Harris Corporation recently completed the fourth in a series of DRM (Digital Radio Mondiale) digital radio demonstrations over the medium wave broadcast band for officials at Guang Dong Radio, Zhu Hai, China. Guang Dong Radio runs 80 radio stations, and serves more than 60 million listeners in southern China. An existing Harris DX 10 medium wave AM radio transmitter was converted to DRM for the nine-day digital broadcast demonstration at the Zhu Hai transmission site.
The tests demonstrate the cost effectiveness and ease of conversion to high-quality DRM performance for Harris DX(R) MW radio transmitters. According to Don Spragg, director of high-power radio and programmes for Harris Corporation’s Broadcast Communications Division, Harris’ DX series AM transmitters can be prepared for DRM transmission in an easy, one-hour upgrade session.
Harris has the largest installed base of DRM-ready, AM transmitters with more than 1,000 DX series, solid-state Medium Wave AM radio transmitters installed worldwide. DRM field-testing has been completed on DX transmitters from power levels of 10-kilowatts to 200-kilowatts.
Harris Corporation is a member of the AIB.
