tered with this method, however, that
cause other effects in the coil that
either neutralize the good of the nom
parallel winding or in other ways de-
stroy the coil efficiency.
STAGGER STYLE BEST.
In order to obtain mechanical
strength honeycomb coils are wound so
that punching and piling of the wind
ing occurs at the edges, where the
"cross-over" occurs. Sometimes this
feature adds more self-capacity than
the style of winding subtracts.
The minimum self-capacity is OBJ
tanned by staggering or non-paraleling
the winding turns. At the same time
the inductance obtained from this form
OF coil is less unless a greater length
Of wire is used than in the case Of the
layer-wound coils.
In some forms Of low sclf-capacity
windings the length OF conductor be-
gins to seriously affect the coil eff
ciency. Any departure from the sole
mold shape or winding requires a great
err amount Of wire to obtain in the
same inductance.
II we do not stagger or non-paral-
lei the Windings, distributed or self
capacity of detrimental values Is en-
countered. We also find that If the
windings are spaced too much we tend
to make the inductance less efficient
for the amount Of wire used.

WAVE LENGTHS
WILL NOT Be
CHANGED
Department of Commerce
Denies Rumor That $50
Meters Allowed.

NEW YORK, Sept. 5.-New broad
casting stations will not be author
lied to operate on wave lengths of
$50 meters, as insistent rumors have
spread throughout the United States
and Canada. Such reports are erron-
eous.
The Department of Commerce,
through Acting Commissioner A. J.
fryer of the Bureau of Navigation,
in letter to Joseph R. Freed, presi-
dent of the Freed-Eisemann Radio
Corporation, gives this official denial
Of these rumors:
"In accordance with the recommen-
dations of the conference held in
Washington, October 6. 1924, the
wave length band reserved for broad
casting was from 200 to 545 meters,
since which time the department has
been assigning for broadcasting only
wave-lengths within this band.
mo consideration has been given
by the department for any change
in the bands referred to-
Mr.. Freed said that within the past
few weeks he had received many in
quiries from the public to the effect
that they had heard circulated reports
of stations to use 80 meters or less.
He therefore communicated with
Washington that these reports might
be set at rest.

SCIENTISTS STUDY
RADIO PHENOMENON

A peculiar phenomenon has been
observed by radio amateurs in the
Eastern sections of the United States
as a result Of attempts to communicate
by short wave radio with the MacMil-
Ian Arctic Expedition. With very
few exceptions all transmission east
of the Allegheny noun aims has been
carried on extremely short wave
lengths in the neighborhood of seven
teen meters. At the same time in the
Central West the 40-meter wave
length has proved most effective.
Scientists are at loss to explain this
peculiar condition. The one notable
exception has been the successful ex-
change Of messages between the Polar
Expedition and that of the Radio
Broadcast Everreadyy short wave ex-
pertinent station, 2GY, located at Gar
den City, l.. /. Using very low pow
er that station transmitted and re
ceiVed messages for over an hour on
the 40-meter wave length although
other stations Of greater power located
in the East at approximately the same
distance from the expeditions base are
compelled to use the seventeen meter
wave length to accomplish the same
feat.

augurated September /, by the Crosley
Radio Corporation, Cincinnati. This
contest will continue until March /,
1926, in order that owners may have
six months time to report results dur
ing the winter months.
Powell Crosley Jr. is offering $1,000
as the capital prize, while a monthly
prize valued at 500 will be given for
the report Of the best reception during
each month.
Anybody in the country may enter
the contest upon sending an applica-

STRAIGHT LINE
C0NDENSERS
SUCCESS
Switches, Studs and Dials
Supplanted by New
Invention.

Old Lady Necessity was never so
busy mothering Inventions as she has
been since the advent of broadcast
ing. The nightly music which surges
through the ether has sharpened the
native inventive genius of Americans
and completely changed engineering
practice in the design of receivers.
Gone are the multiplicity of switch
cs. studs and dials which used to
adorn the panel of a set and add TO
the completely of it's operation. Now,
two or three smooth working dials are
all that one sees. This change has
been wrought by the practice of using
condensers only for tuning the re-
ceivers TO the different stations.
There is no doubt that the change
was sound development but the in
creasing number of broadcasting sta
toms brought about a most peculiar
condition. 1t was found that the
shorter wave stations were all crowd
ed on the lower numbers of the tun-
ing dials. and in many cases, fans had
great difficulty in selecting between
them.
THE NEW WAY
The first effort TO solve this prob
lem came with the straight line wave
length" condensers. These had pecT-
liar shaped plates, and their operation
tended 10 space the stations out more

however, that the ideal situation
would not be reached until a con-
denser was designed which varied its

quency changes.
The primary object Of a straight
line frequency" condenser is TO cover
a definite ratio of frequency for use
in a circuit which has a definite
amount of capacity. The new instru-
ment has a frequency ratio of 8 to l
and will cover the frequency range be-
tween 500 and 1900 kilocycles. This
range corresponds TO the wave lengths
between 200 and GOO meters, in other
words, the brodcast band.

WIRELESS PROVES
A PUBLIC SERVANT

For what was probably the first
time in history, Cincinnati aided an
other city in holding a municipal cele-
bration when Mayor Lewis Shank of
indianapolis. Ind, and his party
spoke from station WLW, in the in
terest Of the city's industrial week.
Owing 10 the fact that there Is no
station in indianapolis in operation,
officials Of that city designated WLW
as the Official one to advertise its cele-
bration.
The station also assisted Indianapo-
lis citizens by broadcasting a special
musical program during its pageant
with over n thousand decorated floats
in line. In the radio division there
were floats with receiving sets ana
amplifiers upon them, which picked up
the music broadcast from the Cincin-
natl station and paraded to its martial
melodies. This is not the first time
WLW has broadcast music for a pa
rade. for. during similar pageant in

BACKGROUND INDUCTION
SEEN AS IMPROVEMENT
By FRANK REICHMANN

The past year has seen wild hys-
terra in the matter Of low loss con-
densers. At the present time we are
undergoing a similar condition with
respect to radio inductances.
Among the most common types are
the layer wound, pie wound, bank
wound, lateral and stagger wound and
space wound. All of these are Of the
general solenoid shape, or at least in
a form that may be classed as
solenoidal inductance, in which the
wires are wound in a circular form,
open at both ends. Each has its faults.
Each coil is designed to offer as
little resistance to the flow OF current
as possible and still retain the maxi
mum inductance, so as to transfer as
much energy as possible.
LAYER MOST COMMON.
The most commonly used type Of
coil is the layer wound inductance. 1t
is easily made and usually consists OF
q single layer of wire wound on an
insulating tube or form. This type OF
coil has a rather high distributed ca
pacity.
Distributed capacity is the name
given TO the condenser action that
takes place between adjacent wires in
n coil. When the wires are close To-
gether and insulated from one another
they act as small condensers, and when
the radio currents travel through this
condenser energy is lost.
When the distributed or self-capac'
ity of n coil is high. due to the fact
Il IL =
each other. the current travels across
the wires by this distributed capacity
effect and fails to serve completely the
function of the coil.
In the layer wound coils the amount
Of material and insulation used to sup
port the wires is large, making me
losses in the coil correspondingly large.
The self-capacity is high, due to the
fact that the winding convolutions are
arranged shoulder to shoulder.
PIE WINDING is BETTER.
The pie-wound inductancc. so called
from the fact that the winding Is d.
yided into flat sections or pies AaS
somewhat lower distributed capacity
losses. because Of breaking the wind
ings mn into sections. This gain IN et'
ficicncy is offset in some forms ot IN.
ducfance by the fact that the pics, oil
fhe coils are placed so close together
that the seIf-capacity coils themselves
is higher than the inefficient layer
wound coils.
A further improvement in coil de-
sign is the bank-wound inductance'
This is constructed by winding on q
few turns, such as in the lager-wound
coil, then bringing the wire back and
winding over the wires first wound
on. The self-capacity Of the coil is
grcatly reduced by breaking up the
winding cOnvolutions.
The lateral, or stagger type Of wind
inzs. IN which the wires are as little
parallel to one another as possible, al
lords a very efficient method OF OBJ
tanning inductance with minimum loss
Is. Mechanical difficulties are encoun'
