Using ladder line like that often introduces RF into the path. It might
help having an external tuner, but here's some other things you can try.
First, you don't say what rig you are using.
If you are using one of the Kenwoods i.e. TS2000, possibly the TS-570 etc.
and you haven't modified the mike connector, put a piece of wire from the
bottom screw of the mike case to the side of the rig where the mobile
brackets attach.
Second, attach a quarter wavelength counterpoise to your ground and run it
around the perimeter of your shack.
Third, if you still have RFI look at
