What's in a name? Especially if that 'name' is just some seemingly random letters? The L.A. Times has done a pretty extensive article on radio station call letters and how they came to be. Not surprisingly, most of the stations described are in Los Angeles, but it also deals with other areas of the U.S., along with how one section came to use "W" in the east and "K" in the west. 

And there's a fun section of call signs that meant nothing but owners made up what they stood for. 

It's not local, but I found it a really interesting read on a subject most news outlets never touch. 

Where did L.A. radio and TV station call letters come from? And why do they all start with K?
