I'm probably a bit psycho at times and studied acoustics in college over
50 years ago. Now I need to figure out how to combine the two.

This probably is related to the commercial CW operators trick of laying
the phones down on the desk to copy a weak ship station through noise.
It really does work. Unfortunately, today's over-the-ear headph

Could be worse, but not much :)

I generally use 440 Hz for sidetone/pitch, thinking that it is a
familiar standard musical note and perhaps is more recognizable to the
brain in some way. I don't know if that has any validity or not...
One thing I would dearly like to have is the ability to listen to the
actual signal as I
Hi Wayne,
thanks for nice example. Definitely agree.
I am using the pitch set to 360Hz for long time and it is the best result
for myself... after long time testing and experimenting with my K3.

Two possible reasons.
