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.
