The first transmitter was built in 1927 and started operation in September 1928 with the transmission from a fair in Ljubljana, and later a solemn broadcast of Franc Finžgar talking about Slovene language and Oton Župančič reading verses from his poem Duma.
A t-antenna with 5 wires, it was hung on two 120-metre tall steel framework masts, which were insulated against the ground.
It was destroyed by German airplanes on 11 April 1941, during the invasion of Yugoslavia in World War II.
In the course of the roll-out of the Geneva wave plan the transmitter got the licence to work with an output power of 600 kilowatts and the facility was renovated in the second half of the 1970s; not only were new transmitters installed, but the old radio mast was replaced by a 161-metre high guyed mast of steel tube, which is insulated against the ground.
On 2 July 1991, during the Ten Day War, the station was attacked by two Yugoslav Mig-21 airplanes, and the 600-kilowatt transmitter was heavily damaged.
