I hear it on both my Drake R4 and my Omni VI+. I tried both last night to make
sure it wasn't what you suggest. It's not an
artifact of receiving, it's on the transmitted signal. To my ear it's more
noticeable when tuned in USB mode than LSB. I suspect
this is because the pitch is rapidly decreasing on USB which is more easily
heard than when it sneaks in from underneath. It truly
sounds like the same "microchirp" we've discussed at length a while back. In
LSB mode, which TT's and ICOM's use for CW reception,
it is hardly noticeable. I guess the poor Kenwood users would hear it better.
Just one more reason to trade that Kenwood in on a
better rig - hi! (I don't know which mode Yaesu typically uses for CW RX.)

Subject: Re: [TenTec] OMNI VI <bleeping> CW note
Sounds fine on my Corsair II no matter how I try to tune it to be
critical. Could it be that there's just a tiny microchirp on the edge of
the filter that when you tune to the edge of a receiving Omni VI filter
is converted to that click... Is there something about the fast AGC in
the receiving Omni VI in QSK mode that's hardening a slightly hard
leading edge? Does going to slow AGC affect the perceived signal? When I
tune my Corsair II for a very low pitch beat note any chirp should be
increased as a proportion of the frequency, but I don't hear any such
thing...
