NEW YORK, May 3O.-The ex-
tent to which this will be a radio
summer is becoming apparent with
the ever-increasing efforts made by
broadcasters, manufacturers and
other interests in the radio industry,
to set high.water mark of|perfec-
ton for radio reception during the
coming months.
Requests from many parts Of the
United States have led the Associ-
ated Manufacturers of Electrical
Supplies, which includes in its mem.
bership all the leading elements in
the radio industry. to issue some
suggestions to the radio public.
Little difficulty should bo ex,
perienced in securing good recep.
ton in the summer, 1t IL pointed
out. as during the past year thd
power Of sending stations has been
materially increased. This 10 ex
pected to- eliminate many Of the ,
previous difficulties noted durinS
the summer months.
The suggestions follow:
! Put your set in the pink a
| condition. See that the Connections
/ are gone over and frightened IN.
that old batteries are replaced, and
that good set Of tubes are in
stalled.
Radio in Camp.
Pin camping with a radio ~.
your receiver Is one Of the antenna
type, erect your aerial wire from
the camp to branch Of one Of thE
taliest trees in the immediate
vicinity. II thunderstorms are
prevalent 1t will be found advlsableA
TO erect an additional antennA moi
over ten to twenty feet off the
ground. That type Of aerial Il nc.
go readily influenced by atmo
phertc disturbances. An aerial
this character can be Of anv ienet
from 100 to 200 feet.
3. Whether you use q receive
which operates from q loon. or
receiver which operates from
antenna, the sensitiveness OF Il
receiver should be reduced in tim,
OF atmospheric disturbances eth.
by reducing the filament temnAf.,
ture or by ''loosening the couplinR y.
SO that the best results might Il.
oDtained from your local station
On the other hand, II atmoSphNr
conditions are good, the flame,
! temperature should be readjusted
normal, so that the sensitiveness
the receiver might be increased ar
reception obtained from broadcast,
stations located at greater distance
The long, low aerial, or the loo
type OF receiver, will give nnarke
| relief this summer from atmosuhari
disturbances.
Good Ground Essential.
4..Sae. that you have a roof
ground connection when the aeriai
iS used. II such\ cannot be obtained
at the camp or at the seashore.
the equivalent Of good ground
connection can be had in the use
Of a piece Of wire, 100 to 200 feet
In length, laid over the surface OF
the ground and directly underneath
the aerial.
s. Receiving apparatus In the
camp should be duly protected from
moisture and dampness. A mod.
crate amount of moisture and
dampness may not interfere with
the operation Of the average type
Of receiving set but at least the
set should not, be allowed to ret
Ewet by exposure to rain or lmcle-
ment weather.
6. Broadcast listeners should bear
in mind that the electrical constant
Of aerials erected at the seashore
or in a camp may be quite different
from the electrical constant Of the
aerial used with the same set at
home. This means that stations
formerly heard at home win not
come in at the same point on the
dials in the camp. It should not be
difficult to locate new positions for
such sets.
Z. With regard to head tele.
phones, bH sure that the headset
cord is not worn; that the connec-
tons are tight at the back Of the
headphone and that the caps also
are screwed down tight.
