NEW YORK, April 19.-Aboard the
steamship Leyiathan, flagship of the
United States lines, and largest ves-
sci afloat, when she recently sailed
from New York to European ports,
went the most modern and best
equipped radio station in the world.
New equipment installed aboard the
great liner gives her a radio outfit
that represents the last word in
efficiency. A staff of eight operators
headed by Chief Radio officer L. n.
Pickerill, none of whom has had
less than ten years experience. and
two messengers are included in the
personnel necessary for the handling
of the radio equipment. 1t is the
largest radio personnel on any ocean
liner.
From the time the Leviathan leaves
her pier until her return duplex
watches are maintained at all times
in the radio room to insure the recep-
tion and transmission of traffic with
out delay. This was made possible
by the installation OF additional re-
ceirinE equipment for tuning in sta
tlonS on long and short waves stimuli
taneouSly, combined with the ability
70 transmit and receive messages on
different wave lengths at the same
time. Five antennae are uSed-three
Tor transmission and two for recep-
tion.
transmitting Installation.
The transmitting installation in
ciudeS one hiEh-powered tube trans
1nitter which is used on wave lengths
of 1900. 1885, 2.100 and 2,400 meters
With this tranSmitter communication
may be established with shore re-
sardlesS o. Ine sntps position UI I.e
Atlantic.
In addition to the high-powered
tube transmitter. one-kilowatt Radio
Corporati ton duplex telephone and
telegraph tranSmitter and one two
kiiowatt Navy standard spark set
make transmission on shorter waves
possible while the high-powered trans
nitter is being operated.
1t can be readily seen that every
Provision has been made for the
safety of passengers when complete
Transmitting and receiving apparatus
was installed in two motor lifeboats
30 that communication may be es
tablished after they are launched.
Two onehalf kilowatt transmitters
and two receiving sets equipped with
Iwo steps OF amplification have made
this possible.
The receiving equipment in the
radio station consists of the follow
ing:
One Radio Corporation duplex tele-
phone receiver.
One special reflector receiver, en-
abling the operation of two tele-
graph tranSmitteTS and receivers Si-
multaneouSly on GOO to 5000 meter
wave lengths.
One Navy type long-wave receiver,
1000 to $500 meters. for listening
IN on high powered government sta
tionS
One Radio Corporate n receiver 500
to 1000 meters
Automatic break-f in systems for
telegraph receivers have been in
stalled to make reception of signals
possible as soon as the operator re-
leases the key.
Remote Control.
Automatic remote control enables
the operator to start generators for
ira smisSion with the least possible
effort.
Loud speaking apparatus can be
placed on the stage and various parts
OF the vessel connected direct with
the radio room for the reception of
radio broadcast programs.
Auxiliary storage batteries have
been, installed so that communication
may be established in case power sup
ply from the engine room has been
cut off
Sending of money by telegraph has
been made possible through the
Farmers Loan and Trust Company,
which main tafnS a bank on board
in addition to complete radio equip
ment some of the lifeboats have been
equipped with submarine signal equip
ment, which is used for Indicating the
direction in which lifeboat may be
located
IL can be readily seen that no ef-
fort has been spared in providing for
the safety and convenience of those
