Transmitting on the radio seems to break up every once in awhile, even
when I switch mics it still does it.. Every so often, the radio starts
making a popping, crackling sound, I can turn it off and back on and
its gone for about 60 seconds.. Any idea?
Sounds like you may have a leaky or shorted capacitor somewhere in the power circuits, or a defective transistor in the same circuits since it affects both the transmitter and receiver. Common problems with receive and transmit intermittance can also be the antenna or its connections. The fact that it goes away if the radio is turned off, then on again after a short time points to something common in the power supply section. Unless you have test equipment and a working knowledge of electronics it will be difficult for you to troubleshoot on your own.

Hi, Great radio when it works. If you have your settings on CB - not PA - -be sure that your Cobra has that setting selected. If CB -is selected and still nothing - be sure you have a working mic. These wires are fragile and can break internally. One easy way to check is to borrow a cobra mic or even drop by a CB repair shop and ask them to do a mic check with the mic - it is free.
If you have a bad mic replace it and all should be well. If your mic is good and it still doesn't transmit you will need to replace the finals in the unit. It is common that these burn out of you got too close to someone with too powerful a radio. The CB shop will need to look at it further and repairs should not be over about 40.00.
What happens if you "key up" and "let off" and the transmitter "hangs", you remove the microphone plug from the Cobra ? Will it still be transmitting or will it stop ? If it stops, the problem is in the microphone with a "hanging" switch which you can easily clean or replace. Iif it keeps transmitting while the mike is disconnected, there is a problem with the Rx/Tx switching circuit. This needs further investigation by use of a circuit diagram.
Try switching a different mic, sometimes the transmitting wire comes loose inside the connector. If you are handy enough, you can even unscrew those two tiny screws on the end of the mic cord and see if a wire is loose and if so, solder it back into place.
