CQ World Wide WPX Contest 29th – 30th May 2010

Last year due to church commitments I was unable to take part in last years CQ World Wide WPX CW Contest not that I am complaining or protesting it’s important to remember the radio amateur’s code as written by Paul M Segal W9EEA, in 1928 and it still holds today and is found in the 2010 Eighty seventh edition of the American Amateur radio relay league Hand book for radio communications. Just in case you do not have a copy of the handbook to hand it reads:

The Radio amateur is:

Considerate ...never knowingly operates in such a way as to lessen the pleasure of others.

Loyal...offers loyalty, encouragement and support to other amateurs, local clubs, and the American Radio Relay league, through which Amateur radio in The united States is represented national and internationally.

Progressive...with knowledge abreast of science, a well – built and efficient station and operation above reproach.

Friendly...slow and patient operating when requested; friendly advice and counsel to the beginner; kindly assistance, cooperation and consideration for the interests of others. These are the hallmarks of the amateur spirit.

Balanced...radio is an avocation, never interfering with duties owed to family, job, school or community.

Patriotic...station and skill always ready for service to country and community.

I am sure that you would agree with me that the principles out lined eighty  two years ago hold good today and offer’s a golden standard for us all to aim for if like me you live outside the USA just replace the name of your national radio society in place of the ARRL . As far as I am aware there is not an equivalent code for the use of other means of communication if there were I am sure surfing the internet would be an outstanding experience far exciding that which we have today which unfortunately displays the worst of human nature and leading from such a base line to the heights of leading intellectual thought of our day.

For the past few weeks I had been looking forward to this year’s contest and during the week before and up to the contest I had spent some time on the bands just getting the feel of things checking out band opening’s and propagation forecasts and of course making that all important new Long distance qso and band slot with the added bonus of a new DXCC or IOTA accreditation. The last time I took part was in 2008 I finished with 200 QSO’s  This year I hoped to build upon the lessons learned and hope above all hope to increase my QSO total competing against myself to be honest this year’s  contest did not start proper for me until I had made the 2008 QSO total of 200. This target I reached at 14:21 on Saturday with RK3GYM. On Sunday morning at 09:37 I made the 300 QSO’S with S50G on 15m and I made my final QSO in this year’s contest at 13:48 on 40m with YU1LA.

Scotland Easter 2010

Scotland March - April 2010

This was our first trip up to Scotland in 2010 we booked return flyby flights from Birmingham international airport to Inverness of course this was just the main part of our journey we still had to arrange return rail travel from Oxford to Birmingham international and from Inverness to Elgin and not forgetting the taxi from Inverness airport to Inverness train station and from Elgin train station to Allison’s mum’s.  We set out in good faith that this would be a problem free journey and well worth the extra expense incurred on this style of travel for the convenience of spending less time travelling - saving time is of the essence but is it worth chucking good money at time saving means of transport – only if the mode of travel is reliable and the answer to this is no its very unreliable all kinds of factors pop up.

We arrived in plenty of time for our flight we booked in and went to the restaurant to eat and after we had time to read the papers and relax before our flight what flight – we have been here before on the same route our flight was delayed and delayed again and then again before we took off all the advantages of taking the plain had been wasted we arrived in Inverness after the train we wanted had left and we have a two hour wait to add to our discomfort there are no services open on Inverness train station the loos are closed the waiting room was cold, and unwelcoming it was the last place you wanted to be stuck at for a couple of hours.  On a bitter cold evening with snow laying deep on the hills but clear in the towns

Inverness is a city I really enjoy visiting and I will go out my way to travel on this route and visit the town I don’t feel that I have been in the Scotland unless I make it to the capital of the highlands its steeped in history from factual to made up romantic stuff woven and intermixed with a blend of storytelling and drama and I think the tourist love hearing and experiencing it  – And in some respects that’s  what they want to see I am greatly disappointed if I do not see someone wearing the national dress  or hear the pipes, whisky and haggis and tartan are the outer hall marks with other markers as well.

Leaving Allison at the train station I ventured out into the town to take some evening photographs of the river ness and the castle I had a great time but I was bothered some by the bitter cold it was a big shock to the system we had left a wonderful mild sunny day behind and walked into Narnia a wonderful winter wonderland as the shadows slowly grew longer and darker the streets around the river ness and by the castle grew very atmospheric it was easy to imagine that hiding in the dark closes off the high street were redcoat soldiers searching the streets and alley ways hunting down the Jacobite highlander the red coat solider intent on taking no quarter and the Jacobite fleeing for his life. I rejoined Allison at the train station and we took the Inverness train to Aberdeen getting off at Elgin after a short taxi ride  we arrived at Allison’s mum’s. Who was entertaining our son Peter.

Day 1

I woke in the night and I thought it was light outside so I took a peek out the curtains to be greeted by a winter scene  it was snowing heavy and laying on the ground I soon returned to my warm bed. After breakfast Peter and I walk through the snow to the train station we were booked onto the Inverness to Aberdeen train due to the poor weather condition our train was delayed in the past snow has not been a big problem on this route however flooding is a historical problem and with the railway track at the train station being submerged in water after the river Lossie has burst its banks.

The train left Elgin for Aberdeen but our journey was very slow and we were often at a standstill and then we were on the move again as we got further into speyside the snow became deeper  and the country side was covered in a deep layer of snow we finally arrived in Aberdeen safe and sound Peter and I went for lunch at a restaurant at the train station after lunch we walked down to the harbour it was bitter cold and we took some picture and made our way to the Aberdeen Maritime Museum  to dry our cameras and to get a warm up and hot drink after visiting the museum and taking some photo’s from advantage points in the museum of the harbour we went for a walk in Aberdeen itself and then made our way to the train station.

We left Aberdeen on the Inverness train but once we got past Aberdeen and into the countryside things began to change for the worse we soon arrived at Inch train station and due to frozen points we were unable to continue to Inverness there was only one way the train could go and that was back to Aberdeen between Dyce and Aberdeen we contacted my daughter and she booked us into the jury inn Aberdeen  the hotel was great four star’s all bells and whistles we went to Frankie and Bennies for dinner and star bucks for hot chocolate and coffee before returning to our hotel for the night we laid on our beds watching tv before going to bed.

As we slept safe and snug in our beds the hotel staff was at hand to take care of our wants and wishes the storm across Scotland grew wilder casing disruption to overnight travellers regardless of the mode of travel. With major travel disruption between Edinburgh and Inverness one train came to a Holt in the Drumochter moor pass and got stuck in the deep snow drifts the train its crew and passengers all needed to be rescued not an easy task for the rescuers and I am sure from the early morning new reports that Peter and I saw all stranded passengers had endured a very uncomfortable night and were only to pleased to arrived at Inverness and to get some rest at the station hotel before continuing their journey.

Day 2

After breakfast Peter and I made our way to Aberdeen train station it came as no surprise to us that the train station information boards were announcing that all trains were delayed check for further information we made our way to the ticket sale’s and booking office This was to be the only time we would witness Scot rails customers being treated in a disrespectful and rude manner by Scot rail staff. It soon became very evident that the possibility of the line between Aberdeen and Inverness being open due to frozen points at inch station was not going to be resolved any time soon and we thought that at this stage in the day we would be wiser if we checked at the coach station to see if the Aberdeen to Inverness coach was running as this followed the coastal route and stood a good chance of being open. In contrast to the scot rail staff the stage coach staff went out there way to help the stranded train customers offering advice and assistance to our delight the coastal route was open and a coach was due to leave within half an hour some hours later we arrived safely back to Elgin if a day late.

Day 3

After breakfast Peter and I made our way to Elgin train station we were booked on the train from Elgin to Inverness there we were to expect some travel disruption as alternative trains were cancelled however the one we were booked onto was going to run if only delayed by half an hour our journey to Inverness went smoothly once in Inverness Peter and I took advantage of the free time to take some photographs of the castle and river ness before going for lunch at the highland view restaurant  after lunch we made our way to the Inverness coach station we had pre booked onto a boat trip down loch ness  Called Discovery this promised a 3.5 hour coach and cruise of Loch Ness with 1 hour at Urquhart Castle

  • Spend one and a half hours cruising the Loch and the Caledonian Canal
  • look for hidden happenings beneath the water with the new Jacobite sonar
  • Visit Urquhart Castle and its fascinating Visitor Centre
  • All admissions included in the ticket price
  • Enjoy a guided coach tour

Sounds great and it lived up to its advertisement Peter and I had a great time and we made the most of the photo opportunity that this trip brought our way it’s one thing to travel down the loch on the road stopping at advantage points to admire the view but it’s much better to be on the loch in a boat our first view of Urquhart castle were breath taking all my photographs can be seen at the following link http://www.flickr.com/photos/m3jfm/collections/

Day 4

Peter and I walked into Elgin and we visit the Elgin model railway exhibition at the town hall this an annual event and one we have been to in the past this time however there was fewer exhibitors by trade stands and model lay outs but we have an interesting time and took a few photo’s of the lay outs that took our interest. After lunch Peter and I took the local town bus from Elgin down speyside to Dufftown we had heard reports that the snow was very deep down speyside and we wanted to see for ourselves also a visit to Glenfiddich distillery makes an for an interesting diversion on all accounts we were not to be disappointed the tour of Glenfiddich was very interesting afterwards Peter and I enjoyed afternoon tea Scottish highland style in the new Glenfiddich distillery restaurant. Afterwards we walked in the snow from the distillery up into Dufftown before returning to Elgin on the bus. Once in Elgin we changed buses and went down to Lossiemouth all in same afternoon   we walked in the snow on speyside and in the sunshine on Lossiemouth beach.

Day 5

Sadly it was time to make the return trip home Allison and I took the train from Elgin to Inverness and a taxi from Inverness to the airport I had a hour free to spend taking some photo’s in old Inverness and the castle before heading to the airport our return trip was problem free Inverness - Birmingham then train back to Oxford. Peter remained for a few more days at Grans and took advantage of returning to Lossie to take some more photos.

The MKARS 80M QRP Transceiver

My long awaited MKARS 80M QRP Transceiver kit arrived first post on Saturday morning I was keen to open the parcel and see what was inside I had wondered what I had let myself in for. I was pleased to see that the kit arrived complete with printed circuit board all components, knobs and a metal box to put the completed transceiver in. All the bits and bobs were packed inside the metal box for safe keeping.

Day 1

I download a copy of construction manual from http://www.radio-kits.co.uk/mkars80page.html I was careful to keep a copy of the pdf file on the desk top of my laptop as well as printing of a paper copy some 25 pages long and in full colour. following the construction manual I set to work I opened the components bag number one and started soldering the components in order onto the printed circuit panel. The printed circuit board looked like this

DSC_0524

Day 2 On Sunday afternoon for a couple of hours between afternoon tea and dinner I thought that I would like to spend a couple of hours working on the MKARS 80m Kit adding the components from bag 2. Some 42 components added and this is how the printed circuit board looked

DSC_0558

The printed circut board at the end of Day 2

Next I opened bag number 3 I soldered onto the printed circuit board the two 33v 400mw Zener diodes and then started soldering onto the board the 100nf ceramic capacitors I had time to solder 40 of them onto the board before it was time to stop for dinner. I have 11 more to solder onto the printed circuit board and one 10uh Axial inductor before I have to start winding inductors and transformers.

Day three and I had reached the stage when it was time to start winding the transformers and soldering them onto the printed circuit board the first one I had to wind was the BN43–2402 5T Trifilar wound 38 SWG ECW this did not look easy but by taking my time I was soon getting into the hang of it I used my test meter to help identify the pairs of wires that I was going to soldier onto the printed circuit board.  Before the evening was out I has also wound one of the toroids and added to the printed circut board. Having already wound and solider onto the print circit board T1 this left me to wind L2 and L4

DSC_0591

The printed circut board at the end of Day 3

Day 4 I continued winding the last three toroid's L4 was the same as L1 – Cut off approximately 40cm of 27
SWG wire and pass half of it through the center of a T37-6 core, this counts as the first turn. Now wind a further 14 turns through the core using one end of the wire, turn the core over and wind the other end through the core 15 times

making a total of 30 turns. Whilst winding pull the wire tight so the turns lay touching each other. Crop the wires to 10 – 20mm in length and tin the ends with solder. next I wound L2 is wound in a similar way with the same 27 SWG wire but has a total of 32 turns. Keep the turns tight but it doesn’t matter if several turns overlap. and last I wound L5 – using approximately 50cm of 33 SWG wire and wind using the same procedure as the other toroid cores with a total of 40 turns, space the wires evenly around the core.

This took me about 45 minutes to wind and then soldier onto the printed circuit board I was surprised that this operation took me so long I was not rushing but then I was not hanging about. The next job on the list was to solider onto the printed circuit board the Electrolytic capacitors which are polarised so may only be fitted one way round. By convention the PCB is marked with a + symbol, the + lead of a capacitor is longest, the capacitor sleeve is also normally marked -. Fit the capacitors against the PCB with zero lead length but it is very important not to put excessive force on the leads as this can make the electrolyte leak out.

Day 5

And its time to open bag 4 and fit the following IC3  is a 78L05 and IC4 is a 78L08 IC1 is a LM386N-1 next the 1N4148 Diodes a total of 15. Diodes are polarised devices so can only be fitted one way round, match the band on one end of the encapsulation with the bar printed on the PCB. followed by adding the 1N5401 Diode.

MKARS80 Day 4

The printed circuit board after bag three componets have been added to the board.and the completed board.
