[GreenKeys] Connections

[Jeffrey Golas]

Well you need to decide if you want "fsk" or "afsk". AFSK is where the Dovetron makes the tones, FSK is where the radio itself does the tones. Id use AFSK.

To talk to the Saturday net, you'd want 850 shift, which might be option C on the Dovetron. (You can adjust them in the back). It should be 850 shift centered on 2000.

If AFSK, you need an audio input on the radio, as well as some way to key up the radio and keep it keyed to transmit.
