Possibilities of Radio Today
and Tomorrow Told by Expert

Transcribed on message blanks by
operators.
By this method. elimination of
the human relay at the receiving
station has been effected, an OBJ
vious saving in time and an aid to
accuracy. OF still more recent
date is the new method devised by
which two or more radio signals
may simultaneously be transferred
to the central operating office
over a single wire, and the con-
current development of devices
which make 1t possible to receive
signals from four European sta
lions on ,One receiving antenna
without mutual interference.
Only a few high spots" have
been touched il the foregoing ref
erence to the radio system exist
ing in the present day; it includes,
of course q commercial Organiza-
ton represented in principal cities
by branch offices, and d messen-
ger service adequate to take care
of message traffic-a traffic which
has grown within the past two
years to something more than 90
per cent of the total business
handled by II cables connecting
the old world with the new.
Radio Corporation OF America
The Radio Corporation of Ameri-
ca was formed as the result of an
appeal. Crom government sources
calling UPON the patriotism and
vision of the great electrical in
dustries in the United States to es-
tablish an American-owned, Oper-
ated. and controlled radio COM
municauon company, powerful
enough to meet the competition of
the radio interests of other nations
and to develop the new art to the
greatest possible service OF the
American people and the Ameri-
can government.
The supreme inventive genius
of the country, the greatest organ
izing ability, and the most power
full resources were placed at the
service of the new art, with the re-
suit that radio has made greater
strides in the past two years, than
it had in the ten years previously.
The Radio Corporation of Ameri-
ca now enjoys the benefits of the
highly developed manufacturing
and research organizations of the
General Electric company, Ameri
can Telephone and Telegraph COM
pany, Wireless Specially Appar
atus company and the Westing
house Electric & Manufacturing
company together with its subsi-
diary, the International Radio
Telegraph company.

MARCONI WILL BE
AT BIG WIRELESS
SHOW IN CHICAGO

The Chicago radio show to be
held in the Coliseum in October
promises to be an elaborate affair,
and, according to committees in
charge, will substantiate its sub
title as an international and annual
exhibition.
One of the features of the show
will be the presence of Signor Mar
conf. who needs no introduction TO
wireless fans. Wilbur Williams,
who has been touring Europe in the
interest of the exposition, recently
secured a promise from Marconi
that he would include the Chicago
dates in his calendar and would
undoubtedly be present for an en-
tire day during the exposition per-
iod.
Mr.. Williams reports that the for
eign manufacturers are keenly in
terested in the rapid developments
in the American radio and will re-
turn to America with an interesting
list of prospective exhibitors.
The foreign consuls. located in
Chicago, are showing a keen inter-
est in the forthcoming event, espe-
cially those of Great Britain,
France, Italy and Switzerland.

pOration of America
TransOceanic Radio.


The vastness of this system to-
day is litIle appreciated by the
general public a score of nations
in Europe and Asia are in regular
radio telegraph communication
with America and millions OF
words are exchanged in u straight
commercial message business op-
Grated day and night.
A great network of high power
stations is required to maintain
the world wide system of the Ra-
dio Corporation of America; pow
erful transmitters are located in
Massachusetts, Long Island, New
Jersey, California and Hawaii.
South America, too, will soon be
adequately provided Tor Ind al
ready, America is conceded . the
foremost position in the matter OF
commercial radio communications.
The corr respondent stations abroad
are located in the important com
munication centerS OF Europe,
Hawaii and in Japan.
In the accomplishment of the re
liable trans-oCean service which
prev ais today, radio telegraphy has
made some wonderful strides IN
technical development. The old
time spark station has made way
for a newer type transmitting sig
nails carried on a continuous wave,
through which speed and accuracy
have been increased and interior
ence reduced &c a minimum. This
great improvement is largely due
to the development of the AleXan-
Ciersop alternator, radio ere
guency machine which gives an
output of 200 kilowatts, and which
is produced by the General Elec-
trio company. More than a dozen
of these machines have been in
stalled in American stations.
Marked increase in the radiatlng
efficiency of these transmitting
stations has come, too, through
improved design and application
of the multiple tuned antenna. And
of equal importance is the cores
ponding development of long-dis-
lance reception, whereby MESA ges

from the. receiving station over
land wires direct to single Of

RADIO INSURES
SAFE LANDING
OF AIRPLANES
Aids Aircraft in Finding Place to
Alight at Night or in Dense
Fog.

Airplanes in the future will be
able to find their landing stations
at night and in the densest fogs. be-
cause Of radio.
Experts of the e. S. bureau of
standards have adopted a method
by which pilots nearing their des-
tinations will be able to tell by ra-
dio exactly where they are in re-
lation to the landing stations. The
new radio system makes the degree
of safety in landing much higher
than ever.
Radio direction finders and 9th
er radio devices have been in use
for some time to assist airpIanes to
land during the night, during fog
and at other times of poor visible
ity. All these give the direction of
the landing field, but do not give
accurate information as to its dis
lance when the plane is approach
ing
Several new methods were tried
before the use of radio was under
taken. On experimenting with a
special airplane it was found that
the radio system gave the pilot def
mite information as to where he
was in relation to the landing sta
ton
This radio landing signal con-
sists of two horizontal coils placed
one above the other near the
ground. The currents in these coils
flow in opposite directions at a
fairly high radio frequency.
By various tests it has been as
certained that the signals radiated
from the two coils are strongest for
an airplane flying parallel to the
ground, whenever the machine is
inside a comparatively small ring
shaped area directly above the
landing field.
Operation.
The strongest signals are received
when the line joining the airplane
to the coils is about 80 degrees from
the vertical. Then the signals
grow weaker as the airplane flies
toward the spot directly above the
transmitting coils. There, the sig
nal vanishes.
AS the airpIane flies away from
this point, the signals become
stronger until the plane reaches the
30-degree line at the other end of
the ring. Flying farther the pilot
finds the signals vanish almost as
soon as he has left this ring.

growing rapidly.
There is no reason why similar
groups should not be organized
throughout the country.
For disciplinary reasons it is sug-
gested that the corps be formed on
a military basis-with some dis
tinctive uniform to give the group
a solidarity.
1t will help make them snappy.

York the boys won many prizes for

TOSEND RADIO
MESSAGES IN
SECRECY SOON
Engineers Working on Several
Methods; Would Be Great
Accomplishment.

Eventually means will be found
whereby radio messages will be
sent in comparative secrecy.
Many steps tending toward this
end have already been announced.
But the chief drawback to all pres
ent methods has been the expense
Of equipment.
There are two methods of insur-
ing secrecy in the transmission of
radio messages.
The frst-the one which is most
likely to be used in the near future
consists in broadcasting a type
of wave which cannot be translat-
ed by the receiver unless that in
strument has been so constructed
as to contain the key.
Distortion Method.
In installations of this type, the
radio wave is produced in the usual
manner. The voice which is to be
carried by the wave is thrown upon
1t. Then the whole is distorted IN
way known only to the receiver.
Upon arriving at the distant sta
ton, the receiver signal is again
distorted IN a manner exactly
equal ana opposite to the first dis
tortion, with the result that the
telephone signal is again intelli-
giblc.
This type of secrecy has the
drawback that, in addition to go
ing directly to that one person for
whom it is intended, it also spreads
in every direction, and acts as in
reference except for its own sta
ton.
A second method of sending "a
do messages in secrecy and one
upon which a great deal of effort
has been spent, is that of directing
the radio wave along a given path
so that the transmitted energy trav-
els along that path alone. The
message is capable of reception
only by stations which are in that
path.
Tried Out.
This would reduce TO a great ex-
tent the possibility of radio teIe-
phone conversations being inter
cepted by those for whom they were
not intended.
Transmitting systems of this type
were used by our eXpeditionary
forces on the western front with
considerable success. 1t should be
but a few years before the high
powered stations which plan to pro-
vide nter-continental radio tele-
phone service will be utilizing sys-
tens of this sort.
A combination of these two sys-
tens would insure practically COM
plete secrecy in radio communica-
ton
Some such combination undoubt-
eddy will be perfected by radio en-
gineers as simpler methods and
easier ways of performing the com
plicated functions of a radio trans
mitter and receiver are discovered.

r. NJ, Aledo-I have several re-
ceivers taken from ordinary tele-
phones. Can l use them on a wire
less set?
1t is impractical to use receivers
of such low resistance on a radio
set.
What is the difference between a
radio and a wireless?
The teams radio and wireless are
alike in meaning. Radio is the
later and more technical sounding
name applied to the same thing.
l have a DL-35 coil which was
sold to me for getting music from
any Of the broadcasting stations.
Shouldn't l have a larger coil,
about a 800, to receive from Pitts
burgh?
If you want to receive the broad
casting stations, the So coil is the
correct size. as all OF the broad
casting stations send on the same
wave length. Do not forget that
the wave length has nothing to do
with the distance of the station, but
is simply a technical term denoting
the frequency of the vibrations.
What is the proper voltage for
the plate of a radiotron bulb?
The correct plate voltage for the
detector tube is between IS and
2215 volts, for the amplffier tube
from 221a to 100 volts. Forty-five
volts is generally used on the am
plifier.

WOMAN SEEKS OFFICE.
English Physician Wants to Be Health
Minister.


There is a good deal of speculation
as to whether DR.. Ethel Bentham viii
achieve her openly expressed desire
and become the British minister OF
health, says a London dispatch.
She has the backing of the women
generally and is known to be capable
and earnest. Ii is not conceivable that
the appointment may be given to her
as an inducement to the women to
jump in and play their part in poll
tics--somcthing which to the mems
great surprise they do not seem in
clined to do, despite the militant cam
paign which they waged for years be-
fore they got the vote.
DR.. Bentham says that by far the
greater portion of bad health in Eng
land is due to none Of the popularity
ascribed causes for it, such as drink
and dirt, but chiefly to bad housing. If
she ever gets the job Of head of the
health ministry she certainly will give
tremendous thought to this one prob
lem.
Before the war" she says, housing
conditions throughout England had
become so bad as to be scandalous,
not only in the cities, but also in the
rural districts and since the war the
overcrowding, due to lack Of new con-
struction, has made them far worse
than they ever were before.
"All maxims Of health are inopera-
bic in such housing conditions rs are
commonly the result Of overcrowdinS
and bad old construction.
"In the section of London which
represent in parliament, the average
family allotment cannot be more than
two rooms and hundreds hare but one.
This can be good for neither health
nor morals.
at doesn't matter in the least wheth-
er we have the money to correct this
evil. With money or without it, it
must be corrected. If debt is justifia-
blc for anything on earth it is juctiti-
able for this
