Radio broadcasting

To receive and enjoy our quality programs to the fullest, you'll need the three A's of radio:. If you have all three of these, you could potentially receive an FM station up to miles away! However, most of us have, at best, only one of these items. RADIOS: For good reception, a radio must have good selectivity selectivity is a radio's ability to separate weak stations located nearby, on the FM dial, strong stations and good sensitivity the ability to receive weak, distant, stations at all!

Car Radios: You already probably have a radio with these features. This radio is located in your automobile. Car radios have to be built to high standards to provide decent reception in a moving vehicle, in the presence of varying terrain, with a serious nearby source of interference your engine! You've already probably noticed that FM radio reception is usually better in your car than in your house.

This is partially because your car radio is probably better than your home radio. Most clock radios, under kitchen cabinet radios, "boom boxes" , crank-up radios, etc. You can get the same reception in a bad location using a great antenna as you can in a good location using a bad antenna!

But lets work on improving both! They are weakened by objects that get between the transmitter and receiver. The least expensive radios ONLY have built-in antennas, with no provision for connecting an external antenna. With better radios, you have a choice.

The atmosphere is FULL of radiofrequency signals, some of which will conflict with each other. Here's a few examples of types of interference to NCPR we've heard about. Subscribe iTunes RSS. To receive and enjoy our quality programs to the fullest, you'll need the three A's of radio: A good radio A good antenna A good location If you have all three of these, you could potentially receive an FM station up to miles away!

They sound great, and are a quality product. Try connecting a better antenna see below and see how your reception improves! Reviews have stated that this is one of the best tuners ever built! Remember that you have to have an external amplifier and speakers for this one!

The higher up your antenna is located, the better chance you have of receiving a clear signal from NCPR. In other words, if your radio has a built-in antenna, it will work better in your attic, than in your basement! Or if you have an outdoor antenna, it will perform better on the roof, than on your kid's old swing-set. If your house is on a hill, you'll get better reception than if it is in a valley.

A "walkman" or iPod with an FM radio uses the headphone cord as the antenna! Except in strong signal areas nearby a transmitter none of these perform very well. Signals they receive are usually variable; for example, when you walk around the room, the signal strength will change usually for the worse!

Wire "dipole" usually supplied with better radios : This is a flexible wire antenna that comes packed with some radios, including the few I recommended earlier. It is also somewhat directional; it will in theory pick up radio stations better perpendicular to the horizontal portion of the "T". So if you listen to several stations broadcasting from different directions this might not be ideal.

These perform somewhat better than the wire "dipoles" because you can move the one or two rods around for optimal performance. Circular, ash-tray sized and other types of indoor antennas are meant for UHF television and won't work very will with an FM radio.

Amplified indoor antennas: People ask me every day well maybe every few months about these things. Technically there are several things wrong with this approach. Typically your radio already has a very good pre-amplifier built in to its circuitry. A "dipole" antenna connected to your radio should work just as well as an amplified antenna if your radio isn't somehow "reception challenged" that is!

The additional pre-amplification sometimes causes increased noise in the reception, especially if there are strong FM stations in the neighborhood and you're trying to receive a weak one! On the other hand, if you can't have an outdoor antenna, and an indoor dipole or pair of "rabbit ears" is too unsightly, then a slick-looking indoor antenna might be the best for you.

However, I don't think it will "work wonders" with your FM reception. Let me know how they work for you. Email radiobob ncpr. Apartment dwellers, renters, cave-dwellers, submarine operators. I'm sorry, as I know you probably can't install an outdoor antenna. The best thing for the rest of us to do is to use or re-purpose a TV antenna that's already on your roof. You'll be surprised at how well this works!

If you want to install a new outdoor FM antenna, there are two types to choose from, "omni-directional" and "directional". This is a decent choice if you like to station-hop. If you mostly listen to only one station NCPR perhaps? Installing an outdoor antenna can be fun, challenging, or both!

Here's how: The easiest way to do this, is to have someone else do the installation. Hit the Yellow Pages or ask around. To do it yourself, "somehow" mount your new FM antenna on a metal pipe. Somehow, secure the pipe to the roof or side of your house remember the higher the better! You can get tripod roof mounts and wall mounts from Radio Shack as well as antenna mast.

Then you need to somehow get the signal from your antenna down to your radio. Now everybody uses round coaxial cable. Your new antenna will probably have two screw terminals on it, so you'll need a coaxial "balun" or matching transformer to connect to this type of antenna. The matching transformer will have an "F" connector on the end away from the antenna. You can purchase coaxial cable with mating "F" connectors already installed, or purchase a special crimp tool and install your own "F" connectors on coaxial cable you purchase separately.

Route the coaxial cable through the cellar, etc to the radio. I didn't mention interference! However, as adults, we should at least discuss it The atmosphere is FULL of radiofrequency signals, some of which will conflict with each other. In theory, this sounds perfectly acceptable, however several things can go wrong: Some of these units weren't designed properly and they broadcast over a MUCH wider area than they should.

Some of these devices come pre-set to broadcast on Also, if improperly installed, some of these devices can cause tremendous areas of interference! You will probably notice this type of interference while driving. All of a sudden, Howard Stern will override your Morning Edition!

What to do? Or if you happen to repeatedly see the same vehicle producing the same interference to your radio, you might ask the owner to switch the output frequency of his device. Interference from other stations: Typically this can be cured through the use of a radio with better selectivity.

If you hear another station while trying to listen to NCPR, try listening on another radio a car radio, for example. If the situation improves, you probably need a better radio. If you can somehow increase the amount of NCPR signal while decreasing the offending signal then your radio will be able to separate the two stations better. Multi-path interference: Sometimes the same FM signal can be received by your radio's antenna from several different places, at slightly different times!

For example, if there is a nearby reflective surface like a cliff face the signal might arrive at your antenna directly from the NCPR transmitter, then a fraction of a second later after it has "bounced" off the rock cliff face.

The radio becomes "confused" and noisy, harsh reception can occur. To cure this, try to either use a directional antenna, or try to re-orient your antenna to maximize your reception. Other sources of interference: There are plenty of other sources of interference possible, amateur radio operators talk to them , computers, TV's, fluorescent lights, electric fences. Try to determine which of these sources is causing the problem and isolate it.

Get a better antenna or a better location for it. NCPR is supported by:. Boston Acoustics Horizon Solo. Boston Acoustics Horizon Duo. Tivoli Model One. Sangean WR A radio with a built-in antenna.

Linking Generations Through Radio

University of California Pr Bolero Ozon. Alaina Lemon. The nightmare shades of mind control and crowd frenzy have long alternated with the pastels of love and collective effervescence. Both extremes materialized over time, along tangled circuits of wars, events and interactions staged across borders since at least the 19th century. The Cold War and its fences fed fascination with the workings and the failures of contact and communication. Opposed sides accused each other of jamming media and spinning propaganda even while they mirrored fantasies of connection. This book contrasts and connects Russian and American channels and means to check channels, with special attention to intersections of the telepathic with the theatrical. It theorizes links between historically layered struggles over technologies for intuition and dominant models of communication, commonsense or theoretical.

The Radio Handbook is a comprehensive guide to radio broadcasting in Britain. Featuring two entirely new chapters for this edition, You Radio and Sport on Radio, this text offers a thorough introduction to radio in the twenty-first century. Using new examples, case studies and illustrations, it examines the various components that make radio, from music selection to news presentation, and from phone-ins to sport programmes.

Radio is the technology of signaling and communicating using radio waves. They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by a radio receiver connected to another antenna. Radio is very widely used in modern technology, in radio communication, radar , radio navigation , remote control , remote sensing and other applications. In radio communication , used in radio and television broadcasting , cell phones , two-way radios , wireless networking and satellite communication among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal impressing an information signal on the radio wave by varying some aspect of the wave in the transmitter. In radar , used to locate and track objects like aircraft, ships, spacecraft and missiles, a beam of radio waves emitted by a radar transmitter reflects off the target object, and the reflected waves reveal the object's location. In radio navigation systems such as GPS and VOR , a mobile receiver receives radio signals from navigational radio beacons whose position is known, and by precisely measuring the arrival time of the radio waves the receiver can calculate its position on Earth.

May 11, - UNESCO's radio toolkit – Linking Generations through Radio – is an open access and several radio stations in Africa have more than a million listeners each. and an advocacy tool to inform policy makers as well as the general public. It provides a space for new ways of radio production, new voices.

Radio , sound communication by radio wave s, usually through the transmission of music , news, and other types of programs from single broadcast stations to multitudes of individual listeners equipped with radio receivers. From its birth early in the 20th century, broadcast radio astonished and delighted the public by providing news and entertainment with an immediacy never before thought possible. Broadcast radio remained the most widely available electronic mass medium in the world, though its importance in modern life did not match that of television, and in the early 21st century it faced yet more competitive pressure from digital satellite - and Internet -based audio services.

Radio broadcasting is transmission of audio sometimes with related metadata by radio waves intended to reach a wide audience. Stations can be linked in radio networks to broadcast a common radio format , either in broadcast syndication or simulcast or both. Signals can be either analog audio or digital audio. Television broadcasting also uses radio frequencies, but includes video signals.

The oldest document Ina has in its collections is a recording of the voice of Gustave Eiffel, which dates from , but radio-related collections date mainly from Several radio collections from various radio production companies and private radio stations have been acquired by or given to Ina as a donation. The collection was built up thanks to donations and contains not only recordings in a variety of formats, but also, some precious written documents.
