[Elecraft] OT: Anyone use a noise canceller?

[Edward Dickinson, III]

Hi Mark.

The noise canceling units use phase inversion to cancel noise.  They work
okay on noise coming from a singe point source.  However, they don't seem to
work well on noise generated from multiple sources or a spread out source as
noise will then arrive in different phases.

DX Engineering's '2 Channel' feature might allow canceling from a second
source, but that's a bit beyond my understanding. 

If it is possible to determine the type of noise you are receiving, you may
save yourself some money.  Some investigation with some noise detecting
equipment (if you don't have to pay for the equipment) may be fruitful.
