[Elecraft] P3 lvl cal?

[Matt Zilmer]

Hi Alan,

I would guess that running Peak on the P3 and having the S meter on
the K3 set to PEAK ON should give roughly the same results.  Correct?
Or does the same discrepancy you advised below exist?  Peak and PEAK
ON similarity is what I'm seeing here on the K3 / P3.
