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!
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.
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.
Thank you to all paricipants and those who had patience to complete some QSOs!
During the morning I was able to monitor GB3FM in IO91OF on 1297.050 MHz and G8MBU in IO90IR on 1296.800 MHz. Now in the afternoon F5ZCS in IN87PT on 1296.959 MHz came out of the noise with a strong signal of 549 with fast QSB. It is my 53rd beacon on 23 cm. The weather here in Mainz doesn´t look like tropo: 8/8 cloudy and wind at 40 km/h.
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!
Everything 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.
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.
The 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.
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.
QSOs 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.
Today PI9CAM´s QSL for the first Satellite Bounce QSO via an unmanned spacecraft done by radio amateurs arrived by mail. As we know, there have been previous commercial attempts for Satellite Bounce in the early 60s using ECHO 1 and ECHO 2 which were inflated balloons with diameters of 30 and 41 m. The initial orbits were at heights of 1500 km and 1200 km.
The theoretical radar cross section (RCS) of ECHO 1 was 700 m², but measurements by military radar stations resulted in 900 to 1000 m² in the beginning. Later, the satellite deformed and shrunk. OKEAN-O, the one we used, has a radar cross section of 18 to 20 m² but is in a much lower orbit at a height of 650 km. This leads to quite similar unit power budgets, regardless the difference in size,
Enjoy the movie “The Big Bounce” about our predecessors 55 years ago!
