[Elecraft] New K3 Firmware: Pileup-inspired AGC changes

It has nothing to do with roofing filters. The roofing filters are 
critical to the K3's design; they keep large signals from getting into 
the I.F. strip in the first place.

The AGC changes we're testing are intended to reduce the modulation 
effects that DSP AGC creates when multiple, closely spaced signals are 
present within the DSP's passband. Early reports suggest that it's 
working.
