West Mountain Radio, maker of the Rig Runner, recommends against using
the pins in the strongest terms on its web site. The issue (they say)
is that the pins have a nasty habit of coming out and falling into
places they should not go, where they can cause short circuits and
extensive damage.
I just squirt a bit of hotmelt glue in the hole once I've assembled them.

Hi Brett,
What you describe is commensurate with the PowerSDR Display AVG Mode being
enabled. If AVG Mode is off, the displayed panadapter signal amplitude
will not decrease as you tune the band. The displayed signals are real-time
with a display frame rate adjustable to 50 frames per second.
Yea I kinda noticed that... But I felt like I was about to enter into a
seizure when its real time...
I'm not sure what would work better but two interesting things to see
would be either have the display go into real time mode during a QSY or
have the display freeze the averaged data during QSY.
