[Elecraft] Speech processing

[VR2BrettGraham]

There were a number of external RF speech processor products
available in the early 80s.  I can't find the schematic for my Kenpro
KP-601, but popping the cover I see something potentially
home-brewable (all this discussion drove me to find it, as after
changing compression ratios of the KSB2's compressor, it still
doesn't sound like I would like it to).

This one could turn a RF processor-less rig into something
that sounds like a TS-830S with a D-104 - clean, punchy
audio - and change the peak-to-average ratio enough that
I once baked the paint off the cabinet of an amplifier.

Not recommended for audiophiles or those who are interested
in more casual operation.
