Three-Letter Roll Call

Thomas H. White -- January 1, 2014

In-depth review of the broadcasting stations on the AM (mediumwave) band, which have been assigned three-letter callsigns.
Sections

Background

This is a comprehensive roll call of the three-letter calls used on the standard AM band in the United States, up to January 1, 2014. The main list reviews three-letter calls assigned to standard AM broadcast stations. This list is the result of an exhaustive review of official government records. Ideally, it includes every three-letter call ever assigned to a standard station on the AM band. Government and temporary stations, for which there is less complete information, are reviewed separately.

In many cases these three-letter calls had previously been assigned to ship or non-broadcast land stations. Also, many were later assigned to related FM and TV stations. However, these lists only review stations in the AM band.

Standard AM Stations (by call)

The main list contains 250 entries, which comprise 242 distinct stations, because in eight cases--KGC/KNX, KZC/KOG, KZN/KSL, WBL/WWJ, WCM/KUT, WCX/WJR, WEB/WIL, and WGL/WOV--a single station accounts for two different calls. There are only 231 different calls, because in 15 cases--KGO, KOA, KSL, KZC, WBL, WDZ, WGH, WGM, WIL, WJZ, WMC, WMH, WNJ, WOK, and WPG--the same call was used at different times by two different broadcast stations, while KGB and WGL have each been used by three different stations.

Each entry in the main list begins with the three-letter call, the studio location at the time of the call assignment, and the date of the first assignment of the three-letter call. In most cases the entry reflects the licencing of a new station. However: The Status column lists the eventual outcome of the three-letter assignment. In cases where the three-letter call is no longer used the ending date is listed, followed by an equal sign and information on what occurred: either the station was deleted, or a new call was assigned. In the 56 cases where an AM station still holds the original three-letter call, the call is repeated along with the current frequency. Additional information includes current call, frequency and location for stations which have changed from the original information.

In some cases there have been breaks in usage and other aberrations, which are noted in the gap between "1st Assign" and "Status".

Chronological List of Significant Actions

The following is a chronological list of all significant three-letter callsign actions taken from May 1921 through January 1, 2014, for every three-letter call used by standard stations on the AM broadcast band. "Significant changes" are defined as: newly licenced stations, stations transferred to the broadcast service from a previous classification while keeping their old three-letter call, call letter changes affecting a three-letter call, call transfers from one station to another, community-of-licence changes from one state to another, station consolidations, and permanent station deletions.

Changes deemed "not significant" enough to be included in the list were: community-of-licence changes within the same state, transmitter location changes, station deletions which were immediately followed by a relicencing of the station under the same call, and any changes before or after the station used a three-letter call. Three columns with "running totals" are included in the list. "Total on AM" is the number of three-letter calls on the AM band after the action took place. [NOTE: Since the chronological list omits cases where stations were deleted and then shortly thereafter relicenced, in some cases in the early twenties this total includes one or more stations awaiting relicencing.]

Starting with 8/5/1957, "Not on AM" reports the number of "independent" three-letter calls, i.e. held only by an FM or TV station after being given up by the original AM station, while "All Bands" is the total number of unique three-letter calls in use on AM, FM and TV, i.e. "Total on AM" plus "Not on AM".

                                                                   Total
                                                                   on AM
                                                                   =====
