Question about Cobra 148 GTL 120-Channels Base CB Radio
If the radio receives OK and the TX red LED will not lit up when keying the mic, then it is a mic or mic cord or mic connector problem (or pin configuration). Internally to the mic, there is a switch for keying the PTT. This should be check down to the coiled cord to the connector.
If all of the above checks OK, then you would need to check the TX/RX regulator/switching circuitry.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

1- Shield (Ground)
2- Yellow (Audio)
3- Red (Transmit)
4- White (Receive)
This is the stock mic wiring but why bother just order a RoadKing 56 it is already wired for your radio. I suggest Copper.com dont even consider a Skythumper it is cheaper but the quality is not there.
