Most European countries have this setup of "sub bands" for national FM networks, so they can generally be found within a range - BBC Radio 2's "88-91 FM" for instance. The Netherlands rearranged their FM spectrum in the 2000s to put network transmitters close to one another, previously it was a bit more chaotic.The usual Denver, CO - “Front Range Country” K276FK, fed by KQKS-HD2.
Right now in Leiden, South Holland, Netherlands - Two adjacent channels, both for national network Radio 10: 103.0 Hilversum and 103.2 Rotterdam. The Rotterdam signal is stronger here. In the crowded west of the country, it’s pretty common for the national networks to have stations that are in the same vicinity within a narrow range of frequencies, usually 200-600 kHz. Boosters would have been an ideal solution but they’re not used here.

Where national networks have grown through the acquisition of local stations, they are scattered up and down the band, like with the Heart or Greatest Hits Radio networks in the UK, or most of the French networks, but generally public broadcasters have little "slots" within the FM band.
In the Manchester area, UK - 103.1 is splatter from the local 103.0 transmitter of a fairly quotidian CHR network called Hits Radio, better remembered as local "Key 103".
The 103.1 tower for WHUZ, later WOWO-FM was on U.S. 24 not far from WOWO's AM towers.From Pickerington, Ohio, it's "local" WVKO with the La Mega Spanish-language format.
I use local in quotations because it's 1,600 watts from well northeast of Columbus, near the Licking-Knox county border, and its local contour includes none of its target area at all. The format is simulcast on 107.1 out of Circleville, which hits a few more areas with a substantial Spanish-speaking population but not many.
Outside the area, I remember when WOWO's FM feed was on 103.1. That's been decades ago, and you had to be within 40 or so miles of Fort Wayne to pick up the signal. Maybe 50.
