I can remember early WAC charts having occasional hi powered AM stations printed on them for such use.

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?
I did find these two references but both are much later.
- Introduction to Radio Direction Finding, US Army Intelligence Center, August 1999 (attached, see section of RDF and lines of position)
- Naval Oceanographic Ollice publication H.O. 205, “Radio Navigational Aids"
