In December 2004, a mysterious transmission was heard in New Mexico. The origin and intent of this transmission have never been determined. For more info on this phenomemon, check out this How Stuff Works article.
Recently, a similar signal has been heard in the Calgary area, and I have managed to capture the recording - have a listen:
Yosemite Sam Transmission
Rumours persist that there is more to this signal than meets the ear, perhaps you can find the secret message.
