[Elecraft] P3 "Tuning Noise"

[Grant Youngman]

What you see in the display when not tuning is the time-averaged noise (or signal), depending on how you have the averaging parameter set. When you're tuning rapidly the P3 can't average, so the level appears to rise.  It's rising toward the actual peak noise level.
