AS CURB ON RADIO
Transmission of Facsimile Is
Also Called Handicap
to Short Wave Uses.

ne WlQe swain cut III the ether by
high frequency transmission of fac
sinlile and the newly developing televi-
sion was cited among the limitations
upon extension Of the uses Of short
wave channels during the course of the
hearings on the Short-wave problem
which have just been concluded by the
Federal Radio Commission. That there
are physical limitations beyond which
even radios scientific wonder men"
cannot go was emphasized repeatedly
at the hearings
The communication companies al
ready operating with short waves were
not alone in cautionilg the commission
10 proceed slowly il conceding channel
assignments in the lower end of the
radio spectrum to the multitudilous
commercial interests seeking the light
10 erect stations TO carry on communi-
cations by radio. Eminent scientific
men like Dr.. J. H. Dellinger OF the
Bureau Of Standards. Capt. S. c.
Hooper Of the Navy. Prof. c. NJ Jansky
OF the University of Minnesota. Frank
V. L Hogan, the New York consulting
engineer. and K B. Warner. secretary
of the American Radio Relay League.
spoke of the definite limitations in pres
ent-day development of short waves.
DR.. Dellinger'S estimate was that 1000
channels might be available below 200
meters. with an average frequency Sepa-
ration of kilecycleS, but he pointed
out that the International Radiotele-
graph Convention defining the bands
for various services would become ef-
fective in 1929 Col Manton Davis
the Radio Corporation of America
counsel. urging that only organizations
with adequate facilities TO furnish serv-
ice TO the public be licensed 10 use the
short waves estimated something under
l,50o channels which. after division
with the rest of the world and consider
alton o. the limited number Of waves
usable for long-6lstance communica-
non. would be pared down 10 around
110. This was about the figure arrived
al by Capt. Hooper.
Dr.. Deilinger suggested that assign
mentS 10 stations close together geo.
graphlcally. better frequency control of
transmitting stations and the develop
n1ent OF more highly selective short
wave receivers might conceivablv re-
cuce the separation between channels
ana open up more wave lengths for
use. These propositions were taken up
oY d., A. NJ. Goldsmith. the r. c A
engineer. who added that directive
transmission may also help. but who
took the position that the science has
not yet developed far enough to use
more than 10 frequencies. It would
De possible 10 draw UP a "theorctic
scale, Of 100000 channels. but these
would be as practicable as having two
automocSles each five feet wide try to
pass each other on a i0-foot road" ac-
corcing 10 Dr.. Goldsmith.
