    Well I can tell you the DC should not be present from a power supply unless the switch is turned to the DC position so if that is true then somebody wired it that way. This may or may not be a problem depending on what they did it could make voltage present on the DC socket while in AC mode?

    Thank you OldTech03,
    this occurs only when switched to D.C. on the rear panel, but the radio is on when the main power switch is off, the frequency counter is off (displays clock) but the radio is on and running.

    I think this ishappening becauset main power switch is switching ground (?), and the external supply is proving positive and ground when it itself is on? (I've yet to get the schematic open this morning)

    The only advice I could add is on the IR camera. I'm fairly sure they have IR apps. Whether or not they work I wouldn't know. But it's worth a shot. Good luck bringing back an excellent transceiver to its former glory. So far it seems like your devoted. I would guess that this mm has a good chance considering its being done by someone who's devoted to getting it completed. 73

    I forgot to update this thread, oops!

    Thank you for the kind words, Sonar. :)

    The radio is all done and works 100%, just waiting on decals & LED's for that custom look.
    (the bezel on this radio is beat up) :cool:
