Subject: Force12 C31XR SWR Problem

You get struck by lightning, and it can bust ANYTHING it wants to. And
there may be no discernible reason why it blew one thing up and left
another unharmed.

The stories of what got blown up and what got left are stuff of
legends.

Time to get up there and measure stuff out.
