Raduino. It was intended to be more extensive, but I had to roll some of it back. Mostly just sharing of enums/types currently. Currently in "factory calibration" mode. Comms (CAT) in normal mode needs to be re-checked. Added two tone test mode, with two new modes available via Raduino menu: TTL and TTU. Using test mode, I'm thinking that the proper TX output calibration, assuming a full-scale 700/1900 test tone, is either: 0.061 (which I believe gives a 25 mV RMS output), or ~0.100 (which is just before the audio starts to distort, in terms of visible harmonics in the spectrum at the 45 MHz IF.
