Hi Do you have a reference for 100' distant strikes routinely destroying receivers?

A strike within maybe 100 feet is enough. There is a _huge_ EMP field around the strike. The field will induce large currents in any nearby conductors. Even if the strike is to bare Earth many feet from the antenna the potential of the earth is raised by say 1,000 volts so now anything connected between ground the power has 1KV across it.
