An EMP has nothing over close proximity lightning, and/or ESD - The physics of which have changed little over the past 50 years.

Again BS. And EMP is a cascading even in the atmosphere. It does not act like a nearby lightning strike.

"Again BS. And EMP is a cascading even in the atmosphere. It does not act like a nearby lightning strike."

No, not really. The failure mode of the electronics is exactly the same, whether it is caused by lightning or an EMP. Excessive induced voltage across a semiconductor junction.

So what happens to the electronics connected to a radiotelescope when it gets struck by lightning? Does research stop while equipment gets replaced every time?
