U.S./Mexican border - Jun 19, 2008 - In May 2008, Mexico's Federal Telecommunications Commission (Cofetel) authorized radio stations with about 200 miles of the U.S. border to transmit HD Radio signals.

XEEZ 970 Radio Palacios is broadcasting an AM HD Radio signal from the U.S./Mexico border town of Caborca, Sonora, using a Broadcast Electronics transmission system. XEEZ adapted its BE AM 6A solid-state transmitter for linear transmission and added a BE ASI 10 exciter to generate the HD Radio signal. XEEZ ordered the exciter and the transmitter through BE representative Distribuidora E Importadora de Radiofusion, S.A. (DIRSA).

XHTY in Tijuana has installed a Nautel V10 HD Radio transmitter. The station is operated by Uniradio. The company now operates 12 stations. Five of them serve the San Diego-Tijuana region and seven serve the Mexican state of Sonora.
