Henry,
Your real answer depends on your particular hearing loss, so no one else
can say what your particular "desired pitch" can be.
I suggest you experiment with different pitches in real time CW QSOs.
Tune the station to the pitch that you can copy best - then figure out
what that audio frequency is.
You can play the CW through an audio spectrum analyzer to determine the
pitch that you hear best. One such analyzer is Spectrogram, and the 2
freeware versions (5.71 and 16) can be downloaded from my website
www.w3fpr.com. Look for the links near the bottom of the opening page.
These are local copies of the Spectrogram files that have been virus
scanned numerous times. I hear reports that some sources of Spectrogram
contain bad stuff, but these are clean copies.
SpectrumLab and other audio spectrum analyzers can do the same thing.
73,
Don W3FPR
