Lizard mentioned Leonard ha ha that sounds funny... i laughed.... then i went to lostpedia and clicked around.

First i dont think that any govt is listeneing in that area anymore. I Think Leonard was stantioned in the south pacific 16 years ago and its possible they had reason to be there becase of america's ability to get into war. anywho... its also possible that the signal is soo archaeic and odd that its picked up as static or interference, rather than a cylcing progression by our modern instruments.

OR They know its there and they are in on it... ( dont ask me who THEY are)

Henry Gale says they have contact or the like, with the outside world. so maybe they dont need to look for the signal.
