In his second talk, Brian will do a short piece about how to receive the recently-launched AMSAT Es'hail-2 geostationary satellite. He has been receiving the 10 GHz transponder output at his QTH in Peebles and has established that it can be done with quite simple gear. As it is hoped to be operational for 20 years in a geostationary orbit it could have quite an influence on amateur radio and be readily accessible.
Rx set-up: 60cm Sat TV dish, PLL LNB & SDR dongle.
Transponder passband noise as received by Brian.

14th Nov 2018 - R.V. Jones' Most Secret War - Prof. Joe McGeough
- Details
- Written by Alan GM3PSP
At the meeting of the LRS on Wed 14th Nov 2018 Prof Joe McGeough of Edinburgh University talked about 'Why Churchill Waged R.V. Jones' "Most Secret War".
During his darkest hours Prime Minister Winston Churchill turned to a young scientist, R V Jones, still in his twenties, to explain how enemy bombers were able to carry out precision bombing over Britain at night even when the skies were covered in clouds, and to find a solution. Using information from Bletchley Park and the Enigma machine there Jones provided the answers. It was the start of a close working relationship between the elderly statesman and the young scientist. Later in the war Jones devised “ Window “ using Aluminium foil to confuse the enemy radar during the D Day landings.
