The first ARRL CW contest when I did not need to spend the entire weekend with antenna building a week before the event! So relaxing.. I used the time for preparations though. I checked the past 30 days SSN numbers to run propagation predicitons at K6TU's site. The software uses by default the predicted SSN figures which seemed to be a bit conservative this time based on the last 30 days historical data. I decided to run a prediction for SSN 130 to see a best case scenario. The reality ended up with even higher numbers than I expected, which did not change much on the outcome, but was helping me to define a worst case sleeping strategy.


Relative to the previous year's contests when the night openings were quite rare and limited to a few hours on one of the two nights only I expected higher activity this time. The predictions have supported the theory plus the high SFI numbers have already indicated that 15/10m bands will be open to attract people working there for the shorter daylight openings. Therefore the QSO rates during the local daytime openings on 20m were even slower than normal. But the nights.. sometimes S7-9 signals with very low noise levels and decent rates.


I made a post contest "prediction" to compare propagation conditions of mine with the two high scoring competitors in Europe (OH8L & 9A2NA). I set the same station configuration (antenna heights/number of elements/output power) for all three predictions to see purely the propagation diversities provided by the station location latitudes.


The prediction files contain 3 x 24 pages for every single hour during the day. I did not want to insert all of them in here; the daytime conditions are quite close among the three, so I picked the timeframe of 22-23UTC to show the real difference.. this is really unfair guys !!!(hi) 

Again; in this simulation there is nothing to do with antenna gain and output power and tower heights, terrain (plains and hills).. it is purely propagation diversity of the same continent!


OH8L @ 22:00 UTC



9A2NA @ 22:00UTC 


HA7GN @ 22:00UTC


A weekend after the contest I spent a few hours to run a "spot analysis" with the related support program of the Reverse Beacon Network. I found it an extremely useful tool for:


- Confirming the signal strength prediction accuracy of the K6TU program thru the actual spots of real CW skimmers.

- One can compare signal strenght of his station to other competitors

- Visual feedback on antenna stack performance per target area (applicable if subject skimmer detection is providing adequate readings with minimum standard deviation)

- Comparing the operating/sleeping strategy with other competitors (assuming the skimmer was able to detect all subject stations in the period of examination)..was it a good idea or not to switch off for a nap at 9:00UTC as such..


The post contest analysis included checking all the North American skimmers being active during the contest weekend. As I did not see the claimed scores of UA5C on the listing at 3830, but quite few spots reported with strong signals; I thought would be wise to involve him in the comparison besides OH8L and 9A2NA. Here below is a few of the lot can be viewed at the RBN site. All of them clearly (sadly) showing that at around 21:30 UTC my signals are declining remarkably relative to 9A2NA and OH8L; just like in the prediction. (The numbers besides the vertical axis represent the signal-to-noise ratio in dB) The program is Beta experimental version; they may fix it later that the legend can be moved out from the graph area.. I did not check how far the database is searchable back in the past, but I was able to run queries for the 2012 ARRL CW just now..

I have run a comparison analysis to see the differences among Hungarian contest stations for benchmarking my signal levels relative to the big boys. HG5D, HG1S and HG7T were entering in all band competition, thus if no spot appears in the timeframe where mine are displayed it could mean they were on a different band. Without extensive analysis it looks that it is not that bad.. (my setup was: KT36XA + 4L longboom monobander + OM2500A)

All in all it was a great contest with rarely experienced good conditions. It gave me the best QSO count ever, even if it was not enough to beat the guys at the top spots. I congratulate to them and will try to catch up to their scores in the coming years. My claimed scores are 234,030 ( 1,345 QSO / 58 multipliers).

CU in the SSB part this weekend.

The chosen category of this year became the Single Op Assissted 20m High. It was my second entry in this category and the first time from my hilltop QTH. Last year I operated form the rental house in Matraszentlaszlo (812m asl) from where I participated in the past seven major contests.
The whole thing started with the preassembly of the KT36XA (M2) sometime in July. The antenna arrived a lot earlier than expected; in about a month after the order placed. The boys went with my wife for a few days summer holiday to the grandma enabling me to free up some time after work to sort the components. The whole house was empty for a few days so I used the place in the living room..
I have limited space on the yard at home so needed to assemble the antenna on a temporary "mast" to see if all components arrived, they fit and work OK, and get a basic understanding of how long it was going to take to reassemble it on the hill. When it was complete I did a quick check with an antenna analyzer and my HF rig. Everything must be fitted as per the factory specs diescribed in the manual giving not much potential for additional adjustments. Regardless of the low testing hights the antenna performed decently promising not much surprises for the later installations. Before dismantling to shipping sizes I carefully marked the corresponding pieces. I had to learn in the past several years that assembling my antennas twice on a decent sunny day takes always less time than doing it only once (saying "it is so trivial..") on a cold windy day up on the hill.
In the meanwhile I did some inspection of the other antenna components; my old 4L monoband Yagi which I built some years ago based on the specs of OH8LQ. Before the KT36 it was my primary contest antenna on 20m. Due to the rental QTH in the past I needed to build and dismantle all my antennas before/after the event. It was very very tiring. Many cases finished just by the start of the contest.. best case only no sleep.
This year was going to be different!!!
The land was cleared off bushes during the summer, and by September the service road and fences have been built.
Then I could finally install the two 20m crankup masts and the security system.
One weekend before the WW DX SSB I put up both antennas as I used to do it - alone. The weather was like in September, never best time to do it. In the neighborhood a group of young people were having a weekend party; cooking a very delicious stew on open fire. My creatures pulled their attention and they kindly invited me for the lunch.
The coming weekends were mostly spent with something unusual: finetuning the station setup and improving ergonomics in the caravan.
In the meantime I always had in mind; it is going smooth..too much smooth.
Then the K9W weekend came..
When rare expeditions are on air I feel the urge to get the first contact asap and then wait a few days to work them again on other bands if possible. The first weekend is always crazy due to the QRMers and the high traffic, but it is difficult to stay away, if I see on the cluster they are out there. I sweared so many times I will rather be with my family instead.. My home QTH antenna is always half way erected to avoid trouble at high winds. When expeditions are on air I used to lift it up to its total height. This was taking place November 3rd; while working with the winch by a bad move I managed to get my left hand biceps completely torn off. That time it was not very painful actually, till I got to see the doctor who said that the thing needs a surgery and an arm fixing for 4-6 weeks. Ooh, Yees..this is what I was waiting for.. Current lifestyle does not let much of a rest with the two small kids (3,5 years and 6 months old) and high season at work 80km away from home..
For a moment I gave up the plans to go for the contest, too. But, that took for a moment only. A few days experience with my "wood-hand" in our busy life gave me the confidence that it will work out..
The WW weekend was extremely painful though. Ergonomics were not ready for my one-handed mode in the 44 hours of operation. I was not able to sleep Friday night before the contest and jumped into the first 27 hours with headache..again, but that seems to me normal by now after all those previous contests. I always get so excited the night before that could not get any sleep most of the cases.
My running rates were not going beyond 3 QSO/min or occassionally to 4 QSO/min due to my temporary limited abilities.
Other than the internet connection on Sunday everything was working smoothly. I use RBN since a while when entering assissted mode. Having most of the multipliers collected on Saturday did not feel the urge to go for additional mults on Sunday when there was no 3G connection for the entire day. The final score seemed to be degraded by approximately 50k points due to the missed potential mults. Improving the 3G signal strenght by an external logperiodic will be a task for next year. Or maybe a local SDR and a CW skimmer.. I will see.
The two large indexable aerials; with the simultaneous multiple direction beaming towards Asia and North America plus the perfect location were paying off though. The final claimed score is 882,000 points with 2,405 contacts, 37 zones, and 140 countries, hoping to be enough for a World 6th, Europe 3rd and a new Hungarian record.
This is the contest I can hardly wait to begin every year and it takes only for a weekend. This is also the one of with the winter arrives and HAM radio goes to standby a bit till the end of February when the next challenge is due; ARRL International DX CW. CU in the bands!
Till that it is time to be with my lovely ones who let me live this crazy hobby.
