inside your radio you probably haven't 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 script and other writers handle publish city needle is then material for special regional and farm programs news commentators broadcast stories gathered from all corners of the world often analyzing important events and expressing their own opinions regarding them for 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 sound effects  realism to dramatic programs and are produced by specialists in a small already very interesting field actors and actresses prefer them for on the scene audiences and compare them and skillfully operate the apparatus which mixes sound effects music and dialogue the best the world has to offer in music rama and comedy may be enjoyed in one's own home or radio his greatest application is in broadcasting mass entertainment many programmes are broadcast over radio networks and telephone lines are employed to connect the studio with the various stations as a program they originate in a studio in 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 lines which have been set up in advance i connected to feed the program to the network stations the maintenance of radio broadcasting equipment and ploys 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 attained 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 men to become a radio engineer without training in a first class engineering school radio manufacturing and general is classified  skilled work as most of the jobs can be mastered in a very short time many women are employed assembling and inspecting radios as the work is not heavy on their early such rug does not lead to responsible positions and should be avoided unless one will be satisfied with employment in manufacturing however men with screening are sometimes placed in the production of five months 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 s this is created a large field of employment however the supply of radio service men generally exceeds the need and this makes a big screen a difficulty for any but the well trained to succeed in the work often the most successful radio dealers and salesman i was always who can talk with authority about the products they sell frequently because they have had practical experience in radio repair work the radio service field is not a good stepping stone to the 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 radio stations on land the operator is delaying the station's thens and receives commercial messages handles weather reports and listens for distress signals from ships at sea air travel has become state today largely because of the application of d o principle 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 lending 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 the 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 the sound movie through the use of microphone and full of fire and vacuum tube the sound for motion pictures is photographically recorded on the edge of the film to  soundtrack when the soundtrack which is the thousands of theatres it is reproduced by means of the photoelectric cells are electric guy and full of fires and a loud speaker system maintenance men with fundamental knowledge of radio think meek constantly employed to keep this delicate equipment in working on public address systems also use some of the principles of radio they range from the temporary and portable unit permanent installations in large auditorium and many operators of probable public address systems on their own equipment which is in demand that 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 large permanent public address system but this work  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 newspapers subscribing to the service get the photographs 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  from the scene of action cameramen televised events which you may see in your own home if 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 hardware guy 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 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 ime are you sure that after school authorities to help you investigate any school residence or a correspondence which you may plan to attend your high school preparation for entrance into radio must lay a strong foundation in science and mathematics the basis of all engineering and especially about electrical engineering you must in addition develop a high degree of coordination between hand in mine 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 basic theory and practical operation it will show your mettle quickly than anything else whether or not you can succeed in radio
