This transmitters used a self-radiating 51 m mast as antenna.
Since 1998 the main transmitter for 783 kHz, which three years later
became the only one at all, is a Thomson M2W that sits in the original
FM/VHF transmitter building. See at bottom of
... which indeed provides about the best possible views, the sight is
basically just that of some metal plates, with the air vents being the
only clear indication that this *is* the transmitter. A new antenna has
been provided with the M2W, very similar to the now removed ones of the
old transmitters:
These antennas are an East German staple, but I never saw them on photos
of transmitter sites abroad, with the only exception being the Koepenickbuilt
Pleven in Bulgaria. Any comments on this aspect?
Besides this the M2W can also use the above mentioned 51 m mast at reduced
power of 20 kW, which is what this standard design permits. This happens
not too seldom, just every time work on the main antenna takes place.
Perhaps you remember that Mitteldeutscher Rundfunk decided in 1995 to use
783 instead of 531 kHz from Wiederau. 531 was a very good daytime
frequency, one would have guessed rather 300 than 100 kW for it. 783 is
noticeably poorer, and at night things become really bad. Perhaps you
remember my reports about a 1 kHz het, which turned out to originate from
Syria. Just 90 km away from a 100 kW station! Of course the DCC system
does not help by making such interferences more prominent, lacking the
full carrier in pauses, but still quite some people think that MDR should
better have ridden out the Beromuenster co-channel situation, since now
this problem would have been evaporated.
For FM/TV see
At top the current FM transmitters in the former UHF building, below the
test cards the TV transmitters that have now all been removed.
In the pre-1990 era most FM/TV equipment originated from Funkwerk
Koepenick, plus some own construction, plus some added Zarat (Poland)
equipment. Feeds came in via microwave (in place for TV anyway), also for
the MW/SW transmissions, with cable connections being only a back-up.

SWR-cont.ra hat den Mittelwellensender Ulm (Jungingen) von 711 nach 1413
kHz verlegt. Die alte Frequenz wurde am 8. Maerz 2010 abeschaltet, die
neue am 10. Maerz 2010, 09.30 Uhr, in Betrieb genommen. Zugleich wurde die
Sendeleistung auf 1 kW reduziert. Die SWR-Mitteilung verspricht den Ulmern
"einen deutlich besseren Empfang", doch die Frage ist nun, wie sich die
neue Ulmer Frequenz 1413 kHz neben den starken Signalen der
