Due to a typographical error, some later sources incorrectly list the station's first airdate as "May 24, 1921", which is actually exactly three years before the actual date of the station's initial test transmission as reported by Stanley Krohn.[2] This incorrect year appears in the May 1962 issue of Broadcasting magazine ("Radio stations 40 or more years old in 1962" ("WING Dayton, Ohio" entry), Broadcasting, May 14, 1962, page 132.) However, on May 2, 1929, reflecting its actual establishment in 1924, it was reported that the station, now WSMK, was in the process of celebrating its fifth anniversary.[3] The 1962 Broadcasting magazine entry also makes an erroneous reference to the supposed initial use of the call letters "WXAX", which was not actually assigned to any stations at this time.
