 Yngvi, TF3Y piloted TF4X in the CQ WorldWide SSB Contest in the Single-Operator, Single-Band, High Power Category.

TFM 4398 DxO
TF3Y@TF4X

When the dust settled, the score was as follows:

3124 QSOs

93 Countries

25 CQ Zones

for a final score of 571,710 points.

Due to the recent sun spot minimum more or less since 2003,  there has been little activity on 10-Meters and almost no activity from my station.

Yngvi´s score was 5 times higher than last year´s top score in this category from Europe and his QSO total is similar to what Multi-Operator stations in the US  and top stations in the Caribbean accomplished this year.  

KC1XX had 3061 QSO’s, the K3LR super station had 3033 QSOs on 10 meters and W2GD made 3356 contacts on 10 meters from P40W in Aruba to give a few examples from the contest this past weekend.  TF4X´s 3124 QSOs compares very favorably considering the difference in propagation in the frigid north to what stations further south experience.

Most of the contest was recorded, both the audio and the 10 Meter Band spectrum using a Perseus SDR.

Here is a recording made on Sunday:

Yngvi wrote in his Soap Box comments : 

“Had a great time. Ten showed a bit of life but still big room for
improvement, e.g. no JA’s. Being able to transmit to many Rhombics
while selecting others for reception is a big plus. The performance
of the station was excellent apart from a 40 min. electricity outage
due to a fault at the power company. Thor’s station keeps improving
year by year. Due to poor conditions in the past few years there has
not been much activity from the station on ten meters. We now have
proof that the Rhombics do a great job on that band as well. “

It’s not all work and no play, we also take time to enjoy good food and wine, it has become a tradition that my visitors contribute to the food over the weekend in exchange for the use of the station.

On Thursday I put a leg of Mountain Lamb into the oven to slow cook for 24 hours at 60°C – it turned out absolutely magnificent – I will be using this method often in the future.

Yngvi generously brought a very nice aged T-Bone steak 5cm thick which I prepared in my gourmet kitchen for Saturday’s evening meal.

Perfect ! – details of cooking method provided on request. :-)

TFM 4424 DxO
The best T-Bone in the Arctic.

Sunday morning we had Spinach Shakshukah and in the evening slow cooked chicken…all dishes washed down with conservative amounts of fine wines.

Robert, S53R has been active from Khartoum, Sudan.  

I had a rare SSB contact with him on 20 meters moments before he shut down.

As you can hear the competion was quite intense.

Later I had a QSO with him on 10m CW, but no recording was made.  

This is our QSO on 12m CW

Jouko, OH1RX who was on a Salmon fishing trip visited my area with his group and operated TF4X in the IARU contest.

Conditions were rather poor, but this was to be expected at this time of the year.

Antennas and equipment performed without incidents.

Jouko commented to the contest organizers:

“Great experience to work agn from ultima thule at Thors fantastic  station. Bands are never kind to the ops above 64N, but his time it was a real uphill. Nevertheless, I hope you enjoyed couple of low band mults from TF!

CUL agn de Jouko OH1RX”

It was an honour to have such an accomplished contester operate my station.

I hope to see OH1RX again perhaps for a serious effort one day.

I am taking the opportunity while the weather is bad to work inside the shack.

New cables have been routed into the equipment room and a 19″ equipment rack installed for the Harris amplifiers.

Two cables were installed for future use with the ends coming out of the ground in strategic places.

Hopefully I will not need to route more cables into the shack.

Operating position “C” is now fully operational – I tested the Harris RT1446/RF-350K with the 1KW amplifier this afternoon and there seem to be no problems.

It only remains to connect and test operating position “D” and then the station will be fully functional.

I would be interested in comments on the quality of my signals.

One operating position is fully functional.   The shack has 4 operating positions and each position can choose any available transmit antenna through a 100 kW Strip Line Matrix Switch remotely controlled.

The remaining tasks are to install panels at each operating position to plug in bandpass filters, install wiring for remote antenna switches and power combiners, install computers at positions C and D, wire up PTT control to the Strip Line Matrix switch (to prevent the possibility of hot-switching) and build an indicator panel for the switch.

I will now concentrate on the farm work until autumn before continuing with the project.

One operating position is ready – position B which has the control unit for all antennas.   Some work remains, dressing cables, installing computers and building brackets for Bandpass Filters etc.

 

During my Arctic Diamonds presentation on the CCF/OHDXF Ferry Cruise in January, – Tonno, ES5TV asked me whether I had any ”normal”  antennas to compare my rhombics with.   

My answer was a tongue-in-cheek reply to the effect that since I had unlimited space at my disposal, I wasn´t interested in limited space antennas.

A fellow Rhombic owner who indeed has such a comparison antenna sent me the following audio files which demonstrate the difference between the reception of  ”normal ”  antennas and Rhombics.

The first audio file is of TL0A an Amateur Radio Station located  in the Central African Republic, recorded using a huge Log Periodic at 30 meters height.  

Most Radio Amateurs would kill to have such an antenna ! :-)

The second recording is made 3 minutes later, from the same location, but this time using a  Rhombic antenna to receive TL0A.

A visual comparison of the two files  says more than a thousand words:

TL0A on LP antenna

TL0A received with a Rhombic

My Rhombic colleague commented as follows:

”… you will hear what a 30 meter high 6.5 dB gain antenna sounds like with a very wide radiation pattern. It is ideal to pick up all the noise and electrical storms in the equatorial noise zone.

The other recording is 3 minutes later,  with a Rhombic with 20 dB gain, 10 meters high, low take off angle- and a beam width of just 10 degrees. It is not so much that the signal is that much stronger, it is that the noise is that much less. Note the ease with which it is possible to pick up and follow S1 stations that are very weak.

A Rhombic is not just about the gain, it is much more about the noise which you Dont Get…”

 

I rest my case.

The first QSOs from the new DXCC entity of East Timor, were made by Ross, 4W6UN and a few days later I got my licence as 4W6MM.  I started calling CQ on the 10M band and it took a while until the first station was in the log.

JA7JVY was the first station in the log, followed by JG5IAA and  N6DQ, who was the first U.S. station in the log.

I was using an Icom IC706MKIIG with a random wire at the time.

These contacts represent  the first QSOs made from East Timor after decades of silence.

I made 42,419 QSOs as 4W6MM.

The first recording was made on the 16th of March, 2000.
