[TenTec] Orion RF level tutorial needed

[Gary Tuck]

I just loaded 1.372 again to see if my assessment of the tradeoffs have 
changed.  I like the adjustable RF gain but am not fond of the delays 
you find on some functions nor the little audio glitches when adjusting 
AF, Cut or PBT.  1.371 seems to offer a more predictable and dependable 
experience.

Anyway,  it appears that when the NR is engaged that the Threshold--as 
adjusted by the RF gain control--drops to some lower value and noise 
may come up.  Is that right?  Seems as if the NR function and Threshold 
adjustment of IF gain cannot be used at the same time.

tnx, Gary W7TEA
