I listen to a lot of radio and I rarely hear a legal ID. It's such a minor obligation, but nobody does it anymore. But Really Mr. radioman, "what a legal ID? " I'll use WTOS as the example.
There are only four ways that station can give a legal ID!
1. "WTOS, Skowhegan." That's the calls followed immediately by the city of license.
2. "WTOS, 105.1 on your dial, Skowhegan." That's the frequency or channel said between the calls and the city of license.
3. "WTOS, owned by Clear Channel Communications, Skowhegan." That's calls, owner and city of license.
4. "WTOS, owned by Clear Channel Communications, 105.1 on your dial Skowhegan" That's the ownership and the frequency are inserted between the calls and the city of license.
Despite the very narrow set of correct possibilities, Stations everywhere do it differently. KABL once got into trouble for ringing a rather loud cable-car bell so no one could hear the word "Oakland" in their legal ID. At WFLA in Tampa runs a legit ID in a jingle every hour on the hour. In Providence Rhode Island, WHJJ-AM, used ot have a similar jingle for their legal ID then they tradded it out for an all-girl chorus singing the call letters followed by a low male voice dropping the city of license almost inaudibly
