Gonna chime in on the out-of-sync thing. Here in the office, I stream WRTI on the computer, despite the wretched sound, as the radio is not reliable. I am 15' underground and dead-center in a city-block large hospital complex.. But those few times I can get WRTI on FM, the stream is about 1/2 second behind the OTA signal. So something causing cross-talk, or something going out-of-sync and affecting OTA signal makes perfect sense.
