[Icom] Interesting

I took a hit a few years ago that from all descriptions matched yours to a
tee.  HOWEVER, although my insurance settlement was on the surface a fair
one, I found that I had electronic devices that survived the initial hit but
failed months later.  I was told by an engineer for a promient surge
protection manufacturer, that every sensitive solid state device was
stressed.  Those most sensitive, died immediately. Those less so, lived on
for short but variable lengths of time.  I say this, sir, only to warn you
that I would bet many of the devices that seem to be okay, will die early,
if not soon.  Sorry about that, maybe I will be proved wrong.
