A YouTube video I recently linked here demonstrated how to use my
NoiseNuller application to pull a SSB signal out of local noise using
enhanced diversity reception. Somebody who watched it asked how well it
would work for CW signals, so I created this quick (5 minutes) video
demonstration to answer his question.

Since CW signals are essentially single tones (theoretically, anyway)
they are easier for the FFT processing to keep them separate from the
noise (only one bin to phase shift), so the resulting improvement in SNR
is actually better than for a voice signal.
