In my case, I am absolutely positive. We're splitting hairs here as to
what to call the noise. It's a mechanical noise and as N4UC said, the
noise is heard on the relay break, not the make. I can prove that by
tuning the external keyer speed way down and sending a single long
dash. And it IS annoying. I've owned dozens of rigs capable of QSK and
non-QSK operation and while some of the others showed relay noise like
this in QSK mode, NONE made any noise in non-QSK mode except at the
beginning and end of a transmission. This sounds exacly like the noise
one would hear from a larger reed relay that is not mechanically
isolated from a circuit board.
As time allows, I'll dig into my Orion II and solve this.
