would be fewer, and that mean
very few radio stations on the fire.

Beat The Band
Amplitude incubation did not re
quire the wide band, therefore
more stations could be accomo
dated needless to say tina
those were the days when radio
frequencies were not SO importan
in fact they were not SO wei
known -. and when A. M. did no
pass the audio range, padding wa.
resorted to and for years expert
mentation was the order of the day
always however the narrow
band was the limiting factor anc
elaborate padding was required tt

range required =. so now it's F

most it is the elimination of ex.
traneous noise in your radio re-
ceiver theoretically, if you
get the station, you get the pro.
gram and nothing else, you gel
your music-all of your music, yes
from way down around Is cycles
to way up above twelve thousand
cycles, and that is really getting
audio frequencies.
Swept And Low
In practice we have found that
there are extraneous noises some.
time . for instance ignition sys-
TENS on autos have caused inter.
ference and sometimes we have
noticed static where static wasn't
supposed to be i. 81. then too, what
about the audio range, when you
begin listening to frequencies over
seven thousand cycles you be-
gin to hear the scratch on records
very plainly, you hear the scratch
of the bow on violin string along
with the tone itself {. of course
this will be entirely dependent upon
the Individual human ear be-
cause there are many many hu.
man ears that will not respond to
a frequency of ten thousand cycles
it is generally understood that
FIN will pass the high frequencies
much more readily than A. M. :.
getting Kind of technical Ell.
i. =. when you raise or lower a
tone you have an entirely different,
one, right? F.. when we use tone
and make that tone more or less
prominent in the ensemble and
then compute the entire output in
terms Of gain, which of course is
measured in decibels we in radio
call it attenuation.

Whew, let's change the subject,
of all this talk pro and
con on FIN you are going to like it.
1t is the greatest Improvement in
radio broadcasting since the advent
of vertical recording But let's
hope the manufacturers 60 along
with radio broadcasting, by build
ing receivers which will take ad-
vantage of the great improvement
in audio frequencies, rather than
trying to sell for price alone :.
that's all, hope you're not dizzy, !
