system of transmitting and receiving
pictures. printed messages and dia-
grams via radio. points out the llilI-
tary value of this new phase of radio.
One of the first aims back of the
long efforts of experts to transmit in
telligence via the ether, he says, was
to provide military authorities with
the ability to send autograph copies
of messages and diagrams so as to
insure prompt. accurate and reliable
confirmation Of orders
Future Military Use.
Modern, commercial radio picture
Transmitting and receiving apparatus
is readily adaptable to military and
naval use especially in time of war.
II is understood. In this connection 1t
will probably extend the vision of the
commanderS.in-chie and their sub.
commanders so as to cover wide fields
of operation on both land and sea.
With this radio apparatus carried
aloft by aircraft it is prohable that i'll
future battles aerial views of the
maneuvers, showing the several ships
of units in action. may be placed be-
fore the general staff within u few
minutes time. No more will staff Off.
GERS have to imagine the positions of
their units with relation to the enemy,
Sketches and diagrams drawn from
over the lines. or photographs of their
actual positions. will be available con.
tinually for careful study and analy-
sis.
Discussing some of the military adj
Vantages of visual and photographic
reproduction via radio. Capt. Ranger
SAYS that there is nothing to prevent
the carrying of this plan as far as
relayed dots and daSheS of radio have
been extended. 1t makes possible the
transmission of dispatches to a group
of receiving points simultaneously,
and as the receiver is much less COM
plicated than the transmitter it makes
the problem Of handling receivers in
the field less difficult. The whole
photoradio equipment is now no more
complex than was the original radio
equipment used by the Signal Corps.
1t is expected that improvements Will
make it possible for two men to carry
all but the largest equipment neces-
sary for the transmission and recep.
ton of photoradio communications.
Service Guaranteed.
The perfected military apparatus.
the inventor believes. will combine the
personal feature Of the radiotelephone,
which eliminates the need for an eX.
pert operator, and the radiotelegra ph,
which inSures a copy of all messages
sent and received. In this connection
he says: THE officer at the trans
mitter may write out freely his de-
sired message and incorporate in it
such diagrams and sketches a 8 he may
desire. Without the necessity of in
depreciation by any intermediate oper-
ators. the receiving office has before
him an autographic duplicate of this
original message. with the assurance
that what he sees was sent
Other features Of the photoradio
methods Of communication are that
modern methods of ciphering are ap-
plicable and that as the Transmitting
method is dependent upon synchro-
nism this feature may be applied to
add further secrecy without the need
of decipherinS.
