[3] The stations each carried a J for Jalisco in their calls and one initial of then-governor Silvano Barba González's last name.
Reports, though, often mangled XEJG's calls as XEJC because Barba González grew to be unpopular when his term concluded in 1943.
In 1999, XEJLV-AM 1080, a daytime-only station in Puerto Vallarta, was permitted, extending the reach of the AM service.
The result was that XEJB-AM became XEPBGJ-AM and its Puerto Vallarta relay became XEPBPV-AM, following a templated callsign pattern used since 2016 for some new radio stations.
[4] The station never returned to air because the tower necessary for its operation exceeded height limits for obstructions near the Puerto Vallarta airport, and the concession was surrendered on April 25, 2022.
