Was macht denn die Deutsche Welle da leise in Deutsch auf 7705 kHz? ...

USA VOA Greenville - Fifty Years of Shortwave to the World.
LBA_Antenna Turns, by Chris Horne.
Tranquility Base, here. The Eagle has landed. The Voice of America had the
world's largest audience ever when it reported in 46 languages man landing
on the Moon. It earned trust when it reported on Watergate and the anti-

some large VOA broadcasting facilities. The federal government would like
to close VOA site B in Greenville, NC. I hope they choose not to for some
several reasons.
Recently, I toured VOA Site B and observed first hand both the magnitude
of the transmitting equipment and the value its broadcasting can add to
the international community. The day I arrived at VOA-B, the hundreds of
acres of tall expansive antennas made you feel you were entering another
planet. The father of wireless, Guglielmo Marconi, would be proud to see
such a place full of great engineering and information for the world. Many
wire antennas meshed together to form a tall wide curtain were supported
by tall 300 feet towers. Each tower is fed by elevated transmission line
(1 inch conducting pipes) 15 feet off the ground. Once inside the
transmitting facility, the same degree of largeness is apparent by several
"truck size" transmitters...
