Yosemite Sam
Yosemite Sam is the nickname given by DXers to a possible numbers station that first surfaced on December 19, 2004. It transmitted on several shortwave frequencies in dual side band: 3700 kHz, 4300 kHz, 6500 kHz, and 10500 kHz. The nickname is taken from the Warner Bros. cartoon character Yosemite Sam, whose voice is played as part of the unusual transmission.
