You simply find your best signals,
leave the apparatus set that way and
it back and enjoy it for the rest of the
rening.
The fundamental electricity necessary
icr understanding the installation and
vcfking of radio set is no more in.

Understand how your house plumbing
gsem works.
We'll say you have tank or an
incoming supply of water up under the
roof; it Is piped down through the
house, led into certain rooms, turned
on or off with spigots, stored in tubs or
other receptacles by means of shoppers
and, when used. is allowed to escape
through the drains into the sewer under
the house.
Exactly the same thing happens in
wireless set, using electricity instead Of
water.
We are not going to become technical
IN these articles. but we are going to
show now and then how extremely sim
PIE the basic principles of radio are and
We will probably use that house plumb
Ing idea to teach it all the way through.
