[Elecraft] Attenuator and RF Gain Settings

[Lyle Johnson]

In addition to the IF and DSP noise blankers, the K3 incorporates a 
third feature to help deal with impulse noise.

One of the AGC parameters is CONFIG: AGC PLS.

"nor"  is used to activate a fast-reovery AGC algorithm if the signal 
that activated the AGC is above a certain dynamic threshold and lasts 
for less than a specific time.

"OFF" allows the AGC to be "pumped" by pulse-type noise.

Like any system that deals with suppressing pulse noise, the overall 
receiver gain is being quickly modified, so there may be IMD or other 
effects.
