I have a K2 which has a strange quirk, it has developed a "thump"

QSK. Very annoying, and when trying to DX at fast cw speeds, I
can't tell what the DX op is sending. However, if I change the T-R
delay to .01 it doesn't appear.
I hear more of a thump in QSK when I have headphones plugged in to
the speaker jack. If I plug into the headphone jack, there's no
thump. I think the caps across the headphone jack have something to
do with that.
There is a mod to get faster QSK performance from your K2. It's on
the Elecraft site, or look in LA3ZA's mod site.
