I have been using 0 also. It seems to work. Since the NR has been
temporarily turned off, it may be improved when it returns.

I have never found the IF NB to be necessary -- the DSP blanker has done
the job for me with all the noise I've encountered. The IF blanker works
pre-selectivity, which makes it effective against very strong, very
short, noise pulses. The downside is that it can be affected by strong
signals outside of the passband. This does not happen to the DSP
blanker. The only thing I've noticed is that at higher settings (I use
T2-6 and T2-7 a lot), it makes CW signals sound like slow-starting
crystal oscillators.

I'm a CW guy, but I did some tests with knowledgeable SSB operators and
ended up reducing the two lowest bands all the way (-16db each), the
next one -6 db, and then increasing the top two by 4 db. This was with a
Heil HC-5 element. I don't know if there was any output from the mic in
the lowest ranges, but those frequencies aren't helpful, so I took them
out just in case.
