[Elecraft] [QRO] KPA500 PIN diodes / High SWR

Back in Feb, Guy (K2AV) wondered in another thread:
------------------
I still wonder what happens to the KPA500 pin diodes when you open with a
dit into an unterminated coax and a 20:1 SWR.  Wayne and Co are working
their magic into a problem that has taken most amps down. 
------------------

I would also like to know if they have been able to provide sufficient
protection, magical though it would be.  That would be a terrific selling
point.  I know I will eventually hit the key while in a confused state with
the KPA500.
