The Swiss Broadcasting Corporation used shortwave outlets to re-broadcast its domestic services. Below are three QSL cards from the Swiss PTT Enterprise for reception reports of the domestic services.
Swiss Radio International (SRI) was a fixture on the shortwave bands in its heyday. Who can forget their music box interval signal when they signed on? SRI was founded in 1935 and left shortwave in 2004. The Swiss international broadcast service continues on the internet using the moniker of SwissInfo.
Below is gallery of QSL cards collected from them over the years, including one from SwissInfo in 2003 (very bottom one in the gallery here). Beginning in the 1980’s they transmitted from various relay stations throughout the world in addition to their Switzerland sites.
