My OS 4 Pro stopped working

SteveEJ

Prior to the latest firmware update my OS4 Pro worked fine with my Anytone 878UVii. Since then I get a Color Code error and to use AutoCal. When I try the AutoCal it keeps looping thru phase 1/3. Occasionally it goes to Phase 2 but goes right back to phase 1.

Any ideas? I really need to get them working with each other again.

Thanks!

You could try adjusting the OS4P Rx frequency by 100Hz steps and as far as +/-2.5kHz this is a manual method of doing part of what the autocal does.

The colour code problem is because the CC part of the DMR header has essentially no error correction and it only takes one bit to be in error and it won't match.

Maybe this applies:
