I turned on my icom 746 and it went right to transmit!! Tried everything I could to "undo it" but no success... I don't have the service manual
but after thinking about it could it be the "pin diode" switching??
I would unplug any microphone or CW Key that may be plugged into it just so you know it's not one of those causing the issue.I would also do a Complete Factory Reset & see if it unlocks the carrier.Can't hurt in any case.I have an ICOM 746 as my backup radio & it's the 4th one I have owned.
