PITTSBURGH, Pa. March THE
linking together by short waves OF
hundreds OF stations for the stimuli
taneous broadea sting of-programs Is
the ideal toward which radio broad
casting must strive In order to obtain
the greatest fexibifity of broadcast!
ing service. according TO II. T. Davis
vice president of the Westinghouse
Electric and Manufacturing Company
and Internationally known as the
Father of Broadcasting."
In the use of short waves for re-
laying or boosting, according to Mr..
Davis, lies the future OF broadcasting,
as by proper use of this medium for
interstation linking programs origi-
mating in the centers of the art may
be broadcast simultaneously IN all
parts of the world.
In the past few weeks the short
waves transmitted from KDKA have
been picked UP and repeated by the
British Broadcasting Company In
Great Britain. by the station. oper-
ated by the South German Broad
casting Association in Stuttgart.
Germany; by station JB I'm Johannes
burg. South Africa; by the station
cooperating with the Melbourne Her
aid. in Australia, and by the station
newspaper Of Buepos Aires. Argen-
tina, South America. This interna-
tional repeating is in addition to the
regular repeating of 'KDKA's signals
by its repeating station KFKx at
Hastings, Nebr.
Though the international repeating
OF KDKAs programs recently took
place at different periods and not
simultaneously there is no reason
for their not doing So 49,
Equipped for short Waves.
Stations KYw at Chicago and wBZ
at Sprin gfield, Mass, also operated
by the Westinghouse company, lately
have been equipped TO pick up and
repeat KDKA's short-wave signals.
Thus II is perfectly feasible for
any or all the stations just enumer-
sted to cooperate with KDKA or any
other station using short-wave sig
nails in repeating it's broadcasts, for
a program originating in Pittsburgh
could be heard simultaneously by ra-
dio in Great Britain. Germany. South
Africa, Australia, South America and
all of the radio public within the
range OF stations KDKA, KYW and
WIZ. which include nearly ALI of
North America. One program so
broadcast could be heard in four con-
tinents simultaneously.
With the further development of
short-wave transmitting and receiv-
ing apparatus. any station properly
equipped could pick up and repeat
kDkA's broadcast and broadcast
central would then be initiated Other
short-wave transmitting stations
located at strategic points could also
transmit just as does KDKA. at the
present time and from other chan
nels OF transmission. Then the sta
tions equipped to pick up and repeat
short-wave transmission would have
several transmission channels 10
choose from and thus have different
programs
There is little doubt, according TO
Mr.. Davis, that short waves will
be the linking method OF the future.
Radio waves are the most versatile
and flexible carriers of communica. i.
ton. They are also by far the
cheaper to install and operate. No
great investment is necessary to pro-
vide for their use nor is large
operating force required scattered
throughout the county for their
supervision and operation. The ether
is a broad highway which is never
damaged permanently by inclement
weather. A heavy thunderstorm or
an electrical display, for example, the
northern lights, may tempora rily
make it difficult to transmit, but with
the clearing of the ether the broad
highway is again open. Nature. in
this case, is the repairman.
Within the next few years. Mr..
Davis states, there will be a great
increase in the number of radio sta
tions linked together by short waves.
Radio waves will be used to- stransmit
programs from remote pick up points
TO the broadcasting station and also
for the linking together of broad
casting stations. Ii will do the whole
job
b Worldwide as we'll as national
broadcasting OF programs is in the
offfng and only awaits intensive de-
velopment work with the necessary
installations.
