[TenTec] Centurion is on the Fritz

[Bob McGraw - K4TAX]

Remote tuners are mostly like helicopters.  I find they have too dang many 
moving parts expected to move at the correct time and in the correct amount 
to be reliable.  Thus more crap in line means more likely hood of failure 
and problems.

P.S.  Oh yea, I'm a fixed wing pilot.  CFII ME - Thus I prefer the fans 
either out front or to the port and starboard, but never on top or behind.
