I did check Doc and according to the American Federal Communications Commission: "Since the early days of wireless telegraphy, starting with marine use, radio stations have had their own identification.

Under international agreement, since 1927 the alphabet has been divided among nations for basic call sign use.

The United States, for example, is assigned three letters--N,K, and W-- to serve as initial call letters for the exclusive use of its radio stations. It also shares the initial letter A with some other countries. The letter A is assigned to the Army and Air Force; N to the Navy and Coast Guard, and K and W to domestic stations, both government and non-government."

We learn something every day, lol.

I get my music from country gospel all over the world but it's nice to hear your input:)
