Might have found the issue today. I put both radios into service mode.

The 800mhz radio lists CH Version as R12.00.04 but the VHF radio lists CH Version as R00.00.00. I suspect this is all related. Can anyone provide some guidance on what my local shop needs to do to fix that? They didn't have ...

Sounds like maybe it wasn't properly installed. The symptoms are indicative of the CH PCB not being properly seated and the compression contacts not making full contact. Ensure the tabs on the PCB are properly aligned with the grooves in the housing

Now that I have had a chance to take a working ...

I tried searching this forum and could not find anyone discussing this issue. I know someone that has a CDM1550 and recently purchased a remote kit.
