Hörby station
The Hörby transmitter has existed since 1937. Initially, it was broadcast from there on medium wave 1,178 kHz. It was Sweden's only commercial radio station that also broadcast on shortwave frequencies. The shortwave was mainly used for broadcasting the international program of Sveriges Radio to inform Swedes abroad. Since 1959, programs for VHF and television broadcasting have also been broadcast.
history
Choice of location
The Hörby location was chosen for the medium and short wave transmitters so that they were as far away as possible from the annoying northern lights and as close as possible to the continent.
Medium wave
The first Hörby transmitter was a small 10 kW transmitter in Karlsfalts, a few kilometers from today's premises. It had been in operation since 1928 until 1937 the premises in Östra Sallerup, about 8 km south of Hörby, were completed with a new 100 kW medium wave transmitter from Telefunken. A guyed 130 m high steel lattice mast served as the antenna at the new location. The transmitter had to stay in operation until 1947 because it was difficult to get new tubes and other spare parts during the war. A new 100 kW transmitter could only be ordered and installed from Standard Electric & Cables Ltd in Great Britain after the war. This transmitter had to be kept in operation with considerable effort in its last years, until finally in 1985 the medium wave transmitter Sölvesborg could be put into operation on 1,179 kHz with 600 kW. The transmitter in Hörby was scrapped immediately after the shutdown. The transmitter mast was blown up and scrapped in the spring of 1985. The old transmitter from 1937, which was kept as a reserve until then, can now be seen in the Königs Wusterhausen transmitter museum .
Shortwave
Since July 1, 1938, there have been regular test broadcasts on Wednesday and Saturday evenings. The broadcasts in German over shortwave (6,065 kHz, 49 m) did not officially begin until May 8, 1952, when they were also broadcast by the longwave transmitter Motala . In the late 1960s, two new shortwave transmitters were ordered from Thomson , which were installed in the early 1970s. They replaced the two Marconi transmitters from the late 1940s, which were already slightly used when they were bought. The efficiency of the old transmitters was only about 50%. After 20 years of operation they were taken out of service because the high-voltage oil capacitors contained polychlorinated biphenyls . Officially they were scrapped, but were actually used as replacement transmitters, one in the shortwave station of the Norwegian state broadcaster NRK in Fredrikstad and the other in Gambia. In 1992 three more efficient shortwave transmitters ( PDM- modulated) with 500 kW from the manufacturer Thales Swiss were installed. They could be used for frequencies between 5,800 and 21,600 kHz.
Antennas
The antenna park consisted of nine curtain antennas in the directions 70, 150, 190, 250 and 290 degrees and two logarithmic-periodic antennas that could be rotated between 0 and 360 degrees. One was located next to the southern curtain antenna G1 on a 60 m high half-timbered mast, which however fell over in 1999 during a winter storm. This antenna was not rebuilt. The station was manned during office hours and was remotely controlled the rest of the time. The medium wave transmitter in Sölvesborg was also remotely controlled from Hörby. All shortwave broadcasts from Sweden ended on October 31, 2010. At the beginning of April 2011, the antenna park was completely demolished as it was considered hopeless to find a new tenant who could replace Radio Sweden. The shortwave transmitters were bought by Radio Nederland Wereldomroep , RNW, and installed in the spring of 2011 for a new life for 5 to 6 years at the RNW transmitter site in Madagascar.
Todays use
Various VHF and TV radio programs are now broadcast from the Hörby station. As early as 1959, a 323 m high guyed steel truss mast was erected as an antenna carrier for this purpose. When it was inaugurated on October 1, 1959, the mast was one of the tallest structures in Europe. In addition to various directional radio antennas, it mainly carries the antennas for VHF and television broadcasting. The VHF broadcasts can be received in neighboring Denmark as well as partially in Germany, namely on the island of Rügen and in the northern rest of Mecklenburg-Western Pomerania.

Mux 1-5 send in DVB-T and Mux 6 + 7 send in DVB-T2.
Mux 7 transmits in the VHF range because there are no more UHF channels available at the Hörby location.
