Hi Mike,

Is the warrantee void within 100 yards of a 50KW AM antenna? Or
howabout those half megawatt LF stations that litter the continent?

It's all about RF actually within the vehicle. The bodywork acts like a
Faraday cage against external influences. But I suspect you know that
already :-)

A couple of years back a lightning bolt hit a field I was driving past
during a storm. The dash completely blanked for 2 seconds and then came
back
to life - no other ill effects noted - just as well because the road was
nearly completely under water at that point.

The radio key remote locking can fail if you park too close to a mobile
phone mast, or someone is transmitting on 70 cms nearby, but that's about
it.

As I only operate QRP I hadn't given the matter much thought until I
checked
in the vehicle manual and saw a footnote.

I had a similar experience with lightning. The lightning hit a tall comm
tower on the side of the road, jumped out the side of the tower, hit the
roof of the truck I was in, and then struck a pine tree on the other side of
the road. The engine diesd and I coasted to the side of the road. After a
few minutes of getting my composurer back together and surveying the damage
I was able to start the truck like nothing had happened. I was expecting all
the electronics to be fried.
