No problems, mate.  Pardon my poor English, but us VR2s are like that...  ;^)

Comment based on fact that C31XR/single_feed isn't as simple as different
tip lengths & different Q coils as C31XR/separate_feeds.  Somewhat different
beast & since nobody pointed that out, I could not let it go as Force-12 was
not being treated fairly in some folks' posts, IMHO.

Now, where did this start?  N7WA was having some problems with reasonant
frequency on 21 Mc.  Hmmmm.... Dink?
