RADIO HAS BIG
GROWTH IN YEAR
Continued From Page y


oughly practicable for radio tele-
graphic communication and promis-
ing fer radio telephony Repeated
instances OF transmissions thousands
of miles with a few watts of trans
hitting power have been very as
founding to the general public. 1t
has been fouad that waves through
out this frequency range may be
readily directed Ia fairly concen-
treted beams. In this development a
great step has been made toward
the solution of the interference prob
lem.
s.on the question Of future devlop-
ments here are some of things /
anticipate for 1925:
Beam Transmission-dev
Of practical means Of directing waves
in concentrated beams in desired di-
rections. The Use of this system
at lower frequencies heretofore
Adoption Of this system to the reduc-
ton of interference.
tDirectional eception--improye
ments In direction finders. Develop
ment Of very directional receiving
systems. introducing another ele-
ment Of interference reduction.
High Frequencies
Further development and applica-
ton Of the high frequencies. 1000
TO 10000 kilocycles-the utilization
and control OF radio waves at these
frequencies on regular engineering
basis. Increase in knowledge of the
possibilities OF these waves and the
mode Of their propagation.
Radio neutrality-suspicious. Of
means for relaying and rehroadcast-
ing and adoption to various services,
utilizing in particular the higher fre-
Quencies.
Progress in reducing the effects
of fading-improvements in broad
casting. Broadcasting to take more
definite form as a distinct service
as against its initial phases OF nov
city or pastime Higher quality in
the receiving Of broadcasting through
improvements in receiving sets and
through the use OF higher power in
broadcasting stations. Greater availa-
bility Of the past broadcast programs
through interconnection of stations
and through the use of higher power.
z Advances in receiving sets-the
wider use OF sets Of high selectivity
can be expected. While batteries
give such good service as the sup
ply for electron tubes that they are
hard to displace, progress can be
expected on devices Tor using alter
mating current as a tube supply.
Standardization Seen
Radio standardization limina-
ton Of multiplicity of parts by the
radio industry. Standardization of
receiving and transmitting electron
tubes.
Radio Transmission Of Pictures
Improvement of quality and speed
OF transmitted pictures through ef-
forts of numerous investigators and
companies.
Radio Observation-Disclosures of
radio beacon systems for navigation
by sea and air.
General progress on many of the
major problems CT radio technique,
such as various phases OF the inter
ference problem, radio measure
ments, radio wave intensity meas
urement and control, and reduction
of the effects of atmospheric dis
turbances.''
Chief Supervisor Of Radio w. D:
Terrell: The outstanding feature
in radio development during the
year 1924 is the linking together of
several STATIONS by wire and by
radio. making it possible to reach
practically every radio listener in
the United States, putting them in
direct touch with the most impor-
tant events of general public inter
est, such as the political conven-
tons. world series games and adj
dresses by men high In public life. .
Commander J. II. Taylor. Naval
Experiment Laboratory: ST think
the most important development in
1924 was the work done in develop
ing high freqrIencies. and I think
this Development viii continue to be
the most important for some years"
Maj. Louis B. Bender, chief of en-.
cheering and research division,
United States Army Signal Corps:
sI think the major development of
1924 uas fne rrosress made in the
