It was broadcast by the transmitter "Sender Bisamberg", on the frequency 1476 on medium wave, hence the name of the station.

In 1933, a transmitter with a 100 kW performance was put in operation and was blown up in 1945, at the end of the Second World War by SS troops.

From May 3, 1999, the radio was very engaged with Nachbar in Not, a charity project for the Balkan area.

After the re-commissioning of the 600 kW transmitter, it was possible to send information to the conflict areas in Yugoslavia, which were affected by the war.

The program was broadcast on medium wave, on 1476 kHz.
