This very simple, very easily executable solution to a problem that is growing. The Frequencies are already allocated to the airline industry and a simple piece of equipment (non expensive) can be installed. You can find the full article here.
The International Telecommunication Union (ITU) has allocated radio spectrum for global flight tracking for passenger aircraft using satellite-based systems.
The move follows developments spurred by the so far unexplained disappearance of Malaysia Airlines Flight 370 in March last year, which prompted the aviation community to look into possibilities of constant monitoring of passenger planes in flight.
The frequency band of 1087.7-1092.3MHz has been allocated, which is already being used for data transmissions between planes and terrestrial stations that are within the line of sight.
Extending the system to cover also communications between planes and satellites and satellites and terrestrial stations will enable creating a complex system capable of tracking passenger planes throughout the flight even over oceans and remote areas.
The ITU agreed on the allocation at its 2015 World Radiocommunication Conference following a call by the International Civil Aviation Organisation (ICAO).
Performance criteria for satellite reception of the signals will be established by ICAO.
“In reaching this agreement at WRC-15, ITU has responded in record time to the expectations of the global community on the major issue concerning global flight tracking,†said ITU Secretary-General Houlin Zhao. “ITU will continue to make every effort to improve flight tracking for civil aviation.â€
ITU has been working on standards to facilitate the transmission of flight data in real time since early after the MH370 disaster.
Already in April 2014, less than a month after the aircraft’s disappearance, Malaysian Minister for Communications and Multimedia called upon ITU to address the issue.
“The allocation of frequencies for reception of ADS-B signals from aircraft by space stations will enable real-time tracking of aircraft anywhere in the world,†said François Rancy, Director of the ITU Radiocommunication Bureau. “We will continue to work with ICAO and other international organizations to enhance safety in the skies.â€
In October 2014, the ITU Plenipotentiary Conference meeting in Busan, Republic of Korea, instructed WRC-15 to consider global flight tracking in its agenda.

Guide To Which Motorola Connector You Need
Since the 1920’s Motorola has been leading the advancement of radio technology in more ways than one. From the battery eliminator created in 1928 to the world’s first handheld public safety LTE device created in 2012, Motorola truly has been an innovator in the radio world.
There was one of Motorola’s products that stood out and started paving the way for the Motorola brand name. That was their two-way radio systems. In 1978 Motorola introduced the RDX1000. This device was a portable data terminal. With a built-in keyboard and advanced transmitters, The RDX1000 made it possible for a person to share information, like inventory control, wirelessly with a central computer system. It is because of advancements and products like the RDX1000 that Motorola was awarded the National Medal of Technology twice.
Yet, even with being the one of the leading technological companies they still had their issues. For example, the connectors used for their devices, usually, were confusing and weren’t universal like most of our tech is today. Yes, with being in the lead of the industry with innovative products they needed new forms of connectors and pieces that couldn’t exactly be matched by other companies. To be more specific, the connectors to the Motorola earpieces came with their own specific confusions.
Over the course of the years, Motorola devices have had over 50 different types of earpiece connectors. Motorola earpieces are specific to their devices so the pieces chosen had to be precisely specific to the device it was being matched with. You can imagine, with over 50 different types of connectors, finding the correct corresponding puzzle piece that would fit was imperative. The confusion wasn’t just limited to a small portion of the Motorola accessories. Motorola earpieces were different by model of the same device as well. With the earpieces you can’t exactly go by looks either. Most of the earpieces look very similar with very subtle difference.
Even though some had connectors with very similar differences. Differences ranging from appearance and size of the connector to the type of material used in the pin of the connector itself. This confusion also spans over several different years of manufacturing as well. With connectors from earlier years being a small series of pins in lateral form that would only connect to the proper outlet with the proper series of pins. Or like the single pin connector that would only be in a specific size per model, you wouldn’t exactly be able to take a Kenwood connector and confuse it with a Motorola 2-pin connector because on these connectors the pins are of a different size to the Kenwood. Some specific connectors can be understood considering the advancing of the technology as well as the device it connects to has some significance.
The importance of the device does have some control over the type of connector used as well. Because you don’t want to issue and offer a radio and have to worry about it getting lost or stolen and being used for an inappropriate purpose. But, you would expect a device in the same model family to be able to connect or at least the connectors to be somewhat interchangeable. This isn’t the case with Motorola radios. For example, The DP2400 two way radio takes a Clip on block style of connector. While the DP3400 responder radio has to have a Screw in Block  connector in order for the product to be used properly. Even though the station and responder radio are two different products, they share similarities and commonalities. Also you would expect them to share the same connector.
Unfortunately this is the case with many of the Motorola earpieces .

Can you hear radio broadcasts through your teeth?
Do you mean me specifically? If so, then the answer is ‘no’ I’m afraid. I must also say that given the state of pop music these days, I’m actually very glad of it!
So...Awkward question time: are you hearing radio broadcasts through your teeth mate?
Lol. Just kidding.
Whilst it sounds like utter nonsense, there have actually been quite a few reported cases of people ‘picking up’ radio broadcasts through their fillings/dental caps over the years.
Our oft-quoted friend Cecil Adams, of The Straight Dope.com, actually answered this question back in 1992. In his answer, Adams highlighted two particularly interesting case studies. I’ll reprint them here, along with a link to the site in question.
Case #1. George, of suburban Chicago, lost a front tooth at the age of 12. A year or so later, in about 1961, he was fitted with a cap that was attached to the tooth stump with what George recalls as a brass wire. Thereafter he began hearing music in his head, generally popular tunes of the day, usually while he was outdoors. The music was soft but distinct. He never heard an announcer's voice or commercials and was unable to identify what radio station, if any, he was hearing. After a year or two of this a new dentist put in a cap without a wire and the tunes stopped.
Case #2. Lois, also of suburban Chicago, says it happened just once, in 1947, while she was riding a train from her home in Cleveland to college in Rhode Island at about age 18. The experience lasted maybe 10 minutes. She couldn't tell what station she was listening to but recalls hearing commercials and an announcer's voice. She has silver tooth fillings but doesn't recall if she'd had one put in just before the event.
Actress Lucille Ball even claimed to have helped the allies by intercepting radio signals in this, frankly rather bizarre, way. This story is widely re-told and was even used as part of the plot of the musical ‘Something For The Boys’.
Adams goes on to mention a piece on Snopes.com about the incident, which appears to feature the testimony of the actress herself, who says,
“One night I came into the valley over Coldwater Canyon, and I heard music. I reached down to turn the radio off, and it wasn’t on. The music kept getting louder and louder and then I realized it was coming from my mouth. My mouth was humming and thumping with the drumbeat and I thought I was losing my mindâ€
According to the Snopes account, after she related this strange story to Buster Keaton, he told her that it had happened to a friend of his.
If you’re interested, here’s Lucille’s account of ‘catching’ the Japanese spies, which allegedly transpired about a week later.
“All of a sudden, my mouth started jumping. It wasn’t music this time, it was Morse code. It started softly and then DE-DE-DE-DE DE-DE-DE-DE! As soon as it started fading, I stopped the car and then started backing up until it was coming in at full strength. DE-DE-DE-DE DE-DE-DE-DE! I tell you, I got the hell out of there real quick. The next day, I told the MGM security office about it, and they called the FBI or something and sure enough, they found an underground Japanese radio station. It was somebody’s gardener, but sure enough, they were spiesâ€
As entertaining as Lucille’s story is, Snopes could find no record of the event, which surely would have been heavily featured in the local, if not the national, news. A cover-up to prevent mass panic? Personally, I don’t think so, as Snopes goes on to mention a Japanese submarine being spotted off the coast of Santa Barbara on February 23rd 1942, which was obviously an extensively covered event.
A discussion on Skeptics Stack Exchange.com uncovers another major flaw in this story (and all others like it). The users suggest (rightly) that any radio signal must first be demodulated in order to make any sense at all. As far as I know, dental fillings have no demodulation circuits.
So, is it possible or not?
Probably not. A demodulation circuit is not and has never been a part of a dental filling’s mix-up.
There is some compelling ‘evidence’ out there, as well as a couple of cases that have been looked into somewhat scientifically and featured in various respected journals, but then again, according to certain statistics, 3.7 million Americans have been abducted by aliens. That alarming statistic, in and of itself, ought to be enough to make you skeptical of anything.

How to Hide a Radio Earpiece
A 2 way radio earpiece is an accessory which can receive and transmit unlike the broadcast receivers which only receive content. 2 way radio earpieces allow the user to engage in conversations with other such radio earpieces that are operating on a similar radio frequency. 2 way radios are readily available in hand held, mobile and stationary base configurations. The hand held radios are usually known as walkie talkies or handie-talkies.
2 way radio systems normally operate in 1/2 duplex mode; this basically means that the user can listen or talk, but cannot do both at a go. A PTT (also known as press to transmit) button usually activates the radio's transmitter. When the button is released, its' receiver becomes active. For 2 way radio earpieces, a push to talk button is included on a wire that runs up the arm of the user, with an acoustic tube up to the ear.
There are 2 wires which run independently from the 2 way radio; one ends at the PTT and mic, while the other ends at the radio's earpiece. The 2 wire kits are worn under the clothing, running one cable from the 2 way radio, up to your ear. The other cable runs from the 2 way radio, up your back and down your sleeve to the cuffs of your long sleeved shirt or clipped by a lapel on the front of your shirt. 3 wire kits separate the Mic and PTT with one cable running down the arm, connected to the PTT, another connected to the mic, with normally includes a microphone which is clipped to the jacket or shirt and the third has the acoustic tube to go into the ear.
You can run the wires underneath the shirt; hiding the wires from the 2 way radio to the earpiece underneath your clothing, offering more discreetness. If you aren't too concerned with discreetness, you can leave the wires outside of your clothing. The radio will work either way. Here are the steps on how to hide a radio earpiece;
Take the wires of the radio earpiece and run them inside your shirt. Now take the wires out from your shirt's top; this way the wires will be well hidden. Take your earpiece and then put it in one ear. Ensure, the earpiece fits tightly and wont fall when walking, you can put the earpiece in either ear.
Once you're comfortable with your earpiece, it is now time to fit the wires that go into the radio. Take the wire that connects the earpiece and the radio, and fit it inside the shirt. Take this wire out from your shirt's bottom. Put it in your radio, and then clip the radio properly on your belt. Once all the wires are properly fitted inside your shirt, you can now tuck in the shirt to hide them completely.
Once everything is properly fitted, switch on your 2 way radio and test it. Now, you can use your 2 way radio earpiece covertly
The real benefit of using a hidden radio earpiece, is that other people will not notice when you're talking on your earpiece, remember to never share radio earpieces; this is for health and sanitary purposes. You can also buy radio earpieces, along with your own personal ear tips and clear coils.
