A hint at what radio used to be:
You’d think an original three-letter call from the 1920s would be worth preserving, but apparently not: starting in 1984, KWK went through a dizzying variety of call letters, ending in 2015 as KXFN. Before it was KWK, it was KFVE, and over the years they moved from 1280 to 1350 to 1380. For a while, there was also an FM, at 106.5. This made for some interesting situations:
Since the AM and FM stations were licensed in different cities, KWK was only allowed to simulcast on both frequencies for a portion of the day. John Hutchinson remembered “when the AM and FM broadcasts were split, the FM jock would play the playlist from the top of the page down and the AM jock would play tunes from the bottom of the page up. When the time came to simulcast we would pick a tune over the intercom and try to begin the tunes at the same time so that we could flip the ‘simulcast’ switch and purportedly no one would detect the merge. Of course this did not always happen smoothly … causing much hilarity amongst the air staff.”
The station has been silent since last December. The Mutual Broadcasting System was killed by Westwood One in 1999; the “Muny,” still in Forest Park, continues.
