Description

AO-27 is an amateur satellite constructed by the Amateur Radio Research and Development Corporation (AMRAD) at the facilities of Interferometrics in McLean, Virginia. It was originally designed as a commercial satellite known as EYESAT-1 but its completion was halted part way through the project. An agreement was made for AMRAD to finish the construction of the satellite and add an amateur satellite transponder. AO-27 is an “FM Repeater” in space. It essentially consists of a crystal controlled FM receiver operation at 145.850 MHz and a crystal controlled FM transmitter operating at approximately 436.795 MHz.
