Numbers stations started in the cold-war era, possibly WW1 and continuing into this modern day. SWA has written other articles on these stations. Until now, there was no one-stop comprehensive, exhaustive, resource for learning about these stations. Two important questions arise about these numbers operations today: Are they just distractions with no real world function & aired only for novelty purposes to get SWL's all excited? Are they operating with a real purpose in the world for communicating with intelligence agents known as "spies", or do they operate simply to test their equipment just in case?

The Russian Woodpecker was a notorious Soviet radio signal that could be sporadically heard on the shortwave radio bands worldwide between July 1976 and December 1989. It sounded like a sharp, repetitive tapping noise, at 10 Hz, giving rise to the " Woodpecker " name.
Yosemite Sam is the nickname given by DXers to a mysterious number station that first surfaced on December 19, 2004. It transmits on several shortwave frequencies in dual side band : 3700 kHz, 4300 kHz, 6500 kHz, and 10500 kHz. The nickname is taken from the Looney Tunes character Yosemite Sam , whose voice is played as part of the unusual transmission. [ edit ] The transmission series The transmission begins on one of the frequencies. Ten seconds later, it is repeated on the next higher frequency, and so on for a total of two minutes.
As we speak, broadcast signals are moving invisibly through the air all around you, from millions of sources. And some of them are really, really freaking weird. We know this because occasionally somebody with a shortwave radio, or a special antenna or even a common household television, will capture one of these mystery signals and suddenly start broadcasting utter insanity.
