[TenTec] Orion2 auto tuner

[Bob McGraw - K4TAX]

My experience is that auto tuners indicate TUNED when they attain the lowest 
SWR regardless of the value.  It could be 10:1 and if that is the best it 
can do then it is TUNED.  Although most would not consider this acceptable.

I understand that most think they should be able to attain a 1:1 under all 
conditions.  That is not generally attainable and is largely depending on 
the range of the tuner vs. the applied load.

My solution is a 238 tuner after the amp.  Using an antenna bridge to set it 
up, it will match most any normal antenna that I can throw at it.  I gave up 
on narrow range auto tuners long ago.
