  • "Under the hood" changes to Mexican listings.
    You may have noticed some rather long lists of "zombie" low-power stations on certain channels. (channel 5, for example) These were the result of the FCC adding some low-power records (not corresponding to any actual station I know of) using facility_id keys WAY outside the range previously used.
    These facility_ids collided with ones I'd assigned to Mexican stations. (non-U.S. stations don't have assigned facility IDs)
    This resulted in MANY Mexican stations matching certain U.S. low-power records and vice-versa.
    I fixed the issue by splitting the Mexican and U.S. data into separate tables. Mexican and U.S. listings are generated separately and then merged after the tables are output. Seems to work.
    I expect to do the same with Canadian data over the next few weeks. For better or worse there are far fewer records in Canada to deal with.
  • TV station coverage maps.
    Due to changes to Google Maps, you may have noticed the links to tower sites and coverage areas have stopped working.
    TV station coverage maps, calculated by the FCC, are now available. Click on the call letters of any U.S. station in the TV Database by state or TV Database by channel listings. A KML file will be downloaded.
    There are two things you can do with this file:
  • Open it in Google Earth.
  • Add it to a personal map in Google Maps. Click the menu (three horizontal bars), then My Maps, then Create Map, then Import, then select the file you saved.
  • Mexican TV listings have been updated. Many thanks to Raymie Humbert for his help.
    HAATs are estimated - the Mexican government releases only antenna height above ground data. Google Earth and the GLOBE database (searchable on the FCC website) make it possible to reasonably estimate HAAT from this data. Using the same methodology with U.S. stations yields results that compare well with FCC records.
    Virtual channel information is subject to change and may not be entirely accurate.
