XEQ-AM

XEQ-AM (940 kHz) is a commercial AM radio station in Mexico City.¹ The concession is held by Cadena Radiodifusora Mexicana, S.A. de C.V.¹ and is operated by Radiópolis.²³ It airs a Spanish-language adult hits radio format known as "La Q 940."

XEQ is a Class A, clear-channel station, powered at 30,000 watts. The other Class A station on 940 AM is in Montreal, far enough away that XEQ does not need to use a directional antenna to avoid interference. XEQ's transmitter is at Los Reyes Acaquilpan, on Boulevard Generalísimo Morelos, east of Mexico City.⁶

XEQ began operations in 1938. It was owned by Emilio Azcárraga Vidaurreta doing business as Radio Panamericana, S.A., and was a network affiliate of CBS Radio as part of the "Chain of the Americas."⁷ It was Azcárraga's second station after XEW-AM. By the 1960s, XEQ was operating with 150,000 watts during the day and 50,000 at night. In the 1970s, it switched to 100,000 watts day and night.⁸ It later reduced its power to 50,000 watts.

The XEQ call sign later appeared on other stations: XEQ-FM was licensed in the 1950s, and the original XEQ-TV, broadcasting to Puebla, signed on in 1952 to relay XEW-TV. (In 1985, a call sign swap led to a different XEQ-TV in Mexico City.)

In 2014 and 2015, XEQ was approved to lower its power from 50,000 to 30,000 watts.

Until 2019, the station was known as Ke Buena but carried a tropical version of the format, instead of the typical grupera version. On October 31, 2019, this ended and XEQ-AM began simulcasting XEQ-FM. On August 18, 2023, the simulcast ended and XEQ-AM was relaunched as "La Q" with a Spanish-language adult hits format, mostly consisting of tropical, regional Mexican, grupera and romantic music from the 1970s to the 2000s.
