I managed to hit the wrong tab and signed myself off from RD last night, taking my post with it. I'm going to say KKCW Beaverton OR on 103.3 during some tropospheric ducting events.
As another idea, what would be the closest you could get to one of the non-directional 50kW Class A Clear stations around sunrise/sunset, and have it completely covered (uncopyable and un-DX-able) by a co-channel station on day facilities? (Also midwinter midday skip counts, too.) Only include stations licensed within the USA - no Canadians, Cubans, Mexicans, etc. Bonus points if you're close enough to the Class A for it to trip the seek on an average radio at midday in summer, better yet if most female friends (great-grandmas to wives to great-granddaughters, cousins, aunts, nieces, etc) consider it to be perfectly listenable. (I'm referring to midday summer reception of the Class A.)In such a case, what might be the location, the offending Class D (or Class B) station, and the affected Class A?

New one: 94.9 MHz in Muskegon, MI
Probably a mess between W235BN/Grand Rapids, MI, WMMQ/Lansing, MI, WKZC/Scottville, MI, WSJM/Benton Harbor, MI. Also WOLX/Barabo, WI would be common. You'd need a good directional antenna to separate them but you'd still have W235BN and WMMQ in pretty much the same bearing from Muskegon.
I was driving through the Muskegon area on Friday and I was getting mostly WMMQ, with an occasional WOLX. I was getting W235BN around Nunica. WMMQ was still dominant on 94.9 as far north as Rothbury. WKZC is one of the worst underperformers I can think of on FM. For 17kW from between Ludington and Manistee, you'd think they would make it to Muskegon. And I haven't seen an STA for low power operations.
If the Quad Cities wasn't on the air, I have no idea. I'm not aware of other past or present *8"s out that way.
Maybe WISH, Indianapolis?
And a different twist to this thread, while testing your knowledge of early TV history and allocations. And from the "which signal was most likely, if any" department:
TV Channel 8 about 2 miles northwest of the small town of Brimfield, IL (between Peoria and Galesburg) any time from the period August 1955-July 1963.
All of this during the fight over the original channel 8 allocation for Peoria--which was later moved to Moline, IL (when the FCC decided to make Peoria an all-UHF market other than for the Quad Cities and Champaign V's making reception appearances in the immediate Peoria area) and signed on as WQAD Aug. 1, 1963.
On Google Maps, the pinpointed mark is roughly the area of my hypothetical question of what might have appeared on Channel 8 there from Aug. 1955-July 1963.

MAYBE then-KRNT from Des Moines or WKBT from LaCrosse, WI might have been able to ride in from time to time when atmospheric conditions were favorable. Both were using tall towers in the years immediately leading up to 1963. I snagged WKBT once about ten miles from my current location before WQAD come into existence. Captain Kangaroo, Mister Greenjeans, Bunny Rabbit, and Grandfather Clock were all there.

Possibly, or WOOD-TV from Grand Rapids
Here's another "what might have been more likely to have been received in where in what year" TV question:
Channel 2 in 1956 at a farmhouse near Route 66 about 15 miles south of downtown Springfield, IL
During another Illinois FCC VHF/UHF deintermixture crisis: the move of the Channel 2 allocation out of Springfield, IL and to St. Louis (where it became KTVI). Plus being able to shoehorn another channel 2 for Terre Haute (becoming WTWO in 1965). The same FCC decision which moved Channel 8 from Peoria to Moline also claimed the Channel 2 allocation for Springfield.
My initial guess might have been WBBM, but I'm wondering if southwest of Springfield WMT Cedar Rapids, IA or even KFEQ (now KQTV) St. Joseph might have been more frequent than WBBM down here. And of course all the tropo. Other thoughts and guesses?
WLW-D was on a short tower back then due to being co-owned with WLW-T in Cincinnati (I only use the hyphen because they did). Might not have been capable of making the trip.
I will try to answer my own question, based on my experience (albeit growing up in the 80s/90s), since I grew up near that general area and experienced my own fair share of exciting DX and tropo moments on my own bedroom TV growing up (13-inch 1989 model RCA with the rabbit ears/bowtie that came with the TV in my bedroom, then "power" antennas later. Plus the family TV).
[. . . ]
If I was to guess what was most common to appear on 8 near Brimfield, IL on 750-foot farmland around 1956 with a good TV and good antenna tower with rotor on channel 8, but had to choose one channel--my first guess, based on my DX/tropo experience, would be KRNT. Plus if similar conditions existed after Aug. 1, 1963 after WQAD signed off for the night or was off the air temporarily due to technical problems.
New one:
103.5 MHz in Ontario, Ohio (about halfway between Cleveland and Columbus)
