How to fix common CB radio issues?

Squelch and Noise How to Find the Right Level

Control of Squelch The squelch function mutes the radio when there is no signal so you don't have to listen to static all the time. To make changes set the squelch level just above the level where the noise stops. This setting helps get rid of the background noise without blocking weak signals from faraway stations.

Noise Blanker and ANL (Automatic Noise Limiter) Most new CB radios have built in features that help reduce interference. To cut down on engine noise and electrical interference especially when the car is moving turn on the noise blankers and ANL.

Problems with coaxial cables the problem that is often missed

Finally let's talk about the coax cable which is often forgotten. It plays a very important but often unnoticed role in your CB setup.

Checking the Cable Your coaxial cable can get worn out just like any other electrical part. Look for cracks burns or kinks that could mess up the signal. If you see any of this kind of damage you may need to replace it.

Check the Connector Make sure that the connectors on your cables are tight and free of rust. Boiling water and vinegar can clean up corroded connectors but the best way to make sure they work for a long time is to replace them.

Cable Length Believe it or not the length of your coax cable can affect how well the signal works. If you can keep it around 18 feet long. This length is usually best for tuning to reduce SWR problems.

Practice Routing Don't run the coaxial cable near things that can cause electrical interference like engine parts or other wiring. If you keep it away from heat and interference you can keep the signal strong.

Being aware of and taking care of your coaxial cables can fix a lot of strange problems and get your system back to its best performance.

By doing these things you now know how to deal with and fix common CB radio problems. You'll be happy when you can talk to each other easily and when you can solve these problems on your own. Keep your setup well maintained and enjoy the ride!
