My DMR radio hears just fine, but the best explanation for the high bit error rate on transmit Is some kind of frequency drift.

I'm running OpenGD77 on an RD-5R, with an #OpenSpot4 as the hotspot.

I can see two, maybe three ways forward.

1. On the RD-5R, "Freq Adjust" from the calibration screen.
2. On the OpenSpot4, "Autocal" as described by https://manuals.sharkrf.com/openspot4/en/autocal-connector.html
3. Why not both?

Of the two Autocal looks easiest, and it will get me the best diagnosis out of the box.
