Hi,

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.

How do i convert my cobra 29 nw mic to a road king 56 mic?


Look closely at the jack for the microphone and you can see the small numbers that are on it. On the Roadking red and shield (bare) go to 1. White 2, Blue 3, black 4 and the yellow in the cable does not connect to anything.

Microphone not working


I think it is safe to say 90% of radio problems are microphone. You get a cheap one when you by just about any radio. I believe you are seeing the meter move but not getting audio from your talkback. No matter remove the mic jack plug from radio. For you particular radio looking at the end of the jack notice the small raised numbers. These female connectors no matter the mic type wired for this radio model has the following wires connected or in your case disconnected. 1-(Ground) 2- (Audio) 3-(Transmit) and 4- (Receive).
A RK56 mic would be my suggestion Astatic 636L the second choice a little cheaper but audio it not a crisp.
Don't waste your money a repairing the mic or buying a diesel or road pro or even a cdl mic like a cdl 56 or that Skythumper they are RoadKing 56 wannabees. Sorry about the rant my point is RK56 is Quality.

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.

Cobra 29 ltd classic: i can hear other cbs but can not transmit out also the light is out on the meter


The most likely cause broken wire in mic a nice Roadking 56 would be a nice addition with better audio than factory mic.
The meter light is unrelated they burn out and can be replaced without replacing meter. Different colors and rainbow lights that chenge if you prefer. I find them annoying.
Good luck
Cobra Highgear mics are sold in Pilot truckstops that is a cheap replacement. There are the versions basic,noise cancelling and power mic. The power mics are for stock unmodified radios and will mostly squeal on a tweak radio from cb shop.
Durablity and quality audio tone for the price goes to the RK 56 mic they are about 70 bucks with tax at pilots.

MIc. feed back


When ever an Export radio is modified and tuned especially the talk back it will feed back bad!! When you have this tune done to the radio the stock microphone is no longer any good to use and no longer an option!! The radio tech. should have explained this to you!! You will now have to use a very good quality Noise cancelling Microphone for the Connex it is recommended to use an Astatic 636L Microphone. They work real well with the Export radios or if you prefer you can get an Turner RK-56 Microphone but they are alot more expensive and my opinion is the the RK-56 is over rated and they do rob your radio of some audio!! The Astatic 636L gets rid of most feedback problem and make your voice soumd crisp and claer!! If that dont do the trick than you have to take the radio back to the tech that did the work and tell them to install a larger resistance on the talback modification they did!!
