[Elecraft] ERR IO3 AGAIN

[John Ragle]

In my experience, a wide variety of things is possible. For example, 
last summer (2010) I lost one channel of my router (out of 4 in use) to 
a lightning strike, and my wife lost her entire computer (fried MoBo) to 
the same strike, even though she was unplugged from the mains...she was 
plugged into a CAT6 line from the router, but NOT the same channel that 
fried.

The weird (interesting?) aspect to this is that the cable TV run that 
serves us is fiber optic up to the street entrance. This implicates the 
coax line from the street entrance to the house (buried at least 1' 
underground) and the house wiring itself.

During this event, my computer was plugged into a plug strip and into 
the same router, but was turned 'off,' and a dozen or so pieces of ham 
gear were plugged into antennas and mains ('off' again), not one of 
which was damaged.

This particular strike was perhaps 150 yards away at the end of the 
street. My tower is grounded through two No. 4 cables and 8 foot ground 
rods.

As has been stressed on this list server, the effects of a near strike 
can be quite quixotic.  I once got a good jolt (actually more of a 
strong 'tingle') when leaning against the metal frame of my garage door 
and a strike occurred across the street.

Faraday's Law holds, but where? The equivalent circuits are not always 
obvious...time for more tinfoil hats...read the archives.
