In southward, westward and northward direction, the repeater covers about 80 km, until into Belgium and the Netherlands. However, stations from the vicinity can dominant be heard. In eastward direction, the coverage bounds to 10-20 km, because Düsseldorf is located to the eastern border of the lower Rhine lowlands.

Listen in
The transmission of the repeater can be heared via the Internet. *
Real time status: It was not possible to determine whether the repeater is active just now.
In addition to the high frequency transmission the output of repeater will be transmitted over the internet. The real time live recording is provided on different audio formats. Used are the speec codec Speex (0-16 kBit/s), the universal codec Vorbis (8-16 kBit/s) and alternatively the music codec MP3 (24 kBit/s). For playing back a streaming-capable audio programm such as VLC media player, foobar2000, MPlayer or xine is needed. Compared to the high frequency transmission the playback can be heard 8 to 20 seconds delayed, depending on the codec.
If currently nothing can be heard, this could be due to there is no communication via the repeater at the moment.
* The possibility to listen in is currently a test phase.
