[600MRG] Best receiver settings

[Eric NO3M]

couple other points i forgot:


Observations on noise and initial gain adjustment should be done near 
solar noon so any changes from say adding a choke, etc., can be 
observable.  When atmospheric noise starts to set in, adjust the gain 
(preamp/att) as needed

Some may be wondering.... whats the difference between adjusting the "RF 
Gain" (ie. IF gain) and AGC doing the same thing....

Unlike older analog rigs where AGC was implemented in the IF, most 
modern hybrid rigs (like the K3) that are really an SDR w/ an analog 
front-end, the dominant AGC is performed in the digital (DSP) domain.  
In the case of the K3, there is a hardware (IF) AGC that is only 
triggered under extreme signal levels (S9+30??) to limit what makes it 
to the second mixer and ADC.  Therefore, under normal conditions, the IF 
should be running at full gain and where it's IMD characteristics are 
optimal.
