[Elecraft] NoiseNuller and Morse Code Signals

[David Gilbert]

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.
