O, Can a counterpoise be shorter
than the aerial? will It give bet
ter results than a .ground7 II l
make a counterpoise like the one
shown in my letter will 1t be all
right? Is a fan counterpoise better?
CDQ.
A. The counterpoise shoufd have
more wiresthan the aerial. although
1t is best to experiment little.
The counterpoise shown in your let
ter might work all right, but ran
counterpoise would probably be bet
ter. For transmitting II Is much
better than a ground.
O. will be able to hear WIZ on
a four-wire aerial twenty -hve feet
long and twenty feet high with
iris set? w. B.
A Your aerial Is too short and
too low for proper reception OF WIZ.
O. What is the standard code in
use at the present time? Is there
such a station as KYW. and where
Is 1t located, and what Is its wave
length? How can I make a loud
talker for a De Forest Everymans
set that will enable everyone in the
room to listen to the music?
A Tho code used at present Us
Continental. KYW IL located In
Chicago. You cannot make loud
talker that will work with a crystal
set.
O. How can I add to a Marvel
or Aeriola, jr., receiving set: Can
I hear WIZ and WDY with a small
set with an aerial 100 feet long
and no variable condenser? Please
tell me how I can improve this set
without the addition OF an audion?
S.M.L.
A. It is best not to try to i'm
prove a set that has been designed
for a certain service. As you do
not tell the height of your aerial
it is dificult to say IL you will be
able to hear the broadcasting with
the set that was in this paper.
O. Is a long single wire aerial
better than a short double wire? Is
it all right to use bare copper wire
as the lead to the ground connec-
ton? II there are two aerials on
the same roof separated by about
10 feet should they be at right
angles to each other? G. H.
A The long single wire aerial is
the best for receiving. The wire
mentioned in your letter will be all
right for the ground lead. II the
two aerials you mention are both
used for receiving they do not have
to be at right angles to each other.
II they are used for transmitting
you will experience a lot of trouble
while the other fellow is using his
transmitter as you will not be able
to tune him out
Q. have a 200-foot aerial on the
roof that Is in the shape of an l..
II I had it arranged differently
could I get better results? Can two
sets of receivers be attached TO the
same set without weakening the
tone any? ]. w. Il.
A. Your aerial is all right the
way it Is. You can connect more
than one pair of receivers to the
same set without detrimental ef-
fects.
Q. Will you please tell me what
three coils are necessary 10 use IN
triple coil honey-comb mountings?
w. ].
A. You will need an l. 35 primary,
L so secondary and either L so or
L rs for tickler.
Q. Will you please tell me II I
can use the enclosed hook-up for
receiving the music? What is the
difference between damped and un-
damped waves? J.. r.
A. The closed audion circuit will
work very well for the reception
of music. but you will not be able
to tune very sharply. Some form
of loose coupling will give better
results. Damped waves are those
that are given out by spark set
and they are called damped because
the wave train is rapidly damped
out. Undamped waves are given
out by C. w. or arc sets and are
called so because the wave train is
MT danoned aut or dfminished
