Problem with XTS3000 not receiving distress ack from the console

[m_plaxton]

I have a few XTS3000 radios that do not accept the distress acknoledgement from the console and continue to send the distress signal.
Motorola no longer supports these radios and firmware updates are no longer available through MOL.
The radios themselves have been tuned to spec, but the problem persists.
I do not have the proper test equipment to do a BER or Test Pattern check.
I have tried cloning a known working radio with no change.

Has anyone run into this before, know how to resolved the issue, and what is the cause?

Thanks for the assistance.

Can you include more details? What kind of system, what kind of mode (analog/p25,etc), what kind of console, etc?

Issue resolved

The problem appears to be with the Deviation Balance in the Motorola XTS3000.
I performed a pre-test on a radio that had come to the shop for service due to a damaged LCD screen. The radio received the acknowledgement from the dispatch console before I tune it.
I tuned the radio and then tested the Man-Down button and the radio no longer received the acknowledgement from the dispatch console.
I worked backwards through the tuning procedure and tested the Man-Down after each step and it started working again after I reset the Deviation Balance.
