While times and technology have changed in the last 37 years, a little paper I
wrote back then might be of interest. Sorry there is something missing near the
end. Publisher's fault, not mine.

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.
