May, 191 THE ELECTRICAL EXPERIMENTER 29<br />
WIRELESS OUTFIT ON MOVING<br />
VAN TRACES MESSAGE.<br />
After a search of three months for an <strong>The</strong> accompaiiyinji,' photographs show the<br />
amateur wireless operator who sent out long distance, undamped wave receiving<br />
unsigned "SOS" messages in the neighbor- set owned liy Marvcy L. Gamer, <strong>Electrical</strong><br />
hood of New York and caused great an- Engineer of Omalia, Xeb., with which the<br />
tioyance to the New York iVavy<br />
Yard and navy vessels the federal<br />
authorities recently arrested<br />
William F. l-!ckolT, sixteen years<br />
old, who had a wireless station<br />
on the roof of his home in<br />
Brooklyn.<br />
When the messages were first<br />
heard there were reports in shipping<br />
circles of submarines operating<br />
near New ^'ork. After several<br />
of these calls stations nearby<br />
recognized them as the work<br />
of an amateur. <strong>The</strong> .New York<br />
Herald's wireless station worked<br />
with the operators at the New<br />
York Navy ^'ard in an efTort to<br />
locate the station. <strong>The</strong> log at the<br />
Herald's wireless station shows<br />
that these distress messages were<br />
sent at all hours of the night.<br />
<strong>The</strong> mysterious operator used<br />
the calls of the Navy Yard and<br />
naval vessels.<br />
Louis K. Krumm, chief radio<br />
inspector of the Department of<br />
Commerce, engaged a moving<br />
van and installed in it a small<br />
wireless set which could detect<br />
messages within the radius of<br />
only a block. Operators had<br />
traced the messages to Brooklyn,<br />
and, with the moving van, Mr.<br />
Krumm went about Brooklyn until<br />
he arrived in front of the<br />
Court Street house.<br />
It is alleged that Eckoff used<br />
a L'nited States code signal on<br />
the night of Januarv twenty-first<br />
last, sending an "SOS" call which<br />
which was picked up by the Herald station<br />
and relayed to t e super-dreadnought Arizona<br />
at the New York yard.<br />
Eckoff was arraigned before United<br />
States Commissioner Louis Bick and admitted<br />
he had been sending messages, but<br />
asserted that if he had used the United<br />
States code he had done it innocently, for<br />
he did not understand the code thoroly<br />
enough to commit a nuisance.<br />
<strong>The</strong> efficiency of such portable radio stations<br />
has been markedly improved in recent<br />
years by tlie advent of spiral aerials.<br />

Some of the stations in the United<br />

WGG (Tuckerton), when the Goldschmit<br />
alternator is used, come in so loud that<br />
the signals can be transmitted over the<br />

Uncle Sam's Radio Inspectors Find it Difficult at Times to Accurately Locate and Run Down<br />
Stations which Disobey the Law, but a Radio Set and Aerial Erected Inside an Auto Van<br />
Helped to Solve One Problem.<br />
<strong>The</strong> amplification feature is obtained by<br />
the use of inductances and capacity in the<br />
wing circuit of an Audiotron, then a<br />
further amplification with two ordinary<br />
Audions and their respective coils and circuits<br />
as well as a micro-phone arrangement<br />
leading to the recording machine.<br />
<strong>The</strong> large loose coupler was designed to<br />
tune to wave lengths up to 15,000 meters<br />
when used with this particular aerial system.<br />
SECRETARY OF COMMERCE<br />
SUSPENDS ISSUING OF LICENSES<br />
Issuing of licenses for amateur wireless<br />
apparatus was suspended on March twentyseventh<br />
by Secretary Redfield. Virtually<br />
none of the amateurs have sending equipment,<br />
so the military and naval authorities<br />
have not considered them a source of immediate<br />
that no<br />
present.<br />
danger, but Mr. Redfield decided<br />
more should be licensed for the<br />
Sending wireless plants are under<br />
the strictest possible surveillance now. and<br />
if a state of war is declared efforts will be<br />
made to locate apparatus of every description.<br />
Many of the amateurs now licensed by<br />
the Government belong to the Navv radio<br />
reserve and will be called upon to perform<br />
certain duties in war.<br />
TO TEACH GIRLS WIRELESS<br />
At a meeting of the National Special<br />
Aid Society recently, a school offering a<br />
course in wireless telegraphy for young<br />
women was organized. Instruction will<br />
be given at the society's headquarters, 259<br />
Fifth .\ venue. New York Citv.<br />
Miss Daisy Florence, chairman of the<br />
new branch, urges that all voung women<br />
who would like to take up this" class of<br />
work send in their applications. E. T.<br />
Bicak, a New \ovk radio expert, has been<br />
retained and will have entire charge of the<br />
classes. This new department, the society<br />
says, is the first of the kind.
