[Elecraft] Controlled Envelope SSB

[Bob Novas]

I downloaded the 11x14_Hershberger zip archive and ran the cessb.m script
through a fresh install of Octave 4.0.0 on a Windows box.

- I had to install the signal package  (pkg install -forge signal)
- I have to load the signal package every time I start Octave (pkg load
signal)
- I had to comment out all lines starting with saveas - there appears to be
a bug in Octave that causes it to hang when saving plots. ("OpenGL feedback
buffer overflow). you can also just abort the gs.exe process to allow the
script to continue.  I tried adding 'graphics_toolkit("gnuplot");' as the
first line of the script, this was said to be helpful in some of the bug
reports, but didn't help me.
- if you step through the code you can see the plots, if you run the code,
you won't see the plots.

Interesting.  I can't actually hear much difference when I play the original
and processed wav files, but the script reports a power gain of 3.6db which
would be significant.

I'd love to try this out on the air!

Bob, W3DK
