On October 25 Ghislain Ruy LX2RG provided this update on the 4M lunar amateur radio payload.

Signals from 4M are quite weak. This is not due to a loss of power as telemetry shows normal parameters, but to the attitude of the last stage that places a deep of the radiation pattern in the direction of the Earth. I hope that Earth’s movement with respect to the inertial attitude of the last stage will give better results in the coming days.

The 4M is becoming a real challenge now, and receiving the signals during flyby will be quite an achievement. A little bit away from the original goal though, but this risk was known.

One sure result is the radiation measurement that showed what was to be expected, and the graphs will soon be pubished on the blog.

I hope you will be able to receive during the AMSAT-DL AGM this weekend, but you will have to put 16+dB [antenna] gain at least.

Radio amateurs are encouraged to receive and report the signals http://moon.luxspace.lu/receiving-4m/

NoV suggestion for Airborne Ham Radio

Ofcom-logo-col-tThe RSGB response to the Ofcom licence consultation raises the suggestion of the use of NoV’s for aeronautical amateur radio operation.

The UK amateur radio licence currently prohibits airborne operation and amateurs have had to transmit using licence exempt spectrum instead.

The Society is critical of Ofcoms’ proposals regarding 470 kHz pointing out they do not align with the Wireless Telegraphy Act, nor are they the minimum necessary under the ITU Radio Regulations. The RSGB also say the 470 kHz proposals set a dangerous precedent in relation to interference.

Regarding the proposal to remove the 15 minute ID requirement and replace it with ‘as frequently as practicable’ the Society say it is open to too great a range of interpretation (and in some cases might be more burdensome than the well known 15-minute rule). The RSGB also suggests there is currently an ambiguity regarding embedding callsign data in modes such as Digital Voice.

In total over 2,000 people responded which is believed to be a record for an Ofcom consultation. It is thought Ofcom may take some time to publish all the responses but when they do they should be at

4M – Chang Zheng CZ-3C-G2 launch vehicle

The 4M amateur radio payload with a WSJT JT65B 145.980 MHz beacon was launched on Thursday, October 23 at 1759 UT.

The Chang’e-5-T1 mission 4M payload launched on the Chang Zheng CZ-3C/G2 rocket from the LC2 launch complex at the Xichang Satellite Launch Center, Sichuan. The first telemetry from the JT65B beacon was received at 1918 UT in Brazil.

A number of Australian radio amateurs have reported receiving the signals from 4M. Among them was Rob Whitmore VK3MQ at Mount Dandenong, Victoria (QF22qe) who reports that at best, the strength was -13 on the JT65B scale and could also be totally down into the noise with no decodes.

He says “I am using the “Before” TLE as published on the Luxspace website with Gpredict to stear my 6 element yagi and TS2000. With Doppler the frequency is 145.9787 MHz at the time of writing. So far the decodes have included callsign, telemetry and a story of Manfred Fuchs threading through alternate decodes.”

Sam Jewell G4DDK @DXING Tweeted “Had around 40 minutes of near 100% copy from the moon probe 4M transmitter from around 1725z [Oct 24]. 9 element Yagi and K3/2m on 2m /JT65B”

The spacecraft will head into a Lunar Transfer Orbit (LTO), before performing a flyby around the Moon. Radio amateurs are encouraged to receive and report the signals. http://moon.luxspace.lu/receiving-4m/

UK Students CubeSat Project

Warwick University WUSAT-2 CubeSat

Warwick University WUSAT-2 CubeSat

The Coventry Telegraph newspaper reports on students at Warwick University who are building their own satellite WUSAT-2.

Lucy Lynch writes that eight engineering students are designing their own satellite which will be sent into space. In February or March 2015 they and the project director Dr Bill Crofts will don winter woollies and take their creation to a launch site in northern Sweden, near the town of Kiruna.

It is the second student satellite designed at the university. The first one, last year, was sent up from mid Wales in a high altitude weather balloon.

Once the current satellite has been launched the next step is to create a satellite capable of orbiting the Earth.

Dr Crofts said: “This is a stepping stone to a full orbital launch.”

The LituanicaSAT team has announced on Facebook that the LituanicaSAT-2 CubeSat will be coming soon.

It is hoped the CubeSat will be among 50 satellites launched in the 1st quarter of 2016 on the Ukrainian Cyclone 4 launcher from the Alcantara launch site built by Ukraine and Brazil. The new launch site is located near the Atlantic coast of Brazil just 2.3 degrees south of the equator.

LituanicaSAT-2 will be more complex than the first and will test a new propulsion system which will enable it to change orbit.

GB1SS callsign for International Space Station

Sarah Brightman

Sarah Brightman

The RSGB report that on October 9, 2014 Ofcom confirmed that the callsign GB1SS will be made available for issue to UK astronauts who wish to operate from the ISS.

In May 1991 the first UK astronaut Helen Sharman GB1MIR talked to radio amateurs around the world from the Mir space station. After a gap of 24 years it looks as though two more UK astronauts may be flying to the International Space Station (ISS) in 2015.

One of the UK radio amateurs that Helen contacted all those years ago was Chris Lorek G4HCL he says: I remember it fondly! I and my three children all chatted with her on 2m using my club station call G4SMC (South Midlands Communications in Chandler’s Ford) on her next-but-last Mir pass over the UK before she came down. Steven (10 years old), David (8 years old) and Carolyn (5 years old) all said hello to her, each giving their name and age, with Steven asking whether there was a particular challenge she may have had. Helen replied, knowing it was very young children, that one difficult challenge she’d had was putting her socks on as she floated around the station!

In September 2015 Sarah Brightman hopes to become the 2nd UK astronaut, flying to the ISS on a 10 day mission. She is committed to encouraging young women to pursue careers in Science, Technology, Engineering, and Mathematics (STEM). In 2012 in conjunction with Virgin Galactic, she launched The Brightman STEM Scholarship program. It is not yet clear if she will operate the ISS amateur radio station during her mission.

Tim Peake KG5BVI training on ISS Amateur Radio Station Equipment

Tim Peake KG5BVI training on ISS Amateur Radio Station Equipment

Tim Peake was selected to train as an astronaut in 2009 and hopes to go to the ISS in November 2015. He holds the USA callsign KG5BVI and has recently been learning to use the Ericsson 144 MHz handheld radio which is installed in the Columbus module of the ISS. On September 18 Tim said “Will be great to chat with schools next year from space using this ham radio on board the ISS.”

There are two amateur radio stations on the ISS, one in the Russian Service Module, the other in the ESA Columbus Module. Almost any 144 MHz FM rig will receive signals from the ISS, you can even use a general coverage VHF scanner with an external antenna. As far as the antenna is concerned the simpler the better. A ¼ wave ground plane is a good antenna for the ISS as it has a high angle of radiation. Large 2m colinears may not work quite as well since the radiation pattern is concentrated at the horizon.

You can receive the ISS outdoors using a 2 metre hand-held with its helical antenna but a 1/4 wave whip will give far better results.

In the UK we use narrow 2.5 kHz deviation FM but the ISS transmits using the wider 5 kHz deviation used in much of the world. Most rigs can be switched been wide and narrow deviation filters so select the wider deviation. Hand-held rigs all seem to have a single wide filter fitted as standard.

Voice contacts with astronauts usually take place using “split” frequencies. The astronauts transmit on 145.800 MHz and listen for replies on 145.200 MHz, you just need to activate your rig’s repeater shift. Recently, however, they have also been operating simplex listening on 145.800 MHz.

When astronauts are not on the air they usually leave the packet digi-peater running on 145.825 MHz so why not listen out for it.

UKSA announces CubeSat payload opportunity

UKSA - UK Space Agency LogoThe UK Space Agency (UKSA) has announced an opportunity to fly payloads on the 3U CubeSat AlSat-1N.

AlSat-Nano is primarily an education programme, its top level objective is to teach Algerian students how to design, build and operate a 3U CubeSat. The programme involves a number of Algerian graduate students who will be hosted at the Surrey Space Centre (University of Surrey) and focuses on the development of the CubeSat as a hands-on learning exercise for the students, to demonstrate the practical implementation of this type of low cost space technology.

As well as the practical element of the programme there will be a focus on research modules around the use of low cost nano-satellite technologies and applications in developing nations such as Algeria, which would help to create sustainable growth and have practical uses such as earthresource management (agriculture, water), atmospheric monitoring, and disaster management.

The design and build of the nano-satellite will take place at Surrey Space Centre. Final assembly, integration and verification will take place at the ASAL satellite development facility in Oran, Algeria. Operations will be carried out from Oran also.

The bus will be built using hardware sourced from UK suppliers and the CubeSat will also carry payloads which will be supplied by the UK CubeSat community. These payloads will be selected in a competitive process following an Announcement of Flight Opportunity which will be issued in December 2014.

The precise interface specifications will be developed during the first trimester of the project to be integrated in the Announcement of Opportunity, however it is foreseen that a maximum volume of 1U (10cm x 10cm x 10cm) and maximum mass of 1kg will be available for payloads. The selection of the payloads will be carried out in early 2015 via a selection panel.

Payloads must be ready for functional testing and integration by September 2015. Launch will be in Q2 2016. Because of the educational and collaborative nature of the programme there are two further specific points that should be noted:
• Payload providers must be actively engaged in all programme reviews and an active participant in the consortium
• Payload providers must be willing to share payload data with the programme for research purposes, and to receive interpreted payload data via the ASAL ground segment in Oran, Algeria

Submissions should be sent to Ryan King, UK Space Agency – ryan.king@ukspaceagency.bis.gsi.gov.uk with ‘AlSat-Nano RFI’ as the subject line. The deadline for responses is 12 noon, November 14th 2014. Submissions received after this time will not be read.
