I listen to WBBM 780 am every morning on my way to work, I heard their broadcast cut out to the typical EBS annoying tone, they made no mention of a test comming up, the broadcast just stopped. My stomach sank a bit as it didnt feel right I could hear talking and a bit of what i guess you could describes a a digital tone, I couldnt get my radio up loud enough to make out any of what was being said, and wrote it off as the studio folk still talking not knowing the EBS had been activated. Then it cut back in with another am station I told a coworker about it he said that was weird. Later In the aftrnoon WBBM had a 15 sec report about how FEMA caused it, no one knows why or how but investigators are looking into it.
Does anyone know if this was across am and fm?
