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.
