New England Radio Station Call Letters: What do they stand for?
From the beginning days of Radio, the Federal Radio Commission (later the Federal Communications Commission) assigned all letters to various stations, in alphabetical order.  That is, KAA to KZZZ and WAA to WZZZ.  However, owners of stations could request call letters based on any number of criteria.  For example, WHB in Kansas City stood for "World's Heart Beat."  St. Petersburg, Florida's WFLA stood for the then-abbreviation for the state of Florida, Fla (WFLA was originally licensed to Boca Raton, Florida, until that station went dark).  Call letters have been used to identify the initials of station owners, locales they served, slogans, and more.

New England Radio stations had, and many still retain, call letters based on the above.  Our visitors have collaborated on the following list, based on AM stations' original call letters.  If you can add to this list or correct it, please let me know. Some stations on this list have either changed call letters or gone off the air entirely.  The main purpose of this list is to show the meanings of the call letters; not reflect current station history.  I am interested only in New England stations dating from before or just after 1960 when radio was king!

* = No original meaning, calls were sequentially allocated by the government.

The following from a former WJAR employee who was kind enough to make the correction: The story as related in The Outlet Story by Samuel Chipman Smart:

"An old-time rumor had it that WJAR's initials came from James A. Reilly. This, of course, is absolutely false. Reilly was not employed by WJAR until 1924, two years after the station began broadcasting. Actually, WJAR's call letters were assigned by the Boston office of the Department of Commerce. As Ray Blanchard remembers it, he and two Department of Commerce inspectors ... went to Boston to apply for call letters in August 1922 and came back with the letters WJAR. Blanchard recalled, 'We didn't like the damn call letters, but we were stuck with them.' "
