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.
