[TowerTalk] NR-1 noise reduction unit.

[Rob Atkinson]

It's an interesting box; wish the manual included a schematic drawing.
They make sure that you realize it's only good for impulse noise, so
if that's all you ever have to deal with then okay fine.  In my
environment, I've had to deal with leaky cable noise (sounds like
white noise), and continually shifting plasma TV noise among other
nuisances, so the old phase shifting and nulling networks using a
noise pickup antenna are necessary here.  But if all I ever dealt with
were AC line noise and motor ignition noise for example, this might be
pretty good.   It might be useful for mobile operating.
