BANDA 93.3 (Monterrey)

Banda 93.3 (XHQQ-FM) broadcasts on 93.3 FM from Monterrey, Nuevo León, and is owned by Grupo Radio Centro.

The station began as XEH-FM, with a concession awarded on December 21, 1963, to broadcast on the even-decimal frequency of 93.2 MHz. At the time, Mexico had authorized about 20 even-decimal FMs, mostly as studio-transmitter links, and only a special few, including XEH-FM, were authorized as main stations. In the late 1960s it changed calls to XHQQ, and by 1970 it was the last even-frequency FM still standing. In the early 1970s it moved to 93.3, coming in line with most other radio stations in the Americas.

It later came under Grupo Radio México, whose largest station cluster is in Monterrey. In 2015, ownership was transferred to Grupo Radio Centro as GRC absorbed the concessionaires of 30 GRM stations; the two companies share family ownership. In October 2015, Emisoras Incorporadas de Monterrey, S.A. de C.V. was replaced by Radio Emisora XHSP-FM as the concessionaire as part of a restructuring of several GRM stations.
