It's a pretty simple set up for NBC Radio News and iHeart's 24/7 News.
If you are an NBC affiliate, your newscast starts with the NBC sounder and I assume a voice saying "NBC Radio News." Then we hear the anchor give his/her name and starts the lead story.
If you are a 24/7 affiliate, this is a white label service. Nobody ever says "24/7" or "iHeart." The newscast simply begins with anchor saying his/her own name and starting the lead story.
It’s NBC News Radio. Other than that everything else is spot on.
