With the many circuit diagrams
- available today, some of which are
very efficient and some of which are
not, the layman gets confused when
he starts out to get a circuit which is
simple and still workable. The un-
initiated may tackle the neutrodyne
| (along with old-timers) with assur-
‘ance of success. When this set is
‘built on low-loss lines it is a charm.
i It is simple to neutralize and easy to
operate. The neutrodyne has received
some “booing,” but this came from the
| people who didn’t take the pains to
| build the set propertly, and also those
: C : who used poor and inefficient material.

a poorly insulated antenna, when dur-
ing the damp weather the insulators
get wet and start to leak, thereby
broadening the tuning and unstabiliz-
ing the set also.
| All the neutroformers are wound
seriatum on one low-loss form for the
basket-weave type. The panel of the
set is the same as that of the stand-
ard Neutrodyne, that is, it has the
conventional three dials, one rheostat,
‘a filament switch and the two jacks.
. You, therefore, can purchase a drilled
panel that was originally designed for
the Neutrodyne and use it for this set
withcut going to the trouble of drill-
ing the holes and also making the en-

down from the remote past. They live Thiet wiles sielehiling me
because of their inherent truth. One of quency condensers are used for tun-
ing. The five sockets should be of the
porcelain base type. The neutralizing
condensers are variable from .000015
. to .000019 mfd., and are very easy to
adjust. The resistance across the grid
and filament of the detector tube is a
variable grid leak. The grid condens-
er is a .00025 mfd. (mica). Jlis a
double-circuit jack, and J2 a single- :
circuit jack. Five UV201A tubes are |
used. Make sure that when you pur- |
chase the tubes that the prongs do not
shake and also test the tube in a set:
and see if it is noisy, as this is the |
cause of a lot of trouble in neutro- |
Changing around of tubes will help .
a great deal in making the set work
efficiently. A filament switch, a ter-
minal strip, a 6-volt storage battery,
two 45-volt B batteries and a 43-volt
C battery are needed. The resistances
A are amperites, type 1-A.
If you desire to drill the panel, the
following data are given: Six and a
half inches from the left of the panel
and 33% inches from the top of the pan-
el driil a hole for the first dial, which
is a 4-inch dial; 6% inches from this
hole and 3% inches from the top of the
panel drill the hole for the final dial. |
All the holes are 3-16-inch in diame-
ter. Six and a half inches from the
left of the panel and § inch from the
bottom drill a hole for the first jack,
J1, the diameter of the hole being 2-
inch. In the same line and 13 inches.
from this hole drill a hole for J2, also
3-inch in diameter. Three inches from~
the right of panel and 2 inches from
the bottom driil a hole for the rheo-
stat, the diameter of the hole depend-
ing on the type of rheostat being em-
ployed. Going back to the left-hand
side of the panel, 3% inches from the
left and 1% inches from the bottom
drill the last hole for the switch, the
diameter of the hole being % inch.
HOW TO WIND THE COILS.
The coils are wound in basket-
weaver fashion. L1L2, if desired, may
be made in a continuous winding. Us-
ing No. 22 DCC and a 3-inch diameter
form, with 15 dowel sticks equi-dis-
tant on the circumference, wind ten
turns for L1 and 50 turns for L2. The
division of the two windings is denot- |
ed by a tap. Both the ground and the
A minus are connected to this tap.
This affords conductive coupling of the
aerial to the grid. For conductive
coupling L1 is wound separately and
so is L2. The two other transform-
ers, L3L4 and L5L6 are wound with
ten turns of the same kind of wire for
- the primary, and 50 turns secondary,
‘tapped at the fifteenth turn for the
connection of the neutralizing con-
The single winding on the aerial coil
works very well, but a little more se-
lectivity will be obtained by following |
the diagram, with the two windings
The coils are wound “under two and
over two.” When the winding is fin-
ished the coil may be raised about 1
inch from the form and cord inserted
in a wave form through the inside
length of the winding and knotted for
security, or the cord may be employed
in any other fashion for support.
The cotls are removed from the
form after this lacing is completed.
L1L2 is mounted on the baseboard at
least 2 inches in back of C1, the coils’ |
“axes parallel to the baseboard (wind-
ings at right angles to baseboard).
| For this purpose two dowel sticks may
be used reinserted at tw adjacent
holes in the winding, using two 2-
inch hard rubber or brass right an-
gles, secured to the baseboard and to |
the dowel sticks. L5L6 is mounted in .
the same way. L3L4 is mounted with |
its axis perpendicular to the base-
board, the more conventi®nal fashion.
Thus adjoining coils are at right an-
‘gles to each other and magnetic inter-
‘ play is successfully avoided.
| Place all the instruments in their
respective places, taking care that the .
RFT are all near their own sockets, |
so as to have very short leads, and
thereby save some energy. |
THE WIRING OF THE SET.
Bring the beginning of the wire of .
L1 to the antenna post of the termin-'
al strip and the end of the coil (this
being the ten-turn primary) to the
ground. Connect the beginning of the
secondary coil L2 to the stationarv
plates of the condenser, C1, to the grid
i post of the socket, and to one end of
| the neutralizing condenser, C2, the
end of C2 going to the fifteenth-turn
tap on the ceil, L4. The beginning of
the coil, L3, goes to the plate post of
the first tube socket, the end of this
coil going to B plus post, 67% volts, on
the strip. The end of L2 goes to the
these is :

Thoughtful men realizing this do not put off

come at any moment, and they prepare for it by
arranging for a proper distribution of their estate.

side of the audio amperites.
HOW TO NEUTRALIZE THE SET.
Neutralization is a simple process
of follow out, but it takes a little time
to get it just right. Put a small piece
of paper between one of the filaments
of the second tube from left and the
spring on the socket. Push the fila-
ment switch out and light the tubes,
then tune in a loud local station. If
you hear the least undertone of a sig-
nal, there is some interstage coupling
present. Adjust the small neutraliz-
ing condenser until this signal disap-
pears. The same procedure is follow-
ed out with the first tube (extreme
left). Both settings are left perma-
nently and should never have to be
touched, except if the ground is
changed, which may change the ap-
parent capacity of the tubes through
the interchanging of current from the
coils, and which in turn will change |
the capacity effect of the neutralizing
condensers.—By Neal Fitzalan, in Ra-
Oyster Season is Here.
The oyster season, lasting during
the months containing R, is at hand.
Purveyors of bivalves have been noti-
fied that the oyster boats are out and
shipments can be expected shortly.
June to August are the spawning sea-
son of the oysters, when they are not
disturbed. Cool weather also seems
to add to the flavor.
Oysters are one of the cheapest ar-
ticles of diet at the present time in
the United States, considering quality.
Baltimore is the great oyster city of
the world. The best oyster beds are
located in the Chesepeake bay, along
the coast of New Jersey and Long
Most oysters after being dredged
out are put in fresher water for
plumping, losing some of its salty
taste and giving it a fatter appear-
ance. Oysters, it is stated, are ready
for the table in a year and a half and
are at their best at three years of age.
Better Roads Cut Cost.
American motorists cash in a year-
ly dividend of 10 per cent. on the cap-
ital invested in the improved high-
ways of the country. It has been es-
timated that the average car runs 6,-
000 miles a year. A saving of 2%
cents a mile for 6,000 miles amounts
to $150 a year. For 17,000,000 auto-
mobiles this means a saving of $2.-
500,000,000 a year on gasoline, tires,
parts, upkeep, renewals and all phas-
es of operation.
It is said of the clever Magyar of
Hungary that he never goes to bed,
but gets up at seven o'clock every
morning, that he never has any money
and spends it royally, that he never
puts off until tomorrow anything he
hopes he can induce somebody else to
do for him next week, and that he
never works on Sunday or any other
day if he can help it.
