So do they just own the Nauen site then act as a broker for airtime on other stations for what they don't have the capacity for?
Yes, or if another site would be better to reach a atrget area.
And one more question, what exactly is Shortwaveservice? The way I understand is they have their own 1 kilowatt site at Kall, but on their website it sounds like they also transmit programming from Nauen, Moosbrunn, and I believe one other side,
Shortwaveservice:
* operates low power transmitters in Kall on 3985 / 6005 / 6085 / 7310 kHz
* brokering airtime mostly via own transmitters, Bulgaria and some CIS sites
* producing a monthly media magazine in German language broadcasted via Nauen, own transmitters and sometimes also via other sites
