August 2016 started with a cold and rainy weather, which continued for more than half of the month. It had some advantages though, as the radio band was clear of tropo signals during peak of the Perseids. Thankfully, the end of August was much more exciting and brought a superior tropospheric ducting propagation conditions. It started with distant Germany, Denmark, Sweden, AustriaFrance and then, after three days, moved more into central Europe, to a completely unexpected set of countries: Slovenia, CroatiaBosnia and Herzegovina and… ITALY!

Long range tropospheric ducting was lasting this time for 6 days – starting from August 23 until Sunday, August 28. Because of a very high amount of notable DX receptions, this article describes only the first three days of this awesome tropo opening. Read more / Czytaj dalej →

The weather in first days of summer brought a widespread high pressure system that has settled down over Eastern and Central Europe. Very good tropospheric conditions were forecasted between Germany, Switzerland, Czech Republic and partially Poland. 

In the evening on June 23, I quickly checked the signals before sleep. There was nothing interesting on the 87.5-108 MHz band… except one low modulated station on 107.3. I have already received hr4 from Germany on this frequency twice before, but with weak signal levels. I was quite busy, so I kept the 107.3 tuned for any upcoming identification. In a moment I saw a PI code: D704. Well, that was odd, because I thought that hr4 carries a different PI code. And I was right, shortly I heard an ID – SWR4 verkehr! So, this time I got Raichberg @ 898 km on this frequency. Read more / Czytaj dalej →

I am pleased to announce that the long-awaited 1.0 version of XDR-GTK has just been released. As usually, XDR-I2C upgrade to the latest version (2016-04-20) is also required.

The main window contains new interference detectors: CCI (co-channel) and ACI (adjacent channel) which make the antenna pointing easier for the best signal to interference and noise ratio. Read more / Czytaj dalej →

The beginning of December brought an unexpected tropospheric propagation. The weather was influenced by high pressure and it was rainy. In the evening on December 2nd, 2015 I noticed some distant signals. When I checked my tuner remotely, FM4 from Salzburg was already at stereo + RDS level. In just a hour I also heard Wendelstein, Hornisgrinde, Bregenz, Grünten, Säntis and the furthest location – Rigi @ 1015km, which I logged for the first time. Read more / Czytaj dalej →

The enhanced propagation conditions continued from late October to the beginning of November. All upcoming forecasts were very encouraging and I have experienced the most extreme tropospheric ducting propagations from Norway, Sweden, Denmark and Germany in terms of signal strength. Tropo was also very strong on microwave frequencies and I logged 300+km 5GHz WiFi networks, including Czech Republic again! Finally, I heard a very long awaited location – Kyiv, my new ODX from Ukraine! Read more / Czytaj dalej →

Another tropospheric ducting propagation this month developed on October 30 and 31 night. This time I didn’t expect anything special at all. I was busy all evening and I was about to sleep, however I saw the tropo forecasts. Both of them directed my attention to Ukraine, which is mostly unexplored country in terms of a radio reception for us – DXers in Poland. There are two main reasons. Firstly, propagation from east and south-east occurs the least frequently. Secondly, a majority of stations use low transmit power and poor broadcasting locations.
