[Elecraft] K4 Remote: My QTH vs. a friend's, many miles to the north

[Dave (NK7Z)]

Hi Jorge,

That device would not stand a strike...  As per the US Weather service, 
(https://www.weather.gov/safety/lightning-power), a typical lightening 
bolt runs around 300,000,000 volts, at 30,000 amps.  That device is 
speced for 4000 volts...

For Elecraft to protect the amp against a lightening strike as you 
described you had, they would need to add a LOT more hardware than that 
to the price of an already expensive amp, and most people would never 
see need the protection.  Hence why they don't even try and protect 
against a direct lightening strike.

The onus for lightening protection always rests with the device owner.

73, and thanks,
Dave (NK7Z)
