Hi Don,

Yes, I have a copy of the manual but it doesn't discuss linearity.  Just set 
the endpoints and not much else.

As far as trying to move the plates of the tuning capacitor closer together, 
I'm almost afraid to try that as there's minimum clearance as it is.  I 
might be able to squeeze 0.010" or so, but not sure if that would be enough 
to matter.  Maybe I'll try it, though.

Thanks,
