[Elecraft] P3 level accuracy

[Brett Howard]

My XG-2 is within 1dB when tested on a recently calibrated spectrum
analyzer with MUCH less than .1dB error.  More error was introduced with
the N to BNC adapter than by the analyzer in this test.

My P3 however is quite a bit off (similar to yours) but I don't remember
the exact values.  I'm looking forward to a calibration routine.  It is
something that has been planned but other more important features such
as fixed span tuning are ahead of it.

For what the P3 is intended for it does its job very well.  Once the
amplitude calibration is in place it will do beyond its intention very
well.
