I don’t have a recording, so I can’t prove it, but yesterday during the Rush Limbaugh show on San Francisco 610 am KSFO, around the last hour I heard the start of an EBS.
The show was transitioning to commercial and overlaid with the audio, I heard the squeek/squak of the computer modem tones used on the audio equipment at the start of the EBS.
It never made it to the single tone of BEEEEEE, but just switched the screeching back to the commercial.
Probably a fluke, but when I heard it I got so excited fir a split second.
Probably just a test we do get those you know.
Yes. Typically start of month
