radiotutkan

Radiotutkan refers to a Swedish radio transmitter that operated from 1937 to 2000. The name is derived from the Swedish language, with "tutka" being an obsolete word for "receiver" or "listener". The radio transmitter was used for domestic broadcasts, transmitting programs from the Swedish Broadcasting Corporation to thegeneral public.

The Radiotutkan transmitter was a short-wave radio station, operating on frequencies between 14 and 21 MHz. It was primarily used for broadcasting radio programs from the Swedish Radio Domestic Service to listeners in Sweden during the winter months when atmospheric conditions often disrupted the coverage of medium-wave radio signals. The transmitter was located at the RCCV broadcasting center in Saltsjöbaden, a suburb of Stockholm.

In the 1930s and 1940s, Radiotutkan played an important role in radio broadcasting in Sweden, increasing the country's radio outreach to listeners in the colder, darker months. It remained operational until the end of the 20th century, when it ceased operations due to advancements in medium-wave and long-wave radio broadcasting technology, which made Radiotutkan's services redundant. Today, Radiotutkan is remembered as an important chapter in the development of radio broadcasting in Sweden.
