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.
