Also in GB2RS this week…

A team of amateur radio astronomers from around the world have been making observations of hydrogen spectra using the G4NNS EME system near Andover as an L band radio telescope. By studying hydrogen spectra it is possible to gain insights into the shape and motion of our galaxy. It is the unexpected motion of the galaxy that gave rise to the discovery of dark matter. As part of British Science Week, between 13 and 22 March, the observatory will be open twice daily for live observations and a presentation of how the galaxy’s shape and motion can be revealed using radio astronomy. This event is free but as space in the shack is limited, it must be booked in advance by e-mail or phone. Contact or 01264 773342.

While World War I centenary activities began in 2014, the focus by the Australian community has always been on ANZAC Day, celebrated on the 25 April each year. ANZAC Day initially honoured the Australian and New Zealand Army Corp, or ANZAC, soldiers who took part in WWI, and has since been extended to commemoratively reflect on all conflicts involving Australian and New Zealand forces. The Wireless Institute of Australia, WIA is supporting the many community events being held in Australia and the Gallipoli Peninsula in Turkey, with its own ANZAC Centenary Award, special callsigns and other activities. The ANZAC 100 program coordinator is Fred Swainston, VK3DAC, who can be contacted via and further programme details are on the WIA website at

Lambda-Sat, the first Greek CubeSat, was released from the International Space Station on 4 March and its developers have invited radio amateurs around the world to listen for its signal and to file reports. The 1U CubeSat transmits AX.25-protocol UI packets at 1200bps AFSK on 437.462MHz. The 1W transmitter identifies as KK6DFZ. Lambda-Sat was constructed entirely by young volunteers from Greece, who travelled to Silicon Valley to participate in this project. More details are online at
