CB FM mode TX/RX add-on PCB kit Has anyone bought 1 of these kits off ebay before? I bought some of these a while back and I've never got around to install one. They did come with some instructions for different radios but none for a cobra 29LTD or GTL. The problem I am having is trying to find out where +TX and +RX go in the radio on some the instructions the +RX is not used so can the +TX Be put on constant 13.8V and not need the +RX? On some of the instructions the +TX is hooked to 8 volts on transmit and the +RX is hooked to a 8 volt on receiver.

In that radio I would attach the +Rx to pin 3 of the mike socket. This is as close to a switched receive-only voltage as you'll get in this radio. The +Tx comes from the collector of TR21, the center leg.
Haven't seen a FM add-on kit for a CB since the 90s. CBC International sold them at the time. One 'club' had it installed on their members' radios and figured out it was only good for local use, and only when the skip died down. Haven't yet laid eyes on the kits they sell these days.
