Camb-Hams Satellite Operation from Islay Island

Camb-Hams LogoMembers of the Camb-Hams will once again be active on the amateur radio satellites as GS3PYE/P, but this time from Islay Island between May 6-12.

The Camb-Hams have been activating the Scottish Isles each year since 2008.

As in the past, ten or more operators will be active on all bands and many modes from 4 m to 80 m, 2 m & 70 cm for Satellites and 2 m and 23 cm for EME.

The HF bands will be covered by four simultaneous stations while the 6 m and 4 m stations will have a great take-off towards the UK and Europe. All stations will be able to run at the full UK power limit.

EME operations will use 150W to 55 elements on 23cm and 400W to 17 elements on 2m, primarily on JT65, but also available for CW skeds – if your station is big enough.

Satellite operations on 2 m and 70 cm will use X-Quad antennas and a fully automatic Az/El tracking system. Activity is planned on AO-7 (mode B), FO-29, SO-50, AO-85 & AO-73.

All the up-to-date plans and progress and sked info will be on-line at
http://dx.camb-hams.com/

Most importantly, this is a group of good friends doing what they enjoy, so please give them a call and enjoy the trip with them.

Active on the major social networks before, during and after the trip, you can check on progress and interact with the operators via their blog or through the Twitter, Facebook and YouTube links below:

Low-Cost 10 GHz SSB Receiver

Graham G8HAJ demonstrating 10 GHz SSB

Despite the Bank Holiday Essex Skills Night attracted 55 people to the Danbury Village Hall on April 17, 2017. The busy evening consisted of a wide range of activities, among them was 10 GHz SSB by Graham G8HAJ.

Low-cost 10 GHz SSB receiver

He demonstrated how you can start with a simple low-cost 10 GHz receiver using a just a standard Sky satellite LNB (£14:99) and a FUNcube Pro+ SDR or RTL-SDR dongle. This set-up should be capable of receiving the amateur radio transponder on the geostationary satellite Es’Hail 2 that is expected to be launched in early 2018.

The Es’Hail transponder should be receivable on a 60 cm dish with no tracking needed. The downlink will be 10489.550-10489.800 MHz which will equate to 739.550-739.800 MHz on an SDR with the Optima LNB down-converter.

For 10 GHz transmit Graham showed the popular DB6NT transverter and interface board which used an IF of 144 MHz.

Israeli High School Students Build CubeSat

28 QB50 CubeSats were launched to ISS on April 18, a further 8 are to launch on a PSLV in May

28 QB50 CubeSats were launched to ISS on April 18, a further 8 are to launch on a PSLV in May

Over 80 Israeli high school students have built a CubeSat called Duchifat-2 as part of the QB50 Thermosphere research program.

Duchifat-2 is one of 28 QB50 CubeSats from 23 countries launched on April 18, 2017 to the International Space Station (ISS) from where they shall be placed into orbit in six weeks time.

QB50 ISS LogoSpace Watch reports:

Duchifat-2 and its companion CubeSats will measure the plasma density of the Thermosphere between 85km and 300km altitude above the Earth’s surface. Israeli students will study the data from the CubeSats at the Herzliya Science Centre, where signals from the orbiting satellites will be received.

Israeli Minister for Science, Technology, and Space, Ofir Akunis, said in a government statement that, “Duchifat-2 is not only an educational venture that brings space closer to youth and lays the way for tomorrow’s generation, it is also an international research project. This is Israeli pride for the future generation, and an opportunity to increase public awareness about space.”

A further eight QB50 CubeSats are planned to launch in May on an Indian PSLV rocket into a 500 km orbit.

All the CubeSats in the QB50 project will mainly operate on frequencies in the 2 m and 70 cm amateur bands. To avoid interference to terrestrial amateur radio activity the frequency was coordinated by the IARU Satellite Adviser and advisory panel http://amsat.org.uk/iaru

PocketQube Workshop presentation slides released

OzQube-1 LogoIn March Stuart McAndrew gave a presentation on OzQube-1 a tiny PocketQube satellite which aims to transmit images of the Earth from space.

OzQube-1 will be just 5x5x5 cm (1P) in size and the aim is to keep the hardware costs down to under $1,000. The satellite structure is being developed by Jo Hinchliffe MW6CYK.

Stuart’s talk titled ‘Building a Satellite from Scratch: The DIY Engineering behind OzQube-1’ describes some of the challenges he’s faced in building his own low-cost satellite.

South African QB50 CubeSats

CubeSats being deployed from the ISS on February 11, 2014

CubeSats being deployed from the ISS on February 11, 2014

Two South African built satellites are about to be launched to the International Space Station as part of the QB50 project.

SARL News reports:

The South African satellite industry is taking another step forward as a player in the international space arena with the launch of two South African built nanosatellites from Cape Canaveral in Florida USA.

Two CubeSats, ‘nSight1’ (QB50 AZ02) designed and manufactured by Cape Town-based SCS Space, a member of the SCS Aerospace Group and ‘ZA-Aerosat’ (QB50 AZ01) designed and manufactured by CubeSpace of the Stellenbosch University, are to be launched as part of a batch totaling 28 CubeSats from 23 different countries

The launch is set for April 18, 2017 at 15:11 GMT. Their initial destination is the International Space Station (ISS), where they will be unloaded by the ISS crew with the help of robotic arms. The satellites will eventually be deployed into low-earth orbit over a period of 30 to 60 days as the ISS orbits the Earth.

Both the South African satellites are part of the QB50 project funded by the European Union and managed by the von Karman Institute to conduct research in the lower thermosphere between 200 to 380 km altitude. The data collected from this experiment over a period of 18 months will be used to complement current atmospheric models especially applicable to re-entry trajectories of spacecraft. All CubeSats will eventually burn up at the end of their operational lifetimes.

All the CubeSats in the QB50 project will mainly operate on frequencies in the 2 m and 70 cm amateur bands. To avoid interference to terrestrial amateur radio activity the frequency was coordinated by the IARU Satellite Adviser and his advisory panel http://amsat.org.uk/iaru
