Devotion to the art of radio has
led Col. E. H. r. Green, Of Round
Hills House, Mass, to conyoke on
his South Dartmouth estate some
of the greatest miracles Of electri-
cal communication for enhancing
the broadcasting programs of this
unique station.
This devotion, marked by in
Vulnerable details of his magnifi-
cent home and grounds is alto
gether different from the ordinary
instinct of a radio fan, no matter
how enthusiastic. 1t has drawn
Colonel Green into an extraordi-
nary series Of adventures with
radio which in turn have led ap-
preciative thousands to know him
closely not as the son Of Hetty
Green, the remarkable railroad
magnate and long time richest
woman of the world, but as a lead
ing exponent of radio to whom the
science is cherished and useful
instrument.
Transfer by Phones.
The very conception of transfer
Of some of New York's best pro.
grams to Round Hills by telephone
is startling to those who do not
share Colonel Green's feeling. He.
not only conceived such a plan, but
had the strength Of purpose to
carry it through.
One Silly night local audiences
heard this unprecedented announce.
ment: This is station WMAF,
South Dartmouth, Mass. You have
been listening to the musical pro
gram of the Capitol Theater, Fifty
first street and Broadway, New
York city," Wonders had to be per-
formed before Colonel Green could
make this simple but striking an
nouncement.
Realizing that New York is the
center of artistic talent, Colonel
Green made arrangements with the
American Telephone and Telegraph
Company whereby programs rem
dered for it's station WEAF should
be transmitted over telephone lines
to Round Hills. Here the speed
and music control the radio trans.
mitter Of WMAF just as If the per.
formers were in the adjoining room.
In the studio of WEAF' is a sensi.
tive micrOphone whose output is
amplified through five stages and
fed to a high-grade telephone cir
cult passing through Hartford,
Providence. and New Bedford. In
each Of these cities the voice cur
rents are twice amplified at tele-
phone repeater stations and the
final four are supplied at Round
Hills, making a total of fifteen
stagles Of amplification. The total
amplification from transmitter to
antenna reaches the enormous fig.
ure of ten billion billion times.
Were 1t not that the energy of
the transmitter is so small and that
much Of the gain" from each stage
is dissipated in the intervening
lines, all the power plants in the
country could not furnish enough
power to operate the last stage Of
application. If the light of
fifty-watt lamp were multiplied by
this amount, it would outshine the
sun itself.
Has Two Great Towers.
From the main hall or the studio
you enter the apparatus room,
where stands the Western Electric
500.watt radio telephone transmitter.
Tiny electric currents bearing the
impress Of the speakers voice and
received through the microphone in
the studio, or from the New York
telephone line, are sent through
four stages Of amplification and
thence to the twin modulator tubes.
Here they control the output Of
two oscillator tubes, thus sending
out to the antenna q high fire.
