22 Nov New DRM on shortwave transmissions from Germany
“funklust”, campus broadcaster at Friedrich-Alexander-Universität Erlangen-Nürnberg, stands out as one of the radio stations with the most diverse transmission paths in the world. Recently, the station has revamped one of its digital broadcast paths: funklust in Digital Radio Mondiale (DRM) on shortwave is now broadcast using a new, modern transmitter.
In the summer of 2003, funklust (known as “bit eXpress” back then) was broadcast digitally for the first time on shortwave (SW) using a Telefunken transmitter. Transmission via DRM on FM radio later followed in 2013, with funklust becoming one of the first DRM radio programs in the world to be broadcast on FM. The entire broadcasting apparatus for DRM on shortwave has now been modernized and funklust has been broadcasting with brand new equipment since October 2021. A Fraunhofer ContentServer R7 is used to broadcast the program, allowing audio content and attractive data services, such as Journaline, TextMessage+ (TM+), and even Emergency Warning Functionality (EWF), to be put on air with ease. The funklust transmitter requires an average transmission power of 250 W and operates at the transmission frequency 15.785 MHz. Reception reports received so far confirm that the program can be received not only in Germany but also in Russia, the US, Norway, Finland and New Zealand.
Until recently, a dedicated radio device was required to receive DRM transmissions. Starwaves, a developer of DRM receiver solutions, worked closely with Fraunhofer IIS to develop an Android app, which can be used for DRM reception on mobile devices. The Starwaves radio app is available in the Amazon App store and the Google Play Store and provides Android cellphones and tablets with entertainment, text information and emergency warnings via DRM digital radio — without the need to enter into a contract, independent of the user’s mobile network and based on innovative Fraunhofer technology.
