    Thanks. Perhaps that would have been more appropriate than picking up from the cigarette lighter, but that was closer in both distance and time. Appreciate your help

Take power off the fuse for the Radio. Use the cold side. EG: the side with no power when the fuse is removed. You can use the hot side if your DB has a fuse in line. Or you can slpice into the radio power line.

You can hear people talk but when I pick up mic they can't hear me unless parked. whats wrong?


I would suspect alternator, electric fuel pump or relay. Either way it must be electrical noise.

  • I would check that your grounding straps are in place from motor to frame.
  • You may consider installing a rf filter on alternator which consists of a capacitor, auto parts store sometimes carry them.

Bought radio at Hamfest. Hooked it up worked flawless. Great ability to fine tune signals. Let a tech talk me into installing echo board. He tried two new boards. They wouldn't work. Told him never mind ,...


The guy who was really not a tech probably didn't hook the mic wires back to the mic jack correctly. that will cause the radio not to TX or RX.

Next time make sure the tech knows what he is doing, and check on line for cb radio shop blacklists to make sure that one isn't on the list.

This guy owes you either a new radio, or pay to have that radio repaired.

If both echo boards didn't work, he doesn't know what he is doing, because he put them in wrong.

I need diagram on how to install or wire my CB IN MY CAR. The CB is already connected to a 400 watt linier that is mounted to the bottom. Mounting,installing not an issue. Proper wire and antenna hook up...


The CB radio its self just needs to be connected to power, and the antenna connected. You need to use at least RG-8x coax or you risk it frying from the extra power from the amp.

The radio needs to be attached to the amps input, then the antenna needs to go to the output of the amp.

Then most importantly the antenna must be tuned to lowest SWR. It must not exceed 1.5 and even that is pushing it.

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.

My neighbor's cb radio comes in on several frequencies.


All electronic devices are required to receive unwanted interference but not cause enterference them thats the best answer I can give you. Your neighbor might be operating with greater than 4 watts allowed by the FCC for citizen band transceivers.

Radio shack cb radio 21-1703


OK. I do not know the exact number for the diode off hand, because I don't have the same radio in front of me. On most cb radios, this diode is usually located on the component side of the pc board, close to where the positive lead solders to the board. Most of the time when it burns, it just becomes brittle.

If you do replace it on your own. The diode is called a rectifier diode, which you can pick up at radio shack or at partsexpress.com. The part number is between 1N4001 to 1N4008. When installing be sure to observe polarity, making sure that the side with the silver band is facing the direction of the arrow.

If I can help anymore, please don't hesitate to ask.
