To: ham-digital@ucsd.edu
I'm interested in using digital speech encoding to link some repeater
systems together with toll-quality audio and using links of about the
same bandwidth as analog voice circuits. Any pointers to suitable
CHEAP vocoders/codecs and suchlike would be appreciated. (So far the
cheapest chipsets cost around $150 or so and I'd really like to do it
for less than that if I can!)

Along this line, has anyone ever pushed a Mitrek or any other
readily available radio to 38.4 k baud? I'm eyeing the new
Paccomm SPRINT-2, and it can do G3RUH modulation all the way
to 57.6k baud. Just what kind a radios can do this?

All,
Anyone point me in a direction for a source of Motorola Mitrek radios? I would like
to convert some for digital use and can't seem to find a source. Any help would be
appreciated.
Also, am looking for used Kantronics Data Engines. Will pay shipping and going rate
for working units with or without modems.
Thanks, and please email to address listing below...

If you can get a copy, I wrote an article in July 1989 CQ magazine
that discusses mobile packet radio and some possible mounting
solutions.
Did you want to actually mount it under the dash, or do you have some
other place chosen? Is it a car, truck, or van?
Post your results if anything interesting happens.
Regards, and 73,

PacComm's Tiny TNC is pretty small. Would that do for you?

You might try the Kantronics KPC-3 or their new KPC-9612. Both are quite small and can
be powered by a standard 9 volt battery. The KPC-3 (the one I have) can also accept
DC power from 7.5 volts to 15 volts, so powering it off of the 13.8 in your car is possible.
Hope that helps,
73, Greg

If you can tolerate it being *much* smaller than most mobiles, try the
Kantronics KPC-3. Takes almost no power at all and is about the size of
a pack of Player Cigarettes.

I am seriously thinking about getting a new Icom IC-281H, the 9600
baud 2m packet ready radio. Does any one have any experience with this
radio, and how well it performs? Thanks..73's!

One more thing, Could someone please tell me where 9600 TCP/IP backbones
are usually located..(the freq. if possible.) Thanks!

I am considering getting into packet with my TH-78A (it's all I can
afford). What has been your experience? How fast can you go? 1200, 2400,
or 9600 (on 440)? Experience any problems? What do you do to toggle
transmit/recieve? I haven't a clue as to what other have done or are doing
so any and all comments would be appreciated. Thanks!
