As I remember it, the Lady Be Good had no ADF, which is Automatic Direction Finder. It 
had a "Football" loop and a receiver (like the BC-453) with a loop connection which 
could be used to easily determine a bearing to a known transmitter, like an NDB

Also, as I remember reading, Soluch did not have an ADF either, nor did that British-
manned station which gave them a bearing.

These were strictly manually manned DF stations, or HuffDuff (HFDF) as the Brits called 
them.

None of these systems had a way to resolve the 180 degree ambiguity on a single 
bearing to an unknown station: there had to be at least two bearings to known stations 
in order to triangulate a position.

I also remember reading that at least one person had heard what later turned out to be 
LBG pass over an airfield or radio station.

Although "sense" antennas coupled to loops at a single receiver were known and used 
at the time, as far as I know, no aircraft carried that type of gear that early in WWII.

But no ADF, as far as I know that early on.

I'm not even sure the early Bendix MN-26 was a true ADF, and I also don't know if LBG 
carried one in any case.
