View Full Version : cb radio problem

Hey guys I am having a problem with my cb radio i just picked up. When I turn it on when the truck is not running it works fine. When I turn it on with the truck running I get a s**t load of interference. I tried about four different grounding points and even tried to install a noise reducing filter. I even ran a direct power line from the battery, to avoid going throught the fuse panel. This is the second cb i have tried to install in my truck and the same problem is occuring with both. Any suggestions would be greatly appreciated.

do you have a stereo amplifier?

What kind of noise is it? whine or tick, tick, tick tick? Does it rise and fall with the engine's rpm? Did you match your antenna?

plug wires would be my guess as well use.A die-electirc silicone grease on the boots at both ends.

You have two options. #1, buy a noise filter, they're about $10 at Radio Shack...the other option...adjust the squelch. This might sound incredibly simplistic and no idea if this applies to you or not, but I've met some first time cb users who didn't realize that you can adjust the squelch to no-noise, then get a radio-check from a friend, all will be well.

Check your plug wires; "cooper" if they are, the only way to get rid of the static is to get rid of those nice clean sparking wires and got to a 8m.

Just what I need, another wagon!
