Have a cab-1 that makes the beep sound when keys are pressed but will not respond to the command base. Have new batteries in there, cleaned the contacts on the board inside, all wires are soldered to where they should be.
When I press the keys to communicate with a TPC and/or rotate the red knob, no communication to the base or to the tpc. I even cleaned the inside of the crystal port and used a crystal from a working cab-1 and still nothing. It is not my power/tpc set up as it works with another cab-1 or cab-2. Had the antenna out and was next to the base. I have tried it all and narrowed down to a communication issue with the cab-1.
My question is... Is there a tuning knob inside the cab-1 like the one inside a command base? Wondering if that is the issue.
