We are sorry to have to tell you of the death of Brian Lynch EI9HY. Brian died three weeks ago after a short illness. To his wife Eileen and to his three daughters we extend our deepest sympathy. May he rest in peace.

Important Anniversary

Tuesday last marked the 60th Anniversary of the conclusion of the conference of the International Telecommunications Union held in Atlantic City in 1947. The outcome of this conference was very beneficial to the amateur community. A new HF band was obtained at 21 MHz and above 30 MHz the basic structure of the amateur bands up to 10 GHz was established. This included the VHF 2 metre band and the UHF 70 cm band together with the microwave bands at 13 cms (2.4 GHz), 6cms (5.7 GHz) and 3 cms (10 GHz).

Space Anniversary

Thursday last marked the 50th anniversary of the launch of the first artificial Earth satellite. Sputnik 1 was launched by the USSR on the 4th of October 1957. The 59-centimetre aluminium sphere weighed 84 kgs, had four aerials protruding from the back and took about 98 minutes to orbit the earth. The satellite carried batteries, which accounted for most of the weight and two radio transmitters. These transmitters sent pulsed signals on 20.005 MHz and 40.005 MHz and the length of these pulsed signals varied depending on the satellites temperature and internal pressure.

Radio amateurs throughout the world monitored the signals from Sputnik 1 and the signals heard on Radio Eireann here were recorded at an amateur station in Dublin. The batteries in the satellite ran out after three weeks on the 26th of October. The satellite re-entered the Earth’s atmosphere after three months and burned up on the 4th of January 1958 after about 1450 orbits of the Earth. It is interesting to note that just four years after the launch of Sputnik 1 the first amateur satellite Oscar 1 was put into orbit by the American Air Force on one of its rockets. This satellite orbited the earth for 22 days transmitting the familiar "HI"greeting in CW.

Mike has become synonymous with many of the most memorable DXpeditions: Most recently, he was a CW operator and Team Physician of the BS7H activation of Scarborough Reef. The talk begins at eight o’clock in the COBRAS meeting room in the Shorts Social Club on Holywood Road, Belfast and all Visitors are very welcome to come along.


As you no doubt heard, CQIR caused quite a stir on the bands last weekend. Despite poor propagation conditions on the Saturday, Irish stations on all continents were worked by the Society's headquarters station EI75IRTS from their location in the Phoenix Park. The team had erected a rhombic antenna with five wavelength legs at a height of 65 feet beamed on the states and this helped counter the poor propagation. The station made eleven hundred QSO’s in the 24 hours of the Contest and to date over a hundred logs have been received for the event from around the world. Our thanks to all the EI and GI stations who participated and remember to get your logs in as soon as possible for inclusion in the draw. Details of how to submit your log are available on the IRTS website.

AREN supports Charity walk

AREN members Declan Horan, EI9FVB and Conor O Neill, EI4JN supported a walk in aid of the Irish Heart Foundation on Saturday 29 September last. The walk in the McGillicudy Reeks was led by Conor who radioed regular reports to Declan through the Cork repeater. Declan operated from his home QTH in Ballicollig Co. Cork. The walkers encountered thick fog on the ascent, which later cleared, giving way to clear skies and spectacular views.

Marconi Clifden Celebrations

On the 17th of October 1907 Guglielmo Marconi sent his first commercial message from the then new station at Clifden, Ireland.
