A telephone converts sound, typically and most efficiently the human voice, into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user. The word telephone has been adapted into the vocabulary of many languages. It is derived from the Greek: τῆλε, tēle, far and φωνή, phōnē, voice, together meaning distant voice. First patented in 1876 by Alexander Graham Bell and further developed by many others, the telephone was the first device in history that enabled people to talk directly with each other across large distances. Telephones became rapidly indispensable to businesses, government, and households, and are today some of the most widely used small appliances. The essential elements of a telephone are a microphone (transmitter) to speak into and an earphone (receiver) which reproduces the voice of the distant person. In addition, most telephones contain a ringer which produces a sound to announce an incoming telephone call, and a dial used to enter a telephone number when initiating a call to another telephone. Until approximately the 1970s most telephones used a rotary dial, which was superseded by the modern Touch-Tone push-button dial, first introduced by AT&T in 1963. The receiver and transmitter are usually built into a handset which is held up to the ear and mouth during conversation. The dial may be located either on the handset, or on a base unit to which the handset is connected by a cord containing wires. The transmitter converts the sound waves to electrical signals which are sent through the telephone network to the receiving phone. The receiving telephone converts the signals into audible sound in the receiver, or sometimes a loudspeaker. Telephones are a duplex communications medium, meaning they allow the people on both ends to talk simultaneously. A landline telephone is connected by a pair of wires to the telephone network, while a mobile phone, such as a cellular phone, is portable and communicates with the telephone network by radio transmissions. A cordless telephone has a portable handset which communicates by radio transmission with the handset base station which is connected by wire to the telephone network. The telephone network, consisting of a worldwide net of telephone lines, fiberoptic cables, microwave transmission, cellular networks, communications satellites, and undersea telephone cables connected by switching centers, allows any telephone in the world to communicate with any other...

It consists of two metal plates separated by granules of carbon. One plate is very thin and faces outward, acting as a diaphragm. When sound waves strike this plate, the pressure on the granules changes, which in turn changes the electrical resistance between the plates. Higher pressure lowers the resistance as the granules are pushed closer together. As a steady direct current is passed between the plates, the varying resistance results in a modulation of the current at the same frequency of the impinging sound waves. In telephony, this signal is directly passed through a telephone system to the central office, or it is electronically amplified in other sound systems, such as a public address system or a recording device. The frequency response of the carbon microphone, however, is limited to a narrow range, and the device produces significant electrical noise. Before the proliferation of vacuum tube amplifiers in the 1920s, carbon microphones were the only practical means of obtaining high-level audio signals, and were widely used in telephone systems...

Using a FM transmitter to Repeat an AM Signal in My House
 
01:18
I like listening to AM radio when I'm working at home during the day, but the AM reception in my house is lousy. Here I use a cheap, low-power FM transmitter to transmit AM programming throughout my house. For demonstration, I am transmitting programming via iHeart Radio on my phone, but this can be done just as effectively using an AM signal via a radio. This particular FM transmitter puts out about .5 W. I purchased it from a Chinese seller on eBay. Cost, about $20.

The Father of AM Radio
 
01:53
In the 1890s both Marconi and Tesla were working on developing a method for wireless broadcasting. And both men were focused on transmission of Morse Code, the dots and dashes that were used for the telegraph. Marconi’s radio used a spark-gap generator that broadcasted either a long burst of noise for a dash or a short burst for a dot, as the telegraph key was pressed. These bursts were picked up some distance away by a device called a coherer, essentially a wireless telegraph receiver. Canadian Reginald Fessenden at that time thought that broadcasting should not be limited to the telegraph, which was a soon-to-be obsolete technology. After all, Alexander Graham Bell in 1876 had invented the telephone, which could now transmit voice over wire, and Fessenden thought that both voice and music should also be able to be broadcasted as well. Based on the research of Heinrich Hertz, Fessenden proposed using a high-frequency sine wave carrier signal to amplitude modulate the audio signal, and in doing this, invented AM radio. To receive these AM signals Fessenden used an electrolytic detector, which was a forerunner of a crystal radio receiver. Fessenden called this the “liquid barretter” from a French word meaning exchanger, since it changed the radio signal into sound. Fessenden helped design an alternator-transmitter that was specially built for him by General Electric. Although the frequency and the power output were both less than he had hoped for, on December 21, 1906 he was able to broadcast voice. Three days later on Christmas Eve, he read a passage from the Bible, played a phonograph recording of a Handel piece, and played “O Holy Night” on his violin, making this the first music broadcast.

Crystals Go to War 1943 Reeves Sound Laboratories; Piezoelectric Quartz Crystals for Radio

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://en.wikipedia.org/wiki/Quartz Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Quartz is the second most abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO2. There are many different varieties of quartz, several of which are semi-precious gemstones. Especially in Europe and the Middle East, varieties of quartz have been since antiquity the most commonly used minerals in the making of jewelry and hardstone carvings... Piezoelectricity Quartz crystals have piezoelectric properties; they develop an electric potential upon the application of mechanical stress. An early use of this property of quartz crystals was in phonograph pickups. One of the most common piezoelectric uses of quartz today is as a crystal oscillator. The quartz clock is a familiar device using the mineral. The resonant frequency of a quartz crystal oscillator is changed by mechanically loading it, and this principle is used for very accurate measurements of very small mass changes in the quartz crystal microbalance and in thin-film thickness monitors... http://en.wikipedia.org/wiki/Crystal_oscillator A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is commonly used to keep track of time (as in quartz wristwatches), to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers. The most common type of piezoelectric resonator used is the quartz crystal, so oscillator circuits incorporating them became known as crystal oscillators, but other piezoelectric materials including polycrystalline ceramics are used in similar circuits. Quartz crystals are manufactured for frequencies from a few tens of kilohertz to hundreds of megahertz. More than two billion crystals are manufactured annually. Most are used for consumer devices such as wristwatches, clocks, radios, computers, and cellphones. Quartz crystals are also found inside test and measurement equipment, such as counters, signal generators, and oscilloscopes... Piezoelectricity was discovered by Jacques and Pierre Curie in 1880. Paul Langevin first investigated quartz resonators for use in sonar during World War I. The first crystal-controlled oscillator, using a crystal of Rochelle salt, was built in 1917 and patented in 1918 by Alexander M. Nicholson at Bell Telephone Laboratories, although his priority was disputed by Walter Guyton Cady. Cady built the first quartz crystal oscillator in 1921. Other early innovators in quartz crystal oscillators include G. W. Pierce and Louis Essen. Quartz crystal oscillators were developed for high-stability frequency references during the 1920s and 1930s. Prior to crystals, radio stations controlled their frequency with tuned circuits, which could easily drift off frequency by 3-4 kHz. Since stations were assigned frequencies only 10 kHz apart, interference between adjacent stations due to frequency drift was common. In 1925 Westinghouse tried out a crystal oscillator in its flagship station KDKA, and by 1926 quartz crystals were used to control the frequency of many broadcasting stations and were popular with amateur radio operators. In 1928, Warren Marrison (of Bell Telephone Laboratories) developed the first quartz crystal clock... Using what are now considered primitive methods, about 100,000 crystal units were produced in the United States during 1939. Through World War II crystals were made from natural quartz crystal, virtually all from Brazil. Shortages of crystals during the war caused by the demand for accurate frequency control of military and naval radios and radars spurred postwar research into culturing synthetic quartz, and by 1950 a hydrothermal process for growing quartz crystals on a commercial scale was developed at Bell Laboratories. By the 1970s virtually all crystals used in electronics were synthetic...

1920 Film: How the Telephone Talks (A Silent Film)
 
07:01
A film from 1920 that explained the "modern" telephone. The concepts are still relevant to today's modern versions, including the cell phone, which is both radio and telephone. This film was provided by the Prelinger Archives collection ( http://prelinger.com ) under the Creative Commons License (Public Domain) ( http://g.nw7us.us/1993PUN ). I added music, and conditioned the film for High Definition (HD) playback. Thank you for watching, sharing, commenting, and subscribing. -- Tomas / NW7US ( http://nw7us.us ) From Wikipedia, the free encyclopedia that anyone can edit ( http://g.nw7us.us/19943eq ): A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are not in the same vicinity of each other to be heard directly.

The telephone network, consisting of a worldwide net of telephone lines, fiber optic cables, microwave transmission, cellular networks, communications satellites, and undersea telephone cables connected by switching centers, allows any telephone in the world to communicate with any other. Each telephone line has an identifying number called its telephone number. To initiate a telephone call the user enters the other telephone's number into a numeric keypad on the phone. Although originally designed for simple voice communications, most modern telephones have many additional capabilities. They may be able to record spoken messages, send and receive text messages, take and display photographs or video, play music, and surf the Internet. A current trend is phones that integrate all mobile communication and computing needs; these are called smartphones.

4 Unidentified Sounds | What the Stuff?!
 
04:48
Have you ever heard the Taos Hum, or detected a signal from space? What the heck is that radio tower in Russia doing? Learn more about the world’s most mysterious noises. 10 Unidentified Sounds: http://science.howstuffworks.com/science-vs-myth/unexplained-phenomena/10-unidentified-sounds.htm Music: "I Don't See the Branches, I See the Leaves" by Chris Zabriskie https://freemusicarchive.org/music/Chris_Zabriskie/Direct_to_Video_1014/03_-_I_Dont_See_the_Branches_I_See_the_Leaves * Have you ever heard a weird, unexplainable sound? Like a bump in the night, a voice from an empty room and stuff like that? If so, you’re not alone. In fact, there are a few strange noises even the experts can’t explain. * Wow! Signal – In 1997 at Ohio State University’s Big Ear radio telescope, a volunteer named Jerry Ehman noticed an extremely powerful signal from space 30 times louder than the typical ambient noise of the cosmos – and very close to 1,420 megahertz, the frequency of hydrogen. Only lasted 72 seconds. Despite more than 100 subsequent studies of the same region, no one’s found anything like it again. Was it a natural anomaly? Some sort of alien signal? We have no idea. *The Upsweep Earth’s oceans are pretty mysterious today, so it’s no wonder that they’d also be a source of bizarre noises, from volcanic tremors to humpback whales. Scientists at the National Oceanic and Atmospheric Administration use a network of hydrophones to detect sounds across the maritime world. We can explain most of these noises – or at least make a pretty compelling guess. But there’s one thing we can’t explain – at least, not yet: The Upsweep, first detected in 1991. It’s a set of narrow-band upsweeping sounds, each lasting several seconds, powerful enough to be recorded throughout the Pacific. The Upsweep seems to be seasonal, peaking in spring and fall. Why? We have no idea. *UVB-76 In the 1980s, a radio tower north of Moscow transmitted a series of beeps, switching to buzzing sounds in 1992. Each buzz only lasted about a second, occurring about 21-34 times a minute. Every few weeks, a male voice would interrupt the signal to recite a string of numbers and words. The tones, amplitudes, and pitch of the buzzing shifted, and the intervals also changed. In 2010 the station briefly stopped sending out signals twice. At the end of August, after the second break in the signal, everything changed. The station broadcasts thuds and shuffling sounds, along with snippets of music like “Dance of the Little Swans” or “Swan Lake”. Though there’s no public proof, most people assume this is a spy operation, transmitting messages to secret agents. *The Max Headroom Incident This one is unexplained, in that nobody knows who did it or how they did it. On Nov. 22, 1989, a hacker took over the frequencies of two Chicago-area TV stations. The first time, during a CBS newscast, technicians shut it down in 30 seconds. The second attack, against a public TV station, lasted well over a minute. The PBS drama cut out and a man in a Max Headroom mask appeared, broadcasting a cryptic audio message, with lines like "your love is fading" and a hummed snippet of the theme song from the cartoon "Clutch Cargo"  For more than two decades people have tried to figure out who did this. You can find some compelling theories, but for now, this remains the world’s most mysterious Max Headroom impersonator. *The Taos Hum Taos, New Mexico isn't the only place where a bizarre ambient hum is heard, but it's probably the most famous spot for the mysterious droning. The Taos Hum has been described as a sound similar to the low rumble of a diesel truck's engine People who noticed it are bothered to varying degrees, with some experiencing a mild feeling of irritation, while others report sleep disturbances, dizziness and nosebleeds. Scientists think it may be caused by low frequency waves that originate in the atmosphere or else by vibrations from deep within Earth. Or perhaps some people are extraordinarily sensitive to certain electromagnetic frequencies, and that the hum is caused by devices such as cell phones. Conspiracy theorists suggest that it's caused by some sort of secret military communications system used to contact submarines, or a clandestine weapons testing program. But again, nobody really knows for sure  * And you know what that sound means – our time is up. Thanks so much for watching. Can you think of an explanation for these sounds? Let us know in the comments, and if you’d like to know more, check out our article “10 Unidentified Sounds That Scientists Are Seriously Looking Into.”

Grebe (1895-October 24, 1935) was a pioneer in the radio broadcasting field... By age 15, he became a licensed commercial operator, and went to work as a ship's radio operator. After three years onboard (during which time he traveled as far as India) he returned to Long Island, where the first commercial station on the island was being built at Sayville. He got a job as an operator there. Later, because there was currently a radio craze, some friends had him make receivers for them. After making a few sets, he decided to go into commercial production. In 1914 he issued his first catalog, and set up a factory in Richmond Hill on the same property where his home was located, which soon became able to produce all the components needed to assemble a radio, and which contained research laboratories as well. By 1922 he tore down his home to build a larger factory on the site. To stimulate public interest, he set up several radio stations: one (WAHG) was identified with his own initials; another (WBOQ) had call letters standing for Borough of Queens. (His WAHG is, through several call letter changes, now WCBS, still a major radio station in New York City.) He set up a broadcasting company called the "Atlantic Broadcasting Corporation" (changing WAHG to WABC on November 1, 1926) which operated his stations until he sold them to CBS in January 1929. His manufacturing company, A. H. Grebe and Co. Inc., was renamed Grebe Radio and Television Corporation and moved from Richmond Hill to Manhattan in 1933. In 1935 he underwent a stomach operation at Post-Graduate Hospital in Manhattan. He became ill after the operation and died after 10 days. http://www.radioblvd.com/Grebe%20Synchrophase.htm For decades, vintage radio collectors have rated the Grebe Synchrophase MU-1 as one of the best, if not "the best," Battery-operated TRF-Neutrodyne radio receiver, with performance that is matched with timeless styling. However, anyone that has taken a close look at more than a few Grebe Synchrophase MU-1 receivers has surely noted that there are some significant differences between the various MU-1 receivers produced. During the mid-1920s, RADIO was evolving so fast Grebe had to continually re-engineer the Synchrophase to keep it up to date... https://en.wikipedia.org/wiki/Tuned_radio_frequency_receiver A tuned radio frequency receiver (or TRF receiver) is a type of radio receiver that is composed of one or more tuned radio frequency (RF) amplifier stages followed by a detector (demodulator) circuit to extract the audio signal and usually an audio frequency amplifier. This type of receiver was popular in the 1920s. Early examples could be tedious to operate because when tuning in a station each stage had to be individually adjusted to the station's frequency, but later models had ganged tuning, the tuning mechanisms of all stages being linked together, and operated by just one control knob. By the mid 1930s, it was replaced by the superheterodyne receiver invented by Edwin Armstrong... https://en.wikipedia.org/wiki/Neutrodyne The Neutrodyne was a particular type of tuned radio frequency (TRF) radio receiver, in which the instability-causing inter-electrode capacitance of the triode RF tubes is cancelled out or "neutralized". to prevent parasitic oscillations which caused "squealing" or "howling" noises in the speakers of early radio sets. In most designs, a small extra winding on each of the RF amplifiers' tuned anode coils was used to generate a small antiphase signal, which could be adjusted by special variable trim capacitors to cancel out the stray signal coupled to the grid via plate-to-grid capacitance...

How to Make AM Radio Transmitter

How to make an AM radio transmitter for use with a crystal radio or a normal AM radio. This simple circuit uses an oscillator chip and a transformer to take input from a sound source and turn it into radio waves, transmitted using an antenna. I test it with a CD player as the sound source but it may also work with an iPod or iPhone, though it may need some amplification for that. WARNING: Do not transmit more than 1 or 2 meters/yards otherwise you'll interfere with other radios. In many countries it is illegal to transmit without a license.

How a Crystal Radio Works
 
12:58
Full details of how a crystal radio works, right down to the electron level. We start with a demonstration of all the parts in action, showing how the radio waves interact with the antenna and antenna coil to produce a fluctuating magnetic field, which induces electron flow in the tuning coil, which works with the tuning capacitor, which is followed by the diode and crystal earpiece. We talk about why a leaky germanium diode is needed with this particular circuit or how a bypass resistor can be used instead. That's followed by how the tuning is done using a tuning coil in parallel with a tuning capacitor, which together are tuned to a resonant frequency the same as the radio frequency by adjusting the coil's inductance and the capacitor's capacitance. Then we show how a radio wave is formed from a microphone's audio wave using amplitude modulation (AM). This then shows how the diode is necessary for converting the radio wave back to an audio wave for use by the earpiece or speaker. Next we discuss selectivity versus sensitivity and why a separate antenna coil is used. An finally we show a few other crystal radio circuits.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://en.wikipedia.org/wiki/Telephony Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ In telecommunications, telephony encompasses the general use of equipment to provide communication over distances, specifically by connecting telephones to each other. The technology is associated with the electronic transmission of voice, fax, or other information between distant parties using systems historically associated with the telephone, a hand-held device containing both a speaker or transmitter and a receiver. It is commonly referred to as the construction or operation of telephones or telephonic systems and as a system of telecommunications in which telephonic equipment is employed in the transmission of speech or other sound between points, with or without the use of wires.. To break the term down into further detail, telephony is the science of translating sound into electrical signals, transmitting them, and then converting them back to sound; that is, the science of telephones. The term is used frequently to refer to computer hardware and software that performs functions traditionally performed by telephone equipment. For example, telephony software can combine with your modem to turn your computer into a sophisticated answering service. A popular example of this type of telephony software is voice mail... Brief overview Telephones were originally connected directly together in pairs. Each user would have a separate telephone wired to various places he might wish to reach. This became inconvenient when people wanted to communicate with many other people using telephones, so the telephone exchange was invented. Each telephone could then be connected to other local ones, thus inventing the local loop and the telephone call. Soon, nearby exchanges were connected by trunk lines, and eventually distant ones were as well. In modern times, most telephones are plugged into telephone jacks. The jacks are connected by inside wiring to a drop wire which connects the building to a cable. Cables usually bring a large number of drop wires from all over a district access network to one wire center or telephone exchange. When the user of a telephone wants to make a telephone call, equipment at the exchange examines the dialed telephone number and connects that telephone line to another in the same wire center, or to a trunk to a distant exchange. Most of the exchanges in the world are connected to each other, forming the public switched telephone network (PSTN). By the end of the 20th century almost all were stored program control exchanges. After the middle of the 20th century, fax and data became important secondary users of the network created to carry voices, and late in the century, parts of the network were upgraded with ISDN and DSL to improve handling of such traffic. Today, telephony has been digitized and has merged into digital telephony,.. Another important concept that has been merged into telephony is computer telephony integration, which enables computers to know about and control phone functions such as making and receiving voice, fax, and data calls with telephone directory services and caller identification...

Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://en.wikipedia.org/wiki/Telephone Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are not in the same vicinity of each other to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user. The word telephone has been adapted into the vocabulary of many languages. It is derived from the Greek: τῆλε, tēle, "far" and φωνή, phōnē, "voice", together meaning "distant voice". First patented in 1876 by Alexander Graham Bell and further developed by many others, the telephone was the first device in history that enabled people to talk directly with each other across large distances. Telephones rapidly became indispensable to businesses, government, and households, and are today some of the most widely used small appliances. The essential elements of a telephone are a microphone (transmitter) to speak into and an earphone (receiver) which reproduces the voice of the distant person. In addition, most telephones contain a ringer which produces a sound to announce an incoming telephone call, and a dial used to enter a telephone number when initiating a call to another telephone. Until approximately the 1970s most telephones used a rotary dial, which was superseded by the modern DTMF push-button dial, first introduced by AT&T in 1963. The receiver and transmitter are usually built into a handset which is held up to the ear and mouth during conversation. The dial may be located either on the handset, or on a base unit to which the handset is connected. The transmitter converts the sound waves to electrical signals which are sent through the telephone network to the receiving phone. The receiving telephone converts the signals into audible sound in the receiver, or sometimes a loudspeaker. Telephones are a duplex communications medium, meaning they allow the people on both ends to talk simultaneously. A landline telephone is connected by a pair of wires to the telephone network, while a mobile phone, such as a cellular phone, is portable and communicates with the telephone network by radio transmissions. The public switched telephone network, consisting of telephone lines, fiberoptic cables, microwave transmission, cellular networks, communications satellites, and undersea telephone cables connected by switching centers, allows telephones around the world to communicate with each other. Each telephone line has an identifying telephone number. To initiate a telephone call the user enters the other telephone's number into a numeric keypad on the phone. Graphic symbols used to designate telephone service or phone-related information in print, signage, and other media include ℡ (U+2121), ☎ (U+260E), ☏ (U+260F), ✆ (U+2706), and ⌕ (U+2315). Although originally designed for simple voice communications, most modern telephones have many additional capabilities. They may be able to record spoken messages, send and receive text messages, take and display photographs or video, play music, and surf the Internet. A current trend is phones that integrate all mobile communication and computing needs; these are called smartphones...

USB to VGA Adapter - Transmit Radio Signals! (FL2000 / FL2K) [News]
 
04:18
In this video I talk about the latest discovery by the Osmocom team, who have made it possible to transmit radio signals with USB to VGA adapters! The USB 3.0 to (Analog) VGA adapter is able to transmit radio signals because of the DAC (Digital to Analog Converter) chip, known specifically as Fresh Logic 2000, or FL2000/FL2K in short. These adapters can be bought for as low as 5$, so they are definitely worth trying out for this type of hack. From my preliminary testing, results have been mixed but it did work with WBFM (Wideband FM) and also a "Dummy GSM signal". For the latter, keep in mind that you still need a full-duplex SDR to enable clients to authenticate to your own GSM network. This device should also be able to transmit GPS. I have not been able to get mine to transmit a consistent GPS signal yet, but that would make GPS spoofing very cheap. Keep in mind that the generated signal without any modifications to the adapter is not very strong, at least not in my case. However, always be careful when transmitting any type of radio signal and check applicable local laws if you want to be on the safe side. It's important to note that not all USB to VGA adapters are compatible with this type of hack. If they advertise higher resolution than 1920 x 1080 at 60Hz, then they're most likely not using this chip. It also needs to be USB, preferably USB 3.0, as you will be able to achieve much greater "million samples per second" (i.e. ~130MS/s in my case) than USB 2.0 (~15MS/s i think).

Why was the radio invented? Blurtitencyclopedia articles about how Fun kids uk's children's station. Marconi [ 31 may 2007 radio has transformed society three times, not to mention giving birth the entire field of electronics. Reference an italian named guglielmo marconi invented the radio in 1895 as a means of transmitting information using wireless waves. The idea of wireless communication predates the discovery 'radio' with experiments in many people were involved invention radio as we know it today. Rather, it received buzzing sounds created by a spark gap transmitter sending signal using morse code who's in charge of radio waves? Roll forward to 1920 and marconi was inventing way signals over those why can't i hear. Perhaps no invention of modern times the question who invented radio comes with a certain amount controversy. 225 in 1894, he began experimenting with radio waves as a student at the livorno technical answer (1 of 8) the radio was invented to help with communications and it also was a means of entertainment to the ones who invented them, the radio helped marconi's radio did not receive voice or music. Why do people believe that marconi or tesla invented the radio radio, not marconi!. Radio started as wireless telegraphy. The history of the radio personal. In 1893 the inventor nikolai tesla demonstrated a wireless radio in st. Main article invention of radio. Italian inventor and engineer guglielmo marconi (1874 1937) developed, demonstrated in 1909 he shared the nobel prize physics for his radio work. Experimental work on the connection between electricity and magnetism began around italian inventor radio pioneer guglielmo marconi in front of a telegraph laboratory but more than 100 years later, ask any two people who invented you're likely to why did thomas edison electrocute an elephant? . He developed the technology 26 mar 2017 an outline of development radio owes its guglielmo marconi, italian inventor, proved feasibility communication. It's easy to compress complex histories into one sentence help third and that is more or less why he never did get credit for inventing radio despite the fact patent it in us same year marconi got his first british.

All you need is a pair of awesome wireless headphones, and thankfully we've rounded up the best 5 right here. Headphones (or head-phones in the early days of telephony and radio) are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earspeakers, earphones[1] or, colloquially, cans.[2] Circumaural and supra-aural headphones use a band over the top of the head to hold the speakers in place. The other type, known as earbuds or earpieces[1] consist of individual units that plug into the user's ear canal. In the context of telecommunication, a headset is a combination of headphone and microphone. Headphones connect to a signal source such as an audio amplifier, radio, CD player, portable media player, mobile phone, video game console, or electronic musical instrument, either directly using a cord, or using wireless technology such as Bluetooth, DECT or FM radio. The first headphones were developed in the late 19th century for use by telephone operators, to keep their hands free. Initially the audio quality was mediocre and a step forward was the invention of high fidelity headphones.[3] Headphones are made in a range of different audio reproduction quality capabilities. Headsets designed for telephone use typically cannot reproduce sound with the high fidelity of expensive units designed for music listening by audiophiles. Headphones that use cables typically have either a 1/4 inch (6.35mm) or 1/8 inch (3.5mm) phone jack for plugging the headphones into the audio source. Some stereo earbuds are wireless, using Bluetooth connectivity to transmit the audio signal by radio waves from source devices like cellphones and digital players.[4] Due to the spread of wireless devices in recent years headphones are increasingly used by people in public places such as sidewalks, grocery stores, and public transit. Headphones are also used by people in various professional contexts, such as audio engineers mixing sound for live concerts or sound recordings and DJs, who use headphones to cue up the next song without the audience hearing, aircraft pilots and call center employees. The latter two types of employees use headphones with an integrated microphone. Lets connect: BLOG: https://stayhealthygetweal.wixsite.co...

CW Practice Key - MFJ Code Oscillator https://amzn.to/2VP4o75 Sample text files http://appropriatesoftware.com/NE1OB/RandomQSOs/ See "Text" on the right side. http://www.smrcc.org.uk/Morse/morse.htm CW Morse Practice Motivation Best Phone App My tips and tricks for learning CW / Morse Code for ham amateur radio. There are many skills in this tutorial that I talk about in this video as well. It takes practice to get good and sending code on the radio. CW software is going to help you get there also. You'll need a good CW Iambic Paddle as well. Continuous wave has many benefits. You'll want to reap these benefits when I teach you CW keying. Learning Morse Code is not that hard. Now simply called "CW", radio communication by Morse code was the only way to communicate for the first decade or more of Amateur Radio. Radiotelegraphy, the proper name, descends from landline (wired) telegraphy of the 19th century, and retains some of the old culture, including a rich set of abbreviations and procedures. Morse sent by spark gap transmitter was the first wireless communication mode. These "damped waves" were very broad and inefficient for communication. They were soon replaced by "Continuous Wave" (CW) transmission, using vacuum tube oscillators that were capable of a very pure note. Today, modern Amateur Radio transceivers use solid state components and microprocessors to support a variety of communication modes including CW, voice, image and many digital data modes. A continuous wave or continuous waveform (CW) is an electromagnetic wave of constant amplitude and frequency; a sine wave. In mathematical analysis, it is considered to be of infinite duration. Continuous wave is also the name given to an early method of radio transmission, in which a sinusoidal carrier wave is switched on and off. Information is carried in the varying duration of the on and off periods of the signal, for example by Morse code in early radio. In early wireless telegraphy radio transmission, CW waves were also known as "undamped waves", to distinguish this method from damped wave transmission as effected by early spark gap style transmitters. Very early radio transmitters used a spark gap to produce radio-frequency oscillations in the transmitting antenna. The signals produced by these spark-gap transmitters consisted of strings of brief pulses of sinusoidal radio frequency oscillations which died out rapidly to zero, called damped waves. The disadvantage of damped waves was that their energy was spread over an extremely wide band of frequencies; they had wide bandwidth. As a result they produced electromagnetic interference (RFI) that spread over the transmissions of stations at other frequencies. This motivated efforts to produce radio frequency oscillations that decayed more slowly; had less damping. There is an inverse relation between the rate of decay (the time constant) of a damped wave and its bandwidth; the longer the damped waves take to decay toward zero, the narrower the frequency band the radio signal occupies, so the less it interferes with other transmissions. As more transmitters began crowding the radio spectrum, reducing the frequency spacing between transmissions, government regulations began to limit the maximum damping or "decrement" a radio transmitter could have. Manufacturers produced spark transmitters which generated long "ringing" waves with minimal damping. It was realized that the ideal radio wave for radiotelegraphic communication would be a sine wave with zero damping, a continuous wave. An unbroken continuous sine wave theoretically has no bandwidth; all its energy is concentrated at a single frequency, so it doesn't interfere with transmissions on other frequencies. Continuous waves could not be produced with an electric spark, but were achieved with the vacuum tube electronic oscillator, invented around 1913 by Edwin Armstrong and Alexander Meissner. In order to transmit information, the continuous wave must be turned off and on with a telegraph key to produce the different length pulses, "dots" and "dashes", that spell out text messages in Morse code, so a "continuous wave" radiotelegraphy signal consists of pulses of sine waves with a constant amplitude interspersed with gaps of no signal. Damped wave spark transmitters were replaced by continuous wave vacuum tube transmitters around 1920, and damped wave transmissions were finally outlawed in 1934.

Garmin GPS Review
 
00:51
Garmin GPS Review http://tubecheckout.com/GarminGPS GPS satellites transmit two low power radio signals, designated L1 and L2. Civilian GPS uses the L1 frequency of 1575.42 MHz in the UHF band. The signals travel by line of sight, meaning they will pass through clouds, glass and plastic but will not go through most solid objects such as buildings and mountains. A GPS signal contains three different bits of information - a pseudorandom code, ephemeris data and almanac data. The pseudorandom code is simply an I.D. code that identifies which satellite is transmitting information. You can view this number on your Garmin GPS unit's satellite page, as it identifies which satellites it's receiving. Garmin GPS http://youtu.be/QbeDR25qtRA
