Dear Farmer
I once asked a list of Swiss radio stations here together. It has this case even two German channels, but which are receivable in Switzerland. These are Radio Regenbogen and SWR. 3
The list includes the following channels:
SRF 1
SRF 2
SRF 3
SRF 4 News
SRF virus
SRF Musigwälle
Radio Argovia (Kt. Aargau)
Radio 32 (Kt. Solothurn to Bern)
Radio 24 (Kt. Zurich)
Radio Top (Eastern Switzerland, Thurgau to St.Gallen)
Radio Basilisk (Basel)
Radio Zürisee (city of Zurich until Except Switzerland)
Radio Sunshine (Central Switzerland, train, Schwyz and Lucerne)
Radio 105 (Anywhere in Switzerland, but especially in the city)
Radio Regenbogen (Baden-Württemberg, North Switzerland)
SWR 3 (Baden-Württemberg, Bavaria, North Switzerland)
Couleur 3 (French, French-speaking Switzerland to Geneva)
I wish you with the transmitters have fun, and may they beautify the fieldwork something.
It greets you, your Amunrah.
