Gus messages hat are filling the air
day and night. Only one precau-
tionary measure should be taken be-
fore inaugurating the new receiving
station. That Is to get the approval
of the fire underwriterr, tina: the in
stallation is safe fiom danger by
lightning Or fire.
Sending messages by radio has
been under government control ever
since the general use of wireless
ltelegraphy. But with the advent of
the much simpler radio telephony. in
the last two years. traffic has be-
come so congested that the present
laws will have to be changed so as
to conform with the rapid progress
of this science.
Rules for Sending
Until the new laws are passed. the
following rules will govern the
transmission of messages by radio
phone:
Every person desiring to transmit
messages must obtain a license from
the radio inspector of the district in
which the station is to be operated.
lControI of radio is in the lands of
the bureau of navigation of the De-
partment Of Commerce. No charge
is made for a license.
Radio transmission is divided into
three classes, for the purposes of
Limitation and control. Government,
Commercial and amateur.
Government radio transmission Is
unlimited in the use of wave length.
| The federal stations, however, have
, aar6naH THAR mQGga RpG 10 WAVE
lengths above those allotted to com
mercial and amateur stations.
Commercial stations are allowed
special wave lengths to transmit
their messages, and a certain time
at night for their exclusive use. Et-
forts are being made now by the
government to allow the commercial
companies greater leeway in the
transmission of their messages.
Trouble With Fans
Greatest difficulty is found in con
TROLLING the vast army of amateurs.
At present the law divides amateur
stations into three groups:
1. The limited commercial class
of stations, which under special IL
cense are permitted certain wave
Lengths, most of which are between
$50 and SIS meters. All broadcast
ing stations are in this group.
2. The large run of amateur sta
tions are permitted a power input OF
one kilowatt and are limited TO a
wave length of 200 meters.
3. Amateur stations within v
ngutical miles of naval radio stations
are limited to one-half a kilowatt IN
put and wave lengths up TO zoo
meters.
There are also experimental sta
IT, T. A. sgNts alaSa and school
and university stations in the "Y'
~lclass, which have special permission
from the secretary of commerce for
the use of longer wave lengths ana
higher power.
The following program VIII be
broadcasted tonight and tomorrow
