Just in case anyone thought I was kidding about the "Blue Cube" at Moffett Field in the SF bay area burning out a slew of garage door openers in the '80s, only to be found out when one of the Cube's engineers got home from work one day to find that his, and his neighbor's garage doors no longer worked.

Do you live on or near a US military base? Do you have trouble with your automatic garage door opener? Is your neighbour muttering darkly about "the government"? Well, he may be right. The US military is the authorized user of the 380-399.9 MHz spectrum, and military radio systems like the new Land Mobile Radio system can easily drown out the weak signals of your garage door opener on similar wavelengths. MSNBC reports (link).

As a public service, we'll add that recent MIT experiments with tinfoil hats(link) have also noted critical vulnerabilities to common military spectrum wavelengths. Then again, they would say that, wouldn't they?
