How Radio Waves Are Produced

UNLOCKING THE MYSTERIES BEHIND RADIO WAVES. Electric current creates magnetic field, oscillating electric current creates oscillating magnetic field and not "electromagnetic wave" as current belief. Electron has a standing- electric field and magnetic field at right angle (watch video structure of electron). The flow of electrons in a conductor is essentially caused by the attraction between the electric fields of mobile electrons and "fixed" positive charges in the conductor. Oscillation of electrons in a conductor is caused by the alternation of electric polarity in the conductor. Because of electric field and magnetic field of an electron is at right angle, when oscillates the electric field of the electron will be parallel to the oscillation and magnetic field will be perpendicular to the oscillation.This oscillation of the electron creates transverse wave on its magnetic line and the oscillating magnetic line is radiated to space. http://www.amazon.com/author/atom http://www.facebook.com/novaphysica https://www.youtube.com/user/atommodel

The Alien Signals Mystery Might Have Been Solved
 
11:20
What are those scary metallic sounds from space? Do aliens send signals to us? Scientists may finally have been discovered the source of the strange sound from space. We’ve learned a lot about the universe, but there’s still so much we don’t know. One mystery in particular has been tormenting the minds of scientists for years. In 2007, researchers caught some weird radio signals coming from a place billions of light-years away.These signals weren’t the first radio signals scientists ever heard coming from deep space. They’re something known as fast radio bursts (FRBs) and can be described as short pulses of radio flashes arriving from the galactic outskirts of the universe. These bursts, whose exact sources are completely unknown to us, last a tiny fraction of a second and usually appear alone. Researchers at the Harvard-Smithsonian Center for Astrophysics suppose that the source of these FRBs could be a gigantic transmitter twice the size of Earth powered by sunlight. The second theory states that strong extragalactic beeps seem to be arriving from a massive black hole or an unprecedentedly powerful neutron star located more than 3 billion light-years from our planet in a potent interstellar nebula. Jason Hessels, associate professor of the University of Amsterdam, and his team of researchers believe that the source of the bursts could be a rotating neutron star whose home is a place with a harsh magnetic environment, for example, a black hole that’s sucking in dust and gas and, therefore, still growing. TIMESTAMPS Signals from space in 2007 1:06 The source of the mysterious “alien signals”: Theory 1: a gigantic transmitter 2:26 Why FRB 121102 is unique 4:45 Theory 2: black hole 5:30 Theory 3: neutron star 7:00 How many radio bursts occur 8:59 Bonus: The Sun’s Influence On Our Planet 10:20 Music: https://www.youtube.com/audiolibrary/music SUMMARY -In 2007, researchers caught some weird radio signals coming from a place billions of light-years away, and these strange sounds definitely got their attention. -Researchers at the Harvard-Smithsonian Center for Astrophysics suppose that the source of these FRBs could be a gigantic transmitter twice the size of Earth powered by sunlight. -Scientists have already observed as many as 200 high-energy radio pulses emitted by FRB 121102 in just 5 years of study which makes it unique. -Astronomers believe these unusually strong extragalactic beeps seem to be arriving from a massive black hole or an unprecedentedly powerful neutron star located more than 3 billion light-years from our planet in a potent interstellar nebula. -The source of the bursts lies in a star-forming area of a dwarf galaxy, and the electromagnetic waves that create the bursts follow an absolutely unique pattern. It means that they originate from a place with a magnetic field that’s incredibly strong. Such fields can be found near neutron stars or massive black holes like the ones in the centers of galaxies. -The astronomers from the Harvard-Smithsonian Center for Astrophysics have been trying to calculate the number of potential FRBs occurring in the part of the universe we can observe. The results are quite shocking: at least one fast radio burst goes off in some place every second. -According to scientists, in the next 100 years the Sun’s activity will lead to a significant temperature change on Earth, decreasing it by half a degree.

How to Make AM Radio Transmitter
 
08:43
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. For how to make the homemade crystal radio, watch "How to Make/Build a Crystal Radio": http://youtu.be/VqdcU9ULAlA For how to make the crystal earpiece watch "Make Crystal Earphone/Earpiece for Crystal Radio - Homemade": http://youtu.be/OVapqz4yBCY For how to make a lifter or ionocraft, watch "How to Make a Lifter": http://youtu.be/vzZy1Aqleno My webpage about how to make a simple AM radio transmitter: http://rimstar.org/science_electronics_projects/make_simple_am_radio_transmitter.htm Where to get a 1 megahertz oscillator chip and an audio transformer: https://www.scitoyscatalog.com/category/R.html Follow behind-the-scenes on: Twitter https://twitter.com/#!/RimStarz Google+ https://plus.google.com/116395125136223897621 http://rimstar.org Music used for background: The Path of the Goblin King Kevin MacLeod (incompetech.com) Licensed under Creative Commons: By Attribution 3.0 http://creativecommons.org/licenses/by/3.0/ ISRC: USUAN1100873

NASA RECEIVED SOS CALL FROM ANOTHER GALAXY?
 
06:30
NASA detected, intercepted, and decoded a mathematically-based distress signal from a purportedly doomed planetoid outside our own galaxy. The signal was detected in January of 1998 but, however and as it might be expected, it took many years to properly decode the message. NASA experts claim to have intercepted an intergalactic distress call from an alien civilization that had already peaked and was actually dying when saber-tooth tigers still roamed the earth. The 80,000-year-old SOS was received and digitally recorded in late January 1998. But only in 2011 have radio astronomers and language experts found the key to the complex mathematics-based language that enabled them to translate the 'frantic plea for help'. The world press has been suspiciously silent about the startling message, though lengthy scientific reports are scheduled for publication in two professional journals, Radio Astronomy and Universe. According to a highly placed NASA source in Houston, Texas, noted Russian superior officer Gen. in ex-Soviet Union’s army, Viktor Kulikov was leading a United Nations research team from a state-operated observatory 50 miles northwest of Moscow. http://en.wikipedia.org/wiki/Viktor_Kulikov Gen. Victor Kulikov told Universe that the signal emanated from a point beyond the galaxy nearest to our own, Andromeda, and was sent by beings that had apparently achieved a civilization no more advanced than our own here on Earth. “The simple fact that we received and decoded the message proves beyond any doubt that their knowledge and technology were, at the very best, within our reach.” Dr. Kulikov explained. “And while there are years of study ahead of us, I can say with certainty that the death of their civilization was not the result of some cosmic catastrophe. It was the result of the civilization turning on itself, possibly with devastating nuclear weaponry.” Dr Kulikov flatly refused to provide either of the magazines with a transcript of the message, but he did say it began with the plea, “Help us,” and went on to give data pinpointing the exact position of the doomed planet. There was a quite lucid account of apocalyptic devastation, hellish explosions, widespread death and terminal illnesses,” he said. “A Shower of meteors? Perhaps. But what stikes me, and this is just a feeling, is an underlying acceptance of guilt. It’s as if the senders of the message are acknowledging blame for what happened.” "Whatever it was, they apparently had no means to evacuate the remaining population. Interplanetary space travel was available to them, but only on a very limited level. The message makes it very clear that they were trapped on their world,” said Dr. Kulikov. The article was written by two journals. NASA simply managed to not get much publicity. At that time the newspapers wrote very little about this issue. When after thirteen years managed to decrypt the message fails to hide from the media.

How to Build a Radio Telescope (See Satellites 35,000km Away!)
 
13:49
Over the last 2 months me and my friend Artem (you met him in the last video) built our first radio telescope. It was built mostly out of off the shelf components, like a satellite dish and Ku band LNB, as well as some parts we 3d printed. When all was said and done we had a system that could not only take images of the sky in radip frequencies (in this case 10-12ghz), but could also be used to track satellites. With it, we were able to see the ring of satellites in geosynchronous orbit, over 35,000km away, This is only the first of what I suspect will be many more telescopes like this. Next time we'll be building ones that are far larger and can see things like the hydrogen lines so we can image the milky way.

Electromagnetic Spectrum: Radio Waves
 
03:58
http://www.facebook.com/ScienceReason ... [email protected]: EMS Electromagnetic Spectrum (Episode 2) - Radio Waves The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- MEASURING THE ELECTROMAGNETIC SPECTRUM The electromagnetic (EM) spectrum is just a name that scientists give a bunch of types of radiation when they want to talk about them as a group. Radiation is energy that travels and spreads out as it goes - visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays. Hotter, more energetic objects and events create higher energy radiation than cool objects. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays. • http://imagine.gsfc.nasa.gov/docs/science/know_l1/emspectrum.html --- RADIO WAVES Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Like all other electromagnetic waves, they travel at the speed of light. Naturally-occurring radio waves are made by lightning, or by astronomical objects. Artificially-generated radio waves are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, satellite communication, computer networks and innumerable other applications. Different frequencies of radio waves have different propagation characteristics in the Earth's atmosphere; long waves may cover a part of the Earth very consistently, shorter waves can reflect off the ionosphere and travel around the world, and much shorter wavelengths bend or reflect very little and travel on a line of sight. Discovery and utilization: Radio waves were first predicted by mathematical work done in 1865 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations, that described light waves and radio waves as waves of electromagnetism that travel in space. In 1887, Heinrich Hertz demonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory. Many inventions followed, making practical the use of radio waves to transfer information through space. Propagation: The study of electromagnetic phenomena such as reflection, refraction, polarization, diffraction and absorption is of critical importance in the study of how radio waves move in free space and over the surface of the Earth. Different frequencies experience different combinations of these phenomena in the Earth's atmosphere, making certain radio bands more useful for specific purposes than others. Radio communication: In order to receive radio signals, for instance from AM/FM radio stations, a radio antenna must be used. However, since the antenna will pick up thousands of radio signals at a time, a radio tuner is necessary to tune in to a particular frequency (or frequency range). This is typically done via a resonator (in its simplest form, a circuit with a capacitor and an inductor). The resonator is configured to resonate at a particular frequency (or frequency band), thus amplifying sine waves at that radio frequency, while ignoring other sine waves. Usually, either the inductor or the capacitor of the resonator is adjustable, allowing the user to change the frequency at which it resonates. In medicine: Radio frequency (RF) energy has been used in medical treatments for over 75 years generally for minimally invasive surgeries and coagulation, including the treatment of sleep apnea. • http://en.wikipedia.org/wiki/Radio_waves .

VOR VHF Omni directional Radio Range -- PILOT TRAINING
 
11:31
VHF Omni Directional Radio Range (VOR) is a type of short-range radio navigation system for aircraft, enabling aircraft with a receiving unit to determine their position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons. It uses frequencies in the very high frequency (VHF) band from 108 to 117.95 MHz. Developed in the United States beginning in 1937 and deployed by 1946, VOR is the standard air navigational system in the world A VOR ground station sends out an omnidirectional master signal, and a highly directional second signal is propagated by a phased antenna array and rotates clockwise in space 30 times a second. This signal is timed so that its phase (compared to the master) varies as the secondary signal rotates, and this phase difference is the same as the angular direction of the 'spinning' signal, (so that when the signal is being sent 90 degrees clockwise from north, the signal is 90 degrees out of phase with the master). By comparing the phase of the secondary signal with the master, the angle (bearing) to the aircraft from the station can be determined. This bearing is then displayed in the cockpit of the aircraft, and can be used to take a fix as in earlier radio direction finding (RDF) systems. This line of position is called the "radial" from the VOR. The intersection of two radials from different VOR stations on a chart gives the position of the aircraft. VOR stations are fairly short range: the signals are useful for up to 200 miles. VOR stations broadcast a VHF radio composite signal including the navigation signal, station's identifier and voice, if so equipped. The navigation signal allows the airborne receiving equipment to determine a bearing from the station to the aircraft (direction from the VOR station in relation to Magnetic North). The station's identifier is typically a two- or three-letter string in Morse code. The voice signal, if used, is usually the station name, in-flight recorded advisories, or live flight service broadcasts. At some locations, this voice signal is a continuous recorded broadcast of Hazardous Inflight Weather Advisory Service or HIWAS.

What is RFID?  How RFID works?  RFID Explained in Detail
 
10:10
In this video, RFID (Radio Frequency Identification) Technolgy has been explained. So, in this video, what is RFID, what is inside this RFID system, how RFID works, and application of RFID have been explained. What is RFID? RFID is technology which works on radio frequency and it is used for the auto-identification for the different object. The RFID system mainly consists of two parts. 1) RFID Reader or Interrogator 2) RFID Tags In this RFID system, this RFID reader continuously sends radio waves of a particular frequency. If the object, on which this RFID tag is attached is within the range of this radio waves then it sends the feedback back to this RFID reader. And based on this feedback, RFID reader identifies the object. RFID tags: Now, three different kinds of RFID tags are commercially available. 1) Passive tags 2) Active tags 3) Semi-passive tags These passive tags do not have any power supply. They used to get their power from the incoming radio waves from the Readers. While active tags have a power source for their internal circuitries. And for sending the response to the reader also, it uses its own power supply. In the case of semi-passive tags, they have a power supply for internal circuitries, but for sending the response it relies on the radio waves received from the Reader. Operating Frequency: This RFID system is mainly operated in three frequency bands. 1) LF: Low-Frequency band 2) HF: High-Frequency band 3) UHF: Ultra High-Frequency band The exact frequency of operation varies from country to country. Operating Principles: Most of the RFID systems operate on any of this two principles. 1) Load Modulation 2) Backscattered Modulations Applications of RFID: 1. Institutions: Library, Hospitals, Schools, and Colleges 2. Transportation and Logistics 3. Access Control 4. Sports 5. Animal Tracking Timestamps for the different topics in the video is given below: 0:40 What is RFID? 1:56 What is inside this RFID chip? 4:42 Operating Frequencies for the RFID Systems 5:27 Working Principle of RFID Systems This video will be helpful to everyone in understanding the concept of RFID Technology.

Titanic Text Messges - A Streaming Log of Distress Transmissions
 
53:13
[***UPDATE*** The audio from 00:53 to 01:40 is incorrect. I accidentally added the wrong sound file to this section of the video. My apologies!] I've taken all the Morse code communications I could find from the night of the Titanic disaster and turned it into streaming text. It's painfully slow by today's standards of communications as it presents at about the speed the transmissions were made that night. I've removed the "dead air" time cutting the total time from about two hours to one. Morse code abbreviations have been included in the audio but the text is in English, for example the ship's ID code "MGY" will be heard but "TITANIC" will be read. "OM" will be heard but "OLD MAN" (meaning "buddy" or "friend") will be in the text. I've left the code "CQD" as it's very prominent and important. This was the common international distress signal at the time and stood for "ATTENTION ALL STATIONS" (CQ) "DISTRESS" (D). Titanic was not the first to transmit an SOS but she used it also. They primarily used CQD because that was the most recognized distress signal of the time. The log starts as the Titanic is transmitting personal telegrams for customers which are interrupted by the distress signal. It continues until the last message is transmitted. I've tried to make it as historically accurate as possible but I'm not a historian, just a Joe.

How does an ILS work? One of the most ask question regarding how an airplane flies towards the runway without any visual aids. So the Instrument landing system is a ground based radio navigation system giving pilots a lateral and vertical guidance towards the runway as they are in approach in IMC (Instrument Metrological Conditions). To fly an ILS approach, the aircraft has to be fitted with an adequate ILS receiver to display and converted the picked up signals on the cockpit instruments. Besides that, you need the necessary ILS approach chart with important data like ILS frequency and identifer code, ILS inbound course and glideslope angle, given minimum descent altitudes or heights depending on the ILS category, and last but not least the go arround procedure. The so called localizer is an antenna array normally located beyond the end of the runway and generally is built up of several pairs of directional antennas. They send out radio signals in the horizontal axis of the runway.(This is very often mistaken, as many airports have to Localizer antennas, for either direction of the runway. So this plane right here is not flying in regards to this antenna right here, but to the antenna at the far end of the runway it´s landing on) Also important to know, at the same time the localizer transmits the so called ILS facility identification code. What is that good for? Because the frequency range for the ILS is fairly small, you could pick up the wrong ILS frequency of a nearby airport. Therefor each ILS sends out it´s own morse code, for example the ILS identifaction code for John F.Kennedy airport runway 04Right is IJFK, which will be displayed in our ILS receiver instrument or you have to actually listen to the morse code and compare it to the one on your ILS approach chart. Please comment below what type of plane you´re flying if you still have to self tune the ILS frequency and listen to the morse code. But see more within the video! Thank you very much for your time, wishing you all the best your "Captain" Joe BIG THANK YOU TO Robert Bremmer for supporting my channel with his short animation about the ILS and Marker beacons.

Curiosity : Communication
 
02:57
This animation shows how orbiters over Mars will monitor the landing of NASA's Curiosity rover. Curiosity will communicate with Earth via two of NASA's Mars orbiters, Mars Reconnaissance Orbiter and Odyssey. As the rover descends to the surface of Mars, it will send out two different types of data: basic radio-frequency tones that go directly to Earth (pink dashes) and more complex UHF radio data (blue circles). Odyssey will pick up the UHF signal and relay it immediately back to Earth (seen as a beam of small blue circles). Meanwhile, Mars Reconnaissance Orbiter will record the UHF data and play it back to Earth at a later time. Back on Earth, the rover's signals are picked up by large antenna dishes at NASA's Deep Space Network (DSN), which has three complexes in Goldstone, Calif., Madrid, Spain and Canberra, Australia. The DSN sends the information to Curiosity's mission control at NASA's Jet Propulsion Laboratory, Calif. As the rover descends to Mars, it will send out basic radio-frequency tones that go directly to Earth. NASA's Odyssey orbiter will then relay more complex UHF radio signals from the rover to Earth. NASA's Mars Reconnaissance Orbiter will fly over NASA's Curiosity (shown in pink) as the rover lands on the Red Planet. The video is slowed down as the orbiter approaches the landing site for better viewing. Mars Reconnaissance Orbiter will capture data during Curiosity's entry, descent and landing for later playback to Earth. Its High Resolution Imaging Science Experiment (HiRISE) camera will attempt to take an image of Curiosity as it descends to the surface (green). HiRISE is one of six instruments on NASA's Mars Reconnaissance Orbiter.

I still have no idea yet what this is...I innocently raised it 12 tones and this is what appeared. I dont mean it to be 'scare-mungoring' its just to my mind (as a musician) it has definite patterns to the ear..whether speech, asteroids, magnetic waves, im not qualified to say, but all I know is...its an interesting pattern...JVD Important info - Please read: Speech patterns have been found in a radio signal released by NASA almost 3 years previously in 2004. Judge the sound for yourself, it is a very bizarre anomaly but very much worth investigating. Instructions: 1) Download and save the original WAV file from NASA/Cassini website: http://saturn.jpl.nasa.gov/multimedia/images/saturn/audio/pia07967-072504.wav 2)Open an audio editor like Cool Edit or Sonar and raise the pitch/frequency of the file by 12 tones with the pitch shifter... and there it is, speech patterns. How can anyone explain this anomaly? Certainly, NASA has no explanation for it after we presented the file to them for their opinion. SETI also don't know what make of it. What do you think?

What You Need To Know About HD Radio
 
04:33
How does it work? HD Radio technology works pretty much just like traditional analog radio transmission: -The radio station sends out the analog and digital radio signals, along with a third signal for text data. -The digital signal is compressed before being transmitted. -The three-layered signal is transmitted from the radio station's upgraded digital transmitter. -Multipath interference, caused by the signal reflecting off of buildings, is ignored by the digital radio, which is able to discern the true signal and ignore interference. -Your radio receives the signal and, depending on your equipment, you hear either the digital or analog feed. *FM radio that sounds almost as good as a CD Digital technology allows a radio station to transmit more information in the same radio wave. Primarily, this means higher quality sound. So much more so that FM transmissions can sound nearly as good as CDs, and definitely much better than the hollow sounds of old analog FM. How much better the music sounds will depend on your local stations and your radio gear. *AM radio that sounds as good as traditional FM AM radio uses smaller sections of bandwidth than FM. There is not enough bandwidth for HD Radio to give AM stations the same CD-quality signal as FM stations. But there is enough room to give AM stations clarity equivalent to current analog FM stereo radio. This boost in sound quality makes AM radio a viable alternative to FM, which means more options for listeners. *No more static, pops, crackles or fades...and no subscription fees The digital signal is less vulnerable to reception problems. The radio tuner's digital processors eliminate the static, pops, hisses, and fades caused by interference. You hear only clear, clean, and rich sound. Should you lose the digital signal for some reason (obstructing terrain, nearing the edge of the broadcast area, etc.), HD Radio technology defaults back to analog mode, similar to the way non HD Radio receivers switch from stereo to mono mode when receiving a weak signal. And like analog radio, HD Radio is subscription-free. *Displayed information, including station ID info, song and artist titles, weather, traffic, and emergency alerts Another benefit of digital radio is the radio station's ability to transmit additional information along with the music signal. This can take the form of scrolling text on your receiver's display, such as a song's artist and title and station call letters. HD Radio also supports Artist Experience — with compatible receivers you can view album art, logos, and more, when provided by the station. Stations can also include local and regional information, such as weather updates, emergency alerts, or even traffic jams and road construction. Traffic data is delivered up to 10 times faster than other broadcast methods. *Increased listening options with station multicasting In addition to duplicating their analog programming with an HD Radio broadcast, stations can subdivide the digital portion of their signal. This allows a station to "multicast" — that is, broadcast two or more programs simultaneously. Listeners might have a choice of, say, a sports game or music. These additional channels can only be received on an HD Radio tuner. But just as cable TV allowed specialized networks to flourish, multicasting provides the potential for stations to offer more niche programming — ultimately giving the listener a greater variety of formats to choose from.

U.S. NAVY SIGNAL CORPS FLAG SEMAPHORE /  BLINKER / MORSE CODE TRAINING FILM  85664
 
25:23
This fascinating 1943 U.S. Navy training film shows "How to Signal" using flag hoists, semaphore, and blinker to present morse code messages. The film was produced by F.H. Hargove of the Prior Motion Picture Company in New York and supposedly narrated by "Radcliffe Hall" (like a pseudonym for a radio announcer). A review in "Motor Boating" magazine noted that "the film shows pictorially how to learn the codes in the International Flag, Semaphore and Blinker systems of Communication. Expert signal men in the U.S. service serve as instructors and demonstrate the correct methods of using these three methods. It is designed so that the film may be repeated again and again until the student becomes familiar with the signal flags and positions of the semaphore, and the light flashes of the blinker…" Flag semaphore is the telegraphy system conveying information at a distance by means of visual signals with hand-held flags, rods, disks, paddles, or occasionally bare or gloved hands. Information is encoded by the position of the flags; it is read when the flag is in a fixed position. Semaphores were adopted and widely used (with hand-held flags replacing the mechanical arms of shutter semaphores) in the maritime world in the 19th century.[citation needed] It is still used during underway replenishment at sea and is acceptable for emergency communication in daylight or, using lighted wands instead of flags, at night. The use of lights for spelling out messages in Morse code dates back to 1867. With the advent of electric lights in the 1890s, the "blinker light" became an effective tool for signaling. Most widely used by naval ships, blinker lights were essential for merchant ships sailing in wartime convoys and observing radio silence. Blinker has remained a useful backup for merchant vessels, and until the late 1980s deck officers were trained in its use. Usually however, blinker work was done by the Radio Officer. Beginning in the 1930s, both civilian and military pilots were required to be able to use Morse code, both for use with early communications systems and for identification of navigational beacons which transmitted continuous two- or three-letter identifiers in Morse code. Aeronautical charts show the identifier of each navigational aid next to its location on the map. Radio telegraphy using Morse code was vital during World War II, especially in carrying messages between the warships and the naval bases of the belligerents. Long-range ship-to-ship communication was by radio telegraphy, using encrypted messages, because the voice radio systems on ships then were quite limited in both their range and their security. Radiotelegraphy was also extensively used by warplanes, especially by long-range patrol planes that were sent out by those navies to scout for enemy warships, cargo ships, and troop ships. Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. The International Morse Code encodes the ISO basic Latin alphabet, some extra Latin letters, the Arabic numerals and a small set of punctuation and procedural signals (prosigns) as standardized sequences of short and long signals called "dots" and "dashes", or "dits" and "dahs", as in amateur radio practice. Because many non-English natural languages use more than the 26 Roman letters, extensions to the Morse alphabet exist for those languages. Each Morse code symbol represents either a text character (letter or numeral) or a prosign and is represented by a unique sequence of dots and dashes. The duration of a dash is three times the duration of a dot. Each dot or dash is followed by a short silence, equal to the dot duration. The letters of a word are separated by a space equal to three dots (one dash), and the words are separated by a space equal to seven dots. The dot duration is the basic unit of time measurement in code transmission. To increase the speed of the communication, the code was designed so that the length of each character in Morse varies approximately inversely to its frequency of occurrence in English. Thus the most common letter in English, the letter "E", has the shortest code, a single dot.

Writing in the Astronomer's Telegram, scientists reported 15 fast radio bursts detected from a dwarf galaxy some 3 billion light years from our own. Scientists suggest the bursts may have come from a magnetar, which is a rotating neutron star with a strong magnetic field. Researchers also speculate that the bursts may originate from alien laser technology used to propel and power spacecraft, like wind powers sails on a ship, according to a University of California, Berkeley news release. That theory is similar to Breakthrough Starshot, an initiative aimed at propelling nanocraft to Proxima Centauri with Earth-based lasers.

Distant Galaxy Sends Out 15 High-Energy Radio Bursts
 
05:57
A sequence of 14 of the 15 detected bursts illustrate their dispersed spectrum and extreme variability. The streaks across the colored energy plot are the bursts appearing at different times and different energies because of dispersion caused by 3 billion years of travel through intergalactic space. In the top frequency spectrum, the dispersion has been removed to show the 300 microsecond pulse spike. Capturing this diverse set of bursts was made possible by the broad bandwidth that can be processed by the Breakthrough Listen backend at the Green Bank Telescope.

Mysterious radio signals have long been a mainstay of science fiction tales, but lately they’ve also been the subject of serious scientific scrutiny. Radio bursts originating from deep space have become a hot topic in the astronomy world, and while most of these appear to be naturally occurring, you never know when one of them turns out to be something far stranger. At least, we can hope one of them will. Here on boring planet Earth, mysterious radio signals often pop up in the form of pirated transmissions broadcasting strange, cryptic messages. While most of these turn out to be merely hoaxes or pranks, many of them also remain unexplained. #Unexplained Mysteries ******************************************************************** ****Like, share and comment if you like Truth News**** **Thank you for watching Truth News !** * Channel : https://bit.ly/TruthNews * Twitter : https://twitter.com/TruthNews2019 * Facebook : https://www.facebook.com/TruthNews2019

Cassini Finds Saturn Sends Mixed Signals [720p]
 
02:22
Recent data from NASA's Cassini spacecraft show that the variation in radio waves controlled by the planet's rotation is different in the northern and southern hemispheres. Moreover, the northern and southern rotational variations also appear to change with the Saturnian seasons, and the hemispheres have actually swapped rates. These two radio waves, converted to the human audio range, can be heard in a new video available online at: http://www.nasa.gov/multimedia/videogallery/index.html?media_id=74390781 "These data just go to show how weird Saturn is," said Don Gurnett, Cassini's radio and plasma wave science instrument team lead and professor of physics at the University of Iowa, Iowa City. "We thought we understood these radio wave patterns at gas giants, since Jupiter was so straightforward. Without Cassini's long stay, scientists wouldn't have understood that the radio emissions from Saturn are so different." read more at http://www.jpl.nasa.gov/news/news.cfm?release=2011-091 credit: NASA/JPL source: http://www.jpl.nasa.gov/video/index.cfm?id=976

Dr George Carlo speaks on wi-fi radiation schools PT.2
 
09:04
http://www.emfnews.org A cellular phone is basically a radio that sends signals on waves to a base station. The carrier signal generates two types of radiation fields: a near-field plume and a far-field plume. Living organisms, too, generate electromagnetic fields at the cellular, tissue, organ, and organism level; this is called the biofield. Both the near-field and far-field plumes from cell phones and in the environment can wreak havoc with the human biofield, and when the biofield is compromised in any way, says Dr. Carlo, so is metabolism and physiology. "The near field plume is the one we're most concerned with. This plume that's generated within five or six inches of the center of a cell phone's antenna is determined by the amount of power necessary to carry the signal to the base station," he explains. "The more power there is, the farther the plume radiates the dangerous information-carrying radio waves." A carrier wave oscillates at 1900 megahertz (MHz) in most phones, which is mostly invisible to our biological tissue and doesn't do damage. The information-carrying secondary wave necessary to interpret voice or data is the problem, says Dr. Carlo. That wave cycles in a hertz (Hz) range familiar to the body. Your heart, for example, beats at two cycles per second, or two Hz. Our bodies recognize the information-carrying wave as an "invader," setting in place protective biochemical reactions that alter physiology and cause biological problems that include intracellular free-radical buildup, leakage in the blood-brain barrier, genetic damage, disruption of intercellular communication, and an increase in the risk of tumors. The health dangers of recognizing the signal, therefore, aren't from direct damage, but rather are due to the biochemical responses in the cell. Here's what happens:  Cellular energy is now used for protection rather than metabolism. Cell membranes harden, keeping nutrients out and waste products in.  Waste accumulating inside the cells creates a higher concentration of free radicals, leading to both disruption of DNA repair (micronuclei) and cellular dysfunction.  Unwanted cell death occurs, releasing the micronuclei from the disrupted DNA repair into the fluid between cells (interstitial fluid), where they are free to replicate and proliferate. This, says Dr. Carlo, is the most likely mechanism that contributes to cancer.  Damage occurs to proteins on the cell membrane, resulting in disruption of intercellular communication. When cells can't communicate with each other, the result is impaired tissue, organ, and organism function. In the blood-brain barrier, for example, cells can't keep dangerous chemicals from reaching the brain tissue, which results in damage. With the background levels of information-carrying radio waves dramatically increasing because of the widespread use of cell phones,Wi-Fi, and other wireless communication, the effects from the near and far-fields are very similar. Overall, says Dr. Carlo, almost all of the acute and chronic symptoms seen in electrosensitive patients can be explained in some part by disrupted intercellular communication. These symptoms of electrosensitivity include inability to sleep, general malaise, and headaches. Could this explain the increase in recent years of conditions such as attention-deficit hyperactivity disorder (ADHD), autism, and anxiety disorder? "One thing all these conditions have in common is a disruption, to varying degrees, of intercellular communication. When we were growing up, TV antennas were on top of our houses and such waves were up in the sky. Cell phones and Wi-Fi have brought those things down to the street, integrated them into the environment, and that's absolutely new. The recognition mechanism, where protein vibration sensors on the cell membrane pick up a signal and interpret it as an invader, only works because the body recognizes something it's never seen before." As to increases in brain tumors tied to cell phone use, it's too early to tell due to a lack of hard data, says Dr. Carlo. "We're never going to see that in time to have it matter. Here in the US, we're six years behind in getting the brain tumor database completed, and currently the best data are from 1999. By the time you see any data showing an increase, the ticking time bomb is set." Epidemic curve projections, however, indicate that in 2006, we can expect to see 40,000 to 50,000 cases of brain and eye cancer. This is based on published peer-reviewed studies that allow calculation of risk and construction of epidemic curves. By 2010, says Dr. Carlo, expect that number to be between 400,000 and 500,000 new cases worldwide. To learn more go to http://www.emfnews.org

Pluto in a Minute: How Did New Horizons Phone Home?
 
01:47
New Horizons phoned home! But how exactly does a spacecraft talk to us from 3 billion miles away? This is Pluto in a Minute. After being silent for nearly 22 hours on July 14, as planned, New Horizons did send a status report back to the mission team to let them know that the spacecraft was ok. But how does a signal travel to Earth from Pluto and how long does it take? New Horizons sends and receives data on radio waves, which are the waves on the long end of the electromagnetic spectrum. Because they're on the electromagnetic spectrum, radio waves travel at the speed of light. It takes sunlight about 8.3 minutes to travel 1 astronomical unit or 1 AU, that is, the distance between the Sun and the Earth. Pluto is currently about 32 AU from Earth, so 32 times 8.3 is about 265 (minutes). So the one way light time delay for the mission team to talk to New Horizons is about 4 and a half hours each way. The signal left the spacecraft at about 4:27 in the afternoon on July 14. Traveling at the speed of light, that phone home signal crossed Neptune's orbit about 25 minutes later. Then the signal traveled about hour and 28 minutes before crossing Uranus' orbit. The signal reached Saturn's orbit about hour and 28 minutes later, and then crossed Jupiter's orbit another 28 minutes after that. Then an additional 33 minutes for the signal to reach Mars' orbit, and then 7 minutes for it to go from Mars to the Earth. And in the time that it just took me to explain exactly when that phone home signal crossed the planets' orbits, a signal from or to New Horizons would not have moved very much at all. For more on Pluto be sure to check out the New Horizons websites and also tweet your questions using the hashtag #PlutoFlyby. And of course, come back tomorrow for more Pluto in a Minute. http://www.nasa.gov/newhorizons http://pluto.jhuapl.edu

Zoom close to radar data curtain in the Hiawatha Impact Crater
 
00:11
This region of the Hiawatha impact crater has been studied using ice-penetrating radar. The ice radar sends out radio waves into the ice sheet and collects the data reflected back from within the ice sheet and the ground beneath. The reflected data depicts the historical layers in the ice generated by the annual seasonal cycles of growth and melt. The radar data is then displayed on curtains in the location where it was observed showing the layers in the ice that record its history. This visualization shows the bed beneath the Hiawatha Glacier and some of the radar curtains. Here the topography of the bed and the radar curtains have been exaggerated ten times in order to better view their features. These layers visible in the radar curtain record the history of the ice sheet from the oldest ice near the bed to the recent year's layers found near the surface. Note the disturbance in the layers found close to the bed. The Hiawatha impact crater was first suspected to exist in 2015, from examination of a compilation of Greenland's sub-ice topography radar measurements made by NASA over two decades. The visualizations of the subsurface shown below are derived from a spring 2016 airborne survey by Germany's Alfred Wegener Institute, using a new ultrawideband radar sounder developed by the Center for Remote Sensing of Ice Sheets (CReSIS) at The University of Kansas. Subsequent helicopter visits to the deglaciated terrain in front of Hiawatha Glacier by scientists from the Natural History Museum in Denmark recovered sediment samples from the main river that discharges water from beneath Hiawatha Glacier, through the northwestern rim breach. Laboratory examination revealed that these sediment samples contained shocked quartz and elevated platinum-group-element concentrations, both signs that the sediment records evidence of the impact of a iron asteroid more than one kilometer wide. The Hiawatha impact crater is likely one of the youngest large impact craters on Earth.

How Radar works ? | General science for civil service exam | General knowledge

How Radar works ? | General science for civil service exam | General knowledge Imagine trying to land a jumbo jet the size of a large building on a short strip of tarmac, in the middle of a city, in the depth of the night, in thick fog. If you can't see where you're going, how can you hope to land safely? Airplane pilots get around this difficulty using radar, a way of "seeing" that uses high-frequency radio waves. Radar was originally developed to detect enemy aircraft during World War II, but it is now widely used in everything from police speed-detector guns to weather forecasting. Let's take a closer look at how it works! What is radar? We can see objects in the world around us because light (usually from the Sun) reflects off them into our eyes. If you want to walk at night, you can shine a torch in front to see where you're going. The light beam travels out from the torch, reflects off objects in front of you, and bounces back into your eyes. Your brain instantly computes what this means: it tells you how far away objects are and makes your body move so you don't trip over things. Radar works in much the same way. The word "radar" stands for radio detection and ranging—and that gives a pretty big clue as to what it does and how it works. Imagine an airplane flying at night through thick fog. The pilots can't see where they're going, so they use the radar to help them. An airplane's radar is a bit like a torch that uses radio waves instead of light. The plane transmits an intermittent radar beam (so it sends a signal only part of the time) and, for the rest of the time, "listens" out for any reflections of that beam from nearby objects. If reflections are detected, the plane knows something is nearby—and it can use the time taken for the reflections to arrive to figure out how far away it is. In other words, radar is a bit like the echolocation system that "blind" bats use to see and fly in the dark. How radar works Whether it's mounted on a plane, a ship, or anything else, a radar set needs the same basic set of components: something to generate radio waves, something to send them out into space, something to receive them, and some means of displaying information so the radar operator can quickly understand it. The radio waves used by radar are produced by a piece of equipment called a magnetron. Radio waves are similar to light waves: they travel at the same speed—but their waves are much longer and have much lower frequencies. Light waves have wavelengths of about 500 nanometers (500 billionths of a meter, which is about 100–200 times thinner than a human hair), whereas the radio waves used by radar typically range from about a few centimeters to a meter—the length of a finger to the length of your arm—or roughly a million times longer than light waves. Both light and radio waves are part of the electromagnetic spectrum, which means they're made up of fluctuating patterns of electrical and magnetic energy zapping through the air. The waves a magnetron produces are actually microwaves, similar to the ones generated by a microwave oven. The difference is that the magnetron in a radar has to send the waves many miles, instead of just a few inches, so it is much larger and more powerful. Once the radio waves have been generated, an antenna, working as a transmitter, hurls them into the air in front of it. The antenna is usually curved so it focuses the waves into a precise, narrow beam, but radar antennas also typically rotate so they can detect movements over a large area. The radio waves travel outward from the antenna at the speed of light (186,000 miles or 300,000 km per second) and keep going until they hit something. Then some of them bounce back toward the antenna in a beam of reflected radio waves also traveling at the speed of light. The speed of the waves is crucially important. If an enemy jet plane is approaching at over 3,000 km/h (2,000 mph), the radar beam needs to travel much faster than this to reach the plane, return to the transmitter, and trigger the alarm in time. That's no problem, because radio waves (and light) travel fast enough to go seven times around the world in a second! If an enemy plane is 160 km (100 miles) away, a radar beam can travel that distance and back in less than a thousandth of a second.
