CB Base Station picking up electrical interference
I have my CB all installed and ready to go as a base station here at my house. But all I get is electrical noise when powered on and I have to turn the squelch way up high just to get it to go away. I've done radio checks and I can't pick the radio up from my car. I even tried my handheld CB and sat right next to it and received a very weak signal. I have even moved the base station a few times to see if that would work. This is a brand new radio which replaced a broken one (actually broken for sometime) but I never had this issue in the past. Now I have it connected via DC-AC adapter, could this possibly be the cause?
Re: CB Base Station picking up electrical interference
I dont know what AC DC adator your using. you should look into a 12V power supply. or plugging that into a RF canceling power strip, like a monster power strip. TV's that are on or other appliances may cause high noise levels on the CB, make sure your coax is good, your antennas good, and all jumpers are good. its hard to tell with out looking at it, but do a quick once over of the system.... you are using a base antenna right? if not you need to create radials for a mobile you plan on using for a base.
Make sure the connectors on the coax are all on right, this causes problems a lot of the time. sometimes even brand new coax have bad connectors installed.

Inverters are full of diodes and diodes are extremly noisy devices. Also the filtering in CB radios is not the best as manufactures try to keep costs down to compete. Try unplugging the antenna from the radio and see if the noise stops. If it does not stop, then buy an inline filter to go in the supply to the radio and place it as close to the radio as possible. If the noise DOES STOP when the antenna is unplugged then it is coming in through the antenna and there is not much you can do but maybe buy a much higher quality radio with better filtering. You might try moving the antenna. Magnet mounts are not as good at blocking noise as high quality permanent mounts. Work to get your SWR as low as possible. Use high grade low loss coax from the antenna into the radio and use high quality connectors like the Amphenol brand. It takes time and effort to solve this type problem and some times nothing works.
tripp lite, pyramid, and others make powersupplys for home use. for that radio. 5 amps should be enough.. but you may find a better deal on a 10,12- even 20 amp go with it.. if you need help call us would be glad to assist.
NOT AT ALL .....IF YOU ARE TALKING ABOUT A BASE STATION ANT.....FIRST GET A GOOD ANT ......GET THE MAST TO PUT IT ON ..1 OR 2 MAST.. YOU MAY WANT TO USE SOME GUIDE WIRES..IT'S A GOOD IDEA......MAKE SURE TO GROUND THE ANT..WITH A LIGHTING ROD THAT GOES INTO THE GROUND.....GET SOME BASE STATION COAX.........GET A SWR METER A CHEAP ONE FROM RADIO SHACK HOOK EVERY THING UP CHECK YOUR MATCH WITH THE METER AND YOUR GOOD TO GO........WHERE YOU PLACE THE ANT ON YOUR HOUSE WILL MAKE A BIG DIFFERENCE IN HOW THE ANT WILL PERFORM PICK UP A CB RADIO BOOK @THE LIBRARY OR LOOK INTO ONLINE
