Does the rx/tx green light stay on all the time? Cobra 29LTD

Yes the light will stay on and change when you key the mic

3 light on last two blink

The first light, I assume is on constantly, is power/connection, and the two that blink will be Rx and Tx, Rx = recieving data sream, Tx = sending data stream, even if you think that nothing is being transmitted, "static" is sent/recieved to maintain your connection.

My galaxy 959 cb radio wil not put out any transmit


Based on your post of no transmit, a couple of possibilities:
1. defective microphone or cord or PTT switch (the red TX light does not come on when pressed);
2. TX light comes on but no output, defective finals and/or drivers. These are the transistors screwed to the chassis of the radio very near the antenna terminal;
3. defective regulator IC that provides the TX B+;
5. insufficient amperage from you power supply;
6. too high SWR.

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.
