     I think it must be something like that because I am 
pretty sure some of the problems are fairly recent.  I am 
especially suspicious of the trimmer caps but there may be 
something else associated with the bands having the 
problems. I've done what I can about the bandswitch, its 
actually pretty clean. One would think that the problme 
being only on some bands would help isolate it but so far 
its not been helpful.
