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.
