Bill,
With the NB, it will often help to *increase* the RF gain or turn on the
preamp. The noise impulse must be above a threshold before it will
trigger the blanking function. Keep in mind that setting the NB so the
blanking pulse is wider may result in distorted signals. It does just
what the name suggests, it puts a blank *hole* in the received signal.
The NB is better for fast rise time impulse noise such as lightning and
automotive ignition noise. NR will do nothing to help that type noise.
I do not believe there is any one magic bullet. What works for one
noise may not work for the next one.

Actually - all of the above. I have spent a lot of time playing with
all the NB and NR settings (there are many combinations) and have
incorporated the ATT and reduced RF Gain into the mix. My
understanding is bringing in the RF at a lower level allows the
various DSP devices to get a running start at cleaning up the noise.
So far I have had very little success.
I am hoping someone out there has come up with a magic bullet setting
(or even a workable setting) that can be shared. This has been a
summer with loads of lightning static.
