[Elecraft] P3 Vs. K3 Noise Level

[Brian J. Linn]

All:

 

Even after considering the P3 manual (page 21) and with AGC off, I find the
following difference in S unit measurement odd.

 

 

Band  P3    K3

75m   S5    S9

10m   S0    S2

 

 

I'm trying to ascertain an accurate noise level reading at my QTH.  Does
anyone have any thoughts on the degree of difference in these readings?
