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.

Hello gang,

I have an Orion currently using it with a TT Centaur. Works well full QSK.

I have an opportunity to get an Alpha 91B for a good price.

Looking at the Alpha I see it does nor suppport the full keying loop like the TT amps.
So, what do I need to do to hook the Orion to the Alpha for full QSK?
Any less function than a TT amp?


Thanks,
Lee, KC9CDT
