[TenTec] [Orion] Orion NB vs NR

[Pfizenmayer]

Another tip on the firmware NB in the main receiver (NOT the HB) - on some 
sorts of noise go into FILTER and force the roofing filter to 6 khz or 20 
khz - it can make a huge difference in effectiveness. I stumbled into this 
one day when I noticed the SUB receiver NB seemed much better on some noise 
than the MAIN rx NB.


The hardware noise blanker HB uses a separate signal path  than the dsp 
based NB.  It utilizes a special IC designed for impulse noise blanking 
along with diode gates.
