[Elecraft] CW listening pitch

[Ted Edwards W3TB]

Just some fun on this...
About 40 years ago, I used to teach Special Ed Electrical Shop to
deaf/multiple-handicapped teens.  Some had very profound hearing loss.
One day I was playing with a keying practice oscillator, and one girl
started to screech.  We figured out that she had hearing at 3000-3300 Hz
and not much else.  SO, I taught her to copy CW at that frequency; she got
a novice, and we just had to handle the very high offset using separate
transmitter and receiver.  It opened a whole new world of communication for
her!  And these years later, I have no idea where she is.

Thanks for all that good  help with the pitch tone, everyone.  and 73.

"Do today what others won't,
so you can do tomorrow what others can't."
