[Elecraft] Anyone use a noise canceller?

[Ron D'Eau Claire]

Those interested in noise canceling might be interested in what the rest of
the communications industry is doing with exotic integrated circuit systems
that kill noise by inverting and adding it to the signal at the antenna
input.

There's one completely IC-based system that's now available:

The good news is that it is on one chip and reportedly quite effective.

The bad news for the casual homebrewer is that the chip measures less than
1mm (<0.04") on a side.
