[Elecraft] KX3 Filter Blow-By

[M5FRA - Colin]

Jim, can't say that I have noticed the problem you mention, in fact I 
was thinking the KX3 was handling close in strong stations better than 
my TS-590. I do have the roofing filters and also am tending to use 
bandwidths of 100-300Hz.  There are a lot more key clicks, buzzing and 
general noise these days, my guess a lot is from incorrectly setup 
amplifiers/rigs with bad CW waveforms or both!
