How can you be so certain the station isn't operating at full power? Do have any proof?
as long as there isnt a -LP or -CA after the legal ID (or the ID has numbers in it), its full power.
Even if the station isnt broadcasting at full power, its still classified as full power. As an example, the below (WMQF Fox Marquette, MI) is only broadcasting at 500kw when "full power" UHF is 5000kw. Yet the FCC calls this station Full Power
