Might have blown the final amp in the transmitter due to high SWR. Unless you have test equipment and soldering abililty, this is best taken in for service.

Yes you can turn up VR pot inside to recieve max level but will cause noise to be max too. I don't rightfully remember which one does it but I'll refer you to Defcom cb radio mods for a spec sheet
or Snakedoctors cb radio mods google site. Go to these radio mods sites on Google search and type in radio model. It will tell you what Vr inside to turn up RX of RF gain. Turn up modulation and written instruction if you are handy with solder gun how to change a resistor or cap to make it more sensitive recieve. How to replace final stage and resistors to 1/2 watt size for 6 more watts output and spread coils 1/8 inch apart like a comb for 100% microphone loudness or swing output. say 3 watts to 40 watts output. More windshield wiper swing in meter makes loud voice and extends range with Power final boost. Most people prefer to keep a mobile at around 11 watts swing to 45 watts.(but on generic radio meter will show 2 to 5 watts-its not accurate just a cheap indicator you are forward swing). Even though factory says 4 watts FCC hogwash. They come tuned from Cobra with 11 watts to 14-22 watts.Cobra really peaks them babies so competition doesn't beat them out like new louder radios made by Galaxy 55. Even though law says blah blah (corporations bend it)sales pitch Galaxy very heated with Cobra on the game(rich can do what they want)Galaxy is 20 watts factory with big promise to 40 watts dual finals. So Cobra updated and said "screw it we will break the law too" Now Cobra is loud as ever and offering their own super mod versions and dual final radios with 45 to 65 watts output with ranges on SSB & USB of 1500 miles on a strong good outdoor antenna.

You must set the SWR on your Antenna. There is a little more than just pluggin it in. What type of antenna do you have?

I see two possible problems. First, with a magnetic antenna it is difficult to get the proper ground for the antenna. Make sure the magnetic base is clean as well as where you place it. Second, try running your power lead DIRECTLY to the battery and not using the cigarette lighter. Hope it helps.

Check your microphone and the SWR on the antenna.
SWR checks or bench checks should be free at a RadioShop or CBshops, and normally they will only charge for parts needed.

if a mod has been done to the cobra 29 (all 29,s)the light will come on just find vr6 audio the radio as it comes on adjust vr6 untill it goes away,,,,always trust your watt meter(s.w.r scale)over the flashing light its really easy to do it beats paying a shop $10-$15

turn volume and mic gain half way up, plug in an external speaker into the PA jack, flip PA switch and key up, if it doesnt squeal your audio final is blown or it could be so simple as mic wired wrong or broken wire. try another mic.

if you replace it without fixing the problem , well , you sort of still have the problem.

What is the make and model of the antenna? Most have a set screw on the whip above the spring. You loosen that and move the whip up and down
