Back in the late 1980's I was working and living in the country of
Californiastan when the community I was in at the time started having
problems with their electric garage doors opening and closing as if
possessed by some evil door opener. It turned out that the US Navy
was testing the big search radars on some ships in the bay. Those big
powerful radars were producing an RF harmonic signal that was just right
to screw with the RF remote controls for a lot of openers. :-)
