AMSAT DESIGNATES SO-125 with SDR FM, DIGITAL REPEATER PAYLOAD

AMSAT has given the designation of SO-125 to the HADES-ICM satellite that was launched on March 14th from California. The satellite, from AMSAT-EA, is SDR-based and supports FM Phone and FSK digital data through its repeater. The SDR-based platform is especially significant because it can transmit as much as 25 watts when the battery allows, giving access to stations who are using handheld antennas.The coordinated uplink frequency is 145.875 MHz, and the downlink is 436.666 MHz. The repeater operates with an open squelch and does not require a sub-tone.
