I'm just not sure the computer works here – the energy is all wrong

I can top that one - in 1987, I was part of a team doing a physics experiment on the Greenland ice cap. We were operating round DYE 3, which at the time was still operating one of the cold war early warning radars. Our job was to measure the topography of the rock beneath the ice using a 300 MHz radar (ice is pretty much transparent at that wavelength). The early warning radar was nowhere near our frequency - but we still suffered from MASSIVE interference effects; in particular, the A-D component we were using triggered at the wrong point several times during an acquisition cycle - fortunately, always at the same point, so I could post-process the data to correct it! And there were innumerable other effects; so much so that we had to line the electronics vehicle with tinfoil to get anything going at all. And the interior of the instrument caboose got incredibly hot - you wouldn't think that getting too hot would be a problem in Greenland, but it was! We operated up to 5 km from the base, and still suffered all sorts of strange interference effects.

The early warning radar did have waveguides the size of heating ducts, and there were parts of the platform that were out of bounds while it was operating; lead underwear wouldn't have saved you!
