If you'd said what started as WJBM-FM would one day be the home of the Mighty KMOX when it signed on, you would've been thought to have been crazy.
The fact that a class B signal was sitting up there in Jerseyville always seemed wild to me. But some research showed that WJBM actually got the allocation through an NPRM that it requested in 1966. It wasn't just sitting there in the table of allocations waiting to be used; someone actually did the analysis and figured it out.
By that time, "Doc" Ferdinand Gorecki and his wife Janet owned WJBM. They had gradually bought up other stockholders starting in 1963. The Goreckis ran a medical clinic in Jerseyville. I haven't found any indication of why they became interested in running a radio station as well. Then they added the FM facility, first at 15 kw in 1968, and then up to a full 50 kw in 1972. But both the stations and the clinic kept going until "Doc" died a couple of days after Christmas in 1978. Janet kept the stations until 1984. She sold them for $1 million, contingent upon FCC approval of a new transmitter site closer to St. Louis.
Before 1984, WJBM-FM mostly simulcasted WJBM(AM). I spent my high school years in St. Charles County, Missouri, where WJBM(AM) simply could not be heard but WJBM-FM was easily received. For much of my time in the area, the stations simulcasted from 6 am sign-on until 5 pm. THe format was typical small-town radio. One morning feature was bingo, sponsored by an IGA supermarket in Carrollton, Illinois. A small staff broadcast news and other announcements during the day. Music was filler, more or less either oldies or country. The FM was in mono.
At 5 pm, the AM signed off, the FM flipped to stereo, and a show featuring western swing and old-time country music aired. I don't remember the name of the show, nor the host's name, but he sounded as if he were 90 years old. I believe the program was brokered.
At 7 pm, there was "Ed and Alice's Old Rock and Roll Show". This was a brokered program, with quite a few ads from businesses, not just in nearby Alton, Illinois, but also in St. Louis County, especially North County, where WJBM-FM reception was more likely compared to other parts of the city and county. Of course, recpetion was just fine in St. Charles County, but there didn't seem to be that much of an advertising base there. I'll note that St. Charles had lost its daily newspaper in May 1978 and KIRL in St. Charles was beginning to struggle by that time as well.
At a time when oldies, when present, were a format mostly limited to AM radio, the WJBM-FM show was one of the few places it could be heard on FM. I recall the audio processing on the station: it had a "level devil" quality to it. It also sounded as if there was no noise gating. You could hear every breath an announcer took.
After Alton's WOKZ-FM sold to St. Louis' Laclede Radio (KATZ) at the end of 1978, becoming WZEN (now KATZ-FM) with only the daytimer WOKZ(AM) remaining as a station serving Alton, some local sports play-by-play that WOKZ-FM had carried was broadcast on WJBM-FM.
By 1984, my last year with any ties to St. Charles County, WJBM-FM had gone stereo full-time. "Ed and Alice's Old Rock and Roll Show" was still going. I have one recording of it; unfortunately, it was from a night when Ed and Alice (who were real people) were off and there was a substitute host instead. Monday nights by then were also given over to a show featuring contemporary Christian music, something that you also didn't hear much on the radio in 1984.
As indicated by the 1984 sale, the 104.1 frequency was an obvious St. Louis rimshot. The station's new site in Alton was farther south and closer to the St. Louis area. By 1985, it had become WKKX, a country station targeting St. Louis. I found a Post-Dispatch column by Eric Mink, published September 23 of that year, expressing some skepticism about the station's ability to survive in what had become a market with three country stations. But WKKX did survive.
In the 1990s, Zimmer Radio bought that station as well as 106.5, a full-market signal, once WGNU-FM, then WWWK, then KWK-FM, then WKBQ. Zimmer moved the WKKX country format onto 106.5, with WKBQ's CHR format moving to 104.1. While diminishing WKBQ's coverage in the St. Louis metro, reception of 104.1 in outstate Missouri was actually better. I could pick it up in Columbia about as well as most St. Louis FMs, but 106.5 always had to fight interference from a Kansas City-area station on the same frequency. The 104.1 frequency was a much clearer channel in east-central Missouri and even in Columbia.
Even with the move of 104.1 to an Alton site, I'm sure there was still spotty coverage in South County. KATZ-FM had the same problem with South County coverage. Ultimately, those stations' cities of license were changed to the North County suburbs of Hazelwood (what's now KMOX-FM) and Bridgeton (KATZ-FM), enabling the use of transmitter sites in St. Louis County itself.
Janet Gorecki passed away in 2012. Here's her obituary:
Janet Gorecki of Jerseyville Obituary | EdGlenToday.com - she remained active in business after selling the radio stations. Even though the radio stations weren't her main endeavor in life, I get the feeling that she was an astute operator.
While KMOX(AM) has a storied history of its own, KMOX-FM's history has its own interesting twists and turns, too.
