When our regenerative receiver is
operated so that the detector tube
oscillates it is pretty sure to be emit~
ting a wave from the antenna. This
radio wove will trsvel to the sur-
rounding receiving aerisls and be
hesrd as a. whistle. When you tune
in on a station your neighbors and
others limening in on the same sts-
tion will hear s. whistle.

Suppose your neighbor dropped in
on you some afternoon and told you
that his car wasn't in working order
because "the clutch back—fired."
You probably would stop him right
there and want to knew just what
he meant by his expression. “\Vcll"
he laid. "the clutch doesn't seem
to take hold properly when I let
out the foot pedal." You would. if
you knew anything about automo-
biles, probably diagnose the trouble
as s ”slipping clutch" and would tell
your friend that that was what his
trouble was. "\Vcll." he said. "you
may call it a. u'slipping clutch" but
when it acts that way I call it a.
backfire." And in spite of all the. ar-
guments you put up as to calling
things by their proper names. he
would go serenely on calling his
"slipping clutch" is "backriring
clutch.“ ,
A parallel case in the radio field
is the tendency to rcfcr to a. receiver
as a. "re-radiating" receiver. You
are frequently told to steer clear of
a. single circuit luncr bccziusc it "re-
radlatcs" very badly. I! is another
case of a trouble being diagnosed as
a "backfiring clutch." Vtht your in-
former mount was that the single
circuit tuner "radiates" Now, as a
matter of fact. the single circuit
tuner. and probably not as bad as
many radio frequency amplifiers, but
in any case the trouble is caused by
"radiation" from (1ch receiver, and
not "re-radiation".
Let us establish the difference
clearly in our minds. Any oscillating
tube circuit is generating high-fre-
quency or radio—frequency currents
and sending them out in the air. “’4:
say Illat tlln act in this case is “ra-
diating" this oncrgy-llmt is. trans-
mitting it. If we use, big tubes in
handle largo amounts of power, We
have a. powerful scnding station. If
we usn our rnccivnr in an oscillullug
condition “'0 :3!” have n‘scnlling ap-

psi-Mus, but transmitting weak sig-
nals. In both cases We have an op-
paratus that "radiates" or sends out
energy. The difference in the two
lies only in the amount of power
used.
Now as to "re-radiation". In the
first place. it you remember any of
your word anslysls from school.
this means "radiating again". In
other words. it means picking up
energy and rte-transmitting. This
phenomenon usually occurs when
we have large metal bodies. like guy
wires or steel chimneys ,steel ting-
poleo or even other antennae in
the very near vicinity of a. powerful
transmitting motion. The metal
guy wires, for instance. pick up a
great deal of the powerful radiated
energy of the «nearby broadcasting
station. In fact they pick up so
much that some oi it leaks off again.
but this time, not , the wave-
length ot the broadcasti station.
but on whatever wovclcn the guy
wire happens to be tuned to. The guy
wire is now "re-radiating" some of
the energy “radiated" by the brand-
casting station.
There is one Very important
thing to remember about “re-radiat-
ed" energy. That is, it is always a
faithful reproduction of the original
signals in all respects. but is “re-
ralllntod' 'on a different wavelength
—tllo wavelength of the guy wire.
for instancc. If the broadcasting
station is transmitting music. tho
guy wirc .antennu or other metal
object will “re-radiate" With por-
foct reproduction the very same
music.
"\Vliisilcs" mean it "radiating" re-
ceiver: not a. "re-radiating" receiv-
“or. Let us all start using the correct
terms when We talk about radio, and
not got in the some class with the
man who had the "backl‘lring
clutch."
