[Milsurplus] Over-ocean RDF use?

[Hue Miller]

I know some of you can answer this from actual
experience. I would appreciate very much, your input.

If i am flying over the Pacific, leaving Hawaii, for
example, and my LF/MF RDF is tuned to a Hawaii
10 kw broadcast station, in daylight, how far will
out will i have a good signal for DFing? Or strong
enough for good listening?

Any different at sea level? In a ship, how far out
could i hear this same broadcast station, around
10:00, well after sunrise, in daylight?

Assuming 1940s radio equipment ( which is not to
say poor equipment! )
Thanks- Hue Miller
