I hope they get it fixed. But I might have been a little too strong with "useless". It was still nice to be able to turn it on after a big play to get the radio guys take.
I'm guessing that whomever is in charge of actually turning it on before the games is doing something wrong, because I've definitely heard it both live and delayed at different times. If you turn it on before the game begins, you can hear whatever goes over the stadium PA, such as the music played during BP. So it seems like someone is manually switching it over to Charlie & Dave, and maybe they're piping in the wrong feed on occasion.
By the way, you can listen in on a regular radio if you have one that will pick up 68.5 MHz. There are some cheap ones available on Amazon.
