I live in a big city in the west of my country. We have 5 + 1 state stations, 1 federal station, 1 by the British military, 1 from the university (students studying journalism), and 1 private station. If you're in the west of my town, you also get the private station from the neighbouring city.

Every household has to pay a radio & TV tax for the state stations. (Some states like NRW, Bremen and Hessen have their own broadcasting corporation, others share one. Like for example the federal states of Hamburg, Schleswig-Holstein, Niedersachsen and Mecklenbeck-Vorpommern share the Norddeutscher Rundfunk, North German Radio (and TV)).

FM is called "ultrashortwave" (UKW) here has a range of about how far you can see. So people living in the country may get a lot less stations than I do. I live in a metropole region where the emission wattage for the stations is limited in order not to interfere with the stations of neighbouring cities. It's still pretty good, but I noticed that I get no reception at all when I'm directly under the tower.
