[Moon-net] New radio waves

[Earl (Jim) Shaffer, WB9UWA]

Hi Leif.

Starting your celebrating a little, early, aren't you?
Wouldn't these rays have to originate from the other end
of a worm hole? Really though. I have no idea. I tried to
follow along and thought they were trying to describe
antenna that could change its direction of heading without
physically moving it.

73, Jim Shaffer, WB9UWA.
Merry Christamas to all !
