Sorry, I wasn't clear. I meant it's pretty much impossible for all the TV providers to sync up with the radio broadcast. There are way too many things going on in the background for every provider to be synced perfectly. The solution you mentioned does work well if you have the patience to get it synced.Actually, it's very possible with today's technology.
All you need is a radio (or connected device) or radio app, if using a phone or similar, that will let you pause the radio feed so the TV can catch up.
