(UPDATE – Based on claimed raw scores we are 1st in the U.K. in the Multi-Single category.)

A team of operators manned Woop Woop 3 for the CQWW SSB Contest over the weekend of October 27/28. 2443 contacts were made for a claimed score of just over 2.3M points in the Multi-Single category. The 40m 4-square antenna and the 80m vertical will probably be left up for members to use over the winter.

The antennas are shown below: 80m vertical, 40m 4-square, 5 element 15m Yagi on 40ft SCAM, and regular 3 ele SteppIR in distance.

Life Member Rob, G3YZO, operated and brought along this picture of the original Woop Woop building in Grange Road which the club vacated in 1970. It was an ionospheric research lab before it was taken over by CUWS. Note that it wasn’t the first club shack – that was in the Old Cavendish in town.

CUWS Uses G6XX during the World Cup – June 2018

CUWS used the special RSGB Contest Club callsign G6XX on a couple of days during the football World Cup Championship in June. Ops included G3ZAY, M0WUT, M0ZCJ, G7VJR, M/KD2LXA, 2E0FFC, 2E0XSM, M0VFC, M0WJE, M0BLF, and M1BXF. Around 1500 contacts were made with up to 3 stations QRV simultaneously.

Welcome to all our members, old and new, to the new year.

There are a number of activities planned this term, with more to come.

Firstly, to our new members, if you haven’t yet had a chance to visit the shack contact Martin G3ZAY who is arranging visits. Also anyone who is interested in taking any level of Amateur Radio exam in Cambridge (student or not) should contact Martin for details.

At the end of October is the CQWW DX SSB contest, in which we usually make a competitive entry (for the past two years we have set new English records in our category). Contact Dom M0BLF for more information or to find out how you can get involved with operating.
If you want to see what the contest is about, but don’t fancy operating, then feel free to come along to the shack any time on the 27th or 28th October to see the contest in action.
Volunteers are also needed the weekend before, and the Monday and Friday either side of, the contest to assist in erecting and then dismantling the additional antennas we use for the event.

If you would like to start contesting with something a bit easier, we also enter the weekly RSGB UKAC – these are contests on VHF and UHF bands which last for 2.5 hours every Tuesday evening. Feel free to come along and join in (or just watch!)

Also this month is the annual RSGB convention, to which a number of our members will be going and some presenting. There are a number of talks on a variety of subjects, and tickets are available on the door if you are interested in joining them.

Finally, every Thursday we have an informal meeting in the Maypole pub at 8pm, which is a great chance to get to know fellow amateurs in the area. It is also a great chance to ask questions about almost anything technical – our members have interests and expertise ranging from mathematics to electronics, engineering and computer science!

If you have any questions, please feel free to contact me at

Welcome to the Cambridge University Wireless Society, and welcome back for a new year to our existing members!

Want to read more about what we do? Look at our introductory page. We’re planning an introductory talk about the society on Thursday 14th October and to show people around our radio shack on the Sunday after (17th).

This term sees the annual Radio Society of Great Britain convention, to which we’ll be sending a contingent (and you’re welcome to join them), as well as the annual CQ World Wide SSB contest, into which we regularly put a competitive entry. We’re also looking at a talk and a trip to Bletchley Park later in the term. See our event calendar for more details.

Thanks to the efforts of the volunteers who have done the ground work, and to the generosity of our donors, we have a brand new shack building to which the finishing touches are now being put, and which you should go and see once it’s ready! The club shack is there to allow all licensed members to get on the radio and make contacts around the world without having to acquire your own equipment or find space for antennae in central Cambridge. It’s nearby and a great resource. Don’t forget that we’re always willing to help people obtain amateur radio licences.

I very much hope to see you at one of our events, or perhaps at one of our weekly informal pub meets (Thursday, 2000, The Maypole)!

Lent term 2010

Happy new year and welcome back to Cambridge for those who have been away!

We have a number of events lined up for this term.


    • On Thursday 4th February, at 1900, Professor Michael Proctor of the Department of Applied Mathematics and Theoretical Physics will speak on “Sunspots and the solar dynamo”
    • On Thursday 25th February, at 1900, Dr David Sadler of Roke Manor Research will speak on “HF direction finding and superresolution techniques”
    • On Thursday 4th March, at 1900, Robert Chipperfield (M0VFC) will speak on “RAYNET: the what, why and how of amateur radio emergency communications”


All talks will be in the Bateman auditorium at Gonville and Caius college, with doors open by 1845.

Our weekly pub meets, from 2000 each Thursday in the Maypole, continue.

Martin (G3ZAY) and Michael (G7VJR) will be on air in the Falkland Islands from 21st to 29th January, and we shall have an organised visit to our radio shack to make contact with them. Look out for more details on this!

I look forward to seeing/hearing some of you later on in the term!


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!


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

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.

DXCC League Table

This is a new feature for the website designed to encourage a little competition between members and to see how people are doing chasing new countries.

The figures given are worked totals as peoples’ confirmed totals often depend quite greatly on how long they have been active and how much has been invested in direct QSLing. Unless otherwise stated, these figures were correct as of 20th January 2007.

Anyone else wishing to be included in the table, please e-mail me your totals and I will include them. I will publish new totals every three months or so depending on interest and activity.
