[TenTec] Help please , Orion with Alpha 91B

[Bob Henderson]

I'm flumoxed by your comment on the 87A.  The 87A is as fast a QSK amp 
as I've ever seen.  It's awful with Ten Tec loop keying, because it 
switches too fast for it.  My 87A with my Orion is good to better than 
100wpm, not that I send that fast.  When loop keyed it clips the 
tail-end of character elements and is awful even at 18wpm.  Doesn't the 
Titan still use a vacuum relay, which is why it needs loop keying in the 
first place.

>Hi Lee; I suspect it will depends bit on just how fast you operate. If the 91's keying is as fast as the 87A you won't have much if any degredation in the QSK. Of course, I could tell the difference when I sent an exchange to  some of the 40+ DX stations, but for normal keying up to 30 WPM the 87A is as good as the Titan that lives on the shelf below it.
