Just a minor quibble: with the Orion set up for normal operating, with
8msec risetime (as discussed ad nauseum in the past) and 50% weighting
on the transmitted cw - I'm skeptical about true unmuting of the main
receiver between dit characters at an actual 30wpm.

Well Barry, I don't know what to say... You are one of the posters I normally
give credence... It must be my lieing ears then, because I DO hear what is
going on the frequency during transmit - even with the Titan in line...
Now whether the receiver(s) are completely unmuted I cannot say, but I can
hear other stations transmit while I am... I can hear the DX go CQ back in my
face, etc... 30wpm may be an exaggeration - I normally have the Orion showing
26-28 on the screen when working during good contest conditions... I usually
use 18-20 on 160 for non-contesting given the conditions there... 30-32 is
mainly used near the end of a 48 hour grind where everyone is up to speed after
2 days of code practice and all I am doing is short, snappy, CQs...
So how do we go about testing this?
I've done extensive testing in the past as well, as part of the beta
testing. I tuned to a 40M SW carrier and transmitted (low power)
while recording rx audio with my soundcard and software that could
display waveforms. I knew for sure when rx audio was present and when
it wasn't.
Before we go any further, are you sure you don't mean you're hearing
callers between characters as opposed to between actual dits?
