[Elecraft] K3 QSK CW Audio Dropouts

[Steve Ellington]

Depends on the bug. With my McElroy stream I had to add a 1uf capacitor in
parallel with it. After reducing the dit gap to compensate to the keying,
it sounds great.
On my Vibroplex Presentation, no capacitor is needed and keying is perfect.
I noticed the same thing on my old K3 and a few other rigs. I suspect it's
something to do with contact bounce due to variations in the dit spring and
how different rigs react to the bounce.
I have to remember we are no longer just keying a circuit rather we are
keying a computer from another planet. :*)
