Subject: Interesting article in IEEE Comm Magazine
To: [e-mail]

People interested in applying spread spectrum techniques to packet
might check out IEEE Communications Magazine for Nov 1991.  There is
a useful article titled "Broadband CDMA for Personal Communications
Systems", in which some practical data on multipath is presented,
including some measurements in New York City (with non LOS paths!!).

In the same issue, there is a nice summary article "Mobile Radio:
An Overview".

                    Enjoy,

Dear Packet Radi:

Recently here in Gainesville, FL (Home of Fighting Florida Gators, playing
Notre Dame in the Sugar Bowl 1 January 1992) the DREAMSTATES BBS (FidoNet
1:3601/30) opened with much ado and fanfare offering various services
including UUCP/Internet connections and complete FidoNet communications
facilities. This DREAMSTATES BBS is hosted by Ray Hines, a noted and seasoned
professional in the operation of quality BBS'ing. Ray's DREAMSTATES BBS is
anchored by an AMIGA and serves IBM's and Mac's and Amigas, of all stripes.

Here in Gainesville we are also fortunate to have an avid and devoted band of
Ham Radio Operators.

I have asked Sysops Ray Hines to consider installing the "what ever it takes"
to offer to the Ham Radio community the telecommunications capability of
Packet Radio. Ray is open to further discussions but needs additional
information regarding such an undertaking.

Could I ask you to take a moment and send to me any information you may have
regarding the "what ever it takes" to install this packet capability. If you
know of any writing (s), files, manuals, etc. that might be of value, then I
would appreciate the references.

As I indicated, Ray is still in the exploratory stage seeking to quantify the
"what ever it takes".

Your kind consideration in this matter will be greatly appreciated.

This is the list from G3RUH users. There are big differences about the
performance at 9600 baud! The most of the direct pll phase modulator
radios are not very good at transmit. The problem is the phaseloop.
Current a group of oscar14 users are working on modifying phase modulated
pll radios. G3RUH has made a writeup about the phase modulator in
pll radio.
Best is an all-mode set. The most aren't using a phase modulator for FM.
But not all almode sets are good at 9600baud. (The FT736 9600 baud
receive results aren't very good.)

A very cheap Xtal oven is a PTC disk. In Europe we use mostly PTC disk's
from Siemens which are directly conected to the 12V. At startup they
take about 0.5Amp and this goes down after warmup. The trick to
solder the PTC fast to the Xtal, oterwhise you break the PTC disk.
(Broken PTC disk work also OK :-)
Sorry, I havn't the type number. I must lookup it at home.

No, not really.  You might check with the North Texas Microwave Society.
My understanding is that we often give the remaining copies of the
proceedings to the organization that sponsored the conference after a
couple of years.

I really don't think anyone would object to making these publications
available electronically once they are out of print.  My guess is that
anyine wanting to make them available for free could get permission
merely by asking for it (in writing).

Seems nlikely there is enough potential readership to interest such a
service in this material, but I'm sure the publications folks here at
HQ would be happy to discuss it with anyone interested in doing it.

Subject: KA9Q software and RTS assertion
To: [e-mail]

I'm trying to use the ka9q (or is it NOS) software to drive a
hame made (Baycomm) modem. I think that RTS should be asserted
to switch the radio into transmit. However the software only
turns it on when initially run and then off again at exit.
The source code seems not to contain statements to turn RTS
on and off at the appropriate moments.

The code seems relatively straightforward to modify. However, I'd
rather get it right first time instead of inconveniencing fellow
users of the Mellifluous Ether.

Does anyone have a mod for the appropriate file to fix this
problem?

thanks in advance

1) Start with those that use "true" FM (F3E), not phase modulation (PM - G3E).
2) Remember that PLL's don't like being told to change frequency.

Old all-mode rigs are good.  Even older xtal-locked rigs are better still.
I just don't understand why the black-box manufacturers persist in peddling
things that won't work on high-speed packet...  Notice how the "new breed"
of rigs are supposedly suitable for packet, yet are phase-modulated?

Subject: Packet at HF frequencies
To: [e-mail]

I am involved in a project to set up a digital radio link to a
university-chartered vessel operating 150-200 miles offshore.  The
system will have to use commercial HF SSB gear (150 W, international
marine HF frequencies)  The request I have for HAM folks is any suggestions
and/or experience with moderate (1200 baud) or higher speed TNC's
at HF frequencies.  I have heard nasty rumours about complications
due to fading channels and drifting transcievers.  (Presumably the
drift problem is at least minimized by using a good sythesized system)

One solution is a "Sky FAX" TNC from RACE technology in Vancouver
which uses eight parallel FSK frequencies and some pretty sexy error
detection/correction but it appears pricy (approx CDN$4800) and uses
a non-standard (non OSI) packet generation scheme.  As we would like,
in the long term, to be able to support relatively seamless ftp and mail
transfers between ship-board and shore-based computers, it would be nice
if the packet scheme was standard.

As we are currently involved in what is a point to point system at this
stage, digipeaters and networks are not an issue....but who knows where
it will go from there?

Thanks in advance

Subject: What radios will work w/ G3RUH modem ??
To: [e-mail]

I have not used a G3RUH modem myself, but have used a rather similar
commercial modem. The radio? Well, true FM (*NOT* Phase-modulation) is
whats needed. Phase-modulation cannot accurately represent the near-DC
components of the modulating signal.
You should try to bypass any stages in the radio that clip, limit or
alter the frequency-response of the signal. Ideally you feed the
'Audio' straight into the modulator, remembering that you must get the levels
right or you will have deviation problems. Also some ultimate frequency
restriction is a good idea if you want to remain popular with
other users of the band. An audio LPF is all thats needed.
On the receive side, you take the 'Audio' off the discriminator circuit
BEFORE the de-emphasis circuit has been allowed to screw around with
the signal.
Of course, this involves going inside the radio in many cases, but real
hams will have no worries about this. I have fitted a 15-pin 'D'
socket to quite a few of my radios, allowing direct access to the
modulator/discriminator for data, and leaving the normal mic. socket free
for speech modes. This is a good idea when searching for low BERs with
traditional 1200-baud packet too.

 Here's the rub-  I can't seem to connect to anyone!  I monitor my signal
 with another handheld and hear my signal going out, but not connect back.
 I found a friendly ham to connect with who CON'd to me.  My side sent me a
 connection message, but he never got it back.

 So it sounds like its a case of not being heard.  Is packet really critical
 about the signal?  I can make a repeater that is 75+ miles away on voice,
 but can't seem to make another packet station 10 miles away.  I did compare
 my packets (noise) to another stations and my signal was significantly
 quieter.

 Is there something about the Alinco I am missing.  The book only mentions
 another Alinco for hookup and says to use a .1uF cap and 33k Resistor.  Could
 this be my problem?  The rig is a new model- not in the PK88 book.

 Help!  Anyone who has any advice- I would surely appreciate it.  If you have
 Alinco hookup advice for packet- I'll take that too!

 Thanks for the anticipated solutions!

Off hand, I'd suggest that you are overdeviating.  Get the Alinco next to a
service monitor, and get the deviation checked.  I'd suggest that you keep it
< 4kHz for the high tone and < 3 kHz for the low tone.  DON'T make the
mistake of thinking they should be the same...

Good luck,

To: [e-mail]

Is anyone using an IC-2SAT HT on packet with a PK-88?  I haven't been
able to connect with any systems yet at 500mw through the rubber ducky.
That seems normal but when I switch to high power, and the TNC sends
a packet it doesn't drop the PTT.   My guess is that I am getting some
sort of feed back from the transmitter into the mic line.  Monitoring the
frequency shows it is transmitting silence.

    I have packet equipment very much like what you describe, i.e.
    an Icom IC-W2E (the Europe version), a short piece of coax and
    a GP antenna outside the window. It works very well even with
    low power.. 500 mW seems to be enough to have a contact with
    the local mailbox, though sometimes it seems to be just a bit
    too little. Taking it up to 1.5 W helps a lot.

    So, as an answer to your original question: yes, an IC-W2 can
    be used on packet.

Me too, it works fine here, but it is important to either leave the
squelch open (if you have true DCD) or turn off the power saver. In my
case the local mailbox is 100m away, so low power is enough. Connecting it
up to the beam on 70cms gave surprisingly good results with the 2 W output
(7.2 V battery pack).

Now I need a way of getting it to do dual band packet..........

Greetings.  I have a beta TNC from TAPR, and I also have a (borrowed)
Yaesu FT-203R HT.  I would really like to hook these things together.

------------------------------

Date: (null)
From: (null)
(1) Is the FT-203R keyed in the same way?  (I could probably check
    this.)

(2) Is the FT-203R also one of those doggone audio-returns-to-the-
    positive-bus things, like the FT-208?

BTW, in my TNC manual, they have a little section on hooking up an
FT-208.  It must have a 8-pin interface jack on it that the FT-203
doesn't have, or I could already have it hooked up.

I'm also sending a letter to TAPR asking them about this, but I
figured I might get a jump by posting... the radio has to be returned
to the school's ham club when I graduate in seven weeks, so every day
counts. :-)

Does anyone have any comments regarding DRSI's plug-in TNCs for IBM
compatibles?  Particularly the PCPA Type 1, which (if I understand
the literature correctly) is a 1200 baud VHF TNC with a serial port
for an external modem.

How do the DRSI TNCs compare with AEA's PK-88 (and its plug-in equivalent,
PCB-88)?

Any comments would be appreciated...Joakim

There is quite alot of 1200 baud packet around 28.195 mhz.  I have used it,
and it seems to work ok.

You might want to check AMTOR (Called SITOR in the maritime mobile service).
It is not even close to the speed you are looking for, but it is a
very reliable communications mode for HF.

could you elaborate on this?  a couple of years ago I was lent (and still have)
a tnc-1.  I connected it to my 2at and could monitor some folks but could
not connect.  I took it to a friendly packet type with a service monitor and
the deviation was measured as 4 khz on the high tone and 2 khz for the
low tone.   I was then told that I should have the same deviation for
both tones.  I'm confused.  I would like to get into packet and make use
of this TNC-1 sitting on my shelf but my experiences have been less
than favorable.  any suggestions?

prototype higher speed amateur network here in northern California.  I'm

>could you elaborate on this?

Normal FM as used by hams has a 6db per octave pre-emphasis applied;
since the higher tone used in packet is about twice the frequency of
the lower tone, you'd expect it to have about twice the deviation.

The trick is to set your radio and TNC up so that NEITHER tone is
running the radio into the clipper (modulation limiter).  Since most
voice radios are set to limit around 4.5 to 5.0 kHz peak deviation, by
setting the packet tone deviation to 3.5 to 4.0 kHz, you're pretty sure
you're not clipping and squaring off the modem tones.

Personally, I've set all my mountaintops to 3.5 kHz deviation on the
high tone to allow for slop in the users receivers.

To: [e-mail]

The calibration notes for TAPRs version 1.1.7b TNC-2 EPROM recommends a
frequency shift of 800 Hz as opposed to 1000 Hz on older TNCs.  The only
reason given is 'improved performance'.  The notes say the shift is compatible
with older TNCs running the 1000 Hz shift and so far I seem to have no trouble
talking to TNCs that I talked to before with the 1000 Hz shift.

Question:  What are the details behind this 'improved performance' by using
the 800 Hz shift?

Subject: PK-88 battery backup problem solved
To: [e-mail]

About a year ago I inherited a PK-88 that had problems with the battery
backup circuit.  I finally got around to troubleshooting it today.
Apparently there was an error at the factory during installation of
the original backup battery.  It was shorted out!  The mistake was an easy
one to make, since the correct teminal was about 1/16 inch away, and
not labeled clearly.

Has anyone else found similar factory wiring errors?  While it is possible
that the original owner caused the problem, I consider it unlikely.
He said he hadn't ever changed the battery, and just assumed that the
battery was old.  Also, the solder looked like the rest of the board, not
shiny like a hand-soldered joint.

Now my IP node will be able to recover from power outages completely
automatically, so it was worth the trouble to track down.

Happy New Year!

I found that having a lower deviation seemed to help when working
low-Earth-orbit satellites like MIR and the Space Shuttle.  My HT
can't QSY 3 Khz, so keeping the deviation low was the easiest way
to insure that I didn't pop out of the satellite's receive passband.
(Doppler shift causes the TX/RX to be translated up to 3.3 kHz on 2 meters!)

3.5 kHz deviation was pretty reliable for me.

Yeah, my buddy Dave (KD5RO) put one together, with me standing over him
watching...then I helped him figure out a few things with the software.
This is Dave's first experience with packet.  The software is slick!

Only weird thing I noticed is that the docs say, in several places, that
the modem is an AM7911...but they give you a standard AM7910.  I couldn't
get data on an AM7911, and I'm guessing that this is a misprint.  (I was
hoping it would be a 7911 with a DECENT carrier detect circuit!).

    I am not familiar with this kit but I assume that it is using the
    TCM 3105 modem IC and it is "stealing" its power from PC RS-232
    port.

>I'm mating the modem to a Zenith SuperSport laptop and
>a Yaesu FT-470.
    I have Zenith MiniSport and I had just the same problem. It appeared
    that the Motorola CMOS RS232 driver in Zenith could not drive enough
    current to the modem when transmitting. +5V pin in the modem chip went
    to abt +3V and it would not key the TX. Obvious solution is to get
    external power supply for the chip (I got it from the modem slot). Now
    it works fine.

You have two options to achcive this.  First one is Get the 3.06 firmware
upgrade from kantronics.  The new version of the firmware allows you to do
Software DCD instead of the normal sqeulch CD.  Second option is to get the
DCD kit with internal clock from TAPR.  It basically does the same thing
except you can't turn it off in the software, and its an extra lump in the
case.  I have the 3.06 Firmware in my KPC-2, and a TAPR DCD in my PK-88, and
I am completely satisfied with both systems.  It seems that the TAPR DCD
might be able figure out packets that the KPC-2 cannot, but that might be
a limitation of the TNC.

To: [e-mail]

An Australian distributor has recently made this short-form kit
available (PCB and EPROM), but the documentation is a little on the
sparse side...  Basically, there is a (hand-corrected) bill of
materials, and a (hand-corrected) barely-readable circuit diagram.

Apparently the device is capable of wondrous things, if only I had
further information!  What really piqued my interest was the on-board
"data transciever" (sic), and the circuit shows it as a little block,
with audio & PTT etc, and a little BNC connector on the side...  It
looks for all the world like the unit is part of some data engine or
other.

The ultra-fine print refers to the whole thing as a Pac-Comm EM-NB96
External FSK Modem, with other references on the PCB as "DFM-SA".  The
Bill of Materials is just a copy of a FAX from "NX2P Electronics" to
Pac-Comm.

Anyone have any further info on this beast?  NX2P, are you reading this?
A lot of people have ordered this kit, and some more info would be nice.

Can someone suggest a set of NOS parameters to start with for use in a
congested packet area (NE NJ).  I have started with the parameters that
came with my version of NOS (2.7 for the Amiga) and my throughput
compared to my TNC's AX.25 packet is horrible.  I have attempted to
transfer as many of the parameters as possible which are directly
translatable but I still have terrible throuhput.  My params in my TNC
have been optimized for my area and radio and would like a good starting
point to use for a congested area running NOS and TCP/IP.

According to the doc, the 7910 is for 'switched network applications' and
the 7911 is for 'leased-line, telex and voideo applications'. Basically it's
the same part, but there are some differences (7911 vs 7910):
- Reduced CD response time
- Reduced RTS to CTS response time
- Reduced squelch time for 1200bps modems
- Two new modes for bell 202 with 150bps backchannel
- three new modes for V23 with soft turn-off tone
- the V23 modes include 150bps backchannel
- The AM7911 supports CCITT R.20 for telex applications.

The CD detection times are:
     7910   7911
tCD(on)  18-22  3-7     ms
tCD(off) 12-23  3-11    ms
I can copy some doc if you are interested.

A side remark: I would suggest you build a fast noise squelch, as in
the HAPN 4800 baud modem. You could build the rest as well (all the parts
together are cheaper as one 7910!), and have a MUCH FASTER network.
7910 and 7911 (and TCM3105, for that matters) were never designed for
an CSMA network. They hold off CD even if they already recognized another
carrier, allowing your station to jump on that station and make another
collision!

You could build a sequencer (the TAPR board, for instance) but that gives
other problems: in our environment, HAPN 4800 baud modems share frequency
with antique bell 202 1200 baud modems. The sequencer squelch, however, does
not recognize 4800 baud signals and allows collisions over them.
Same goes for the Baycom thing..
Will this mean we will always stay at 1200 baud? I shure hope we don't,
if you ever worked at higher speeds you know why!

Subject: Looking for Macintosh packet software

I'm a relatively new packet user and a Macintosh diehard.  So I've been
looking for Macintosh packet software, of course.  The only problem is I
haven't been able to find any!  There was a message in this newsgroup
about a month ago suggesting that Mac users look in the ucsd.edu archive,
but I couldn't find anything there for the Mac.

So here's the question:  is there any Macintosh software for packet radio
out there?  I would be interested in public domain, shareware, or
commercial programs.  Are there Internet archives with Mac-specific
software?  What are good commercial sources?

I'm using a PacComm HandiPacket with a Kenwood HT.  For the time being,
I'm just using a generic terminal program on the Mac.  (I also have an
Atari Portfolio for portable packet operation.)

Any help you can offer will be much appreciated!

ucsd.edu has a few versions of NET/Mac, the Macintosh port of Phil Karn's
TCP/AX.25/NETROM packet software. (There is no Macintosh package based on
his later NOS software.) They're in the hamradio/packet/ka9q/net directory.

I use NET/Mac for all my packet activities, from transferring files on
the TCP/IP channel to reading DX callouts on the PacketCluster. The more
recent versions of NET/Mac have a separate window for each different
session; even the earlier ones have separate console, trace, and log
windows, which is very helpful.


Patty

p.s. Although it won't do you any good, I understand that AEA offers
multimode Macintosh software (packet, RTTY, etc.) for their PK-232 TNCs.

It's finally happening - we are putting up a regenerative repeater
using G3RUH modems. Before we get started I would appreciate any
hints/suggestions/caveats from any of you who have already done
so.

I apologize for the attempt to respond to this a few days ago that only
succeeded in echoing the original message, I goofed...

I use the N4PLK Baycom modem successfully with a KayPro 2000 laptop.
The serial port did not provide enough juice to power the modem,
however. The KayPro uses a 6 volt battery charged by a nominal 7.3 volt
power supply; the RS-232 signals at the serial port do not go positive
enough to feed the 78L05 regulator on the modem board.

Another solution was available with one of my 2 meter rigs, a KDK 2016
-- the auxiliary jack at the back provides access to 12 volts d.c. as
well as to the audio and mic and ptt lines. See if that is an option with
your 2 meter rig.
Another option -- use a 9 volt battery. The N4PLK modem will work fine
with a 9 volt supply.

If you need it for a PC, then you may be able to use BPQ to provide a DED
host mode. It involves running the TNC in KISS mode, configuring the BPQ
switch (reasonably straight forward), and using the dedhost.com
driver. The application interface to dedhost.com is a combios like.

  The latest release of BPQ that I am aware of is 4.04 July 1991. Does
anyone know/have a later version?

You can run the PK-88 in KISS mode.  Then run G8BPQ to emulate the DED host
mode.

Baycom vs PMP:

Software: Baycom's packet assembler/disassembler is a Terminate and Stay
Resident (TSR) program. You can shell out to DOS and leave the TSR
active while you do something else. It uses a lot of memory, though, so
you can't run a big program. PMP is a single program.

Interface: Baycom is much more sophisticated, almost a full-service
packet system. PMP is much simpler. Parameters can be changed at any
time in Baycom, with PMP you have to stop the program and change the
config file, then start up again.  Baycom has a lot more commands than
PMP.

Documentation: PMP comes with source code; Baycom is a big secret.
PMP's documentation is clear, Baycom's from the German translated is.
(Although version 1.4 docs are much better than vers. 1.2). PMP's
authors are reachable on the Internet. It took six months after I
mailed my registration to Germany to get a disk back with the new
version of Baycom, and there was no response to the questions I had
asked in my letter.

Hardware: The modems are not quite functionally identical. I have a
TCM3105 modem from the PMP authors and a Baycom TCM3105 version from
N4PLK. The PMP modem supplies a carrier detect signal to the computer,
Baycom's software apparently just senses data coming in. The Baycom
modem has to connect to serial port RS232 lines with higher, bipolar
voltages; the N4PLK modem isolates the modem chip with 74HC04 buffers
so the program must be dealing with inverted signals relative to the
PMP program. The PMP modem connects to TTL level signals at a parallel
port. It would be a service if someone would design a modem compatible
with both systems; it could be done with a few extra parts and some
jumpers. One version of the PMP modem has a watchdog circuit that
prevents accidentally keying the transceiver when the program is not
active. This accidental keying was a problem for me with Baycom, I had
to remember to disconnect the modem from the computer or turn off the
transceiver when using the computer for other purposes.

Power requirements: both modems can get power from a serial port. (Note
this would tie up both serial and parallel ports with PMP). This did not
work on my own laptop, which has relatively low RS232 voltages. In my
case I was able to get 12 volts from the 2 meter transceiver. A 9 volt
battery will work also. Either modem can be built compactly enough to
fit into a DB25 shell.

On the horizon: The German authors of Baycom refer in the documentation
to a hardware package that will go with the software and support many
more features, including multiple baud rates. I have seen no information
on availability of this hardware in the US, and I don't know if it is
beyond the prototype stage in Europe.  The software version has commands
to support 300 baud, but I don't know if it will actually work. The TCM
3105 modem chip can not be made to work at 300 baud in the proper data
format. The PMP authors did not try to include any 300 baud support;
they say it would require a 7910 type modem and they thought the higher
power consumption was not compatible with their other system requirements.
    The Germans indicate they are doing further development, we'll
have to wait and see what happens. Since the workings of the software
are a secret, nobody else can do much along these lines. Since source
code is provided for PMP I would expect improvements could come from
all over the place once people start attacking the problems.

Conclusions: Either system is an effective way to get going. Baycom is
more elegant and complete. Both systems may not work with all computers,
as they depend on using serial and parallel ports in non-standard ways.
N4PLK offered to refund the cost of his modem (when purchased assembled
and tested) if it was found to be incompatible. I don't know if that
offer still stands, it was made last spring when he first started
marketing the device. In some cases the incompatibility may be simply
the inadequacy of the serial port as a source of power.
    PMP is a better way to go if you are enough of a C programmer
that you could think of implementing your own improvements. Baycom has
more features but is a black box inside.
    I have used Baycom on and off for more than 6 months, and I am
beginning to see messages on packet BBSs indicating there is a
community of users out there. I have only experimented a little with
PMP, enough to know it also works. PMP got a later start, but I have
seen some messages about it, too. I would expect some kind of users
groups to form, but I haven't heard of any yet. Maybe someone will
respond to this message with some info on that.

The New Jersey State Senate approved the new scanner bill S-305 today.
The New Jersey State Assembly had previously passed this bill last
Wednesday.  The Governor is expected to view the bill favorably and
will probably sign it into law in the next week.  I don't have the
information on the effective date, but it will be soon.

This law replaces the existing statute which makes it a crime to
carry any scanner or radio capable of receiving police, fire et al
communications in a vehicle.  This makes it difficult for Radio Amateurs
to have modern radios in their cars due to the extended coverage
that they provide.

The new law makes it a crime to possess a scanner while committing, or
attempting to commit, another crime anywhere in the state.  Law-abiding
citizens will be free to enjoy free access to communications while
the criminals will be at increased risk.

[ Is there a FAQ for this sort of question? ]

A mate of mine is having trouble getting the Alinco 560 dual-band
to work on packet.  He says the transmitted audio, when monitored on
another receiver, sounds way down in level, but is known to work with
another transceiver.

Is there anything "special" about the microphone circuit?  I questioned him
about the rig (I've never seen it) and he says the spkr/mic socket uses
separate connections for the mic and the PTT (it's a 2.5mm stereo socket,
with a separate 3.5mm socket for the speaker) which is not what I would
have expected - most hand-helds these days "double up" on the mic/PTT in
many and various ways.

So, what to look for?

This should probably be a FAQ entry.

NET (now NOS) began life in late 1985 on an old Xerox 820.  I bought a
PC-XT clone shortly thereafter and gave up on CP/M and the 820
forever.  (The 820s finally got donated to the local high school
electronics lab back in NJ shortly before I moved to San Diego last
July. Maybe they can use the power supplies for something.)  The code
has advanced so far beyond its humble CP/M beginnings that even if I
could figure out a way to read all those old 8" floppies in my garage,
you wouldn't want it.  You'd be better off hacking the current code to
fit, or better yet, going out and buying a cheap PC to run the
existing code. Stripped PCs capable of running NOS just don't cost
that much anymore!

Subject: K9NG modem modifications
To: [e-mail]

To summarize my mods to the K9NG modem:

Data-derived RX Clock may be derived from U4 pin 9.

Half an LS02 can be used to buffer and gate RXD and RXC with DCD/, which
will really cut down on the number of frame aborts in the switch or TNC.

R31 should be changed to 0 ohms, and C18 should be increased to .1 uF
to improve the DCD circuit.  Cuts down on chattering.

If you don't have a 16x or 32x clock available, a 4060 and a 4.9152MHz
crystal will get you one for about $3 total.

At 4800 bps, no changes are needed to the input RCV Filter, but at 9600
bps, the capacitor values are quite critical because the low-pass filter
cutoff is too close to 4800 Hz.  If your radio has a decent IF, you can
just cut the values down and you'll get fewer damaged received packets.
(In fact, what I do is reduce C13/14 from a parallel combination of
2700 and 1800 pf to just the 2700 pf, and use the single 1800 pf
left over instead of C15/16, which used to be 2200pf + 56pf.)

Change C19, a 220uF capacitor, to something like 6uF to avoid frying
the regulator.

For a TNC-2, jumper the modem header pin 3 to pin 4 so that Net/Rom
can find itself.  Don't cut the jumper on 9-10, so that the keying
circuit inside the TNC will continue to work.  Do cut the jumper on 7-8.
Putting a jumper across 1-2 will let the DCD light on the TNC work.

Hanging a diode from U2 pin 6 to the RTS/ line (solder it from the
right-hand side of R26 to the right-hand side of D3) will inhibit the
DCD/ output while you're transmitting, which might confuse things.
Note that because of the hang time of the DCD circuit, you WILL get a
brief burst of DCD after you unkey, but that's unlikely to cause any
problems even in a critical device driver, since you will have already
told the interface to deassert RTS/, and presumably you're therefore
ready for incoming carriers.

Oh, and of course you can leave out all the stuff after U6 pin 10 and
U2 pin 14.  That's all just DC switching stuff that you won't need if
you're using the TNC's PTT or some external PTT.  If you are using the
modem without a TNC, you can use U6 pin 10 to drive a transistor, or
a 555 and a transistor if you need a blab-off.

To turn the modem into an FSK regenerator for real-time digital
repeating, cut the trace from U7-1 to U8-13, and connect U7-1 to U2-2.
That will push received data up the transmit modulation channel whenever
RTS/ is not asserted.

avoid anything with relays in it.  Also, a synthesized rig may be worth the
extra $$.  Remember to consider the price of crystals when you are looking
at a rock bound rig (about $10-14  a pair).

To: [e-mail]

I have been able to carry on several good PBBS
QSOs using an Icom W2A, a ProComm Handipacket,
and a Toshiba 1000SE using a dumb terminal
program and cables supplied by ProComm.

The volume knob for the appropriate band needs
to be at about 90 degrees clockwise of "off,"
the battery save ratio needs to be OFF and the
squelch setting is pretty inconsequential.

This setup msetup makkes a ompact battery
operated package; it might be considered for
emergency BBS traffic.

Subject: Baycom Questions
To: [e-mail]

I finally pulled out the baycom circuit that I started some time
ago, and got it limping along (only works with a scope probe
conntected to the CTS signal, recieve line).

But I was reading some of the docs and it mentions that there
is 2 mailbox formats built in.  Does anyone know if these are
compatable with the standard mailboxs used here in the US?

Also, when my computer boots up, the RS232 signals to port 1
are not initialized, and the internal 5v source (I had to use
a 5.1 volt zener because I had only 6.5 volts available thru
the diodes from the port) drops to -.46 volts (reverse zener diode
drop).  So far this hasn't hurt the TC3105 chip.  Does anyone know
if this is a real problem?

Some questions about interfacing the K9NG modems:

1.  Does anyone know how to connect a K9NG or G3RUH modem to any of the
following radios?

Wilson T-1405 SM
Yaesu FT-207
Kenwood TR-7400A
ICOM IC-3200A


2.  Has anyone come up with a generic circuit that generates an FM signal
from a K9NG/G3RUH modem at some intermediate frequency (user-settable of
course)?  The resulting signal could then be injected into the mixer of a radio
through a pot and coupling capacitor.  I know the WA4DSY modem already does
this but I'm looking for something that can talk at 9600 BAUD to other
K9NG/G3RUH modems.

Subject: AA4RE problems/questions
To: [e-mail]

A guy in our club is running aa AA4RE PBBS and is trying to implement the
dial-in port. He's using an internal 2400bps modem but is having problems
with it. It works fine when dialing out but when dialing in, the call
appears to never be answered. On the system side, it appears that the call
is answered but hung up almost immediately, so fast that the caller is not
aware of it. With other software instead of the AA4RE package, such as
QMODEM or Procomm, the modem works fine. I suspect there is a delay
parameter that is not correctly set in the AA4RE package but we can't find
anything in the documentation to support that.

Does anyone have any suggestions? Any help will be greatly appreciated.

Subject: solar emergency power
To: [e-mail]

Attention Amateurs with an interest in solar/emergency
power for their rigs!  A potentially great deal just came
in the current Damark "remainders" catalog today:

"Solar-Powered Patio Light" (p. 12)

contains:

10 watt solar panel 1 x 3 ft
72 watt/h lead acid gel battery
plus a 7 watt PL light and mounting hardware
has remote and auto-on modes


The voltages weren't specified, nor did
it say whether the battery is diode-protected
or not, but assuming the components have a
reasonable lifetime, the price of $69.99 plus
$12 s/h per unit is pretty damn good.  Since
the unit is designed to live outdoors, the
components are probably somewhat sturdier
and better protected than units intended otherwise.

I might pay the same price alone for an extra
battery for my HT that has 1/10 the mAh rating
of the gel cell alone; the solar panel and the
claimed 40-w equivalent light and hardware are "free."

I ordered two of them (I have no idea if the units
are good quality or not, but at least Damark has a
30-day warranty: beats "as-is" hamfest stuff).

I figure with two units I can perpetually keep
my HT/TNC on the air on a 500mw setting, assuming
a 1 minute xmit, 1 minute rx, and 8 minutes
standing by duty cycle, as well as run my notebook
for several hours a day.

If you are interested, the item number is
B-484-2000390 in the Feb 92 Damark
catalog: 1-800-729-9000 24h/7 days.

[Usual disclaimers: plus, if the units are garbage,
the only satisfaction you'll get from me is knowing
I got burned with _two_ units. :-)]

To: [e-mail]

As someone pointed out a few days ago, the executable for AmigaNOS 2.8m
is now available on ucsd.edu ("/hamradio/incoming/amiga/amiganos2.8m) ,
I believe.

I would like to rewrite amiganos2.8m so that elm is called instead of
the rather braindead bbs program.  Could someone  that has the source
code for amiganos2.8m (Ie. G1YYH) please upload it to ucsd.edu, or tell me where
else I can obtain it from?  If G1YYH is subscribed to this listserv,
could you please also tell me  if any releases past version 2.8m are
planned to be release soon?

Thanks,

   I looked at the GE MVP service manual last night. The transmit PTT
circuit allows a 20 mS delay for the T/R relay to switch before starting
the transmitter up. I suspect this is conservative, that the relay is
even faster (10-15 mS). I suspect the oscillator startup time is maybe
20 mS; the overall transmit delay for this old relay switched radio
is about 40 mS; this is maybe 4 times faster than a common PLL
synthesized radio.

  So? Don't be afraid of relays. Be more afraid of PLL synthesizers.
What is the *real* problem with a long transmit delay, anyway?

  Simple: from the time your TNC decides the channel is clear and
activates PTT until the transmitter actually emits a coherent signal,
you are prone to a collision with another station. Rather like hidden
transmitter syndrome, in this case the transmitter is hidden behind
the time delay for the PLL synthesizer to settle down. Every station
can hear every other station perfectly, but you'll still have collisions
if it takes a long time to capture the channel.

Subject: 1200 vs. 2400
To: [e-mail]

In an effort to "wean" people away from 1200 bps operation, I'm thinking
of establishing a 2400 bps port on our BBS.  These upgrades are readily
available, and require no special connections to the radio.  As an aside,
I'm pleased that the various manufacturers seem to use the same modulation
technique - they probably all use the same modem chip I guess.  I realise
there are "chicken and egg" issues here, in that there's not much point in
providing a service if it gets little use, bt I'll take that risk.

Anyway, how compatible are the two modes?  Can they co-exist on the one
channel (permitting me to use a common transceiver), or won't they "see"
each other?  I'm trying to avoid using "squelch" carrier-detect, in favour
of modem energy or bit-transition.

Note for Australian readers: what would be a good channel to use, to establish
a "de-facto" standard in the event the modes are incompatible?  Most of the
channels are "flat out" with 1200 operation, with some 4800 work on 144.800.

Note for non-Australian readers: I realise that Australia is quite backward
in packet operation, due to ossified thinking, but some of us are trying to
do something about it.  Those 1200 bps "network links" are a joke!!!  As
for 56k bps operation etc, don't even ask...

At least two hams are using PLL rigs and doing quite well :-) and they
don't have to buy endless pairs of expensive rocks every time the
local "evil C-word" group changes their mind.  1200 baud Bell 202 AFSK
is just not that critical, considering that it's inherently flawed.

Not all PLL's are as slow as you seem to indicate.  My Icom 290H (PLL
PIN diode switched multimode) works just fine at TXD 3 (30 mS), which
is as fast as we've been able to get any rig - rockbounders included.
In fact, _some_ crystal controlled rigs are absolutely pathetic
regarding TR turnaround time.

The absolute here is that there ain't no absolutes.

It's not good to run txdelay at the minimum, though - the rigs need
time to stabilize (on both ends), and the BER suffers if you cut it
too close.  A bit error is every bit as bad as a collision.

We've found that TXD 10 at 9600 baud, and txd 30 to 40 at 1200, seems
to work best with most stations, and the extra TXD does not contribute
to collisions.  Remember - even though you're not broadcasting "data",
you're broadcasting a signal that will activate DCD, or in the case of
1200 baud non-MFJ modems, will activate the noise detector electro-
junk they laughably call "DCD".

.. and I don't want to hear about Kantronics "software CD" - I wasted
$30 on v3.0 ROMs to get that feature.  It works - in fact, so well
that some competing TNC's are not heard!  Cheap shot.  I've since
turned that abomination off and reinstalled my TAPR DCD state machine.

You're right about relays - unless you mute them with marshmallows,
they won't make more than txd 1 worth of difference - and I'm
grudgingly conceding that!  Just because they're mechanical doesn't
make them ridiculous.  I still use relays in some of my designs.
They're much more forgiving of indiscretions.  However, XYL's have
expressed a definite preference for PIN diodes over relays at 3 AM
when the local insomniac is banging away at your station.

I like it, go for it .. it would be nicer if RWI functioned as a network
gateway though, so that 2400bps users would have something else to do,
unless you yourself would be willing to take on such a role :-)

We don't appear to have any great problems running HAPN-4800's and 1200's
on the same channel. Mail Paul 2AQG, he runs them both on 144.8MHz

hmm, and 1200 too, much to my chagrin. I could suggest a frequency, but it'd
boild down to one I don't use :-) Why not use 144.850 ? It can't be that
busy surely ?

Subject: Drake TR22C For Packet
To: [e-mail]

I just picked up a TR22C and a TR33C for a whopping $40. My plan is
to use the TR22C as a packet station since it has adequate power to
hit the local BBS that I use. I don't have the manual for the TR22,
but the TR33 states a frequency range of 146-148. Since both are
crystal controlled, am I going to have a problem running the 22 at
144.93?

Also, does the TR22 have sufficient TX turnaround to be a reasonable
packet station?

Way back in 1983 or so, I was one of the first packet stations on the
air in NNJ, and I used a TR22C. I did have to modify the receiver to
reduce the T-to-R recovery time. As I recall, a voltage was injected
into the squelch detector circuit while in transmit to ensure that the
audio output stages were muted. It took a long time (hundreds of
milliseconds) for this voltage to decay after switching back to
receive.

Clipping the wire that injected the transmit voltage resulted in a
very fast receiver recovery time. It also caused the radio to receive
its own transmissions, but this didn't cause any problems. (Just don't
try to use the radio for voice, or if you do, turn down the AF gain
before transmitting to avoid feedback.)

Many other radios have similarly long receiver recovery times, and
they can often be fixed in similar ways.

Subject: Establishing an Internet Packet Radio Gateway.
To: [e-mail]

Hello.

I am interested in getting into amateur radio, particularly in hooking up
HAM equipment to a computer, and having access to Internet.  I found your
'address' in an Internet resource guide, and in the comments it specified
that your address is geared to the promotion of packet radio.

Currently, in my search for a public access site into the Internet, I have
been spending quite a lot of money; I've contacted sites in California,
Massachusetts, and several other places, causing my long distance bills to
become quite a liability!  I'm now using a site in Ottawa, still a good
distance (in terms of money) from me.  It seems the only way I'm going to
enjoy low-cost or no-cost access to the Internet in this area of Canada is
to do it with a HAM setup.

I have the opportunity to purchase some old HAM equipment at what appears to
be a reasonable cost...but, like I said, it's old (vacuum tube technology).
Do you think that a setup like this would be adequate for computer linkup,
or would I experience much drift from not having electronic tuners?  What
kinds of methods are used to hook the radio to the computer?  How does one
actually reach another node?  Also, I am an apartment dweller; how far can
you go with a balcony antenna?  What kind of licence is required, etc...

I have an Intel 80386SX @ 16MHz with 120 MEG of hard disk space, VGA, as
well as an old 8088 XT with 20 MEG of hard disk space connected to the
386 via the Lantastic LAN cards from Artisoft.

What I'm interested in doing is primarily e-mail, however I'd be *very* keen
on doing FTP/telnet, newsfeeds, and Inter-Relay Chat as well, provided that
was possible.

I haven't had much luck finding people who have hooked their computers up
to the Internet via HAM and TCP/IP; so you can imagine I'm pretty naive
about this subject at the moment.  From the people I have talked to, I have
received disturbing replies such as, "It is illegal to use HAM for purposes
of evading phone toll-charges" and "Although Packet Radio can be used to
transmit data, it is illegal to operate a gateway".  I'm not convinced,
there is clear evidence of these gateways in operation (otherwise I would
not have been successful reaching you)!  Could you please send me any
information you think I might require?

Thanks in advance,

Steve Frampton

  Why avoid anything with relays in it? Because they make noise? Because
the result in longer transmit delay times? I'll take relays over PLL
synthesizers any day of the week. I don't think radios with relay T/R
switches are that slow, anyway.

  For packet, I would strongly suggest avoiding a synthesized radio.
Very strongly. Most synthesized radios require more than 100 mS for
transmit delay time. My Kenwood TR-2600A HT requires about 150 mS from
the time PTT is active until RF starts coming out of the antenna connector.
A crystal radio is much faster. My old TR-22 requires maybe 20 mS from PTT
to have full RF. This 20 mS represents the time it takes the 12 Mhz xtal
oscillator to start up. If a radio is relay switched, my guess is that
the relay switches and the oscillator starts up in parallel; i.e., it
really doesn't hurt to have a relay switched radio. Also, synthesized
radios usually require a fairly long time for the receiver to start
working after transmitting; this is a killer for throughout.

Note: My TR-22 receiver is quite poor, with poor sensitivity and poor
      intermodulation characteristics and poor overload characteristics.
      I only use it cause it is convienent. I plan to replace it soon
      with a much superior radio.

  To get started, you will want a synthesized radio to find out which
frequencies have the most activity. If you're like me, you'll find that
a few frequencies are active. Buy crystals for those channels and
put them in a good crystal radio, and dedicate that radio to packet.
Use the synthesized radio for chatting about the no-code license :-).

  I'd recommend buying a surplus commercial radio for packet. Like a
GE Mastr, GE MVP, Motorola Micor, Mitrek, etc. Be sure to get one
that covers your band of interest; Micors, for instance, come in 138-150
and 150-174 Mhz flavors. It is really a hassle to convert a 150-174 radio
to 2m; most people can't do it. Look for these kinds of radios at swap
meets. Haggle on the price. Basically, you want to pay as little as
possible for them. The GE MVP is attractive because it is a one
piece unit, while most of the others are control head/radio combos.
You often don't need a control head for packet. Look for radios that
offer multiple channels. Disable the CTCSS options if they are
present. Consider taking the packet output directly from the discriminator
output if possible.

  Besides being cheap, the commercial gear is built like tanks. Very
rugged. The receivers are often moderately sensitive, but exceptionally
immune to intermodulation and overload. They make the modern stuff
look stupid in terms of selectivity and overload performance. Put a
good GaAs FET preamp on a commercial radio, and it will kick tail
on any amateur gear.

Ahhh...  I was wondering why my KPC-2400 could dig some signals out of

fiddling with the "SWP" command some more.

I have had a couple of relays "gum up" on me though.  Not the antenna
change-over, but the Rx/Tx supply - I guess the contacts don't carry
enough "wetting" current to keep them clean.  If it keeps up, I'll put
in some sort of a transistor switch.

Subject : Re: Need advice on VHF XCVR


Synthesized radios do not *necessarily* have long T/R switching times;
it depends on the design. Many FM-only radios program their PLL
synthesizers to produce signals that can be multiplied to the first LO
frequency in receive mode (channel frequency +/- 1st IF). In transmit,
the synthesizers are swung up or down by the 1st IF (typically 10.7
MHz), FMed by transmitted voice (usually by direct injection into the
VCO control line) and then multiplied to the channel frequency. It's
this shift in PLL frequency between transmit and receive that can
cause the radios to take a while to key up or to recover their
receivers.

But some radios (notably most all-mode rigs) leave the PLL alone.
Since they generate their transmit signals at IF and heterodyne them
up to the channel frequency, there is no need for a "swinging"
synthesizer.

One sometimes reliable way to tell if you have a radio that swings its
synthesizer PLL between transmit and receive is to key it up while
closely listening to it on another FM receiver.  If you hear a
"Pingggg....." sound at keyup, chances are your radio does indeed
swing its PLL, and it may have problems keying up rapidly enough for
packet use. The "ping" is the PLL's dynamic response to the step
function that is applied to its loop when it is switched to the
transmit mode.

One of these days we'll have DDS (direct digital synthesis) in all our
radios and this problem will go away...

Take a look at 4800 baud as well.  It's not that hard and worth

Hmmm.  It changes in each place.  Most of the whole 2m band is
deathly quiet here in the ACT :-( however it's quite busy in
Sydney.  You'd have to use one of the "packet allocation"
frequencies at 144 Mhz, something like 144.750 or something.

<sigh>  1200 baud UHF links using ROSE is the joke. :-(  We have
a small 4800 baud NET/ROM network operational as well, Dave.
Hopefully Sydney/Melbourne Connectivity sometime in the next few
months.  (It'll be slow though, most of it will be at 1200 baud.)

An Amateur Radio <-> Internet gateway is very unlikely, for several reasons:

    1. You cannot transmit "obscenities" over the air, making most
       netnews non-transferrable.

    2. You can't transmit crypted/cyphered messages, making a "batch"
       newsfeed, FTP transfer, etc., a "no-no" on the AR bands.

    3. A control operator must inspect each message before it is sent
       (for reason #1) thus making inbound e-mail sorta hard to get,
       unless the control operator of the sending site reads all your
       e-mail.

Could someone post the U5MIR-1 frequency data for packet?  I heard U4MIR on 145.55

Dave, the frequency for packet is also 145.550. Aparently, they are mostly
on packet, but ocassionaly can be heard on voice..

By the way, a good satellite tracker such as TRAKSAT really helps. I loaded
up the most recent 2-line element sets from NORAD and was able to hear
MIR within a minute or so of the predicted time of signal acquisition..

Also, has anyone heard anything about how long U5MIR will be on the air.
Someone mentioned that there may not be any hams on board in a few months.
Anyone know about this?

    NOS stands for Network Operating System. It is rather complex
piece of software started by Phil Karn (ka9q) to allow TCP/IP networking
on the amatuer packet network. (I'm sure others will expand on various
points on this ;-).

    The 'average' packeteer would probably be overwelmed by MOST of
the features in NOS. However, if your interested in doing something with
your packet station besides keyboard-to-keyboard or BBS'ing then you
might want to give it a try.

    BEWARE! It's NOT for the faint hearted. But it can sure be FUN!!

Here you go:




Instructions for the W2XO packet/internet gateway.

To mail from Internet to Packet:
    1. Mail to: "[e-mail]"
    2. Make the first line of the text a packet bbs "send" command, ie;
    SP TOCALL @ BBSCALL < FROMCALL
    3. The "subject" line of the internet mail becomes the "title"
    line of the packet mail.

To mail from Packet to Internet:
    1. I must have the ham call in my gateway alias list. If you
    want to mail to a specific ham via the internet, send
    me mail with his/her call and internet address.
    2. Once (1) above is accomplished, all that is necessary
    is to send packet mail to CALL @ W2XO.#WPA.PA.USA.NOAM .
    The mail will automatically be forwarded to the internet
    address of the ham whose call this is.


Hope this helps!

Hello,

I am not on packet, but  would like to be able to send mail to a friend
N3CWG at the K3PZN bbs. I believe the address is [e-mail]

Could someone please describe how to send email there using one of the
internet <-> packet 'wormholes' ? I don't suppose this would be of general
interest to the group, so email is encouraged.

Also, on a semi-related topic, if I cannot get through on packet, he has
an account on compuserve of 72571,3437. Does anyone know if I can send an
email message to him there ? From what name servers are telling me,
compuserve is on the net, but I'm at a loss as to how to specify the
userid.. has anyone done this ?

Thanks for your time.

  1200 baud is inherently flawed? Huh? How? It works for me. Just cause
it isn't 9600 baud doesn't make it broken, at least not to impartial
observer.

   Sure, even my lousy TR-22 was slow to return to receive from transmit
until I buggered the power supply to leave the receiver running while
transmitting. However, as a *general* rule, which is what I presented,
PLL rigs tend to be quite slow to turnaround in either direction.

  However, I've noticed many multi-mode radios turn around very quickly.
Maybe this is because they want to be able to offer reasonable CW
performance, for semi or full break-in keying.. who knows? The average
radio on 2m, that is a PLL FM-only rig, tends to be slow.

    Nothing like clarifying an issue with a sage observation.

    Strictly speaking, I don't think I'd classify a frame lost
due to insufficient TXD as a 'BER' problem; sure, you can use the
term, but it is misleading. 'Bit Error Rate' implies the maximum
performance of the link under steady conditions, at least to me.
However, you are correct that insufficient TXD results in lost
frames. But, a frame lost due to short TXD is not as bad as a collision;
since the frame was being transmitted, the channel stayed busy, and only
one station has to retry. With a collision, it is possible for two (or more)
stations to retry...

  Electrojunk? Excuse me. My PK-88 has a TAPR State Machine in it... is
that junk? Hmmm? Anyway, you've completely missed the point about
TXD; I'm not talking about emitting a lone, useless idle sequence;
I'm talking about a radio which goes deaf and does not start transmitting
for 100-200 mS; this window allows collisions.

    Most relays I've seen are worth 20 mS (or TXD 2) of delay.
Why is your XYL sleeping in the shack? Mine sleeps in bed with me

 I was wondering if this AmigaNOS would be of any use over a null-modem
connection? Basically I'm looking to connect two 500's to a 2500 via
null-modem so that they can access files/programs. (Yer basic network
task). I've attempted DNet with no success (It can only do a hookup
anyways) so would AmigaNOS be a possible answer?

   An Amateur Radio <-> Internet gateway is very unlikely, for several reasons:

       2. You can't transmit crypted/cyphered messages, making a "batch"
          newsfeed, FTP transfer, etc., a "no-no" on the AR bands.

I do FTPs over the air all the time.  I think you are thinking that
compressed data is not legal.  I think that compressed data is just
binary data and should be legal, unless it really is encrypted as is
possible with many archive programs.

       3. A control operator must inspect each message before it is sent
          (for reason #1) thus making inbound e-mail sorta hard to get,
          unless the control operator of the sending site reads all your
          e-mail.

this is not really a legal must as it is a practical must.  you can
allow unattended station operation but when 3rd party non amateur
stuff is going out on the air it is the gateway owner's call that is
on it and who is responsible.    it is to his/her advantage to inspect
stuff before it goes out.

This is a common question that is in the FAQ.  The standard answer is
to check Simtel20, WUArchive, or look for the program's name in the
Archie FTP database index.

Here is information about Archie, taken from the alt.bbs.internet
services list:

[...]
 -Archie                telnet archie.mcgill.ca or 132.206.2.3 (Can./USA)

Subject: help with Alinco DJ-160 on packet
To: [e-mail]

I want to connect my PK-232 to my Alinco DJ-160 (2m-only handheld) for
use on packet.  The PK-232 manual gives connection instructions for
many radios (incl. the new Radio Shack handheld!) but not the DJ-160.
The DJ-160's manual gives no clues as to the pin-outs of the spkr and
mic jacks; it recommends using an Alinco spkr-mic "for best results."
I don't have a service manual.  I think I've figured out how to do it,
but I'd rather not fry either of my toys, so I seek advice.

The mic jack is a 3-pin stereo.  Testing with a DVM on my (Alinco--I'm
a big fan of "best results" (:-)) spkr-mic, I've found which of the
conductors is ground, PTT and mic.  When PTT on the spkr-mic is
pressed, resistance gnd-PTT goes to about 1K (but not zero).  Perhaps
this is the resistance of the little "xmit" LED in the spkr-mic?
Curiously, when I plug a three-conductor plug into the jack on the
radio, I see 5 VDC across gnd-PTT *and* gnd-mic.  Shorting gnd-PTT
through a 1K resistor makes the unit xmit; shorting gnd-mic does not.
I think this means that I need a 1K resistor in the PTT line between
TNC and radio, and a 0.1uF cap in the mic line to block the DC.  Is
this right?

If you have direct experience or advice, please e-mail to me.  I'll
summarize to anyone who's interested.  Thanks in advance!

This is interesting discussion, but are the rules any different in Canada?
Note that is where the original poster is from. This brings up an awfully
interesting point - we know of the potential difficulties with internet - ham
gateways here in the US. Could they be circumvented by using a gateway in
another country??? (Did _I_ ask that ;-)  Of course, then we might have to
worry about third party agreements and such.

Greatings, I am interested in APlink.

I will bestarting from scratch.

Is there any paticular fearures in a HF rig that I will want when buying for
this purpose?

I can gess that having computer control capability and non relay PIN diode
T/R switching is a plus, But what about others features?

Also, what kind of packet setup would be best to go with APlink?  Just
any gereral packet setup or somthing more specific?

I am very tech. knowledgeable so give me both barrels(of information).

thanks and God Bless in Jesus Name.

Subject: Establishing a group: rec.radio.amateur.packetBBS?
To: [e-mail]

Every so often, someone asks about a packet <> internet gateway.  (probably
should be a FAQ on this).  Anyway, would it be useful to create a newsgroup
that would take all the articles from the packet BBS network, and post them
on the Internet Netnews system?  I would see it as a moderated group, the
moderator would have a radio and TNC grab the packet BBS articles and
post them on this newsgroup.  People wishing to post to this group (and
on the packet BBS network) would send it to the moderator.  The moderator
would check it for FCC rule compliance, and allow the good articles to
get onto the packet BBS network (with his call attached to it unless he
knows your call and he knows that it is legit).  He probably wouldn't
inspect the stuff from packet.  But he would form the gateway for packet
to internet, thus avoiding someone else duplicating postings.
No, I don't have the time or equipment to do this myself, so I can't
volunteer.  (I have posted an occasional packet BBS article, but I don't
have enough resources to attempt the above.)
Why do this?  Well, it would give hams with access to the internet, but
who don't have packet stations, access to the stuff on packet BBSs.
Also, unlicensed people could also get to read these articles.

    obcenities are questionable and are set by local community
    standards. Most groups could pass with little to no problems.

    Wrong here... crypted messages are illegal if the reason for
    encrypted message is to hide the message from other.  Batched
    newsgroups are compressed and not crypted. The reason for the
    compression is to intrease the throughput not hid the contents.

Recent court cases, most notably the infamous "Sh*t Happens" case
in Georgia (USA), may have bearing on amateur radio usenet gateways.
The courts have said something to the effect of (no, I'm not a lawyer
and don't understand all of the Constitutional Law implications)
the state cannot pass laws restricting the use of printed words,
even though the printed words are publically and intentionally
visible.  In the "Sh*t Happens" case a law was adopted that made
printed obscenities illegal.  The courts ruled the law unconstitutional.
Any ideas on how this impacts packet radio?

How does one observing a transmission know whether the binary data is in
fact just plain binary data or is "encrypted"? The only way I know is to
examine the table of contents (as in the case of pkzip) to see if any files
internal to the zipfile are, in fact, encrypted. This is next to impossible
via FTP.

Personally, I would love to establish an Internet gateway via KA9Q so
local hams could access the Internet for FTP, etc. However, I'm unsure that
under current FCC regulations it is possible to do so without getting a
little 'Notice of Violation' in the mail.

A "batch" feed is just a file transfer using a well known, published
algorythim to *facilitate communications*, perfectly legal. KA9Q's TCP/IP
implementation for amateur radio does FTP just fine thank you, and it's
perfectly legal. You still can't transmit obscenities, even compressed
(maybe). This walks into the area of defining obscenity. Transmitting a
compressed obscenity is like transmitting Midi sequences. Is it music,
and thus forbidden, or is it control codes and permitted? In other words,
is an obscene word transmitted as a compressed file obscene? The Supremes
say that they can't define obscenity, but they know it when they hear it.
Will they know it by listening to a compressed transmission?

AEA has an upgrade kit to convert a Model PK-232 to a PK-232MBX.  It includes
a firmware upgrade, a memory upgrade, and a new battery.  It was pretty
easy to install.  I got mine a few years ago, and I think it cost

About five years ago I spent a couple of days running around looking
for electronic surplus places.  I had made up a list but I don't know
where it is right now.  Some places I remember are:

Artesia Metals -- they're on Artesia Blvd. east of Hawthorne.  They
have a warehouse full of parts; I don't remember any test equipment,
though.

Orvac Electronics -- they're on Orangethorpe Ave. out near Anaheim.

R & D Electronics -- also on Orangethorpe Ave. in Fullerton.

Here's a suggestion:  if you can, pick up a copy of Nuts and Volts
magazine.  Look for any advertisement with a 213 or 818 area code or
an L.A. address.  That will give you a good starting point.  When you
get there, check the Yellow Pages in each area you visit.  Look under
the classifications "Electronic Parts -- Retail", "Electronic Parts --
Whol & Mfrs", "Scrap Metal" and "Surplus and Salvage Merchandise".
I built up a fairly complete list for the SF Bay area that way.

I'd be interested to get a copy of whatever list you come up with since
I may be out there again someday.

    Good luck,
    ---Bob.

Internet Gateways

It seems that almost everyone who is talking about an interrnet gateway
aren't familiar with EXACTLY these internet gateways are used for. We
set up gateways all the time and they work fine and legal.
     The gateways generally aren't used for people to access the
internet for file transfers and telnets, but they are used to connec t
other amateur systems together.  For instance, we would have a gateway
in Detroit, Michingan and one in Canberra, Australia. Then an amateur
in Australia on 2m can basically digipeat through the gateways an~d
appear on 2m in Detroit. That person canot connect (excuse the mistakes)
to an internet system nor can anyone on the internet connect (or at
least leaave) our gateways or have amateur access. We can also
FTP or telnet THROUGH the gateways connected to each other. Y
     If the gateway allows it, you can telnet from it to an internet
system, but if you are on the amateur side and are trying to telnet or
FTP to and  internet system, it shouldn't come back to
you since the internet doesn't handle the 44 addresseds used in
amateur radio. Only the gateways know to send the 44.xx x addresses
to the corresponding gateway that can handle it.
     We are in effect 'digipeating throught  the internet' and
n       ot connecting or allowing internet connections to happen.
It is also suggested to shut off SMTP or at least have them not leave
the gateway to prevent non-amateurs from possibly sending messages to
the amateur community.

     On the talk of compressin. on, people use pkzip, arc, lz,
sit, ertccc... all the time for FTP's.  It is a standard mode
of compression and can be used. In fact we run WNOS which does LZW
compression on SMTP's. The intent is NOT to hide our messages or
to encrypt them, but it is to use up less bandwidth and make more
eficient use of our spectrum.  Isn't this what amateur radio is
also about?  Many people are ticked off that compression is going on,
but it's better use of spectrum. Some of the BBS softwares also
do compression and more will be going to it. This will make the day
of watching the forwarding stop, (monitoring it that is), but there
will be better throughput and your messages will arrive sooner.
     We are trying to make this system better and not trying to hide data.
If a standard mode is used, then it's legal.

     As for things like Usenet mail, I'd personally not handle it or
make it very limited baecause that would have to be screened.

Subject: 2 meter rig conversion/ Binary data
To: [e-mail]

I have been reading several of the topics for the past week or so, but I
have had no time to post comments to them this week. So, now that I have
the chance, I think I will take it.

     Several folks have commented on problems adapting older crystal
controlled 2 meter rigs designed to operate in the 146-148 range to packet
operation. When I was looking for a rig to use on packet, an old ICOM rig
designed to operate in this range caught my eye. While looking through the
manual, I noticed it listed specifications for the European model. Recall
that in ITU region 1, the 2 meter allocation is only from 144-146, so in
order to market their rigs in Europe, manufacturers had to produce a
different version. Apparently the only real difference in this model was a
particular crystal. I suggest that anyone who is thinking about modifying
one of these rigs for packet check to see if there is a European version.
If there is, modification should only involve replacing a crystal and
realigning the rig.

     I also noticed the discussion concerning the logistical problems
in setting up Internet<>AMPRnet gateways. One comment was that FTP
transfers, newsfeeds, and the like encoded and so not permissible on the
Amateur bands. However, the FCC rule on the matter only prohibits "codes
and cyphers" intended to OBSCURE the meaning of a communication. Codes
intended to facilitate transmissions without obscuring the meaning
of transmitted information are permissible. When files are zipped, ARCed,
squeezed, etc., the intention is to reduce file size, not to encrypt
information. In fact, transmitting files in a compressed format would
actually keep traffic down on the channel. Binary data is thus not taboo
material per se.

     The real problems for setting up a gateway are making sure
no business, encrypted, or indecent material gets forwarded onto the
amateur bands. I could just see the FCC having a fit over a newsfeed
containing GIF's in the newsgroup alt.binaries.pictures.erotica being
forwarded into the AMPRnet! But to date, I have not seen anything posted to
this digest that might be considered taboo on the AMPR or AX.25 network.
However, the fact remains that unless we get some major rule changes from
the FCC regarding business communication and a realization by J.J. Freeman
that BBS operators should not be held strictly liable for illegal material
transmitted by their automated stations, any gateway is going to have to
employ some kind of human element to ensure improper material stays off the
Amateur networks. I do not believe that the AMPRnet will ever become a
fully integrated part of the Internet simply because of the nature of the
Amateur Service, but certainly the FCC can slack up a bit to allow for the
use of new networking technologies.

That's kind of like saying that if I don't know French and two amatuers are

Hi again.

First of all, let me apologize if my first posting appeared more than once.
I'm quite new to newsgroups, and, to tell the truth, I was under the
impression that I was sending to individual (humans) and hence quite possibly
cross-posted...a no-no I'm no doubt going to be "flamed" for.

I received quite a few responses to my queries, most of them negative, some
of them quite contradictory to others.  I'm going to summarize what I've
learned here for the benefit of others.

1) There are many FCC (and other) regulations which limit the use of packet
radio (and HAM in general).

  - I was told I couldn't use radio for "commercial" business, in fact almost
    everyone who responded thought I wanted to.  This was never my intention
    in the first place (I'm just an individual computer-geek, not an
    organization of them!).

  - Every message (esp. from Internet to packet) must be "hand-filtered" ie
    censored.  Not sure if I like this idea, but it was explained to me that
    one obscene word could jeopardize the licenses of every rig the message
    passed through.  Kind of a *retarded* regulation, but...!

  - You would require a "god-class" licence to read non-amateur sourced
    material over the air.

2) Packet Radio is notoriously slow (for most technologies).

  - TNC's (Terminal Node Controller) only go about 1200 baud (300 for long
    distances).

  - Apparently you can get faster connections, but you've basically got to
    be "line-of-sight", and there aren't alot of amateurs who have upgraded
    to faster modems.

3) Somebody from Hawaii suggested I ask everyone about the "Proxim" modems
and use the unlicensed/experimental bands.  Apparently the throughput is
faster as well?

4) I'd appreciate hearing about hooking packet radio into the satellites...
this sounds particularly exciting!

Finally, I would just like to point out that all I wanted to accomplish is
to get a mailbox on the Internet!  Currently I have to call all the way to
Ottawa to do this, and I wanted to perhaps use radio for a "anytime" method
of access; providing me with mail, news, irc, and ftp.

However, thanks to the generous amount of mail, I understand that radio is
alot more complicated than I anticipated!  The rules and regulations are
quite intimidating to the uninitiated; and are enough (at least in my case)
to scrap any plans on continuing.  You scared me off...thanks, guys!  :-)

But, as one user quoted:

  "...it isn't the computer part that is fun, it's the radio part...Maybe
  we can turn you into a radio-geek!!!"

I *do* like the idea of talking to somebody half the world away.  Oh well,
maybe I'll bug my friend to start hammin' again so I can see what I'm
possibly missing.

Thanks,

Steve Frampton

Short description:

  This device driver for the SunOS kernel allows the kernel network
  layer to send IP packet inside AX25 (using a TNC on a serial port),
  exactly like KA9Q NOS does.
  The AX25 device appears exactly (ok, minus possible bugs :-) like
  any other network device does to the kernel, so you can use any old
  regular SunOS TCP/IP programs (ftp, telnet, etc). (Tested on Sun3/60
  and Sun4/260, SunOS4.1.1.)

Availability:

   Our SunOS AX.25 IP device driver is now available for anonymous ftp
   at ucsd.edu in /hamradio/packet/ka9q/incoming/sunos_ax25ip.shar.

AX25(8)               MAINTENANCE COMMANDS                AX25(8)



NAME
     ax25 - AX25/IP ifconfig Utility

SYNOPSIS
     ax25 [ -v ] <network address> <ham call sign> <tty_name>

DESCRIPTION
     Amateur packet radio enthusiasts nowadays  send  IP  packets
     over  radio  links.  Hanging off a serial port on their com-
     puter, TNC modems are used to provide CSMA-like behaviour so
     that the single radio channel can be shared between multiple
     stations (somewhat like how ethernet works).   Packet  radio
     is  a  broadcast  medium,  hence  the TNC is responsible for
     sharing the bandwidth with other TNC's.  The computer  talk-
     ing  to  the  TNC  must use a protocol called KISS (a simple
     derivative of SLIP encoding) to send/receive packets to/from
     the TNC.

     AX25 packets vary in length.  The packet header at the start
     of the packet has four parts:

     1.   A (guaranteed to be) unique source address.

     2.   A destination addresses.

     3.   An AX25 packet type field.  In our case  it  is  always
      set to UI, to indicate that this is an AX25 datagram.

     4.   A small number, choosing between various  higher  level
      protocols, called the protocol ID.

     The addresses found in the header are a simple 7-byte encod-
     ing  of  the  HAM  radio call sign and substation ID.  These
     addresses are used just  like  ethernet  hardware  addresses
     are,  to provide a unique name for each station.  The proto-
     col ID can choose between many protocols but  users  of  IP-
     over-AX25 under Unix are really only concerned with two AX25
     sub-protocols: ARP and IP.

     AX25 packets (received via KISS encoding from the TNC) which
     are  found  to  contain  ARP or IP datagrams are decoded and
     handed off to the kernel networking code.   Similarily,  the
     network  code  gives  outbound  datagrams to the AX25 device
     driver, where the reverse process occurs: they are  encapsu-
     lated  in AX25 packets and, after KISS encoding, sent off to
     the TNC for transmission.

     Both incoming and outgoing  ARP  datagrams  require  special
     handling.   The  Unix  kernel's  internal ARP cache contains
     translations between 4-byte IP addresses and 6-byte ethernet
     addresses.   It's convenient to not rewrite the kernel's ARP
     implementation, so an encoding scheme  was  developed  which

AX25(8)               MAINTENANCE COMMANDS                AX25(8)



     converts  7-byte  AX25  addresses  to/from  6-byte  ethernet
     addresses.  This is too twisted to describe here,  so  refer
     to the device driver source.

OPTIONS
     You must be root to run this.  It's a good idea to start  it
     from /etc/rc.local in the background.

     -v   Print out more information while setting up the link.

     <network address>
      This provides the IP  address  for  the  network  port.
      This  name  gets  passed to ifconfig(8), so it can be a
      name out of the hosts(5) database.

     <ham call sign>
      This is your HAM call sign, with your substation ID.

     <tty_name>
      Communicate over the named device at 9600 baud.

     TNC's that toggle DTR for each  packet  can  cause  problems
     because streams M_HANGUP and M_UNHANGUP messages are treated
     incorrectly. If you see console messages about M_HANGUP  and
     M_UNHANGUP, cutting the DTR line will solve the problem.

Haven't seen such a review, however, I have reviewed all of these units for the RTTY Digital Journal (MFJ still in review).  The MFJ would be the easiest to upgrade to 9600 on VHF.  Just takes a daughterboard plug in.  AEA PK232 doesn't really support 9600 yet, but probably will soon.  KAM by Kantronics uses there Data Engine to get 9600.  HF reception on all of these units on Packet is similar.  I like PK232 on Packet. KAM on CW and RTTY.  MFJ on Vhf Packet.  All pretty darn nice units.  Right now I reall




y like the KAM with the HostMaster II software which allows me to monitor PacketCluster and mess with the other digital modes at the same time.

How about alt.bbs.packet?  It would fit nicely under the alt.bbs.*
heirarchy, and since it was an alt group, you wouldn't need the formal
call for votes such as in a rec.* newsgroup heirarchy.

I don't really have a problem with it, but it depends on someone with
lots of time to come in and do it.  Any volunteers?  (I already manage
the Elmers list, and would be happy to add to the list such a volunteer)

Check out news.lists, news.groups, news.announce.newusers, and alt.config
for more information.

Actually, there exists a general FAQ for the newsgroup with a pointer
to a gateway discussion mailing list.  There is also a list of all
current gateways.

Both should be available via anonymous FTP from ftp.cs.buffalo.edu or via
mail server from [e-mail].

The rules say that you can use "any code" to facilitate communications
above 420 Mhz. If you aren't using a standard code, you must keep a
copy of the code at your station so the FCC can request it to decode
something they monitored if they want to. Just because Joe Average
Frequency Cop can't turn "monitor on" in his TNC and print plaintext
on his ASR33 is no reason to stop you from using a particular coding
method.

That's not exactly what the court said. Basically, they said that that
particular message was social commentary and thus had "redemming social
value". That's the catchall phrase they use when weaseling approval
of dirty language, pictures, and exibitions. They also said that the
Georgia statute was "impermissably vague", their weasel words meaning
that they didn't know how to interpret it.

As you may know, the FCC quit enforcing their 7 dirty word list some
time ago because Commission lawyers said it could infringe speech
containing "redeeming social value" or speech that met "community
standards". Very recently the Commission has tried to crack down
on "Shock Radio" with no success. Tipper Gore's pressure group was
trying to get it banned, but the Commission's lawyers couldn't find
a sufficiently weasel worded regulation that would stop it and still
pass muster with the courts. They tried a couple of approaches, but
so far they have lost in court.

The FCC has tended to take a market approach to regulation in recent
years. They have taken an extremely relaxed approach to technical
standards. Their contention has been that stations that don't put
out high quality signals won't get good ratings so the problem is
self correcting. In matters of content they tend to follow a similar
line. If it gets good ratings, it must be meeting community standards.

I'm not a lawyer either, but my company keeps some very expensive
ones on staff to track First Amendment cases. They publish internal
memos telling our staff what they think we can and cannot do. Their
current opinion seems to be that short of live sex acts we can transmit
anything. And they're not too sure about the live sex acts. :-)

I'd like to run K6STI's   MNJR program on am Amiga 500 computer, which
is not an IBM compatible computer (uses a 68000 cpu).

 Does anyone know if the source code to MNJR by K6STI is available, so
that I could try porting it to the Amiga?  (Yes I realize the program
is copyrighted and I am prepared to pay for the source code).

If the source code is available, could someone please send me the phone

Proxim is a supplier of 902-928 MHz spread spectrum transceivers.
They are available in two different power levels (100 mw and 1 w)
and do not require licenses to operate (under Part 15 of the FCC rules).
They are capable of data rates in the 200kbps range.  Proxim is located
in Mountain View, CA.

With the present rules, I agree with you, but a major proposal appears
to be in the works to relax the business prohibitions for amateur
radio.  Perhaps this is our chance to see if the rules could be
changed to clearly allow automatic gateways with the Internet.

I've seen some mention of Ka9q's telnet using ansi.sys for console output.
This leads me to beleive that it may be possible to redirect it's i/o streams.
Has anybody tried this?  If DOS console reads and writes were redirected to
the serial port via a BBS style program, could Ka9q's telnet be used from
a terminal?

Hello MacUsers,

Harald Koch asked in his message of Dec 91 about Macintosh Ham Software.

Well I'm glad to say that at least here in Europe things seem to be getting
a little better day by day. To begin with, Mac's were prohibitively expensive
here, but with the introduction of the Mac Classic this seems to be changing.

Anyway here is a list of some of the Ham software that I have seen running on a
Mac.

1. NET/MAC, TCP/IP for the Mac.
2. AEA MacRatt, controler for the AEA PKP232, excellent.
3. GrayLineMac, grayline stack.
4. TalkTerm, talking terminal for use with DX clusters.
5. Broadcast, for use with PACSAT'S.
6. KISS_TLM, for use with OSCAR 13.
7. MacShortwave, propagation predictor.
8. IM/Mac, better mailer for use with NET/MAC
9. Morse, morse code tutor.
10. Various Hpyer stacks, including one that I'm just about to finish
which will control TX/RX rigs that have a RS232 interface.

This is just a small sample of the stuff thats available. It's there, you
just have to look hard sometimes. Another place worth looking at is the
ARRL Project Mac. Ofcourse the telephone BBS's can prove useful.

If you need any more information on any of this please feel free to get in
touch.

I recently laid my hands on a Paccom Tiny-2 with their NB-96 internal
modem.  I have no paperwork on this thing (Paccom is sending it) but
I was wondering if anyone had converted one of these over to 19.2K
baud and had pulled TTL levels out of it to drive the Kantronics D4-10.

I'm currently running a Data Engine with 9600 & 19.2K modems on 2 meters
and 440 respectively, (and I really like the Data Engine by the way), but
I'd like to convert and use this Paccom G3RUH design on 19.2/440 Mhz.

Thanks for any and all help.

Anyone interested in these Part 15 data radios should keep "caveat
emptor" in mind. Many units are "spread spectrum" in name only, i.e.,
they spread only because the FCC requires them to and the receivers
exhibit no processing gain. This was clearly against the spirit of the
rules.

The FCC closed this loophole over a year ago but they grandfathered
the existing units for two years, I believe. Newer radios meeting the
spirit of the old rules (and the letter of the new) are starting to
appear, but they are significantly more expensive.

Also, I do not know of any Part 15 spread spectrum data radios that do
automatic power control, which I believe to be essential for any
spectrally-efficient spread spectrum system.

Actually, it's "above 50 MHz", AND it applies only to "domestic
communications" (between points under the FCC's jurisdiction).

The FCC has never groked the concept of protocol layering and
modularity.  That's how they can talk about "ASCII" and "AX.25" as
though they were both "protocols", and why asking them whether sending
binary computer programs is "ascii" or not is probably not a good
idea. Just do it.  It doesn't matter how intricate your coding and/or
compression schemes are, if you are not DELIBERATELY taking steps to
hide the meaning of what you're sending, then as far as I'm concerned
you are not violating the no-cipher rules.

Looking for Packet Groups
Looking for Packet Groups

I'm looking to find other packet groups or organizations that would like
to exchange ideas and information.
     In the state of Michigan (USA), we have a recently formed group called
MIPAC, Inc.   (Michigan Packet Council). This group covers presently
convers the entire state of Michigan.  There is also an unofficial group
called PTIG  (Packet Technical Interest Group) that is in SouthEast
Michigan.
     We're still trying to even get a decent system up around the state
we still don't have connectivity everyone. We have no direct routes
between the East and West sides of the state (about 200-250 miles apart).
Probably the best coordinated systems are the DX Clusters backbone,
GLNET (comprised of TEXNET nodes) on the West side of the state, and
the  Detroit/Windsor TCP/IP switch/server site with it's NETROM/TCP-IP
backbone to Ohio (about 60 miles).
     I know that many many other people have gone through the problem of
trying to set up a state or country wide system and have dealt with
problems. Many also have packet groups that have solved these.
     I just got hold of a paper from the NEDA (North East Digital
Association) that I thought was very well done explaining a lot of terms
and showing maps of the packet system.   Are there any other groups out
there that would like to share information also.  It would be good if
groups talked to each other and learn from each others mistakes and
problems.   The MIPAC is still new, but we are putting together a new
list of stations in the state.  We are also trying to decide what type
of systems should be put in too.
     One of my goals would be the capability of passing various protocols.
Since I run several TCP/IP systems, I would rather see NOS switches go
up, but that's not always practical. I have asked several times on here
for any info on Flexnet, but noone responded back as to how to get hold
of one of these units or who to even contact (guess we won't try that one
then).  I like what the people in Georgia are doing, but that might still
be out of our price range.
     We are still seeing about getting a post office box for MIPAC, but
I can let other groups know when we do get one and what it is. I would
like to get some kind of 'point-of-contact' or address though from other
groups.

The fellow who writes ARA's packet column (I've forgotten his name) keeps
insisting that NET/ROM is illegal in Oz. Is this a result of differing
interpretations of the regs, or has NET/ROM been modified to make it legal, or
what?

Subject: BAYCOM, working, but HELP
To: [e-mail]

I need some help with a problem that I have been fighting for
several days with the BAYCOM packge, if anyone is familar with it.

I can connect to most of the stations in my area, no problem,
direct, digi, BBS's, etc.  However, there is one BBS that I cannot
connect to, which is the one that I want to use as my home BBS.

I was able to connect last week, but I haven't gotten into it since.

I can connect, just fine with:
    :c N0IHY-1
        (K-node), I get the "Welcome" (but I still have to learn
        about it!).

If I try the connect to the BBS:
    :c N0IHY-3
        I see his packets comming across the lower part of the
        screen just fine, but they don't get into my recieve
        buffer.  I see all the retrys, and can't see any errors.
        It is a good strong signal.
            His packets start with:
                [MSYS 1.2  H$]
            (umlauts turned off)
                Data follows for intro to the board.
        The info that I see on the screen looks the same as any
        other station.

I have tried it using digipeaters, no change.  As I mentioned, I can
get into all the other stations without problems (usually instant
connect.)  I'm running an ICOM 245 (also tried my handheld) to
a homebrew J-pole on the roof.

I don't have the "cnot" feature enabled, to prevent a connect.
The voltage setting on the TC4305 (?) is 2.75 volts, I have tried
varying this a bit, without success.

Anyone have any other ideas?

Subject: DAMA implementations ?
To: [e-mail]

Hello!

I've read about an alternative mode of the AX.25 link protocol, called DAMA
(Demand Assigned Multiple Acess). It makes use of polling to control access
to the radio channel. (like ARM-mode HDLC) The throughput should be better than ordinary balanced mode AX.25 with CSMA, because the collision rate is drasticly reduced.

My questions to the net is: What implementations of DAMA is available? And where can one get them? (I've only heard about The Firmware 2.3 D )

Has anyone made experiences with this mode?

Best 73!

Up to now I only knew about The Firmware 2.3d implementation. But I heard as a
rumour that there some guys which try to port this implementation to the
PK232. The PK232 would then probably behave like a TNC2 with The Firmware.

If there is interest I could post (or mail) the binaries of TF2.3d

>Has anyone made experiences with this mode?

Sorry not yet, as I didn't got an digipeater with DAMA facilities in my
neighborhoud. On "normal" digipeaters the TF2.3 behave as was before.

I am starting to do some experimenting with TCP/IP over packet.  I have
a fair amount of experience with IP on the Internet and have some
questions about how it is done over packet. Routing seems to be the
real problem.  Do you have to use static routes for everything?  Is
net 44 subnetted?  Are there future plans to get some sort of routing
protocol running?

Phil,

Yes, at present static routing is pretty much the default (pun). There
has been some experimentation with SPF protocols (RSPF) but it's not
really ready for prime time. NOS also includes RIP, but except for very
limited situations it's not really suitable for radio.

Network 44 is subnetted by geographic area. At present most subnets are
isolated "islands" but an increasing number are interconnected by
encapsulating gateways that use the Internet to provide virtual links
between them.

IP routing in the amateur network is a fertile area...

A routing protocol specifically designed for packet radio, RSPF, has
been experimentally implemented.  Based upon the link state - SPF model
of routing, RSPF is a small (for PC use) protocol which supports
NOS-style node groups (subnets) in both backbone and local configurations.

The existing implmentations are a bit iffy, but the N1BEE variant
on PA0GRI's NOS, available from ChowdaNet in RI (sorry, I don't have the
number handy), is pretty stable.  I'm the protocol's author, and while
the current test code is based on V2.1 of the spec, Mike N1BEE is
about to work on my not-yet-released V2.2 of the protocol.

Other than that, there's TheNet and its clone ("NET/ROM"), which is
sort of an autorouting program for packet radio, and there's ROSE,
which I suspect is more static though based upon X.25.

NET/ROM uses a "distance vector" type of routing algorithm which has
serious problems on unreliable radio links. ROSE uses static routing,
but unlike the author of NOS, ROSE's authors actually tout static
routing as an "advantage" of their system.

The first rule of American marketing: if you can't deny it, emphasize
it.

Subject: Packet TNC Compare (AEA/MFJ/KANTRONICS/etc)
To: [e-mail]

This sounds like a probable FAQ but here goes since I have not yet seen it:

I want to buy a TNC in the next few weeks and wonder if a feature
compare among the main 3 or 4 TNC vendors exists?

I'm tending towards a VHF/UHF TNC with mailbox rather than starting
with a full featured all-mode (150 buck price tag vs near 300
for an all mode being the reason).

In addition to a feature compare, would appreciate comments on what
I might be missing out on with the $150 range vhf/uhf versus going
the full all mode route.

FYI I plan on using 2M mobile and/or ht, perhaps 70cm radio also.
I also have a Kenwood 440 on HF (I wonder what kinds of things are
in the ham bands and non-ham bands that might be interesting to
listen to with an all-mode controller?)

In the computer dept, I have a dumb terminal (e.g. VT100 kind of thing)
and a primitive IBM PC with CGA monitor.

Would appreciate any and all advice... will post a summary of
all replies when the dust settles down in about a week or two
on these main questions of:
   -Feature compare/opinions of VHF/UHF/mailbox TNCs
   -  "         "               ALLMODE TNCs
   -What "out of band SWLing" on HF is out there which would be
    neat if I bought an ALL MODE controller?
   -etc.

Whoa! There is absolutely nothing in the present rules that says you can't
compress, so why do we need an exemption? I'd like to nip this one in the

This whole discussion of whether binary data is encrypted points out
what I think is the key reason the regulations need to be changed.
The whole concept of encrypted vs unencrypted is obsolete, as are many
of the distinctions between business and personal. (I download a
program in source form for my personal use. I really like it, so I
take it to work. Maybe that breaks the rules, maybe not. Who knows?
Who really cares?) I think regulation of content has become completely
impractical, and the FCC needs to get away from it except in the most
basic and critical forms. (No regular use for business, no sale of
communication services, no kiddie-porn over the airwaves.) There should
at least be an exemption for compression for the purpose of bandwidth
reduction using published and publicly available formats.

This really belongs on the policy topic. This is the short form of my
opinion (and only my own), so please don't point out all the holes. I
know they are there, but I don't want to type all night.

Face it:

    The single problem which differentiates HAM radio networks
    from commercial networks is subtle rules which restrict
    freedom of speech. No posibility exists for a internet-packet
    gateway with this restriction.

    Unfortunatly this restriction is the only thing keeping the
    HAM bands from becoming a usefull tool for me.

    I see a compromise. Net news is a public access net with
    fewer restrictions. Specifically advertising is restricted.
    I would love to receive my email on packet from work. This
    is an acceptable Internet option not a HAM option.

    Perhaps it is the recent announcement of a email service
    using packet radio technology in an News article I just read.
    I am sure it uses the stolen portion of the 220 MHZ band.

    The article also said it is a first to offer email using radio
    Ha Ha dream on. See comp.dcom.telecom for announcement.

    I do not want to order a pizza using my 2MTR HT but to me this is
    not a good point of view for paket radio. I will admit that much
    of the bands are being under utilized. What is the point of
    AX.25 if there is no one to colllide with.

    CB has had a bad name and understandably so but I use it as it was
    intended. When I have to follow my girl friend to the auto service
    center we can talk about her lanscaping business and about my work
    without a problem.

    Talk about useless the pile-ups on 10 meters.

    The answer here is the redefinition of HAM to be personal
    communications not the communication to make contact rule.

I don't mean to be too pointed Dave, but your 4800bps modem and Nos node

anything ... too much bickering.. too much in-fighting .. not enough

There is a wonderful lan is VK2, there are about 6-7 nodes running on it,
it will increase as facilities available increase, and others get themselves

There's an even bigger drop in interest when so-called Amateurs find
out they have to actually scrounge parts for a project.  It's the Dick
Smith paint-by-numbers kit mentality...  One bozo was actually
threatening to take the local supplier of the G3RUH 9600 bps modem kit
to Consumer Affairs, because it wasn't what he expected.  That's funny
- it was advertised as being a PCB, an EPROM and a parts-list (plus
circuit) - that's precisely what was supplied to him!  Said bozo also
accused me of not being a "real" Amateur (whatever that means) because
I didn't have my 10 wpm CW (whatever relevance that may have).  I guess
he started "ad hominem" attacks on me because he couldn't refute my
arguments.

That would be John Day VK3ZJC - he's also a director of a certain Amateur
shop in Melbourne, so may have a bias towards certain TNC's...  Anyway,
NET/ROM is illegal at level 2 (where most packet activity occurs) since
the packets do not carry complete identification (they carry the ID of the
local NET/ROM node instead).  It is however allowable at level 3 (the network
layer) and is commonly employed there.  Rumours abound that the DoTC are
turning a blind eye to its use at level 2, with a view to the eventual
de-regulation of Amateur operations, but AAPRA hotly deny this (I guess
they have their own hobby-horse to push i.e. ROSE...).

Steve,
under U.S. regulations (don't know about Canada), it is "questionable"
if you use ham radio to circumvent toll charges, even if the traffic
is non-commercial.

As for the speed of packet, your information is somewhat correct (1200
baud), but overly optimistic.  #1) it's a half duplex circuit with
turnaround delays; 2) since others may be sharing the same channel,
there are collision, retransmissions, etc.  On a GOOD 5-10 mile
connection, good throughput is closer to 100 baud or less.  For
longer vhf distances, multiple hops are required and it is abysmally
slow.  ONLY A COMPUTER HAS THE PATIENCE TO PUT UP WITH PACKET SPEED
OVER ANY DISTANCE!  (Yes, there are a few areas which have higher
speed trunks.)  For really long distance (50-500 miles), actual
throughput is probably closer to 10 baud or less.  Yes, I can send
morse code faster than hf packet!  (OTOH, the computer doesn't mind,
it has much patience!)

Is there a source on the Internet for the G1NNA PBBS software?  I believe
the author himself shows up here from time to time, so it's curious that
his handiwork is so hard to find...

I have the following system for sale:

    Tandy Model 102, 32k ram
    Ultimate II rom (spread sheet, word processor, etc...)
    Disk drive (3.5 inch, battery powered)
    Bar Code reader (with software)
    Cassette interface

     All of this stuff, including the carrying case that I have the machine
in, for a measly $270.  I have recently purchased a Toshiba T1000SE
and find that this guy is sitting in my closet unused.  It makes a great
portable packet station since it has the built in com port, also has a
built in 300 baud modem.  And with the disk drive there is a lot more
storage available.
     This setup would generally cost you in the neighbor hood of $600-700
to purchase.  All your for only $270...

At the moment DoTC IS turning a blind eye towards NET/ROM, IP
routing, BBSs and numerous other "transgressions".  The Wireless
Institute of Australia is hard at work on a "deregulation"
proposal to be put to DoTC and when it lands there's going to be
a monumental shakeup. :-)  DoTC is fully aware of what is
happening though.

VK1 isn't that great and VK3s is rather slow.  I can give an
"expose" if you like. :-)

I beg to differ.  It does depend a bit on one's definition of what a gateway
does, but I feel sure that I can(have) implement a 'gateway' that is both
very useful to me as a ham and still within the rules.  Email me if you want
to discuss details or exchange opinions.

Hah!  There is a lot of commercial activity there, by any definition.
Some of it is what makes the news groups worthwhile. {Sure wish ICOM & Kenwood

Ouch!  Well, I have started buying the components for the 4800 modem (and
also started on the SCC port on the Microbee as well).  Someone has also
thrown another 286 motherboard at me as well, with flaky tracks to be
repaired (you don't expect me to BUY pc-clown bits, do you?).  But yes,
too much talking and not enough doing...

Perhaps it could be better publicised, if you want more people to join you.

GfxBase uses the SanaI protocol to connect to local domain and DECnet
style connections. If AmigaNOS were made SANA compliant it would be
a small job to get GfxBase's X11 to work with it.
