in English. The last named station
he also followed for a period of an
hour but has no way of telling where
this. station was as the language
spoken was neither French or Span
ish. Some think 1t was Mexico City.
II anyone else has picked up this
station will they kindly notify this
Office and we IN turn will let Mr..
East Madison has Installed one of the
most up to date radio receiving ont
fits i'm this section of Maine and 1t is
giving splendid service. This was
installed by Mr.. Gardner Mrs. Baker
of Bingham has a splendid radio
get, also installed by Mr.. Gardner and
is made like a photograph, loud
speaker enclosed The Volume is so
great that it can be heard all over
the house.
The editor of this column has had
wonderful results during the past
week with Radiola No. s model,
which he has been temporarily using
for experimental purposes.
Some questions have been asked of
our column this week and the ques-
tIDHS anu dHSWVi oiV huicOy
mitted.
Question No. /. The "B" battery
and its use.
Answer No l. The positive side of
the battery is connected in the plate
circuit. This battery supplies the
current which flows in the phone cir
cult. The increase or reduction of
the current at an audio frequency
produces signals in the telephone.
The positive side of the battery is
connected with the plate.
Question No. g. What is the ac-
ton OF vacuum tube detector in
receiving circuit.
Answer. When the fillament is
burning, electrons are thrown off.
which are attached to the plate due
to the fact that 1t is charged posi-
lively by the battery. A flow of neg
alive electricity is said to flow from
the filament to the plate, but as we
usually consider the current as flow
ing from the positive pole of bat
terry to the negative pole, we consid-
err the current as flowing from the
plate to the filament and thence
through the phones back to the bat
terry Therefore, as long as the
filament is burning there will be a
flow of current thru the phone; but
owing to the fact that II is steady,
there will be no vibration of the dia-
phragm. If oscillations are flowing
in the receiver circuits, alternate
positive and negative charges will be
given to the grid. When the grid
is charged negatively. no current
flows from the grid to the filament
But when the grid Is positively
charged, current passes from he grid
to the filament. In other words.
when the grid is charged negatively,
the electrons will be repealed and no
negative flow of electricity will be
attached and a negative flow to the
grid will take place.
During the time that the grid is
charged negatively no current passes;
therefore, negative charge plies up
in the grid condenser on the side
next to the grid. This negative
charge causes a decrease In the flow
of electrons to the plate and cOnse
quently the flow of current from the
plate to filament is reduced. After a
train of oscillations has passed, the
negative charge leaks off and the
plate current returns to normal
Thus, each train of oscillations re-
duces momentarily the flow of cur
rent through the plate curcuit This
reduction of current causes a click
in the telephone receivers, the num-
Der of clicks per second being depend
ent upon the number of trains of os-
ciliation.
Other questions will be answered
II submitted to r. N. I. r., Independ-
ent-Reporter before Monday morning
of each week.
