[Elecraft] P3 Anomoly

[Jim Miller]

I'm finding my P3 is doing something new and unpleasant. It keeps dropping
it's senstivity after a few minutes. The noise level is visible normally
above a -140db threshold on most bands but right now I need to move the REF
LVL to -160 to show noise on 20m. If I turn it off and on again the noise
level sensitivity goes back to 140ish as it should.

I've not figured out what triggers this behavior.

Anyone else?

FWIW, setup is K3/P3/KPA500 (currently in standby). K3 in Test mode.
