If inside your radio you probably haven't perhaps you've taken the tubes out to
test them the vacuum tube makes it possible to transmit sound whether by radio a
loud speaker system
or a motion picture projector to has been responsible for the growth of radio into
a business involving land millions of dollars
and I can a business radio broadcasting employees a great many people in general
office work actors correspondents do not prefers file clerks and bookkeepers
and executives
and managers of special departments salesmen who sell time on the air to
advertisers expert to select the talent for programs are all a necessary part of
radio broadcasting continuity writers prepared script
and other writers handle publish city need a ruse
and material for a special mission
or land farm program news commentators broadcast stories gathered from all corners
of the world often analyzing important events
and expressing their own opinions regarding them for a regularly scheduled programs
the production department has a multitude of duties to perform primarily concerned
with planning and preparing the programs to go on the air sounded thinks
that relies into a dramatic programs
and are produced by specialists in a small already very interesting field actors
and actresses preparing for on the scene audiences and can kratom
and skillfully operate the apparatus which mixes sound effects music

Rama and comedy and they be enjoyed in one's own home
or radio his greatest application is in broadcasting mass entertainment many
programs are broadcast over Radio Networks and telephone line.
They're employed to connect the studio with the various stations as a program they
originate in a studio at New York
or Hollywood the use of telephone wires makes it possible for the stations
thousands of miles away to broadcast the program.
The master controls are operated by
and then who have advanced from the ranks their work requires perfect coordination
of mind in hand for a station walk ups must be made on the split second during the
shot period allowed for station identification telephone mines which have been set
up in advance.
I connected to feed the program to the network stations the maintenance of radio
broadcasting equipment
and floor is a large number of workers known as technicians it is their job to see
that the apparatus is kept in perfect working order in the stations we find these
men at work on the amplifiers and on the power equipment.
They are not developing new methods or devices
but I'm maintaining those which have already been developed by the engineer radio
engineers
and then technically trained in the field of electrical engineering as applied to
radio and communications they have brought about the high degree of perfection.
Now retained both in broadcasting equipment
and in radio receiving thinks this work of improvement
and development is continually being carried on by the relatively small number of
highly trained specialists who ride a regular engineers theirs are among the top
positions in radio.
These positions have been filled by men without professional training
but today there is little chance for a man to become a radio engineer without
training in a first class engineering school.
Writing on manufacturing in general is classified as empty field work because most
of the jobs can be mastered in a very short time. Many women are and.
And assembling
and inspecting radios as the work is not heavy on their lay such work does not lead
to responsible positions
and should be avoided unless one would be satisfied with employment in
manufacturing.
However none with training are sometimes placed in the production apartments of
radio manufacturing plants to gain practical experience this wreck serves on so as
a proving ground for these men
and those who qualify in the advanced positions of greater responsibility because
radio broadcasts are so popular the public demands prompt
and efficient repair service to radio sets this has created a large field of
employment. However the supply of radio service men generally exceeds the need
and this makes it extremely difficult for any
but the well trained to succeed in the work on the most successful radio dealers
and the salesman.
I don't work who can talk with authority about the products they sell frequently
because they have had practical experience and radio repair work.
The radio service field is not a good stepping stone to the radio engineer's job
and that's with Hispano
that are accompanied by technical engineering training a very interesting field of
work is that of the radio operator who sends
and receives messages he must be able to send
and receive the international most code
and a specified number of words per minute granting of the commercial operators
license is based on a rigid government examination conducted by the Federal
Communications Commission
and it must be renewed periodic late radio operators are found on practically zero
large ships they communicate with other ships and with the radio stations on land.
The operator of the land stations sends
and receives commercial messages handles weather reports
and listens for distress signals from ships at sea.
Air travel has become say today largely because of the application of radio
principles on commercial airlines the licensed pilots must be radio operators in
addition to flying the plane.
They must report their positions and get their bearings weather information
and landing instructions from the radio operators at the ground station the ground
station operator does not have to be an aviator.
In addition to handling messages free of radio
and how to make minor repairs in order to keep a station on the air the operators
work is to maintain contact with planes in flight as well as to communicate with
other ramparts regarding schedules passenger reservations and weather conditions
and then with radio training often find employment
and Allied lines using basic radio principles among these is a sound movie
through the use of microphone employ a fire
and vacuum tube the sound for motion pictures is photographically recorded on the
edge of the film to put on the soundtrack.
When the soundtrack which is the thousands of theatres.
It is reproduced by means the photoelectric cells are electric guy
and full of fires
and a loud speaker system maintenance men with fundamental knowledge of radio
technique are constantly employed to keep this delicate equipment in working order
public address systems also use some of the principles of radio.
They range from the temporary
and portable unit to permanent installations in large auditorium.
And many operators of probable public address systems on their own equipment which
is then demanded county fairs sporting events political rallies
and conventions this type of work requires some special training
but the feel is so crowded that it offers fewer really good jobs.
The better jobs are there was planning and installing the loud.
Permanent public address system
but this work week was the thorough background in radio
and acoustical engineering another field requiring thermal engineering training is
the transmission of photographs by wire
and radio news services maintain photo transmitters at strategic points
and the newspaper subscribing to the service gets a photograph over receiving
instruments in their own offices television the baby of the radio family is
creating openings for experienced engineers most of whom are graduating from radio
work from the scene of action cameramen televised events which you may see in your
own home if of course you have a television receiver television is opening up a new
field as does any new development.
It is furnishing employment for men who design operate install
and service the transmitters and receivers.
But men with the radio experience especially those who have prepared themselves
through study
and application are given preference specialized training study
and the hard work are necessary and all the phases of radio in spite of the size
and importance of the radio field. It doesn't have a great opportunity.
Except for those who are able to secure the highly technical training which it
requires the best training is
that obtained on a first class Electrical Engineering School specializing in
communications engineering. If that is impossible.
There are a few vocational
and correspondence schools which offer excellent courses in the theory of radio.
However you should ask your school authorities to help you investigate any school
residence
or correspondence which you may plan to attend your high school preparation for
entrance into radio.
Let's lay a strong foundation in science
and mathematics the basis of all engineering
and especially about electrical engineering. You must in a.
Develop a high degree of coordination between hand in mind because much of the work
is very exacting in nature.
If You probably one of the best ways to get started is to make it a hobby
and build an amateur station. This will give you the chance to put basic theory.
And practical operation. It will show you.
Mal quickly than anything else whether
or not you can succeed in radio.
