[Elecraft] K3 APF Adjustable Q

[Steve Ellington]

If I had a choice between variable center frequency and adjustable Q, I 
would choose adjustable Q.

My logic is: The center frequency automatically follows the sidetone 
frequency so I have no need to adjust it however the fixed Q has a bit of 
ring and at times I would like to back it off (widen) it just a tad.

Otherwise it's a HUGE improvement, sounds great and I wish to thank those 
who made it possible.
