The first commercial Short-wave,
low-powered tranSoceanic radio sta
ton has been licensed. indicating the
recognition Of this means of COM
munication by the commercial radio
interest, following the successful
long distance experiments of en-
gineers and amateurs.
Station WGH of the Radio Cor
poration of America at Tuckerton,
y. j., has been licensed Professionally
to operate on 90, SO, 81. 100 and 1913
meters by the Department of Com
merce. With this new transmitter
rated at 20 XIV, the corporation ex-
poets to establish auxiliary long
distance commercial circuits to
Buenos Aires, Berlin and Paris, in
addition to their seven high powered
| long wave circuits operated from
New York City.
When compared with the power
and wave length of the main trans
mitter WGG, at Tuckerton, which
are, respectively. 200 NV. and 5000
meters, the radical step is obvious;
only onetenth the power is to he
used. 1t is possible, if this circuit
operates successfully. that short
wave, low-power stations may even
tually supercede the expensive high
powered stations previously believed
cults.
The range of WGG is approximate
ly $500 miles, carrying to Buenos
Aires, and if WGH is to establish
such circuit it must also function
over great distances, at least at night,
when the peak of the traffic of the
corporations radio central station in
New York is reached.
Radio experts believe this CONNER
cial step is especially significant and
that, with the development of short
wave tranSmitters and receivers,
sufficient short-wave channels will be
found for additional circuits of this
type. Within the band 80 to 103
meters the assigned wave lengths
| may be placed much closer together
than within longer wave bands
Whether the corporation also will re-
ceive on short waves is not known
but 1T is pointed out that it will
proba bly, have no trouble in span
ming the Atlantic or reaching South
America, receiving on the longer
wave lengths until foreign short
wave stations are established. Dr.
| Taylor of the Naval Radio Research
| Laboratory stated recently that with
his L y XIV. short-wave transmitter
at Bellevue, d. c.. he has been heard
| in Argentina, Chile and Brazil. West
lnghouse experiments have been quite
i successful in short-wave transmission
and abroad considerable progress
| has been made. The whole radio in
| dustry is watching the practical op-
Grafton or the type of station the
r. c. A. is about to open.
! This new transmitter will be coupled
INTO the radio net operated from New
York City. short time ago the
writer visited 64 Broad street. the
| so-called Radio center of the world. "
1t is probably justly named, since
; under this single roof, direct COM
! munications to seven distant coun-
tries are transmitted simultaneously,
! while radiograms from 13 foreign
| stations may be copied at the same
| instant. No other station is capable
of handling such heavy traffic 1T
is constant fight against time"
Supervisor W. A. Winterhottom de-
, clared, describing the 24-hour daily
| operation.
| OF course. the apparatus is operat-
! ed by remote control, land lines lead
| ing to the seven suburban transmit
| ters. and, similarly, wires bring in
the messages picked up at central re-
| ceiving stations at Riverhead, Long
| Island.
Within the operation room there
| are two banks of desks. At seven of
| them, men operate automatic type
| writer keyboards, which perforate a
| tape with holes corresponding to let
ters, the tape then being fed into the
| transmitting apparatus. At the other
| desks a dozen or 3 men are receiving
| messages from as many points; they
| hear the code from saunders. but at
| the same time the messages are
recorded on paper tapes by a waving
| ink line. which designates the dots
| nd dashes of the code, enabling them
| to read both by ear and eye. Some
times the messages come in SO fast
