I have to agree with you on that, because WCCO on AM 830 (eight-three-o) and FM 102.9 could become a reality one of these days. As a matter of fact, if KMNB drops their country music format one of these days, then the WCCO-FM call letters would make its return to 102.9 for the first time since 1983, the year they changed 102.9 to adult contemporary WLTE.
I would like to also mention that radio stations have come and gone over the years. As a matter of fact, I remember a radio station out of Texas, KOGT, and it was based in Orange, Texas. In fact, I got an opportunity to listen to the station via their livestream during their final days on the air as well as the last few minutes of the station on the evening of December 31st, 2021. The reason they signed off the air was in part due to changing media. However, as I am replying to this post, I went to http://www.kogt.com and their website is still active even after the station signed off the air back on New Year's Eve 2021 as they update the latest news each day. So, when they sign the station back on the air will be interesting to watch, but I'm not for sure if it will ever sign back on since they have been off the air for almost a year.
Getting back to WCCO, I will restate that WCCO on AM 830 and FM 102.9 could become a reality, and would give WCCO a clear FM signal.
