Built by university students and research organisations from 23 countries around the world, the QB50 constellation aims to study the lower thermosphere 200-380 km above the Earth.

11 QB50 CubeSats were deployed in the first phase and a further 17 will be deployed in the second phase. The beacons should be activated about 30 minutes after deployment.

The QB50 CubeSats have downlinks between 435.7 and 438 MHz and reports from radio amateurs are most welcome. Beacon data received can be uploaded to a dedicated QB50 webpage at

LilacSat-1 (ON02CN), which deploys at 0815 GMT on Tuesday, May 23, is carrying a FM to Codec2-BPSK Digital Voice transponder, an APRS digipeater and camera. Further information at

Two of the ISS QB50 CubeSats deployed in the first phase, ON01FR 437.020 MHz and ON05FR 436.880 MHz, carry V/U FM transponders. The uplink frequency for both is 145.860 MHz with 210.7 Hz CTCSS, see http://site.amsat-f.org/2017/05/12/qb50-document-de-description-des-telemesures-des-satellites-on01fr-on05fr/

CQ Magazine honours Britons involved in Astro Pi project

Radio amateurs David Honess, M6DNT, and Tim Peake, KG5BVI / GB1SS, have been inducted into the prestigious CQ Amateur Radio Hall of Fame.

The CQ Amateur Radio Hall of Fame honours those individuals, whether licenced radio amateurs or not, who have made significant contributions to amateur radio; and those amateurs who have made significant contributions either to amateur radio, to their professional careers or to some other aspect of life on our planet.

David Honess, M6DNT, developed the Astro Pi project which sent two Raspberry Pi computers to the International Space Station as platforms for students on Earth to write and run their own computer code in space. In November 2016 he was honored for this work with the Sir Arthur Clarke Award, presented by the Arthur C. Clarke Foundation and the British Interplanetary Society.

David said “I was really surprised when I heard I’d been inducted into the Hall of Fame, especially alongside Tim! Thank you to CQ magazine for the honour.”

“I’m so jealous of the kids these days, if you could have sent BBC Basic code to the Mir space station when I was kid I would have gone mad for it! Astro Pi gives young people a chance to be real ISS scientists, to have their code run in space and do something meaningful.”

UK astronaut Tim Peake, KG5BVI /GB1SS, coordinated the International Space Station end of the Astro Pi project.

Tim was very active in the ARISS program during his mission on the ISS. In his free time he used the amateur radio station in the Columbus module to talk to students at schools in the UK and around the world. These contacts included the first use of Digital Amateur Television (DATV) transmissions to schools from space.

Founded in 1975 AMSAT-UK is a voluntary organisation that supports the design and building of equipment for amateur radio satellites.

AMSAT-UK initially produced a short bulletin called OSCAR News to give members advice on amateur satellite communications. Since those early days OSCAR News has grown in size and the print quality has improved beyond recognition. Today, OSCAR News is produced as a high-quality quarterly colour A4 magazine consisting of up to 40 pages of news, information and comment about amateur radio space communications.

The new lower-cost E-membership provides OSCAR News as a downloadable PDF file giving members the freedom to read it on their Tablets or Smartphones anytime, anyplace, anywhere.

LilacSat-1 CubeSat to deploy from ISS

Students installing antennas at BY2HIT

The student built LilacSat-1 carries an amateur radio 145/436 MHz FM to Codec2-BPSK digital voice transponder, APRS Digipeater and camera.

LilacSat-1 CubeSatThe satellite was developed at the Harbin Institute of Technology and is part of the QB50 mission which aims to study the lower thermosphere. Deployment from the International Space Station is planned for 0815 GMT on Tuesday, May 23, 2017.

The main payload is an ion and neutral particle mass spectrometer (INMS) developed by the University of London (UCL) to measure the mass and distribution of charged and neutral atoms.

In preparation for the deployment HIT students have been busy working on installing new VHF and UHF antennas for the ground station.

Nexø II Rocket – Onboard Video

The rocket Nexø II is planned to launch this summer. Radio amateur Alexandru Csete OZ9AEC describes the video system which uses the Raspberry Pi.

The long-term aim of the project is to launch a human into space, and bringing them safely back to Earth. Nexø II will be launched from a floating platform in the Baltic Sea east of Denmark.

This second vlog is a status on the video system of the Nexø II rocket planned for launch this summer. The Nexø II is a progression on the Nexø I now with a DPR system. One more addition is a new camera system containing three cameras. Here Alex Csete OZ9AEC (the designer) tells more about the setup and design.

Copenhagen Suborbitals is the world’s only crewed, amateur space program, 100% crowdfunded and nonprofit. In the future, one of us will fly to space on a home built rocket.

JY1SAT applies for frequency coordination

JY1SAT LogoThe JY1SAT CubeSat is planned to launch early in 2018 and will carry a FUNcube 435/145 MHz SSB/CW transponder and Slow Scan Digital Video (SSDV) system.

The team have submitted an application to the IARU Satellite Frequency Coordination Panel which says:

JY1SAT is an educational 1U CubeSat project with the goal of providing an actual space project for Jordanian University students. Additionally it is intended to enthuse and educate young people about radio, space, physics and electronics.

The spacecraft will only require simple groundstation antennas and an SDR dongle receiver. This will make it uncomplicated for schools and colleges to use with their students. It is anticipated JY1SAT will be launched into a Sun Synchronous Low Earth Orbit about 450-600km. In such an orbit the satellite passes over Jordan at least twice a day.

The student team will develop and operate a special groundstation for this spacecraft. As well as having BPSK telemetry, JYISAT will be able to transmit pre-stored images of the Kingdom which will be selected by national competition. These images will be downlinked using a novel digital format based upon the existing SSDV system.

It will additionally carry a FUNcube UHF to VHF linear transponder that will have up to 0.5 watt output and which can be used by Radio Amateurs worldwide for SSB and CW communications.

Requesting a telemetry downlink on 145.840 MHz and transponder downlink passband on 145.855-145.875 MHz with an inverting uplink on 435.100 – 435.120 MHz.

Planning a launch in Q1 2018 from Vandenberg on a SpaceX flight.
