sists of two coils of about four turns
each, one coil on the outside half of
each stator form and two rotor coils
of the same number of turns, one
coil on each half of the rotor FORM
The secondary coil consists of two
coils, one on each inside half of the
stator forms.
Coil Connections Described
One end of the outside stator coil
Ii is connected with the aerial, while
the other end is connected in series
with one of the rotor coils IL. The
other coil, L3, is connected in series
between rotor coil LIZ and other out
side Stator coil LA. The other end
of stator coil Ia is connected with
the ground. The two inside stator
coils are connected in series to form
the secondary winding.
The few turns used on the outside
stator winding of the antenna vario-
meter makes the electrostatic coup
ling between the antenna and grid
circuit negligible. The electromag-
netic coupling between the antenna
and grid circuit can be varied from
almost zero to- between 30 per cent
This fact is of considerable i'm
portance in determining the ability
of receiver to give maximum volume
with greatest selectivity.

TIDE SHOWS EFFECT
ON STATION CAPACITY

WISCASSOT, Me-, September "a
The special amateur radio station,
IMO Installed here by the American
Radio Relay League for the purpose
of establishing communication with
the schooner Bowdoin, which is
bringing Capt. Donald M. Macmillan
home from the Arctic, had not been
in operation more than "a hours De-
fore mysterious changes became no
ticeable in the wave length OF tne
transmitter.
When the sending set was tuned to
a wave length of 165 meters there
would be a variation of eight meters
in a few hours; when it was tuned TO
the short wave of 80 meters there
would be a variation of about three
meters in approximately the same
space of time. This phenomenon con-
tinued. despite all efforts to keep the
oscillator sharply tuned, and anna
teurs with whom the station was in
Communication persistently asked
why the sending wave was being
changed.
The adjustments Of the station
were gone over very carefully sew
eral times and a wavemeter was en-
ployed frequently to check the oscll-
Ia tions. Finally it occurred to Traf-
fice Manager Schnell that, since the
antenna and counterpolse had been
suspended from the dock over the wa
ter. the tide might have something to
do with it.
whereupon he decided to take his
readings with the wavemeter at the
ebh and flow Of the tide and compare
them He discovered that in every
case the wavelength increased with
the rise of the tide and decreased
with the fall. Now in order to keep
the transmitter at a constant wave,
he makes regular adjustments to cor
respond as far as possible with the
tides movements. He declared the
tide changed the capacity OF the sta
tion's counterpoise.

of the regenerative receiver with the
troublesome radiation problem, which
1t introduces, and many proposals
have been made and suggestions
brought forward which have for their
object the elimination of this trouble
some feature of the regenerative re-
ceiver.
From the first it was generally
radio frequency amplification ahead
of the detector and the sacrifice of
the regenerative feature would be the
best solution to a problem which
was growing more and more acute.
Many of the most prominent radio
experts in the country tackled the
problem, with the result that a num-
Der of receivers which eliminate the
radiation nuisance at slightly
greater cost for the receiver, but
with no sacrifice of efficiency, came
to light.
Develops Good Substitute.
AS was foreseen, the best substi-
tute for the highly efficient regenera-
tive receiver proved to be the four
tube receiver, using a stage of radio
frequency amplification, a detector
and two stages of audio frequency
amplification

Film is that viscous coat that you
feel. It clings to teeth, gets into crev-
ices and stays. 1t hides the natural
luster of your teeth.
It also holds food substance which
ferments and causes acid. In contact
with teeth, this acid invites decay.
Millions of germs breed in it. And
they, with tartar, are the chief cause
of pyorrhea.
So dull and dingy teeth mean more
than loss of good appearance. They
