Sorry your email address dosn't work but thanks for clarifing the
hookup i must have missread the original statement you made whereby i
thought you said the pro was completely disco i totally understand if
it had anything connected that explains it!!

however you confused me more so, now that you said the pro getting fried
somehow 'saved' your other gear from being damaged... i can't see how
that happened unless you feel the rig it self actually absorbed ALL the
energy i presume the odds of that are slim

so can you help unconfuse me??

and it was great to read about how the mil does stuff pretty cool

again sorry about your damage hope you had arrl rig insurrance

Hi

Dear Amos

i saw your post and hope you wouldn't mind if i asked you a quick
quesiton


Your Icom that was damaged, was unplugged from everything so how did
lightning 'get to it'??

I was kinda distrubed trying to figure it out
\

Ground Loop. Took time to find it though.

The Astron RS-35 power supply connects utility power neutral to the
case. It also connects the 13.8 volt return to the case. [This is
commercial common practice but is prohibited in Military Systems
design.] Although everything on the operating table was isolated from
the utility power and external antennas, everything was connected
together by coax braid, connections to the operating position common
'ground', and the 13.8 volt return.

Remember, this strike caused large area damage. Close to 50 homes
suffered some damage. Several homes took up to 6 weeks to have their
internet functioning again.

The lightning strike tripped all [ALL] ground fault interruptors in the
house. The ground loop in my system connected chassis and power returns
and coax cable together. The weak link were circuit boards in my 756 Pro
II filter and tuner. The boards VAPORIZED. Smoke all over the place.
Pungent smell, etc. That failure protected my IC-746, Kenwood TM-G707,
etc from damage. [Expensive fuse!!]

I wonder if it also protected my swimming pool pump and heater from
damage grin?
