In addition I believe I remember a post that says the tuning capacitor may
have two peaks, one slightly less than the other. If you use the weaker of
the two peaks the transmitter will not align properly.
I had some similar problems on 30 and 17 meters and found two capacitors in
the premix filter had bad solder joints. Same symptoms as your C5 problem.
After hitting them with the soldering iron one more time everything started
working properly.
Also look at the article on the Elecraft web site on Cheap and Dirty Signal
Tracing (look under the tech notes menu item). It does help rule out
problems if you follow it, and it is certainly cheap!
Good Luck.
