I can't believe I didnt think of this before! But since Manchester AX.25
for the UPLINK to AO16/LO19 using any FM 2m radio is a SQUARE WAVE, you
dont even need a sound card to generate it! Thus, a Resistor and
capacitor connected to the DTR line in your serial port to your Microphone
jack will let you uplink to AO16/LO19 easily.
*** IF *** someone will write the code...
It doesnt even need to be a full AX.25 implementation. Since all you have
to generate are UI packets! Very simple...
Anyone want to take a crack at this? I could glue it into APRS along with
some satelite tracking and we would have a Mobile Satellite
communicator... FOR ANY 2m FM equiped mobile.
