[Elecraft] Copying CW and Pitch

Sun Mar 14 06:37:50 EDT 2021

FWIW At my age hearing of both ears starts to roll off in the 4khz range. I can remember when the upper limit was 20+khz. I'm a bass player so my hearing is quite acute at low frequencies. However for CW I prefer to copy at about 625hz. This is with filters set in the 50-500hz range. If I try to copy at a lower frequency the signal tends to get shrouded by noise. I have not specifically tested the ability to discriminate close signals though.

One of the most common forms of hearing loss starts at the high frequencies and works its way down with age, but that's far from universal. When one or more notches develop at certain frequencies, it's often the result of noise exposure at work.
