The Harris Corporation has announced that Brazil’s Rádio Globo has ordered two high power AM transmitters for sites in Rio de Janeiro (1220 kHz) and São Paulo (1100 kHz), which will also be equipped with exciters for HD Radio™ broadcasting. Rubens Campos, General Director of Sistema Globo de Rádio says that “Going digital, especially on the AM band, is the only way that radio can grow its audience.”
Rádio Globo currently has a 3DX™-50 transmitter at the Belo Horizonte site (1150 kHz) broadcasting analogue and HD Radio signals since September 2005. Now, Rádio Globo Rio and Rádio Globo São Paulo will install 3DX™D-200 transmitters. Radio CBN Rio (860 kHz) will also install a 3DX™D-100 transmitter, while Radio CBN São Paulo (780 kHz) will add a 3DX™-50 to its family of transmitters. Redundant exciters and power supplies will be integrated, ensuring that each station will remain on the air at all times. Rádio Globo has also purchased three HT35CD FM transmitters for stations in São Paulo and Rio de Janeiro, three BMXdigital on-air consoles and one additional 3DX-50 high-power AM transmitter, originally installed at Radio Tiradentes in Belo Horizonte.
