history

Construction and commissioning

The Krvavec has been the location of a radio station since the early 1950s. After only a temporary solution was initially used, the first final transmission tower was built in 1957 and started operating as a television station on February 14, 1957.

Start of television broadcasts

Initially, the program of the Italian RAI was exclusively taken over , since there were no radio programs for Slovenia in the former Yugoslavia at that time . One year after commissioning, however, the company switched to the JRT program from Belgrade , which was produced for the whole of Yugoslavia and which was fed from the Sljeme station in Croatia using a radio link . Since May 24, 1965, a second program has also been broadcast from this station. In 1966 the first color broadcasts were started on a test basis and the signal in the RAI was temporarily taken over again until color broadcasts from Slovenia were also available from March 3, 1970. On May 5 In 1990, on the occasion of the Euro Vision Song Contest in Zagreb also stereo so.

The opening ceremony for the transmitter on Krvavec took place on November 12, 1960. At that time, the transmission power of the television program was 1 kilowatt , after only 250 watts were used when it was put into operation.

Start of radio broadcasts

Radio broadcasts on FM were first broadcast in 1961 by the Krvavec. Initially, only the second program was broadcast, until the first on November 28, 1966 and finally the third program on June 15, 1969. Stereo broadcasts were broadcast from March 4, 1967. At that time, the transmission power of the FM transmitter was 10 kilowatts.

Modernization in the 1980s

In the 1980s, extensive modernization of the transmitter system in Krvavec followed; not only the transmitter building was rebuilt from 1981 to 1985, but also the transmitter tower, which was completed at the end of 1988.

destruction

On July 2, 1991, the transmitter was badly damaged by Yugoslav fighter planes during the Slovenian War of Independence ; the resulting damage was estimated at half a million euros . A new transmission tower was built later; the old one had to be demolished due to severe damage.

today

Today the reinforced concrete tower on top of the transmitter building measures 100 meters. It supplies large parts of Slovenia with radio and television programs and can also be received in parts of the neighboring countries. Transmitters from Harris with an output power of 10 kilowatts are used for broadcasting on VHF.
