[Elecraft] P3 failure?

[Chuck Guenther]

I was operating today, and noticed my P3 display showing no spikes or 
noise level, and the waterfall portion of the display is pink.
When I try to adjust the REF LVL, I get an indication of "nan" instead 
of some negative dBm level.  I've cycled the power on/off on both the K3 
and P3, and even re-booted the computer, with no improvement.

TNX for any help on this,
