Interesting; thanks for sharing the site. It shows that I have a peak at 500 Hz, which correlates pretty well with my preferring a CW pitch of about 550. The site has, however, two recognized sources of error. One is that it can¹t correct for peculiarities in the response curve of the headset used. The other is that the pitch change itself creates a subjective sense of impact. It showed that I have a second peak at around 3 Khz, which seems physiologically unlikely. Tones that high I find annoying, like chalk screeching on a blackboard, which may be the subjective equivalent of loud.
The other side of the QSO equation is what tone frequency will best get you through the QRM. I wonder where most people who are listening to me (and a pileup of others) have their filters peaking? By listening to whom and where the DX is working as the pileup goes on we can infer the operator¹s tuning habits and be on the next expected spot, but not all of them behave in discernible ways. If the target station seems to be listening at the same spot through multiple QSOs (as in contests), is it better to split (or XIT) and transmit up a touch first, or down, and by how much? Anyone know where the CW response peak of the ham population (or of its receivers) lies?
