The year 1983 in radio involved some significant events.
January 3 – Following its sale to Sconnix Broadcasting, WLLR of East Moline, Illinois debuts at 101.3 FM and moves its studios to Davenport, Iowa. The station carries over a country format, which had been used by its previous owner under the previous call letters WZZC, which had been in place since 1978. The station continues its steady climb in the Quad-Cities Arbitron ratings and eventually becomes the market's top-rated station.
August 2 – WHTZ (Z100) in New York City debuts, soon becoming one of the most influential CHR stations in the US. Z100 has competition in the format from 95.5 WPLJ, which flipped from album-oriented rock to CHR on June 30 of that year, but it is Z100 which gains the lion's share of the attention by literally going from "worst to first" in the ratings.
March 16 – Arthur Godfrey, 79, 27-year host of Arthur Godfrey Time on CBS, as well as host of Arthur Godfrey's Talent Scouts (on radio from 1946–1956; on TV from 1948–1958); one of history's most influential broadcast personalities.
August 4 - Yuri Levitan, 68, Soviet Russian radio announcer.
