Radio Station
In the United States, the first letter generally is K for stations west of the Mississippi River and W for those east of the Mississippi; all new call signs have been 4-character for some decades, though there are historical 3-character calls still in use, such as WSB Atlanta, WBZ Boston, and KOA Denver. There are a number of exceptions to the east/west rule, such as KDKA in Pittsburgh and WFAA in Dallas-Fort Worth, but these are historical artifacts from a rule change in the 1930s, and most of the exceptions are located in the states immediately to either side of the river. The westernmost station in the continental United States beginning with W is WOAI in San Antonio. WVUV-LP in Pago Pago, American Samoa, is the westernmost station with a W call sign. KYW in Philadelphia is the easternmost station with a K call sign.
Canada uses CF-CK, CY-CZ, VA-VG, VO (Newfoundland), VX-VY, and XJ-XO.
