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.
