It would be good to get to the bottom of
what brings on the perfect storm while Hans testing didn't highlight anything.
Alan,

I don't know how Hans had no trouble although it could be that most QCX do survive abuse. Maybe only a few actually have problems?
The design here http://www.norcalqrp.org/files/NC2030/NC2030_v5.pdf was mentioned by someone, it shows how to protect 3 little BS170s from some class E hazards. Difficult to spot the actual PA components!
