That is probably caused by averaging.  I believe that with PowerSDR,
whenever you tune the K3, the old spectrum is still present in the
averaging memory and you have to wait an averaging time constant or two
to see the new spectrum.

The P3 automatically re-sets averaging (and peak hold) whenever the K3
frequency changes.  So you see an un-averaged signal immediately after
tuning and then the signal smooths out as the averaging memory is
refreshed.  But at least the signal never goes away.
