> Can you imagine what would happen to our very delicate and unshielded electronics today?

Nothing is that unshielded. Things were designed to survive lightning back then, and they are designed to survive lightning now.

The question is really how our power distribution grids will fare. And the experience with telegraph back then is very relevant.

How do you shield a radio receiver from electromagnetic disturbances on the antenna?

What frequences we're talking about?

[marcosdumay]

Mili-Hertz to micro-Hertz.

That's where almost all the energy is. AFAIK, it doesn't start to become a problem because current antenna have an incredibly low sensitivity on that range. But well, I can easily overlook some detail.

For the purposes of this discussion, lets say “the same frequencies the radio operates on”
