Another Yosemite Sam

Somewhere in the New Mexico desert, possibly on the Laguna Indian Reservation outside of Albuquerque, there is a radio transmitter first noticed in 2004, that occasionally sends a mysterious burst of transmissions. These transmissions, called the Yosemite Sam transmission do not appear to make sense.

Spynumbers has a great post  that says beginning in December 2004, the FCC began getting reports of the Yosemite Sam transmission, which begins as an 800 millisecond data burst, similar to the sound a Blu-Ray player might make when it makes some horrible error. That is immediately followed by a clip of an arch nemesis of Bugs Bunny’s, Yosemite Sam, announcing, “Varmint, I’m gonna blow you to smithereens!”

Radio geeks/conspiracy trackers/curious people pinned down the phrase from the 1949 Bugs Bunny cartoon, “Bunker Hill.” Why it is attached to a burst of compressed information, often used by intelligence community is mysterious. That it is transmitted in on four frequencies - 3700, 4300, 6500, and 10,500 kHz - for a full two minutes without any missed time mark tends to make it even more mysterious.

These are the numbers stations - radio stations on shortwave that broadcast some sort of repetitive noise followed by strings of numbers. Amateur tech geeks first identified the stations after World War II. No one is sure what their purpose is.
