if the antenna warning indicator is lighting during transmission then the antenna is either located and.or installed improperly or a defect exists in the antenna mount or the feedline itself, including connectors.

SOURCE: Radio lights up, but no TX/RX.
Hi and welcome to FixYa,
Based on your description, a possible drift in the local oscillator. Check the 10.24Mhz crystal filter and its local oscillator for output and consistency.
Good luck and thank you for asking FixYa.

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."
The red light on rx is fine, it's supposed to change from green to red. The red light on your antenna means you have a swr issue, something in your antenna system is not right. You need to go to a reputable CB shop and have them check your swr.
