Per German RadioEins.de Website:
On February 20, 2015 begann a Oromo Community in Minneapolis (USA) to produce a weekly radio program and broadcast it to Ethiopia. It runs each Friday from 19.30 bis 20.00 clock CET on 15165 kHz.
At least in the main, is this program dedicated to the Islamic religion. This corresponds to its presentation as a Radio Risala, in original spelling in Oromo, as Raadiyoo Risaalaa.The understanding of "Risala" in Islam is a mediator between God and Man.
On the Internet and by phone are these productions already spread for some time. When the first broadcasts on shortwave started, it seemed to be the show #184. As the announcement on Facebook shows,the transmission time and the exact frequency are apparently not even clear to the organizer.
The broadcasting on shortwave was arranged by the one-man company "Broadcast Belgium". Their usual partner, and in this case also Raadiyoo Risaalaa, are restricted to range of possible transmitter sites, such as shortwave facilities in France, Bulgaria and Pridnestrovie.
Further background can be found on the Facebook profile, and the incomplete website risalainternational.org but without knowledge of the language Oromo no further details are recognizable. A Eye catcher on Facebook is an entry in English from January 14th, that encourages to boycott Google because of the Youtube Video "The Innocent Prophet", which contains the exclamation "USA is losing."
The name "Radio Risala" had appeared in shortwave broadcasting in 1994 for a short time. But then via the transmitter Bolshakovo in the Kaliningrad region.The broadcasts back then are likely unrelated to the current activities. They are also not to be confused with an homonymous FM station in Mogadishu.
I am sorry for the rough translation using Google translate but I modify the article as good as possible to make somewhat sense.
