6190 kHz 17 kilowatt DLF unit at Britz site was formerly erected by USIA branch "RIAS Berlin" radio station on 7 August 1951 - always on 6005 kHz in 49mb under "West-Berlin" in NASWA list counting. Meant for RIAS Berlin and VOA Washington program relays into East Germany (GDR - formerly Soviet Zone of Germany) and German nationals in Poland, Baltics, CSSR, Hungary and South Tyrol-Italy too. Location of former RIAS/VOA 6005 / now 6190 antenna visible next to small building at 52 26 50.57 N 13 25 49.93 E see green arrow at Protected and well-tended like a jewel when tender and loving care by Britz engineers long term. 73 wolfgang df5sx - - - See under "Kurzwellen-Faltdipol" 6190 kHz - Well, look here: The line "Kurzwellen-Faltdipol" shows the 6190 kHz facility. The shabby shack is the transmitter building, a provisional one from the earliest RIAS days. If I recall correct (it's 15 years since I was there) the vertically mounted fluorescent lamp behind one of the windows is in the very room of the shortwave transmitter. Otherwise there is only an ancient FM transmitter in this shack, if I recall correct. The other transmitters are in what the webpage calls "Hauptgebaeude". The antenna of the broken S4001 transmitter is the one labelled as "Kurzwellen-Antenne noerdl. des Hauptgebaeudes". I understand that each antenna is "hard-wired" to the related antenna, i.e. a swap is not possible. Originally cover has been provided by the complete 20 kW transmitter/antenna combination. When the separate 6190 kHz service started in 1999 the concept changed in as far as transmission breaks during maintenance or equipment failures are just accepted now. "Teil des demontierten Kreuzdipols" was a vertical incidence antenna with circular polarization for nighttime service on 990 kHz, now dismantled. At some point in the nineties further use of this antenna has been banned, because it produced too high fieldstrengths in the neighbourhood of the station. Since then mediumwave transmissions are limited to the two guyed masts, one of them carrying the 89.6 MHz antenna, too (the second RIAS FM frequency, 94.3 MHz, has meanwhile been moved to the TV tower). And a word about the transmitters: The remaining shortwave transmitter, the one in the shack, is rated at 20 kW and has been delivered by Telefunken in 1950, it is by far the oldest broadcasting transmitter in everyday use in Germany (and perhaps well beyond). The newer shortwave transmitter is or was an S4001, different from the file:///Z|/DOKUMENTATION-BULLETINS/WWDXD-BCDX/2010/BCDX976.TXT[11.06.2012 10:40:15]
ones used by Media Broadcast in as far as it got no SSB capability and has not been equipped for automated fast tuning. This transmitter suffered a failure of the transformer that produced the plate current in 2007, no such transformer was in the Juelich spare sparts stock due to the design variants (at least I understand this has indeed been checked) and a replacement would cost about 100,000 Euro, an amount nobody was willing to invest into the DX hobby (that's pretty much the reality now). The mediumwave equipment consisted 15 years ago of a 100 kW solid-state Nautel for 855 kHz, an S4003 (300 kW mediumwave version of the PANTEL series PDM transmitters, housings similar to the S4005 shortwave transmitter; this one was the first PANTEL ever delivered) for 990 kHz and an S4002 (PANTEL 100 kW mediumwave, looks like its shortwave brother S4001) as aux. Nowadays two Transradio TRAM transmitters are used as mains. And meanwhile word has it that in the last days there were some power supply problems with the 6190 kHz facility, but some necessary repairs have been done and now the old tranny should again happily churn away.

"The Longwave radio mast Hellissandur is a 412 metre high guyed radio mast for longwave transmissions at Gufuskalar in the vicinity of Hellissandur on the peninsula Snæfellsnes of Iceland. This mast, which is the tallest structure in Western Europe, is insulated against ground and guyed in 5 levels by steel ropes, which are subdivided by insulators. It was built in 1963 as replacement for a 190.5 metre (625ft) tall LORAN-C tower, which was built in 1959, for the North Atlantic LORAN-C chain (GRD 7970). After the LORAN-C scheme was shut down on December 31st, 1994 the longwave radio mast Hellissandur was converted to an aerial mast for a longwave broadcasting transmitter of the Broadcasting Service of Iceland, for a transmission frequency of 189 kHz and a power of 300 kilowatts."
