Overhauling of
Radio Sets for
Winter Advised
Outfits I -ose Efficiency Dur
ing Summer Storage,
Claim Ex
perts.
Hy FREDERIC BORTZM EVER.
With the arrival of fall the radio
season proper reopens for the winter.
Those of us who put away the set
entirely for the summer will now
soon he reinstalling it, and those of
us who built a portable receiver for
the past months will be storing it
away and turning to our old winter
standby.
At all events many radio fans will
be resuming their pastime of listening
in. Some will have their expectations
as regards the performance of their
old set entirely justified, but how
many will he disappointed and puzzled
at their set's failure to function with
all its old vim and punch? It may
seem ahsurd that a set will lose its
efficiency in a few months of dishse,
hut that such Is the case oftentimes
has been proved in the past. This
article is written in the hope that
much trouble and expense on the
part of the radio fan and the Junking
of a good set which needs only over
hauling and cleaning may be done
away with.
Ordinary Dusting Not Enough.
It Is not sufficient to wipe all the
visible dust from the interior of the
set. Every instrument composing it
should he thoroughly cleaned. Several
small, soft, clean cotton cloths and a
piece of stiff wire will be sufficient
lor dusting the set.
Do not overlook the inductance
coils, for dust lodged between turns
of wire will assist in making the set
a broad tuner, and, because of the
greater distributed capacity, will also
cause reduced signal strength. Dust
furnishes shorts and by-passes for
radio frequency currents.
All wiring should he gone over in
case some unknown accident may
have happened to the set while it
was in disuse. It may have been
subjected to some mechanical shock
about which you know nothing, and
it the wiring has been Injured you
may burn out a tube or two as a
consequence of a short circuit. If
the set has been stored in too warm
a place any surplus soldering paste
which map have been left under a
terminal or a lug will have melted
mid possibly caused corrosion. Again,
you may have been In somewhat of a
hurry to try out your new portable
when you stored the old set last
spring ami may have accidentally in
jured some of the wiring.
As mentioned before, all of the In
dividual instruments composing the
set should he inspected. Dust col
. lected on the plates of variable con
densers greatly alters their capaci
tance values and consequently their
efficiency in the circuit for which
they were intended. Pigtail connec
tions to moving parts may need to
lie resoldered to the shafts before
they are capable of being put to hard
service all winter. Contact springs
of tube sockets should he removed
from the sockets and filed until they
present a shining surface. This In
sures against a high resistance layer
of corroded metal being present be
tween the prong of the tube and the
metal proper of the contact spring.
Good contact at this point is espe
dally important in the grid circuit.
Renovating Jacks.
Telephone jacks should have the
assembly screws tightened, because
0 temperature changes and tension and
stress of wiring may have forced
them loose. Good contact between 1
the spring arms may he had I " j
drawing a piece of very fine sand
paper through the arms. The pap< i
should be drawn through twice only,
once with the abrasive side toward
one arm, and once with It toward the
other. Do not draw the paper
through repeatedly. The contact ,
points on the spring arms are usual-1
ly of silver, a comparatively soft j
metal, and these must not he worn
flat.
If your set has the panel com
pletely shielded, each instrument
should he individually tested for
shorts to the shield and ground. If
It has not heretofore been shielded
and you wish to provide against
body capacity, the following steps
must be taken:
Remove all instruments from the
I lack of (he panel, and with shellac
apply a sheet of metal foil over
the entire panel. From the front of
the panel puncture the shielding
through the shaft holes and mounting
holes. Turning to the back of the
panel again, scrape away the foil
from each of the holes, leaving a
spare about the size of a dime un
shielded around each hole, as shown
in Fig. 2. Now the Instruments
may be remounted, all being held
clear from the shield by fiber wash
ers over the shafts and mounting
screws, as Illustrated by tbe side view
in Fig. 3. With the shield grounded,
the set will be free from many ex
traneous noises and from body cap
acity.
Some vacuum tubes refuse to oscil
late when new or after a long period of
Inactivity. This trouble sometimes
can lie remedied by placing the tube
In the circuit and allowing it to re
main lighted for some time. Although
• B" batteries have great recupera
tive strength, they will not perform
efficiently after a long period "on
the shelf." It must he remembered
i hat the plate circuit voltage must he
kept above a certnln potential, be
low which the tube will not function
at all. Thus your battery may not
lie dead, but may produce a potential
below the operating point of your
tube.
Compression type rheostats should
lie taken down and cleaned and all
metallic contact points inside the In
strument polished with emery cloth.
Several of these points are shown In
Fig. 4.
in front of the panel we will not
find much to offer serious trouble.
The apace between switch points
should be kept clear of dust and
grease. Panel mounted grid leaks
should be readjusted and firmly
fastened to the panel. Wraped dials
will not provide a reason for a set's
failure to function, but thev are very
annoying and cause dial readings lo
he Inaccurate.
i*tf you have not used your an
Memory Test Given
on Radio by Omahan
The possibilities of the memory
were demonstrated lost night by AV.
R. Buckner over WOAAV radio, lie
has a national reputation for his re
markable memory.
He was blindfolded under super
vision of Mayor Uahlman. Then
numbers from 1 to 30 were placed
on a sheet of paper and opposite
each number was placed a word or
letter. Radio listeners were asked to
do the same, Mr. Buckner merely
listening while tlie words or letters
were written.
Then, speaking Into tlie microphone,
Mr. Buckner called off the words
without error both forward and back
ward and with great rapidity.
"Visualizing with the miml is the
secret of a good memory," he said
afterward. “Association of Ideas and
word pictures causes the machinery
of memory to work.
“Upon meeting a person be sure
and hear his name correctly. If you
do not hear it ask that the name be
repeated. People feel no discourtesy
in this, but, on the contrary, they
like to think you are interested
enough in them to try to remember
their name. After hearing the name
correctly try to get some thought in
connection with the name which will
tend to impress it more permanently
upon your mind. Perhaps you know
someone by the same name, or take
the meaning of the name. A large
percentage of the names which you
hear have a very definite meaning.”
all summer and have allowed it to
hang grounded, it would be a safe
plan to follow to lower the aerial
and inspect the insulators, joints and
guys. If the wire he badly corroded,
it would be best to replace it with
new.
Overhauling the Antenna.
Cracked insulators should likewise
be replaced. All the into ? Insula
tors should be washed 'ban of dust
and smoke particles. » ut the aerial
wire from the insulator st before
the point at which it is connected to
the latter and then re.-i»nn»- t. it at
the new end formed, as shown in
Figure 5. This provides against the
aerial wire breaking this point
because of the soften i condition of
the wire, caused by its being bent |
backward and forward so frequently.
Inspect the soldered joints and s^e
if the guys hold the aerial station
ary. Turnbuckles (Figure (i) placed
in the guys assist in keeping tlie
aerial under proper and constant
tension.
From the foregoing it is easy to
see the great ffumber of places in
which trouble may be found and
remedied in a set which has been
“carefully’' stored for the summer.
An automobile which has been in
storage for some time must be thor
oughly overhauled and retuned be
fore it will operate with its old ef
ficiency. If this 1»e the case, how
much more carefully must we pre
pare a radio set, in which the initial
electrical energy furnished us with
which to work is so small! In stor
ing your set next spring think of a
few of the difficulties with which
[ you met this fall and guard against
their recurrence.

AIR-DRIVEN SHIPS

1 London, Nov. S—The propulsion of
a boat by air beneath the waterline,
recently demonstrated in London, will
revolutionize marine engineering, it
Is believed.
The invention of an Australian en
gineer. the device does away with
propeller sftnfting and thrust block,
thus saving frictional losses in speed.
An engine-driver blower in the
forepart of the boat forces air ;
through tubfn, running under the
bottom of the boat on each side of

thousands of hobs in the tubing in
