Interstellar radio messages sent to nearby stars in 1999 and 2003
RT-70 in Yevpatoria
Cosmic Call was the name of two sets of interstellar radio messages that were sent from RT-70 in Yevpatoria, Ukraine in 1999 (Cosmic Call 1) and 2003 (Cosmic Call 2) to various nearby stars. The messages were designed with noise-resistant format and characters.[1][2]
The project was funded by Team Encounter,[3] a Texas-based startup, which went out of business in 2004.[4]
Both transmissions were at ~150 kW, 5.01 GHz (FSK +/-24 kHz).[5]
