[Elecraft] [K3] Subtle Change in CW monitor tone

[Greg Buhyoff]

Ditto, I have had as well on two K3s (2230 and 2499) --- on strong CW
signals.  Thought it was some sort of long/short path phenomenon.  But, I
wondered since it occurred on some signals that I just could not figure for
that phenomenon given the short skip on a particular band that was occurring
at the time.  Not really that bothersome, just odd.  My AGC is set to fast
and the 400 Hz filter engaged.
