XHEMU-FM
XHEMU-FM and XELRDA-AM are La Rancherita del Aire, two radio stations serving Piedras Negras, Coahuila. They broadcast on 103.7 FM (HD Radio) and 580 AM, with the ranchera music format. The stations are owned by Claudio Mario Bres Medina (La Rancherita del Aire, S.A. de C.V.).
History notes: The station began as XEMU-AM 580, with the original concession dated March 10, 1937, awarded to Alfonso Bres Burckhardt. After his death, ownership passed to the current owner. It moved to FM in 2011, and its transmitter site was updated in 2015. In the 2017 IFT-4 auction, La Rancherita del Aire bought back the 580 AM frequency, which now uses the callsign XELRDA-AM.
Technical details: XHEMU-FM runs at 5 kW (HD Radio) and XELRDA-AM at 3 kW. XHEMU-FM was authorized on July 17, 2024 to broadcast three additional subchannels.
