Resumen:
The London-based Czechoslovak exile government’s radio broadcast was during the Second World War a very important source of information about the real situation in the Protectorate of Bohemia and Moravia. Concerning it to be a part of the resistance, the Protectorate government banned listening to foreign radio stations and clearly claimed that those who would listen to foreign radio stations would be sentenced to jail or to death.
