This is possible thanks to the new transmitter on the Etzel, which in future will also cover the Linthgebiet, Obersee and Ausserschwyz regions on the 88.4 frequency. The new transmitter on the Etzel replaces the previous Feusisberg site, from which Radio Zürisee broadcast for the communities around Obersee and in the Linth region on 91.9 MHz.
 

In mid-December, Radio Zürisee switched on its future most important transmitter on the Üetliberg. Thanks to this transmitter, reception in the city of Zurich, its agglomeration and the district of Dietikon will be optimized, according to a statement from Radio Zürisee. With the commissioning of three further transmitters, Radio Zürisee can now be received without gaps in the districts of Affoltern, Bülach, Dielsdorf and Andelfingen. The radio station has already been heard in Winterthur and the surrounding area for several weeks. Radio Zürisee thus increases its listener potential to 1.5 million.
Tunnel coverage is also being expanded. At the end of January 2010, the very busy Gubrist Tunnel on Zurich's North Ring will be connected.

New transmitters on the Zürichberg and Albis ensure better reception in the city of Zurich, while two more on the Bachtel and Feusisberg provide better coverage of the Zurich agglomeration. In addition, the needs of commuters are also increasingly being met, as Radio Zürisee can now be received without gaps in the Milchbuck and Schöneich tunnels. Thanks to a new transmitter network structure, the previous frequencies can be switched off. The expanded broadcasting area will also be taken into account in journalistic terms, with plans to expand regional reporting.
