  • Airborne Maritime Surveillance Radar by Simon Watts, G3XXH

    22nd November 2018 @ 8:00 PM - 10:30 PM
    Woodford Park Leisure Centre, Haddon Dr, Woodley, Reading RG5 4LY, UK

    Simon Watts G3XXH joins us to give us a brief history of RAF ASV radars from 1940 to 2010.

    The history of airborne radars developed in the UK for long range maritime surveillance by the RAF spans from 1940, when ASV Mk. I entered service on Sunderland and Hudson aircraft, through to the 1980s, when the Searchwater radar entered service on the Nimrod MR2. This history came to an end in 2010 when the Nimrod MRA4 programme was cancelled and the Nimrod MR2 taken out of service.

    The early radars operated at VHF. Following the development of the high power magnetron, operation moved to S-band and then to X band. Searchwater was a complete departure from earlier radars, incorporating a TWT transmitter, modern signal and data processing and computer control. This talk will give an overview of the design and evolution of these radars, the aircraft they were used in and the performance they achieved, detecting ships and submarines.

    We (Simon M0ZSU + committee flunkies) will bring along all the items (as far as reasonable) the club has for loan. Test equipment focused. Can see there's much point bringing the SCAM-12 mast or Clark mast.

    Demonstrations of equipment likely.

  • Charles Wheatstone - Musician and Inventor by Colin McEwen

    24th January 2019 @ 8:00 PM - 10:30 PM
    Woodford Park Leisure Centre, Haddon Dr, Woodley, Reading RG5 4LY, UK

    This talk explores some of the less well-known aspects of Charles Wheatstone's life and achievements.

    Charles Wheatstone was born in 1806 near Gloucester. He was the son of a music seller. He started his working life as apprentice to his uncle, a flute maker, but by 1834 his contributions to science led to his appointment as professor at King's College London [aged 28].

    Wheatstone worked on many topics, including acoustics, telegraphs, measurements, and cryptography. Tonight's talk looks at his work on railway telegraphs and invention of the Wheatstone concertina [usually known today as the English concertina].

    Wheatstone worked with W F Cooke [at Cooke's request] to develop the 5-needle railway telegraph, leading to its installation on the Great Western Railway between Paddington and Slough in 1838. It was only in service for a year, until the insulation failed, but it was a major advance at the time.

    Wheatstone retained his interest in music and his first patent on the English concertina was filed in 1829. Wheatstone subsequently set up a concertina manufacturing and sales business which produced thousands of instruments. Many of the concertinas have survived and are playable today.

  • Mirages and Angels: the effects of atmospheric refractive index on electromagnetic wave

    14th March 2019 @ 8:00 PM - 10:30 PM
    Woodford Park Leisure Centre, Haddon Dr, Woodley, Reading RG5 4LY, UK

    David Hooper joins us from STFC Rutherford Appleton Laboratory to tell us all about the effects of atmospheric refractive index on electromagnetic waves.

    David says "there was some really nice work done during the 1960s, which turned out to be relevant for helping me to understand what I was seeing with my 46.5 MHz radar".

    More details soon.
