Bill,
When you say it's keyed at 30 WPM, do you mean you're keying the amp
(QSK) and allowing it to key the transmitter - or the other way around?
It should work fine in either direction if the transceiver is properly
sequenced. But if the RF gets applied a bit too soon it can fault the
amp. I've had this happen while driving my 89 with a Collins
transmitter, in which the amp-keying relay is cascaded after the main
keying relay. So even with slow PTT it faults. I had the same symptom
- no red indicator lights after fault. There are multiple ways to fix
this kind of thing by getting the keying sequence right.
On the other hand, the fact that you tried 3 different transceivers
makes me wonder about the timing being the real cause of your problem.

Chris, W2PA
