Format and edit filter validation	{{Constraint:Single value}} with some exceptions: Stations occasionally are allowed to directly change the city of license; or occasionally a station "swaps" with another station and the Wikipedia article follows the cultural identity (to a new frequency and possibly city of license) rather than the station facility (same frequency/city with new programming). Values should be unique within a start-end period though. {{Constraint:Value type|class=Q2221906|relation=instance}}: some location items don't match this yet, but that's a problem with the location item, not the station item
Source	U.S. FCC databases (online and updated frequently) have official city, state, and country for this property in the U.S., and sometimes-lagging last-notified data for Canada and Mexico; similar official Canadian and Mexican lists exist (though, last I checked, Mexico's official publication was PDF) (note: this information should be moved to a property statement; use property source website for the property (P1896))
Robot and gadget jobs	A bot or gadget could find the correct Wikidata item: Scan the station's English Wikipedia article for a "city" parameter in the infobox. Find the link's Wikidata item (which is presumably a location). Compare the location's English Wikipedia article name and/or Wikidata labels to the proper government database. If the name of the city/community matches the name in the government database, it's validated: Add this property to the station's item on Wikidata. If a city/community name exists in a Wikipedia infobox or this property on Wikidata, and its label does not match the government database, something is inconsistent: Log it. This test can be repeated on any item at any time.
