I have a Kris XL-40. Solid radio, good reports, but shelved it due to being too sensitive to RF from truck. Kind of a splatter box, bleeds over adj. channels. Could make good contact with the engine off. Needs a RF filter. CB tricks may have some information. I had found an old list of tunes and mods for a lot of radios, the Kris was there, but don't know where it is now.
