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.
