It went live on 15 December 1930 with a transmitting power of 60 kilowatts, using a vertical cage antenna, which was hung with a rope spun between two 102 metres (335ft) tall free-standing wood towers 200 metres (660ft) apart. In 1935, the transmitting power was increased to 100 kilowatts and the vertical cage aerial was replaced by a dipole with top capacity and coil, which was carried by a 115 metres (377ft) high free-standing wood tower. In 1940, this was replaced with a 151 metres (495ft) high guyed mast of square cross section lattice steel, which was insulated against ground. In addition, a triangle plane antenna and a 50 metres (160ft) high guyed mast (also insulated against ground) were installed.
On 31 January 1945, the facility was largely destroyed by the withdrawing Wehrmacht armed forces. After World War II a transmitter was operated on the site by the Soviet Foreign Service. From the mid 1950s until the mid 1990s a local program was broadcast there with low power. A shortwave facility for cross-border skywave jamming beamed towards the Soviet Union, Czechoslovakia and Bulgaria has existed in Lidzbark Warmiński. The jamming facility was shut off for good in late 1988.
The present-day Broadcast Transmitting Site (Polish: Radiofoniczny Ośrodek Nadawczy, RON) at Lidzbark Warmiński which has a 83 metres (272ft) tall antenna is today used for broadcasting of Radio Maryja on 106,2MHz with 10kW ERP and the TV programme TVP 1 on 527,25MHz with 200kW ERP.
