.  JDR microcircuits offers
one that I am aware of that allows both of these options.  I also
saw recently a board by SIIG at CompUSA that supports non standard IRQ
from 2 to 15 (could not tell if it supports non standard addresses).

Another option for a non standard is the board the Mouse Systems offers
to change the IRQ of a serial mouse.

That is of course true, but there is also validity in the original comment.
In the past, all the new releases were "developer" releases, but they
usually worked.  Nowadays it happens fairly frequently that a new release
does not even compile.
I can understand that someone without C development experience finds the
new stuff scary, and it certainly was different "in the beginning".

I have another dumb question. I have heard something lately on 40m
that sounds like a mad tea kettle blowing off steam. I know what
pactor, gtor and all those sound like but I dont know what this one is.
Is this clover or some other form of new modulation (pactor II)??
Or am I hearing some other junk?
I heard it last night on 7.070 and 7.130.

I'm curious how the VCO radiation is affecting the operation of the
PLL.  Certainly the reference spurs are expected as a result of leakthrough
in the loop filter; are the spurs much higher than you expect?  Did you
check the loop filter to make sure it was working correctly?

Yeah, there's apparently way too much gain in the front end
with way too little selectivity.  I'm surprised it works as
well as it does.

I think that the only thing you have to do is to convert the logic
levels of your serial port (because C64 works with TTL levels, unlike
the RS232 modems). I suggest you to use the MC1488 and MC1489 IC's.

I have a digicom/baycom modem diagram on my web page at:
http://nis-www.lanl.gov/~jdport/
which shows how to easily wire a connector for either a C64, PC, or
both(!) to your existing modem.
In my experience about half the PC's extant (not including Dell) will run
BAYCOM with a digicom modem with no alterations whatever except for adding
a 25 or 9 pin serial connector properly wired to engage the PC.
If you get it wired and running and it transmits but shows no receive
activity even on a busy channel then you will usually need to add a TTL to
RS232 level shifter (max232, etc) on the receive data line to make it work
on receive.

I don't think the ASP is user-programmable. Proper DSPs on sound cards
like the Cardinal can be used for CW filters, modems, etc.

I did not see the particular ear-mike ad mentioned, but I just wanted to
pass along my limited experience with them:
I find that most of them (even the expensive ones) are appallingly low in
transmit audio.  They pick up noise outside your ear much stronger than
your own voice.  You have to speak very loudly to be heard and even then
most of your contacts will complain about "low audio".
I gave mine away to a young bicycle-mobiling ham who had a higher pitched
voice than mine and it seemed to work only slightly better with him.
The 2 or 3 others I know of who have tried these mikes had similar
problems.
I know it can be made to work:  The "ear-mikes" that are used on the cheap
Radio Shack 49 MHZ transceivers work great, but they have a sort of soft
plastic flanged earpiece that comfortably seals (at least in my ears) the
exterior noise out.  But none of the separately-sold mikes I've seen are
made this way.

1. Anyone using the P38 card from HAL? If so, is anyone having any problems
with data transfer in the Pactor mode? I can link just fine with other
Pactor stations but have difficulty in phasing or otherwise properly
connecting and either I see each burst as an error or the other station
sees errors and keeps sending RQ's back. If I discontinue the link and
try again it often works OK for a while. Then after several minutes the
same thing can happen and messes up the QSO. Appreciate hearing any
comments.

2. I know there are a number of recommended freqs for Clover operation
such as 14065.5, 10136.5, and 7065.5, but the ones I have heard for
80 meters don't seem like the best place to operate. Any thoughts on
Clover calling freqs on 80 meters?

        I need some help.

        The problem involves the "Print This Channel" feature (function key
6) provided by Kantronics' HostMaster II+ (ver 3.11).  When this feature is
selected, the characters printed on the printer are echoed and a
carriage-return, line-feed is not added to the end of each line.  For
example, instead of "HAD" the pattern "HHAADD" is printed.  I'll leave the
carriage-return, line-feed problem to your imagination.

        As a stop-gap, using the "Save to File" feature (function key 5)
and selecting PRN works just fine.  This scheme directs the data to the
printer, does not echo characters, and places a carriage-return, line-feed
on the end of each line.  While it this circumvention works, it is more
cumbersome.  But more important, why doesn't the "Print This Channel"
feature work properly?

        The printer is an Epson LQ-570.  Host is running DOS5.0/Windows3.1.

I need some help (schematics? theory?) building a radio.  I needs to be
completely (and I do mean completely) controllable via computer, in fact
an internal 8-bit interface would be ideal.  The TX amps can be outboard,
however.  It needs to operate from 108MHz on up to 130MHz or so.  I also
need some help building a receiver capable of 500KHz to 2KHz as well as
GHz ranges, and possibly the 75MHz range.  This is for aviation purposes,
and if anyone has any ideas help would be greatly appreciated!

Ralph,
You have no idea of the magnitude of the task you describe.  The transmitter
isn't nearly as much of a problem as the receiver.  For the transmitter, a DDS
would probably do the trick (Direct Digital Synthesis).

I recommend that you buy a copy of "The Radio Amateur's Handbook", published by
the American Radio Relay League in Newington, CT.  It costs about $30, and will
give you all the theory you need to begin understanding the questions you'll
need to get answered.

Keep in mind that a task of this magnitude, if it is to be done with the proper
reliability required for aircraft use (where life is at stake), usually
requires a team of engineers who have devoted their lives to the topic. While
you might be able to do it alone, as some advanced Hams have, I think it might
be more than you bargained for.

I can't say WHAT the PK-96 has in it, but I do know that the K9NG was reworked
a year or two back, and vastly improved over the original.  Compatibility
problems are not the huge problem they were.  Not sure what the changes were
(Can anyone tell me?), but have heard praise.

You simply must try KaGOLD from Interflex. A Test Drive version is
posted on ATTENTION to Details BBS at 909-681-6221. The absolute finest
software package available for the KPC-3 (as well as all other AEA and
Kantronics Single and Dual Port TNCs).

Look for KAGOLDTD.EXE or KADEMO.ZIP on ATD BBS. I have also received
permission from Kantronics to offer you their demo diskette, with
diagnostics software and product information files - its filename is
KANT-TNC.ZIP.

A few of KaGOLD's features...

      Excerpt from "Performance Software" -- GOLD Software User Manual
      Copyright (C)1993,94 by InterFlex Systems Design Corporation
      All Rights Reserved

  Quick Summary:

  ALL   For all users, GOLD (Pk, Ka, dsp, etc) adds the ability
        for you to setup your station as a callbook server,
        conference bridge, general file/information server, as
        well as support for ANSI pics, restartable file
        transfers, and more.

  Version 9 represents a significant departure from the earlier
  versions of GOLD software.  Commands from remote stations are
  now allowed, two screen modes are supported for every session- -
  the normal text character screen and a new ANSI graphic screen
  -- direct interface to callsign databases (SAM, Buckmaster, QRZ)
  is supported, restartable file transfers, and improved operation
  in Windows and other multi- tasking environments, and support
  for CW announcements through ad-lib type sound cards.

      o   Callbook Support for four (4) CD based systems, and the
          SAM disk-based callbook. Users can lookup callsign data,
          the program does lookups automatically, and remote users
          can request callsign data making the station a callbook
          server (if remote commands are enabled and the
          appropriate callbook cmd file exists). Callbooks
          supported include Amsoft CD, Buckmaster CD, QRZ CD, SAM
          CD, and SAM Disk based callbook.

      o   ANSI Graphics supported on all sessions simultaneously.
          Pics are saved automatically if desired, and the program
          can "flip" to graphics mode automatically. No other
          program offers simultaneous, multiple ANSI picture
          receiving.

      o   Restartable YAPP and GOLD transfers. YAPP-C is
          supported, and restartable transfers are done
          automatically, as the program determines if the remote
          station supports these features. Partially complete
          files have a text header that makes it easy to determine
          which files are only partially received.

      o   Conferences can be started remotely, allowing your
          station to be a conference server. Users can switch
          conferences, start new conferences, and leave the
          conference and remain connected if desired. They can
          also send messages directly to other stations in the
          same or different conference.

      o   Remote commands, including user defined commands in CMD
          files.  This allows you to create a file server, ANSI
          pic server, radio mods server and more. The ability to
          create commands that remote users can issue opens a
          whole new set of outlets for for your programming
          creativity.

      o   Morse messages can be directed to an Ad-Lib compatible
          sound card. Also, CW pitch can be set by the user, both
          user options are in the SETUP area.

      o   Network View lines now show headers in low-video, and
          text in high-video, making it easier to distinguish
          headers from text. This is done automatically.

KaGold is Ok I use it but it is over priced. There are
a number of other less expensive solutions for users that
don't want or need every feature known to man. The advantage/
disadvantage of KaGold is that it uses host mode of your TNC.
If you want all of the whistles and bells this is the best way
to go but for most users it is a waste. If you want to connect
to your local bbs and read a few posts there are a lot of
programs that will do that quite well. I have also uses Paket 6.1
it is much more intuitive than Gold and for a simple TNC like the
KPC-3 is more than enough for most users. These are just my opinions
and worth exactly what you paid for them.

No changing everyones TXDELAY would have no effect other than to slow
everyone else down. What needs to be done is have others slow down
their acknowledge response times (I don't remember the name of the
parameter). Unless you were a key node on the network I would say it's
not worth slowing down everybody. Buy a dedicated data radio like a
TEKK900, Kantronics D4-10 (70cm) or MFJ (2meters). The TEKK and MFJ
are less than $130.

Packet length and window size are negotiable at link establishment
time for G protocol (the most commonly used).  The fact that many
implementations are tuned for a low speed & error prone link is a
historical fact; but it isn't a requirement.

I don't have my copy of Chesson handy, but I vaguely remember that 512
byte packets were ok, and you could certainly have a 7 packet window.
That's enough to hide the turnaround and latency of even V34 modems.

could have several UUCP sessions going at once.  All that
store-and-forward should mean is that the distance an ACK has to travel
per packet is reduced, because the file transfer is a shorter distance.
Between store-and-forward nodes something like FTP could still be used.
As the ham network gets faster, you simply increase the number of hops
between nodes, and the limit of that as speed -> oo is what we already
have on the internet, ie someday we can get from source to destination
without any intermediate store-and-forward.   I guess this is pretty much
what this kludge you're talking about is, but we could use ftp rather
than UUCP, the only difference is that it's short-haul ftp, and the short
hauls add up to inchworm the file end-to-end.

Gary is slightly incorrect here; the TTL is typically set to 64 in
almost all IP implementations these days, and 255 is becoming more
common as the internet gets deeper and thicker.

Keep in mind that the TTL is NOT decremented when tunnelling encapsulation
is forwarded from router to router, so even the torturous paths that
packets take to get to some parts of the AMPRNet aren't really that many
hops away.

The internet is the world's second largest network (the public telephone
system is the largest).  We hams could steal some really good ideas from
it, if only more people were willing to adopt them.

I'm looking into setting up a packet bbs / node.  I have currently downloaded
G8BPQ node software & F6FBB bbs software, but was wondering if there was any
other software a bit easier to set up.  Or failing that can any one recommend a

Also is it possible to run a node / bbs using Baycom style modems, and if so
what extra software is needed to drive them.

Thanks

I am aware of ETHRAX25 which provides a Packet Driver interface for
DOS to a KISS TNC.

Are there any other Packet Drivers, or NDIS Drivers, available for
DOS/WINDOWS that interface to Packet Radio equipment, such SCC cards
etc.

The idea being that we should be able to use Windows and the wide
range of WINSOCK based TCP/IP software as clients to Packet Radio
based TCP/IP systems.

Any info greatly appreciated.

[Tnos] FTP Updates:

As changes are made, the files on "lantz.com" will be updated, as
well as those on the PacComm BBS. Check to make sure you are dealing with
the current version, if you are experiencing a problem.

You can also find the TNOS files on ftp.ucsd.edu in the directory
/hamradio/packet/tcpip/tnos. Most people will want to get them from this
site, since the lantz.com site is connected to the Internet via a 14.4
PPP line, and download times will be shorter with ftp.ucsd.edu.

Attached you will find modifications for both model Tekk radio's that improve
the receive and transmit performance at 9600bps. It's reported that both TEKK
and PacComm have been making some/all of these modifications. I have no idea
when they implemented these changes. Receiver IF tuning is important with
both receivers.

       Tekk Data Radio Mods for 9600 bps
             by John Bednar, WB3ESS
              Original Issue:12/93
              Last update: 5/16/94

TEKK KS-900L Receiver Mods (black case)
At the 9-pin interface connector add a 2.7k ohm resistor in
series with the wire going to pin 5. Next, solder a 0.001uf
capacitor between pin 2 and pin 5 of the same connector.


TEKK KS-900L Transmitter Mods (black case)
Solder a 3.3uf tantalum capacitor (observe the polarity) in
parallel with capacitor C31. The transmit requirements are not
changed so re-adjusting the transmit level will not be required.





TEKK KS-960L Receiver Mods (chrome case)
Remove chip capacitor C18 and replace it with a 0.001uf leaded
capacitor or chip capacitor.


TEKK KS-960L Transmitter Mods (chrome case)
Bypass the transmit limiter, modify the modulator, and inject the
audio into TP9 with the following steps:
1) Remove the wire attached to pin 4 of the 9-pin connector and
solder it to ground.
2) Solder the (+) lead of a 10uf tantalum capacitor with 0.2"
leads to the 9-pin connector - pin 4.
3) Prepare a 1.8" piece of wire with 0.2" ends and solder one end
of the wire to the (-) lead of the capacitor added in step 2.
Tuck the other end of the wire around the circuit board in the
corner. Don't use the corner where the BNC is mounted.
4) Locate the junction of C43, C92, and R41. Form the wire, trim
the end to 0.1" and solder it carefully to this junction.
5) Locate the junction of R43 and C47. Carefully remove the
solder from that solder pad. With a sharp knife cut the trace
diagonally between R43 and C47. Check your cut with an ohm
meter to insure that the trace is open. If you break R43, C47,
C48 or C49 don't worry because these parts are no longer used.
6) Locate potentiometer VR1 and turn it fully CW.
7) Re-adjust the transmit frequency and the transmit deviation.


A complete article with frequency response graphs will appear in
the January 94 Northeast Digital Association Quarterly. As of 10/95
this issue has not been printed.

        This is not too hard to accomplish if you run the TNCs
in their Host Modes.

With the AEA you will need to set converse to TRANSPARENT mode.  By
running in this way the CHANGEOVER character will transmit as normal
data.  To monitor the buffer of the TNC use the ZFREE command.  This
will return the number of blocks that are available in the TNC.  Using the
ZSTATUS command you can determine when the buffer is empty.  To switch
the link over in Transparent mode you will need to use one of two methods.

The first is available for AEA TNCs with firmware versions with at least
12-1-93 dates.  In these versions you can use the OVER command (host "OV")
this will cause the link to switch immediately,  regardless if there
is data in the buffer or not.

For the 3-5-93 versions of AEA firmware,  you will need to switch from
transparent mode back to converse and issue the CHANGEOVER character (normally
CTRL-Z).  This is not too clean but it will work.

Another point you might consider is that the OP response for the AEA
will return the current link status.  ie "IDLE".  If you find the
link is in IDLE you also can determine that the data has been sent.

For Kantronics it is a little simpler.  When running in HOST mode you
can POLL the TNC using the STATUS command,  this will return current
stream/channel connections as well as the available memory for both
ports.  If you "save" the memory available before starting a transfer
you can use this as a compare to determine when the buffer is empty.  A
simply

        if ((save_memory - current_memory) == 0)
                ChangeOverLink();

        (in 'C')

should do the trick.


Hope this gives you some ideas.  The advise is free.

Requires TCP/IP software and an IP address,e.g., 44.0.0.0 for Amateur Radio.
A protocol is a standard format or way of addressing packets to and from one
computer to another.

Hope this doesn't muddy up the water too much hi,hi. . .

Hi,
        As a SWL, I hear transmissions on 7032 just below amateur packet
stations from middle to late afternoon (E.S.T) in Melbourne, Aust. These
sound (to me) like PSK. Are they amateur transmissions ?? What is the
mode ?? What is the rate ?? Or is it GMSK ??

I hear similar transmissions on 20m, around 14100.

Thanks for any assistance.
Paul G.

I am using jnos110L and it works fine, I just used "My Computer" and
went to the directory where Jnos110L was, created a shortcut and moved
it onto the desktop and it runs just fine. What I am looking for is a
"Mailer" program similar to PMail used with OS/2.

See QST, October 1993, pages 73, 74 and 80.  To be fair, after the ARRL
called Ramsey about the problem they were provided with a fix; but, to
quote the review, "The close-in spurs, even after the modification, are
fairly significant."

        Well,  I would say that reference spurs of -6dBc are higher than
        expected.  If the loop filter was at fault, then shielding the
        VCO would have no affect.  As further evidence of VCO radiation,
        when I had the top cover of the unit off and had a receiver tuned
        to the VCO frequency,  I could rattle metal tools together off the
        bench up to two feet away and the VCO would produce microphonic
        responses.  And a spectrum analyzer with a "sniffer" probe would
        pick up a strong signal in the general area.

        I suspect that there's so much of this radiation being coupled into
        the PLL circuitry that it's either modulating the divided VCO signal
        going back to the PLL chip or somehow modulating the charge pump
        output, perhaps driving the filter into nonlinearity.  Whatever the
        mechanism,  it doesn't seem to be related to a bogus filter,  and
        I did fiddle around with that.

        I'd be interested in hearing other possible explanations though.

>>I have friend-of-a-friend word that Ramsey claims it works on 9600 baud
>>packet, but nobody has actually been able to get it going quite right.

Some time ago I bought their kit.  I found that the receiver suffered
from
many spurious responses which, given right (wrong?) packet frequency
would
make it pretty useless.  I did get it to receive 9600 but had a pretty
strong signal to work with and didn't make any performance measurements
so
I can't really comment on the receive performance.  The transmitter was
a
disaster!  Because they have no shielding anywhere in the radio the
transmitter output got back into the PLL and the resultant signal
resembled
broadband noise.  I wasted a lot of time trying to clean that up and
never
was successful.  I believe that  taking the time to build a good shield
around the PLL would have solved the problem but there are problems with
the board layout that make it a  difficult thing to do.  I did find a
few
minor design errors which resulted a very long (for 9600 packet) TR
turnaround time.  They directly modulate the VCO, like most radios, so
the
transmitter will distort the signal.  I never got far enough to worry
about
that.

A friend of mine bought one and had similar problems.  Both of us wasted
a
good bit of money.  Since then we have discovered the joys of converting
commercial (e.g., Motorola and GE) radios...they work!

My recommendation is to avoid the unit unless they have made major
design
changes since the original radio (the 2-m version failed the transmitter
spurious output test -- see the QST review from about a year ago).

Well, I picked up a couple of ARCNET AL-3351 at the swap meet.

I have been using NOS in a cheap 286 box here and talking to it from my
desktop PC thru a comport slip link. I would like to use these ARCNET
cards so I can setup some commercial TCP/IP software here (Don't cringe

..maybe WIN95!!!).

The question is: Do the various flavors of NOS support this ARCNET card

and how..I am using WNOS4 here and can recompile it with the
'ARCnet thru PACKET driver' defined but what next ???.

As you can see, I am fairly new at this.

At the moment I am running WNOS in the 286 box and WNOS4 in the PC to
talk to it which sort of defeat the purpose of having a cheap PC out
there, you will have to agree..

Hope you can help, 73 and bye

TAPR sells (or at least used to sell) a bare board for the classic TAPR TNC.
They also have the ROMS for several versions of software to run it. All you
gotta do is scare up the rest of the parts and put it together. You'd probably
be better off buying a used MFJ 1270/KPC-2 or 3/PK-88, tho.

The last time I checked, TAPR was almost out of the boards and almost certainly
is by now.  Unless one had a well-stocked junk box, getting the parts would be
quite difficult and most probably cost more than one of the mentioned TNCs.
The most popular use for these boards, I understand, was to build them up
without the modem as a front end for a TAPR or G3RUH 9600 bps modem.  TAPR  is
working on a a similar board without modem (TNC-95) for use with its DSP-93
(and presumably with other external modems), but that project has not been
completed.

Hi,

I've recently dug my Baycom modem (the little one built into a DB-25 hood) out and
hooked it back up to my computer. Does anyone have any info on programming it?  It
looks like L2.EXE handles all the I/O and it should be fairly simple write a new
front end for it. In particular, I'm thinking of writing a better BBS for it.

Is anyone using J-Com's SofTNC software with the BayPac packet modem?

Is it better than the BayCom V1.4 software included with the modem?

I'm using the BayPac/BayCom combo now with an HTX-202. Needless to say,
performance is less than ideal.

Should I buy Ramsey's SofTNC or should I just purchase a REAL TNC?

Any comments or experiences would be greatly appreciated.

What are the "best" (clearest, most complete, readable) books on
packet radio?

What opinions have you to offer on the "BayPac" module ($49.95) which
plugs into personal computers, avoiding the need for a TNC?  Other
than its limit of 1200 baud, what are its PRACTICAL disadvantages,
for packet work?

Any help you can offer will be appreciated ...  thanks in advance.

Everything you need to know about packet radio, can be learned in
3 days using a TNC.  It's also more fun that way.  Open the manual,
play with the parameters, and learn.

It sucks.  But some would rather spend 50 bucks and expect less, than
others who spend 100 bucks and expect more.

Basically the Baycom modem turns your computer into a serial port chip.
Rather than using a serial port (about 50 bucks for a dual 16550 board),
it uses software to simulate one.  Packet at 1200 bps would need at least
a 2400 bps sampling time to recover the data.  Thus your computer spends
all its time converting bits to bytes, and then the higher level protocols.

Only the feeble minded would use such a terrible device on a PC.  It would
be fine for a C-64 which otherwise would be in the dumpster...

I have an external 2400 bps modem that I don't use. I was wondering can I
use it as a TNC. Do you know how do I do it?

I've been looking for some contesting software for the KamPlus. I'm using
HostMaster II+ for general operations, and it's OK. However, while it has
a rather clumsy logging function, it won't dupe. That's not very good for
RTTY contests. KaGold can be made to dupe (by bringing up previous
contacts in the banner), but I don't like the fact that it won't display
the PacketCluster and HF contact at the same time. You have to switch back
and forth - that's no good. I understand that there is one or more
programs available specifically for RTTY contesting. I think perhaps WF1B
produces such a program. Any comments would be appreciated, including
sources for what I am looking for. Program must display HF and VHF on the
same screeen. It must include serial numbering and logging for contacts
and must dupe.

I need a list of popular 2M packet nodes in the Dallas area for a new ham
wanting to come up on packet.  If there is a central contact in the area
that can help new packet hams, that would also be appreciated.

I have a MFJ1278.  Mine only supports black and white fax.  Plus the
?4.?MHz clock drifts like a cheap watch.  I gave up on the MFJ and use
JVFAX (V6.0).  With a real(and I mean dirt cheap) converter you can
recieve very good true greyscale HF wx and press(kind of rare) FAX.
You can snag a copy of JVFAX from the oakland ftp ssimtel mirror.
If you bought your MFJ new, MFJ included some sort of FAX program.
If you want, I will take a look at my orignal MFJ disk and see what
they sent.(I was not real impressed and wrote my own special terminal
package for RTTY/ASCII(Yea real common) and Amtor.
The MFJ 1278 is a great RTTY/ASCII/Amtor ok CW and verrryy bad FAX and
SSTV decoder. JVFAX just stomps it into the mud.
VHF packet is good, but HF packet has some trouble in the crowded ham
subbands.

Better you buy another interface instead of 1278
It'is really poor because all soft I tried  has a very low resolution
To receive and trasmit fax in "professional mode" try the soft JVFAX
7.0 with a stupid UA741 based interface, and for trasmission direct
from the speaker of the PC. Support every VGA vesa extension and
receive and trasmit also color faxes and sstv.
I swear!!  Great...
Cost of  hardware... 5000 italian liras (less than 4 US bucks)
In packet and rtty Mfj1278 is still really good....

Probably not.  The best way to find them is to listen with your TNC and
log them.

I am a volunteer with a group that provides emergency and disaster
communications services.  We have a BBS (it's really much more than just a
BBS) running on a donated Sun-3 and the MTI-1600 serial card we have been
using seems to have bit the dust.  If we had the documentation we might be
able to diagnose and fix it; or maybe someone has another MTI-1600 they
aren't using?

If you have an MTI-1600 or equivalent (or even a terminal server :-) or
just documentation for the Systech MTI-1600 that you would be willing to donate
(I'll pay any shipping or photocopying costs).  We have a Sun-3/160, which is
a VME bus but we have a Multibus adaptor card we have been using with our
MTI-1600 (which failed).

Or if you know how to use the diagnostic mode on the card, even that might
be helpful.  While the machine is up and running, we have lost all our
connections which come thru this card, we have phone modems, radio modems,
and emergency information via satellite that is fed in thru this card
and we're stuck without this card working.  We were using 10 of the 16
RS-232 ports on the card.  Any help would be appreciated.

        I need some help.

        The problem involves the "Print This Channel" feature (function key
6) on Kantronics' HostMaster II+ (ver 3.11).  When this feature is
selected, the characters currently being displayed on the screen are also
to be printed on the local line printer.  The screen display is fine.  The
problem is that each character printed on the printer is echoed and a
carriage-return, line-feed is not added to the end of each line.  For
example, instead of "HAD" the pattern "HHAADD" is printed.  I'll leave the
example of the carriage-return, line-feed problem to your imagination.

        As a stop-gap, using the "Save to File" feature (function key 5)
and selecting PRN works just fine.  This scheme directs the data to the
printer, does not echo characters, and places a carriage-return, line-feed
on the end of each line.  While it this circumvention works, it is more
cumbersome.  But more important, why doesn't the "Print This Channel"
feature work properly?

        The printer is an Epson LQ-570.  Host is running DOS5.0/Windows3.1.

I check my packet bbs maybe once a month nowadays;  most of my email is
via internet now, and rightfully so.  Lots of other hams are even less
regular. It depends on the local enthusiasm for packet.
Invariably the several times i've sent email to locals via packet I've
asked them about it on voice weeks later and then they turn on their
systems and read their outdated mail.

You still use packet BBS's?  I gave up on them a long time ago. The only
mail I send/receive over packet is via SMTP, and it doesn't matter then
if it's another packet radio TCP/IP host or one on the Internet.

In at least in Southeast Michigan the packet BBS's are very very much
poorer than they were about 5 or 6 years ago. Back then we were trying
to figure out how to increase the speed of packet messages to their
destination. A few hours anywhere in the state and under 24 hours to
anywhere in the country was way too long. Right now it's very very common
to take a day or two for a message to travel about 75-100 miles within
the SE Michigan area. I still get people sending me message headers now
and then for personal mail that took a day or two just to go through
2 or 3 BBS's, while a bulletin will get through right away.  This is
the reason why a large portion of the 'old timers' on packet in my area
don't use BBS's anymore,  we see them as a failure in packet radio. Most
have gone to TCP/IP on packet and/or the Internet.

Well I use plain old kermit - it's quite clutzy but I can get it to do what
I want.  For X there's Seyon (comes with a lot of Linux distributions)
but I didn't like it very much as-is; it is definitely phone bbs oriented.
I talked to one guy who was developing a Tcl/tk packet terminal for X,
but I don't think he's done with it yet.  Other people I talked to about that
said just forget it, switch to TCP/IP and you'll never want to connect to
a PBBS again anyway.

I am the sysop of the N9QPI BBS and we have setup a tcp/ip mail delivery
system here in Southern Illinois.  I run F6FBB on the BBS and forward mail
for delivery to my personal JNOS station and then it forwards them to
people I deliver mail to.  I also send local mail to another JNOS station
so he can deliver to people on another Frequency.  We are developing a
nice mail deliver system here in our area.  People love it when they don't
have to go looking for their mail.

Over here, many BBSes run F6FBB and my version of NET together on a
single system using DESQview and one or more SCC cards.
This is a very convenient BBS system: it allows private mail forwarding
using either AX.25 or SMTP, and has FTP access to the BBS public file
area.
It also directly interconnects to the NET/ROM network as a node.
A single 386+ system with 4MB does the job.

OK guys, I've decided to take the plunge.  An avid HF'er for years, I gotta
take the plunge and find out why so many are intrigued w/ packet.  I have a
RS HTX-202 and 404 and am ready to hook up to a TNC(?).  I've read a few
articles and books, but the subject still appears confusing.

.as I understand it, the 1200 baud stuff is prevalent and availably cheap
(PK-88, KPC-3, etc), also referred to TNC-2.

I'd like not to spend over $100, but would also not like to throw anything
away should I get hooked and want to go 9600-19.2 (the 1200/2400 speeds
are not particularly exciting at first glance).  I recall reading
from a VE-ham that the KPC-3 is not expandable to faster speeds, for
example.  Please help out a confused, naiive, but fellow ham.  Models, good
stores, deals, kit, etc advice/offers are appreciated.  Get me into the

The most important thing you can do is *not* to ask here, but first ask
your local packet community what and were they operate. It may be fun to
jump fresh into packet with a 9600 TNC but no fun at all if you have the
only 9600 TNC.

Don't even think about 9600 on your HT's.

No, neither of those is a TNC-2, or clone of a TNC-2. The TNC-2 was
originally a TAPR design, and several companies make licensed clones,
but neither the AEA nor Kantronics designs are TNC-2 clones. The
MFJ-1270 and the PacComm Tiny 2 are TNC-2 clones. The advantage of
buying a clone is that third party hardware, like a 9600 baud modem,
or third party firmware, like TheNet, will work. They won't work in
a KPC-3 or PK-88.

Right, you either want one of the TNC-2 true clones, or something that
operates with the TAPR disconnect header (PK-232), or something from
Kantronics that *already* includes any modes you might want to use
later, such as the KPC-9612. However, be aware that your RS handhelds
will only operate properly at 1200 baud. They aren't designed to pass
9600 baud, in fact few voice radios are. For that you'll want a Tekk
data radio or a Kantronics D4-10, or (big bucks) the Azden PCS9600D.

For now, I'd suggest the Tiny 2 or a MFJ1270/1274. They'll work with
your radios at 1200 baud, and you can upgrade them to 9600 later
when you get a radio that can handle it. Or just buy a KPC-3 and
figure on replacing it too when you move up in speed. All of those
choices are going to be over your $100 budget, but only by $20 to
$30. You can probably find any of them used in the $60-$80 range.

JIm's advice is good. If you expect packet to be like the internet,
forget it at 1200 or 9600 baud. It's much too slow, and internet
style features and support generally aren't there. However, if you're
interested as more than a user, IE you're interested in the technical
aspects of data communications (hardware or software), then it can
be educational. But if you want internet style performance, you can
have it with more advanced systems (such as the WA4DSY 56kb RF modem
and TCP/IP software). *Then* you're talking ISDN level performance
and internet style services.

From an application perspective, I'd totally discount the BBS
world. It's a pale shadow of what we have here. However, there
are two *killer apps* that are useful at the low speeds. One
is Packetcluster. If you're a HF DXer, you can't afford to ignore
Packetcluster for DX spotting reports. The other killer app is
APRS. This is the geographical mapping and tracking program
that allows you to plot station positions automatically on a
map, either from GPS data or from hand entered position reports.
For certain public service activities, for RDF, and for navigation
experiments, this is a must have.

Bingo.  Between Jim and your advice, that's *exactly* what insight I was
looking for.  My expectations are now measured and focused.  Think I will
watch for opportunities of "closet TNC sales".  May even look into the way
cheapo get-your-feet-wet Baycom path...

Another thought on the "bash packet" vein:
I like point-to-point remote control and wireless data transfer (on non-traditional packet channels), which **some** packet
systems provide.  All or most TNC's support text transfers and I really enjoy Digicom-64 and Baycom's abilities to transfer
exe files painlessly between these systems.
Digicom-64 has an almost completely ignored and unused feature of I/O via the C64 user port that I dearly love to play
with, using it to control relays, synthesizer inputs up to 8 bits, etc, as well as being able to remotely program another
C= machine via the online ML monitor.
I also find Packet Radio to be EXTREMELY useful for emergency communications or covering remote events such as our local
church Girl's Wilderness Camp which is usually held in the boonies far from telephones and (so far) out of cellular range.
 Every time I've arranged for 2 or 3 in-town ops to monitor for traffic from the camp, it seems most of the time when the
camp calls in for more toilet paper, a girl lost her insulin, somebody's grandma died, etc, the town ops are eating dinner,
watching TV down the hall, or otherwise frustratingly away from the radio.
We tried using packet the last couple of years and it was great.  Instead of getting upset because my town station wasn't
able to respond quickly, I just connected to his TNC via packet and left the message, order, etc, in his data or mail
buffer, upon which invariably when he called back he'd already taken care of the traffic.  Neither end has to be "right
there" to effectively handle traffic.   With my portable Digicom-64 systems I could even set up alarms to alert the
operator that new traffic was there.
I don't hear much about packet use in such situations but I think it is one of the few things packet is actually
good/superior for.
But for what most hams fight to do with it.... sending and receiving online or email traffic that takes hours via packet
and seconds via internet...  packet is the pits.

This article presents a scheme that could improve the performances of
half-duplex network using digipeaters. Comments are welcome.

digipeaters
-----------
The simplest way to transmit packets across a network is using
digipeaters. A digipeater simply repeats a packet, some very limited
processing must be done by the digipeater. The overhead in network
traffic caused by the use of digipeaters is low in an error-free
environment.
The drawback of digipeaters is that there are not efficient in presence
of errors. Since the error control is done only at each end of the link,
timeouts must be set to a large value in order to account for the time
that the packet needs to cross the network, and the acknowledgement to
travel back. If the packet is not correctly received by the first
digipeater, the packet could be repeated immediately. But actually the
packet will be repeated only after the timeout has expired, so a lot of
dead time is wasted.
And if the packet succesfully crossed several digipeaters, but is lost
just before reaching the end node, the packet will have to be repeated
across the whole network again, even by the digipeaters it successfully
crossed before.
A improvement over a digipeater is a node.

nodes
-----
When a packet crosses a network consisting of nodes, 2 levels of
acknowledgements are used. The first level is between adjacent nodes.
The second level is between the two ends of the link. With 2 levels of
acknowledgements the above problems are eliminated. Nodes are more
efficient with the drawback of producing more traffic.

intelligent digipeater
----------------------
I have not heard of a scheme using the property of half-duplex
 networks, that is that only one radio frequency is shared.
So the following behaviour could be implemented:
after the packet is transmitted to the first digipeater, the
originating station can hear if the packet is retransmitted by the
digipeater to the next one. If it is not, it can assume the packet was
lost so it can repeat the packet immediately.
The same behaviour can be implemented when the first digipeater
is transmitting the packet to the second one. And so on, until the last
digipeater who must wait for an acknowledgement instead of a
retransmission.
This scheme keeps the network traffic low but should be more efficient
that a "dumb" digipeater.

Does anyone have experienced this scheme or is there something I didn't
think of ?

This may be true in general, but certainly not in this case.
The above examples are clearly cases of "doing it differently without
any good reason".

When you want to design a better system and have it accepted, it certainly
helps to make it easy to move from the old system to the new.  That is not
done by changing all the familiar commands.

That will certainly be a factor in acceptance, no matter how much you
(dis)like it.  Look at the number of users who won't switch to NOS
because they would have to learn all those commands.

That is not the way to do it, use a TCP/IP package instead.
(which uses the TNC in KISS mode, or better: an SCC card)

It works, but it requires an increase in speed by an order (or two) of
magnitude before it is seriously useable.  The NNTP protocol used by
newsreaders is very inefficient when compared to the standard BBS
user interface.

Once upon a time this was the case. Most modern UUCP's don't suffer
this brain damage.

Note that I was NOT proposing the use of UUCP. I was using UUCP as
an *example* of how store-and-forward e-mail can be made to work
within the framework of the Internet domain name space without being
directly connected to the Internet.

As long as people insist on running MS-DOS they are going to be
stuck with monolithic software such as MSYS. If you want modules, etc.,
it's already been done. It's called FreeBSD.

No. Re-read my original post. I never proposed UUCP. UUCP would be
a bad choice, in any event. I was simply using it as an example of
a store-and-forward network that worked with domain names in e-mail.

>In fact, I thought UUCP was
>a precursor to ftp even;

Probably. They are two completely different beasts, though. FTP is an
internet protocol for file transfer. It doesn't implement a network
or transport layer in and of itself. UUCP is a batch-oriented remote
job entry system. It does implement it's own network layer when running
over dialup or dedicated serial links.

That's the ultimate goal. However you aren't going to see wholesale
change overnight. This is why I proposed adopting a higher layer
protocol (SMTP) for e-mail. It can be made to run over AX.25 virtual
circuits just as well as over TCP. The issue is routing the mail. (Not
the packets - the mail.) SMTP would require us to adopt Internet
domain names for the existing BBS software. This is a Good Thing.
But you still need to figure out how mail to foo.ampr.org gets routed
when foo.ampr.org is an MSYS BBS not connected to the Internet. The
Internet side is easy - install an MX record pointing to the nearest
Internet-connected gateway. Where it gets interesting is when we
don't have the DNS to rely on for this information (such as the case
where the system in question is not connected to the Internet).

E.g.:

        ve7tcp.ampr.org -> ve7fg.ampr.org -> ve7duc.ampr.org

ve7tcp is Internet connected. ve7tcp talks to ve7fg via SMTP over
AX25. ve7fg talks to ve7duc via SMTP over AX25. Installing an MX
record for ve7duc pointing to ve7tcp takes care of getting the mail
*off* the Internet, but now ve7tcp has to figure out how to route
mail to ve7duc. The scenario above is *identical* to how the UUCP
network operates when faced with this sort of routing issue. The UUCP
sites fall back to pathalias and the UUCP maps. We would fall back to
pathalias and the AMPR maps. It's not an elegant solution, but it *works*.

I think you meant 'g'. 'G' is an SVR4 thing.

Both 'g' and 'G' support packet and window size negotiation. The
historical defaults for 'g' are 64/3. The protocol supports up to
1024/7, but coding bugs in the original implementation caused values
larger than the default to overrun an internal buffer, resulting in
SEGVs on many systems. (Increasing the window size almost always works.
Increasing the packet size can result in lossage.)

Many modern UNIX implementations will let you crank 'g' up to 1024/7.
A notable exception is SCO which pukes if sent anything other than
64/3, although it *will* negotiate (and use successfully) 64/7 in the
other direction. I'm running 'g' at 1024/7 (both ways) to a system
running BSD/OS 1.1 (running the UUNET derived UUCP implementation). It
easily maxes out the V.34+V.42bis modem link.

This is really getting off topic :-)

UUCP is pointless in this application. The reason UUCP implements error
correction is to get around errors from noisy phone lines. AX25 virtual
circuits *already* *provide* error correction and sequencing. Adding another
layer is redundent. Also, running a packet protocol on top of another
packet protocol will result in horrible throughput.

Running SMTP directly over an AX25 VC will work just fine.

 My wife and I are converting a school bus and moving aboard, taking her
sewing machine, my computer (486) and "our" new 2m Icom 2000H along.  I want
to get into packet, she into ragchewing, neither of us has our license yet
but we're studying.

I've been reading all the radio elecs books I can find but can't
really find (or understand) the answers to some problems I have
involving electrical systems- I really hope somebody can help me out!
        - I want to install a bank of deep- cycle batteries to power the
water system pressure pump, stereo and 2m rig.  Should I wire all the DC
power to the 2 poles of the batteries and have a special setup to
recharge the batteries?  The alternative seems to be to run all (-) lines to
 the chassis which would tie it into the auto electrics and (?) expose the
delicate devices to all sorts of surges and spikes and otherwise dirty power.
        - Since the computer's power supply puts out assorted voltages of
DC, could I not just transform the 12V battery bank juice into tightly
regulated power the PC wants and avoid having to wait for an AC hookup
to use my PC/ packet?  Would there be a problem having the 2m working on
battery and the computer running off (possibly ungrounded) AC?
        - Let's say I can find a 12V motor suitable to run my wife's sewing
machine and replace the 110AC motor it has with that.  Would there be any
problems/ what problems would there be running computer and sewing mach.
at once, assuming I have a bank of batteries with enough amp hours to
cover the total draw?
        - Would a better idea be to just get a massive inverter and a
humongous battery bank and run everything off AC?  Anybody got a spare $1750?

I hope somebody can drop us a line; we have to move aboard by Jan '96 and
would like to have a few amenities in place
        Thanks loads in advance-

There is 1.18 as well as the update to 1.19, which requires 1.18.

Hi Ken!

This is the best URL for the most recent MSYS versions:

ftp://coffman.csuohio.edu/

You'll find version 1.19 as an ".exe" self-extracting archive on there...

I am looking for advice on building a digital filter.  I have a
real-time 16-bit audio stream, generated by sampling at 16kHz,
that I need to have high-pass filtered to eliminate PL tones.
The filtering is part of a custom repeater controller I'm running
on a Sun Sparcstation 10, so I have plenty of CPU available to run
the filter code.  Years ago someone showed me a "recursive" digital
filter which was extremely simple, replacing each audio sample by
a weighting of the previous two samples (the weights determined the
filter cutoff).  Unfortunately I don't remember the details.  Can
anyone provide help, or at least some references to books or papers?

Hello, The Michigan Technological University Radio Club is looking for
some info on how to do a hardware reset on a RC-1000 repeater controller.
Our problem is that our processer is not recognizing any of the "D"
commands.  The system is reading back all the dtmf digits using the
readback function which tells me that the decoder is functioning properly.
It will also accept the D7b and d7c programming codes properly but not any
others.  Perhaps this could be because the code that our manual says is
supposed to come up D62 for the program code is not right?!  If anyone has
any answers I'd pay to hear them, otherwise I'll be forced to trash this
controller.  I've tried calling M.C.C. and they are out of business.
                                        Thank You,
                                        Rob Hall AA8LA

One approach (the one I happen to be pursuing myself) is to use Linux with
the AX.25 extensions added to the kernel.  Among other things, this allows
you to connect a KISS TNC as a SLIP device bound to a pseudo-TTY.  Once
done, the TNC looks like just another interface device through which to
pass TCP/IP packets.  Routing, configuring gateways, etc. is then performed
using the standard UNIX facilities.

The "official" list of packet/Internet gateways can be found at:

        ftp://minnie.cs.adfa.oz.au/hamradio/gateways/resource

The hosts on this list are running a wide variety of different kinds of
gateways, e.g. TCP/IP, mail, encapsulated IP, encapsulated AX.25, conversd,
and so forth.

I am also using 1.00A and it works fine for me. At the risk of being
deemed a "Luddite", I did not care for the second version very much.
Also, since I do not have the PK-232 MBX model, I could not use the
Pakratt for Windows version and can't comment on it.

Keyboards like that exist, but they use an Infrared link (like your TV
remote), not an RF link.   Infrared is cheaper for this purpose.

Modern modems have builtin processors that make it difficult to run
standard (HDLC) packet on them.  You could devise your own protocol, but
even in that case you will have to provide a "transceiver to phoneline"
interface (because the modem expects to see a phoneline).

This will be so much fuss to make, that is is easier to make a 1200 baud
modem from scratch.

      Hello, my name is Mike and I am in search of a Motorola
Saber 3 radio. As much as I would love to have a "secure" Saber
my HAM lic can live with only a "clear" version. 440-470 stock
pkg is fine.
      Sounds easy enough, save for this one small caviot, it
must, must, have it's Serial Number tag visible and in good
condition on the back of the radio. Here in Brooklyn North the
police often "detain you for varification of ownership" of
your radio if the SN# tag is not in place. I have a wonderfull
Saber 3 that I bought at a HAM fest but it lacks the desired SN#.
       So if for some reason money sounds better to you then
owning a Saber 3 clear uhf 5 watt radio then e-mail me fast

Hi Paul,
You're right there is a difference in pitch.  This is probably due to the fact
that the crystals involved are not at an equal offset from the I.F..  Is this
a problem?  Probably not as long as the desired sideband is centered in the
filter and not unduly attenuated.  Should you try to fix it?  Probably not!

That's one approach. However the RFCs deal mostly with services
on a fully connected network with high bandwidth and low loss
rates. What we have on amateur radio is almost the exact opposite.
Our networks aren't fully connected, or operational 100% of the
time, our effective data bandwidth is typically very limited,
and the loss rates on our shared channels are typically very
high.

Now we can attack the problem by trying to create a RF network
with full connectivity, 100% uptime, high data bandwidth, and
low loss rate, or we can attempt to develop protocols that work
under the conditions in which we actually operate.

I think there is merit in both approaches. While we can certainly
improve the hardware underpinning of our packet networks, I don't
think we're likely to approach the level of the internet in regard
to connectivity and low loss rates with high throughput over large
geographic areas. So, I think that work on protocols better suited
to the networking environment we face is appropriate.

Gary

Unless the network is collisionless and error-free, which can nearly be
achieved by the use of a central realtime repeater system in each LAN.
Then maxframe is really not important.

It's clear to me that local uncontrolled station access should be by
means of a LAN repeater, and that links between LANs should be unshared
and preferrably full-duplex.

This requires a bit more equipment and some degree of planning.

Hello all, and thanks for reading this.

I have a KPC-3 with the upgraded 128k memory chip installed. Im about to
get a Kantronics 9612, and am wondering if I can use the same chip that is
in the KPC-3, in the 9612.

Anyone know if it is the same part number for both TNCs? I tried all the
candy stores around, and short of calling Kantronics (long distance),
thought Id ask here first.

Thanks again...and GO BUCKS!

Yes!

I think what you are looking for is a MOO, a Multi User Dimension Object
Oriented.  It works a lot like Packet Cluster.  You have nodes that are
linked via the Internet and everybody goes in a node via 1200- or
9600-baud packet.  It looks like spokes on a wheel and all the centers
are connected with on another.  A group out of San Francisco State gave
me a demonstration at the recent Pacificon '95 in Concord CA and I was
really impressed.  Here's some Web address to find out more:

You need a negative supply voltage for a 7905. The poster wanted to go
from +12 to -5. Maxim and Linear Devices (or is it Linear Tech? data
books at work...) make such things. Typically an 8-pin DIP, requires
an external cap and inductor, can do 100mA easily. Maxim is very good
about sending out spec sheets, application notes, and free samples.

Oh yeah, sure.  At the current throughput of most packet channels, it
would take most of the morning to paint the ARRL logo on your screen.
I can just see people browsing around at that speed.

Jeez, it would be faster to chip it into a stone tablet and tape it
to a duck that waddles from one node to the next.  Get real.

Yes, it is the same chip.  A generic 128K x 8 low-power SRAM.  The only
possible difference is that the CPU clock rate in the 9612 is 12.2 MHz,
but the KPC-3 runs 7.3 MHz.  This probably means the RAM cycles
require faster access time.  Most likely a 100 ns RAM (that is about the
slowest you can buy) is plenty fast for either though.

It isn't unfortunately. The C64 (and Vic20/Plus 4 for that matter I
think) implement a kind of pseudo RS232 at TTL voltages. Therefore you
need TTL/RS232 conversion circuitry. This can be done simply and well by
the use of Charge Pump ICs such as the MAX232, or more cheaply using the
circuitry used in the simple Baycom modem. In fact, if the C64 (Digicomm)
modem uses a TCM3105 modem IC, it may be easier and neater just to buy or
make one of the simple Baycom modem boards and to move the TCM3105 over
to this new board.

Hello All, A few of us here at the University of Maine have the DJ160T
handhelds.  We would like to connect them to packet radio via the baycom
software and hardware.  However, the connections that listed in the
.doc file do not work for the radios. Has anyone had any experience
with connecting the 160's  to the baycom units?
Any help is appreciated.

"Why a duck?" -- Chico Marx

OTOH, the authors of that article were quite explicit in saying they
were using 9600-bit/s links. And those fortunate enough to have a
56 kbit/s network in their area would find HTTP over the network
quite acceptable. Who knows, maybe this kind of technology will
encourage the growth of faster packet networks.
