At around 10-11am on Sunday, June 28, 2015 Andrew Garratt M0NRD and the South Kesteven Amateur Radio Society are planning to launch balloons from the 10th World Egg Throwing Championship held at the Swaton Vintage Day at Swaton, near Sleaford, Lincolnshire.
As well as telemetry data it is also planned to transmit Slow Scan Digital Video images in 434 MHz. Depending on altitude the signals from a balloon may have a range of up to 800 km, potentially covering much of the British Isles. A real-time track with altitude will be displayed online at http://tracker.habhub.org/
Andrew provided this information on the UKHAS Mailing List : First ever flights for me, so in at the deep end. The ‘egg’ payload will be carried aloft by the balloon and will have a parachute decent into the North Sea when the balloon eventually bursts. There will be SSDV and backup tracker, kindly sponsored by MADHEN http://madhen.net/
