I have a Emperor TS-5010. It works great, but for some reason when i have a high noise level i can not squelch out the noise. I can turn it all the way and i still get the noise. It has a Loc/DX on it and if i push the Loc than i can not pick up stations in the distance. Can someone tell me if i am not working it right? Or does it need to be worked on. Any help at all?
