XEQC-AM was a radio station broadcasting on 1390 kHz in Puerto Peñasco, Sonora.
It was owned by Ángel Tanori Cruz and known as La Reyna del Mar.
XEQC received its concession on June 5, 1972, making it the first radio station in Puerto Peñasco.
The move never materialized, and the station ultimately ceased transmitting eight years later when the Federal Telecommunications Institute shut down 1390 AM as a pirate, imposing a fine on Tanori Cruz and seizing the station's equipment.
