These days my ear is perfectly tuned to 1000-Hz. I can whistle it
within a few Hz. 45 years of working on radios with 1000-Hz tone modulation.

I usually tune CW pitch somewhere near 550 to 700 Hz for weak-signal
copying (SNR=0).

Yes. I believe that's the "universal orchestral tuning pitch."
My XYL and I have a running joke. When we go to anything musical, and the
orchestra commences tuning, I ask "What's that?" She says "A" and
we're ready to
enjoy another performance.
