10 nine persons out OF ten who get
well into this radio craze and become
what we ordinarily know as bugs"
the mere listening to the broadcasting
concerts has very little thrill and the
great joy Of radio arrives with table,
full Of miscellaneous apparatus, most
OF it probably home- made and not at
all expensive, and scrapbook made
up Of a great collection of diagrams Of
hook ups gathered from dozens of diff
ferent sources.
Operating the radio set then becomes
real Joy.
Not long ago friend Of mine came
to my experimental station four or
FIVE times in one month in order to
listen to radio concert, and each
time he found me in the midst Of un-
hooking my set preparatory to trying
some new arrangement that had come
across.
There is no one hook-u that Is best
for every purpose and aerial and every
location. Whenever you get set that
Is designed to receive everything that
is flying through the ether, you will
know that you have set which has
had to sacrifice a certain amount OF
efficiency somewhere in order to be
generally practicable.
These different hook. ups are not, of
course, of particular interest to the
man who simply wants to hear the
will inevitably later develop into real
bugs. 1t is Just as we'll ut the very
beginning to start making scrapbook
of all the hook k-ups you find and when
your operating room has become clut-
tered up with so much junk that 1t
looks like the sales room of dealer in
| second hand apparatus, you will enter
into the real heaven Of the radio fan
and get the full joy Of this wonderful
new science.
One of my most priced possessions is
a big bundle OF notepaper made up of
the data that I have jotted down night
after night while trying these different
hook ups. give each hook-up in my
scrapbook number and when I sit
down at my table to test it out,
place this number on the top of each
sheet Of the notepaper which Is on my
table, then I rule off columns and lines
and tune In some station. AS soon
rs I get it strongest make a note in
column headed "audibility" Of the
strength with which It comes in.
This audibility scale, which I range
from 0 to 10, cannot be exact, but
1t is near enough to be very interesting,
Under the 0 classification, I place the
station whose call letters can just
barely make out with the aid Of my
imagination and enough sound in th'
telephones to enable me to identify II
after have heard it number of times
Under the 10 classification place
the signals which come in 80 stront
that they actually make the telephones
rattle unpleasantly in the ears. No.
is the signal which comes in will
fairly good satisfaction. Other in.
tcnsities Of sound are graded in between
according to my judgment.
Under other column headings OF
the record I enter the dinl settings o
the various parts as they were whcr
l got best results.
Naturally the usefulness of such ,
system is very largely increased wher
you acquire sufficient acquaintance will
the dot and dash code to enable you Il
identify the many amateur and com
mercial stations which are constant,
working with each other through tn,
ether. And let me say right here tina
1t is worth oil the trouble it requires
to learn this code, because then 20,
can get into the long distance work ant
experience the genuine thrill that Gomez
