G7TSX-9 APRS

Finished the APRS mobile project, I just popped it into the boot and been out for a quick drive. Nothing on aprs.fi…! I’ll put this down to the poor APRS coverage on the Wirral at present, though I note both of the reasonably ‘local’ iGates are both showing as being ‘on air’.

I’ve used the data output from the Icom 2820 to provide NMEA sentences to avoid the need for a second GPS RX in the car. This feeds the APRS modem via a MAX202 RS232 level driver to fool the 2820 into sending data (It needs to see a true -8V RS232 level or it outputs nothing) to it. The radio is my oldish FT-51 with the broken battery pack. Try finding a replacement part these days so I hard wired some power cables and use it for projects such as this. Whole setup is very neatly installed in a small enclosure and hidden away in the boot.

Will ensure I have it enabled for the trip to the office tomorrow and see how I get on.
