 Noise reduction is also available in CW mode.  The LMS algorithm converges on
a sinisoidal wave and forms a filter around the signal.  CW or WSPR is pure
sinisoidal and the NR works the best with these two modes.  Last night, I
was getting QRN and the NR/NB made it more plesent to the ear.  In spite of
that, when I turned off NR/NB, WSPR dB levels were about the same.
