the supervision of a radio inspector
whose business it is to see that they
confine their operations to short dis
tances only. Nevertheless. when the
great trans Atlantic tests were made
by American, English and Scotch am
ateurs on the memorable night of
December z, 1921, the code signals of
26 different Americans. most of them
using home made equipment were
distinctly heard in Scotland.
The acquisition OF the usual anna
teur radio receiving station is a very
simple matter. You can have one
installed in your home for the sum
of $50 up to $3.50, depending upon
the nature of the equipment. OF
course. there is always the possibil
ity OF unreasonable opposition from
your landlord, who is apt TO look
upon the aerial antennae as an eye
sore and as a fire menace, but this
difficulty is likely 10 be eliminated
as the landlords themselves become
converts to the radio sport. AL
though the equipment may have its
drawbacks as a roof ornament. there
is positively no danger from fire.
say the experts. IL the wires are
properly installed.
Sending sets are not quite so easy
to acquire and operate. The opera
tor must be able to read a certain
number OF words of the Internation-
al communication, code. so that he
may understand any pre-emptory
command to get off the air. from
the big coastal wireles stations. This
command will be heard whenever
at sea. In such an event it is up
TO the amateur operator to quit
transmitting. but he need not refrain
from listening to the messages as
the work of rescue gets under way.
Amateur Senders Limited
"At present" says a radio expert
mo amateur may send on more than
a 200 meter wave length, nor is he
permitted to develop more than one
kilowatt of power. He is the lowest
in the scale and IL anywhere in the
neighborhood he can no more inter
rupt the $50 meter wave length
broadcasting concert or the 1000 to
$4,000 meter wave length trans-At-

a MOSQUITO can drown out the roar
Of a subway express train"
Although still in its infancy. the
radio telephone is already playing an
important as well as somewhat spec
tacular part in our everyday life.
1t is the agent by which the bureau
OF markets of the department of agri-
culture daily broadcasts its crop,
weather and market news through
out the country 1t is the narrator
of bedtime stories to thousands of
sleepy children The United States
public health service uses it TO broad
cast two lectures on health every
week. 1t is providing a large and
eager audience for Sunday sermons
such as has never been enjoyed by
ministers of the gospel before. 1t has
been known to lull a baby TO sleep
with its music and TO carry the sound
OF jazz so clearly to a vessel at sea
that the passengers were able 10
dance. Most newspapers now give
the nightly radio programs a con-
spicuous place in their columns. and
one large New York daily devotes
an entire page in its Sunday issue
to radio news There are nine mag
azines devoted to radio and a long
list of books.
Yet the rise in radio has Just be-
gun. Think of what it will be doing
10 years from now when all OBJ
stacles will been removed. and il will
be as easy TO talk to Paris as it is
to phone downtown. The common
telephone. by connecting us only too
efficiently with the world, has al
ready destroyed the comfortable pri
vacy our grandparents knew. but
fancy what our grandchildren will
have to endure when they will be
compelled TO hear so may unpleas-
