The following satellite has been added to this week's AMSAT-NA TLE Distribution: SONATE-2 - NORAD Cat ID 59112 Downlinks on 437.025 MHz, 145.825 MHz, 145.840 MHz and 145.880 MHz have been coordinated by the IARU. Thanks to Nico Janssen, PA0DLO, for the identification. The following satellite has been removed from this week's AMSAT-NA TLE distribution: BeliefSat-0 NORAD Cat ID 58695 End of mission. This mission was interesting as BeliefSat-0 is not a free flying satellite. Instead it is a "hosted payload&q ...Continue Reading
