MLPS is trying to raise money to buy the Planet, restore her to her original specifications and keep her on Merseyside. The special event raised over £100 to save the lightship and also marked the Queen’s Golden Jubilee year. With the latter aim in mind, GB2LBL was attempting to contact other stations in the Commonwealth: the event started well with the first SSB contact to Tasmania and the first on CW to Alice Springs. Despite ‘local QRM’ from the maintenance crew hammering right outside the shack, the two stations went on to make contacts with the Turks and Caicos islands, Gibraltar, Cyprus, Malta, and Canada, as well as dozens of other countries. Other interesting contacts included another lightship in the harbour at Keele, Germany, and a cargo ship off Port Elizabeth, South Africa. Members of the public were invited on board to sign the visitors’ book and very generously donated to the collecting bucket. The group wishes to thank ML&S and Kenwood (UK) for their help. MLPS is looking for new members (at £5 a year) and for individual and corporate donations to help to save the Planet: please see the website at www.barlightvessel.org.uk Donations / membership subscriptions can be sent to Bill Harrison, Treasurer, 2 Mount House Road, Formby, Merseyside L37 3LB or for more information contact chairman Stan McNally, tel: 0151 648 2266. M3 ‘QSO Party’ A Big Success THE M3 QSO Party on 40m on 1 January was a huge success with hundreds of newly-licensed M3 amateurs and their friends wanting to join in. Richard Jolliffe, G3ZGC, said: “I planned just to join in but when I switched on there were two M3s looking for a net controller. So as one of the Newbury club’s Foundation Licence instructors I volunteered. Now there are 6000 licensed M3s, so even if only 1 in 10 decided to join I realised that there could be a big response. The actual pile-up was certainly the largest I have ever heard and I had to go to letters in the suffix and ask for M3 Alfa stations and work through the alphabet. In two hours I worked 112. At least half as many again were gotaways.” Richard added, “What was very noticeable was that the standard of operating was fantastic by the M3s although some full licensees left a lot to be desired. It was noticeable how appreciative most of the M3s were at having passed their exams. Many messages of thanks were passed to their local clubs. An excellent event.” Douglas Nixon, M3BKC, was one of the numerous Foundation Licensees joining in the fun. He said, “Richard did a splendid job as net controller during the hectic conditions that followed at times during the next two hours. Roger, G4RUW, also from Newbury, took over at 1200, followed by John, G4TSN, from Nottingham. Many thanks to all concerned.” Another Mountain to Climb ON 1 JANUARY South Africa became the seventh country to have a ‘Summits on the Air’ (SOTA) scheme. SOTA is an award scheme that encourages portable operation from hilltops. It started in March 2002 with schemes in England and Wales, which were joined by the Isle of Man, Italy, Scotland and Northern Ireland. SOTA has proved very popular and already nearly 400 summit expeditions to over 180 summits have taken place in the UK. The Republic of Ireland is expected to be the next country to join - by St Patrick’s Day, 17 March. Full details are at http://www.sota.org.uk 10 THE ‘THREE Counties’ Foundation Course Group based at Frodsham in Cheshire completed its 10th course in November last year.

The station will be part of an exhibition to be opened by the Duke of Edinburgh at the Dunes Entertainment Centre in Mablethorpe. The Duke visited Mablethorpe and Sutton-on-Sea immediately after the flood, and saw the devastation at first hand. The role played by amateur radio during this time was pivotal to the setting-up of Raynet. Humber Radio, GKZ, had to close down due to flooding. Amateurs continued to monitor the distress frequencies of 500 and 2182kHz, and Cliff Newby, G3EBH, was one of a number of amateurs who worked out-of-band to answer shipping in distress, and was then able to co-ordinate with the Coast Guard service. Amateurs also helped the emergency services ascertain the scale of the disaster. David Hopcroft, station manager at Humber Radio, wrote the following in an article on the The Mablethorpe Dunes Entertainment Centre, home of GB0ERG and the east coast flood exhibition. history of Humber Radio: “On the night of 31 January 1953 the staff on duty, though used to handling Distress traffic, suddenly found themselves to be in distress. During severe gales at a period of high tides, the sea broke through the coastal defences and flooded the station that was located just behind sandhills close to the sea. Urgency (XXX) traffic was in progress with MV Levenwood in difficulties in rough seas when the power failed. Very shortly after the emergency genPhoto: David Hopcroft, Humber Radio The 1953 temporary Coastal Radio Station near Louth. erator also failed. The last entry in the WT log reads ‘GNF de GKZ, Station Flooding, Ceasing Operations’. . . The whole of the district was by now under water. The sea had broken through defences in many places, not only in this area but also other parts of the country and across in Holland. Services were resumed a few days later using the mobile station set up for just such an emergency. It was a converted bus parked on a hill some 15 miles inland. Permanent repairs took about six months before ‘normal service was resumed’.” The Eagle Radio Group also plans to put on a display of 1950s equipment at the exhibition to demonstrate the technical changes which have taken place over the last 50 years. An article on the 50 years of amateur radio emergency service will be published in RadCom next month. National Science Week, 7 - 16 March NATIONAL SCIENCE Week takes place this year between 7 and 16 March. This is an ideal opportunity for radio clubs or groups of individuals to put on a special event station to demonstrate amateur radio to the general public. The RSGB has produced a whole series of posters and leaflets to help you to put on a successful event. These include press release letterheads to give your press release a professional look, A3 and A2 size posters, and even amateur radio lectures on paper, acetates or PowerPoint. You supply the manpower: we will help 5DG&RP ♦ )HEUXDU\ with the rest. Contact RSGB HQ by 14 February at the latest to state your requirements. As part of National Science Week, GB4FUN will be touring the country demonstrating amateur radio. ● GB4FUN recently visited The Priory Lincoln School of Science and Technology following a request by teacher Dave Mackinder, G4DWP. In what was seen as one of the most successful visits by GB4FUN yet, the year 7 pupils passed greetings messages to amateurs on HF and used the computer-controlled satellite tracking equipment on board the van. The demonstration was such a success that a new after-school amateur radio club is being formed and there is a waiting list for the first Foundation Course at the beginning of next term! The visit was reported by the Lincoln Chronicle and generated much good publicity for amateur radio.

When I connected it to an ariel I soon discovered it was the Dual Band Radio. The first radio I have seen to be able to monitor 2 Airband signals at the same time. Pagers do not seem to bother it at all. The remote head puts all the controls where you want them. The mike can completely operate the radio (including frequency entry and DTMF). If you want a serious dual band radio with excellent scanning facilities then the IC-2725 is ideal.

Compiled by Steve Hartley, G0FUW A GOOD MIXED BAG of news this month with lots of photos. Please keep your news rolling in, the contributions are always welcome. YOUNGSTERS STEAL THE SHOW EVERY YEAR the Trowbridge & District Amateur Radio Club runs a construction challenge for its members. This year the club stalwarts were swept aside by three newcomers who took the top three prizes! The prize-winners are three of four very keen young amateurs. I am told that Freya Shirley, M3FES, aged 13, is the tidy one. Her other interests include playing the piano and horse riding. Camilla Shirley, M3CGS, aged 11 is the talkative one and, like her older sister, also enjoys horse riding and the piano. Ethan Shirley, M3BVK, is the ‘baby’ of the gang at 8 years of age. Ethan had only just turned 8 when he did the Foundation exam and, after causing all the others a lot of stress, he walked away with a score of 19 out of 20. Well done Ethan! Last, but not least, comes Peter Robertson, M3BPG, aged 11, who was the first of the group to take the exam. Peter is a Star Wars nut and enjoys playing computer games. Camilla takes up the story: “On our first visit to the local amateur radio club we all entered into the Constructor’s Cup. Peter won with his amplifier project, Freya came second with a short-wave receiver and Ethan was placed third with his crystal radio set. Now we are all licensed amateur radio operators and are on the air. Currently we are only on the 2m (144MHz) band until we all get a more substantial radio station”. If you would like to read more about their achievements you can access the full newsletter at www.gb3wr.co.uk/foundation/ I think all readers will join in the congratulations to this very keen band of newcomers. MORE ON SMALL LOOPS DAVID BERRY, G4DDW, is no newcomer to amateur radio or to this column but he continues to chip in ideas for those who are just finding their way in the hobby. His latest idea is for a really small loop antenna. David reports that during some experimentation he made a mistake but ended up with an antenna that works well on all bands from 7 to 21MHz. He now regularly works SM5AEA in Stockholm on 14MHz and has contacted many UK stations on 7MHz using the new antenna.

Five young ladies and nine boys attended the course run by the Carrick Amateur Radio Group and all 14 were successful. Not only was this the first course at 1919 Squadron but the first at any ATC Squadron in Northern Ireland. It seems that the successes at Newtownabbey have stirred up more interest with requests for courses now coming in from other ATC units. Looks like the instructors Eddie, MI0ALS; John, GI0USX; and John, GI3YRL, are going to have their hands full in 2003!

One aspect which has not featured prominently for some time, however, is the use of amateur radio for developing foreign language skills. Recent changes in the licensing rules and the welcome influx of younger M3 Foundation Licensees, many of whom are still pursuing academic studies, make this a good time to reflect on how we might give greater emphasis to this important aspect of the hobby. As someone who has been a long-standing student of the French language - for more years than I care to remember - I have to say that whenever conventional language students outside amateur radio see the facilities we have for live, on-air language practice, the reaction is often one of disbelief. The opportunity for voice and text contact with foreign nationals who share similar interests to our own is something we frequently undervalue. Like many other UK Francophile operators, I use 80 and 40m and the lower portion of the 20m SSB segment to make contact with French radio amateurs. The contacts can be mutually advantageous in the sense that the language used can easily be switched according to need. English is used if French amateurs wish to practice their hardlearned vocabulary, and French is used if British operators wish to test their language skills. In practice, the operator with the weaker vocabulary tends to defer quickly and lapse into his or her own language, but this need not always be so. Experience has shown that the simple request to be allowed to continue in the other language will almost certainly be met with patience, cour* 20A Pear Tree Road, Ashford, Middlesex TW15 1PW; e-mail: nshackley@btinternet.com 56 by Norman Shackley, G0OSX * Amateur radio is an absolutely ideal medium for improving your school French or German, or for brushing up on your Spanish before your next holiday to the Costas or the Canaries. Yet very few UK amateurs, at least, take advantage of the wonderful opportunities provided by our hobby, relying instead on the overseas amateurs’ ability to speak English. Norman Shackley, G0OSX, says “Try something new in amateur radio!” and provides a number of ideas based around using your foreign language skills. Saint-Jean - a watermill in the hamlet of Polincove in the Pas de Calais, the first mill activated on the day described in the text. tesy and a genuine willingness to assist. In fairness to overseas operators, however, this can only work in the longer term if language students do their homework before going on air. In this respect, foreign language development in amateur radio is really no different from the long-standing approach to good radio operating practice in general. Putting the microphone away and listening to experienced foreign amateur operators will frequently ensure better progress than bulldozing one’s way into a QSO, ill-prepared and inadequately equipped linguistically for a meaningful two-way exchange of information. Perhaps a closer parallel to good learning practice is the building-block approach to learning the Morse code - which is itself a language, after all. Many of the good linguists in amateur radio first started foreign language QSOs using the simple, rubber-stamp exchanges. Typically, they then progressed to more detailed contacts by steadily expanding their QSO vocabulary using those increasingly common expressions ‘lifted’ from the valuable listening sessions mentioned above. If the commitment is there, before too long a facility is developed for dealing with standard radio exchanges and the operator begins to cope with increasing confidence when pushed to the limits of a restricted vocabulary. Speak to any radio amateur who has scaled the language barrier at whatever level and in whatever language and all will agree on one thing. The satisfaction and pleasure they now gain from the hobby makes all the months and years of effort worthwhile. At the present time several UK operators are regularly active working stations across the channel. Harry, G0CSS, from Nottingham can be heard most days, as can Ray, G0RKQ, in Scunthorpe. Ray has for many years enjoyed regular QSOs with Patrick, F5RXE, from Castillonla-Bataille in the Bordeaux region of south west France. On the French side, Henri Lohier, F5MDM, a retired air force officer and dedicated Anglophile who has been studying English for six years, actively seeks and is always delighted to make contact with UK stations to supplement his conventional language studies. If any reader would like to register an interest in developing language skills through amateur radio I would be happy to co-ordinate replies and put like-minded members in touch with Les Allwood, G3VQO, setting up the 40m mobile antenna on the 4 x 4 by the windmill in the village of Watten. 5DG&RP ♦ )HEUXDU\ WHERE TO LOOK WHERE CAN YOU FIND foreign-speaking radio amateurs to practise your language skills? The answer is, of course, all over all of the HF bands. But certain nationalities tend to congregate around specific frequencies so specific languages can often be heard in particular parts of the bands, particularly on 20m. Here are a few - if you have details of others, please send them in to RadCom. Français French 80m (all), 40m (all), 20m 14120 - 14130kHz Deutsch German 80m (all), 40m (all), 20m (all) Ελληνικα Greek 20m 14285kHz± Svenska Swedish 20m 14300 - 14310kHz each other under the various language groupings. FRENCH AWARDS PROGRAMMES FOR ANY English-speaking operator wishing to develop language skills and radio links with French operators directly, the awards programme organised by REF-Union (the French equivalent of the RSGB) offers real opportunities for regular contacts. Awards such as the regional departments award (DDFM - Le Diplôme des Départements Français de la Metropole); the French castles award (DFCF - Le Diplôme des Forts et Chateaux de France) and the French windmill and watermill award (DMF Le Diplôme des Moulins de France) all provide real operating challenges, combined with the opportunity to improve language skills for those wishing to do so. In all of these award programmes, the level of French language required for a successful contact can be as simple or as complex as desired. They therefore make an ideal starter-pack for the aspiring linguist. TILTING AT WINDMILLS MY OWN INTEREST in the DMF award was triggered by Les Allwood, G3VQO, following a 40m contact in May 2002, when he was operating as F/G3VQO/P from a windmill in the Pas de Calais region of northern France. The ensuing QSL and e-mail correspondence spoke of the detailed preparations involved in identifying and locating mills suitable for activation by invading Brits from this side of the channel. I expressed an interest in learning more about the DMF 5DG&RP ♦ )HEUXDU\ and was quickly invited to join the next trip planned for November 2002. And so it was that I found myself one dark, Saturday morning in Horsham, Sussex, at 0420, shaking hands with G3VQO. After brief introductions we climbed into a 4 x 4 and set off for Folkestone and the 0630 crosschannel tunnel departure for Calais. We quickly cleared Calais port controls by 0830 French time, and were rolling through the French countryside just 15 minutes later. The day’s activities called for a number of skills, all of which were amply demonstrated by G3VQO: map reading, antenna assembly and adjustment, language skills for operating as well as for seeking route directions as a last resort (some mills were so remote that not even all local residents were aware of their existence). Even natural history knowledge was tested on occasions as we tried to identify the wealth of wildlife observed during the course of the day. Under the rules of the DMF award programme, the portable station can be located up to 500 metres from the mill. In practice, we were able to set up the station immediately adjacent to the mill in most cases. Les was adept at springing into action and converting the 4 x 4 into a working station within minutes. The equipment used for the project was a Yaesu FT-847, powered by a 110Ah 12V Leisure battery with a variety of HF whip antennas available for connection to a magmount on the roof of the vehicle. Only five of the planned six mills were activated due to time constraints. In the course of the day we operated mainly on 40m SSB, providing award contacts for predominantly French and Belgian DMF enthusiasts, but with a respectable smattering of UK stations coming in strongly, together with other European callsigns. During the inevitable quiet spells, Les quickly switched to CW and gained a number of rapid Morse contacts including one of particular interest with Sergei Rebrov, M0SDX, the Tottenham Hotspur premier league footballer. Sergei was enjoying a break from premiership football by spending a day on the rig to participate in the Ukraine National CW Contest. The last QSO was logged at 1610, after which we closed down the station and headed back to Calais for the 1730 tunnel departure. We arrived back in Folkestone at 1615 UK time, a return which enabled me to be back home in Ashford, Middlesex, by 1830. ONE THING LEADS TO ANOTHER . . . WOULD I CONSIDER doing it again? I certainly would. The benefits of overseas operating in this unusual but very popular award programme are many and varied. I particularly enjoyed the strengthening of links with French operators on their home soil in the true spirit of amateur radio. Being able to operate in the French countryside was most enjoyable, as our surroundings were always pleasant. Perhaps most of all I enjoyed the getting up and about and trying some- Les Allwood, G3VQO, at the mill at Inglinghem. thing different in amateur radio for a change, a step I had not taken for many years. The reward here was being able to watch a skilled CW operator at close quarters. Les Allwood, G3VQO, belongs to the French UFT (L’Union Française des Télégraphistes), membership of which requires a set number of successful French-language CW contacts with, and nomination by, other UFT operators. Not unexpectedly, the experience has fired my ambition to follow suit and since my return I have been busy brushing up my CW French-language vocabulary. Would I want to change anything the next time I go over? I would certainly want to reward myself just a little more for all of those many DMF award contacts issued. I would also like to benefit from the location, once the radios have been safely stowed away, by tucking in to a large meal with lots of good wine, ideally in the company of a few French operators to do our bit for L’Entente Cordiale, followed by an overnight stay in a comfortable hotel! ♦ WWW.

Intermediate Licence - Building on the Foundation draws heavily on the decade of success enjoyed by the Novice Licence scheme and in particular the Novice Student’s Notebook by John Case, GW4HWR. However, this is more than a new edition with it adopting the easy to read and understand style of the hugely popular Foundation Licence - Now, that many readers will be familiar with. The book is broken down into manageable half-hour worksheets and contains practical exercises along with plenty of helpful advice and safety tips.
