Trivia: What does the W at the start of a radio station’s call sign indicate?
East of the Mississippi
West of the Mississippi
A rock station
A military station
Correct Answer: East of the Mississippi
So why is this answer correct? : Most radio stations in the U.S. have a call sign that starts with either K or W. These acronyms date back to 1912 when an international conference agreed that certain letters should be assigned to different countries for radio and TV signal identification. The letters assigned to the United States were W, K, N, and A. N and A are used to identify military stations. Meanwhile, radio and TV stations east of the Mississippi were assigned W, and those west of the Mississippi were assigned K.
