Don,
How about a single capacitor (1-4 pF) from the junction of the crystals and
the L33 inductor as in
http://www.ac6rm.net/mailarchive/html/elecraft-list/2005-08/msg00562.html?
Does that create potential stability problems also?
I've got this link on my K2 mods page and just wanted to make sure I can
recommend it and keep it there. I have never had any problems with BFO range
myself so I have no personal experience with this myself.
