Thanks for the reply.  Please note that I have no issue with high SWR faults.  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.

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.
