Michaelmas 2010

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)!

“Sunspots and the Solar Dynamo” talk

This Thursday (4th February) sees our first speaker meeting of term.

Professor Michael Proctor from the Department of Applied Mathematics and Theoretical Physics will speak on “Sunspots and the Solar Dynamo”.

“Professor Proctor will describe the physical and periodic properties of sunspots covering their magnetic characteristics and average 22 year cycle. He will describe the knowledge of surface and sub-surface solar behaviour gained from helio-seismography and the latest thinking on the underlying mechanisms responsible for generating the intense toroidal magnetic fields implied by the periodic appearance of sunspot pairs.”

The talk will start at 1900 in the Bateman Auditorium, Gonville and Caius College (see map for location in the college). Doors will be open from 1845. I look forward to seeing as many of you as possible there.

Following the speaker meeting on Thursday, there will be an informal CUWS gathering at the Maypole (see map
for location) from 2000. I hope you will be able to make it for a drink and a chat.

Good luck to those taking licence examinations tomorrow.

Best wishes,

Jordan

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.

“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.
