Dave, make sure that the preamp is engaged on your KX3. If the preamp is off and you are receiving on a quiet band, you'll see "stuff" that would normally be covered by the band noise. Turn on the preamp, and the artifacts that you're seeing should be pushed below the noise floor of just about any band.
