[Elecraft] PX3 Amplitude calibration

[dmb at lightstream.net]

With the same Span settings, my PX3 consistently indicates signal and
noise floor levels about 10 dBm higher than my P3 (or a number of other
panadapters on SDR radios).

I've looked through the manual, and see that there is an amplitude
calibration for transverters using MENU:XV Gain. However, I see no way to
calibrate the level for non-transverter use.

The P3 has a menu option: Lvl Cal for this purpose, but from what I can
see there is no parallel for the PX3.

Am I overlooking something?

tnx and 73,
