Thanks, I'll look into the deviation and mic gain.
Tests last night of resetting the processor in the 857D resulted in no change. After about 5 resets and manual configuration on VHF with TEN and without, the 857D could not break the squelch of the HT, even if the HT is in a different part of the house. So unless there is something else, this 857D is not working correctly. Maybe I will remove the jumpers installed for the MARS/CAP mod and reset the radio again.
Again, thanks to everyone for your help.
