Prince Kuevor who worked on the CADRE CubeSat features in a video from the University of Michigan Aerospace Engineering Department.

The CADRE 3U CubeSat, developed by the students at the University of Michigan, was launched to the ISS on December 6, 2015 and should be deployed from the space station soon, possibly mid-May. It carries an instrument package developed by the Naval Research Lab, WINCS, which will characterize neutral winds and ion drifts in the ionosphere/ thermosphere. The IARU lists the downlinks as 437.485 MHz and 3404.0 MHz.

What is it like to be an aerospace engineering student at the University of Michigan? Step into the life of senior Prince Kuevor, who, in addition to his coursework, writes software for CADRE, a small satellite designed by his student team. In the future, Prince hopes to become a professor and teach the next generation of aerospace engineers.

The OUFTI-1 D-STAR CubeSat team have released the format of the CW telemetry beacon and a Decoder App. The launch, on a Russian Soyuz-STA Fregat-M from Kourou in South America, is expected to take place at 21:02:13 UT on Saturday, April 23, 2016.

OUFTI-1 is a nano-satellite entirely developed by the students of the University of Liege (ULg), Belgium, along with two other engineering schools. It is the first satellite to carry a dedicated amateur radio D-STAR transponder.

Listen to Tim Peake on 2m FM

UK astronaut Tim Peake KG5BVI GB1SS in the ISS Jan 2016

UK astronaut Tim Peake KG5BVI / GB1SS

UK radio amateurs have the chance to listen to Tim Peake GB1SS transmitting on 145.800 MHz FM from the International Space Station (ISS).

The dates of Tim’s planned UK school contacts are at https://amsat-uk.org/2016/02/03/all-uk-ariss-shortlisted-schools-are-now-scheduled/

All you need to hear Tim is a 144 MHz handheld radio, such as the popular £16 BaoFeng UV-5R VHF/UHF transceiver. If used outdoors you should be able to hear Tim with just the tiny antenna supplied with the handheld. If you have a 1/4 wave whip you will get better results.

In the UK we use narrow 2.5 kHz deviation FM but the ISS transmits on 145.800 MHz with the wider 5 kHz deviation used in much of the world. Most base station and mobile radios can be switched been wide and narrow deviation FM filters and for best results you should select the wider filter. Handheld radios all seem to have a single wide filter fitted as standard.

As a result of Doppler shift the 145.800 MHz ISS signal may vary by +/- 3.5 kHz during a pass going from 145.835 to 145.7965 MHz. Many FM radios can only tune in steps of 5 kHz, with such equipment you may get best results by selecting 145.805 at start of pass, then 145.800 and finally 145.795 MHz.

Not got a VHF radio or not in the UK ? You can tune-in to Tim Peake online from anywhere in the world using the SUWS amateur radio WebSDR receiver located at Farnham near London http://websdr.suws.org.uk/

There will be a live video webstream of Tim Peake’s UK school contacts at

Catch the signal of e-st@r-II CubeSat

Catch est@r-II CubeSat Signal CompetitionThe CubeSat Team of Politecnico di Torino invite the amateur radio community to participate in a competition to receive the 437.485 MHz signal from their new satellite e-st@r-II which launches 2102 UT on Monday, April 25, 2016 on a Russian Soyuz-STA Fregat-M rocket from Kourou in South America.

The CubeSat Team is a student team of Politecnico di Torino involved in the design and development of small platforms for scientific missions and for testing new technologies. We are guys enthralled by space activities. Undergraduate and graduate students work together with researchers and professors to create a real hands-on experience.

“SPACE IN A CUBE: MISSIONS OF THE FUTURE” is our motto! We believe that small satellites can contribute to a broad set of science goals and space based services. Our CubeSat missions aim at conceiving new scenarios and technologies to serve the scientific community while educating students in the challenging field of aerospace engineering.

Our first CubeSat, e-st@r-I, was launched into orbit on February 2012, and the second satellite, e-st@r-II, will be launched next week: the Soyuz launch ST-A VS14 is scheduled on April 25, 2016, at exactly 09:02:13 p.m UT, from the European Kourou spaceport in South America http://www.arianespace.com/mission/ariane-flight-vs14/

To celebrate this date, we invite the radio-ham community to support the e-st@r-II mission: participate in the contest to listen out for our CubeSat from orbit!

We have prizes for the first to receive the e-st@r-II signal and for the one who will provide us with the higher number of packets received in the first month in orbit!

All details of the competition can be found at our official webpage:

Thank you in advance for your help in collecting TLM packets….. and break a leg!

RSGB amateur radio video – a world of possibilities

The Radio Society of Great Britain have released a new amateur radio promotional video which features amateur radio satellites.

Amateur radio is a hobby with so many aspects it can be hard to describe – and difficult to know what to try first! We’ve tried to give a taster of just some of the many exciting, challenging and fun things you can do with amateur radio. We’re planning to take a look at other parts of the hobby in the future – what’s your favourite?

Watch RSGB amateur radio video – a world of possibilities

Among those featured in the video is the RSGB VHF Manager John Regnault G4SWX. He will be giving a talk titled “Introducing Moon Bounce” at 7:30pm on Tuesday, May 3 to the Chelmsford Amateur Radio Society (CARS). The meeting will take place at the Oaklands Museum, Moulsham Street, CM2 9AQ. Car parking and admittance are free, visitors are most welcome http://g0mwt.org.uk/future-meetings
