This is my first post. I'm new to the CB world. I got a Uniden pro505xl off amazon for Christmas. Set it up on my truck with a 3 foot firestik, 18 foot coax. For power I used a fuse tap, then grounded to the frame. I had trouble tuning at first, but after raising the antenna a little bit I have an SWR reading of 1.7 all round. Here's the issue, when I put my truck into reverse it makes a ton of white noise!!! Also, I'm getting a whine from it as well coming from interference with the alternator. This is really bugging me. I checked grounds, they are okay and just for kicks I put a second ground onto the antenna mount going to the frame of the truck. Please Help!!!
