[OZAPRS] Ron Graham VK4BRG APRS TINY software

[Ron Graham]

I built a number of variants of those devices in that era .. see comments 
below ..

The PIC is probably programmed initially with TT version 1 .. thus (from 
memory) TT II.exe will not work with it .. you need TT I.exe to program 
your callsign etc. Its probably still on Byrons, N6?? web site .. if not, I 
should still have a copy.

>Where to I connect the cable? The DB9 or the 3 pin header on the board?

Either. If a DB9 is fitted, it should interface directly to a serial port. 
If you have a problem, trace out the wiring to the 3 pin socket.
Verify pin 1 to PIC pin 3 (maybe via a 10K resistor) .. PIC data in. Pin 2 
to PIC pin 2 .. PIC data out. Pin 3 ground.
Later versions used a 4 pin socket here .. with pin 4 connected, via a 
jumper, to +5 V for powering a 5V GPS RX.

Any problems, just give a yell.
