Towards the end of the year radio amateurs will have the opportunity to receive what must be the ultimate DX from a ham radio payload transmitting the data mode JT65B as it flies around the Moon.

Beijing plans to send a lunar orbiter around the Moon carrying a 14 kg battery powered payload known as 4M-LXS which was developed at LuxSpace. The amateur radio payload will transmit a JT65B signal on 145.990 MHz which can be decoded by radio amateurs using the free WJST software.

The orbiter is one of the test models for Beijing’s new lunar probe Chang’e-5, which will be tasked with landing on the moon, collecting samples and returning to Earth. The launch, planned for 4th quarter 2014, is aimed at testing the technologies that are vital for the success of Chang’e-5. The orbiter will be launched into Lunar Transfer Orbit (LTO) then will perform a flyby around the Moon and re-enter the Earth’s atmosphere after 9 days.

TabletSat-Aurora launched with 11 other satellites carrying amateur radio payloads from Dombarovsky near Yasny on Thursday, June 19, 2014.

The D-STAR GMSK Parrot (Store and Forward) Repeater can store up to 8 seconds of voice message and runs 0.8 watts to a whip antenna.

There are two other transceivers on the satellite, they transmit GMSK telemetry data on 435.550 MHz and 436.100 MHz. Their power can be varied by command from the ground station between 0.8 and 2.0 watts. TabletSat-Aurora is also a downlink on 8192 MHz.

Dmitry Pashkov R4UAB reports the test on his website at http://r4uab.ru/?p=7160

Online WebSDR for VHF Satellites

144 MHz prototype helix antenna

144 MHz prototype helix antenna

You can use the free online SUWS Web Software Defined Radio (WebSDR) from your PC or Laptop to receive the International Space Station (ISS) and the many amateur radio satellites transmitting in the 145.800 – 146.000 MHz band.

Martin Ehrenfried G8JNJ has equipped the SUWS WebSDR with omni-direction helix antennas for both 144 and 432 MHz which have proved effective for both high altitude balloon and satellite reception.

The SUWS WebSDR is located at Farnham not far from London, listen to it at http://websdr.suws.org.uk/

Martin says this about the special satellite antennas “I had been experimenting with single turn ‘twisted halo’ design, and decided to try stacking them to see if I could achieve more gain. Modelling suggested that a stretched 3 turn helix with a helix circumference of approx 1/2 wave length and an overall length of 1/2 wave at 70cm, and fed with a gamma match at the centre would offer reasonable gain, an omni-directional pattern and mixed polarisation.”

Full details of the antennas are available at

The FUNcube telemetry transmitter has been enabled on 145.915 MHz (+/- Doppler) as part of the commissioning program for UKube-1 which is presently underway.

Whilst the existing FUNcube-1 Dashboard does not correctly display the FUNcube-2 telemetry, it is forwarding the data correctly to the Warehouse and this is greatly appreciated by the team.

The FUNcube team are not yet able to release a FUNcube-2 specific Dashboard App, they are, however, working to provide a fully functional FUNcube-2 page on the Data Warehouse as soon as possible.

In the meantime please continue to listen and, where you are able, to keep the data flowing to the Data Warehouse – many thanks for your support.

EMF 2012 badge of attendee Graham Shirville G3VZV

There will be an amateur radio village and special event station GB2EMF at the Electromagnetic Field EMF 2014 event taking place August 29-31 at Bletchley near Milton Keynes.

EMF 2014 is a festival for anyone interested in radio, electronics, space, homebrewing, robots, UAVs, 3D printing, DIYBio, Internet culture or pretty much anything else you can think of. It is a volunteer effort by a non-profit group, inspired by European and US hacker camps like Chaos Communication Camp, HAR, and toorcamp.

Imagine a camping festival with a power grid and high-speed internet access; a temporary village of geeks, crafters, and technology enthusiasts that’s lit up by night, and buzzing with activity during the day. Over a thousand curious people will descend on the friendly open space to learn, share, and talk about what they love.

Over a long weekend, you can expect to see a huge variety of talks across three stages, a slew of workshops, as well as music, games, and installations dotted around the site.

Attendees are invited to set up their own villages — camps within the camp — where like-minded people can camp together and put on their own activities. The hard-working EMF team of volunteers will supply you with power and internet to your tent.

The special event station GB2EMF will be run from the Amateur Radio Village, it had been hoped to have a 70cm/2m crossband FM repeater operational during the event but it looks as though Ofcom licensing issues may preclude this.

At each EMF event the organisers try and give the attendees a great camp badge. Not just a ‘Hello my name is” sticker but a nice fun piece of technology that they can take away and use after the event.

EMF 2014 takes place August 29-31 near Newton Longville, just South of Bletchley, Milton Keynes, MK17 0BU. Talks include:
• High Altitude Ballooning by Adam Greig M0RND
• Amateur Radio – Practical Sign offs by Paul
• Amateur Radio: The Original Nerd Hobby! by Ryan Sayre 2E0RYS
• An Operator’s Guide to the Enigma Cipher Machine by Simon Singh
• Back to Basics Radio – build a self-powered solderless receiver by Iain Sharp
• InfraRed Communications by Michael Turner
• Surface Mount Soldering – SMD by hand isn’t hard, build your own Persistence of Vision kit to prove it! by Edinburgh Hacklab

NASA Announces Next Opportunity for CubeSat Space Missions

SpaceX Dragon grappled by ISS  Canadarm2 2012-10-10

Space X Dragon Spacecraft

NASA is opening the next round of its CubeSat Launch Initiative, part of the White House Maker Initiative, in an effort to engage the growing community of space enthusiasts that can contribute to NASA’s space exploration goals.

The CubeSat Launch Initiative gives students, teachers and faculty a chance to get hands-on flight hardware development experience in the process of designing, building and operating small research satellites. It also provides a low-cost pathway to space for research in the areas of science, exploration, technology development, education or operations consistent with NASA’s Strategic Plan.

Applicants must submit their proposals electronically by 4:30 p.m. EST, Nov. 25. NASA will select the payloads by Feb. 6, 2015, but selection does not guarantee a launch opportunity. Selected experiments are slated to be flown as auxiliary payloads on agency rocket launches or be deployed from the International Space Station beginning in 2015 and running through 2018. NASA does not provide funding for the development of the small satellites and this opportunity is open only to U.S. non-profit organizations and accredited educational organizations.

One goal of the CubeSat Launch Initiative is extend the successes of space exploration to all 50 states by launching a small satellite from at least one participant in each state in the next five years. To this end, NASA is particularly focused this round on gaining participation in the District of Columbia, Puerto Rico, and 21 states not previously selected for the CubeSat Launch Initiative. These states are: Arkansas, Delaware, Georgia, Idaho, Iowa, Kansas, Maine, Minnesota, Mississippi, Nebraska, Nevada, New Hampshire, New Jersey, North Carolina, Oklahoma, Oregon, South Carolina, South Dakota, Washington, West Virginia, and Wyoming.

CubeSats are in a class of research spacecraft called nanosatellites. The base CubeSat dimensions are about 4x4x4 inches (10x10x11 centimeters), which equals one “Cube,” or 1U. CubeSats supported by this launch effort include volumes of 1U, 2U, 3U, and 6U. CubeSats of 1U, 2U and 3U size typically have a mass of about three pounds (1.33 kilograms) per 1U Cube. A 6U CubeSat typically has a mass of about 26.5 pounds (12 kilograms). The CubeSat’s final mass depends on which deployment method is selected.

To date, NASA has selected 114 CubeSats from 29 states, 17 of which have already been launched. Nine more CubeSats are scheduled to go into space in the next 12 months
