There are 2 possibilities:
1. Move to quiet neighbourhood.
2. Find noise source and get rid of it.
No radio mod gonna help you.
I would start with house you live in. Cut the power, check on battery if noise disappears or not.

Noise source is close to house,drive a few hundred ft and it will disappear,have tried battery/isolated from own main supply,leaving it off a few hours to allow any capacitors in house to dissipate aswell Chris.Some radios not as bad as other's,radios with lcd displays like Lincoln + Ranger 2950 etc seem worse than analougue needle on meter,maybe just too sensitive for modern psu's that surround us.

Very annoying when you pick up unusually high interference wise/bloody chip pan,but whats the point when they are firing microvawe signals/PLT etc,still take the same tax/vat on new radio purchases,even with no guarantee you can actually hear anything,even when it is set up right {bnghd} rant over.
