The secondary coil is one on any re-

It is feasible to use the same bat-

ferent sets. Separate B batteries
should be used.
\V'hilo the method of using several
sets on one antenna works well when
each set is tuned to a different sta-
tion. it does not permit listening to

Receiving Sets
I
By CARLTON E. BUTLER.
Radio Engineer. ‘
A very serious source of distortion
in broadcast rcception.~cspeclally be-
fore the new allocation if wave-
lengths. but ever present e to the
great number or broadcasting sta-
tions operating in such a. narrow
band of wavelengths. is the hetro- ‘
dvntng of two broadcasting stations.
one on another.
\Vhen two stations are very close
together in wavelength the carrier
wave of one will hetrodyne the music
from the other station so that you
will receive only a garbled program
from either one. It will be impOssl-
bio for you to clear up either station.
The ever increasing source of dis~
tortion. that of reradlatinz receiving
sets, is causing more trouble than all
other sources combined. “’hen a re-
rmliating receiver is tuned in on the
wavelength of a. distant station the
liclrodyno action is the same as if
two broadcasting stations were trans.-
mitting on nearly the same wave-
length.
Your results will be practically the
same. You will receivo a. seriesmf
bubbly notes and occasional trag-
mcnts of words from the program.
but that is all. The Ten Command-
ments should be increased to include.
"Thou shall not disturb thy neigh-
bor's favorite concert with uncalled
for noises from thy punk receiving
set." ‘ . ‘
There is a growing impression that
Federal legislation will soon be en—
acted to prevent the operation of re-
radiating receivers. England has
such a law at the present time. But.
like the‘ Eighteenth amendment to
the Constitution. it may be very diffi—
cult to enforce.
The solution to the problem of re-
rarliating receivers is for the \rallio
public to voluntarily discard their
present sets, it they are of the re-
radiuting type. or change them over
to tho non-oscillating. non-regenera-
tivo typo. Similar changes have oc-
cured before in radio without the
need of. a law. such as the rapid
change from spark to CW transmilo
slon by the amateurs. But a short
time would be required to accomplish
the same thing with receiving sets.
once the more efficient, non-rerndl-
mini: receiver becomes well known.

Aim of Radio
The outstanding need of radio to-
day, both for the" enjoyment of the
art and to promote its further de—
velopment as a. sound industry. is
more efficient amplification.
Not only research engineers but
manufacturers agree that the wider
use of better amplification is the
next stage of development of the
utility. This will not only vastly in.
crease the number or radio users.
but immeasurably improve the
standard and quality of results ob-
tained in homes throughout the land.
To be sure, amplification is al-
ready used with a vengeance. Venge-
ance is often the precise word! Too
much or it‘sounds "keen-alley cat

amplifiers there are transformers
