Then follow the lecture: EME during 2012 (OK1CA, OK1DFC, OK1VAO), measurement noise (OK1UGA) TRV 1296 MHz (OK1VUM) Remote control for HF and VHF workplace (OK1DIX, OK7GU), SSPA 10 GHz band for! (OK2AQ), microwave beacons (OK1AIY). After the lecture, some leave back home. Those who remain continue discussions late into the evening, very pleasant.

Beacon OK0EW 24GHz off

Tuesday, October 9th, 2012

Today was shut beacon OK0EW to 24GHz. For a long time there was a problem with ocilátorem and then goes in for repair. The assumption is that it will be operational in the spring of 2013.

UHF Contest 2012

Monday, October 8th, 2012

overall result The first weekend in October the UHF contest. As indicated weather forecasts, so we did not expect anything funny. I went out on a forest on Friday to check the work and do some repairs. In the mountains it is quite cold. On Saturday came a couple of club members take off before winter dish. He came and Pepa OK1ES who through adversity wind had built an antenna for 6 cm band and 24GHz. Before the race we managed to take down an antenna system for dvoumetr. I went to prepare for the race which I assumed that nothing much. After the start of the race, the other began to return home, and we Pepa we stayed on the hill. On Saturday approached the queue and it started raining and did not stop all night. On Sunday morning the rain had stopped but still windy. Despite the bad weather has managed several nice connection. UHF Contest 2012 The conditions were so variable that the station under normal conditions do was read the problem and after a while there were extreme forces. We were able to make connections with TM2W in JN37, which was Grupa OK2KKW. And as the icing on the cake in the last minute of the race I4XCC as ODX at the plant 740 km. I appreciate Claudio, a few minutes before the end of the race properly assess the weather situation between us and asked for a test. RS low, but in the right place so the connection is successful. At the end of the race it ceased raining and the clouds are bursting. after UHF contest Preliminary results on VKVZavody . And the IARU contests .

start of September 2012

Saturday, September 8th, 2012

tower OK1JKT (10GHz) Since the last article is always something to do on 3cm band are still some RS and now increasing to tropo conditions. The first weekend in September Day Records on 2m band as OL4A, a day before some training and the race went quite well. It was done about 920 connections are solid but the average number of end points do not know, I do not carry any data. Later will be more on OL4A . Next week is already marked tropo conditions, although mainly to the west of us. Still do thrive in Thursday, 09.06 conjunction with Maurice F6DKW 834 km and 904 km G4EAT John. This day in addition to the connection can be heard pretty lighthouse HB9BBD / p and mainly beacon GB3SCX in a square IO80uu a distance of 1107 km! After trying conjunction with Ralph G4ALY in IO70, but unfortunately there was not passing it. Today Saturday, 09.08 we have another chance, probably in the evening and on Sunday morning / afternoon is prerequisite to further raise the tropo condx.

Continue ... Saturday condx on 3cm continue, I'm conjunction with Nick G4KUX in IO94bp 1128 km. However, activity is still very weak.

Condx continue ...

Wednesday, August 22nd, 2012

after sunrise In the last days of good conditions continue, no longer only RS but i tropics. However, activity in the 3 cm band is not large, the majority of stations that actually pay DX connections and fro someone else.
At the end of last week to make good tropo podmímky, although not much but lighthouses around 500 km playing incredibly hard. Nevertheless, the connection is minimal. At the end of the weekend and especially at the beginning of this week coming RS, coming from the west front which is a lot scatters. On Monday, the already unbearable heat down and look at the radar I drove on the forest. Already on arrival find that something is wrong. Doors do not open the parcel and so'm parked across from the fact that I look at it later (after cooling in the morning, everything works as it should). After turning on the device and open all the possible holes in the cell is slowly becoming obyvytelnou although the heat is oppressive. Looking at the data from the weather station to the hotel is the temperature at a height of 911 m asl 33.2 ° C.
This heat is reflected, for example, at the lighthouse OK0ET in Prague instead of the usual frequency is 10,368.898 10,368.913! During this afternoon I twice overheated equipment that I had to turn off and wait until it cools down, it just did not hang already oscillator.
* Not only amateurs use this weather, you can see some gliders, sport aircraft, gliders and wings. But the conditions immediately after switching to another konektuji ON4KST to chat and see that they agree F6DKW Maurice and Rene DL0AR. It is evident that the scatter is great, but somehow can not find it. I tune to 10368.120 MHz and after a while I hear Maurice and soon again. After a brief consultation deserts CQ in the direction from which it was heard and the connection is done in no time. Then it is not a problem for Rene Maurice find a link to do. Rene was JN69 and Maurice F6DKW is a square with the serial number 110. Maurice My congrats!
RS continues all day and so does the QSO in F, DL, OZ, SM, HB9, I ... on the second day on Tuesday as RS, but I have some responsibilities at home and just watch the DXClusteru.

End July weekend and 1st August 2012

Monday, August 6th, 2012

The end of July is still marked by rain-scatter. Each day, the conditions in all directions and so not worth calculating individual connections and listening lighthouses in 3 cm band. The weekend RS conditions continue. On Saturday, again at full power station in the south such as Expedition Max IN3/DK1MAX (JN56) and Zlatko 9A2SB with 200 mW at full strength. Sunday was expected to continue shipping OE9/DK1MAX (JN46). Max appeared but unfortunately for me did a few DL stations and me no signal, just at the time there was no use RS. When Max finished and shifted to HB0 switched on and I have to move home. In the week between 6 and 12 August will probably not be QRV.

19th - 22nd April 2012

Tuesday, July 24th, 2012

Very promising weather drove me up the hill on Thursday. Lighthouse IQ6AN played both their lives station from the south at full strength but somehow I could not get through. After several tests with DL7QY and I4XCC I talked with Rene DL6NAA the connection and it was immediately clear that something is wrong. After finding that the relay does not switch to the waveguide paths TX, transvertor went down. On that occasion, I modified cables and relay repaired and in the evening I was ready. In the evening I made two test connection but RS DX were long gone. On Friday, RS Conditions of repeated nova although not as much as the previous day, but everything works back to full satisfaction. Among other connection I have worked with Zlatko 9A2SB who ingested only 200 mW and yet here he played 59S. On Saturday, RS shifted more to the south and southeast, and so I was just listening.

14-15th July 2012

Monday, July 16th, 2012

On Saturday I finally dug on the forest. Pretty nice conditions when it lifted the tropics, a few links to the west around 500km. Rain scatters relatively high although very low. On Sunday I drove operating assets 13 connections and 11 multipliers. Very nice, but a few more were combined with Gabi HA8MV / p (KN06ht) when I was crazy, despite interference from a nearby TV transmitter heard from Gabi three signals RS 53s, 419 tropical and very nicely over 559 aircraft.
