[Amps] Hunter Bandit 2000C, arcing in the tuning cap.

[Tom Osborne]

I had an antenna tuner here that would let the SWR drift when tuning up 
and sometimes arc.

After all sorts of trial and error fixes, I finally loosened the lock 
nut on the end of the tuning caps and tightened the screw. Eliminated 
the problem and now all is good.  The rotors were just too loose and not 
making good contact.  73
