Last weekend was held A1 Contest on 2m band. We left the factory assembly tadiční OK1DTC, OK1DSX, OK1ES, and OK1HGM OK1JKT brand OL4A. Quite unpleasant weather, fog, and fairly strong winds. On Sunday around noon, after all, the sun turned out from the clouds, and so I did just embarked on a pole to remove the device for 3 cm band. After about 10 years already it says about upgrading and maintenance. A1 contest, we ended up with about 515 QSOs and just over 180 000 points, ODX LA0BY 1062 km.

1st weekend September 2011

Friday, September 2nd, 2011

On the hill I went out on Thursday. Unfortunately, all the RS in the west are so far away and make connections between other French stations. Yet there are more MS points on the south, after consultation with Claudio I4XCC we found two usable scatter, but the signals are relatively weak. At about 15.30 UT I see on radar images from the massive storm over southern Austria at about JN77pa. The challenge comes with a very nice signal Gabi HA8MV / p and Zlatko 9A2SB report which gives me +40 59s! Once again, I do QSO with Claudio, who offered to Gabi that he moves into a square JN64ha. Gabi makes the connection so it is increasing more square, then I do have a connection with Claudio. Gradually scatterpoint is shifting to the east and weakening hear stations. On Friday morning I still down to do the necessary work, but I am back on the hill.
Around noon, near featureless MS from the southwest. Is interesting to look at the SDR radio in HB9, there is strong HB9AMH hear. I try to test the RS and listen via the SDR unfortunately I can not hear the audio but I see her on the monitor signal, very weak, even after dosměrování ... yet the MS moves to the east and begin to be heard and beacons DB0ANU DB0FGB, I search for another but nothing.
Again formed a nice working with MS 9A5MT, 9A2SB, and before that 9A1CRJ tropo DC8EC and DL7QY
03.09.2011 In the morning calm of a very powerful beacon výchdu SR6XHC and OK0EA. On Saturday přjíždí other members of the club and prepare for the race, "Records Day" on 2 meters. You guys do some exploring around the measurement and interference that comes from strong TV signal transmitter, a bit of grilling sausages. And we can start the race ...
The end of the race is over so briefly on the results. Over 900 QSOs in about 340,000 points during an average 372 km / QSO ODX TK1E JN42lm and 958 km.
The 3 cm although some MS are, but I'm going home ...

Field Day 2010

Monday, July 5th, 2010

The first weekend in July we participated in field day under the brand OL4A. Some members of the club OK1KIM since Thursday were on Forest dodělávat antenna for two meters. Because I have a grandson at home for the holidays so I could go on a Friday evening Lesna. On Saturday, finishing the last antennas, computers and other small items. At the end of the race we went on bands 2m, 70cm, 23cm, 6 cm and 3 cm. 24 GHz as well but unfortunately did not go out any power. Just mention the 3 cm band, the other certainly comment on their own. Before the race I made a picture from the internet as it is with MS and tropo conditions. Before the race I heard the band several Western as it is hot and nice, there will be no conditions to be little connection etc. It amused me extremely, and I think that eventually went out who was satisfied with microwaves.
circulation On Sunday the race was held at Forest European Cup cycle and also us Zdenek OK1AR visited with the family.

So finally the raw data at 10 GHz: 86 connections that gave a little over 29,000 points with a diameter of 340 km / QSO ODX G3LQR JO02QF and 858 km. Later results will be on VHF races .

MMC 2009

Monday, November 9th, 2009

On Saturday I went to the forest on the Marconi Memorial Contest, I just pulled over Jindřišská began fog and thick ice everywhere. The closer to the goal, the ice appeared stronger and more broken branches and trees. Hundreds of birch did not withstand the weight of ice and broke in half like matchsticks. Here and there it took a spruce or pine. Already at this point of view it was clear what image awaits us on the hill.
MMC 2009 - OL4A MMC 2009 - OL4A MMC 2009 - OL4A Therefore had to repair and modify what was possible. We have installed at least one antenna, the quadruplet were only two lower twin antennas and lower dipole was rotated by 90 degrees. And so we started the race late and has been catching up.
MMC 2009 - OL4A Here are the raw data at the end of the race OL4A JO60rn.

VHF Contest 2009

Tuesday, September 8th, 2009

The first weekend in September, I participated along with other VHF contest. Before the contest on Thursday, I was QRV on the 3 cm band. I made ​​two RS connection to Denmark (OZ2LD, OZ3ZW) and two connections to Croatia (9A2SB, 9A1CAL) via tropo. On Friday, began arriving club members and so began dodělávat antenna and so on. The race took place on the whole calm, except for problems with interference from a few stations that produced strong noise and splatery around the band. Made with less than 900 QSOs, preliminary results will be as usual on a server VKVZávody .
