International electronics and systems group Thales has announced that a new
world record has been reached in Macedonia for Digital AM Broadcasting. PE
Makedonska Radiodifuzija (MRD), the national public broadcaster, in
collaboration with Thales and Deutsche Welle (DW), succeeded in transmitting
720 kW mean power in Digital Radio Mondiale (DRM) mode from the mediumwave
station Ovce Pole, the highest DRM power ever broadcast by a single
transmitter, reaching exceptional coverage and quality of reception.

Transmissions were done on 810 kHz with the Thales' S7HP 1200 kW solid-state
mediumwave analogue transmitter, in operation at Ovce Pole since its
inauguration in June 2002. For the tests, Thales provided front-end
equipment from its Skywave 2000 DRM Digital Product Line.

The necessary measurements of the signal quality and coverage area were
performed by DW using their measurement van and various fixed control and
measurement centers in Europe. Measurements were carried out twice a day: 3
hours during day time -groundwave propagation- and 3 hours during night
time - skywave propagation- while transmitting the program of Macedonian
Radio. The DW measurement van confirmed a coverage area during daylight of
up to 300 km, whereas by night the DW centers recorded reception over larger
areas of Western Europe. The audio quality was excellent and disturbance
free.
