    DSLWP Lunar satellites will transmit WSJT JT4G mode

    Two microsatellites DSLWP-A1 and DSLWP-A2 carrying amateur radio payloads are planned to launch with the Chang’e 4 Relay satellite on a CZ-4C from the Xichang Space Center into lunar orbit in June 2018

    Developed by students at the Harbin Institute of Technology the amateur radio payload onboard DSLWP-A1 will provide telecommand uplink and telemetry / digital image downlink. An open telecommand is also designed to allow amateurs to send commands to take and download an image.

    The satellites are 50x50x40 cm with a mass of about 45 kg and are 3-axis stabilized. Two linear polarization antennas are mounted along and normal to the flight direction.

    The downlinks for DSLWP-A1 are 435.425 MHz and 436.425 MHz while downlinks for DSLWP-A2 are 435.400 MHz and 436.400 MHz using 10K0F1DCN or 10K0F1DEN. Will use 250/500 bps GMSK with turbo code or JT4G.

    Planning a launch into a 200 x 9000 km lunar orbit.
