I have developed a new problem with my PX3, which has been quietly sitting in a case for the past 6 months.



Whenever I tune across the display, there is a slowly rising spike at the base frequency (for instance, in USB mode this spike adheres to the left hand edge of the bandpass indicator on PX3 screeen), takes about 2-3 seconds or so to increase in intensity, and then dwarfs any of the signals on the band.  This spike tracks across as I tune; it is there whether or not the antenna is connected.  I can tune to stations and hear them fine, but the display is barely usable because of this very tall spike that won't go away.  I reseated my cables connecting the PX3 to KX3, with no change in behavior.  I have no other cables here to swap them out, and am kind of stuck



I have updated b both KX3 and PX3 to latest firmware, with no change in behavior.



Any thoughts would be GREATLY appreciated.
