Transatlantic
Broadcasting
Now Looms Up
Successful Test by Newark
With London Has Opened
Up Promising Possibility
for This i'm Near Future
Observation-Disclosures
Time Coming When Impor-
tant World Events Will
Be Broadcasted by Radio

London successfully heard music radi-
ated from Newark, N. j., forecasts the
wonderful possibilities which are the
immediate future Of radio broadcasting.
These are still further emphasized by
the successful broadcasting Of the
worlds series baseball games direct
from the Polo Grounds.
The remarkable results obtained by
the enterprise Of Tho Tribune in CO.
operation with the Westinghouse Elec-
trio and Manufacturing Company and
the Western Union Telegraph Com
pany in broadcasting the Yankees
Giants games for the first time in the
history of our national sport have sur
passed all expectations. More than
100000 people have listened daily to
THbune's nationally known sport ex-
pert. The cries Of the crowd, the
music and the announcements Of the
umpires have all been clearly radiated
direct from the grounds through WIZ
over radius of 800 miles.
According to the report cabled over
by Gordon Selfridge, upon whose store
in London the receiving set was in
stalled, the actual reception Of the mu-
sio and singing was marred somewhat
by; interference from wireless telegraph
coast. This, however, was to be ex-
pected in the initial test-the remark
able thing being that music should
have been heard in view of the small
amount of power used at the broadcast
ing station.
The test is far more wonderful than
was the special test conducted across
the Atlantic Ocean last December by
the amateurs of this country. Although
the amateurs used no greater power
than was used by the Newark station
their tests consisted of telegraph mes
sages transmitted in dots and dashes.
Telephone Covers Less Distance
To understand the difference one
must understand that with dots and
dashes a steady current of unvarying
power and amplitude is being radiated
from the transmitting station. In the
case Of Tadio-telephone transmitting
station, however, the power radiated
has to conform to the varying ampli-
tude of the human voice, and conse-
quently the average strength of the
signals radiated is really no greater
than the weakest tone in any partic-
ular word, or musical note.
it can be still better understood If
we take for granted a fact that has
been daily demonstrated by actual ex-
perience, namely, that radio telephone
can cover only onefourth of the dis
tance that can be covered by radio
telegraph with equal power. In fact,
If the same transmitting station is
used for both purposes, it will cover
four times the distance when used as a
telegraph station. The test of Sunday
therefore is indeed remarkable
From the point of public utility, the
success attained by this initial per-
formance opens up new field Of vast
potentialities in international associa-
tion. 1t gives promise in the near fu-
ture of broadcasting all important
world events over the European and
American continents simultaneously.
International Broadcast Soon
An idea of the importance Of this
can be gained by considering the pres
ent Near Eastern crisis. The time will
come in the near future when the de-
bates of the British Parliament, the
french Chamber of Deputies and our
own Congress will be broadcast from
ting stations and picked up and re-
rediated by other radio-phone stations
In different parts of the civilized world.
There is no reason in the world whv
these broadcasts should not be trans
n1ttted across the Atlantic Ocean. The
recent development of high power
vacuum tubes has opened up the way
Tor this possibility, and it is only a
question of time before these tubes

dltlons for testing purposes.
