SHORTEN ANTENNA
NEAR BIC STATIONS

When using u medium priced radio
receiver, located for instance in the
heart Of large city and surrounded by
several powerful brOadcastiug sta
tons, the receiver will many times
seemingly display a lack Of both Sc
lectivity and sensitivity. n general,
il has been found that such receivers,
especially when installed By the I'm
initiated, have an antenna much too
long. The length Of an antenna, b.
the way, includes the length Of the
lead-in and ground wire Particularly
Don apartmCnthOuses, one is apt to find
fiat Top antenna 90 or 20 feet long,
with n lead-in attached which runs
from the top Of the house to the first
floor, being invariably 100 70 80 feet
in length. The result is large
amount Of energy is picked up by such
an enormously long antcnna, overload
ing the vacuum tubes. and despite the
efficiency Of the tuning circuits, ex-
tremely poor overall received sclectiV-
ity is obtained.
The solution for such trouble is
usually very simple. The antcnna
should be shortened until its length IS
not over 100 feet, including the length
Of the lcad-in and ground wire. In adj
ditiOn TO this, n fixed condenser hav-
,ng a capacity Of from .OO01 TO .OOO2j
micrOfarads may BE- connected in Sc.
ries with the antruna. This means
that the antenna wire is connected 10
one terminal Of the condenser and the
other terminal Of the condenser is con
nccted with the antenna binding post
on the receiver. A usual grid con-
dcnser may be used for this purpose
very nicely.

VOLTAGE TEST BEST
FOR B BATTERIES

The only test of a "B" battery
which is worth anything is the
voltage test. While battery uSeR
and dealers are in the habit Of test
ing dry batteries with an ammeter,
this test is worthless on a b bat
terry.
The amperage indicates to a GER
tain extent, the internal resistance
of a battery, but since the resist
ance Of a 226-vOlt battery is about
s Ohms, and the resistance Of a
vacuum tube is from 10000 to 80
600 ohms, it Is apparent that an in
crease of say S ohms in the battery
resistance will have no appreciate
effect on the combined 81 battery
and tube circuit.
In other words. a drop in the am
perage of -B- battery, so long a.
the voltage is still satisfactory,
means little regarding the useful
ness Of the battery.
The important thing to know Is
the voltage which the battery will
deliver TO the plate, and the volt
age test is Of real value only when
made with a high grade, accurate
voltmeter.
The reason for this is that the
ordinary pocket yoltmeter has j
much lower resistance than the
vacuum tube. Because Of this the
voltage shown on this type Of volt
meter will be lower than that act
ually delivered TO a tube with its high
resistance.
Furthermore. these vOlemetcrs are
often inaccurate. On the other hand,
a high grade, accurate instrument has
approximately the same resistance as
the vacuum tube and in some cascs
even a greater resistance.
Therefore, it is certain that when
"B" battery indicates g given
voltage on a vOltmeter Of the lat
ter type it will deliver at least as
much voltage to the tube.
The minimum working voltage Of
detectOr tube is about II volts. There
fore, a 1B7 battery should give re-
suits till its voltage drops to this fig
ure. Even then il need not be dis
carded. 1t can be connected in series
with other batteries and used on the
amplifier tube.
Here it should be serviceable until
its voltage has dropped 10 about one
half. In this connection, however.
one thing should be watched. Some
II" batteries become noisy when their
voltage drops and if this is the Gaze
the battery should not be used. This
Is especially true Of b batteries
Of ordinary construction, where no
special pains are taken 70 eliminate
the noise feature.

developments would have been worth
less"
Being as interested as most fans
are in finding out some of the views
of DIR. De Forest on radio of today
and of the future, 1 asked:
do you see a possible combination
of the radio and the photoplay which
will permit a person to sit in their
home and both see and hear play
broadcasted from the central sta
Sion?"
DIR. De Forest replied:
"Not for another twenty years.
Professor jenkins has come nearest to
attainment in his day and age, the
next step for the motion picture l
naturally visualize in my own phono-
film or talking moving picture inven-
tion."
/ asked:
what do you think is the next
step in radio Development"
He replied:
"The next step for radio is beam
transmission for transatlantic and
long distance work with short wave
lengths for broadcasting."
TUBE DEVELOPMENTS.
In a running conversation, DR.. De
Forest included the following views,
which / thought were of extreme in.
terest. He believes he has perfected
loud speaking device which will
prove distinct advance in loud
speaking amplificatiOn, in that it will
equal or surpass the finest of ear
phone reproduction. He believes this
device is non-directional, correcting a
condition which has heretofore caused
much dissatisfaction in a great num-
Der of present-day loud speakers.
He thinks the day is not far OIL
whon the life of a tube will be in
creased to equal that of the present
high Grade incandescent lamps. He
claimed that twenty million homes
do not possess a radio due to lack
of radio conception or inability to
buy one at the prevailing prices. He
thinks the point of saturation in the
radio field is a long way off, but
that newspaper education Of the pub
lie to the point of buying conscious
ness will go n long way toward hast
ening that day.
DIR. De Forest is as emphatic as
ever in his denunciation of using the
air for advertising purposes and feels
that such misuse of wonderful boon
to humanity will boomerang and de-
strCy those employing it.
He asks the American people to
have faith in radio, contending that
this industry, of which he is the
founder, must Of its own accord shake
off the undcsirabIes and carry to the
highest pinnacle of success those mem
bcrs Of it who like himself have been
and are conscicntouslg working for
