The YE Beacon, or YE-ZB System consisted of a coded segmented circle put out as a radio transmision. For example the first 15 degree segment, 0-15 might be coded AA, 15-30 FF etc. The codes were changed daily as it was presumed the Japanese had acess to the frequency and possiby captured equipment.

Range varied with altitude and was generally 40 miles at 4000', 60 miles at 6000' and 80 miles at 8000'.

Apparently it was often used despite otherwise maintainance of radio silence.

Current "vector to base" command works in a similar way, however with 30 degrees segments. I don't quite understand how the transmission sounded like? Was it like you tune the frequency and than hear a voice saying "foxtrot-foxtrot" as "you're in 270-255 segment looking from carrier's mast" or how exactly did it work?
