Here in Springfield, IL, usually a country duel between WCRC Effingham, IL and KWWR (the legendary "Country 96") Mexico, MO.
In addition, KWWR and their 100,000 watts was quite a regular catch in my family's area during my pre-teen/teen years in the late '80s/early '90s (especially during 1990-91, which IIRC seemed to have plenty of DX/tropo) about 30 miles northwest of Peoria, IL (and also about 125 miles as the crow files southwest of Chicago). Even after WGLO Pekin/Peoria bumped up from 95.3 to 95.5 in spring 1989 (with their current 7 kw/620 ft.).
In fact, also around this time (1990-ish) KWWR went a little over the edge IMO about their coverage area in their station IDs--I vividly recall hearing one where they boasted about serving parts of Missouri, Iowa and Illinois (although realistically at that time I would say they reliably reached at best a Burlington, IA-Macomb, IL-Jacksonville, IL-St. Louis arc on a regular basis during the day, then the rest was tropo and/or night). In addition, KWWR frequently (and may still do) referred to "Mexico-Columbia-Quincy" (and occasionally Jefferson City) in their legal ID--and for a time around '90 again even said "ALL OF THE MIDWEST"

after "Quincy." (when in reality it was a little closer to "all of the Midwest except about 75 miles either side of Effingham, IL").
Was KWWR "Country 96" a frequent visitor to other parts of the Midwest on 95.7 particularly during 1990-91 (e.g. could there have been reception reports for KWWR even in the Chicago area in spite of 95.5 there).
