[Elecraft] K3 shuts OFF over 95w...

[Paul]

Mike,
I had this exact same problem during CQWW. It turned out to be RF getting into the K3 thru the contest keyer leads, which I had never hooked up before. Wrapping all the leads with RF chokes/toroids fixed the problem...check to see that you have not added something new recently. I also assume that if you have a beverage connected to the Aux Ant, that you also have an RF limiter in that line, as that can raise havoc with the K3 as power is increased--especially true when you add in a linear amplifier.
