A memorial from the Cold War
Orlunda longwave station. Or rather, Motala broadcast radio station
Motala broadcast radio station was the name of two radio stations that broadcast radio on the longwave band.
One is located inside Motala city and started to be built in 1926. The other is outside Vadstena city, in Orlunda and it is the one that is in focus this time for MSFS.
I have taken the liberty of placing a fictitious track in the area (ESVO). We must be able to land there ;)
In 1926, the Telegraph Board received a grant from the Riksdag to build a broadcast radio station.
This would be located in Central Sweden. They chose Motala because the city was "in the middle of Sweden" - the broadcasts from here would reach listeners in both Stockholm and Gothenburg.
The long-wave transmitter was of the Marconi brand. It was then Europe's strongest with a power of 30 kW. The broadcasts reached 20-30 miles from Motala.
But as early as 1934, the station was upgraded with a new 150 kw transmitter.
During the late 1930s, shortwave was also broadcast from Motala, with programs for Swedes abroad.
For this purpose, directional antennas were installed for North and South America.
During World War II, it was realized that the station could be a strategic target to attack.
Therefore, an underground transmitter bunker was built, which was equipped with a backup station.
In the mid-1960s, the operation was shut down and the Orlunda transmitter took over.
The longwave station in Orlunda was built in the late fifties and completed in 1961.
The idea of the Orlunda station was that it would withstand an atomic bomb war and be able to maintain transmissions that reached far into Europe.
The main building, which still stands today, is a massive bunker and is open to visitors on certain occasions.
It was a modern 2 × 300 kW station for parallel operation from the Compagnie Français Thomson-Houston (CFTH, today only Thomson).
The exhaust pipes were equipped with vapotron cooling, a CFTH specialty.
The antenna system was a unique ring antenna, developed by civil engineer Folke Strandén at Televerket, consisting of five 200 m high masts standing in a ring around a central mast of 250 m with a mutual distance of 630 m.
The project manager for the construction of the Orlunda station was Tore Myrén at Televerket's Radio Agency.
On July 12, 1970 at At 01:50 the center mast collapsed during a thunderstorm when lightning struck the mast and set fire to one of the oil-filled stay insulators whereupon one of the stay lines snapped.
The mast collapsed over the bunker. The bunker sustained minor damage due to its heavy construction.
The transmission frequency was generated by an extremely accurate generator, which allowed Orlunda to function as a normal frequency station for scientific purposes.
The range during the day was about half of Sweden, during the dark part of the day much greater, so that a large part of Europe was covered.
I can see no mast´s , is it depending on other downloads?
