Japanese Satellites Carrying Amateur Radio Payloads are Launched into Deep Space

Japan has successfully launched its Hayabusa 2 asteroid sample-return mission into deep space, and with it, two satellites carrying Amateur Radio payloads. A Japan Aerospace Exploration Agency (JAXA) rocket lifted off on schedule early on December 3 (UTC), carrying the Hayabusa 2 spacecraft on the first leg of its journey to Asteroid 1999 JU3. Along for the ride into deep space are two Amateur Radio satellites, Shin’en 2 (Abyss 2) and ARTSAT2: DESPATCH. The launch had been postponed twice owing to unfavorable weather conditions. Shin’en 2 will identify as JG6YIG, while ARTSAT2:DESPATCH will use the call sign JQ1ZNN.

Satellites Carrying Amateur Radio Payloads Among Those Lost in Launch Explosion

The GOMX-2 and RACE CubeSats were among more than 2 dozen satellites that were lost after an unmanned Orbital Space Sciences (OSC) Antares 130 vehicle exploded spectacularly shortly after launch at 2222 UTC on Tuesday, October 28, from the Mid-Atlantic Regional Spaceport on Wallops Island on Virginia’s Eastern Shore. Both satellite packages carried payloads that operated on Amateur Radio frequencies. The Antares is a new medium-class launch vehicle developed by OSC. The rocket exploded about 6 seconds after launch, sending a huge ball of fire hurtling toward the ground, which set a massive fire at the NASA launch site.

Radio Amateurs Report Hearing 4M Moon Orbiter JT65B Signal

Radio Amateurs Report Hearing 4M Moon Orbiter JT65B Signal

[UPDATED 2014-10-24 1942 UTC] A Chinese Long March 3C/G2 rocket carried the Manfred Memorial Moon Mission (4M) lunar flyby experiment into space at 1759 UTC on October 23, on its way to a lunar transfer orbit and a return to Earth in about 9 days. Radio amateurs in Oceania and Europe have reported hearing the JT65B from the onboard Amateur Radio payload. Lunar flyby is to occur, nominally, on October 28, and the Amateur Radio package will transmit continuously throughout the voyage. During the lunar flyby, the spacecraft will be about nearly 248,000 miles from Earth and between 7440 and 14,480 miles from the Moon. The 4M Amateur Radio payload is transmitting a WSJT JT65B beacon and telemetry on 145.980 MHz. Roland Zurmely, PY4ZBZ, in Brazil, was reported to be the first to receive telemetry from the JT65B beacon at 1918 UTC.

LX0OHB-4M Amateur Radio Payload Ready for Launch
October 15, 2014

The integration of the LX0OHB-4M amateur radio payload was completed on Sunday night, October 12 and is now ready to launch.

The onboard clock has been adjusted to start JT65B (145.980 MHz) at the UTC minute +/-1 second. It is likely to drift during the mission, and manual offset introduction will be required after a week or so. The launch date is October 23 at 1800 UTC.

Beginning of transmission of 4M will start between 1917 UTC and 1927 UTC. Refer to the provided maps and animations links in the blog section (see also older messages) to determine your visibility. Alternatively, use the ‘tracking’ section where you can compute your tracking elements by introducing your geographic coordinates. The table can be copied/pasted into a text file. As the apparent movement will be close (and closer) to the one one of the Moon, manual pointing is easy but for the largest arrays. We’ll try to publish equivalent TLE’s to input in usual tracking software.

A spectacular rocket launch from Virginia’s eastern shore late Tuesday (Nov. 19) lit up the night sky like an artificial sun, kicking off a record-breaking mission to put 29 satellites into orbit.

The Orbital Sciences-built Minotaur 1 rocket launched into space at 8:15 p.m. EST (0115 GMT Wednesday) from NASA’s Wallops Flight Facility in Virginia to begin the ORS-3 mission, which is run by the U.S. military’s Operationally Responsive Space Office. The launch was expected to be visible to millions of observes along the U.S. East Coast, weather permitting.

Amateur Radio Satellites Ready to Fly on Dnepr Launch Nov 21

A Russian Dnepr rocket is set to launch on November 21 at 07:10:11 UTC from Dombarovsky near Yasny. This launch is expected to deploy 32 satellites, many of which are amateur radio or experimental using amateur radio frequencies.

Nader, ST2NH has developed graphics depicting the known satellites on the launch, as well as published frequencies of those using amateur radio. Nader’s blog can be found at

A full list of known payloads can be found at

Several of these satellites are expected to provide opportunities for two-way amateur communications via linear transponders, FM to DSB repeaters, or digital links.

FUNcube-1 from AMSAT-UK and AMSAT-NL is a 1U cubesat that includes an educational beacon and 20 kHz wide linear transponder. Detailed info is at: and


Delfi-n3Xt is a 3U cubesat from Delft University of Technology that includes a 40kHz wide linear transponder and high speed S-band downlink. Detailed info may be found at
Triton-1 is a 3U cubesat from ISIS-BV (Innovative Solutions In Space BV) with a AIS (ship location service) radio science experiment. After the experiment is complete (est. 3 months), the spacecraft radios will be reconfigured to U/V FM to DSB (“AO-16 mode”) repeaters open for amateur use. More info is at and


CubeBug-2 is a 2U cubesat from the Argentinian Ministry of Science, Technology and Productive Innovation, INVAPS.E., Satellogic S.A., and Radio Club Bariloche. It is a technology demonstration mission, with digipeater and data downloads open after initial experiments. See and

FITSAT-1 satellite scheduled to write Morse code in the sky

If successful, FITSAT-1’s Morse code messages will be visible to the naked eye

We like to think of space as the one place where all tech is high and all gadgets are bleeding edge. That may be the case most of the time, but Japan’s Fukuoka Institute of Technology is taking one small step backward for man by sending a satellite into orbit that uses Morse code and bursts of light to send messages back to base. FITSAT-1, which will be launched from the International Space Station (ISS) in September 2012, will use LEDs to flash Morse code messages like an outer-space Aldis lamp that may be bright enough to see by the public with the naked eye.

ARISSat-1 to Help Celebrate Gagarin Flight Anniversary

ARISSat-1 transmissions from the ISS will be used to help celebrate man’s 50th year in space. Yuri Gagarin became the first man in space on 12 April 1961. Fifty years later on 12 April 2011 the Russians will have a nationwide commemoration of this historic event. The ARISSat-1/RadioSkaf-V satellite on board the ISS and awaiting deployment in late July of 2011 will be turned on and transmit during the celebration period. The transmissions will begin on Monday 11 April 2011 at 14:30 UTC and continue until 10:30 UTC on 13 April 2011.

NASA Calls for Amateurs to Listen for Satellite
January 19, 2011


HUNTSVILLE, Ala. — Wednesday, Jan. 19 at 11:30 a.m. EST, engineers at Marshall Space Flight Center in Huntsville, Ala., confirmed that the NanoSail-D nanosatellite ejected from Fast Affordable Scientific and Technology Satellite, FASTSAT. The ejection event occurred spontaneously and was identified this morning when engineers at the center analyzed onboard FASTSAT telemetry. The ejection of NanoSail-D also has been confirmed by ground-based satellite tracking assets.

UO-11 Report – December 5, 2010

This report covers the period from 29 October to 30 November 2010. During this time the satellite has been heard from 30 October to 09 November and 19 to 29 November . At the time of writing it is is expected to switch-on 10 December.

Excellent signals have been reported from stations located around the world, and good copy obtained from decoded telemetry frames.

The satellite is now transmitting during eclipses, although signals are weaker at those times. This indicates that there is still some capacity remaining in the battery.
