Interference

It's likely ignition and fuel pump noise. For starters, you can install a noise filter on the power line feeding the radio. Radio shack sells them. It may have some success, or it may not. After that, it's a matter of hunting down the culprit and filtering or bypassing it to eliminate the noise, which is no easy task. Another easier way to do it is to buy a DSP filter, which will filter most of the noise out without all the headache. They're a little pricey, though.
The 501 really isn't that much of a radio )-: I'd be very surprised if the noise was coming through your power line , in most cases , it's just not that easy )-: more so then not it comes from the antenna , you can do a test with your car running and your radio on , unscrew the coax from your antenna to the radio , noise goes away ? then you know where it's coming from , you can do a lot of things as Mole dude suggested , but i really don't think that 501 has very good rejection what so ever ......if it were me , I'd just kick it up a notch and get a slightly better radio with better noise blankers and anl's in them such as a cobra 25 or 29 , they really do knock out most of the serious engine noise that goes through the antennas and it is a lot easier then trying to sniff out the problems from the sourses. Good luck to you and welcome to the forum.
Thanks guys, I got the radio at an auction for $1 so I wasn't really expecting a great rig just something to play around with,i didn't really put much money into it so ill just try to play around and fix it. Thanks again
What type of car is this? Some of the Ford vehicles are noted for such problems. I agree so far with the replies.
If possible move the antenna to diffrent locations and see if that helps, re-route your coax or coil up any extra coax and move the coil to a diffrent location also.
