    Do you have a URL for this list of lat/long for US stations?   I've searched the FCC site and the only thing I can find is something where you have to identify each individual station and after a few clicks you can get its antenna location.   And then it's in NAD27 coordinates!


    ------------------------------------------------------------------------------------------

    If you have to worry about the antenna coordinates being NAD27 instead of NAD83 or WGS84 then you are cutting your navigation too close. And what datum was used for the chart that you are looking at?

    Here is an example of the data from the website I have previously posted.

    http://www.fcc.gov/fcc-bin/amq?list=0&facid=9637

    It is for the KABC in San Francisco. It gives the antenna location in NAD83 but allows you to convert to NAD 27 which results in a shift of only 96 meters.

    Considering the error band when using an RDF it sounds like you are attempting to polish the cannonball.
