VHF/UHF/SHF Contest May 2017 – Record breaking again!

May 7th, 2017

After the unexpected good result in March on 13 cm, I had a special focus on this band in May contest. Last year I marked my new record in the number of stations worked on 23 cm, this year I improved the new record from March in worked stations on 13 cm. Particularly in the last hour I had the ambition to log at least 40 Stations. So I had QSO #40 in the last 5 minutes with Detlef, DJ3AK, in JO52GJ, 322 km, using aircraft reflections on planes just 50 km from my location, elevating the dish up to 10°: Power Aircraft Scatter 😉

QSOs on 13 cm

With QSOs to Poland, Hungary and Belgium three new countries could be added to the 13 cm list. HG7F (817 km) is my new aircraft scatter ODX. Also some new grid squares could be logged.

And again: After the contest is before the contest! A lot of ideas are in my mind, what has to be improved for the next competitions!

Compilation of European VHF/UHF/SHF Activity Contests

January 16th, 2017

Most of the VHF/UHF/SHF enthusiasts will know very well about the activity contests in Europe. But there is a number of just interested radio amateurs, who would like try on these bands. They will find dates and times as well as links to the rules of certain contests in my list. If there are any monthly activity contests, not listed, please let me know.

Surprise, Surprise!

January 12th, 2017

When looking for the annual results of the Italian Activity Contest 2016 on 1296 MHz yesterday, I was really surprised, to be the winner. I haven´t expexted this, as Giorgio, IK3GHY, had a higher score in total all the time. But as he won in 2015, he was out of competition in 2016. I have to respect his success and congratulations for your extraordinary score, Giorgio!

But anyway, it was great fun to work the italian lads every 3rd Tuesday in month. Hopefully, there will be enough time to be QRV in the 2017 events. I am also looking forward to go to Italy in October, meeting friends in Venice and at the Alpe Adria meeting near Udine.

Steve, IU1EAF, will be the contest manager in 2017 and the rules have changed too (english version online now). Thank you to Alfredo, IK2FTB, for all the work in the past year.

 

November IAC/NAC/UKAC on 23 cm

November 17th, 2016

I have been very short in time for this activity evening, but managed to work 10 Stations within one hour. The first three were the three Johns from UK: G4BAO, G3XDY and G4ZTR.

IARU Region 1 UHF/SHF Contest ist over

October 2nd, 2016

Despite a late start and easy going operation, at least 63 QSOs filled the log for the 23 cm band. HA5KDQ from Budapest (JN97LN) became my new contest-ODX with 829 km. As can be seen in the map, the eastern directions are my favourite ones.

July-Results of Italian Activity Contest published

September 8th, 2016

It´s nice to see me as #2 in IAC. To meet the lads from Italy on 23 cm every 3rd Tuesday in month is always big fun. Unfortunately I missed the August event due to my dismantled rotor. Instead I met Giorgio, IK3GHY, at the EME Conference in Venice. Also big fun to see his new amplifier for 23 cm there, wow!

2016-09-08-21_40_02-2016_iac_annuale_1k3-4-pdf-adobe-acrobat-reader-dcEverything is up and running again. Jacek of Spid in Poland gratefully did a great job in fixing my rotor. So I expect to be present in the September-IAC.

VHF/UHF/SHF Contest May 2016 – Record breaking!

May 8th, 2016

And another Contest is over. Again I learned a lot and I am happy with the results: With a count of 82 QSOs I broke my personal record in claimed QSOs in a 23 cm contest. Since October1990 the number has been as high as 78 QSOs.

RA-Maps JN49CV89KF 2016-05-08 14-32The claimed score is a little more than 30.000 points and a new personal record as well. The 82 Stations, worked on 1296 MHz, are from 12 DXCC countries and located in 41 different grid squares. Countries worked were 40 x DL, 1 x F, 3 x G, 2 x HB9, 1 x HA, 5 x I, 6 x OE, 14 x OK, 1 x OM, 1 x ON, 5 x PA and 3 x S5.  In most of the QSOs aircraft scatter was an important factor. 35 contacts were done in CW. ODX, as usual, was HG7F over 817 km, still my ODX via AS. Nice was to work 3 OE5-stations around local midnight within 10 minutes: OE5VRL/5, OE5JFL and OE5RBO.

 

VHF/UHF/SHF Contest March 2016

March 6th, 2016

The contest is over and there are new ideas in my mind, how to improve for the next one. Even though I am using a homebrew KST-client beside the browser based one, arranging skeds in the ON4KST chat is still the bottleneck in operating the contest. I fear, many requests will disappear from the screens of many operators, before they can take notice. No reason to argue for me, instead I will continue working on my KST-client projekt.

RA-Maps jn49cv 2016-03-06 1296QSOs on 1296 MHz

I had much fun in using Aircraft Scatter on 1296 MHz for most of the 58 QSOs, logged on this band. The average was 372 km/QSO and I worked 37 grids in 12 countries. And again HG7F became the ODX with a distance of 817 km. Weather was very bad and many of the contest teams weren´t able to go to their usual locations. So this time only one Station could be worked from JN99, compared to seven in July 2015.

VHF/UHF/SHF Contest July 2015

July 18th, 2015

When having a look on the claimed scores list, published today, I was really surprised by my preliminary result in the category 23 cm single operator. I did not expect at all to be No. 1.

It had been very hot that weekend and the activity in the ON4KST Microwave chat was extremly high. So I slowed down, made only little use of the chat and tried to find calling stations on the 23 cm band. There were a lot of signals from the east and when going to bed at midnight I counted 29 QSOs with an average of 524 km/QSO. Top DXCC count was OK (11) followed by DL (5), OM (4) and G (3).

QSOs on 23 cm. Saturday in red and Sunday in green

On Sunday morning I continued, but it was still very hot and not much fun. When the temperature in my shack exceeded 40°C at around 10:00 UTC, I decided to go QRT.

Finally I logged 45 Stations from 12 DXCCs in 27 squares with an average of 483 km per QSO.  17 stations were worked in CW, the rest (28) in SSB. 10 QSOs had a QRB > 700 km (7 x JN99) and the ODX was HG7F with 817 km. The total time of operation was less than 15 hours.

 

IARU-Region-1 UHF/Microwaves Contest 2014

October 5th, 2014

After my complainments about using the ON4KST chat in March Contest and the response I received from Claus, OZ1FDH, and Kjeld, OZ1FF, recommending the KST2ME tool, I added my homebrew prototype of a selective ON4KST client extension to my station control software. It communicates via telnet with the server. While working satisfactorily under normal circumstances, it was a desaster under contest load. When the software didn´t crash, it at least slowed down, by computing hundreds of posts in shortest time. Between 300 and 400 users have been logged to the microwave chat during contest time. During the first contest hours I tried to solve the problems with certain bug fixes, resulting in a huge loss of contest time. So I had to return to the classic style in using the web client of the chat.

QSOs on 23 cm

In total I logged 73 QSOs on 23 cm to 12 DXCC countries, spread over 39 grid squares (results). ODX was HG7F over 817 km. The use of the AirScout software, written by Frank, DL2ALF, has been essential. Most of the QSOs have been completed by assistance of aircraft scatter.

A nice example is the one with DJ5BV in JO30KI. The distance isn´t really far enough to do it via aircraft sctatter, but it seems, both antennas were pointing west and that resulted in effects of aircraft backscatter with significant dopplershifted reflections.
