[Elecraft] [KX3] Key Clicks

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.
