Krim transmitting site is built on the Krim mountain south of Ljubljana. The need for transmitting site at Krim emerged in early 1970s because there were some gaps in the radio and television coverage areas of the Krvavec transmitting site. Preparation works for the Krim site started In 1971.
After it was build the first broadcast from this site was Slovenian public television channel TV Ljubljana 1 (now TV Slovenija 1). Soon after in the year 1973 another transmitter (more precisely transposer) started broadcasting Croatian public television channel TV Zagreb 1. Microwave links with other transmitter sites were also installed.
In 1979 the second Slovenian public TV channel TV Ljubljana 2 started broadcasting. In 1982 FM radio transmitters for the public radio stations Radio Slovenija 2 and Radio Slovenija 3 were transferred from Ljubljana castle site to the Krim site. In 1996 also the public radio station Radio Slovenija 1 started broadcasting from this site. There are also commercial radio stations broadcasting from Krim: Radio Aktual and Radio Ekspres, 3 commercial TV channels: Kanal A, POP TV and TV3 and 1 DVB-T multiplex.
