Wayne .. This is the only feature that I’ve found not adjusting properly to the CW PITCH setting … I think everything else works like it’s supposed to.
I just went out — doing battle with coastal gnats and other gnawing insects inhabiting my patio :-) — and tried it again. (There needs to be a bath soap with DEET in it). Narrowing the receive bandwidth has no effect on sound field centering. A CW PITCH of 700 Hz will center right between the ears when the signal is tuned. With CW PITCH at 500 Hz, it is ALWAYS off to the left and does not center at either wide or narrow bandwidths. When tuning across a signal it slides from right to left (or vice versa) as the signal’s pitch changes like you’d expect. When tuned, however, it won’t center unless CW PITCH is at 700 Hz.
