Mmm, interesting idea. But, again, the 1271A manual mentions nothing. Thanks for the thought,

The only thing close is an "Accessory Socket", but it only does stuff like squelch output, PTT switch, fixed AF output, ALC voltage, and some other analog stuff. Nothing related to the frequency setting.

In preparation for the ISS L-band uplink, I maybe have barely enough uplink power to get in, but it will need to be right at mid-point on an overhead pass. That's when Doppler shift is the worst.
