Beskrivning : Comstar 2 was launched 22 July 1976, and provided 17 years of service from 76.6 degrees W longitude. Earth stations transmit the telephone calls to the satellite on frequencies within the 6 GHz band and receive signals from the satellite in the 4 GHz band. The frequencies are altered within the satellite to prevent interference with each other.
