Broadcasting on 93.3 FM, XHQQ is owned by Grupo Radio Centro, and is promoted as "Banda 93.3".
XHQQ began life as XEH-FM, authorized for the even-decimal FM frequency of 93.2 MHz on a concession awarded on December 21, 1963.
[2] At the time, Mexico had authorized about 20 FMs on even-decimal frequencies, primarily as studio-transmitter links, though a special few were authorized as main stations; XEWV-FM 89.6 Mexicali, XEH-FM 93.2, and XHM-FM 88.8 Mexico City were among this group.
XEH changed calls to XHQQ in the late 1960s, and it remained the last even-frequency FM standing as of 1970.
[3] In the early 1970s, XHQQ came in line with most other radio stations in the Americas by moving to an odd-decimal frequency, in this case 93.3.
