[Elecraft] New PX3 - question on a signal that doesn't move

[Thorpe, Jeffrey]

Probably a dumb question. New to using pan adapters, and just got my PX3 put together.

I hooked it up to my KX3, tuned around on 40m (using a home-brewed AS-2259 NVIS type dual dipole for 40m and 80m) and I get really strong signal indications close to 19khz both above and below the center frequency on the display. It doesn’t matter where I tune in the band. If I adjust the scale, the signals stay at the +/- point of about 19khz. They appear stronger than any other signal in the display.

I am running the KX3 off internal batteries, and the PX3 off a LiFePO4.

Are these signals from something outside being picked up in the cables between the KX3 and PX3, a problem with the PX3, or something else (like, maybe, me)?
