[OZAPRS] TNC320

[David]

Hi Tony.....do you have the handbooks or circuit diagram etc

if not please yell and i will send you at least a copy of the diagram 
and i even have a A4 print out of the manual if you would like it.....

i have one of those TNC running on my APRS VHF port...it was modified to 
2 vhf ports but if i wanted to could put it back to its original with 1 
HF and 1VHF
bought it many years ago and it sat on the shelf until about a year ago 
when i got into APRS
