Most radio call signs are arbitrary letters assigned by a regulator. XHRJ-FM's are not. The station's identifier is a small tribute to the man who put it on the air in the first place, decades before it became Toluca's outlet for Grupo ACIR's romantic music format.
A Call Sign Built From a Founder's Initials
XHRJ-FM received its broadcast concession on August 15, 1980, under owner Javier Ramírez González, and the call letters RJ are a reversal of his own initials, according to the station's Wikipedia entry. It is a small detail, but it ties the station's identity directly to the person who launched it, a naming convention that has outlasted his ownership by more than four decades.
A Quick Handoff to Toluca's Broadcasting Family
Ramírez González held the station for barely a year before selling it in 1981 to Corporación Radiofónica de Toluca, the company that would eventually become part of Grupo ACIR, per the same Wikipedia record. That early sale set the station on the path toward the network it belongs to today, trading a single owner's name for one of Mexico's largest romantic-format radio chains.
Mexico's Leading Romantic Radio Chain
Grupo ACIR itself traces back to June 8, 1963, when Francisco Ibarra bought station XEDQ-AM in San Andrés Tuxtla, Veracruz, beginning a career that started at age 17 as an accountant at Radio Mil, according to El Financiero's profile of Ibarra. The Amor format he built the network around now runs across 19 Mexican cities as the country's leading chain of romantic music stations, built specifically around what the network describes as themes of love, friendship, family and health.
An Hour Built Entirely Around One Singer
The Amor network's programming includes "La Hora de Luis Miguel," an hour dedicated exclusively to the singer's catalog that first launched in 2002 at the height of his chart presence, was quietly shelved during a period when he stepped back from new releases and touring, and returned to the schedule after the success of his biographical series revived interest in his music, according to El Universal. The show now runs daily from 7 to 8pm, drawing on songs the biopic reintroduced to a new audience.
One Frequency, One Long Romantic Format
XHRJ-FM has changed hands and identities since 1980, but the through-line from Javier Ramírez's original station to today's AMOR 92.5 is a straight one, a Toluca frequency that settled into Grupo ACIR's romantic format and has stayed there ever since. The call sign is the only piece of that original 1980 station still broadcasting on the dial.
