[Elecraft] Noise blanker

[ab2tc]

The noise blanker in the K3 is truly astounding. I find that to be really
effective on power line noise, I have to use the DSP portion of it. The IF
blanker alone will not do it. Unfortunately the DSP blanker distorts really
strong signals (say S9+10 and above). So if I listen to a group with some
very strong and some weak signals, I have to turn the blanker on and off all
the time. Could this not be achieved automatically? With a really strong
signal in the passband, there is no need for noise reduction of any kind, so
why not turn it off?

I don't yet have the HAGC modification. Is it possible that the onset of
distortion coincides with the onset of HW AGC action? If I could get another
20dB of distortion free noise blanker, the problem would be greatly
diminished.
