TASHKENT - UZBEKISTAN
NEW 100KW SHORT WAVE TRANSMITTER
100 KW TASHKENT UZBEKISTAN
 Thomson delivered one 100kW
Shortwave transmitter to
Tashkent, Uzbekistan, in
December 2011
 Tashkent is located at the famous
Silk Road that was the most
important trading route from
China to the Mediterranean Sea
 The radio station was established in the late 1950. The ten 100kW transmitters
manufactured in the former DDR and installed in 1957/1958 are still “On Air”,
confirming the myth that the soviet design will last for centuries
 The radio station is mainly acting as a relay, servicing Asian countries like Nepal,
India or Iran
 The new transmitter will offer the customer a wide range of new opportunities of
modern transmission aspects, as outstanding AM and DRM qualities, easy and
straight forward operation with the ECOS control system and energy savings due
to high efficient transmitter technology
