So, do you think the radio stations also did that during WWII? I'd hate to
think that there were German subs getting lost at Coney Island!

Commercial radio stations came on the air in 1921 (IIRC) and were required to
give their call sign, frequency and city every ten minutes specificly to aid
ships at sea in navigation. This radio required lasted (I believe) into the
1980's by which time it was more than thoroughly obsolete.
