    I have read that Amelia Earhart was the first civilian pilot to try (and she failed) Bendix RDF equipment on her ill fated flight.  I have also heard that air navigators within the US were issued small directories of the latitude/longitude of powerful AM radio stations, mostly major cities, as an aid to navigation.

    I havent been able to find any example of these directories. Are any NavListers aware of these early RDF directories?

    Have you looked at Ernest K Gann’s ‘Fate is the Hunter’.  You might just find something in there.  If not, it’s a great read in any case. It might also be worth looking at the early chart production of Elrey Borge Jeppesen.  For a fuller history of Ground DF, Airborne DF, and Radio Range Beacons look at Monte Duane Wright's 'Most Probable Position'.
