[Elecraft] RFC1 and RFC2 on KSB2

Maybe it's just me, but I found RFC1 and RFC2 on the KSB2 to be very tight
fits. They are both quite stuck between the crystal and resistor pack. That
would normally not be a problem, but allthough the manual says to 'try to
avoid scrapping the wire', one of my RFC's apparently did not come through
unscraped. After mounting and checking for continuity, I had the good sense
to check for a short to the crystal can and Bingo! Shorted!
I might have made some more room, if the manual had warned that the crystal
and the resistor pack should have been soldered as far away from eachother
as possible. I'm not sure, as this is my first KSB2. I'd rather not start
messing with them now they are already in there.
If it's just me, no problem, it's fixed.
If it is more common, maybe it would be a good idea to have the manual
check for shorts between the RFC and the crystal. I'm not sure how long it
would have taken me to find this one if I hadn't done it right away. From
the schematic I'd say it would have introduced some weird filter switching
problems....
