Loop Aerial Is
Now Popular
Small and Compact, Sharp
in Tuning; Easy to
Disconnect.
The use of the loop type of aerial
Is gaining In popularity among radio
fans. It Is small, compact, directional,
and is sharp in tuning, making It
effective In places where there Is
much Interference.
To get the utmost efficiency with
this type of aerial It must be pointed
In the direction of the station which
you wi*h to listen to. For this rea
son loop aerials are generally fitted
with a swivel base to allow for free
turning In any direction.
A convenient method of accom
plishing this Is to fit the end of the
vertical loop support stick into an
o^inary telephone plug, connecting
0ri4Re two ends of the winding to the
two terminals of the plug. This fits
into the jack and allows the loop to
be rotated, yet still make contact
with the receiver connections which
are fastened to the jack prongs.
I.
The o'rdinary type of jack, designed
to be ueed on panels with a thick
ness up to one-quarter inch, is diffi
cult to use through the lid of the
cabinet, which Is generally a half
inch thick.
A type of Jack and plug, designed
by MaJ. Herbert H. Frost, Is made
especially for use with a loop and
has a number of advantages over the
ordinary type of plug and J-'ek for
tble purpose. It can be used on the
lid of the cabinet by simply drilling
a single hole. A large nickel plated
face plate fastens to the top of the
lid covering up any damage that has
been done In drilling through the
aggMffed and braces the jack so that it
is perfectly rigid, even when holding
a heavy loop.
Springs Far Apart.
The springs on the jack are far
apart so as to keep the capacity as
low as possible. The terminals are
fitted with screw connectors in place
of soldering tips, so that flexible wire
leads can easily be attached and
disconnected.
The plug is extra large and long,
and the bottom end of the loop frame
can be easily inserted and firmly held.
The two terminals at the side are
for connecting the two ends of the
winding. The terminals go through
the cover of the plug, making a low
resistance connection.
The use of a loop plug and jack
combination Is very good where the
loop must be removable. To discon
nect, you Just pull out the plug. The
Jack allows the loop to be rotated In
any direction without breaking con
tact or twisting up the connections.

Builders of Radio Sets Should Have Hoyt's Wave Meter; Construction Is Easy
By HIRSCH M. KAPLAN.
Francis R. Hoyt, inventor and
engineer of considerable note, whose
testing equipment has been the sub
ject of several articles appearing in
this newspaper, recently remarked
that “the two most valuable instru
ments in the laboratory of the radio
experimenter are, without question,
the oscillator and the wave meter. Of
these, the wave meter is the more im
portant.”
This week the wave meter em
ployed by Mr. Hoyt for general
utility purposes is being described in
detail. The constructional features of
cuit Is shown In either of the two
schematic diagrams accompanying
the actual wiring diagram of the
completed wave meter.
This combination of coil and con
denser constitutes what is known as
an oscillatfng circuit. By varying
capacity of the condenser in this
oscillating circuit, the natural fre
quency of oscillation can be made to
correspond to the frequency of an
other oscillating circuit.
When the wave meter is used as
an Instrument for the comparison of
frequencies, some sensitive indicat
ing device is connected in series or
three cord tip Jacks (these are shown
both in the photograph and in the
wiring diagram), which permit the
headphones and crystal to be un
ilaterally connected or bilaterally con
nected at will. The use of cord tip
Jacks avoids the capacity effect of
the conventional Jack which is of the
order of from 10 to 12 micro-micro
farads.
The double pole double throw switch
permits a quick change from the
standard condenser of the wave me
ter to an unknown condenser under
test. This unknown condenser should
be connected with very short connect
the colls do vary to a small degree,
yet they are more uniform thaln Is
general!^ believed: but since the ex
act Inductance will have to be used
for measurement purposes, they pro
vide an excellent starting point.
When the exact lnductaijce of the
coll to be used for a given wave
length range is determined, this in
ductance should he marked in Ink on
the Inside of the coil, and It should
be laid aside for use in the wave me
ter only.
The following table gives the gen
eral characteristics of coils of this
type:
under test as its operation will per
mit; this will prevent any possible
reaction of the wave meter on the
circuit under test. To couple the wave
meter to the set under test, the duo
lateral inductance which is mounted
at the extreme rear of the baseboard
(shown in the photograph) should be
placed in inductive relation to the
coils of the receiver or transmitter.
The variable condenser of a wave me
ter is then rotated until a maximum
response is registered in the phones.
At the point of maximum response
the wave meter is in resonance with
the waves to be measured and the
^ testing panels. to right they a for measuring voltage
panel, a biasing battery panel and the wavemeter.
this wave meter are of particular
value to the experimenter, art all of
the parts can be obtained on •’
open market, thus eliminating home
construction of the necessary accur
ate but tricky inductance coils.
A definition of the term wave
meter might be summed up about as
follows: A combination of apparatus
by means of which the length of
electromagnetic waves generated by
so'me outside source may be meas
i — —
In shunt In the rlrruit, to register the
current in the coll or the voltage
across the condenser. In the ordi
nary applications of the wav* meter
this sensitive device takes the form
of a pair of telephone receivers and
a detector, a hot wire ammeter, a
Neon tube, or a galvanometer and a
thermo-couple. When the wave meter
is used as a generator of waves, the
Indicating device is ordinarily re
placed by a buzzer and battery, which
ing leads to the binding posts on the
left in the photograph (shown also on
the diagram.)
The condenser used In the wpve
meter is the General Radio .001 mfd.
variable, geared vernier type (a plain
dial, is shown In the photograph)
which comes supplied with a dfal
graduated both in degrees and In ca
pacity values in micromlcrofarads.

and the length of the wave will be
indicated by the dial reading.
The two methods of connecting the
headphone*, unilaterally and bilater

accurate measurements can be made.

of a desired length when excited by
some outside source. It is therefore
a calibration instrument which may
be used to measure the length of
electro-magnetic waves, the In
ductance of a coll, the capacity of a
condenser, or the decrement of
electro-magnetic waves.

meters is the same, and one general
circuit diagram will cover any wave

Const ruction of Wave Meter.
Four of Mr. Hoyt’s testing panole
are shown in the illustration this
week. In their order from left to
right they arc: an Instrument for
measuring the voltage amplification
of radio frequency amplifiers, a bias
Ing battery panel, n pickup and
transfer panel and on the extreme
right the wave meter.
The complete wiring diagram for
the wave meter Is furnished, and the
two schematic diagrams show the
method of connecting the headphones
and crystal detector for either
unilateral or bilateisl connection.
The wsve meter la so constructed
that an unknown coYidenser or an
unknown Inductance may ha substi
tuted for the known condenser or
known Inductance, thus permitting
arcurate measurements of inductance
and capacitance.
The wavs meter is equipped with
recommends that the ejyjerlmenter
use the (leneral Radio dial supplied
with this condenser. The direct read
ing capacity values are of great ns
slstance for coll and condenser meas
urements.
Duolateral ’ colls are used for the
Inductances, and bjr substituting
smaller or larger coll* the wave
length range can he made to conform
to any desired minimum and max!
mum. The duolateral coll Is particu
larly suited for wave meter work In a
utility wave meter. In this type of
coll the distributed capacity for a
given Inductance Is lower thnn In any
other type of winding. The physical
dimensions of the coll are admirable
for an Instrument of this kind, It Is
an easy coll to coupls to an extrane
ous oscillating circuit and does not
easily change Its Inductance with or
dinary usage.
Duolateral colls come In various
sixes end sl| rolls of one size are sup
posed to he of the earna Inductance.
While this Is not exactly the case,

DU 1.500 175 00* 5.200 25.900
It will b# seen from the shove that
t hecoll-condenser combination as em
ployed In this wave meter will give a
wave length range from 130 meters
to 25,000 meters. The colls have been
shown In the table In the values or
steps In which they are manfunctur
ed. These stages Or steps provide a
considerable overlap and tt la obvi
ous that all of the colls are not re
quired to cover a given range. For
Instance, the DL 25 and 50 will tune
from 130 meter* to “30 meter*.
3Vhen It Is desired to measure the
wave length of a received or trans
mitted wave, the wave meter should
be as loosely coupled to the circuit
the crystal and headphones sre not In
the osrllatlng circuit, and the reso
nance curve of the wave meter Is
therefore very much sharper. It Is
often desirable to use the bilateral
arrangement to get the Initial adjust
ment* and then change t* the unilat
eral connection for final readings.
Ground Load* Short.
]f possible, the ground lend should
he kept up within a length of four to
five feet. Lohg ground leads not only
broaden the tuning of a set, but also
add a resistance to the antenna
tuning Inductance. Wherever possible
the receiver ehould be. located as near
the ground connection as space will
permit.

World Entering New Radio Era;
15,000,000 Sets Now in Operation
Washington, Feb, 13.—The world ha*
entered Into the radio era, according
to Dr. J. H. Dellinger, chief of the
radio laboratory of the United States
bureau of standards.
Exhaustive studies of wireless com
munication have been inaugurated by
the government, looking to the im
provenjent of broadcasting and recep
tion by the public. The "circulation"
of the broadcasting stations of the na
tion run* into the millions—it is esti
mated that there are more than 15.
000,000 receiving sets in operation.
"Aaurvey of progress in radio re
veals that this la the era of radio
engineering," Dr. Dellinger said. "This
statement does not refer to the Im
portance or extent of radio engineer
ing, but to the type of development
now going on ih radio, as compared
with that of past years.
"Relatively speaking, radio has been
crude heretofore, whereas the progress
now being made is not merely em
pirical, but Is more largely character
lied by actual engineering develop
ment. We have not so much the
invention of devices now as the per
fection of them. Engineering of radio
has taken definite form, and is the
tool by which further progress will be
wrought."
Included in the noteworthy devel
opments of radio by which Dr. Del
linger mentioned were marked exten
sion of the available frequency range,
great improvement in directive radio
transmission, advances in the perfec
tion of selective radio systems and en
gineering development of line-radio,
or carrier current communication.
"Among radio devices and ap
pliances," Dr. Dellinger continued,
“there Is outstanding progres on
radio beacons, on the use of radio
for aircraft navigation, on direction
finders and on radio vision. In the
field of research and study we have
Important progress in radio measure
ments, in standardization of appa
ratus, In the study and mitigation of
the vagaries of wave propagation and
atmospheric disturbances and in the
wide reaches of the interference prob
lem.”
Among conspicuous achievements
was mentioned that of the "conquest
of the new domain of ultra-radio, or
very high frequencies, the short wave
lengths." Even the existence of the
vast range of frequencies below 150
meters, according to Dr. Dellinger,
hardly was suspected and "certainly
was generally forgotten up until less
than a year ago."
"One curious reason for the subor
dination of this range of frequencies
has been the erroneous use of wave
length in meters as an expression of
radio frequencies," he explained.
“Radio engineering actually deals
with currents which have a certain
frequency. The length of Vile wave
a* it travels 'along in space can be
calculated from the frequency, but it
is a derived and artificial concept.”
Dellinger said that frequencies up
to 20,000 kilocycles have come into
extensive use. Actual radio service*
sra being conducted in this region by
broadcasters, transoceanic communi
cation companies, military services
and amateurs. Even higher frequen
cies have been used in experiments;
"but," he added, "there is every like
lihood that in the development of fre
quencies above 20,000 kilocycles d!
rectlve transmission will predominate
and the problems will be of a dis
tinctly different character.
"So important are these high fre
quencies that the third radio confer
ence parceled out the high frequency
territory among the various services,
thus reaching a solution of a problem
which only a year ago was regarded
as Insoluble, that of finding more com
munication channel*,'' the authority
asserted.
"Alternate frequency bonds, ap
proximnteiy 10 per cent wide, were
■- ■ ■- ■■ n-- — ■■ — " — "
assigned to the following different
services: Land point-to-point, aircraft,
ship, relay broadcasting, public serv
ice, amateurs and mobile army. An
Important principle was followed In
this assignment—that is, each aervice
was protected from possible harmonic
interference from stations of the other
services by placing the several fre
quency bands of any given service of
its own harmonics."
Improvement in directive or beam
transmission has been accomplished
by using a number of transmitting
antennas and so adjusting the phases
of the current in each, in relation
to their distances apart, that rein
forcement of radiation is obtained
in one direction and more or less
neutralization of radiation in other
directions.
"An obvious advantage of beam
transmission," Dr. Dellinger said, "is
that much lower power is required
than in ordinary radio transmission,
since the transmitting power is all
utilized in sending the waves in the
desired direction instead of in all di
rections."
According to Dellinger, one of the
principle means of overcoming inter
ference between the transmissions
from simultaneously operating radio
stations is Increase of selectivity or
narrowing of the band frequency
which each station uses.
“The various causes of interference
divide into two great classes—natural
and man made," Dellinger continued.
"Progress is being made eteadily
against both of these enemies. ,As to
the natural interference, there will
always be a certain residum of at
mospheric disturbances and fading
which will necessarily limit the dis
tance from any broadcasting station
at which reliable, satisfactory recep
tion will be possible.
"The various kinds of man-made
interference, on the other hand, are
curable and are of local character;
it can be expected that more and
more localities will be freed from the
various types of this pest.
"The battle against interference is
being won, in spite of the enormous
increase in the use of radio."
Importance of Location.
The signal strength of a radio set
will be affected if the cabinet is on a
table located near a steam radiator or
other metal, or if the aerial lead is
parallel to absorbing material. The
difference is remarkable sometimes
when the set is moved to another part
of the too mor house.
Poor battery connections cause con
siderable Interference.
A Remarkable Incident.
Samuel Hail of Matlock, England,
who has been deaf for 40 years,
found he could hear after listening in
on the radio.
