Terry Ransome - Yuri Gargarin & the Chief Designer

Terry Ransome

31 members gathered to hear a fascinating talk about the early days of the space race from a Russian perspective. Yuri Gagarin was the first man to orbit the earth.

Terry Ransome -Beagle to Mars via Kazakstan and Filton !

 Terry Ransome

When all hope of ever hearing from Beagle 2 on Mars was officially abandoned Terry Ransome was one of the few that hoped maybe not. Terry met Prof Colin Pillinger in the Marconi Space offices in Filton in the mid 90s, and put together the first ideas for a verification and test programme to fly a UKbuilt lander to Mars. Colin's dream eventually came to fruition, and eventually Terry took Beagle 2 to Baikonur for launch and was the last person on Earth to touch the Probe before it headed off to Mars in 2003. Terry told of his delight at visiting the Baikonur Cosmodrome, some of the untold secrets of what actually happens in a launch campaign, and how Beagle2 was finally found.

Ian Greenshields - 5 Mhz

Ian G4FSU

Ian is the IARU technical consultant and also the RSGB HF manager. We now have access to around 70Khz of the band at 5Mhz. Ian will explain propagation on the band and highlight some of the unusual features, such as being able to communicate with military cadet stations. There is no IARU band plan and communicating with other countries can be fraught with traps of being outside our allocation.

We heard him talk on the latter subject last year. At that meeting, he revealed that he was planning to return to making amateur radio equipment, something he did with some success during the 1980s with his Company, muTek Limited.
