You have an antenna problem. Get a good antenna, such as a Wilson 1000 & use the SWR function in the radio to tune it. Wilson antenna come with tuning instructions.

fiberglass,no ground plane. Did you use the meters on the radios to match your antennas or a seperate external antenna.you might have to run your own coax and hook up a mirror mount bracket and put your favorite antennas on them then match them and ground them to the chassis use common sense to show you what to do next and you should be getting out great. Sometimes people change the antennas on those trucks with built in antennas and don't realize that the coax has just fallen out of site into the body somewhere. thats why I said install your own.

Best way to locate the problem is connect the radio to a Dummy load known to be good====if swr still comes on it is in the radio--if not in the antenna system.

Check SWR with a meter, if its 1.1 to 1.5 then its fine no matter what the light says. The light can be adjusted inside to not light up until its very high(Its adjustable with a Variable knob inside) Get a Cb shop to check it out. I'd go for LIL Wilson 500 or 1000 antennas, I hear they are superb.

I have a Uniden PRO510XL radio and a 48" single


then the antenna needs to be moved. antennas have to have a ground plane to get correct swr below 3... or there may be a bad ground. try moving antenna @ different angles to see if it changes swr's or even opening the door away or closer to the body will make it change. also check the insulator it should be on top. call if you need help

Uniden pc78elite antenna light


What kind of antenna is it? Have you checked your standing wave? To do this process you will need a field strenth or a SWR meter to do it,would be cheaper to have it checked at Radio Shack or you can buy one,and do it yourself. Some radio antenna light come on when transmitting,....hope this helps....

My grant has good mod on sideband but when i transmit on am i get a squeel like sound coming in with my voice but the squeel is louder then my voice. could it be a bad shield on my hand held astic power...


If you have talk back, that most likely why you have feed back. If its on a switch, turn it off. When it was put in, it was done too loud. You can also turn down the gain on the mic.

Uniden 520xl makes humming noise when mike is keyed


if you have a power mic , you might have it turned up to high. next make sure you have a good ground on your antenna. if that is ok and you still have the same problem have the swr checked. this should fix the fm radio noise.

Matching Antenna, or ??????


If the antenna is tunable, you definitely need to start out by having the swr set properly on the antenna. Also, make sure the plastic ferrel, (the small round white piece) is between the top of the antenna bracked and the antenna itself. It is there to make sure the antenna does not ground out to the vehicle. If the antenna is grounding out, it will be like no antenna at all. I have also had a few customers that have had broken coaxes straight out of the factory package on cheaper antenna setups.
