Only has AM but could be a number of things.First,turn radio on,make sure its on CB not PA,turn squelch all the way to the left and RF gain all the way to the right. You should at least hear something by now. If not look on the front of radio and see if any lights are lit.If the tx light and the awi light are lit its because you have a bad match on your radio.Make sure your antenna is grounded so your signal can be picked up. take a piece of wire and touch the antenna bracket and a ground at the same time.You should hear something. this is as far as you can go without more knowledge of the radio.

SOURCE: Cobra 29GTL Won't Transmit

if the red ant light comes on this means that you have antenna trouble either in the antenna itself or the coax but this should not have anything to do with the radio not transmitting. it sounds to me that you have a bad audio chip or a bad power output transistor. in either case you should really take it to a cb shop and let the professionals solve your problem, good luck!!

SOURCE: Red RX/TX and red ANT light on my CB

Well,first hand ,some cobra radio,s have red some have green RX/TX lights, but are you modulating? Some green lights turn red. What is your standing Wave on the antenna,s? You need to check it and the output of the radio. To do this you need a watt or field strenth meter. Can get one at Radio Shack. Your standing Wave is ok as long as it is below a 2. That has to be done on the antenna. ..hope this helps...

Testimonial: "Thx the rx/tx light is supposed to turn red I found out. Still trying to get the antenna prob fixed though."

Good day I have an cobra 148 Gtl tx and rx a working but no out put

It might not seem obvious but on many, if not all, current CB radios have separate wires coming from the microphone for RX and TX. It seems like the mic wire for TRANSMIT may be open. It is a common failure.

Stuck on rx mode

Rx is an abbreviation for receive. (Tx is transmit) There are a variety of reasons a radio will be "stuck" in Rx:
1) Another radio in the group is stuck in transmit and you cannot reply if your radio is receiving the other radios transmission.
2) Your radio is programmed for Rx only.
3) Your radio has a Tx problem such as a bad mic, or something covering the mic opening.
4) Your battery is low or bad. It takes more energy to Tx than to Rx.

Best regards.

148 gtl cobra cb radio and the rx/tx light stay on

This sounds like a problem with the MB3756 Regulator IC. It controls voltage regulation and TX/RX Switching. It is a common failure in these radios. Check voltages with schematic that can be found at
