Hi net-ers.
Do you know any source for the TMC3105 chip ?
(I mean that they have it in stock)
I prefer a source in USA.
I checked with Marsal Electronics.. They need 16-23 for stocking.
I will appreciated e-mail answer.

I've run into problems upgrading the firmware in my MFJ 1270B
TNC from TAPR 1.17b to 1.18.  When I power up the TNC with
the 1.18 code, the STA and CON LEDs light and stay lit. The TNC
locks up immediately without displaying any information on the
terminal.
Has anyone experienced difficulties running the TAPR 1.18 code
on their MFJ 1270B.

I'm trying to decide whether I should spend the money on a multimode

Anyway, could anyone tell me what differences there are between
AEA's PK-232MBX, the MFJ-1278 and Kantronics' KAM?

I'm still a newcomer to all this, so sorry if it's a dumb question.

Subject: AT-based terminal server?
To: [e-mail]

I've been looking over the KA9Q package for using IBM-PC-style
platforms for network routing, mail, etc.  It occurs to me that one
thing that seems to be missing is the ability to run a telnet session
over a serial port, i.e. dialing in to a PC-AT from a remote site with generic
telecommunications software and getting a "telnet>" prompt, and then
being able to connect to other hosts.

I'd be interested in finding any software which accomplishes this.
Basically it would support 1-n serial ports and one Ethernet or other
network port (perhaps just another serial port running PPP or SLIP).
If nothing else, KA9Q can probably be modified to provide this
functionality, but I'd rather not duplicate effort if at all possible.

Can anyone provide me with any info?  Thanks in advance.

To: [e-mail]

I'm working on it. Or more specifically, I'm working on the basic mechanisms
that would allow this service to be provided without a lot of ad-hockery.

Recently I've reimplemented the stdio (standard I/O) package as part
of NOS. (Previously I had been using the stdio library provided as
part of the regular Borland C++ library). The new stdio library allows
you to use file stream functions (i.e., functions that operate on FILE
* pointers) on network sockets, internal inter-thread pipes and the
new terminal emulator. I will probably add support for serial ports
fairly soon.

This means that pretty soon the various NOS commands can run pretty
much without change on the local console, TCP connections or serial
lines.  And something like a telnet server (or modem server, which is
really the inverse function) should then be pretty easy to implement.

Watch the code in ucsd.edu:/hamradio/packet/tcpip/ka9q. I'm updating
it on a regular basis, but since it's work in progress you should use
it at your own risk until I announce that it's stabilizing.

Subject: Packet

  I just picked up a MFJ-1270B, and now I want to connect it to my
Alinco DJ-160 hand-held.  The manual has five wires coming out of the TNC,
and I have two points of connection on the HT:  one little port for an
external speaker, and one for an external microphone.  Now, I can pretty
well figure out where, from the TNC, Microphone Audio, and Receive Audio
should be connected.  But I've also got Ground, Push-to-Talk, and Squelch
Input (which is described as optional). I can see that Ground might just
need to be connected to the base part of the plug wires, but where will
Push-to_Talk go?  On the same wire as Microphone Audio?
  If any of you have done this before (how five wires are connected to
two plugs), I'd appreciate hearing about it.
  Tnx and '73,

Subject: Re: Packet

Larry, the PPT line or "mic" input is the same as the "AFSK" input to your
TNC, the audio output on your HT is obviously the audio input to your TNC.

I am not very familiar with Alinco Products, but MOST HT's require isolating
the ground in the AFSK input. Usually the TIP of the connector is the AFSK
output, and the "ring" is the ground for the PPT. Typically using a .1 MFD
capacitor and approximately a 27K Ohm resistor in series is the interface
you'll need to use. Here's a schematic....

TNC                     HT
AFSK------------(.1 MFD)-------|
                   |
PPT--------------~~27K~~-------|--------Tip of Mic Plug

The audio circuit is probably strait forward enough to leave out of this
explaination. (Oh...if you find your "deviation is too high...that is
the audio level transmitted it to much, increase the size of the resistor, and
if its too low to be heard, decrease the size of the resistor.)

If you carefully pick the physical size of the cap and resistor, you can
easily fit them inside a minature phone plug.

Good luck, 73, Bill/KI4QJ usr3235a
----------------------------------------

The next question:

Is a similar procedure also necessary to connect an AEA PCB-88
to a Yaesu FT-411?

I have to run up to Rat Shack to get the miniplug anyway, so do I
also need to get the .1 microfahrad capacitor and the 27Kohm resistor
and the .1MFD cap goes on the bottom contact of the sub-mini and
the 27Kohm resistor on the tip contact?

    HOW TO ACCESS THE WB3FFV AMATEUR RADIO TELEPHONE BBS !!!


 I have placed a BBS system on-line that is mainly oriented towards the
Amateur Community (but there is other stuff on-line). As of now I have not
attempted to promote this system any place except in the amateur channels
(PACKET, USENET, & word of mouth), and will continue under this policy, as
I hope to keep it oriented toward amateur radio. The various software for
UP/DOWNload is available via telephone dialup and Packet TCP/IP, and through
user support I hope to keep the latest and greatest ham software on-line.
Below is the information that is needed in order to access the BBS via
Telephone -or- TCP/IP, please pass it around to as many ham's as possible.

 System Name: WB3FFV
 User Login: bbs

 Number: (410)-661-2475 -- 1200,2400,4800,9600,19200,38400
               (V.32/V.42/V.42bis/MNP1-5)

               (V.32/V.32bis/V.42/V.42bis/MNP1-5/HST)

 Number: (410)-661-2648 -- 1200 & 2400 (MNP1-5/V.42bis), 9600 & 19200 (PEP)

 Data Settings: 8 Bits, NO Parity, 1 Stop Bit
 Times: 24hrs/365days  (except for routine maintenance)
 Software: XBBS  (UNIX/Xenix Multiuser BBS) Version 7.91u
 IP Address: 44.60.128.1 {wb3ffv.ampr.org} [for FTP transfer via PACKET ONLY!!]
 Misc. Info: Machine is an 80486 computer running UNIX V.3.2 and features more
         than 1.5 Gigabytes of on-line file storage.
         Most transfer protocols are available!!


 I attempt to keep the latest and greatest HAM software on-line, and encourage
all to upload anything new that they come up with, as it is of benefit to all.
Here is a sample of a couple pieces of software that is available for DOWNLOAD:

 KA9Q TCP/IP Software for the PC (Latest OFFICIAL release + TEST Versions)
 KA9Q TCP/IP for the Atari-ST, MAC, & Amiga
 KA9Q TCP/IP for UNIX based systems
 KA9Q TCP/IP (The NOS release)  [UNIX, MS/DOS, Amiga]
 KA9Q TCP/IP (Version by G1EMM, PE1CHL, PA0GRI, Etc.)
 N2GTE Packet Message Switch [GTEPMS] (Version 1.2 & 1.3)
 WA7MBL BBS for the PC (Versions 3.31, 4.31 & 5.1[2,3,4])
 W0RLI BBS for the PC (Versions 10.xx, 11.xx, 12.xx, 13.xx)
 MSYS BBS for the PC running KISS TNC's  (Version 1.07-1.11)
 AA4RE BBS for the PC (Version 2.11)
 F6FBB BBS for the PC (Version 5.14 & Updates)
 G8BPQ PC-Node (Version 4.05)
 Various BBS utilities and enhancements
 Several MORSE CODE Tutors
 TheNet software by NORD><LINK  (Version 1.01 1.16 & 2.06, 2.08)
 Modifications for many HAM Rigs and Scanners
 Digital Signal Processing software (DSP)
 DX and contesting programs
 ARRL Newsletters & Gateway
 W5YI Electronic Edition

 There is much more available on the BBS, and I don't want to waste a lot of
PACKET BBS space trying to list it all, so if you are interested give it a
call and see for yourself !!!

If you are interested in using UUCP to connect to the BBS, this can also be
done as I support Anon-uucp. The login to the system is 'uucpanon', and there
is NO password. The listing of avalible archives are stored in a file called
'FILES', and it is located in the /usr/spool/uucppublic. To retrieve the files
listing just use the following command:

uucp wb3ffv!~/FILES /usr/spool/uucppublic

This will move a copy of my files listing into your uucppublic directory.  If
you have any questions or problems, feel free to contact me at one of the
numbers/adresses below. Good Luck...

I recently aquired a PMR rig for 2m conversion, which I have now
converted. I am planning to get my RAE in December, but I want to
use the rig now since I've got it working. Is it possible to
'listen' to packet. If so, I'll need a TNC, which one should I buy.
What's the frequency of packet on 2m, is it 144.650Mhz?

Answers to my questions would be greatly appreciated.

Thanks,

Andy.

I've argued for years that the To field should be used to designate subject
areas, and the @ field for geographical distribution areas.  I'm not
convinced that organization names like AMSAT need to appear in either field.
I wrote an article on the subject for Gateway several years ago, and there
has been some minor improvement since then, most notably in reducing the
proportion of bulletins addressed to ALL in the To field (Roy's BBS code has
helped in that regard... do any other BBS programs attempt to dissuade users
from sending bulletins to ALL?).  I'm not optimistic that things will get
much better in the PBBS network anarchy... that's why some people are
implementing Usenet-like news systems as an alternative.

It's too bad that no group (such as the ARRL Digital Committee, perhaps?)
has taken the bull by the horns and tried to set some standards for the
way mail and bulletins should be handled in the PBBS network.  Practical
experience should precede the setting of standards, but by now we've had
plenty of experience...

There may be cases where one BBS would want only AMSAT stuff, whilst another
might want only ARRL bulletins.  True, the subject should be more informative,
but no two people can decide on a standard subject format, it seems.  Also,
parsing the ARLxxxx is harder than @ARRL.

Has anybody ever suggested that the packet BBSes be replaced with
Netnews software instead of slowly but surely reinventing it from
scratch, with much pain and anguish along the way?

Never mind. I couldn't control myself. Sorry.

    Mine did the SAME thing. I purchased it at the SW Division Convention,
but have not yet called TAPR. Mainly because it's been so long that I was
sure they would question the handling. BUT! Since I'm not the ONLY one....

Bill, I've been running the 1.1.8 release firmware in a MFJ-1270B off and
on for a few weeks and it seems to work just fine.  Sounds like you have a
bad Eprom.  Did you buy it from TAPR or burn your own like I did?  I got
the firmware binary stuff from HamNet on Compuserve.

  Hello,

I have two MFJ-1270B TNC's and downloaded the 1.1.8 firmware from a bbs
system (I don't remember where), and then burned my own ROM's for my TNC's.
Anyway the short of the story is that they both worked fine, so it must be
possible to make them work.  You may have a bad ROM, or maybe somthing
shanged at some revision level in the MFJ.  My MFJ's both have 32K RAM, if
that makes any difference (I believe it is required for 1.1.8)

To: [e-mail]

Don't feel too bad, I was asking this same question last year.  I bought
the KAM, partially because of recommendations by other users, and
partially because Kantronics had a sponsored a seminar on digital radio.

On the "VHF" port, you can have several distinct packet connections at
the same time (one RF frequency).  You can also operate on the "HF port"
in RTTY or AMTOR at the same time as the "VHF" connections.  For
example, if you were into DXing on RTTY, you could use the KAM to
connect to the DX cluster for spotting while operating RTTY on the HF
bands.  I don't think the PK-232 will do this.

To keep things fair, on AMTOR, I 3 or 4 hams running the 232 for
everyone I contact using a KAM.

  A few weeks ago, while explaining the current amateur BBS arrangement
to a non-ham Unix developer friend, I made the observation that the
amateur community could do itself a big favor by ceasing to insist on
re-inventing a particularly painful wheel such as netnews.

  So, Phil, yes, I've suggested so. Of course, we know how must packeteers
will react.... rather than do something useful, they prefer to put up
another digipeater.

Interesting. I have found that it depends entirely on the current conditions
and your specific situation (proximity to an hf gateway mostly). I have
seen transcontinental messages delivered within a few hours. I used to
regularly receive mail in Atlanta delivered from New York in 5 to 6 hours.
The path was amazing - it almost always made its way from New York down
to Maryland, then down to Miami on hf, back to South Carolina also on
hf, then vhf terrestrial down to Atlanta. And in only a few hours. It
is truly amazing to see...

Lots of people have suggested it.  The packet BBS network does a reasonable
job of moving mail and bulletins around, but as a Usenet-type conferencing
tool, it's a dud.  No amount of tinkering will make a silk purse out of it.

On the other hand, it's too facile to simply say "replace it with Netnews".
I'd love to, but it ain't that simple!  Let's see some practical suggestions
on how to implement such a thing in the packet radio environment...

Yes, NOS has some NNTP capabilities.  Yes, it's now possible to run Unix
on your 386 box for next to nothing.  Yes, Brian Kantor and others are
looking into implementation of a broadcast protocol for efficient news
distribution to packet users.  And so on...  But it's not clear to me how
we could start implementing a packet Netnews network *today* that would be
accessible to all packet users.

Enlightenment, anyone?

The main reason is far simpler.  The typical packet user (who probably
has enough trouble at the DOS prompt) can not cope with the extensive
commands and options offered by netnews.

I run a land line BBS and know this from experience.

And conversely, those of us accustomed to netnews can't cope with the
limited commands and just plain weird conventions of PBBSs!

For instance, why on earth will a PBBS accept "B" and "L", but not the
full commands those letters abbreviate (BYE and LIST, respectively)?
Aargh!!

And in the listing of available bulletins and personal messages, why is
the destination BBS after the *sender's* callsign instead of after the
recipient's callsign?  E.g., if I send a message to KA9Q @ K3MC, it
shows up in the listing as "To KA9Q" "From N6BIS" "@K3MC".

Not to mention (okay, I'm going to anyway) the utterly delightful
inability to break out of reading a message once it's started spewing
onto your screen.

Oh well, if that's what BBS and PBBS users prefer--chacun a son gout.

You are painting all packet BBS prorgams with a broad brush.  I think
you will find most of the programs overcome the objections you raise.
I know mine does.

To many of the others that comment that packet BBS should do this and
that:  I make my source code freely available.  Please add your ideas
to the program and ship the modifications back to me for incorporation
into the master copy.  Over the years I have received five or six such
contributions.  Everyone of them is in the code today.

I don't think there is a good *standard* portable packet terminal.
Try asking on rec.radio.amateur.packet.

BTW, this newsgroup was supposed to be closed over a year ago, but it
still lingers.  The new amateur radio groups are rec.radio.amateur.misc

Hi, Roy.

Over the years, I have used 3-4 different PBBSs in the Bay Area
(Peninsula and South Bay). All of them have had the drawbacks I described.

Perhaps they all use the same software (W0RLI?). If your program is
better, I certainly hope that more sysops will switch to it.

p.s. If there's someone in the Sunnyvale area using your software
(I can't work as far as Gilroy), please tell me the callsign and
frequency and I'll gladly try it.

Subject: TAPR TNC-2
To: [e-mail]

Being rather cheap, and enjoying endless hours of tedium checking
parts of lists, soldering, and clipping leads, I have undertaken
to assemble a *real* TAPR TNC-2 from the excellent blank board
supplied by TAPR, and by scrounging parts wherever I can.   Unless
your junkbox runs to 20-turn trimpots and CMOS EPROMS, this is not
the way to save money, but its fairly educational and with luck
I'll break even with the cost of buying a store-boughten TNC.
My question to the world is: TAPR sells an XR2111 replacement for
carrier detect that they say does wonders.  Is it in fact a worthwhile
addition to the TNC 2 ?  Any particular pitfalls in the orignal TNC
that I should watch for ?  Should my next order to TAPR be for the
KISS software ?
  I started off assembling the K9NG kit but after two months,
there's still no-one out there to talk to on 2 metres; all the
9600 in this area is on UHF. I *still* think I can do it on 2, though.

Subject: Anyone using a KPC-2400 ?
To: [e-mail]

Greetings,

After a productive morning at the local hamfest I am now the proud owner of a
2M packet station.  I picked up a Wilson WE-800 2M FM rig and a Kantronics
KPC-2400 TNC for $160.

I would like to correspond with anyone currently using the KPC-2400 for packet
radio.  Having scanned through the manual once or twice now it appears that I
may have the front end of a packet bbs system.  Is anyone using the KPC for
this?  If so, what sort of computer and what software are you using?  Are there
any do's and don'ts that I should be sensitive to?

As I just passed my Tech exam on May 9th I suspect that I have several weeks
yet to work things out.

The TAPR 2211 DCD mod is indeed useful.  It's easy to install; you just
plug it between the 2211 chip and its socket, and chop out a resistor
on the mainboard.  What it does is allow you to run with an unsquelched
radio, which will greatly improve your receive carrier detect time.  It
also reduces chatter of DCD on marginal signals.  A good deal for $20.

It is legal, and if you call AEA they will treat you much better
if you tell them you're commercial.  They have a device called a
PK90 which is essentially a PK88 with a 2400 baud modem, and even
encryption.  They recommend Maxon (nothing fancy) commercial radios
and the interface is similar to hooking up any other TNC.

There are also fancier commercial packet companies out there as well.
Some even mention the protocol as AX.25.

  Thanks for your reply Ron.  I also have done quite a bit of checking
around and have also been told the same, packet is legal commerically.
As well as being able to encrypt the data commerically, I'm also told
that some commercial version packet controller are the same as the AX.25
unit that the ham radio operators are running, but just as odd baud
rates so that the standard AX.25 controllers can't monitor them.

At a hamfest yesterday I picked up a Heathkit HK-21 Pocket Packet at
a good price. Unfortunately, it came with no instructions, accessories (?)
etc.

I called Heath and ordered a manual, but it will not be here for a week.

Some of the connections are self-explanatory, but others are not.  Can
anyone give me a quick explanation of the connectors, how to set the
baud rate, etc. So that I can try to get it up before the manual gets
here?  (I'm going on vacation at the end of the week, and it sure would
be nice to take it along with me, but I don't think that the manual will
make it here by then.)

BTW, I assume that there is an external charger for the ni-cad battery?

This is my half-penny's worth on the topic.

Here in the Cleveland Metropolitan area, 145.03 was originally a 'real time' qs
o frequency by informal concensus.  It has 'almost' remained that way except fo
r the existance of one major bbs, which was infact the sponsor of the realtime
qso frequency.  This frequency still ramains one the main, if not the main, rea
l time qso freq.  Besides the main bbs there are a host of other personal mailb
oxes that beacon on the frequency, but they are essentially low use.

One of my concerns about the activity on packet is the proliferation of the maj
or bbs's on a single frequency. At first glance one wonders if there could not
be some enhanced coordination (without bureaucrary) so that there would be a na
tional bbs, a regional, and a metropolitan.  This would hopefully reduce some o
f the traffic and free up the airwaves for more packet activity.

On the other hand, maybe all of this is superflous!  THIS IS A HOBBY!

I've tried both.  Pound for pound, 2 meters is better for 9600 than
UHF, as well as not having radar problems like 70cm.  However, with
the TEKK radios being plug and play, and only the (terrible) DVR 2-2
being plug and play on 2 meters, most activity is on 70cm.

When we formed GRAPES, one of the first things we addressed was the
coordination of LANS. Actually they are MANS, but the name has stuck.
Anyway, we quickly decided that users didn't belong on the trunk frequency
playing BBS DXer. It caused unbelievable congestion that held off some
sites for minutes at a time while providing little throughput.

What we did was divide the state into RF regions called LANS. These weren't
simple lines on a map because of terrain. Basically we told users to choose
*one* LAN where they wanted to be found and *stay* there. GRAPES would
provide gateways to allow access to other users. Each LAN group has a
designated mail forwarding BBS that is accessable on the LAN frequency
and that has a second port on the trunk frequency. This keeps BBS to BBS
forwarding activity out of sight of the users. With proper mail routing
and near global bulletin distribution, there is no need for BBS DXing.

Each LAN also has a gateway switch with ports on the LAN and on the
high speed trunk. Any user can access any other user for keyboard chatting
via the gateways. The 56 kb trunk has the capacity, lacking at user
speeds, to allow simultaneous BBS to BBS traffic and user chats.

This is a very structured network and can be damaged by users not
playing by the rules. It is very effective, however, as long as
we can keep the gateways operating. The bane of the network engineer
is the packet DXer hopping from channel to channel around the network
looking for the furtherest point he can reach. This disrupts the
automatic routing algorithms and can cause unexpected congestion in
parts of the system.

I see a (somewhat) common thread.  Dos, amiga and (even) atari boxes have some
form of uucp based netnews software.  these packages accept compressed
news batches and uux files to tell the system what to do with the batches.
it would be a "simple" matter to replace a uucico with "yet another
protocol" to send and recieve data over a basic TNC.

Even though some might complain that sending the information
point-to-point via a broadcast medium is inefficent (it is!) I think
the experiment is worth trying.

Isn't the common uucico replacement NNTP in the Internet community? I believe
that the NNTP sources have been used on other then u*ix OS's, and also recall
a version written in perl (perl is available on DOS, amiga and others).

  Not to argue with the Brian's discussion I would pick the nit that it
is *current* vhf amateur packet radio which is inherently a broadcast
medium.  We simply aren't able to use antennas large and directive
enough to effectively be point-point in this portion of the spectrum.
This situation is likely to predominate for some time.  In that context
I have no disagreement with Brian's position.

  However, I (for one) live in hope that the broadcast nature of the
lower bands may be eventually be supplemented with microwave and
millimeter hardware which doesn't carry the broadcast/omni penalty.

  Radio *is* inherently divergent barring some guiding structure.  It
will probably not ever allow the kinds of (terrestrial) information
transfer efficiency of low loss guided structures that, say, fiber can
but we shouldn't rule out the possibility of eventually having some
relatively non-broadcast physical layer hardware.  The information
capacity advantage of this kind of channel is enormous compared to
existing broadcast channels.

  In the interim, I agree that it is extremely wasteful of resources to
continue as we are.  Within the forseeable future it will no doubt be
that the user links will be continue to be broadcast or semi-broadcast.
Even the Hubmaster stuff we are working on has antennas with
omnidirectionality in azimuth.  Dedicated point-point user hardware
isn't likely to be widespread anytime soon.  I think I can count on one
hand the number of multi-Mbps systems which are actually running as a
result of n6rce's and my article.  I expect that small shared
clusters/cells of semi-omni users are more probable than "stars" of full
pt-pt users.  By the time that most installations will have coordinated
two ends with highly directive structures they probably will have been
able to find a guided-wave alternative which is cheaper than radio and
has even more capacity.  In the end, the advantage of radio is the
lesser degree of coordination/connection it allows.  When it becomes
more difficult/expensive to use than "plug-in" access it won't be
attractive.

  However, if we totally write off radio as being broadcast only I doubt
that amateur radio stands much of a chance of continuing long into the
information age.

In the Netherlands we some use higher packet speeds then 1200 baud on the
same frequentions as used by 1200 Baud packet. The TAPR 2211 DCD doesn't
detect those transmisions and the result are colisions! So use them with
care and transmit only when a noise squels says the channel is free.
When the big users of a packetchannel go to higher transmission speed
between them, the packet channel transmission time goes down and creates more
transport bandwith on a packet channel for the 1200 Baud users.

Henk, PA0HZP

Ps: I like to see a DCD detect circuit which detect also higher packet speeds
with a short carier detect time? Current I am using a fast noise squels.

Subject : Re: Packet BBS distributions

At the simplest level, most mail and news systems just transport a file
from machine A to machine B, then use the file as input to a program run
on the remote machine.  UUCP's remote execution capability was (and is)
used for this purpose in uucp-based news and mail transfer.

In the ham BBS world, the file is sent by imitating a human user typing
over an open connection, with a slightly-formalized message structure.
What to do with the message is specified by the first line of the file
to be sent.

NNTP and SMTP (the internet news and mail protocols) use a dedicated
socket to feed the data over, so it's not necessary to have to specify
what to do with the data - the socket chosen implies what the file is
for, so dedicated programs can handle them.

Thus ANY file transport mechanism can be used to carry news and mail.
However, the current Ham BBS method is too crude for really flexible
handling as Usenet does; it would have to change a bit.  But there's
no reason why the command line, instead of being 'SB .....' to transfer
a message, couldn't instead be 'RNEWS messageid' and go from there.

But that begs the entire question of environment: radio is inherently
a broadcast medium.  It's silly and inefficient to keep sending the same
message individually to each person who wants to read it.  That
inefficiency was why we invented NNTP to replace Internet mailing
lists.  We should find a way for a broadcast technology to replace ham
BBSs.

The cheapest is to get a TNC-2 or clone and an old mobile 2m rig used.
Build your own 2m ground plane (plans are ubiquitous).  Even so, this
is probalby the cheapest even if you don't use used equipment.
TNC-2's go under a variety of names such as AEA PK-88, ...

To get started on packet you need a technician class license.  The
hardest part is the 6-8 week wait after you pass the exam.  :-(
Don't let it get you it has been that way for decades.

For gear, you can use almost any 2 meter FM transceiver, either an HT or
a "mobile".  For the antenna, start with a 1/4 wave groundplane mounted
outside, so it is away from any RFI generated by the computer.

Just about any computer with a serial port and terminal emulator program
can be used.  Later, you might want to use one of the fancy programs
meant for packet, but if you already have a computer and program to run
a modem for telephone, that can get you started.

Then the TNC.  New ones are about $130.  MFJ, AEA, Kantronics, and TAPR
are popular brands.  Actually TAPR is the amateur group in Tuscon AZ
which designed the first really usable TNC.  The others are clones of
TAPR's design.

Lastly, you need cables to connect all of these.  If you are not afraid
of soldering, these are not to difficult.  The hardest part is finding
the pin-out pictures for your particular TNC and radio and matching up
the info in from the different manufacturers.

73, and good luck on your exam.

Recently, John KB8GYS asked how long it takes to deliver a packet
message via NTS.  He and I conducted an experiment.  John sent me two
messages, one to my home BBS, and another via NTS.

The direct packet message was orginated on 05 June at 0357, and arrived
on my BBS on 9 June at 0149.  Which is 3 days and 22 hours.

The packet message sent to NTS took 5 days.  John sent it the same time
as the first message. It arrived in Freemont, CA the next day.  That is
~25 miles from my home.  Because of some problem in routing tables, it
went back and forth between two different BBSs.  On the 8th of June it
got to the BBS that is designated for my zip code. Finally at 0300 on 10
June, I got a phone call from the asst. sysop to "deliver" the message.
He and I chatted about the strange path.

Meanwhile, Bill G3RXS in the north of England also sent a message to my
home BBS.  It took 36 hours and 53 min from the time of origination to
arrival!

I sent replies via packet to both John and Bill.  It will be interesting
to see how long they take.

Hi everybody,
I used to do packet with digicom + C-64, but now I've got a clone IBM
and I would like to know more about packet with IBM clones.
I know I could use baycom, but I saw among packet drivers by Clarkson
University a packet driver for the serial port which can emulate
SLIP KISS and AX.25. I read somewhere that ka9q program can be used
with this driver, and I guess I could use an interface between radio
and computer similar to the one I used with digicom (of course with the
right voltages for RS232).
Is anybody else using this program ?
Where can I "FTP" it ?

Thank you very much for your answers !

A couple of things to watch for ..

The Modem MUST have echo turned off BEFORE starting NET or else NET
will interpret all the command echoes as login text and the lot will
eventually crash.

Get rid of the verbose messages so these don't interfere with net either.

The command string 'ate0v0s0=1' works with my modem.

I'd like a table of generator polynomials up to order 10 that can be used

Before I hear loud shouts of "that's illegal"--remember that I'm in Canada,

Well, I got into packet with Baycom/Baymod at $59.95 from Paccomm...It's
really portable (HT, cheap Laptop PC, Baymod modem-in-a-DB9) and works
fine. It does have the limitation of not being upgradable to 9600. If you
get a TNC, you can later install a G3RUH 9600 baud modem inside it..and buy
a new radio, hardware mod it, etc. I'm happy with the cheap solution right
now.

Paul has given a fair snapshot of *current* practice, and a novice
user would be wise to follow this path *today*. But most advanced
packet experimenters recognize it as horribly inefficient, and even
evil, because of the congestion and poor throughput that it fosters.
After the initial thrill of connecting to a BBS or distant user
wears off, comes the cold realization that current packet practice
is worse than 300 baud dial up lines for *communications*.

Nost advanced experimenters recognize that high speed, narrow beamed,
point to point links result in a better network with higher thruput
for all users. New users would do well to review the literature on
these techniques and decide whether they want to become part of the
problem, or part of the solution. Many current users are trapped by
inertia and aren't going to change willingly. The hope of future packet
networks rides on the shoulders of fresh blood entering the ranks
who are willing to lead in a fresh direction.

Packet is a *cooperative* activity. The DXer mentality is the wrong
approach to effective packeting. You should concentrate much less
on your own station and more on the network *system* of stations.
The firmware in current TNCs is horribly at odds with effective
communications *systems*. Real LANs, MANs, and WANs need to be
organized along with effective switching technology to interconnect
them. Along with high speed point to point hardware, and controlled
access moderate speed wide area coverage hardware, this topology
promises *real* communications effectiveness for packet radio.

To: [e-mail]

    There has been a little discussion about commercial TNCs.. I
    began to wonder, if they might be technically compatible with
    those used by hams, when a friend of mine told me that he is
    planning / building a system to transfer data on a commercial
    channel.

    Has anyone tried this?

Interesting.  How come it takes so long?  I haven't been involved
with old-fashioned CW/phone traffic handling for many years, but as
I recall, when things were working right, a coast-to-coast message
took no more than a day.  (Local net - region net - area net takes
one evening.  TCC that night or next day.  Then area net - region net -
local net the next evening).

Of course, it often takes longer, usually due to routing or
delivery problems at the local level.  Is the problem the same with
packet messages?

URGENT!

In Croatia we are using packet-radio network for exchanging
medical and humanitarian data.
As we have also some PSDN connections, we are interesting
to integrate packet-radio and X.25 networks.
Could somebody help us by advising what sofware and hardware
components are required?
We are currently using MicroVax/VMS 5.4 and PC compatibles.
I heard that similar connections already exist and operate
in USA. I must add that I am not an expert in this field,
but all my efforts to find one with such an experience
in Croatia have failed.

Well, it seems to me that a tapped shift register and an exclusive
OR gate is simpler and cheaper. The details necessary to generate
a table for your purposes are available in the ARRL Spread Spectrum
Sourcebook. Basically most PN sequences are variations of a basic
Fibnocci number algorithm. An order 10 PN sequence has 60 unique
maximal length sequences, each 1023 bits long. A linear feedback
shift register with taps at stages 7 and 10 would generate one of
these maximal sequences. If you want to do it in software, it's
easy to code a linear feedback shift register.

That's only easier if you want to use ONE PN sequence in the transmitter.
  If you want to be able to use multiple sequences (as in CDMA), an
  EPROM seems like the easier approach.  Using an EPROM also means that
  you can do experiments to see which sequences work in real-life, and which
  don't, without rewiring your shift-register/XOR gates every time.  I'm
  fundamentally a software dweeb, so my hardware inclinations are towards
  software-driven solutions...

I read the ARRL SS sourcebook treatment of m-sequences (admittedly late
  at night, when my brain was barely functioning), and found it
  heavy-going.  I'll take another slug at it when I'm awake ;-)

no. nntp replaces the combination of compressed batches and uucico.
The main reason I suggested tapping in at the uucico replacement level
is that there has been a large amount work done on full news packages for
many machines.  these packages take care of article expiration,
user interface, collecting and dispersing articles, and all the other
things associated with maintaining a news site.

I've always used straight noise squelch on my 1200 baud packet, and
frankly it seems to work at least as well in practice as anything else.
My observation is that the several radios I've used seem to have
acceptably fast response time (at least we've never had to change timing
parameters because of squelch delay) and the adjustability of the
squelch is a Good Thing -- if you can adjust the squelch so it only
opens on signals strong enough to decode, you can ignore most
interference and the grunge that gets through would likely be strong
enough to interfere with reception, anyway.

The main one is error detection and retransmission on a small chunk
level. Much like Xmodem, packet does CRC data integrity testing and
positive acknowledgements on a packet by packet basis. In addition,
AX25 offers a rudimentary routing function and the amateur TCP/IP
has the full routing functionality. And, unlike most computer communications,
it can be used mobile in motion.

I recently bought a W2A and being too impatient to run around town
searching out components bought an AEA interface cable at the same time
(not recommended: it works fine, but cost $25!).  It uses the same R + C
interface as the older Icom models to a stereo-type phone plug where
the TNC audio input comes from the tip, AFSK/PTT goes to the ring, and
the sleeve is common.  Remember to turn off one receiver or you'll get
audio from them both into the TNC!

Since, as I noted, it's trivial to do a linear feedback shift register
in software, even the most brain dead single chip micro can handle it
in it's spare time, the use of an Eprom lookup is hardware overkill.
Since it's "only software" you can change the taps on the fly. You'll
have a micro in the design anyway to do channel control and protocol
conversion so you might as well get your money's worth out of it.

It isn't as clear as it could be. Simply try coding a hardware emulation
of the example linear feedback shift register in software and you'll see
it's not really complicated.

I am really impressed with the Baycom software.  It is written better than
a lot of the TNC software and is very easily upgradable (I just download
the version 1.5 update via FTP).  A few corrections, however.  The hardware
is made by a lot of companies (my packet modem was made by Tigertronics and
I'm not terribly pleased with their "RS232" interface).  It is small (fits
in a DB25 shell and derives power from the RS-232 port).  However, in
reading the manual for the software, the implication is that it is not
constrained by baud rate at all.  The software can be set to work at any
rate the hardware can handle.  Thus the G3RUH modem, which would have to
added to a TNC to get 9600 baud, could also be made compatible with
Baycom's use of the RS-232 port on the PC and then used with Baycom.

Er, yes on no....   It's supposed to require a license including data
modes, F9 or something for the 'emission type'. Apparently the FCC
isn't too concerned, though. Motorola has been putting up Mobile Data
Terminal systems on various frequencies ignoring the emission and user
restrictions.

Seems like AEA makes a commercial TNC, probably not exactly AX.25. They
probably give you specific info on license requirements.

Last week I had some trouble hooking up a cable between my 411 HT and
the 1270b: I could receive okay, but PTT wasn't working. With some
help from MFJ, I got a cable working to activate PTT (using an
RC circuit on the cable), but now it's putting noise back into
the receive of the radio (about S7), so I can't get anything.
Would anyone know why this would be happening? It's incredibly
frustrating. Thanks in advance for any help...

In a previous article, [e-mail] (Ayman Kayssi) says:

>Are there any advantages to using packet over other means of computer
>communications? Just wondering...

Well, it depends upon what you're trying to accomplish.  The only thing
that I have noticed, is that, relative to landline BBS's, packet is often
PAINFULLY slow.  Part of this is due to the fact that there are many
different stations using the same frequencies.

However, there is all kinds of stuff you can do on packet that you can't do
on landline BBS's.  There really is no such thing as a busy signal on
packet.  And there are plenty of "chat areas" on packet, most of which are
very rarely used.  There are alot more people in packet, I'm sure, than
there are on Internet -- and some of the people on packet are in some
downright exotic locations.

Something that's on packet, but nowhere to be found on landline BBS's is
the National Traffic System.  You can log onto your local packet BBS and
send up to 25 words to anyone in the United States and a handful of foreign
countries.  The message is sent absolutely free and generally gets to it's
destination in a few days to a week.

And, most logically, there is alot more ham related stuff on packet than on
most landline BBS's, and certainly more hams <<Grin>>.

Also, it's pretty difficult to get on a landline BBS from your back yard or
anything ... with a portable computer and an HT, you can work packet from
anywhere there's an ability to get into a packet board.  Oh, also ... there
are packet boards on HF, so it's possible to communicate via computer from
the comfort of your own RV!

Subject: Wanted:  Table of m-sequence polynomials
To: [e-mail]

 M-sequence generating polynomials can be found in several
 publications.  For those not familiar with what this is all
 about, these generating polynomials are used to generate
 pseudorandom sequences for spread spectrum communications
 and for test purposes.  They are also used to make
 "scramblers" to randomize the occurence of bits in some
 modems to aid in synchronization.

 "Digital Communications" by John G. Proakis (McGraw-Hill)
 has a list due to Forney.  It only lists one polynomial for
 each m even though there are often many.

  m   Stages connected to mod-2 adder (OUTPUT IS LOWEST STAGE)
  2   1, 2
  3   1, 3              To construct the generating polynomial
  4   1, 4              instead for say the m=5 one in the list
  5   1, 4              (with connections 1, 4) write 100101
  6   1, 6              where a "1" is in pos. 1 and in pos.4,
  7   1, 7              with another 1 placed in pos. 6
  8   1, 5, 6, 7        (m+1=5+1=6).  This corresponds to
  9   1, 6              the polynomial 1x^5+0x^4+0x^3+1x^2+0x+1
 10   1, 8              or x^5+x^2+1.  This polynomial is also
 11   1, 10             denoted "45" which is obtained by
 12   1, 7, 9, 12       converting binary 100101 to octal.

 Thus the m-sequence generator for the example x^5+x^2+1
 (which has taps at stages 1 and 4) is visualized as:

 out <---------------------------> + --------------
    |                          ^              |
    |                          |              |
       ---      ---      ---      ---      ---    |
      | 1 | -> | 2 | -> | 3 | -> | 4 | -> | 5 | <--
       ---      ---      ---      ---      ---

 where a box with a number indicates a shift register.

 Another source of such generating polynomials is
 "Error Correcting Codes" by W. Wesley Peterson and
 E. J. Weldon, Jr. (MIT Press).  Appendix C lists
 irreducible polynomials (in octal code as described
 above).  Much of this table is due to Marsh (1957).
 The ones that are m-sequence generators are the
 "primitive polynomials".  (Those denoted E, F, G, H
 in the table.)  Some of these are:

   m   Primitive polynomials
   2   7*            Note this is only half of the primitive
   3   13*           polynomials as the reciprocal of a primitive
   4   23*           polynomial is primitive and only 1 of the 2
   5   45* 75 67     is listed.  The reciprocal of 23 or 10011
   6   103* 147 155  is 11001 or 31 (which is in the first list).
   7   211 217 235 367 277 325 203* 313 345
   8   435* 551 747 453 545 543 537 703

 Starting with m=9, there are too many to list here.

 The ones marked with * are the ones which turn
 out to be the polynomial that was in Forney's list.

      In the US, the FCC allows radio amateurs to use
 certain pseudorandom sequences to generate spread spectrum
 signals.  These are the following:

  m   Taps uses in feedback (OUTPUT IS HIGHEST STAGE)
  7   1, 7          (gen. poly. is 203 octal,  010000011 binary,
             or x^7+x+1)
 13   1, 3, 4, 13   (gen. poly. is 20033 octal,
             010000000011011 binary, or x^13+x^4+x^3+x+1)
 19   1, 2, 5, 19   (gen. poly. is 2000047 octal,
            10000000000000100111 binary, or
            x^19+x^5+x^2+x+1)

 These correspond to the corresponding ones in the Forney list
 once the stages are re-numbered to accound for the difference
 in numbering the stages.  (Subtract from m+1 to do this.)

 I have seen pseudorandom maximal length sequences transmitted
 on HF by various US State Department stations.  These used the
 polynomial x^9+x^5+1 (which is 1000100001 binary or 1041 octal
 --which is the reciprocal of the polynomial 1021 octal
 in the Marsh list).  This will give a pseudorandom sequence
 of length 2^9-1=511 once seeded with any not all zero 9 bits.

Well, it depends on the specific CDMA scheme. You can use the same PN
sequence at each transmitter if you have some way to assure that each
transmitter will use a different part of the sequence so they won't
coincide at the receiver. Qualcomm's CDMA system works this way --
everybody uses the same "short" and "long" PN codes. Collisions
between the short codes on the forward links are avoided with
allocated timing offsets controlled by global synchronization to GPS.
Collisions in the long code on the reverse links are avoided by using
offsets that depend on the unit's address.  The latter technique is
probably applicable to what you want to do as long as the receiver has
some idea of where in the long sequence it should search for
acquisition.

Another alternative is to use a family of Gold codes. These can be
generated with a pair of PN generators (using different polynomials)
whose outputs are XORed. You generate different sequences by setting
different initial starting states in the two PN generators.
(Equivalently, you can start all of the generators at the same state
and take different taps off them for combining.)

GPS works this way -- each satellite has a unique Gold code generated
from a standard pair of PN generators. The polynomials used in the
latter are the same for all satellites: 1 + X^3 + X^10 and 1 + X^2 +
X^3 + X^6 + X^8 + X^9 + X^10. Only the starting states for the two
generators differ for each satellite.

This second approach is useful when you have to use a short sequence
to make brute-force acquisition feasible (i.e., searching the entire
sequence space at the receiver) and you cannot guarantee that multiple
transmitters sharing the same PN sequence wouldn't "collide" at the
receiver.

BTW, an excellent overview of GPS's use of spread spectrum is in the
book "Radionavigation Systems" by Boerje Forssell, published by Prentice
Hall in 1991. ISBN 0-13-751058-6. I found it on my last trip to Computer
Literacy. I highly recommend it as a very readable reference. In addition
to basic principles, it describes the specifics of Omega, DECCA, LORAN-C,
DF, VOR, DME, ILS, MLS, Transit, GPS, GLONASS, TSIKADA, Starfix, Geostar
(now defunct), and Navsat (proposed). About the only one missing is
Qualcomm's QASPR system in Omnitracs.

  Have you been trying to find the perfect packet radio communications program
for your Macintosh computer?  Well, you may have just found it.  Virtuoso is a
communications program written specifically for packet radio.  This means that
it has features that you as a packet radio operator need and also packs a lot
of bells and whistles to keep your packet radio communications smooth and
effortless.  The current version is 1.3.

  Virtuoso is a shareware program with a price tag of only $20.  It is
available on America Online, GEnie, CompuServe, and various ftp sites.

The following is a list of some ftp sites where you can find Virtuoso:

ucsd.edu:
    /hamradio/packet/misc

hpcsos.col.hp.com:
    /packet/ke0ph

pacific.mps.ohio-state.edu:
    /public

sics.se:
    /pub


Some features implemented in Virtuoso v1.3 include:

  -Word Mode - Useful for RTTY and AMTOR.
  -A powerful scripting language to automate routine tasks.
  -Automatic execution of a script when starting and quitting.
  -Save incoming text to a disk file.
  -Send a text file from a disk.
  -Append a selection of text to the end of an existing file.
  -Print a selection of text.
  -Column counter display
  -Word find - useful for finding the last time you heard someone.
  -Spelling checker(Dictionaries Necessary). Checks the words as you type them.
  -Split screen (rx and tx) which can be adjusted easily.
  -Windows can be scrolled up to see previous text (Up to 32000 characters).
  -Full font, size, style, and justification support.
  -Supports 300 - 19200 baud.
  -Keyboard buffer window so you can type in long messages of text
     before they are sent over the air.  This window supports full
     cut, copy, paste, clear, and undo like any good text editor
     does.  To send the message, just hit Command-Return.
  -Use the control key (or the command key if you don't have a
     control key) to send control characters to the TNC.
  -Option to strip off line-feeds, or all control characters on
     the input before it's displayed on the screen and saved to
     disk.  Control-G's can be passed through to beep your computer
     if you want.
  -Virtuoso can automatically put your TNC in KISS mode upon
     shutdown, and take it back out at startup.  This is useful for
     TCP/IP'ers.

  This file has been checked for viruses with Disinfectant 2.5.1
before uploading.

  If you cannot find Virtuoso anywhere, send me some e-mail and I'll get
you a copy.  I also appreciate any and all comments, suggestions, and
criticism.  That's the only way I'm going to know what to fix and improve
for the next versions.

  The PK-90 manual I've looked at indicates the PK-90 is essentially
the same design as the PK-88. The differences are quite minor; in fact,
the PK-90 could be *upgraded* to PK-88 level quiet easily. While I
haven't tried it yet, the manual indicates that interoperation with
regular AX.25 nodes should be a snap.

To: [e-mail]

Greetings, apologies in advance if this is a FAQ.  Please feel free to refer
me to an FTP site -- i have looked for but not found the data i'm looking for.
I have no experience at all in radio.  Next year I will be attending college
in annapolis maryland, across the street from a naval academy, which has what
was described to me as a "digipeater".  Since i wish to stay on the net at
school i have begun investigating packet radio as a means to internet access.
Unfortunately, the documents I have found which deal with this topic are of a
highly technical nature, only comprehensible by those with radio experience.
Is there an introduction to this topic intended for people with internet
experience but no knowledge of radio?  If not, could some kind soul furnish me
with said introduction?  My objective is simply to get on the net via radio,
although I've heard tell of many other wondrous things that can be done with
packet.  I am particularly interested in knowing what kind of money is needed
to get xfer speeds of 9600 baud or above, how the routing works (i assume i
would have my own IP address?), and whether the speeds achieved by radio are
quick enough to allow for practical remote login.
Thanks in advance for your tolerance of a radio neophyte.

They're not TNC-2 clones in that you can't plug in H/W such as 9600
baud modems and the like into them.


They are, however, a cheap way into packet.  Reliable.

The document entitled "Beginner's Guide to TCP/IP on the Amateur Packet
Radio Network Using the KA9Q Internet Software" is again available by
anonymous ftp.  The new location is ftp.eecs.ucdavis.edu.

Version 2.0 of the guide documents the use of NOS 911229 (PA0GRI v2.0h)
and BM v3.3.2.  The document is available in three forms in the
directory pub/ka9q.

"nosbgnlp.zip" unzips to a 66 page ascii "line printer" document,
which can be printed with the UNIX lpr command.

"nosbgnps.zip" unzips to a 54 page PostScript document, which can
be printed on a PostScript printer.

"nosbgnpr.zip" unzips to a 66 page ascii "print" document, which
can be printed using the DOS print command.  You will need to send
control codes to your printer to control the page offset and you
should turn perforation skip off.

I am unable to provide access to this document in any way other
than anonymous ftp.  Those of you who do make it available in
other ways (on a BBS for example), please let me know and I can
pass this information on to those who inquire.

Comments and suggestions for change to the document are welcome.

Subject: WHY HASN'T SOMEONE DONE THIS!?
To: [e-mail]

Like many hams, I enjoy scanning/monitoring as well.  More and more, I
keep encountering non-amateur packet protocols being used for business
or other services.  Most of the tones seem to be the same as amateur packet,
but just using a different packet format.  Which brings up my question:

Why hasn't someone marketed a modem that demodulates the tone pairs,
then hands the demodulated binary off to software that breaks down
the packets.  Such a company could then sell a single software package
that could interpret multiple protocols or different modules for
different protocols.  The PMP modem everyone built (including myself)
does this, but I don't have the knowledge necessary to
to modify the software for other protocols.

Anyone have any constructive thoughts or suggestions on this?

Yeah, this newsgroup is for discussing how to can tomatoes.

No seriously, this newsgroup is also aliased to misc.misc.me.too, which
is a central depository for "me-too" postings.  Paid Usenet employees
read this newsgroup and are required by net-regulation to research all
me-too questions and mail them to the original posters.

Lest someone accuse me of being TOO facetious (who, me?), I'll point out
that the FAQ is cross-posted to this newsgroup and news.answers (where
it still might be on your news sppol) and is archived at
ftp.cs.buffalo.edu under pub/ham-radio/faq_packet or at
pit-manager.mit.edu under pub/usenet/rec.radio.amateur.packet/(some
long name).  Other documents of interest might include the general
amateur radio FAQ and the Elmers list.

Good luck.  If you visit the pit-manager archives, check out
pub/news.announce.newusers.  Feel free to E-mail me if you have any more
questions about amateur radio or the net in general.

I can't pass this one up... I've been using Macintoshes next to, and
with, my ham station for over eight years. Macintoshes are very well
shielded, especially the compact Mac models. I have demonstrated the
Mac running MacPacket(tm), with TNC-2s and other TNCs with a handheld
2 meter rig more times than I can count. The only problems I have
run into is that the TNC puts out lots of emi that bothers the radio
receiver. Turn off the TNC, and things are quiet. The answer, of course,
was to move the antenna away from the TNC... It is an interesting
experiment to move an HT around the computer in close proximity. You
will see some noise, but probably not too much.

I have noticed some problems with HF operation, but then I was using
a short piece of wire for an antenna. When the station is connected
to a decent external antenna, things are great.

The big reason for things being quiet is obvious once you open up
the Mac. They have shielding and emi coating everywhere. If everyone
did as good a job with shielding, there would be few EMI problems...

The modular Macs (Mac II family and LCs) aren't quite as quiet as the
compact Macs, due to having more openings in their chassis. Still, there
is plenty of shielding, and things are far quieter than most other
systems. The biggest cause of problems seems to be the CRT. Of course,
this is probably the case with most systems. It just helps to have it
inside the shielded cabinet ;-).

>Any favourite station computers that do not use 80..*[68] cpu's?

Well, my first packet station was built around a 6502. In fact,
it was probably the first dedicated packet repeater, way back in
1981. Still works, too!

I second what Jack said--they're pretty quiet. I just scanned the entire
2m band, and the TNC was the source of all the noticeable hash. It's been
a while since I've had an HF rig set up, but I think it was fine, too.
(Please note, of course, that my comments do not represent a guarantee from
Apple that your experience will be the same.)

(FYI, at the moment I'm running my packet station from a Mac Plus; the
2m antenna is acutally draped partly across the computer! And the Mac II
I'm writing this on is about three feet away from the antenna.)


>       Are there C compilers and assemblers for the Mac?

Of course! I know there are at least some from Apple (the MPW series)
and Symantec (THINK); there may be others. There are also some C++ compilers.

    Not exactly IC-W2A to PK-232, but I use my W2E together with a
    PK-88. I don't think they differ too much..

    You need four wires from the TNC: ground, mic, speaker and PTT.
    I cannot tell for sure, which wire is of which color, as the
    wire I had, is not necessarily the original. Anyway, you need
    to connect the speaker wire to the tip of the W2 plug, mic wire
    to the center ring, and ground to the base ring. Last, connect
    PTT wire to mic via a 10 kilo-ohm resistor.

    After that, just power up, check for smoke and on the air..

    It might be a good idea to turn off the battery saver on your
    W2. It still works with 1:4, but it works better when Off.
    Setting it to 1:16 is a bad idea, especially if the channel is
    not continuously crowded..

    I wonder, if this would be available somewhere via a mail ftp
    server or something for those of us that do not have ftp, but
    mail only access. (Yes, there are still lots of locations, that

I do not believe this is correct.  I believe the PK-88 has a standard
modem disconnect.  The PK-232 on the other hand does need a special disconnect
header that is provided by TAPR in Tuscon, Az. for a small fee.

If it's of any interest, the Kantronics "RF Packet Modem" appears to be
just a KPC-2400 with a different EPROM (and manual, and labels).  Get
the EPROM upgrade, and you're in business!  I don't know what the "RFPM"
runs, but AX.25 it ain't.

Someone here in Australia was selling them real cheap, because they didn't
work with the local BBS's.  Silly boy :-)

Extremely easy. Macintosh computers are extremely well-sheilded. They pass
FCC standards for Class B (home-use) computing devices. Each pin on the
back of a Macintosh Classic is filtered against RFI. The inside of the case
is coated with RFI-proofing conductive coating. All cables are
shielded.

THINK C is probably the most popular development environment for "hobbyist"
programming on the Mac. It includes an inline assembler that most find
sufficient for development.

I happen to prefer THINK Pascal, but then, that's just me.

I have a Mac SE (not unlike the Classic) in my shack and wouldn't trade
it for any DOS computer.

I forgot to comment on this one. MacPacket(tm) (note: stupid lawyers...)
was written in Aztec C several years ago. Aztec still ships a very nice
C development system for the Mac. Price is around $100.  I now do all
of my development using Apple's MPW development system using either C,
C++ or assembler. The environment is very much like the Unix development
environment, only I like it better. Depending on what features you want,
MPW can be pricey. The whole package is best bought as an ETO subscription
for about $1K, although if you just want C, it should be much less.
Lots of folks develop excellent programs using Think C, which costs in the
$200 range mail order. It has a Mac application front-end (i.e. not
command line), is relatively easy to use, and has some C++ like features.
All three packages I mentioned have source level debugging, although you
pay extra for MPW's SADE debugger.

Essentially, if you want to hack and have a good time, look at Think or
Aztec. If you are going to do professional development go with MPW or
Think. If it will be a large development team, MPW has features (like
Projector, the project management system) that greatly ease the effort.

I hope I didn't give more info than was wanted. Essentially the answer
to the question is that you can do anything with the Mac you want.
Have a great time doing it!

> Any favourite station computers that do not use 80..*[68] cpu's?

The Amiga is a great computer because the operating system is true
multi-tasking.  You can use any of the many available terminal emulator
programs to talk to the TNC and/or send and receive files.  Meanwhile,
you can have a separate window running any Amiga word processor to read
files that have been received, and prepare files to send.  While all
this is going on, a third window can send a file to the printer.  And
another window can be used to run a log book program, and ...

For example, connect to a BBS, request a listing of postings, and send
that to a file.  Bring up the file in the editor, and look for postings
of interest.  Use the terminal window to tell the BBS what file you want
to read.  Meanwhile, the contents of the listing file don't scroll off
the screen!

In the 80..*[68] world, you have to buy a special program to attempt to
do all this, and you are forced to use whatever editor, etc someone else
chose.

I have been told by a manufacturer of plug-in 9600 baud modems for
"TNC-2 clones", that the PK-88 is not a TNC-2 clone and will not work
with their board.

DOES ANYONE KNOW OF A SOURCE FOR A SPECTRA STYLE CONNECTOR? IT IS AN

I suspect it's one of those special ribbon cables with exposed flat conductors
at the end.  According to Tandy, this port presents/accepts TTL-level RS-232
signals.  Kevin's goal is to use the port for a second TNC (he already has
one TNC on the first serial port).

I downloaded baycom20.zip and tcm3105.zip from wsmr-simtel20.army.mil(?).
the tcm3105.zip contains a postscript file of a circuit diagram.  The
questions I have are:

    1.  Has anyone built the circuit in this diagram and do you have
    any advice on building it?

    2.  At the bottom of the diagram it says "sheet 1 of 2".  Is there
    another page to this diagram that I'm missing? And, can you send
    me a copy of it if there is?

    3.  I'm not real familiar with integrated circuits, is the TCM3105
    a common device that I can pick up at Fry's Electronics?

In the zip file I did not find any directions on building the circuit so
any comments, suggestions, advice will be welcomed and appreciated.

One of the strongest reason to use THINK C 5.0 is that it has
a *very* good GUI-based source-level debugger.

From: [e-mail]
Subject: Connecting and Grounding the PK-232 to the TS450S/690S ( LONG)
To: [e-mail]

Sub: Hooking the PK-232 MBX to the TS690S or the TS450S
     and grounding the PK-232 to reduce distortion on SSB
     transmissions.

I would like to take this opportunity to thank everyone who replied to
my question about connecting the PK-232 to the TS690S. I eventually
had to replace Q5 and the PK-232 now keys the 690S. In particular, I
would like to thank Dick (KD5VU) and Erich (KA6AMD) for their input
on how to connect the PK-232 to the 690S and the 450S. The following
information has been edited from that which they had sent me earlier.


1.      HOOKUP AND PIN ASSIGNMENTS


Dick uses the ACCY2 port of the 450S to hook up his PK-232 for AFSK
operation. The following list details the Pin Assignments which Dick
uses for AFSK Operation:


PK-232  J4                      TS-450S (ACCY2 PORT)


Pin 5 RED     PTT               Pin 9  PTT
Pin 4 BROWN   GND               Pin 8  GND (Do not use Pins 4 or 12)
Pin 3 BLACK   -                 -      Not Used
Pin 2 WHITE   AFSK-OUT          Pin 11 AFSK-IN
Pin 1 GREEN   AFSK-IN           Pin 3  AFSK-OUT


As Dick indicated to me, it is important to ensure that you do not
overdrive the rig. Since neither the 690S or the 450S has a Tx monitor
you will need to watch the ALC setting after setting the desired power
level and AFSK audio output from the PK-232. Please note that it takes
very little Mic Gain to overdrive the ALC. Also - the 450S and the 690S
are rated as 100% duty cycle units. I personally felt more comfortable
setting the power level to 50 - 75 watts although the 690S manual
suggests setting the power level to 100 watts.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Erich (KA6AMD) hooked up his 690S to the PK-232 in order to use
FSK for digital communications. The hookup he uses works well for
him on all the digital modes and is listed below:


PK-232                          TS690S (ACCY2)

J7-4    FSK KEYING              2
J4-1    Rx  AUDIO               3
J4-4    AUDIO GROUND            4
J7-2    FSK AUDIO               8
J4-5    PTT                     9
J4-2    Tx AUDIO                11


On the PK-232 J4 is Radio Port 1. J6 is Radio Port 2. Either port may
be used.


2.      GROUNDING PROBLEMS

Both Erich and Dick indicated that they had distortion when
transmitting on SSB when the PK-232 was hooked to their rigs.
The Kenwood reps were not able to help them with regards to
the problem. Erich suggested that I Disconnect the PK-232 when
using SSB. Dick also had little luck with the reps, but he was
able to determine that there are floating grounds in the ACCY2
port of the 450S and 690S.

Dick appears to have corrected this problem by grounding the
PK-232 to the 450S. As Dick noted (edited :-))(please note that Dick
is using AFSK):

    I have set my rig up for AFSK operation and I have grounded my
TS690S as Dick has suggested. I have not yet had problems with
my audio when transmitting on SSB.

Once again - Thanks to all who replied. And as Erich noted earlier:

ANYTHING YOU TRY WITH YOUR TNC (PK-232) AND YOUR RADIOS IS YOUR
RESPONSIBILITY.

...or get an operating system that does DOS better than DOS...If you have a
386SX or better, and can get RAM above 4 MB, take a good, long look at OS/2
2.0. You'll be impressed, even if you just want to multitask DOS and Windows
programs (a job that it beats Windows at, hands down).

I do this on my Mac SE. Can't everyone?

To: [e-mail]

A friend just loaned me a Heathkit TNC HD-4040 with no cables and no
manual.  It has KISS proms in it and I have the latest NOS I could find.
Now I just need to make a cable from the DB-9 on the TNC to the radio.

I am just getting started in packet.  And I'm on vacation for a week.
(But, I will be checking my e-mail regularly and newsgroups when I can.)

Thanks.

North West Packet User Group, (NWPUG) sell a set of Node/BBS maps that
cover the UK.  The UK is split into two A3 sheets, and the set costs
1 pound.  We (NWPUG) attend most of the rallies in the North West.

If you cannot attend the rallies in our area, then you could order
them through me.

Subject: Packet Networks
To: [e-mail]

I have some questions about packet networks. I am really new to this subject,
but I am very interested in it.

1- Is it possible to use HF for packet communications? And what is the
   current used frequency band? (VHF? Microwave?)

2- What is the current limit on the baud rate that is possible? 9600?

3- Is TCP/IP the best protocol for a radio packet-based network?

4- How efficient is it to have several transmitters transmitting at the same
   time and causing all sorts of collisions?

5- What is a good reference on all of this? Does the ARRL publish any books
   on this topic?

Thank you very much for your help. I'm looking forward to learning more about
packet radio and using it soon.

 They're also not TNC2 clones in that the EPROMS aren't compatible,
the command set differs, and I wouldn't be at all surprised if the
hardware is considerably different.  They don't use the 2206/2211
chipset, and cannot be run open-squelch (very important if you want
better than mediocre performance) without adding a DCD state
machine like true TNC2 clones can.

 To stop a rumour in the making, yes you _can_ use 9600 baud modems
with them, but as you (correctly) point out, you "can't plug ... 9600
baud modems ... into them", i.e. inside.  (Even if they had an
internal header, there's physically no room).  They have to be
externally mounted, and the PK88 must be slightly modified (cut a
trace and tack a wire) to bring out a x16 clock.  AEA, in their
infinite wisdom, brought out a 9600 Hz (x1) clock.  All other
necessary modem connections are brought out through the DB25.

> They are, however, a cheap way into packet.  Reliable.

 Yes - and so are the true TNC2 clones.

I know almost nothing about radio, packet or otherwise.
At Apple, we have a service that gives us stock quotes,
which we receive over a radio.
What kind of service is this ? Does it cost money?
I have seen things like silent radio at the post office,
Are there other services like this?
How can I buy that service?
maybe news feeds, weather feeds, anything?
I would like to hook it up to a mac.
What kind of hardware do I have to buy to receive this?
where do I go to buy It?

Yes, *possible*, but not pleasant, due to the fact that the mac is
a machine with cooperative multitasking and except on the most expensive
models, the CPU is involved in every byte of every disk transfer.

Albert Einstein, when asked to describe radio, replied: "You see, wire
telegraph is a kind of a very, very long cat.  You pull his tail in New
York and his head is meowing in Los Angeles.  Do you understand this?
And radio operates exactly the same way: you send signals here, they
receive them there.  The only difference is that there is no cat."

Here we go again... Try 2. An attempt was made to get this exact same
argument started over on the tcp-group. Sorry, but it won't wash here
either. First, we have far too many better things to do with our time.
Second, both forms of multitasking have their place. I will still
maintain that for data comm systems, or for that matter just about any
real time system, I would much rather have a non-preemptive system. When
you begin to realize that state machine programming solves many real-time
problems extremely well, you might begin to understand why it's better
not to have what you are doing interrupted by an OS doesn't know any
better.

Now we all know that each computer has a specific task that it solves
quite nicely for its user. Obviously you like the Amiga an awful lot.
That's fine. Others happen to like Macs, and still others DOS based
PCs. There are probably even a few CP/M users around. This group is
meant for discussing ham packet radio topics. Shall we keep it that
way?

Or do you really want me to point out that my Mac was the first computer
to drive the 56K packet modem at true 56K???

Alinco mods to use mic connector for 9600 baud data

TRANSMITTER

Remove R31
Remove C40 and replace with one end free and other end
reconnected to pin 7 of the VCO board. Connect a jumper between
the now free end of C40 and the hot end of C35. The Mic input is
now connected directly to the VCO.

RECEIVER

Disconnect the pink wire that goes to data output on the
mic connector from the PCB and reconnect it to pin 2 of the IF
board connector. This eliminates the low pass filtering on the
discriminator.

Softkiss version 1.1.t connects a modem directly to a macintosh.  This saves
having a TNC.  Softkiss will work with 300 baud HF, 1200 baud VHF and
higher baudrates.  The software is functional at this time but the user
interface
is not pleasent yet.

Softkiss is available akutaktak.andrew.cmu.edu [128.2.35.1] in
/aw0g/softkiss.1.1t.sit.hqx.  You also need Phil Karn's Net/Mac program
if you don't have it, it is available as /aw0g/netmac22.sit.hqx

Changes since the last release:  Well it acutally works.  I connected
to my local packet bbs for a couple of hours last night.  There is
more of a manual on how to hook it up.

BALONEY!

While I'm reading your message, I've also got three other applications
running: downloading from CIS, running MPW and editing a list of files,
and of course I have the Finder. There's nothing unpleasant about it.

So? That has nothing to do with multitasking.

> [DMA?  What's that?]

Direct memory access. It permits the CPU of a machine to perform other tasks
while transferring data into or out of main memory.

(Note that all 386 and 386sx machines have DMA. Note that none of them use it
for hard disk i/o because it is too slow)

--

Andrew, you clearly have not used a Macintosh for multitasking and shouldn't
be posting such untruths to the net. Cooperative or not, it is still
multitasking.

  Both the TNC-2 and the PK-88 use a Z-80 processor. The TNC-2 uses a
Z-80 SIO chip, and the PK-88 uses a Z-80 SCC chip. The TNC-2 uses a
state machine ROM for recovery of clock in the incoming data; the PK-88
uses the digital PLL internal to the Z-80 SCC. Digitally, they're quite
similar but not the same.

  As for the modem, the TNC-2 uses the Exar analog 2206/2211 chips while
the PK-88 uses the Am7910 "World Chip". The 2206/2211 modem is tuned by
a combination of resistors and capacitors; it may require re-alignment
from time to time. As Mike points out, the 2211 demodulator does indeed
provide a "Lock Detect" signal which can be used a DCD indication. Since
the modem is tuned by resistors, it is not easy to change the tones in
use, for example, when switching from 1200 baud to 300 baud. I recall the
TNC-2 provides a method to make this a little easier by mounting the
tuning resistors on a DIP header.

  The Am7910 in the PK-88 is a DSP telephone modem; the Carrier Detect
output simply indicates the presence of any noise on the channel over
a preset level. It cannot be used as a DCD indication. The Am7910 is tuned
by a crystal fixed at 2.4576Mhz (in the PK-88, this clock is derived from
the 4.9152 Mhz Z-80 clock). The PK-88 allows the switching of modem tones
from the TNC command line. Adding a TAPR DCD State Machine to the PK-88
is quite easy; it took less than an hour to build and install the kit
in my PK-88.

  Research indicates the Am7910 is superior to the XR2211 demodulator with
respect to the Signal-Noise ratio. A paper published in the Sixth(?) ARRL
CNC suggests a 12dB difference in required SNR between the two chips, but
I recall the XR2211 implementation used in that research was flawed; my guess
is the XR2211 implementation in the TNC-2 is probably requires 2-3 dB better
SNR for the same error rate as the Am7910 (if someone has a copy of the
K9NG article on the TNC-2 modem error rate, I'd like a copy)

  Given the superior performance of the Am7910, ease of control, and
precise frequency control, I'd select the PK-88 with the TAPR DCD State
Machine any day over the TNC-2 for 300 or 1200 baud operation. If you
are going to use an external modem, the two are essentially equal.

P.S. I recently purchased a few of the SSI 73K302L modems; these are low
power, single +5V supply Bell 212A/103/202 modems. They require 35mW @ 5V
and are specified at rather impressive SNR performance; once I get one
working, I'll report the results.

One gotcha, at least with my PK-88 (close to two years old, now): In KISS mode,
it does not accept a packet longer than 1K. I don't know if AEA has fixed this
one in later releases. On my local network, where 4-5K packets aren't uncommon,
this got in the way a bit... It doesn't blow up or anything; it simply drops
the packet on the floor.

True, the Macintosh does use cooperative multitasking.  But you see, with
well written applications, the user never feels the difference.  In fact
the application can use cooperative multitasking to its advantage in that
it knows EXACTLY when it's being swapped out.

For what do I deserve such a flame?   I was simply stating a fact.  All
of your examples were and are possible on the Mac.  I never said that it
used pre-emptive multitasking.  Don't you have anything better to do with
your time than to flame people?  Get a clue.

Hi all -

I'm playing around with a Baycom modem & the 1.4e Software - I'd like
to find out a few things which did not get explained in the manual.

    * Monitor Display - What are all the codes displayed.
      Most of them correspond directly to the AX.25 spec, but
      some of them are unknown to me.  Does anybody have a
      summary of these codes and what they represent?

    * How does one support a YAPP transfer under the using
      the Baycom setup?  If not, then are the srcs available for
      modification as long as it is feed back to the authors?
      If not, I suppose one could use the PMP software with the
      Baycom modem (same basic hw theory).

    * Are there alternative Software solutions to using the
      Baycom SW directly?

    * Is there a Mailbox mode available?

Thanks,

Terry Domae

Those last two lines should be

It was a typo when composing the article.  I got it right when I was configuring

Subject: configuring PK232MBX for KISS
To: [e-mail]

I just got a PK-232MBX TNC the other day.  So far I've just been tinkering
around with some local BBS's, but what I'd really like to do it get into
TCP/IP.  For now, the only thing I can run NOS on is my HP95LX palmtop
computer.  I've obtained the version of NOS compiled for this computer,
as well as the reference guide and the Beginner's Guide to TCP/IP.

I used the latter document to setup an autoexec.net file (at least a first
cut at it), but I'm stuck when it comes to getting my TNC into KISS mode.
There are specific instructions in the Beginner's Guide for setting
up the PK-232, but I'm having trouble with them.  The Guide lists the
following sequence of commands:

START 0
STOP 0
XON -
XOFF -
XFLOW OFF
CONMODE TRANS
HPOLL OFF
KISS ON
RAWHDLC ON
PPERSIST ON
HOST ON

The trouble is, after entering the KISS ON command, my TNC will refuse
to accept any more commands until I break out by hitting control-C three
times.  At that point the value of KISS is $00 (i.e. off).  My first thought
was to move that command to the end of the list, but the HOST ON command does
the same thing.  There doesn't appear to be any way to get all of the
commands in.

Just for fun, I tried running NOS without entering the last 3 commands,
just leaving the TNC where it was after I typed KISS ON.  I could ping,
telnet, ftp etc. to *myself* but trying any other address caused NOS
to hang (or just keep trying indefinitely).  When I was in my terminal program,
keystrokes caused the STA light to flicker, but there was no flickering
when I tried to connect from within NOS.  Typing "tip ax0" in NOS and
then typing on the keyboard *did* cause the light to flicker.

I'm pretty sure my TNC isn't set up correctly for NOS, and because of that
I don't know whether NOS is set up correctly.  Can anyone help?  Also,
is anyone familiar with the TCP/IP activity in the Seattle, WA area,
especially with respect to what frequencies are used for TCP/IP traffic?


Thanks in advance,

Subject: Header spec
To: [e-mail]

In regards publish more BBS specs, here is what I believe is the
current header spec.

Header spec -- Originally from NK6K

Required items
  1) Receive time
  2) BBS call
  3) Message number

Receive time
  1) Must start in first position.
  2) Time zone optional at end (1 character)
  3) Format: R:yymmdd/hhmmz

BBS call and message number
  1) Two formats permitted (the W0RLI standard and the WA7MBL standard)
    "nnnnn@bbbbbbb" and "@:bbbbb #:nnnn"
  2) The callsign was later extended to include the hierarchical address.
  3) Everything after the bbs callsign to the next field start is
     ignored.

Optional items
   1) General format of "f:dddddd" where f=field identifier and
      dddddd is the data.
   2) Field identifiers in general use:
      $: for bid
      O: for originating station.  Was needed way back when some
         old BBS code dropped this data
      Z: for zip code.  Zip codes preceded hierarchical addressing.
         There was some effort to standardize on routing using these
         but along came hierarchical and the effort died.

I have an Azden PCS-2000 2 meter FM rig that I would like to use for
packet radio.  The microphone connector is a 12 pin type that is
unavailable from either Radio Shack or the local electronics supply
house.  The 12 pins in the connector are arranged in three rows of four
each.  I called the Azden dealer in Georgia, but they no longer have any
connectors or microphone cables with connectors in stock.  The
operator's manual is very little help.  It lists p/n EC-80 which is the
cable with connector, but no part number or manufacturer for the
connector.  Amateur Wholesale Electronics was the only source of parts
listed in manual I have.  Does anyone on the net know where I could
obtain the female mic connector, cable with connector or even the whole
microphone for this rig?

Actually, the latter aspect (of crashing the system when an application
crashes) has NOTHING to do with cooperative vs preemptive multitasking.
It has more to do with memory protection and proper system resource
management. Either can exist in a cooperative or preemptive multitasking
system.

For the record, Apple's System 7 is much better about keeping the
system alive when an application crashes. System errors will terminate
that application, leaving the others running. Of course, if certain
system resources are corrupted in the process, the entire system can
lock up, but that just doesn't happen very often.

This is in reply to Bob's ([e-mail]) question: "[How do] I
... do packet at 9600 baud."

First:  whoever told you that you need a modem to do packet radio is not
completely correct.  You need a modem capable of sending at 9600 baud if your
TNC is incapable.  From reading your post, you already have a TNC.  Is it
capable of sending at 9600 baud.  Because of bandwidth limitations, you are
only going to be able to send reliable packets at 300 baud on HF, and 1200
baud at VHF.  If you are going to choose another medium such as telephone or
microwave or via satalite, where you have greater bandwidth, then you will
have no problem with 9600 or greater baud rates.

The speed at which your computer will talk to your TNC or modem, is dependent
upon the CPU speed of the computer.  If you are using an older 8088 IBM
clone, don't expect to use anything greater than 2400 baud.  If you are using
a 286 class machine, depending on the speed of the CPU, you can go as high as
9600, and with most 386 (and higher) machines, you should have no problems at
9600 baud or possibly a little higher.

I use packet to link up to the Franklin Radio Club's DX cluster.  This is
good for dx spotting, and helps you to locate the countries that you need.
This won't help you work the station, but it takes the pain of locating the
rare one out of the task.

Tower has tilt over base mount and requires a 2 by 2 by 4 foot concrete base.  The tower is 12 inches on aside, and would require bracketing to a house or guying to insure stability ( like any typical tower ).  It is similar in dimension to a RHON 20 or 25 model.

The tower is in great shape and requires no clean-up.  Don't miss this bargin!!

    Why on earth would anyone put 30 MB of operating system on a computer to
    use amateur radio.  We have been a beta site for 2.0 for quite some time

I use OS/2 on my computer to do many things... like programming... running
DOS applications, etc.... I also happen to be a ham radio operator... and would
like to know if anybody else is using OS/2 with ham radio.

I strongly disagree.  OS/2 would make a fine operating system for
amateur radio applications.  True multitasking should prove extremely
valuable to amateur radio operators.

The entire extent of my knowledge with respect to amateur radio
applications is that KA9Q/NOS is available in an OS/2 version (with
partial PM support).  It presently operates only with SLIP, but that's
fine for amateur radio.  It looks like an interesting package.  You
can obtain it via anonymous ftp from ftp-os2.nmsu.edu, directory
pub/downloads/tcpip (though that is subject to change).

I have built the BAYCOM modem using a TCM3105 .
I put it inside a D25-D25 adaptor connector without using a board.
The most important modifications is to add a back to back pair of 1N4148
(or similar) in parell with the R9. So it protects the TCM3105 from strong
audio signals from the speaker that may distroy the chip.
Also there is an error in the schimatic.
There is also an typo error . Between D2 and IC2C the resistor is R3 (not R2).
It is 2.2 Kom.
The most importand : it works great !
Both software and hardware are great.
Also exept BAYCOM exist TFPCX & SP 6 ( a baycom & pmp driver for super packet)
and ax25drv a FTP driver for tcpip.

Subject: TCP/IP and packet radio
To: [e-mail]

Hello:

I am new to the list as well as new to packet radio. I would like your
help on the following:

I have connected a PK88 to my PC and am running PACKRATT II software.
So far I have had pretty good success at making connections. Now I
would like to attempt implementing TCP/IP.

I understand that one can run TCP/IP. I would like to know exactly what
is required to do this (if in fact it is possible on a PK88)...

for instance:

    1. Does the PK88 support TCP/IP usage?
    2. Where do you get TCP/IP?
        - Does it include FTP, TELNET, TN3270?
    3. What configuration is required on the PK88 and the PC?
    4. What else is required (ex: min dos version...)?
    5. What is KISS mode?
    6. I have heard that you must be in "KISS MODE" to run
       TCP/IP, is this correct?
    7. Also, *am* I currently able to connect to net/rom nodes and then
       from there connect via TCP/IP to other locations?
        - If so what net nodes offer this capability?
    8. Are there gateways to the internet?
        - If so what are they?


            I appreciate any help I can get.

Easy! I don't just want to run amateur radio! I want to use it for other

I'm running the WG7J variant of the KA9Q NOS tcpip program for amateur

of a TNC) to drive a 56Kbps radio channel.  For more info on OS/2 2.0

This isn't true.  It has been shown that a 9600 baud packet signal
generated by a K9NG/G3RUH modem fits within the legal bandwidth
requirements on 2M.  At 220 and 440 MHz, speeds up to 56KB are legal and
possible.

Most TNCs can hack 9600 baud packet, though some may have trouble unless
you increase the clock speed (often a matter of moving a jumper, and
maybe putting in a couple of faster chips).  The 9600 baud modem can
sometimes be mounted internally, or if space doesn't allow can be
external to the modem.  But in any event, you will not be able to use
the TNC's internal modem.

I have seen an XT machine running at 56KB, but admittedly that was with
a special plug-in card that took the place of a TNC.  But an XT <can> run
at 9600 baud on the serial line with most terminal programs that do
interrupt-driven instead of polled asynchronous communication.  And, by
using a $15 replacement chip on the serial card (a 16550AFN), an XT can
run easily at 19.2KB on the serial port.

I run a 286 with the 16550 chip at 38.4KB with no trouble, using the
KA9Q NOS software.

Ideally, you'd like the computer-to-TNC link to run at a higher speed
than the radio link, so 19.2 is nice for a 9600 baud system.

The reason is that you have a PK-232MBX while the instructions are for
a PK-232. The ROM has changed. Now all you have to do is type KISS ON
and the PK-232MBX will go into kiss mode with default parameeters that
will work with NOS. Read the PK-232MBX manual.

This is a *different* problem. NOS has changed since the doc was written.
If you are using other than a 3 wire connection between the computer and
the TNC, IE SD, RD, Gnd, then you must assert DTR ON in the autoexec.nos
startup file. I don't have my notes handy, but it's a param command. Or,
do what I did and just change to a three wire cable.

With everybody updating their firmware and software faster than the
docs, these problems are inevitable.

Mea culpa. Yes, you need to add the parameters

param ax0 rts 1
param ax0 dtr 1

to your autoexec.net file anywhere after the attach command if your
TNC cares about the state of the RTS or DTR leads. And PK-232s *do*
care, as they use them for flow control. And if you want the PC to
obey the PK-232's flow control requests, add the 'c' parameter to the
end of the attach line, e.g.,

attach asy 0x3f8 4 slip com1 1500 1500 115200 c

BTW, NOS saves and restores modem control signals. That is, if they're
down when NOS starts and you raise them with the param commands, they'll
drop again when you exit NOS.

Subject: KA9Q NOS 911229 vs. shared COM? interrupts
To: [e-mail]

I just added a third COM port to my computer (an XT clone for these purposes),
only to find that NOS won't allow me to use COM1 and COM3 at the same time.
Specifically, COM3 won't work at all and COM1 operates very slowly (there is a
measurable delay between bytes sent out the serial port, although the bit rate
is correct).  When I use the ports individually from e.g. Telix, or enable
only one of the two from NOS, things work fine (that is, it's not something
specific about the port itself).

Is there anything that can be done about this, short of surgery on NOS's asy
driver?  I've been trying to avoid that because the local group runs a
customized split-screen NOS and the author won't distribute the source to his
changes.  On the other hand, I have some ideas of my own for it and therefore
might go ahead and hack the sources myself anyway.

In article <[e-mail]>, [e-mail] (Brandon S. Allbery KF8NH) asks about sharing com port IRQs:

I performed the surgery in question several months ago on my base
version of NOS. You can now specify "chaining" of IRQs; that is, a
device driver can be told to first service its interrupt and then jump
to the vector that was in place before the device was attached instead
of returning directly from the interrupt. If your hardware is properly
designed (i.e., the interrupt request lines are ORed together instead
of fighting directly for control of the bus IRQ line) this allows any
number of devices to share a single IRQ line.

Although the BIOS ROMs and/or DOS seem to be careful to install null
interrupt handlers for each vector at boot time, I didn't want to rely
on this.  Also, it takes time to call even a null interrupt service
routine, so this chaining behavior is NOT the default. To invoke
chaining, you have to append the letter "c" to the IRQ number on the
attach line in autoexec.net, e.g.,

attach asy 0x3f8 4c slip com1 1500 1500 115200

This tells the attach command to install the link to the interrupt
handler that was previously using IRQ 4. The device that is attached
last therefore gets control first when the interrupt comes, so keep
this in mind if you have devices of different speeds sharing an IRQ.

Shame on the guy who won't release the source to his NOS enhancements.
Perhaps a GNU-style copyleft for amateur use would be appropriate...

To: [e-mail]

Hi all,

I am interested in the discussions on 9k6 modems to fit into standard TNCs.
My TNC is a KPC-II, so I guess the first question must be whether this can take
an external modem.

Where can I get in touch with the manufacturers of a suitable external modem?
I am in the UK; I guess that the G6RUH(?) modem would be good if only because
the designer will be within reasonably easy access.  Or does anyone have any
better suggestions?

Thanks,

Hello:
 I have seen referances in this and other areas about the fact that
MSYS is supposed to not work properly when it come's to it's
handling of ax.25 and or netrom. My question is,

 1.  What really is broke and what symptoms exist on the air to prove
     that it is bad ?
 2.  Is there a particular set of circumstancses that can be repeated
     that make's it go bad ?
 3.  I see some strange things when my g8bpq switch trys to talk
     to MSYS, but how do I prove that's it's a MSYS internal problem or
     that it's not just some other problem (configuration or the like)?
 4.  Is it all versions of MSYS, or has it been fixed in some versions.

Sure it does. A crash-proof system requires all of those features
(preemptive scheduling, memory protection and resource management).
If I had only the latter two and my application goes into a tight
loop, everything stops. That's as good as a crash in my book.

Like I said, all of those features have their place. I recently bought
a copy of OS/2 because of its claimed ability to fully protect tasks
from each other, i.e., to avoid having to reboot the whole machine
when one application crashes. (I'll install it once I free up enough
disk space!!)

Full protection can be useful even if you're only running one
application. When you develop software on a machine with a $#@!!
Future Domain SCSI controller that takes the better part of an eon to
read the life history of every device on the bus at boot time, you get
real tired of hitting reset all the time...

Recently I had the pleasure of testing a pair of Codex "V.fast" dialup
modems. 24,000 bits/s on the line, up to 115,200 bits/sec (!)  on the
DTE interface. (A standard PC serial port can't go any faster than
that, as it corresponds to a baud rate generator divisor of 1!)

And they work, too, even on my 12 MHz 80286-based dedicated packet
switch. But the 16550A's are absolutely essential. NOS's FIFO high
water mark typically hits 13 when the DTE speed is set to 115,200 and
I do a FTP "get" operation.  That means an interrupt response time of
about 9 character times at 115,200 bits/sec (the chip is set to
interrupt when it gets 4 characters.) A standard 8250 or 16450 chip
would be hopeless here.

On rare occasions the high water mark hits 17, possibly because of a
long interrupt response time caused by being inside MS-DOS. Since the
FIFO is only 16 characters deep, I assume this can happen when a
character comes in after I've already started emptying the FIFO. I've
not seen *any* overruns, though.

A few corrections. You *have* to have a 9600 baud modem to do 9600 baud
packet. ( For the picky, you can use direct FM FSK with a Kantronics DVR
but you won't be compatible with anyone else.) You don't *have* to have a
TNC, there are plugin cards for the PC that do away with that necessity.
The low baudrate at HF is partially the result of regulation and partially
because of HF multipath fading. Faster transfer rates are possible, see
Clover II. 9600 is both legal and possible at VHF and above. It works fine
on 2 meters. Modems from PacComm, TAPR, G3RUH, K9NG, and Kantronics are all
available and interoperable.

The preferred TNC, if you use a TNC instead of a plugin card like the
Gracillis or Ottawa PI, is an original or clone TAPR TNC2. Examples
include the MFJ1270, MFJ1274, PacComm Tiny 2, and others. *Some* of
these TNCs need a slight modification to work at 9600 baud. The
opamp used for RS232 in the MFJ and TAPR units needs to be swapped
for a TL084, a faster direct plugin chip. The Tiny 2 needs a trace
cut and jumper to bring out the high speed serial clock. New Kantronics
TNCs support only their 9600 baud modem unless you want to do a lot of
hacking, but their modem works fine.

This is completely false. An original IBM PC can do 9600, or 19.2 kbaud
with a suitable interface card. If you are using an async port to talk
to a TNC, you must change the serial chip to a 16550AFN. If you are using
a Gracillis card, the DMA transfer method it uses works fine as is. Indeed,
the Gracillis card will work at 56 kilobaud, as will the Ottawa PI card.
The PC is not processor bound, after all the TNC does it with a little Z80.
The problem is IO interrupt latency on the IBM bus. That's cured by the DMA
approach or the 16 byte FIFO in the 16550 chip. This bus latency is a problem
with *all* IBM PCs and clones no matter what processor or clock rate they run
since the bus is maintained at a constant 8 MHz for compatibility. (Some
clones do run the bus at 11 MHz, but they won't work with all IBM cards.)

I have been experiencing a problem with the remote mailbox feature of KA9Q
NOS V920603. Quite simply, it does not seem to work. After receiving a
remote telnet session and receiving a valid login/password sequence, NET
displays the mailbox greeting, motd, but then locks up and sens no more
data. No prompt, no menu, nothing. The AX.25 mailbox is even worse: after
receiving a remote connect, NET sends absolutely no data to the distant
station. Manuals I have refer to and "mbox on" command, but this version of
NET chokes on it (i.e. returns the equivalent of a syntax error.). Outbound
AX.25 connects work fine, and as far as I know telnet seems to be working
ok. Any help at all would be appreciated.

The KPC II doesn't have the TAPR disconnect interface that most of the
9600 baud modems are designed to use. The Kantronics 9600 baud unit I
have is a daughter board designed to go in the DE56, or as in my case,
to attach to a Gracillis internal card. I don't know if a 9600 baud
modem is available for the KPC II from Kantronics. I suspect that
considerable hacking would be required to fit one of the other modems
to the KPC II.  Since Kantronics went their own way in TNC design, it's
sort of like trying to hack a Mac to take an IBM accessory board to get
the TAPR compatible modems to work. You can probably do it, but it's
likely much easier to just get a TAPR compatible TNC in the first place.
G3RUH's work is the basis for most of the 9600 baud modems. Some are
slightly better, and some are much worse. Kantronics' own 9600 baud
design is a derivative of the G3RUH design.

MSYS has bugs in its NET/ROM and IP handling.  I have seen AX.25 problems in
the past, but recent versions appear to have fixed them (after all, it's far
more likely run into those).

I haven't seen any symptoms in current versions, mainly because I hang out on
the IP frequencies these days and all the local MSYSes are on standard AX.25 /
NET/ROM frequencies.

NET/ROM:  the symptom I've seen is that it scotches packet flow control.

IP: the ones I've seen are:
    - flow control, as with NET/ROM
    - occasional-to-often checksum problems
    - there is at least one known case of a TCP packet with binary data
      (specifically, an LZ-compressed SMTP packet sent by a WNOS node)
      causing MSYS to crash

NET/ROM is best handled with MSYS by attaching a TNC with the NET/ROM, TheNET,
or other firmware to it (because NRS *does* work).  IP is best avoided.

I keep seeing people requesting information on mail gateways to amateur
radio packet, but as of yet I have not seen a single answer.  I have
heard rumors of a system called GRIP in Michigan that allows for IP
access to the U of M weather server among others, but I have not seen
anything from it in regards to whether or not it handles mail.

So I ask yet again:

    Are there any mail gateways from internet to packet out there?

NOS doesn't support shared interrupts. You should perform a bit of
surgery on your async card and grab an unused interrupt vector, the
LPT vector is a good candidate because DOS doesn't use the parallel
interrupt.

You have to do an explicit 'start ax25'.  This starts the ax25 mailbox
listener.  The command should probably be renamed to 'start mbox' although
there may be historical reasons for it being the way it is now.

Question for NOS wizards --

I have two PCs -- the main PC runs 24hrs, has a DRSI board, and is running
NOS.  I would like to hide this PC, remove its monitor, and control it
remotely from a second PC.  This second PC is connected via a serial line
to the first PC, and I have NOS running between the machines using a SLIP
connection.

Both machines have published IP addresses, but of course only one is connected
to a radio.  My problem is that when I initiate connections from the second
PC, routing through the first as a gateway, none of the returning packets
know to use the first as a gateway since it does not appear in their routing
tables. As a result I cannot connect.

Is there a way to force my main PC to intercept packets for my second PC's
IP address and forward them on?  Or some other feature of NOS that addresses
this situation?

Thanks in advance --

The gateways exist.  Not all of them forward e-mail from Internet to packet.
Most will forward packet mail to the Internet.  Almost all of them, except for
the mail-only gateways, link disconnected portions of AMPRNet (net-44,
ie. 44.x.x.x) using TCP/IP.  Roughly half of them allow digipeating of plain
AX.25 and Netrom packets to other gateways.  Some gateways allow
telnet(mailbox)/ftp access from the Internet.

At last count there were 24 gateways.  Two of them in Europe, four in
Australia, and the rest in Canada and the U.S.  And the list keeps growing.
I haven't kept any records but would guess that on average a new gateway
appears once a month.

Because of various concerns for security you will not find many of the gateway
administrators advertising their systems on Usenet.  However, the FAQs mention
a mailing list for gateways.  The mailing list is restricted to gateway
administrators, those who are planning on setting up gateways, and other
folks who have a 'need-to-know' (eg. FAQ editors).  To get onto the mailing
list, send a subscription request to [e-mail]
stating your name, callsign, and the nature of your interest (ie. one of the
three categories I mentioned above).  Subscribers are requested to keep
information from the gateways mailing list confidential.

Those interested in end-user access information may also send inquiries to the
address above.  Generally, the individual will then be directed to his/her
geographically nearest gateway for further questions by the administrator(s)
there.  Alternatively, one can send directly to the mailing list
([e-mail]) and hope that one of the sysops responds.  To
expedite the process, end-users should provide their full-name, callsign,
geographic location and a 'good' e-mail return address.  There is NO guarantee
of access to any of the gateways - just that someone (usually me) will try to
answer an inquiry as time permits.

Does anybody know what equipment I should but to get started in packet?
I would like something that is compatable with AX.25, CW, TCP/IP, can possibly be used portably
and can achieve speeds of 2400 or greater.  Also, where can one find about TCP/IP

Just as a general note, and not directed at anyone in particular:

If you're thinking about running OS/2, don't do this. While DOS doesn't use
the printer interrupt, OS/2 does, and (at least on an ISA machine) you can't
share interrupt levels between more than one piece of hardware.

BTW, this isn't restricted to COM ports; the default interrupt for the
Soundblaster card is IRQ 7, which is the same as LPT1:; a common problem for
new OS/2 users with Soundblasters is that they can't print...

There's not much you can do other than to comitt surgery on the
braindead design of an IBM PC.  The problem is 1/3 and 2/4 share
the same interrupt.  Any code that uses the interrupts (and most
PC code doesn't seem to) is going to have fun using 1/3 or 2/4
at the same time.

 Per Kantronics, none of the KPC line, or the KAM, are capable of

    One of my friends, WB4FQB (Ken Crump) is having troubke setting up
    a packet station.  He is using a new Kantronics All Mode TNC
    (ROM v5.2)attached to a new Gateway 386sx.  The combination works
    in terminal mode, but just stares at us in KISS mode or when
    using NOS.  We tried replacing the ROMS with v5.0 with no luck.
    Another Kantronics TNC (known good) was attached with the same
    results.  Assuming that the documentation is correct, the cables
    are wired correctly.  Swapping comm ports doesn't help.
    Long-time packet operator K4OLC (Lin Couch) is baffelled.

    If I sound dazed and confused, I am.  Waht I know about packet
    would fit in a very small thimble and still leave room for
    a finger.  Any thoughts or suggestions would be greatly appreciated.

thanks much...

This is not true.  Even if you do not have direct access to FTP you
can still use FTP.  Let me explain.  There are special servers out
there that accept FTP command files as e-mail and will execute the
command file for you.  One such site is "[e-mail]".

First you should send an e-mail with only "help" in the body of the
message.  It will then send you back a list of detailed instructions
on how to use it.

One note, for binary files you need to request the server to uuencode
it for you before sending it.  Then when you receive it you will need
to uudecode it back to a binary file.  This also means that you will
need the executable uudecode.  Check and see if you have this command
available at your site, if not then let me know and I will see what I
can do to get you a copy.

FTP mail servers are a blessing to those who only have e-mail access.
And they work pretty good.  There is some time delay and it's not as
neat as having real FTP access, but it makes a pretty good second.

Happy FTPing,

One way that would work is for your gateway PC to do an "arp publish" using
your hidden machines' IP address but the gateway's callsign.  Then when
some station arp's for your IP address, the gateway will respond, get the
packet, then figure out how to forward it to you.

If you have an application hang, you can always abort it. (System 7 has
