BE Provides Transmitter for First Mexican Public AM HD Radio Demo

June 1, 2007

Morelia, Mexico - May 26, 2007 - One hundred and seventy station owners and engineers attended the first public demonstration of AM HD Radio broadcasts in Mexico on May 26. XEXL AM 690 in Patzcuaro, Michoacan, broadcast AM HD Radio live through a BE AM 2.5E transmitter as part of the demonstration, which was held in conjunction with the 71st convention of the Camara Nacional de la Industria de Radio y Television (CIRT) in nearby Morelia. Broadcasters gathered at the station's studios to listen to XEXL programming off-air on a variety of HD Radio receivers.

The AM demonstration comes just weeks after Mexico officials approved HD Radio for the country's AM and FM stations located within 200 miles of the U.S./Mexico border. For the demonstration, Felipe Padilla, BE's field engineer in Mexico, adapted XEXL's four-year-old BE AM 2.5E transmitter with the addition of a BE ASI 10 HD Radio signal generator and retuned the stations folded unipole antenna. An Orban 9500 audio processor was also on loan for the demonstration.

XEXL 690 is operating HD Radio under experimental authority from Cofetel, Mexico's broadcast regulatory agency, with authorization to transmit in HD Radio indefinitely for observation and measurement purposes. AM HD Radio is of particular interest to broadcasters here, as two-thirds of the radio stations in Mexico are broadcasting on the AM band.
