A 600 kW DRM enabled MW transmitter was installed on 15th March 2010 at Al-Arish, Qatar by the state broadcasting company. The overall project included the installation of two TRAM 300 AM transmitters, one Paralleling Unit (PU), two digital DRM Exciter DMOD2, and an antenna for medium wave frequency 675 kHz. Antenna design & construction was by Thomson Broadcast & Multimedia GmbH & was commissioned from Schifferstadt. New antenna design was developed in collaboration between Thomson & Transradio that meets the requirements for the future signal encoding.
The result is a transmitter with an impressive signal quality. Despite the relatively low frequency DRM mask a reserve of 6.17 dB in the real antenna is achieved. In addition, logs the efficiency measurement spot with values up to 88.6%, the continuous development and improvement of the TRAM-channel series of TRANS RADIO. The transmissions will begin in the next few days. With this transmitter, an older station near the Qatari capital of Doha will be replaced.
