At the LRS meeting on 12th February Dr Roger Hill talked about "Robot Wars + Rampaging Chariots  and showed videos of robots in combat. He wrote: 

"Peter Bennett, (who was present at Roger's talk) once a test pilot, gathered a team of engineers from Selex (now Leonardo) to assist in building a family of robots to compete in the BBC ‘Robot Wars’ programme. Typhoon 2 won the heavyweight title of the 7th BBC series in 2006. Peter then designed a simpler robot called the Rampaging Chariot, to compete in the British Robotic Games where it won 27 of 42 medals at its first outing held in Wigan. In this talk, I describe the engineering features of these and other micro-controller-based projects".

Pete Bates GM4BYF talked about Aircraft Scatter Communication and Useful Test Equipment for it at the  meeting on 22nd January 2020. 

Aircraft scatter can be used on bands from 2m upwards and up to 500km range is achievable, depending on the band and geography. The talk started with some audio examples of aircraft scatter - available in the full report.

The requirements for an accurate frequency reference led to the purchase of some cheap test equipment which has many other uses.

There was a turn-out of 15 for the LRS 2020 Video Night, presented by Peter Dick GM4DTH on 8th January 2020 at the Edinburgh Cine & Video Society in Fettes Row. Peter chose two films about the Cold War.

Spy in Bonn receiving a "Numbers Station".

The first was a short (14 min) from ITN Roving Reports called "The Spy Catchers" (1963). The setting is Bonn in West Germany and gives an indication of the level of espionage from the communist bloc.

Western propaganda stations targeting the USSR

The second film was called "Empire of Noise" (2006) and ran for 50 min. The title refers to the sound of the jamming modulation used by Soviet jamming stations in the short-wave broadcast bands prior to the fall of the Soviet Union in 1990. With jamming modulation playing throughout the film this was a realistic but really depressing view of the world of SW broadcasting in the 1950s onwards, fortunately now gone forever.

At the meeting of the LRS on 30th Oct 2019. Nick Peckett G4KUX/YA4F talked about Rehabilitating Telecommunications in Afghanistan. 

Nick lived and worked in Afghanistan from 1998 for the Islamic Emirate of Afghanistan (Taliban Government) and later governments, until retirement in 2008 but continued as a consultant until 2017. He described his major involvement in the development, and rehabilitation after 9/11, of many types of commercial systems including satellite-based mesh, cellular, microwave trunk routes and undersea fibre portals.

He also operated Amateur Radio mostly on 50MHz as YA4F and talked about his experiences there.  

Nick's talk was illustrated by many photographs taken all over Afghanistan showing the challenging geography and the microwave towers he designed and erected.

Nick now lives in County Durham and is active on the VHF to microwave bands with a well-equipped station.
