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.
