Regarding the communications she is explaining, here is a video that discusses time, GPS and satellites:

When I was going for my FCC radio license, we learned about crystal recievers which were replaced by vacuum tubes. It was a brief history part of the course, before we went into the digital part.

It was suggested that moths got into the old vacuum tube radio sets. I do know from experiene that bugs love the heat older electronics generated.

I had an old style cabinet radio and 78 RPM phonograph player (to play those old slate records) given to me by my father. It had tubes and the dial was backlit, perfect for summer nights as teen in my bedroom. It looked very much like this picture:



It was built in the thirties with a square antenna enclosed within it. I had to reach behind it to turn it for reception and was able to listen to programs from Europe and Latin America late at night in the sixties.

But the operation of the original crystal sets always fascinated me. I don't know if there are really any of them around or if they'd be able to pick up anything with the changes in transmitters. Later I had one of the wooden box style radio inwhich I could see the crystals, and they were not artificial ones.

Anyway, your description reminded me of all of that. Although I hadn't thought about it in years and my memory may be off a bit. No one seems to know about this anymore.
