Yes, I did understand that Andy. My GUESS was that the PA-DSS (efficiency) is sensitive to the actual load impedance. I suspect that the SWR fault, that I sometimes see, is also sensitive to low vs high impedance.

I have seen several FAULT 09 REFL HI events and they were all caused by an operator antenna switching error. PA DISS (FAULT 11) is not an SWR fault although it appears it can be induced by a load mismatch. 73, Andy k3wyc From: Michael Blake <[email protected]> Sent: Monday, May 28, 2018 6:10 AM To: ANDY DURBIN Cc: [email protected] Subject: Re: [Elecraft] PA DISS fault and relationship to SWR Andy, I have seen this too. My remote tuner will sometimes quit with SWR in the 1.4 : 1 range. Sometimes it causes a KPA500 SWR Fault and sometimes not. My GUESS is that it depends on whether the impedance is <50 ohms or >50 ohms. The SWR does not tell you which.
