As far as I know, the only English-language ESPN affiliates in KC are WHB 810 and KCTE 1510/94.5. WHB doesn't air the daytime lineup for ESPN, and 1510 isn't on after dark. So, aside from weekends and some summer nights when KCTE can stay on until around 9:00 PM, the two don't simulcast. 94.5, of course, can stay on all night, but it essentially provides an FM companion for WHB after KCTE signs off.
There are other ESPN affiliates within WHB's daytime signal contour, but, like I said, WHB doesn't carry ESPN's daytime lineup. Plus, ESPN doesn't provide protection based on signal contours. WHB's nighttime signal doesn't do as well as it looks like it would on paper. In 1997, KCMO was on 810, and WHB was 710. Entercom, which had recently acquired KCMO (and its FM as well as KMBZ/KLTH) from Bonneville, approached Kanza about swapping signals because, despite 710 having a nighttime null that excludes Lawrence and cuts right through the present day Legends and The Woodlands and another one east of the tower site that cuts off some of the eastern exurbs, 810 had reception problems in the fast-growing Johnson County suburbs where 710 was stronger. 710's nighttime signal, while not nearly as good on paper, didn't get interference from the west while 810 could get stopped on by WBAP 820 and XEROK 800. I lived at 75th and Quivira at the time, and, while I never had problems getting KCMO/WHB 810, WBAP sounded more like a local after dark, and XEROK was quite strong, too. WHB found the deal enticing because it was running farm programming from KMZU and wanted to capitalize on 810's superior daytime signal. It didn't really care much that 810 had problems in Johnson County since it was trying to cover the vast rural area north and east of Kansas City. It was more worried about Johnson County, Missouri than Johnson County, Kansas!
To the best of my knowledge, though, there are no ESPN affiliates in the Kansas City area that are in areas where WHB's nighttime signal is weak. I believe Topeka has an ESPN affiliate, and I'm thinking there's one in Bethany along the Missouri/Iowa border, but, unless KSIS or KDRO in Sedalia has recently added ESPN programming, I don't think you'll find another one before Columbia heading east. St. Joseph had an ESPN affiliate in KESJ 1550, but it flipped to classic hits about six months ago.
