PW 144MHz QRP Contest Results 1983 to 1990

Hi, my name is steve and my callsign is g1ybb.

As a keen fan of the PW 144MHz QRP Contest I have taken it upon myself to enter all the historical results that pre-date those available on the official site, in order to pass that information over to Colin at PW.

So the below PDFs are the results as I have entered them into a spreadsheet from the best records I could find. Most of from old copies of the magazines, some are scans (like 1990 and one or two). What I am looking for is ANYONE who was active in these contests to take a look and let me know any cock ups and typos, also any extra info they might have.

You can see the content varies often. This is mostly due to the content published in the magazine being different often. Usually there is a list of all callsigns and points, and tables with top 10 this and top ten that etc.

Please contact me using my email which is my name in the 1st line of this page @ my callsign in the 1st line of this page with .uk on the end. (not .co.uk)

Disclaimer:
I have nothing at all to do with Practical Wireless magazine or its parent company/companies. I merely have a fond affinity with this contest (most likely due to the fact it was my first ever contest in 1990) and an OCD nature that requires the records to be complete. 73.

Plugging yagi dipole ends to waterproof them

When making my yagis I like to plug the ends of the tubular dipoles so water cannot run down the tube and enter the dipole housing with its corrosive end results.

Many people do not like to add caps to the elements for concerns over altering resonance, so I just cut the cap off and push them in so they are fully inside but water cannot enter. Simples.

Accurately cutting yagi elements to size

I planned to build more 144MHz & 432MHz DK7ZB yagis for contesting to use in arrays so I wanted to ensure I could make them accurately and repeatedly and also without taking forever doing it! Thus I needed to come up with an efficient cutting jig.

I would use some threaded bar to adjust and set the length and steel angle for the supporting the aluminium tube and cutting the length. First I calculated the range of length between the longest reflector and the shortest director then a quick knock up in Solidworks gave me the length of stud required and ideal places to weld the angle to do the cutting. The studding is M12 because a nut for M12 will take a 10mm ali tube with a little clearance. The long M12 barrel nut (Screwfix, few pence) is locktighted in place. From the left the angle brackets have the following holes: 12.5, M12 tapped, 10.5, 10.5, 10.5:
144MHz element cutting jig

Some cutting, drilling and tapping later and I have this (the observant will note it’s not exactly the same as the intended design-more on that accidental stroke of luck later!):
cutting jig completed
Usage is very straightforward. First I G-clamp it to the bench then I used one piece of spare element tube as the setting piece, doing all elements in sequence, longest to shortest. So I set the jig and adjust, cutting and filing the setting piece until spot on then do all elements that length then onto the next element size using the same setting piece. Simple, but more importantly, very accurate and repeatable. I did try calculating the distance a fraction of a turn would give based on the thread pitch but with a simple tapped hole the thread backlash made it too unpredictable so found it easier to measure the amount the cutting piece protruded when setting for the next size down with the small vernier in the photos above and start from that point and fine tune on the thread and lock nuts.

To actually cut the elements (after using the jig to prepare one end of all elements to ensure it was nice and square and deburred) I just slide it through the 10.5 clearance holes into the long nut and hold it pressed against the long nut with one hand. With the hacksaw tilted slightly to start a cut just away from the steel angle to prevent sawing the face of the steel angle I start cutting then as soon as the cut is started square up the hacksaw. Cutting takes a few seconds:
element sawn rough size
Then it takes a few seconds more to file the element down flush to the steel angle. Over MANY elements the steel angle will gradually file down in thickness but such a large area and so much harder than the aluminium it will not affect the length between a batch (I checked):
element filed to size
Next to just finish off the end. In the picture above you will notice the countersink bit in the screwdriver handle and a pencil sharpener. Both employed very quickly to deburr inside and outside edges:
element finished end
The only thing left to do is check the length! I am lucky that my place of work happens to have a very large digital vernier. These will do, close enough for G1YBB…
882mm close enough1027mm close enough
Obviously most people won’t have such a measuring tool but it shows the jig can enable accurate results, more accurate than we can normally measure. I belive working as accurately as possible to follow the simulated design will enable the best possible results to be achieved. I have had fantastic results with my first 9 element DK7ZB working to that ethos.

About that lucky error in placement of the angles with the holes…
One thing I forgot to allow for when designing the jig was the driven dipole halves! But by a stroke of good luck (MOST unusual for me) fitting the middle guide hole angle in the reversed place turned out it was perfectly positioned for the dipole half:
driven half cut

I’ll be able make the 432MHz element cutting jig to cater for dipole halves and full elements easily because the threaded bar covers enough length with the 70cms elements being so small.

G1YBB Contest round up 2017

2017 was was first full year back into VHF contesting (and some HF contesting too) since the 1990s. In 2016 I did the RSGB Backpackers series with Paul G1YFC and we achieved great success winning the series and I started doing the 144MHz UKAC series, initially as practice runs for the backpackers then it becomes kind of addictive.

Over December 2016 we tried to rally our local club Hereford Amateur Radio Society into joining us on the bands in the UKAC contests. Take up was encouraging and several members said they would come on the air for the club. Additionally the rules for the UKACs were changed to divide the ‘clubs’ into National and Local. So HARS would be in the section for ‘real’ radio clubs with members only eligible within a 35km radius of a designated central point. During our plans we thought it would be feasible and great if HARS could get into the top 10 of the local club category.

December was busy for me as I had decided to take part in the 50MHz UKAC series along with the 144MHz UKAC series. But to do so I needed a 50MHz beam! So I was busy buying aluminium and building. I finished the main build and tested it literally the evening before the January 50MHz UKAC contest!

144MHz PW QRP.
This is the one I really hope to win and this year we were hoping to repeat our success of 2016. The weather on top of the Black Mountains was evil. Wet and VERY VERY windy all day. It took us 2 hours just to set up the mast and antenna, then we bent my tent poles in the wind so I had to prop up the corner of the tent with my head and shoulders for over 7 hours. However we did well and managed to take the win again.

144MHz UKAC.
On 144MHz I hit the ground running as I used to do a lot of contesting on 144MHz years ago and of course had been active in the UKAC and Backpackers in 2016. After initially entering some 2016 UKACs with the FT-817 I started using the old FT-225RD as it is still the best receiver of the radios I own.
I started 2017 the way I ended 2016, with a winning streak. Competition is fierce on 144MHz but working hard I managed to win all but one of the 12 session, which I am well pleased with.

Myself and Paul G1YFC also took part in the 144MHz Backpackers series. We only managed 3 sessions of the possible 5 due to other commitments, but we managed to win those 3 sessions and retain the trophy we won in 2016.

144MHz Trophy.
I was pleased to be invited to the Isle of Sheppey to join the Blacksheep Contest Group to help operate their open section station in one of the biggest 144MHz contests in the calendar. I have done this in the past with Kevin G1VDF but it’s hard work running a 24 hour station. Blacksheep run a multi mast multi op station which was good fun to see and operate. Despite our best efforts though we were beaten into 2nd place by Parallel Lines CG.

50MHz UKAC.
This was almost a new band for me as we only did a few 50MHz contests in the 90s. I had to build a yagi for the band and literally finished (to a point it was usable) the night before the first contest! I had two inches of snow in that first contest but managed to win, which is a decent achievement being up against G4CLA who is rather good and successful. I lead my section for a while but finally succumbed and was beaten to second place by 65 points only!

432MHz UKAC.
I hadn’t planned to do this band this year but as the club take up was very good I decided I should help out! So I borrowed a beam from Craig M0BUL and started in March. I was much more enthusiastic after winning my first one! I didn’t win the next few but got the hang of the band towards the end of the year. Just enough to scrape winning the section by just THREE points.

70MHz UKAC.
This was another band I hadn’t planned to do but I borrowed a transverter and beam from Matt G8XYJ and started on the band in February, the first time ever on the band for me. I then bought my own Ukranian transverter (which are brilliant for the price) and built my own long yagi twice the length of the borrowed one. This helped me get great results and although I was only able to do 9 of the 12 sessions I managed to win the last few sessions and gain enough points to take the AL section win.
70MHz UKAC AL Section final standings
1296MHz UKAC.
I had no intention at all of taking part on this band but as we went on through the year and were challenging Sheffield for 1st lace overall I decided to try and help us get more points on one of our weaker bands. I had no kit at all but first shared a station with Stuart G3WRA and later borrowed his kit when he wasn’t able to take part. Stuart’s transverter only generates 2W RF so taking part in the AL 10W section was quite hard work. I did manage a 4th place though in December!
I managed 37th place overall from 4 sessions.

Club results.
Hereford Amateur Radio Society had an amazing first year in the local club section of the UKACs. We came 2nd overall and also won the 144MHz and 50MHz bands outright.

RSGB 50MHz UKAC 10th August 2017

Not had much time for posts lately with all the contesting but thought I would do one for this one.

My 50MHz UKAC season started off well in 2017 with a win, and a win in the same section as Pete G4CLA at that. In March I was only beaten into 2nd by a couple of DX MGM modes, so I was quite buoyant about my chances. However as the year has progressed I seem to have dropped in the results. So much so (and in other bands too) I wondered if my feeder was shot so I made a new one but kept it for 144MHz and 70MHz as I had a chance in those bands at least.

However, August has been a good month for me. Apart from not winning my first 144MHz UKAC since October 2016 I have had great results. A 144MHz Backpackers win, 432MHz win, looking good in 70MHz and a very close 50MHz! Only 571 points covered the top 3 claimed scores!

Also Pete ‘CLA was operating as EI/G4CLA and didn’t put an entry in so for now I am artificially sitting top of the pile in 50MHz!

RSGB 70MHz UKAC 16th March 2017

After my first ever go contesting on 70MHz I decided I needed a longer yagi as I could hear stations that couldn’t hear me on the meagre 4W allowed in the 70MHz AL section. That is not a dig at the rules as it makes sense with the licence limit being 160W but it is hard work for sure so a longer yagi is definitely in order I feel. The loaned 4 element has a 2metre boom and stated gain of 6.4dB. It is also constructed using very thin coax for the DK7ZB match which although not much will be bound to have a little loss. My chosen yagi is 5.2m long and has a stated gain of 10.22dB and is made with relatively very low loss coax in the match so I hoped it would help me make it with the usual good  bonus square stations. It was too dark to take a pic of the new yagi this month but the clocks go forward before the next one so I shall be able to get a pic.

On the night either conditions were much better or the new yagi rocks! My QSO count was up a little but more importantly I was able to make it to the stations I couldn’t complete with last month for those valuable bonus squares.

RSGB 80m CC June 2017 SSB contest

Since finishing my 80m inverted vee in March I have been looking unsuccessfully for a closer spacious site big enough to use for erect the dipole as Westhope Common now is now made unwelcoming by a particularly  whinging woman. Very recently my friend Paul G1YFC suggested some land a friend of his owns not 5 miles from my house that would be available. It’s a perfect location for me.

The June 80m CC SSB session happened to be outside a week when I am doing the VHF UKAC events which meant I was able to take part. The last time I managed to take part in March was my first ever time on 80m and just searching and pouncing I came 107th! My lowest contest position ever at the time, by 90 positions! Hopefully out portable with a reasonable antenna I could do better.

Here is Paul and the setup at the new location:
80m inverted vee setup
Despite terrible QRM from a few KHz up I managed to keep a run frequency going and for the most part of the contest managed to average 2 QSOs per minute.

Final QSO count was 142 in the 90 minutes which put me 11th:
June 2017 80m CC SSB entries
After adjudication where I lost 6 QSOs altogether including two where the serial was one out. Seeing as one was 19 received by me and 20 logged, which sound nothing alike I assume this is the out by one issue HF contesters have said about! Annoying. Anyway I ended up joint 13th, which is a lot better than 107th!
