World Radio Day focuses on role of radio in disaster management

World Radio Day on 13 February brings attention to the role of radio in managing disasters and recovery in their aftermath.



Radio is recognized as a low-cost medium, specifically suited to reach remote communities and is especially effective in reaching people affected by disasters when other means of communication are disrupted. Terrestrial radio broadcasts are effective in providing timely, relevant and practical information to people who are confused and demoralised by the impact of a crisis. Broadcast information is particularly useful in situations where physical access is difficult and aid responders may take several days or weeks to reach affected communities.



Recent natural and man-made disasters are a major cause for concern to the global community. “In times of crisis and emergency, radio can be a lifeline,” said United Nations Secretary-General Ban Ki-moon. “For people in shattered societies, or caught in catastrophe, or desperately seeking news, radio brings lifesaving information. This year, as we start carrying out the Sustainable Development Goals, let us resolve to use radio for human progress. On this World Radio Day, let us resolve to prove that radio saves lives.”

“Radiocommunication is indispensable in saving lives in the event of a natural disaster,” said ITU Secretary-General Houlin Zhao. “Collaborating and sharing experiences is critical in order to support national and regional preparedness, and ITU is deeply committed to facilitating rapid and effective response in emergencies.”

“Amidst the ruins and in the face of an emergency, the radio is often the first medium for survival,” says Irina Bokova, Director-General of UNESCO. “Its durability is an incomparable advantage, often enabling it to resist shocks and re-transmit messages of protection and prevention to as many people as possible, better and faster than other media, saving lives.”

New developments in radio technology and in the transmission and delivery of radio content, especially through mobile devices and through on-demand media platforms, further extend the means to engage disaster-affected communities. These digital innovations are increasingly important in delivering effective disaster preparedness and prevention, while reinforcing the importance of community radio services.

ITU has developed a number of standards for effective emergency radiocommunications, recognizing that direct communication via radio helps reduce the sense of isolation and helplessness experienced by crisis-affected communities. Recommendation ITU-R BT.1774-2 is the standard that relates to emergency warning systems for analogue broadcasting, which facilitates the use of satellite and terrestrial broadcast infrastructures for public warning, disaster mitigation and relief.

In addition, the 2015 ITU World Radiocommunication Conference (WRC-15) identified spectrum to facilitate mobile broadband communications for robust and reliable mission-critical emergency services in public protection and disaster relief (PPDR), such as police, fire, ambulances and disaster response teams. WRC-15 also reinforced protection to search and rescue beacons to uplink to satellites, such as the Cospas-Sarsat system, which has assisted in rescuing over 37,000 people worldwide since December 2013.

World Radio Day marks the anniversary of the first broadcast by UN Radio in 1946, when it transmitted its first call sign: “This is the United Nations calling the peoples of the world.” Ever since, UN Radio broadcasts have highlighted the principles of the United Nations to foster world peace and development. World Radio Day seeks to raise awareness about the importance of radio, facilitate access to information through radio, and enhance networking among broadcasters.

They said that waterproof Two way radios would never exist, well they had better read this

Icom two way radios are well known in the marine and coastal industries. Why are these so well known in these industries? That is because the F1000 and F2000, along with the F1000D and the F2000D are all waterproof, being able to be submersed to a depth of 1 meter for a maximum of 30 minutes, that means that these radios can be used confidently on a boat, ship or other water fairing vessel and be splashed around before it starts smoking and sparking everywhere! The IP67 waterproof casing means that it is made for total protection against dust and dirt and can withstand immersion between 15cm and 1m.

When we talk about sound, we expect the highest quality of two way radios to have the best speakers producing the best output possible, but the icom website explains it like this “The large 36mm speaker of the transceiver provides clear commanded 800 mW audio. The built-in BTL amplifier doubles the audio output power and delivers loud and intelligible voice to a radio operator working in noisy environments” which basically means it produces some of the best sound out one of the smallest speakers on the market.

So let’s go over the radios themselves, something that isn’t so obvious is that they have split the frequency bands of the radios, the F1000’s is VHF only and the F2000’s is UHF. This is a brilliant idea from the guys at Icom, users often find it difficult to wade through a lot of the jargon of two way radios, so separating out the radio types into their respective bands goes a long way to remove the confusion.

You may have noticed that there are 2 choices for each F radio, the F1000 and the F1000 D the D relates to the radios being digital compatible, meaning it can be programmed to be used on current digital systems as well used as a normal two-way radio. Analogue and Digital capable so that it can do both jobs or be ready for when you expand and move to a digital system.



Over the years Icom have been consistent with their accessory connectors , a large range of their radios use the 2 pin connector, the only exception was the small multi connector that they introduced a few years ago. But these new F1000 & F2000 radios have been given their very own connector, very similar to the first generation but will not work with those radios, the new connector includes 2 holding screws. The range of F1000 radio earpieces is huge, with plenty to choose from, you will find any type of radio earpiece for these F1000 and F2000 radios.

If you are looking for a waterproof radio used by many in the marine industry then the F1000 or F2000, depending on your frequency allocation, would be a great choice. It can be dropped to a depth of 1 meter for 30 minutes, so if you worry about splashes on your radio or it sitting in a pool of water on your boat, then you can be assured that it won’t damage this radio. With the latest technology and digital capabilities these are as modern as many counter-parts in the digital two way radio market.

Can Two Way Radios of Different Brands Communicate

One question that is frequently asked by people interested in buying two way radios is that can you mix brands of two way radios. To answer this question properly, it is imperative to understand first how the devices work. It should be known that whether you have a small business or a large warehousing facility, UHF band radios never communicate with the VHF band radios. Therefore, if you are looking to buy a radio, make sure to buy additional units of the device of similar bands. In this way be it a UHF band radio or a VHF band radio, if set to the same frequency can work with all brands. However, some considerations have to be put in its place beforehand.

Functionality

Two way radios imply that it can both send as well as receive radio messages. They are transceivers that are battery powered. The radios operate on a half-duplex channel system. This system implies that the radio will be able to transmit a signal on a single channel that can be received on many devices at the same time. Normally these radios are designed to transmit short-range signals. Almost all of the two way radios function on the same principle. They all include a microphone, an antenna, a speaker, and the Push to talk Button. These radios are designed to function on different frequencies.

Frequency types

The general public use frequencies are the Family radio service frequency or the FRS and the general Mobile radio Service frequency or GMRS. Both these frequencies work on a 460 MHz rage. The UHF frequency or the ultra-high frequency is ideal for the two way radios as they can easily penetrate the interference in the form of building and trees. The two way radio with a long UHF antenna will push through the concrete and will do your work efficiently. On the other hand, VHF antennas on the radios are much longer than the ones in the UHF radios. These are ideal to use in the outdoors as they usually can transmit signals over very large distances.

Types of radios

There are normally two types of radios, that are used in businesses and that are used in consumer situations. The consumer radios normally work on the FRS or the GMRS frequencies. Regardless of the number of channels in the radio, the two way radios can be mixed with other brand radios. Only the radios have to be set to the same privacy code, the channel number, and the same frequency. Alternatively, there are several different types of frequency in the business two way radios category. The radios use the UHF, VHF and the 800/900 MHz type frequency. Just by choosing, the radio with the same frequency may not be compatible with the radios of other brands bought beforehand. While buying the radio, the dealer may have programmed a special customized frequency into the radio beforehand. In order for the business, two way radios to work efficiently with the radios of different brands it is essential to completely figure the type of band that the radio uses, the pre-set frequency on the radio from the dealer.

ever wondered what different types of Bluetooth earpieces there are

Bluetooth technology has been designed for many different purposes and situations. Consequently, when people want to buy a bluetooth ear piece for a specific situation, there are some things that they will need to consider. Specifically, based on their specific situation and circumstances, they will need to review the best style of bluetooth earpiece that is available on the market today. Since there are different styles that have been made for for one or more reasons, it's important for each individual to do their research to see which style can accommodate their needs. It is also important to note that the kind the person purchases must be comfortable so that they can wear them for an extended period of time and they fit the devices that they will be used for. Listed below are three of the bluetooth styles that’s currently offered by manufactures all over the United States and abroad.

Bluetooth ear pieces for Mobile Phones

Most people take their mobile phones wherever they go. To work, school, church, parties and all kinds of other events that they may attend. Because these phones have become commonplace in many environments, people have a need to handle them and talk to others when their hands are free. This is also a great reason for individuals who work in certain settings to make sure that they are buying the right style that will best fit their needs.

One specific style that some people may choose is the ear cradle style of headphone. In fact, this kind of bluetooth earpiece is idea for people who want to spend their time working out and performing all kinds of other extracurricular activities. People are also encouraged to buy this kind of style because they may be driving when they receive a telephone call from a family member. Or, they may be working at the job typing a memo or walking around taking care of wide hosts of other kinds of activities that are not conducive to holding a mobile phone by hand to the ear. Whatever the situation, this style of bluetooth earpiece technology is great for many different situations and purposes.

Bluetooth ear pieces and Headsets for Music Lovers

In addition to the cradle style for mobile phones, people should also review other styles as well. One specific style that is also functional in many different settings is the DJ over the head headphones. This style has been designed for the serious music lovers, especially those who can appreciate making distinctions in sounds and beats that come from specific musical instruments like the bass, violin, trumpet and other popular instruments. For those who like and prefer this kind, they will also find that this is one of the best styles for keeping out outside noises that normally interfere with a person’s overall entertainment experience. Also, because they are wireless, they are great for people who like to stay mobile during the day instead of remaining in a sedentary position.

Bluetooth Ear Pieces for IPODs

In some situations, people may want to use bluetooth technology with their IPODs. Therefore, they should consider buying an additional popular style bluetooth earpiece technology. This style is known to be very popular, specifically because it is similar to an actual earbud. An ear bud is also another excellent choice for people who want to remain both active and hassle free. Though this is a great choice for people who like to remain mobile in a wide variety of different situations, one of its main draw backs is that they tend to fall out of the individuals ear. Which means, they can also be lost since it lacks additional support to keep them stabilized inside the ear.

How 2 Way Radios Helped A Group Of Festival Volunteers Against Natures Fury

Entrusting security of a large bluegrass music festival to volunteers is an act of faith; handing us 2 way radio equipment gave us the power and connection to do the job right. For the price of a few day shifts and at least one overnight watch until sunrise, we security volunteers got to enjoy some of the finest concerts and classes in a beautiful mountain setting. When disaster struck -- twice -- we didn't need extensive training to be effective, just a fully charged battery.



First Challenge: Nice Guys Slide Off Dirt Roads

The first disaster was minor but challenging. A courteous pickup truck driver had moved over for oncoming traffic on a hillside dirt access road and slid off the edge just enough to get stuck. Calling for a tow was a perfect use of our radios that otherwise would have required sending a runner back down to the main tent. As the tow truck positioned itself to lift the truck back onto the road, we found a second radio use: solving problems by committee remotely!

Since no one outranked another, we wound up addressing the problem from several angles: "the road is blocked," said one, "halt the cars coming up." "I don't have authority to control traffic," said another. "There's no turning around, so they'll all be stuck if you don't," said the first. In the end, with quick radio communication instead of breathless runners doing a relay, a dead-end country traffic jam was avoided and the truck was rescued.

Second Challenge: Set Them Up and Blow Them Down

As if that wasn't excitement enough, on another festival day a mountain thunderstorm descended with hurricane-force winds. By the time the blow was over, camping and performance tents were scattered and destroyed, the entire area was drenched, and nearly every portable restroom was knocked over. The practical people running the event organized crews, called the restroom vendor, and went about setting everything right.

The festival proceeded with minimal interruption from the storm: the radios not only made recovery possible, but made getting back on track effective and timely. It's a good thing we had plenty of radios and volunteers to coordinate the activities. We got updated information to performers and attendees, and responded to issues requiring executive decisions or medical assistance as quickly as possible.

In addition to keeping the festival going, ensuring everyone's health and safety, and streamlining decision processes, using radio gave the festival a professional appearance with a large contingent of lightly trained volunteers. Event attendees could enjoy their week of mountain music and head home feeling that the organizers had great acts on stage and a team they could trust behind the scenes. Our teamwork contributed to a solid event reputation and growing attendance numbers year to year.

In a remote area where cell phone users had to find a good spot to get a connection, 2 way radios were the perfect solution for making festival volunteers efficient and effective. Bad luck and bad weather was no match for a dedicated crew that could work together over the airwaves. For the lonely overnight watchman role, the radio was a reassurance that he wasn't alone watching over the festival fans under the starry mountain sky.

Radio spectrum allocated for global flight tracking

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.”

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.”

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 .
