[TenTec] Orion no Tx, no main Rx

[Martin AA6E]

Hank,

Warranty is long over!  I appreciate all the friendly suggestions.  It 
may be time to flip the firmware.  I don't see how my symptoms could be 
firmware, since resetting with the "battery reset" and user memory 
reset, etc. should restore everything to initial conditions... Or so 
you'd think.

I can tolerate 2.05x for the most part, and it does have some 
advantages.  The problem that bothers me is that the v2 SP really does 
not work correctly - does not increase talk power as it should.  I might 
try it just to see if it fixes my current trouble, but then I might 
revert to 1.371 or 1.372.
