On December 22 members of AMSAT-DL succeeded in receiving 18 images from the 5840 MHz high-speed downlink of the amateur radio satellite FITSat-1.

In total 22 images were transmitted in the test and 18 were received at the amateur radio facility at Bochum.

The FITSAT-1 CubeSat was developed by students at the Fukuoka Institute of Technology (FIT) in Japan. As well as the high-speed data downlink on 5840.0 MHz the satellite carries several amateur radio payloads: a CW beacon on 437.250 MHz, a telemetry beacon on 437.445 MHz and an optical Morse code LED experiment.

FITSAT-1, also known as NIWAKA, was one of five CubeSats launched to the International Space Station (ISS) on July 21. They were integrated with the J-SSOD small satellite deployer on the the Japanese Experiment Module Kibo and deployed by the Kibo robotic arm on October 4.

The 5840.0 MHz transmitter on FITSAT-1 runs about 2 watts output. It supports a data rate of 115.2 kbps and can send a JPEG 640×480 VGA picture in just 6 sec.

The images received at Bochum can be seen on the AMSAT Deutschland Facebook page

They are also on the site of Mineo Wakita JE9PEL
