According to Taehyun Kim, a professor of journalism at Cal State Northridge, at times the station acted as a literal walkie talkie. "People would call to make sure their store is OK. Since there was no way to get there because of a curfew," Kim told LAist. "So someone would call to ask about a place. And, if someone nearby listens to the radio program, they would call to tell you 'No, Johnny's swap meet has basically burned down completely to the ground, sorry.' And the [original] caller would say 'Oh my god, I don't know what to do tomorrow.'" Kim says this back-and-forth was also used to mobilize emergency efforts. "A caller would say, 'Here's a shoe store burning down at such and such. Let's go help put out the fire. We need volunteers.'"
