I'd think that maybe the RIT or maybe the XIT is on and they don't know it.
Also many of todays rigs use different offsets for CW.  There is no
standard.  The old Collins frequency was 1500 Hz as I recall.  That's way
out of your passband.  I've seen folks tune in a station such that it
produces a 400 Hz note.  They weren't aware that their transmitter was 300
or 400 Hz away.

As to hearing loss with us older folks, yes it does start with higher
frequencies but these are way way above the typical CW note at 800 Hz or so.
If a person is having trouble hearing a 800 Hz note then they most likely
couldn't hear two trains run together.......standing between them.  Now
musically, maybe they can't distinguish between 800 Hz and 900 Hz or 700 Hz
but most folks, even with untrained ears can easily hear the difference.  I
think most is careless operators or one more step toward operators that just
don't care.  Seem to me that it's quanity vs quality in many of todays
operators.
