[Elecraft] Unusual P3 behavior ?

[Phil Hystad]

Fred and Bill,

Thanks for your answer -- I think that is probably the issue.  I totally forgot about the ref lvl setting.  Of course, that delayed behavior would have still confused me a bit.

Thanks.

If I was on 20m during the day with the REF LVL set at the baseline, and then go back to 20m at night [when the band noise is a lot lower], I'll see the spectrum trace and WF for a second or two, and then it goes away and the WF is black.**  Conversely, if I set the REF LVL on 80m during the day [when the band noise is low], and then come back to 80m at night, the trace is elevated above the baseline and the WF is fuzzy white.  Just leave REF LVL up on the screen and adjust it.
