What about KVYB Santa Barbara, CA, near / south of Bakersfield?
Somebody mentioned it before, but I wanted to note 92.3 - WXLK Roanoke (Va.) vs. WKRR Asheboro (N.C.) - again b/c it's a slugfest between two monsters There is a long stretch south of Martinsville where these two mix it up.
Both are ostensibly directional, but a look at Radio-Locator shows that neither has an exceptionally profound null toward the other. WKRR delivers 100KW ERP from 1289ft HAAT at 1995 ft elevation (big stick) and WXLK responds from 95.8 miles to the north with 93KW ERP at 2051 ft HAAT at 3976ft elevation (Poor Mountain). The other big FM's on Poor Mountain are non-directional 89.1 WVTF, 94,9 WSLC and 99.1 WSLQ. WSLQ has the most power, but runs into WZFX (itself 100KW) from near Fayettervile in this region, leaving WSLC to make the deepest reach in NC. It's quite listenable BEYOND WKRR's stick on US 220 into Asheboro, and along sections of I85 between Durham and Petersburg last time I ran that way.

93.5 WZCR (Hudson) and 93.7 WYAI (Scotia) tend to battle it out around Troy and Albany, but it seems like WZCR is usually stronger even that far north.
WCQL (Glens Falls) and WBEC (Pittsfield) are both on 95.9 and interfere with each other in southern Rensselaer County as well, with it changing almost every hundred feet or so.
But perhaps the worst in the Albany area is the fact that 98.3 WTRY (Schenectady) is close to both WCTW 98.5 (Catskill) and WCKM 98.5 (Lake George) and it's a real pain to get WTRY in either direction
Aside from that, that's all I can really think of

I only focussed on the commercial band, which I listen to the most. Anything in bold are local to me. For overall co-channel interference, 99.9 is the worst for my area, and even more so in the summer, with both WCPQ & WHFB having 50kw signals.

The biggest one around here is an adjacent channel situation, actually:
92.3 WKRK Cleveland Heights (CBS alt-rocker "Radio 92.3")
92.5 WDJQ Canton (locally-owned top 40 "Q92")
Both class Bs, they fight it out in nearby Akron, and there are many parts of Akron that can get both on radios with decent separation. But many radios hash them up, with the fringe of each signal interfering with the other depending on what part of town you're in.
West of Akron, adjacent channel stations fight it out:
100.1 WNIR Kent (locally-owned and programmed talk "The Talk of Akron")
100.1 WSWR Shelby (Clear Channel classic hits "My 100.1 and 98.3" in the Mansfield/Ashland market)
Since Kent is east of Akron, many areas an Akron station would presumably serve get WNIR with a small side sniping dish of WSWR. This happens especially around Medina.
Our worst co-channel radio situation is actually over on the AM dial, where:
1520 WJMP Kent (locally-owned syndicated talker, co-owned with WNIR)
1520 WINW Canton (locally-owned gospel)
...are just 20 miles and change apart. The co-channel situation is so bad, it basically kills any attempt by WJMP to serve nearby Akron. The station sounds bad in a large chunk of Summit County, and is unlistenable downtown Akron and south...

The one and only Scott Fybush says WJMP and WINW are 22 miles apart.

In SD Co the main issue is adjacent channel separation with the LA stations, but there are a few co-channel conflicts depending on what part of the county you are in.
96.1 KRQB (San Jacinto)/KSIQ(Back when the COL was in Brawley mainly)
99.9 KTXD (Santa B)/KOLA (San Berdoo)
103.3 KVYB (Santa B)/KTMQ (Temecula)
96.1 KRQB (San Jacinto)/KSIQ(Back when the COL was in Brawley mainly)
99.9 KTXD (Santa B)/KOLA (San Berdoo)
103.3 KVYB (Santa B)/KTMQ (Temecula)
99.9
KOLA/San Bernardino
KTYD/Santa Barbara
come together for an absolute mess at the ends of their respective coverage areas

Oh, WUPE/North Adams and WDST/Woodstock are both on 100.1... surprised I didn't remember that last timedanikayser84 said:93.5 WZCR (Hudson) and 93.7 WYAI (Scotia) tend to battle it out around Troy and Albany, but it seems like WZCR is usually stronger even that far north.

Aside from that, that's all I can really think of
Also, WZMR/104.9 has so many adjacent channels in each direction... WSPK to the south, WAMQ to the east, WVTL's translator to the northwest and a bible-thumper translator (not sure of the calls) on 104.9 in Glens Falls.
Heading north, WQBK/103.9 gets blocked by another of Chartock's stations, WANC/Ticonderoga (ex-WXTY) too, around Glens Falls and Warrensburg...
Just saw my message here again, and WDJQ/92.5 is actually licensed to the Canton suburb of Alliance.

WDJQ 92.5, there's a monster signal there. I used to get them crystal clear in Washington, PA
In my area it would by WSOL 101.5 (Soul 101.5/ Jacksonville) interferring with WPOI 101.5 (1015 The Point/ Tampa) Hit a bump in the road or make a turn and I can hear WSOL.
Another one will be WXCV (Citrus 95.3/ Homosassa) interferring with WPYO (Power 95.3/ Orlando). Drive out in the eastern side of the County and you can hear both stations at once. Or even worse going east on Highway 44 out to Wildwood and I-75. Cox Radio did directionalize the transmitter of WPYO to a easterly direction. (Manily to prevent this from happening.) However it still gets really bad in certain areas covered by both channels concurrentely.
WXCV in its bumpers claim to serve Eastern Citrus Counties as well as Northern Sumter County. However the signal is so noisy and garbagey in those areas its almost false advertising.

The worst case of this I can remember is while driving between Charlotte, NC and Columbia, SC and trying to listen to 104.7 fm. WNOK from Columbia starts interfering with the 104.7 in Charlotte starting around Rock Hill, SC and its nothing but the two stations flip flopping and fluttering for a good 30 or 35 miles from there south. This was back in 2003.
The worst case that I remember involved two full-power stations here in Texas on 95.5; in fact, it might have been one of the worst in the entire country and it lasted a long time. For instance, twenty years ago KNFO Waco operated with 100,000 watts from an antenna 1100 feet up, while down Interstate 35 in Austin KKMJ ran 100,000 watts at 1000 feet. Originally the stations should have been located 180 miles apart under FCC rules at the time, but the actual distance between them was just 74 miles.
The grand-fathered short spacing was corrected in the late 1990's when the Waco station (now known as KBGO) changed to 95.7 and downgraded to a Class C2. The operating parameters of both stations changed somewhat since then but KBGO currently runs 24,000 watts at 505 feet. KKMJ, which remained on 95.5, currently has a substantially lower ERP at 49,000 watts and their antenna height is just over 1300 feet.

Houston has notorious issues with two rimshots, KFNC 97.5 and KHJK 103.7. Both stations serve the greater Houston market, but are located some 60 miles east of downtown, and are regularly affected by KFTX 97.5 and KOUL 103.7 from the Corpus Christi area. KFNC also has issues from KWTX-FM 97.5 Waco.
When tropo conditions are really bad, KKWR 93.7 can be overtaken by KLBJ-FM Austin on the NW side of the metro.

Aside from the rare skip situations, the only problem I have here involves 92.7, where a C3 licensed to Belle Plaine south of Wichita (tower north of Wellington) messes up at C2 out of Minneapolis, KS (tower midway between there and Salina). Believe it or not, it's usually the C3 that overpowers the closer C2. (I'm at about 1500' AMSL, the elevation drops over 200' by the time you get to Wichita.)
Around Middletown Ohio the WBZI translator in Xenia messes with WMOJ on 100.3, and there are 2 short spaced 99.5s

WINC and WCNR
I live in the rule area of Hanover county north of richmond virgina. A company known as Summit Media has recently launched two new LPFM signals to rebroadcast digitcal only stations that they have on their main signals side channels on 1037 HD 2 and HD 3 feeds W223AZ-FM 92.5 MHz which completely displaces WINC WicFM on 92.5 MHz out of Winchester Virginia. Their signal was always strong for over 14 years before this new translator signed on the air and W291CL-FM 106.1 MHz which blockes reception to WCNR 106.1 The Corner form Charlettsville Virginia. Their signal gets overtaken offen not far south from Charlettsvile. I have made contact with both station owners about this as well as for WINC fm as well. Their signl was the strongest of the two and now being completely displaced.
