The development of broadcasting technology made Mount Krim of increasing interest due to its dominant location. In 1971, the Slovenian broadcaster RTV started building a transmitter on the mountain in order to provide television coverage to an area that could not be reached by the transmitters at Mount Krvavec and Ljubljana Castle. The Yugoslav military also took an interest in the location and started building its own facilities at the same time as RTV. The summit of Mount Krim was then closed to hikers and other members of the public, who could go no higher than Mount Krimšček (941 m), also known as Little Mount Krim (). While it was used by the military, the mountain was an important radio point for the army, serving as a radio and radio-relay point that covered most of Slovenia and also maintained contact with similar points throughout Slovenia and the rest of Yugoslavia. The exterior of the military structure indicates that it was similar to that found at Guslica on Mount Risnjak. In 1991, during Slovenia's Ten-Day War of independence, Slovenian Territorial Defense units sought to force the staff at the facility to surrender, but without success. The structure continued to be used by the Yugoslav military until October 1991, when the Yugoslav People's Army withdrew from Slovenia. After 1991 the summit was again accessible to the public and the military structure is more or less abandoned. Next to it there is a small mountain lodge, which is visited by thousands of hikers every year.
