Well, so must I be, since I use both the swinging-link and the series cap.

Actually, on certain portions of the 75M band, with my HB unit, I find it 
easier to tune-up by slightly decoupling the link.  On 40M and 160M, I'm 
tightly coupled.

Probably a feedline length issue.

Interesting that the fellow that started this thread said his feedline was 
multiples of a quarter wavelength.  On what band?  Electrical feedline 
length will change within a band.
