Sorry if the title is confusing. My local FM sports station plays a program every Sunday morning at 6 am. I’m up at that time and it’s one of the only FM stations that I can pick up on the radio next to my nightstand.

It sounds interesting but it’s unlistenable: it’s like one audio file is being played on top of the other half a second apart. Ads too. It’s only on the FM side: steaming online does not have this problem.

When the program concludes, everything goes back to normal. It infuriates me. I’ve messaged the station on Facebook three weeks in a row politely pointing this out. I can see the message read, but no change is made.

What is happening on a technical level, so I can point that out when I message them again?
