[Elecraft] PX3 Problem?

[Dale Boresz]

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.
