Hi, 1) Get an ohm meter. 2) open the mic 3) unclamp the mic cord at the plug and slide the plug case up the cable to enable you to see the wires soldered to the plug. 4) use the ohm meter to check the wire continuity by checking each color wire one at a time. The meter should have full deflection if the wire is OK, make sure to wiggle the wire to make sure it is not intermittent.
Personally I would just change out the cord. If it is going the rest of the wires are going too.

Hi sqa, my name is John. Welcome to FixYa. First thing to do would be is check your antenna system. Check that it is grounded good, like to the body of vehicle, and that nothing is blocking it. Next, check the coax cable, you will need a ohm meter to do this. Put it on the OHM scale, then with one of the probes, touch the center wire of the coax connector, while touching the other probe to the outside of the connector. If you get any kind of reading on the meter, the coax has a SHORT in it. If not, then the next step would be to check the SWR on the antenna. You can get this done at any locale CB shop for free. Try all these steps and still no solution, let me know and I will be glad to help you. Thanks for choosing FixYa....John
You will likely need different connectors (or adapters) at both ends of the cable, but the cable itself should be fine. Just verify that the cable is 50-ohm (it should be marked on the cable) before you start running the CB through it.
SWR is key. A poor SWR can result in RF power backfeeding into the radio and can show up as distorted audio strange indications on displays, etc. Your 1.1 : 1 - 1.5 : 1 SWR ratio is very good, but double check antenna connections and make sure they're good and made up tight. Inspect the soldered and crimped on connections for evidence of breaks, etc. Pay attention to the condition of the ground point at the antenna end - clean any rusted metal to ensure a solid ground. Mag mounts won't have a ground point - so try to be sure that the base is on a relatively smooth, flat surface,
The next thing to check would be the mic and associated connectors & cable. Repair any suspect connections. Finding nothing, you might want to ring out the cable itself with a tester or better yet, and ohmmeter. replace the cable if any conductor has broken at a point where cutting it off would leave the cable too short to use. If it's broken near the ends (a common failure point) simply cut off the bad part and reconnect the mic or connector as needed.
You might even try a new mic if you think the original is no longer functioning correctly.
That's about as far as you're going to get without needing specialized equipment (not to mention an FCC license) to dig any deeper and make repairs.
Hopefully, you'll find the problem without needing to go further. Good luck!
As for me ,the Wilson 1000 or Wilson 2000 are the best mobile antenna for a mobile. I have out talked a lot of base antennas with them, just put it on the top of car in the center or trunk, or middle of cab of truck, with a good SWR and you are talking and receiving. great antenna. ...hope this helps..
you need to check the connectors on the coaxial cable that plugs into the radio and antenna with a resistance tester from the pin in the center to the outer case there should be a resistance of infinity any reading on the meter says there is a short circuit in the cable and u will not transmit make over the connectors on both ends of cable make sure the center and outer wires do not touch
The end without a connector was once attached to an antenna. You need a proper antenna in order to use the radio. If you were to buy a new antenna, it will come with a length of cable attached. Even if you were to buy a new antenna, don't expect good performance from the radio unless you get the antenna properly adjusted. Yes, it will work "out of the box", but probably not as good as it could. There is a device called an SWR bridge, it's used to measure the SWR and the user then adjusts the antenna for the lowest reading by trial and error adjustment of the antenna.
