➦In 1922..WNAX 570 AM in Yankton, South Dakota, signed-on. The station is now owned by Saga Communications and airs News/Talk.
WNAX broadcasts at 5,000 watts around the clock from a tower in eastern Yankton. Due to its location near the bottom of the AM dial, transmitter power, and South Dakota's flat land (with near-perfect ground conductivity) the station's 5,000-watt signal provides at least secondary coverage during the day to most of the eastern half of South Dakota, much of western Iowa, and most of the densely populated portion of Nebraska.
WNAX was first licensed on November 7, 1922, to the Dakota Radio Apparatus company, and is the oldest surviving radio station in the state of South Dakota. The call-letters came from a sequentially assigned list, and WNAX was the last station in the state to receive a callsign starting with a W instead of K (other than sister station WNAX-FM), as additional stations in the state were established after the January 1923 shift that moved the K/W call letter boundary from the western border of South Dakota to the Mississippi River.

➦In 1940..WBZ-FM Boston first signed-on-air.
The first WBZ-FM had its origins in a construction permit held by Westinghouse Electric & Manufacturing Company to operate at 42.6 MHz; this facility signed on as W1XK from the Hull transmitter site of sister station WBZ-AM . Westinghouse soon sought a commercial FM license, and on February 19, 1941 was granted a construction permit for W67B on 46.7. W1XK left the air for good on December 28, 1941, and W67B signed on March 29, 1942. The call letters became WBZ-FM on November 2, 1943. Initially, W67B/WBZ-FM was largely separately-programmed, though in later years it became a simulcast of its AM sister station.
