I've done some measurements that may help - http://blog.aa6e.net/2006/07/tt-orion-adventures-in-time-domain.html

Depends on what you really mean by "QSK".

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? denny / k8do
