NDR, WDR, SWR & hr tropo

I’ve been watching live propagation maps for few days. The upcoming tropo was staying somewhere between UK/Ireland and Austria, without any signs at my QTH. Finally on 15th November interesting conditions reached Poland, too. In the evening, stations appeared from Teutoburger Wald, Kreuzberg and Hoher Meißner, but with poor signal levels. Well… something is always better than no reception at all! ;-) The next day was much better  – I got Ederkopf, Ahrweiler (!) and Olsberg in the morning. As usually when the tropo starts I must go out. Anyway, remote tuner controlling via internet is really a brilliant thing.

September 2012: Long-range FM & OIRT ducting

Autumn is well known as a perfect season for tropospheric ducting. First notable long-path ducting occurred this year on September 7, but it was just a short propagation. This time, good tropo conditions lasted much longer. Everything started in the evening on October 18 with strong tropo from Lithuania and Belarus. I also got some stations on OIRT band (66 – 74MHz) including Babrujsk (~650km, 73.01 stereo O=5-). Actually I don’t have any OIRT-dedicated antenna and my all receptions were made using Körner 19.3. Stations from Vilnius reached RDS & clear stereo signal (98.3, 102.6, 106.8). Although the distances were not so great, I have received some stations for the first time.

Es STLs of 2012

Studio-transmitter links are typically placed below the CCIR band – somewhere between 50 and 87 MHz. 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 are low power but they almost always don’t have a co-channel or adjacent interference during reception – this band is empty here. Since I have modded my XDR-F1HD I can receive also everything above ~60 MHz during Sporadic-E propagations.
