[Elecraft] KPA-1500 failing on 160...AGAIN!

[Peter Dougherty]

My KPA is once again repeatedly failing on 160m. I haven't used it on
Topband since about the end of March, when it was fine. My antenna is
checking out fine on my AA-230 ZOOM analyzer, and I can run 100W into the
antenna from the K3s with no problem.


I'm getting FAULT: PWR REFL on every keydown with drive power at any level,
even just 5W in will cause it to fail.

I am running from the K3s directly into the KPA-1500, and from the KPA to an
antenna switch out to the antennas. Everything was 100% last time I fired
up, and the am IS working on 20 and 40 (the only other bands I've used since
March). Any idea where to start looking here? I'm at a complete loss and
have just missed two new DXCC entities on 160 as a result.
