'Meaconing' (not 'meakoning') is nothing to do with the Mekong Delta in Vietnam. Neither does it have anything to do with the 'Mekon' of Dan Dare fame.
The word is derived from 'Masking beacon'.
It was developed during WW2 by the British Post Office, to interfere with German navigation systems. Also used during the Cold War to try to entice NATO aircraft to enter Eastern Bloc airspace.
You beat me to it, ZH875!
