BASIC RADIO PRODUCTION: LECTURE NOTE 1

1.       INTRODUCTION: RADIO HISTORY

Radio involves the process by which messages are sent through electrical waves. In other words, sound would be sent and received through the waves (Sambe, 2008:75). The history of Radio dates back to the 19th Century when Samuel Morse invented the electric telegraph. According to Bittner (1989:93), Gugielmo Marconi built on this invention to produce electromagnetic impulses which would be sent through the air without the use of wires. The voice was carried over long distances.

Thus in 1866, signals were transmitted from England to America without wires. Sambe (2008:75) states that, in 1888, Heinrick Hertz, working on the electromagnetic theory propounded earlier by a British scientist James Clark Maxwell, produced the first radio waves.

2.       ADVENT OF RADIO IN NIGERIA

In Nigeria, radio started with the introduction of the Radio Distribution System in the year 1933 in Lagos by the British colonial government under the Department of Post and Telegraphs (P&T), according to Idebi (2008,P.3). The Radio Distribution System (RDS) was a reception base for the British Broadcasting Corporation and a relay station, through wire systems, with loudspeakers at the listening end. In 1935, the Radio Distribution System was changed to Radio Diffusion system. The aim was to spread the efforts of Britain and her allies during the Second World War through the BBC. The Ibadan station was commissioned in 1939, followed by the Kano station in 1944. Later, a re-appraisal of radio broadcast objectives gave birth to the establishment in 1950 of the Nigerian Broadcasting Service (NBS). The NBS began broadcast in Lagos, Ibadan, Kaduna, Kano and Enugu on short wave and medium wave transmitters. Through a Bill by the House of Representatives, the Nigerian Broadcasting Corporation (NBC) was established in 1956. The NBC took up the responsibilities of radio broadcast in Nigeria. The Federal Radio Corporation of Nigeria (FRCN) was established in 1978. The Voice of Nigeria (VON) which served as the external service was established in 1990. With the creation of more states and each state wanting to propagate its people and culture, the pace for radio broadcast began in Nigeria and has spread fast across the length and breadth of the nation. Each state owns and operates at last one radio station.

3.       CHARACTERISTICS OF RADIO

         i.             Radio makes pictures: When you listen to a commentary on radio of football match.   As you heard the commentary, you could visualize or ‘see’ in your mind what was being described. You could actively ‘see’ pictures in your mind of the footballers even as you listened to the sounds of fans singing or the sounds of the referee’s whistle. You use your power of imagination as you follow the running commentary.

        ii.            Fast medium: Radio is the fastest medium. It is instant. As things happen in a studio or outside, messages can be sent or broadcast. These messages can be picked up by anyone who has a radio set or receiver which is tuned into a radio station. If you have a television set and cable or satellite connection you may be using a remote to get your favourite channel.

      iii.            Simple medium: Compared to all other media, radio is simple to use. As mentioned in the previous sections, radio needs very simple technology and equipment.

      iv.            Inexpensive medium: Radio is inexpensive: As it is simple, it is also a cheaper medium. The cost of production is low and a small radio can be bought for as low a price as say three hundred naira

       v.            Portable medium: Don’t you move your radio set at home from the living room to the kitchen or as you go out somewhere? You can’t do that very easily with television. This facility of moving an object which is called ‘portability’ gives radio an advantage. These days if you have a car and a radio in it, you can listen to it as you drive or travel. Can you think of watching television, when you drive?

      vi.            One does not have to be literate to listen to radio: Unless you are literate, you can’t read a newspaper or read captions or text on television. But for listening to radio, you need not be literate at all. You can listen to programmes or news in any language on the radio.

4.       OBJECTIVES OF RADIO

Ø  to inform

Ø  to educate inter related

Ø  to entertain

5.       LIMITATIONS OF RADIO

Ø  One chance medium: When you read a newspaper, you can keep it with you and read it again. You have the printed word there and unless the paper is destroyed it will remain with you. Suppose when you read a news item, you do not understand the meaning of certain words. You can refer to a dictionary or ask someone who knows to find out the meaning.

Ø  Radio has no visual images: Let us consider a news item on radio and the same item on television. For example, the news about the devastating 9/11 attack that hits World Trade Centre. Radio news talked about the intensity of the attack, the number of deaths, details about property destroyed etc. However in the case of television, it showed the actual planes hitting the twin towers, visuals of properties destroyed, rescue operations and many more details which could be seen.

Ø  Messages on radio are easily forgotten: The problem of not having visuals leads to another limitation of radio. What is seen is often remembered and may remain with us. For example if you have seen the fine visuals of the Taj Mahal in Agra, it will remain in your memory. But what you hear is normally forgotten fast. Probably you may remember what you have heard in a class room if you found it interesting. But can you recall all the headlines of a news bulletin you heard on radio? Normally, you don’t. So this is another limitation of radio.

Ø  Poor performance on the part of announcers: Presenters or participants in a radio programme can be boring or uninteresting that it can result in listeners switching off their radio sets. So listeners’ interest depends up on how information or messages are presented.

Ø  Radio broadcasts are of no use to people who have no sense of hearing especially those with hearing disabilities.

6.       RADIO FREQUENCIES

Radio frequency (RF) is a rate of oscillation in the range of about 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals. RF usually refers to electrical rather than mechanical oscillations; however, mechanical RF systems do exist.

Frequency	Wavelength	Designation	Abbreviation
3 – 30 Hz	104 – 105 km	Extremely low frequency	ELF
30 – 300 Hz	103 – 104 km	Super low frequency	SLF
300 – 3000 Hz	100 – 103 km	Ultra low frequency	ULF
3 – 30 kHz	10 – 100 km	Very low frequency	VLF
30 – 300 kHz	1 – 10 km	Low frequency	LF
300 kHz – 3 MHz	100 m – 1 km	Medium frequency	MF
3 – 30 MHz	10 – 100 m	High frequency	HF
30 – 300 MHz	1 – 10 m	Very high frequency	VHF
300 MHz – 3 GHz	10 cm – 1 m	Ultra high frequency	UHF
3 – 30 GHz	1 – 10 cm	Super high frequency	SHF
30 – 300 GHz	1 mm – 1 cm	Extremely high frequency	EHF
300 GHz - 3000 GHz	0.1 mm - 1 mm	Tremendously high frequency	THF

7.       RADIO PRODUCTION TEAM

Radio production team or crew are the group of skilled and unskilled personnel that make production possible; some of the radio production team include:

1)      Station Manager: Station Managers are responsible for the day-to-day running of Radio stations - leading the management team to ensure they meet the key objectives of the station in terms of output, audience, or revenue. In Commercial radio the job title Station Director may also be used in reference to the manager of a local or national station. In some organisations a Regional Director may have responsibility for more than one station. Most stations also have a Programme Controller (link) or Programme Director.

2)      Programme Director: the responsibility of a programme Director in any radio station is to direct and coordinate daily radio station operations. She/he also develops, schedules and supervises production, recording, and airing of all programs. Additional information available includes essential job functions, additional responsibilities, and education and experience requirements.

3)      Programme Manager: In radio, a program manager/director or director of programming is the person who develops or selects some or all of the content that will be broadcast. A program director's selections’ are based upon expertise in the media as well as knowledge of the target demographic. Typically, a program director decides what radio program will be broadcast and when.

Studio Manager: In a broadcasting context, a studio manager, or SM, fulfills an operational role in radio broadcasting to enable and ensure programmes are produced to a high technical standard. The following are some of the responsibilities of a studio manager:

• Workload dispatch
• Compiling studio schedules for senior management meetings
• Compiling Road map for projects
• Constant update of Studio schedules
• Designer’s annual leaves coordination
• Prompt timesheet collection
• Understanding of how deadlines work

4)      Executive Producer: An executive producer is the head producer who oversees the creation of a radio broadcast, music album or theater performance. An executive producer usually works for a production company, but may work independently. Executive producers work on the business side of production. They ensure that a production meets goals, such as helping the station to remain competitive, projecting the intended brand image of a company and introducing new concepts or ideas.

5)      Producer: Radio Producers work in both speech-based and music Radio. Although they play a key role in creating what is heard by listeners, they are not usually heard on air themselves. They are responsible for creating and co-ordinating the content of Radio programmes, and may also have responsibility for the content of related websites or other mobile platforms. As well as managing the creative process they are often closely involved with the business and technical aspects of programmes.

6)      Microphone Operator: Set up, operates, and maintains the electronic equipment used to transmit radio programs. Control audio equipment to regulate volume level and quality of sound during radio and television broadcasts. Some of the responsibilities of microphone operators include:

Ø  Report equipment problems, ensure that repairs are made, and make emergency repairs to equipment when necessary and possible.

Ø  Observe monitors and converse with station personnel to determine audio levels and to ascertain that programs are airing.

Ø  Monitor strength, clarity, and reliability of incoming and outgoing signals, and adjust equipment as necessary to maintain quality broadcasts.

Ø  Control audio equipment to regulate the volume and sound quality during radio broadcasts.

Ø  Monitor and log transmitter readings.

·Play and record broadcast programs using automation systems.

·Align antennae with receiving dishes to obtain the clearest signal for transmission of broadcasts from field locations.

·Set-up, operate, and maintain broadcast station computers and networks.

·Preview scheduled programs to ensure that signals are functioning and programs are ready for transmission.

·Maintain programming logs, as required by station management and the Federal Communications Commission.

·Select sources from which programming will be received, or through which programming will be transmitted.

·Install broadcast equipment, troubleshoot equipment problems and perform maintenance or minor repairs using hand tools.

·Determine the number, type, and approximate location of microphones needed for best sound recording or transmission quality, and position them appropriately.

·Record sound onto tape or film for radio or television, checking its quality and making adjustments where necessary.

·Edit broadcast material electronically, using computers.

·Substitute programs in cases where signals fail.

·Set up and operate portable field transmission equipment outside the studio.

·Schedule programming, or read television programming logs to determine which programs are to be recorded or aired.

·Organize recording sessions, and prepare areas such as radio booths and television stations for recording.

·Make commercial dubs.

·Design and modify equipment to employer specifications.

·Regulate the fidelity, brightness, and contrast of video transmissions, using video console control panels.

·Give technical directions to other personnel during filming.

·Instruct trainees in how to use television production equipment, how to film events, and how to copy and edit graphics or sound onto videotape.

·Discuss production requirements with clients.

·Produce graphics for broadcasts.

·Prepare reports outlining past and future programs, including content.

·Develop employee work schedules.

·Produce educational and training films and videotapes by performing activities such as selecting equipment and preparing scripts.

7)      Artists/Characters: Performers entertain audiences. They may inform or educate them, move them to laughter, or to tears. They contribute their various skills and talents to a variety of genres, including Television, Film, Theatre, Radio and other media. Professional Performers are trained, paid for their work, and must fulfil their contractual obligations, as opposed to amateur performers who take part for fun, and without payment. Personality is central to Performers' roles; they need to be able to relate to their audiences, and involve them in their performances.

8)      Continuity Announcer: a person on radio who makes linking announcements between programmes to give continuity to a radio broadcast channel. continuity announcers are people who are employed to introduce programmes on radio network, to promote forthcoming programmes on the station, to cross-promote programmes on the broadcaster's other stations where applicable and, sometimes, to provide information relating to the programme just broadcast.

9)      Newscaster:  A news presenter (also known as newsreader,  newscaster,  anchorman  or anchorwoman, news anchor or simply anchor) is a person who presents news during a news program on the radio. A newscaster (short for "news broadcaster") is a presenter of news bulletins. This person may be working in the field of broadcast journalism as a journalist and electronic news gathering (ENG).

10)  Editor: A person who edits is called an editor. By editing, we mean preparing a news report for publication, telecast or broadcast. Editing is a process by which a report is read, corrected, modified, value-added, polished, improved and made better for publication. Condensation is also part of editing.
