Europe’s Most Powerful MW Station Updated with Nautel

Nautel’s largest transmitter, a 2 Megawatt NX2000 Medium Wave system, has been fully commissioned and is now on the air at Antenna Hungaria’s transmission facility near Solt, Hungary. The project involved large infrastructure changes at the site as well as installation of the new transmitter.

“The NX2000 system incorporates five Nautel NX400 transmitters along with a large, versatile combiner,” said Wendell Lonergan, Nautel Head of Broadcast Sales. “Our new NXC2000 combiner can be reconfigured if one or more transmitters is shut down, which ensures that maximum power is delivered to the antenna in all cases.” Nautel worked closely with Porion Digital KFT on the installation, which included building renovations and air handling modifications as well as interfacing the NX2000 to Antenna Hungaria’s existing 11kV voltage supply. The solid state Nautel system replaces an aging custom-built tube transmitter that had been in operation for 40 years.

Antenna Hungaria is wholly owned by the government of Hungary and provides broadcast, telecommunication and multimedia services throughout the country. Their Solt operation is the most powerful medium wave radio transmitter in Europe and one of the most powerful transmitters in the world. Its signal on 540 kHz can be heard all over Europe as well as in parts of Africa, Russia and Asia.

The new NX2000 system brings high efficiency – 90 percent – and significant power savings to an operation that had been running at around 60 percent efficiency with its older equipment. Nautel’s high power NX transmitters, in addition to their high efficiency and outstanding reliability, offer a compact footprint for significant space savings. Individual transmitters are available in 100, 200, 300 or 400kW designs, along with lower power units ranging down to 3kW. As with all modern Nautel transmitters, control and monitoring are accomplished via Nautel’s award winning Advanced User Interface (AUI).

“Nautel has been entrusted with some of the world’s largest Radio broadcasting projects in the past few years,” said Kevin Rodgers, Nautel President and CEO. “This 2 Megawatt transmitter, along with the world’s largest DRM deployment in India and other opportunities around the globe, have strengthened our abilities to provide world–class transmission solutions as well as the best customer service in the industry. We are honoured to have been chosen for these important projects.”
