When the FRC reallocated stations in 1927 and 1928, stations owned by educational and/or religious institutions tended to be at a disadvantage and were often forced to daytime status or to share time. WEW was then owned by St. Louis University, a Jesuit institution. It operated commercially but didn't have the political heft that stations such as KSD or KMOX possessed. (Even so, KSD was forced to share time with KFUO for 12 years, which resulted in a contentious relationship.) As for WEW's claim of being first west of the Mississippi, I would take that with giant grains of salt. When, in the 1990s, I was doing research into pioneering radio stations, I found that many such claims could not be definitely proved or disproved. Things were loose and easy in radio in the early 1920s; stations came and went without much documentation. The best source for tracking such things can be local newspapers but, even there, one must be cautious, because a lot of hype accompanied happenings in radio.
