engineering genius at their COM
mand to simplify the reception of
distant short-wave stations.
Their progress. as exemplified by
the sets on display during the CITY,
wide radio progress exposition, has
been sufficient to enable a child of
average intelligence to bring in for
eign broadcaStS.
But to get the most out OF the
low bands which can reach almost
around the world, there are some
important things arising out of the
very nature of Short-Wave broad
casting which you should know and
observe.
Though the development of short
wave transmission has been ad-
vanced rapidly, it is still not per-
feet and not all of the foreign sta
tionS have sufficient power to carry
their broadcasts everywhere with
signals of equal strength.
Wave Lengths Change
Neither does every short-wave
station broadcast at all hours of
the day and night.
This means, of course, that you
can not expect to get Berlin, for ex-
ample, when Berlin is not on the
air. On the other hand, Berlin may
be broadcasting while you are away
from your radio.
Foreign stations sometimes, by
way of experiment, change the fire.

length), which means that you will
not find the same station always on
the same spot on your dial.
1t may vary bit.
The fact that a station is listed
for one frequency, does not mean
that it will not use others. Many
have several wave lengths. They
may pick any one of the several for
experimental purposes.
Most any time of the day or night,
however, weather conditions being
equal, there is a ShOrt-wave station
transmitting from somewhere.
Check Up Schedules
1t is a good practice to check up
on printed schedules which are
available through most any of the
radio stores participating in the ra-
dio progress exposition, for time and
wave length of the stations you
want to get by keeping your own
wave log.
Refer to your comparative time
tables for the time of the Sched-
uled broadcast, for you must re-
member that when it is day time
in America it is night over Europe.
Generally speaking, from daylight
to about the middle of the after
noon and particularly during the
brightest part of the day, you will
be able to get Shortwave stations

The twenty to thirty -fve-meter
spread has been found best for the
listener to the east, regardless of
whether the listener is in the United
States or in China, from about noon
to two hours before midnight.
After dark stations broadcaSting
on wave lengths above thirty-five
meters usually can be heard much
better than during daylight.
Be Patient
The twenty to thirty-f1ve-meter
spread will be found best for the
listeners to the west from about
midnight to daylight.
Above all be patient.
Tune slowly.
Go back and forth over each band
carefully. Then you will get the
best results.
Radio makers have taken the hu-
man element of Impotence into con-
Sideration, apparently, in the con-
Struction of the new allwave sets,
for they have provided them with
dual-Speed tuning knobs and band
spreading devices which in sense
magnify the dial over which your
needle passes.
This makes careful tuning easier.
