I think I'm the first to use and mention in this forum the CM500. I have some
age and noise related hearing loss (mostly right side) and tinnitus. I use a CW
sidetone around 400-450 HZ.
The K3 has a built-in receive equalizer so I don't see a need for an external
one.

If your hearing loss is age-related, try a lower frequency, like 400-500 Hz.
Age-related hearing loss usually is in the 1000-3000 KHz range. If it's
occupational-related, it could be any frequency.
I recall an article in QST a number of years ago by N4GG about building a
small equalizer. As I recall it was a realtively simple project and you can
individually boost various freq bands as needed.
