User:Sean 0000001/Backwards Music Station

The Backwards Music Station (also known as "Whalesong") is a Numbers Station that plays a loud, grating sound and several high pitch whines in the background. Occasionally, what appears to be a voice can be heard in the background. The Backwards Music Station was found on various frequencies on the short wave band until about 2004 with the transmissions apparently coming from both the United States and in England. There are debates whether the station is some complex form of communication known as LINCOMPEX or whether it's simply feedback from Naval transmitters.

Possible explanations for the existence of the Station
It has been suggested that the station is used to communicate with spies. The frequencies used are very similar to the frequencies used by the US Navy, and they appear to emanate from bases in Jacksonville, Florida and Virginia Beach.

There is also a source of these waves in England, suggesting that perhaps the signals are used by NATO to communicate with one another.
