(This one gives real Longley-Rice maps for most US FM stations, but not for AM.
One problem with radio-locator maps: I don't think they give any indication of how stations on the same frequency or nearby frequencies affect signal ranges.
It's just a crude database for entertainment purposes, not a tool for determining co-or adjacent interference instances.
And only the innermost contour on radio-locator even comes close to showing the consumer (average listener) clear, reliable coverage area. For AM, it does not adequately reflect variants in ground conductivity. For FM, it fails to compensate for much of the terrain blockages and irregularities and shadow areas or multipath zones.
But yes, those are useful to get a rough idea of coverage but one would not "bet money" on an ad buy or a station purchase based on that!
FMFool can provide adjacent-channel, co-channel interference information for a certain location / address. But it's not a map.
FCCData through RecNet is a much better resource than Radio-Locator. Haven’t been on the latter site for years when I found the former. Maps for AM, FM and TV are provided for the US, as well as Canada, Mexico, the UK and a few other countries (however, there are no AM maps for Canada).
You're right - I've checked it against some "known" stations (i.e. I know where I lose the signal!) and the FCCdata coverage maps are pretty damn accurate. Radio-Locator can be far too optimistic.
I tried them all and this is the best by far, you can even click on a more indepth coverage map, with many contours, it even shows how many bays an FM signal utilizes really neat....https://fccdata.org/
These are certainly not accurate at all, but they're loads of fun. For AM:

David's right about Rabbitears.com
Good maps of FM radio contours and dead spots, due to hills, mountains, valleys, etc.

So what is the starting query page at RabbitEars to make scatter plot be generated for any station, FM or TV?
For FCC-style contours I use the API : Contour Demo - FCC Contour API (boring)
Clearly RabbitEars is more sophisticated....
