Kent my good man, you are both "right" and a genius.
Yes I have the?MH-59?Vertex Standard all-everything mic.
Unplugging/replugging the mic didn't do anything, so I looked at all the mic buttons, and just started pushing them to see what happened. I'd never really engaged with the mic options before. Things happened, or not.
Finally, at the bottom of the button field, there is one in plastic orange labeled FAST -- and that was the culprit. Cycling it changed the tuning and I was able to get it back to reality.
Now I have lots of reading to do that I hadn't expected. Never a dull moment.
Thanks so much for your expertise and your most helpful response.

See page 119 of the manual for reset options.

I'd also disconnect the microphone, turn rig off, then back on, especially if you are using the?MH-59?A8J microphone.? It may be controlling the frequency display.

Good luck ...

I have a different primary rig, but often dig my 857 out of it's storage box under my desk to play with it, learn it, and plan how to use it better. When I put it away some months ago, everything was Fine. But when I hooked it up yesterday to test with an ATAS, it wasn't as Fine as it was before the last nap.
I soon noticed that the last digit of the frequency display was stuck on "7".
So, when I spin the dial like this: 14 . 300 . 17?all digits move as directed except for the trailing 7. This means I cannot got directly on frequency, ever, and often SSB voices are just a bit more donald duck than they should be. Maddening.
I tried changing Menu 82 SSB step to change the tuning steps, but no real help here.

Suggestions welcomed, please. I will send it to repair if I have to, but would like one shot at fixing it myself. I'm not a competent tech, but can probably work through easy stuff.
