[Elecraft] XFIL on K3

[Nr4c]

Don, no apology necessary. But this is one item I was cautioned about before I purchased. 

I didn’t see your response until after Dick had responded. I’d have been confused!

I’ve  ewww had my K3 now for ten years and a local guru. But I can close my eyes and Stan at any page in the manual and find something I don’t know/understand.

There is a similar discussion near the top of page 7 of the K3 "Installing Crystal IF Filters" document and the bottom of page 77 of the K3 owner's manual.
