I'm going to jump in here with my 2 cents worth, because I would REALLY like Elecraft to clean up
the QSK on the KX3.
Recently I've been noticing annoying pops in the speaker when sending CW. Maybe they've always been
there. I never noticed them before. It's been a while since I installed firmware, so they must have
been present but ignored for a while at least. They really jumped out at me when I started playing
with a new sideswiper paddle last week.
The pops happen at key-up, not key-down.
They are heard with the internal speaker and also with external speaker or
headphones.
The pops are present when using the internal keyer, with an external keyer, and
with a hand key.
If I send a series of dits while varying the keyer speed (with external keyer), the pops are most
pronounced around 19 wpm.
My KX3 is S/N 77, on FW 2.11.
Dual watch is not active. RIT and XIT are off.
My AFX mode is DELAY.
My QSK delay is set to 0.01 to try and reduce the QSK thumping.
