lot of possibilities but the one I'm thinking of is , did you buy this radio new or used. If you bought it used there is a chance that the person that owned it last broke it and couldn't fix it so he sold it to you. Now you see the problem and want to fix it but don't know where to start. ok ,here goes. Check your antenna system A bad ground will will give you this problem.Make sure you SWR is low. then if that doesn't cure it open the radio and check for bad solder joints. Flex the radio and see if ti comes on. Check to see how it will cost to fix it ,then go buy another one.Only if no other options work.
Are you using the noise blanker? Are you also finding noise on regular AM radio in vehicle? How good is the connection on the coax?
How good is the antenna ground to chassis? How good is the antenna?
If you address the various sources of general RF hash that would also aflict the AM reception in your vehicle, that would be the first thing to address. It would probably be a good idea to use some contact cleaner or LPS1 and spray down the switches and controls. I know on one of my own that the dirty contacts are enough to kill off reception.
If these things do not improve it, and you do not mind going into the radio- in the reciever stages are a number of 1N60 diodes, and they have a nasty habit of becoming leaky and noisy. Replacing them should help quite a lot if nothing up to this point has.
You need to buy an antenna that is designed for use with a CB. A couple of good ones are the Wilson 1000, Wilson Lil' Wil, K30, K40. You will only pick up "everything" within the 40 channels with that radio.
