The Sistema Quintanarroense de Comunicación Social (SQCS, English: Quintana Roo Social Communication System) is the state broadcaster of the Mexican state of Quintana Roo, founded on January 30, 1985. It operates several television and radio stations in the state. The SQCS entered radio with a three-station AM network, with transmitters at Chetumal, Cancún and Felipe Carrillo Puerto broadcasting on 860 kHz. The first of the three to come to air was XECTL-AM "Radio Chetumal", still in operation, which signed on May 4, 1985. XECCN-AM 860 in Cancún, known as Radio Caribe, took to the air on June 24 that year, and the radio service extended to Felipe Carrillo Puerto with Radio Chan Santa Cruz XECPR-AM the next year. The SQCS later added a fourth AM station when it built Radio Riviera XERRIV-AM 1180 in Playa del Carmen. XECCN and XERRIV no longer operate. More information...
