[TenTec] ORION2_HW-NOISE_BLANKER

[Pfizenmayer]

George - There is a trick whick may or may not nelp your firmware dsp 
blanker (not HW blanker)- I operate mostly cw with 300 hz filter and DSP 
even narrower  and on some noises I find that forcing the roofing filter 
bandwidth up to 2.4 or 6 khz really makes it perform. Of course you are back 
to the same problems if you have strong signals inside the 6 khz bw.

 Anyhow I stumbled into this one day when I noticed the NB  in the sub 
receiver seemed to worke pretty well and on the main did nothing. The sub of 
course has a wide if for the dsp nb to work on.
