    Default O5 to O3 control head swap?

    I have a mid power XTL5000 with a remote mount O5 control head. I would like to swap it for a remote mount O3 handheld control head. My question is how difficult is it and what is the Motorola part number for the O3 control head extension cable ?

    Motorola PMLN4958 should be your control cable part number.

    Plug and play, basically. Ignition sense and speaker can be sourced from the front DB25 or the rear 26 pin accessory. Just make sure the side and top button functions are defined in CPS.

    So here are the part numbers that I have for the O3 swap so far, PMUN1034F (O3 HHCH), PMLN4959 (mic extension cable), and HLN6863B (rear ignition/speaker cable)

    As others have said, it's plug and play. Plug the O3 head in. You only need the extension cable if the radio isn't right next to where the head is going to be. The rear power cable should already be there, it's not a special cable.

    Note: You will not be able to program the radio using the USB programming cable, you'll need the serial version.
    Schrodinger's Radio: It is simultaneously too loud and too quiet, but you will never know which until someone transmits.

    This is only true about the GCAI to USB cable. The HKN6163 accessory to USB cable works fine on an O3, I just did one today.
