[Elecraft] [K3] CW Sidetone Pitch Change Problem

[Bob McGraw - K4TAX]

More likely the low level distortion created in the analog audio path 
typically occurring with the stronger signals.  That distortion is therefore 
multiples of the fundamental and the human hearing will allow the higher 
frequency components to be dominate, often described as masking effect thus 
perceived to be louder.  It is the combination of F + Fx2 + Fx3 and etc. 
This is usually the result of the dither component of digitally processed 
signals.  A 2nd point with stronger signals the background noise, always 
higher in frequency content, will be suppressed thus the timbre of the 
signal will change as the reference point of hearing changes.

A very common psychoacoustic condition with two legged folks referred to as 
human.
