[arm-allstar] Radio-less node

[Don Ritchie]

Thanks all, that is the way I have it setup.

Mic Hi, to pin 6 (Disc)

mic PTT to pin 3 (Cos)

incoming audio is pin1 to audio hi to powered speaker

AND, the "other side" of everything to pin 8 (Gnd)

My problem, I don't think I understand what to do next.

There all sorts of "plans" but no operation instructions !!

As near as I can tell, I have the USB invert set correctly.
