Sporadyk trwał prawie dwie godziny (2014-05-18 10:20 ~ 12:00 UTC), nie licząc wcześniejszej północnej Rosji na OIRT. Niestety ze względu na problemy techniczne początek propagacji nagrał się bez dźwięku, więc sporo ciekawych stacji nie zostało dołączonych do powyższego wideo. Read more / Czytaj dalej →
It is October 28. There is some snow outside and sub-zero temperature. Well, nothing indicates an upcoming Sporadic-E propagation… In the morning, few minutes before 9 UTC, I heard a foreign station on 93.9. I was not sure what’s going on, but after a short investigation I realized that CCIR band is really open to Tunisia and Italy via ionosphere – Es. Definitely rare thing at this time of year. Sporadic-E lasted for about 35 minutes and at ~10:20 everything faded away. Read more / Czytaj dalej →
Since I have modded my XDR-F1HD I can receive also everything above ~60 MHz during Sporadic-E propagations. Studio-transmitter links are typically placed below the CCIR band, somewhere between 50 and 87MHz. They often carry a full MPX signal with stereo and RDS, so these signals are quite easy to identify. Italy has a very high amount of such transmitters. STLs usually have low power but they almost always don’t have a co-channel or adjacent interference during reception – this band is empty here!

Today I noticed some signals from the United Kingdom while I was listening to German stations via aircraft scatter propagation. At first I thought it was just a meteor-scatter, but the signal was too stable and didn’t disappear. BBC from Keelylang Hill came with strong signal for over 30 minutes on 89.3 R2, 91.5 R3, 93.7 R Scotland and 96.0 R4. Of course, other locations from the UK were reaching Poland too, including Rumster Forest, Meldrum, Black Hill, an so on… Read more / Czytaj dalej →
