Hi Jim

I started with one of the oldish 1200/300 BPS TNCs maybe 10 years ago.
This was when PC's didnt really have the grunt to do DSP on incoming
sound card signals.

Nowadays I use the sound card DSP systems for any kind of digital mode.
This gives you greatest flexibility to run all kinds of systems and
modes from packet to PSK31. I dont however know if APRS will run on top
of (say) Tom Sailor's soundmodem engine for Windows. I am pretty sure it
does on Linux though.

Obviously a TNC for mobile use will have a smaller footprint in the car.
I assume for APRS one changes/reprograms the EEPROM or has one with the
purpose built code extensions. Or setup a portable computer as well.. (I
mean you need a GPS box too)

Sorry I have not played with APRS as such.

Brand new to ham and, even more so, packet. APRS looks too cool. What
to buy? Which TNC would last from initial fumbling to mobile APRS. Or
is that a stupid expectation? Then just tell me about your packet/APRS
system congfig please?

Tnx and 73,
