[Elecraft] Copying CW and Pitch

[Fred Jensen]

As a result of "adventures" in my 20's, the entire audio spectrum is a 
"notch" with a peak around 590-600 Hz [see K9YC's last sentence].  
That's where I put my sidetone/pitch.  Around 1990 or so, I built a 
little plywood cube with a Mother Bell insert from a standard black 
telephone in it. I filled the box with cotton balls and put it on the 
side of the rig, pointing up.  Over-the-ear headphones had become 
ubiquitous and the old "cans" were no longer available so the 
"headphones on the desk" trick didn't work well.  It was surprising what 
I could copy with the little speaker that was mush with the phones on.
