The Arctic King Rocks!

CQ 160 Contest – TF4X #2 in Europe, #6 World !

Yuri, K3BU operated TF4X in the CQ WW 160 meter contest in the Single Operator High Power category.

A solar flare about a week before the contest started caused worry that conditions would be poor.   The band seemed to have recovered nicely, but the Aurora Index stayed high during most of the contest and it became clear that conditions were disturbed.

Iceland is greatly affected by any Auroral disturbance, much more so than neighboring countries and Yuri observed, for example, that my Great Beverage antennas showed almost no directivity during the contest.    I know for a fact that they work very well, but during the weekend it seemed that signals appeared to come from all directions simultaneously.   I understand this may be due to a high arrival angle during disturbed conditions.

Some juicy DX was worked, two KH6 stations for example, it is only recently that the historic first QSO with KH6 was made from my station – this is quite remarkable considering the disturbed conditions.

The raw score is as follows:

1643 QSOs

51 States/Provinces

80 Countries

Total Score = 1,317,729

At present TF4X has the second highest reported score in Europe and is #6 worldwide.   This may of course change as and/or when other stations report their scores, but it is incredibly satisfying to see all my hard work being justified with such superior results.

It was quite illuminating to observe such an experienced operator running my station – at times I feared that my amplifier would literally melt, but it performed to my full satisfaction and there were no equipment/antenna issues whatsoever during the contest.

Yuri wrote in his comment to the 3830 Reflector:


Last minute adventure to the Aurora zone, taking up Thor’s invite.
Being rusty from dormant period, problems with equipment setup,
drivers, but got ready for the start.
Stories about Aurora wipeouts made it a big if.
Thanks to Thor and his magnificent station it ended up being fun and decent
score, even if coming short of beating the Eu record.
The background noise is probably the lowest in the world allowing to
hear lot more of the juicy stuff than working it.
Thanks for wonderful hospitality and station from Thor, TF4M and all the QSOs
and points. Lot of dirty clixing signals and rude behaviour by “CQ pirates”.
Will have more later.

Yuri, TF/K3BU

I used my PERSEUS SDR receiver to record the entire contest 1800-1900kHz.   The recording obviously contains the entire contest effort of TF4X and in addition it contains the contest effort of everyone else heard at my location.

This consumes two hundred GB of data, please contact me if you are interested in specific time periods.

A new chapter in the History of Amateur Radio has been written.

CQ WW 160 – TF4X

Siggi, TF3CW was going to activate TF4X in the CQ WW 160 meter contest, but unforeseen circumstances caused him to cancel.

Yuri, K3BU,  has stepped in and will operate the station in  the  Single Operator High Power category.

I sincerely hope that there will be no sun spots and no Aurora.

This may be the last chance in our life time to enjoy these fantastic conditions on Top Band.

I also hope the activity will reflect this – it would be so very cool if Yuri was able to work All 40 Zones in the contest !

It is interesting to note that I have followed the Tesla Radio Club project for years and several times I have been on the verge of writing to Yuri to invite him to my station !

CQ WorldWide DX Contest 2009 – CW

2009 CQWW CW Contest: 0000 UTC, November 28 through 2359 UTC, November 29.

Three operators arrived from Reykjavik to operate the contest.   Yngvi – TF3Y, Kiddi – TF3KX and Oddur – TF3OO along with a Gourmet Chef who had planned the feast for weeks.

Conditions were rather poor, not a single sun spot during the weekend made conditions on HF rather poor and in addition there was some Auroral activity affecting the lower bands.

Despite this 4525 contacts were made in 48 hours of operation.

You may listen to the activity from TF4X:

The menu was fantastic.   On Friday we had Tom Ka soup with Halibut followed by real-Vanilla ice cream and cake, on Saturday the menu was pigeon breast,  Elk meat with carrots boiled in orange juice and Sunday we had icelandic mountain lamb fille, with baby tomatoes braised in olive oil and maple syrup garnished with fresh Timian.

The Arctic King awed us with the performance –  1270 QSOs were made on Top Band and was only matched by 20M where 1306 QSOs were made using an array of Rhombic antennas.

summary

We used Win-Test contest logging software which performed flawlessly on 5 computers during the entire contest.

We used a feature of the software called Targets Tracking, which showed us real-time graphs on the screen of our progress compared to last year´s effort.   Right from the beginning things were going much better than last year and this was very inspiring throughout the 48 hours.

This graph shows the over-all difference on an hourly basis compared to the effort of 2008.

The Icelandic record in the Multi/Single Category was set by TF3IRA in 1980 at the height of the Sun Spot Cycle.

That record stood at 2,169,760 points.  They made 3004 QSOs and they worked 85 zones and 231 countries to accomplish this.

We beat the 29 year old record handsomely as can be seen in the summary.

It is interesting to note that Yngvi, TF3Y and Kiddi, TF3KX were operators when both records were set.

Highlights of the operation was working a Pile-up of JA stations on 160 meters – this is the first time in history that JA/TF QSOs are made on Top Band during this contest.

KH6 (Hawaii) was worked on 80 meters for the fourth time in TF history that I am aware of.  Prior to this, only Boggi – TF3TF (SK), Yngvi – TF3Y and Gudmi-TF3SG have worked Hawaii on 80 meters.

It was interesting to note some extremely strong poor signals that obliterated parts of the bands along with some strong EU stations that seemed to be completely deaf.  It took me 46 minutes of constant calling to raise one of these stations on the low bands.    It is absolutely necessary to have separate receive antennas for the low bands (160/80) to be able to operate there with any kind of efficiency.

A very successful weekend is behind us and a what a good omen of things to come.

Our SoapBox comment to 3830 was as follows:

Comments:

This was the first CQ WW with TF4X being active. TF4X is a
special call issued to the TF4M station. The latest addition, the
phenomenal Arctic King 160m antenna took us by surprise. Almost as
many QSO’s on 160 as on 20. Numerous new Beverages and zero noise
level on RX. The strength of the station is displayed by low band
performance. First time JA pileup for us from TF on 160m in CQ WW.
Propagation was relatively good as we had little Aurora and definitely
better on the Saturday. According to the raw score the 29 year old M/S
record from TF was broken by 1.1 million points.

TF4X – QSL Manager

Phil,  G3SWH has accepted to be the QSL Manager for TF4X.

My plan of QSLing this call sign only via LOTW met with some grumbling – many DXers, even those using LOTW – still like a traditional paper card for their collections and I understand this perfectly.

Received direct requests will be forwarded to G3SWH.

51st Scandinavian Activity Contest – TF4X

Yngvi, TF3Y operated TF4X in the 51st Scandinavian Activity Contest on CW over the weekend.

sac_cw

The day before the contest, he made around 800 contacts to get acquainted with the new shack.

The score is higher than last year´s winning score in the Single Operator – 20M category.

At this point it looks like TF4X has the highest score in this category – this may of course change as scores get submitted…

I made some recordings of the contest with my Beverage antenna system and the PERSEUS SDR.

You may download a file (147 MB) of the last few minutes of the contest spectrum on 20M CW and play back the spectrum using  WinRad on your own computer.

In order for WinRad to be able to play back recordings made by the PERSEUS software, you will have to download the PERSEUS DLL for WinRad and extract the files to the WinRad directory.

If there is demand, I can provide larger files of the last hour of so on 20M during the contest.

The station performed as expected, except we discovered, when I operated TF4M on 80M,  that the 80M antenna is located too close to the JA rhombic, causing 80M operation to trip the protection circuits on the amplifier on the 20M station.

I operated TF4M on 80M for 45 minutes out of the 24 hours and made 50 contacts.

Without bandpass filters in place, this discovery would have followed the total destruction of the 20M transceiver.  As it were, there was no damage, although the JA rhombic was picking up 50W or so from the 80M antenna….

The first indication of a problem was that I could hear faint noise coming from the 20M operation when listening on the TX antenna – there was no trace of any noise using the Beverage system.

I cascaded two sets of bandpass filters on both 80M and 20M stations, but I could still hear faint interference and then we noticed the faulting of the 20M amplifier when the station was switched to the JA rhombic.

I will solve the problem by relocating the 80M transmit antenna.
