HORYU-2 Commencing AX.25 FSK Operation

On May 22 the amateur radio satellite HORYU-2 carried out tests using the 1200 bps AX.25 FSK downlink on 437.375 MHz.

It is understood that signals were received by JA1GDE, JA5BLZ, JA6PL and JA2MJA.

On May 23 Mineo Wakita JE9PEL decoded the AX.25 telemetry data and made available this recording:

The AX.25 transmissions are being made when HORYU-2 is within range of Japan. In the rest of the world it is transmitting a CW beacon on 437.375 MHz as shown in this video by Luciano PY5LF.

Listen to HORYU-2 on the Web

Andrei YO8SSQ and Cezar YO8TLC have made available a web based receiver to enable listeners to hear the new amateur radio satellite HORYU-2 when it’s within range of Romania.

The WebSDR receiver is located at the Astronomical Observatory Department of “Stefan cel Mare” University in Suceava, Romania, latitude 47.6417N longitude 26.2453E, grid locator KN37cp. The height ASL is 350m.

The hardware consists of two SDR receivers which are fed into 48 kHz sound cards on an AMD Sempron 2600+ computer running Vector Linux.

The web page displays a track showing the current position of HORYU-2 and also provides coverage of the 3.5 MHz (80m) band.

Joe Acaba KE5DAR

NASA Flight Engineer Joe Acaba, KE5DAR, and his two Russian crewmates, Soyuz Commander Gennady Padalka, RN3DT, and Flight Engineer Sergei Revin, RN3BS, arrived on the International Space Station (ISS) this week.

They joined the three other radio amateurs on the ISS – Expedition 31 Commander Oleg Kononenko, RN3DX, of the Russian Federal Space Agency, Flight Engineer Don Pettit, KD5MDT, of NASA and Flight Engineer Andrei Kuipers, PI9ISS, of the European Space Agency.

A status report video released by NASA for May 14-18 notes that Joe Acaba, KE5DAR, powered on the ham radio in the ESA Columbus module. The ham radio reference occurs 09:05 into the video.

HORYU-II heard over Africa

The HORYU-2 Team

Nader Omer ST2NH, in grid square KK65gp, has made available a video of HORYU-2 recorded at 2:25 AM Friday Sudan time. The signal received on 437.375 MHz (+/- Doppler shift) was very strong.

In this video the beacon is sending CW and Nader is using manual tracking and manual Doppler correction.

Nader says: Congratulations to the HORYU-2 team

HORYU-2 Telemetry Competition

The amateur radio satellite HORYU-2 was successfully launched on Thursday, May 17 at 1639 UT and its signals have been received by radio amateurs around the world.

Built by students at the Kyushu Institute of Technology (KIT) HORYU-2 is 350 * 310 * 315 mm and has a mass is 7.1 kg. It was launched into a Sun-Synchronous 680 km orbit with an inclination of 98.2°. The TLE’s for tracking are available at http://kitsat.ele.kyutech.ac.jp/Documents/ground_station/TLE.txt

The satellite’s callsign is JG6YBW and radio amateurs are asked to listen for the 437.375 MHz  (+/- 9 kHz Doppler shift) telemetry downlink that will be using 20 wpm Morse Code or 1200 bps AX.25 FSK packet radio.

There will be a monthly competition for those who send data received from the telemetry to the KIT server, via the HORYU-2 telemetry analysis software.

The free HORYU-2 telemetry software and details of the competition can be downloaded from
