Introductory meeting

Want to know what we get up to? Meet at 1900 on Thursday 15th October outside Queens’ porters lodge for a lift to our radio shack, to see what you can do with us!

There’s no need to tell us in advance that you’ll be coming, but an email to chairman@g6uw.org will ensure we know not to drive away without you! (If there’s nobody waiting and it looks as if we have gone, please telephone 07748 873900.)

If the 15th isn’t convenient for you, we’re happy to arrange a tour at another time: please email chairman@g6uw.org to make arrangements.

Jordan Skittrall, Chair

“Supersonics, RF Harmonics, Digital Electronics and Teddy Bears” Talk

The poster for the combined CUWS and Caius Engineering Society talk by CU Spaceflight on “Supersonics, RF Harmonics, Digital Electronics and Teddy Bears” can be found here.

This promises to be a fascinating overview of the CU Spaceflight project with insights into some of the technical challenges the team has faced and how they’ve overcome them to make the project such a success. The speakers will touch on rocketry, ‘near-space’ ballooning, digital radio communication, global positioning and much more.

The talk takes place on Thursday 5 March at 7.00pm in the Bateman Auditorium at Caius College. Entry is free and non-society members are most welcome to attend.

More information about the project can be found on the CU Spaceflight website.

The presentation which Henry, Ed and Fergus gave at the talk can be downloaded as a pdf file here.

Ascension Island (ZD8): 2009

Six CUWS members (Martin G3ZAY, Michael G7VJR, Tom M0TJH, Gordon G3USR, Simon G4EAG and Hugo M0HSW) were on the air as ZD8UW from Ascension Island (AF-003) between 1 January and 9 January 2009. We were active on all HF bands, both SSB and CW.

We were on Green Mountain, with a clear view to the horizon from about 210 degrees to 45 degrees. Other paths were totally blocked by the mountain.

QSL info:

We don’t need your card if you don’t need ours! If you are happy with an LoTW confirmation then please save the planet.

CUWS Societies Fair Leaflet 2008

This year’s version of the CUWS Societies Fair leaflet is now available for download here. The leaflet gives useful background information on the society and some of our recent events. If you’re interested in finding out more about CUWS, this is essential reading!

Constitution Online

As a result of a suggestion at the 2008 CUWS AGM, the Society’s constitution is now available online in the Meeting Minutes section of the website. Minutes of recent Society meetings can also be found on the same page.

GB75UW

GB75UW was a special event station celebrating the 75th anniversary of the Cambridge University Wireless Society’s callsign, G6UW. Between 1 December 2007 and 28 December 2007, a total of 1,700 QSOs were made. If you need to QSL, please bear in mind that all QSOs will automatically receive a QSL card. For direct QSLs, please route to G7VJR (see qrz.com).

The Cambridge University Wireless Society was founded in 1920 and its original members included Professor Sir Ernest Rutherford (now known for his work on nuclear physics but originally a radio researcher) and Professor EV Appleton (known for his discovery of ionospheric layers, made while he was a CUWS member). Other members have included Dr J.A. Ratcliffe (ionospheric researcher), Professor Sir Maurice Wilkes G5VF (ionospheric researcher and builder of EDSAC, the first practical stored program computer), Dr JB Gunn (inventor of the Gunn Diode), and Professor Sir Martin Ryle G3CY (Astronomer Royal and inventor of aperture synthesis radio astronomy techniques). Professors Rutherford, Appleton and Ryle are all Nobel Prize winners.

CUWS members made substantial contributions to the development of radar and other key technologies during World War 2 and have since played many leading roles in British industry and academia. Cross fertilisation of ideas in the British scientific establishment is evidenced by Professor Ryle’s citing of Professor Wilkes’s contribution to the use of computing in radio-astronomy in Cambridge.

CUWS is one of the last university amateur radio clubs active on a regular basis in the United Kingdom, and is a source of practical training for the RCF/Ofcom radio exams for university members and the public, as well as an active HF DX and contest club.
