Sounds good. Definitely a good idea to get the second station working, to make sure you're running the correct audio levels to not distort the modem tones. Those old hardware TNCs are picky about matching amplitudes for the two tones and not invoking audio compression in the transceivers.

Hi

Andrew many tnx for the advice.?

I followed your advice and the TNC 220 appears to be going into KISS mode when I run YAAC instead of me having to manually put it into KISS mode.

I have set it up as an APRS beacon (60 secs intervals just for testing) and the STA and TX lights are coming on as I would expect and the 2M TXR is TXing and I can hear packet tones on a handy.

My problem is there is only one other active APRS stn in my area about 10 miles away but there is a mountain between us so the path is vy difficult.? He is decoding nil but that my well be due to the poor path.

I need to set up a 2nd portatable APRS stn to see if my packets can actually be decoded.
That's my next step getting YAAC running on a RPi with my other TNC a Paccom TNC 320.

Will report the results.
