November 2015: extreme autumnal tropo

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!

October 2015: UKR, FIN, HOL ducting

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.

October 2015: D, HRV, SVN ducting

I haven’t collected my thoughts yet, since the extreme tropo propagation from the United Kingdom in October and meanwhile a favourable weather brought the distant radio reception once again. I was travelling back home in a bus on October 23 and I was listening remotely to a radio at my QTH. Local conditions on the CCIR band were, saying the least, terrible. All nearby locations like Poznań or Wrocław/Ślęża were continuously fading down into noise.

Anyway, I’ve been notified about excellent conditions on the 144 MHz band that day, so I continued scanning. For the first time ever, a QSO was made between Spain and Poland via tropo at distance over 1900km. My location was a little too east of the ducting area, however I also found some unusual activity on the 87.5-108MHz band. At one point, I noticed that I’m listening to Ochsenkopf @ 621km instead of Zet Gold from Poznań on 99.4. The signal level was quite unstable, but it was definitely not an aircraft scatter. From time to time the signal was reaching RDS level on both 99.4 Bayern 3 and 90.7 Bayern 1, with a new local PS Bayern1N instead of previously used BR_1_FRA.

October 2015: extreme tropo from UK in Poland

This year, the weather at the beginning of October was extraordinary. A massive high pressure system has established itself over the greater part of Europe. It was very warm and the sky was totally clear. I was pretty sure that something special will happen… now or never! All propagation forecasts were very promising at first. However, the ducting area was reduced after each update, at least for Poland. Nevertheless, tropo results were excellent – BBC reception lasted for three days!!

Aurora FM-DX 20.12.2015

Another auroral propagation appeared on December 20. I don’t really remember, but it was probably third or even fourth big show of such nature this year. Aurora happens usually during the months around the equinoxes, so nice to observe it in late December. In the afternoon I noticed some distorted stations fading in and out. Stronger signals flooded entire CCIR band around 16 UTC. I quickly identified SR P1 on 89,4 with their “bell” jingle and many other frequencies of P1. Norway was also here with 88.7 NRK P1 (//web). The signal levels have increased even more, so I decided to grab a camera and try to take a photo.

Testy nadajnika 105,4 w Sieradzu

W piątek – 11 grudnia 2015r. – w godzinach popołudniowych odbyły się testy nadajnika 105,4 MHz. Odbiór nośnej z pilotem stereo i RDS był możliwy w okolicach Płocka z anteną w polaryzacji pionowej ustawioną w kierunku Sieradza w odległości ok. 130km. Podnośna RDS zawierała PS i RT złożony z samych kresek, PTY Info, zsynchronizowany zegar (CT) oraz kod PI FFFF.

Według dokumentu KRRiT emisja nowego nadajnika ma się odbywać z Komina PEC przy ul. Zachodniej 2 w Sieradzu z mocą 2kW ERP. Decyzja rozszerzająca koncesję radia Tok FM została wydana 10 listopada.

Sierpień 2015: Tropo UKF AUT/HNG

Kolejne letnie tropo wystąpiło w dość szczególnym dniu – był to wieczór i noc z 27 na 28 sierpnia 2015 roku. Dokładnie 5 lat temu, 27 sierpnia 2010 roku, na moim maszcie pojawiła się nowa antena Körner 19.3. Układ wyżów nad Europą przyniósł tym razem tropo z bardzo ciekawego i rzadko występującego kierunku jakim niewątpliwie jest Austria i Węgry. Większość dnia byłem poza domem, a gdy wróciłem wieczorem okazało się, że na paśmie UKF znajdują się dość stabilne sygnały stacji radiowych z Austrii.
