With a little simple meal planning, you can eliminate a great deal of stress from your daily life. There is nothing worse than getting to the end of the day and wondering what on earth you are going to feed a hungry family. So often we apply extraordinary precision and care to our jobs, to our kids' schedules or to our interest groups, but when it comes to the simple act of putting healthy, nutritious food on the table, we fail.
Our grandmothers knew how to manage a frugal, yet efficient and productive home -- and they didn't need expensive gadgets either! Many slow cookers sell in the range of to and the cost is soon easy beef stew made up by the thriftiness of eating at home.
So today I'm going to show you what I've been able to do with my brand new crock pot. I'm going to show you how I used it to make a week's worth of absol utely delicious sweet potato simple beef stew stew in just under 60 minutes.
Potluck meals can be fun, but an invitation to one can also include a certain level of anxiety. You may at first rack your brain on what to bring...your usual dip, vegetable casserole, or your world-famous chocolate chip cookies. Whatever you decide, you have a challenge that lies ahead of you: how do you make the same old dish exciting and new again? It's easier than you may think.
Ixnay on: Unwieldy Sandwiches. Instead of a big sandwich, I used to make two or three mini sandwiches on small potato rolls. They were easy to eat and you can vary the fillings. Your child also can scarf one down between classes if they are hungry (see also, "Mid-Morning Slump," below).
If you're planning on a really long emergency and are good at making your own food, you'll want to store things like buckets of wheat, flour, sugar, beans, salt, baking powder etc.
Furthermore, if you add some good bee f stock to your leftover slow cooker casserole, and throw in a little barley, you have the makings of a respectable Beef Barley Soup Recipe.
This Hartford, Ct area radio station regularly broadcasts contemporary country music, with a smattering of classic country songs thrown in the mix. Although Kix 97.9 broadcasts from the nearby Springfield, Massachusetts area, their signal is very strong in the Hartford, Ct area. The morning and afternoon drive- time shows on this radio station feature up- to- the- minute traffic reports and news bulletins. This radio station also offers many contests for listeners to perticipate in.

Camping Cooking Made Easy
Rice is something that you might usually make on the stove while making a stew or curry in the slow cooker. This is not always necessary though because it is possible to cook rice in the crockpot. Actually there are lots of grains you can slow cook, including millet and quinoa.
According to New Jersey monthly magazine, he originated from Leonia, New Jersey and now resides in Manhattan. He grew up eating at restaurants in both New Jersey and Manhattan. His parents loved food and they spent their summers in Barnegat Light on Long Beach Island. There Anthony became a lover of Jersey Shore food and local food from Bergen County. During my youth I spent much time in Bergen County, New Jersey and he mentioned several places where I also dined. He mentioned Hiram's in Palisade Park, where the hot dogs were to just die for, the Plaza Diner and Jerry's Italian Restaurant in Fort Lee for their spaghetti and swedish meatballs crockp ot. I must admit that it has been years since I have been to Fort Lee but all three of these places are still there when I do return.
Eat the way your ancestors ate. That means dropping all refined and processed products from your meal plans and go for simple things. Instead of refined starch eat salad. For a snack choose a carrot or some nuts over a baked muffin. Instead of processed meats such as sausage and salami go for the more natural form. Try a good steak or some homemade swedish meatballs.
Today Ikea stores make it possible slow cooker meatballs to furnish any home economically without having to sacrifice color style flair quality or comfort. With over 10,000 products available, the possibilities are not only endless but also impressive and inspirational. With a little creativity, a little cash and a few hours in an Ikea store, anyone can build an original living space on a budget.
A night work widow, I realized how dependent I'd become on popping a Stouffers into the nuke because cooking for one seemed pointless. No preparation, no dishes, no mess. When you cook, the floor gets dirty, the sink gets greasy, the dishes pile up -- and it takes time. So, what do you do while you wait for the chicken to bake, the veggies to steam and the rice to boil?
Pass down those family swedish meatballs egg noodles rachael ray and teach your children and grandchildren how to cook so they learn good dietary habits and the joy of cooking at the same time. Take time to prepare meals that not only provide memories, but help you last a long, healthy lifetime.

4 billion emergency radio system not yet proven
We have been very vocal against the new ESN network, Tetra is proven and works very well, the benefits to moving over to a 4G network are attractive, but will it stand-up to a major incident? Will the network be robust enough when there are thousands of communications in a located area? These concerns have now been picked up by a commons committee, read more below.
Aninquiry has revealed deep concerns about the coverage and contracting of a new 4 billion national emergency radio system.
A Commons Public Accounts Committeereportreleased this month criticised the Home Office for its handling of the proposed the Emergency Services Network, or ESN.
Plans to deploy the not yet proven emergency radio system by December 2019 would not be met, the committee said. The committee also criticised the Home Office for mishandling contracts talks for ESN and failing to plan for delays, that could cost nearly 500 million alone.
Good communications can make the difference between life and death for both emergency services personnel and the public but the technology ESN will rely on is not yet proven.
Across the UK, 105 ambulance, fire and police services are expected to switch from their existing Airwave Solutions radio system to ESN by December 2019.
Unlike the ageing Airwave network, ESN will operate on an existing retail 4G network rather than a dedicated emergency radio network.
However, the committee said forcing emergency services to share a network with the public had not been attempted at scale.
The approach relied on much improved network coverage across the UK, including on the London Underground, and new technology to prioritise emergency services over other network users.
Bringing together all the different elements to form an end-to-end system and scaling up these solutions and testing them adequately will be very challenging.
The government is expected to spend 1.2 billion developing ESN, 1.4 billion running down Airwave, and further 2.6 billion operating ESN until 2032.
The contract with Airwaves, which was bought by Motorola last year, expires in December 2019. The committee said extending this contract, which will almost certainly be necessary given expected delays, will cost an additional 475 million a year.
In 2015, Motorola and EE won the user services and networks contracts respectively for ESN.
The committee also criticised the Home Office for not maintaining competitive pressure while awarding the contracts and leaving the winning bidders in a very strong position when the contract comes up for renewal in 2023.
The committee recommended the Home Officer test the new network coverage rigorously, improve its tendering, budget and plan for an Airwave contract extension and reassess its timeline for switching to the new system.
It must take responsibility for convincing services to switch to ESN but also be clear at what point it will mandate the switchover.
The Home Office was told to report back to the committee by September this year.

We Have Listed 7 Different Communication Systems You Can Use At Your Event
There are many instances where people get confused when talking about types of headsets and the associated equipment. In this article, we are going to help you get a clear understanding of the different types of headsets and the associated equipment. With that said, it is important to note that the names that have been given below, are the actual names that need to be used. Without any further ado, lets get started;
In Ear Monitors
Also known as in-ear (or canal) headphones, these devices sit inside the user's ear canal, and they deliver great sound quality; they ensure a controlled and precise sound. They also fill the ear's entrance, thus are very effective at sealing out any unwanted external noise. These devices include a transmitter which is controlled by an audio engineer which then transmits to the belt-pack on the user. The in ear monitors allow freedom of movement and are commonly used by modern pop a rtists. They're very small and allow them to comfortably hear the rest of the band, and also themselves (this is what's known as monitoring or foldback). Apart from artists, these devices are commonly used by audio engineers to hear the mix of the vocals and the stage instrumentation for recording studio mixing and/or live performance.
2 Way Radio Headsets
Two way radio headset is a communication device which can transmit and also receive signals. A two way radio headset allows the user to communicate with other people with similar 2 way radio headsets (and are operating on the same channel or radio frequency). Two way radio headsets are readily available in mobile and also hand held portable configurations. The handheld 2 way radio headsets are also known as walkie talkie headsets or handie talkies. One thing to note about two way radio headsets, is that the user can either transmit or receive signals and not both at the same time.
2 Way Radio Covert Pieces
These are quite similar to the Two way radios, however, they are much more discreet. 2 way radio covert earpieces are usually used by security personnel as they prefer staying discreet. This type of walkie talkie headset is also ideal for the Door supervisors and security staff.
Wired Show Comms
Unlike Two way radios, these type of communication systems allow for both talking and listening even at the same time. These devices have a closed cup design, meaning they fully cover the ear which helps reduce the ambient noise. Wired show comms come in single muff and double muff versions. They get attached to the belt pack controller which is then physically wired to the system. Because of the cabling that's involved in wired show comms, there's less mobility thus are best suited for managers and the static technicians. These specialist communication dev ices are also commonly used for calling shows.
Wireless Show Comms
These are very similar to the wired Show Comms, only difference is that their belt packs are wireless. The device and the belt pack are compatible which means that the users can freely and comfortably move around, thus are ideal for stage managers, front of house managers, among others. Just like the wired show comms, these devices also allow both talking and listening at the same. With that said, you should know that the wireless show comms are relatively more expensive than the wired show comms. Some of the other applications for these devices include, but not limited to; security personnel, broadcast, marines, theater, and colleges. They can also serve as convenient walkie talkie headset for events.
Radio Performer Headset
This is the device that's used by presenters and performers. This device allows for the user's voice to get fed into the sound system where the audience can get to hear them. This device is usually used in conjunction with the radio belt pack system. Most of the devices used today are generally very thin and skin colored which helps reduce visibility when the performer is on stage.
Presenter Talkback
These are the small ear pieces which you see the lead presenters on TV talk shows wearing. This device allows the producer (of that particular TV talkshow or program), to communicate to the lead presenter and update them on the show's progress. This may be done using a system known as in ear monitoring. Alternatively, wi reless show comms systems can also be used.

Software Defined Radio (SDR) Market Forecast By End-use Industry 2014-2020
We are seeing a monumental movement in the radio communication industry, as this very technical article shows the transition from hardware to software within the radio communication industry is just around the corner. With 3G and 4G providing Data and Voice Comms covering large distances, RF communication will find it hard to compete, the simple answer seems to be Tetra, but is that long term? There will always be a need for point to point communications, but larger comms infrastructures could possibly be managed in a different way.
With the evolution of digital electronics the radio market and communication technologies have evolved a lot. Though the concept of software defined radio (SDR) is not new, in the recent years, this market has undergone many changes in terms of technology and uses. SDR is a type of radio communication system where communication is carried out by the use of software on embedded system or personal computer instead of implementing hardware such as filters, amplifiers, mixers, detectors, demodulators and modulators, among others. SDR are capable of transmitting and receiving a wide spectrum of frequency. When the data from a source is converted into digital format, the remaining activities involved in radio communications are carried out with the help of software driven automated functions.
SDR optimizes the tactical information system as embedded software used in SDR helps in the dynamic selection of the communication channel. The number of digital service users is increasing resulting into the improved adoption rate of software defined radio. Public safety, military and commercial use are the three major end-use applications of SDR systems. The demand for SDRs in expected to increase in coming years owing to efficiency and cost effectiveness offered by them. The industry has undergone t ransformation from analog to digital. Thus, the advance capabilities of digital radio are expected to drive the growth of SDR market. Multiple regulations govern the SDR market and this affects the market growth and trends. For instance, the Federal Communications Commission (FCC) legally created a newer class for equipment of SDRs that had streamlined equipment authorization procedure.
Military modernization programs being carried out by several countries such as South Korea, India, Germany, Japan and the U.S and the interoperability provided by SDR are major driving forces for SDR market. The issues faced in the integration of the various sub systems pose a challenge to the SDR market. Further, the development of software platforms, technologies and tools, which allow flexible specification, design and implementation of radio systems, is another significant challenge. Players in software defined radio market have potential opportunity in technical advancements of SDR techn ology such as resolving the problem of frequency congestion, wide frequency range (spectrum) and improved broadcasting services in future.
Software defined radio market is segmented on the basis of type, end-user application and geography. On the basis of type of SDR, the market is segmented into ideal software defined radio, baseband software defined radio (BBSDR) and high frequency software defined radio (HFSDR). On the basis of end-user industry, SDR market is segmented into defense industry, telecom industry, manufacturing plants, public safety vendors and personal use. U.S. Canada, Japan, France, Brazil, South Korea, India, Germany and Italy have emerged as the leading countries for software defined radio market.
Some of the key vendors in software defined radio market are BAE Systems PLC, Elbit Systems Ltd., IndraSistemas, L3 Communications Corporation, Raytheon Co ., Rohde & Schwarz GmbH & Co KG, Thales Group, Viasat Incorporated, SAAB AB, Rockwell Collins, Northrop Grumman Corp., ITT Corporation, Harris Corporation and Datasoft Corporation, among others.
This research report presents a comprehensive assessment of the market and contains thoughtful insights, facts, historical data and statistically-supported and industry-validated market data and projections with a suitable set of assumptions and methodology. It provides analysis and information by categories such as market segments, regions, product type and distribution channels.

Offering workers hearing protection options
Much Like Protecting your sight or looking after your health, your hearing should also be protected, this article tackles hearing protection within the workplace and what type of earplugs are best, Enjoy.
OSHA regulations dictate we offer a “variety†of hearing protectors to noise-exposed workers. What is best practice for providing a variety while keeping inventory to a minimum?
Per CFR 1910.95(i)(3), “Employees shall be given the opportunity to select their hearing protectors from a variety of suitable hearing protectors provided by the employer.†But does “variety of suitable hearing protectors†mean two or 10, earplugs or earmuffs, different colors or different sizes?
The wrong approach is to choose a variety based on factors that have no effect on protecting hearing, including the published noise reduction rating. Some safet y managers offer several different large foam earplugs that are yellow, green and orange â€" mistakenly assuming they meet the “variety†requirement and not realizing that a significant portion of their workforce will never achieve an adequate fit with a large foam earplug. In those cases, their supposed “variety†actually limits the number of workers adequately protected.
This bad assumption is often codified into company safety policies that require a minimum NRR: “Approved hearing protectors must have an NRR of at least 32 decibels,†or similar criteria. By definition, that typically means a large foam earplug. Despite the higher NRR based on 10 laboratory test subjects, workers with smaller ear canals will never achieve an adequate fit with those large foam earplugs to stop noise-induced hearing loss.
What are the factors that affect good fit of an earplug?
Based on thousands of fit tests administered to workers in the field, the following four earplug styles provide a selection that would adequately protect nearly every worker:
The good news is that offering a variety does not necessarily increase cost. Buying 1,000 earplugs of one style or 250 earplugs of four different styles is fairly equivalent in cost. But the bigger variety significantly increases the probability that more workers will be adequately protected.
Many worksites adjust their inventory based on results of their fit-testing of hearing protectors. By reviewing which earplugs repeatedly provide the best fit, these companies identify the gaps or duplications in their offering and can adjust accordingly. Sometimes, this means adding a smaller-size earplug, but many times companies find they can remove some less-effective earplugs from their inventory. It’s not necessary to carry a dozen different earplug styles.
Finally, any offering of hearing prote ction needs a hands-on training component. How can a workers determine whether their ear canal is large or small, round or oval? It’s impossible to view your own ear canal opening in a mirror. A quick glance by a safety trainer can be of tremendous benefit in helping workers select the right earplug the first time.

- Size:Â Like a cork in a bottle, an earplug that is to o large or too small will never achieve an acoustic seal to protect hearing. Offering a variety of sizes significantly improves the percentage of employees obtaining a good fit.
- Shape:Â Ear canal openings may appear round, oval or slit. A foam earplug often fills an oval or slit opening better than pre-molded earplugs.
- Ease of insertion:Â Some workers have difficulty rolling or inserting foam earplugs due to lack of mobility. For these workers, an earplug with a stem may be easier to insert.
Based on thousands of fit tests administered to workers in the field, the following four earplug styles provide a selection that would adequately protect nearly every worker:
- Large foam earplug
- Smaller foam earplug
- Large reusable earplug
- Smaller reusable earplug
The good news is that offering a variety does not necessarily increase cost. Buying 1,000 earplugs of one style or 250 earplugs of four different styles is fairly equivalent in cost. But the bigger variety significantly increases the probability that more workers will be adequately protected.
Many worksites adjust their inventory based on results of their fit-testing of hearing protectors. By reviewing which earplugs repeatedly provide the best fit, these companies identify the gaps or duplications in their offering and can adjust accordingly. Sometimes, this means adding a smaller-size earplug, but many times companies find they can remove some less-effective earplugs from their inventory. It’s not necessary to carry a dozen different earplug styles.
Finally, any offering of hearing prote ction needs a hands-on training component. How can a workers determine whether their ear canal is large or small, round or oval? It’s impossible to view your own ear canal opening in a mirror. A quick glance by a safety trainer can be of tremendous benefit in helping workers select the right earplug the first time.

MIT's new method of radio transmission could one day make wireless VR a reality
VR is the Buzz word for this year, every technology company clambering to get their headset out on to the market. Much of the market needs to catch-up though, the power of home computing needs to improve and removing the inevitable extra cabling and wires that come with current headsets. Luckily this article is about the future technology of VR headsets, see what we can expect as this technology grows.
If you want to use one of today's major VR headsets, whether the Oculus Rift, the HTC Vive, or the PS VR, you have to accept the fact that there will be an illusion-shattering cable that tethers you to the small supercomputer that's powering your virtual world.
But researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) may have a solution in MoVr, a wireless virtual reality system. Instead of using Wi-Fi or Bluetooth to transmit data, the research team’s MoVR system uses high-frequency millimeter wave radio to stream data from a computer to a headset wirelessly at dramatically faster speeds than traditional technology.
There have been a variety of approaches to solving this problem already. Smartphone-based headsets such as Google's Daydream View and Samsung's Gear VR allow for untethered VR by simply offloading the computational work directly to a phone inside the headset. Or the entire idea of VR backpacks, which allow for a more mobile VR experience by building a computer that's more easily carried. But there are still a lot of limitations to either of these solutions.
THE MOVR PROTOTYPE SIDESTEPS TETHERED VR ISSUES
Latency is the whole reason a wireless solution hasn't worked so far. VR is especially latency-sensitive, along with the huge bandwidth requirements that VR needs to display the level of high-resolution video required for virtual reality to work. But the MIT team claims that the millimeter wave signals can transmit fast enough to make a wireless VR headset feasible.
The issue with using millimeter wave technology is that the signal needs a direct line of sight, and fares poorly when it encounters any obstacles. MoVR gets around this by working as a programmable mirror that can direct the direction of the signal to the headset even while it’s moving to always make sure the signal is transmitting directly to the headset's receivers.
For now, the MoVR is simply a prototype, with the team hoping to further sh rink down the system to allow for multiple wireless headsets in one room without encountering signal interference. But even as a proof-of-concept, it's an interesting perspective on how virtual reality could one day work.

Three Styles Of Security Earpieces With Mics
If you are looking for a security earpiece with a mic, then you will need to know the varieties available out there. While some types are more expensive than others, what ultimately matters is the quality and durability of what you get at the end. Below is a look at what you get out there:
One wire kit
With this one, there is only a single wire, which emerges from the radio, runs through the PTT and then ends where the earpiece starts. This makes for a simple yet effective look. As for the length of the cable, the one wire kit has a piece that runs between 28 and 34 inches. This means that you have at your disposal a length sufficient to cover the distance between your ears and the waist without any kind of stretching or straining. Of course, the reach of every security earpiece will be determined by the height of the person wearing it . The one wire kit is great for an average height and will work for anyone 6 feet and below.
Most one wire kits come in the original D and G shapes. There are some fancier designs out there as well if that’s what you are looking for.
Two wire kits
As the name suggests, there are two wires involved in this scenario. One runs to the Push to Talk (PTT) button. The other runs up to the earpiece, making for a good looking dual connection. For the purposes of discretion, you are allowed to wear this cable partially disguised within your clothing. One wire will emerge from the radio, rising up your back to the ear in a way that keeps you comfortable. The other cable runs from the radio, up the length of your hands and terminates at the cuffs if you are wearing a lo ng-sleeved shirt or sweater. In terms of length, the two-wire kit is essentially the same as its one wire counterpart, with a reach of 30 to 34 inches. This accounts strictly for the length of each individual wire, and allows the unit to comfortably cover the areas between your waist and the ears. Two wire kits commonly come in the form of an acoustic tube that many who know a little about surveillance will be able to understand.
3 Wire kits
Here, you have three wires coming off the radio. The first wire will terminate where the earpiece is built. The second will end where the Push to Talk button is located. The last will end at a connection with the mic. As with the two wire kits, this one is worn under ordinary clothing, with a cable for the mic, earpiece and PTT button. There is really no standard length for all the three wires and there is no guarantee that all of them will be equal in length, but there is a sense of flexibility in the way you get to use the piec e. Always try on sample pieces before making a purchase at a store. Over the internet purchases are trickier but then the measurements will be highlighted long before you order.
Understanding the functionality of PTT technology
Push to Talk is a cutting-edge technology that allows for direct communication between parties at agreed-upon frequencies and distances. The greatest thing about PTT is that it switches communications from duplex to half duplex. This means people do not talk over each other but get to alternate between speaking and listening. PTT is able to loop in two or more speakers at an instance of communication, allowing for conference-like types of engagements between participants. This streamlines communication. Most enterprises prefer this approach to communication because there are no limitations in terms of allotted minutes. A s such, there is absolutely no need to stay within the confines of a data plan, which would be both expensive, inconvenient and rigid.
There is no such thing as a right security earpiece. What works for you may not work for all other parties across the board. While your budget matters a lot, you are looking for something that works optimally and stands the test of time. The three types mentioned above are alright if you are looking for something that works all the time. Remember, prices will vary across brands and models.

NFL investigating Giants for using two-way radio during game against Cowboys
Apparently using a two way radio during an American football game is frowned upon over in the good old US of A, This article is about a game between the Giants and the Cowboys. During a Game the coaching staff and Quarterback are not allowed to communicate if there is 15 seconds or less on the clock, this rule might have been broken with the use of a walkie talkie.
The NFL is investigating the Giants’ potentially rule-breaking use of a two-way radio during the team’s recent 10-7 win over the Dallas Cowboys.
The use of a two-way radio by a coach during a game is strictly against league rules, according to ESPN.
In the fourth quarter of the game, Giants head coach Ben McAdoo was spotted using a walkie-talkie to communicate play calls with Eli Manning after his headset malfunctioned.
The Cowboys issued a formal complaint to the league over the radio use, but the NFL’s investigation was already underway by the time Dallas contacted them.
The NFL has a rule against coaches using two-way handheld radios because the league cannot control when both parties are communicating.
A coach using a walkie-talkie makes it harder for the NFL to monitor a league rule that states communication from the sideline to the quarterback must end when 15 seconds are left on the play clock.
With headsets, the NFL has the power to shut off communication at will with a “cutoff switch operator,†ESPN reported.
The Giants had no comment when reached Thursday night.
McAdoo used the walkie talkie in question, however, for about four or five plays on the Giants’ fourth-quarter drive that ended in an Eli Manning interception on a pass intended for Victor Cruz.
McAdoo’s normal equipment malfunctioned and as the Giants worked to fix it, the coach was handed the walkie talkie temporarily because its signal was reaching Manning’s helmet.
As the Giants worked to correct McAdoo’s equipment, Odell Beckham Jr. could be seen running to the sideline to bring plays back to the huddle and Manning was heading over to the sideline, as well.
There is no evidence in reviewing the game film that demonstrates McAdoo was on the walkie talkie for longer than the allowed 15 seconds of communication with his quarterback.
There is also, of course, no evidence that the Giants gained any advantage even if he was. The drive ended in a turnover and the Giants’ offense stunk most of the night.

Ham radio: A last resort when phone lines fail
We at this blog believe in radio communications and will never let it die, understanding the importance that it still plays, and during the worst catastrophes, will be the best form of communication. This story about 9-11 adds proof to this statement.
If disaster strikes, there is a form of communication that can still get through: a ham radio.
When 9/11 hit New York City in 2001, for instance, ham radio operators provided a connection to the outside world.
One of those people was amateur radio enthusiast Bob Kyvig, formerly of White Bear Lake, who now lives in Centerville.
“The only communication out there on 9/11 was amateur radio,†Kyvig recalled. “The telephone lines were jammed and no one was going in or out.â€
On the days following that horrific attack, Kyvig assumed the role of messenger, relaying messages from Manhattan to loved ones in the area by calling or knocking on their door. His house calls would go like this: “I am Bob; I am a ham operator. I just communicated with your loved one; they are fine and doing well and they will talk to you soon.â€
When White Bear Lake sailor Gerry Spiess landed in Samoa on his historic solo voyage across the Pacific Ocean in 1981, he contacted Kyvig, who connected Spiess with his wife Sally.
When Hugo’s tornado struck in 2008, he and wife Jill remained on the radio as long as they could but had to abandon the “ham shack†as the storm approached. The tornado did $30,000 damage to their home, including Kyvig’s outside antennas.
A ham since 1968, long before Facetime, email or Skype, Kyvig was 20 when he took up the hobby while serving in the Navy. He was stationed in Hawaii and had childhood buddies serving in Germany and aboard the USS Milwaukee. The three met on the radio at least once a week without fail for more than 40 years, until the death of one of the men in 2015.
That connection to people is what Kyvig most enjoys. He chats on the radio to people he’s never met around the world.
“It’s a worldwide network of people enjoying fellowship with other hams,†Kyvig said.
The radio operator answers calls for help in areas of “health and welfare,†and was on Centerville’s first CERT (citizen emergency response team), which is now inactive. He serves as a severe weather spotter too, and gains “insights†as to what is happening around the world by chatting to foreigners.
“We talk about everything from fishing, to weather and local problems,†he said. “It’s very interesting because you find out so much about people across the world. And it’s not just the personal part but handling messages for help in disasters.â€
He’s listened to astronauts aboard the space station and scientists at the South Pole. He has talked to people in Russia, New Zealand and most of Europe. For a long time, he kept a conversation going with a man in Norway who lived close to some of his relatives. Wife Jill also has her ham license and enjoys talking to other women, known as YLs or young ladies, across the world. “Lord knows what they’re talking about,†Bob said. “I leave the room.â€
Ham buffs do have opportunity to meet at events called “eyeball picnics.†The Kyvigs traveled to a picnic in Branson, Missouri earlier this summer to socialize with other hams and match voices with faces.
Without getting too technical, Kyvig explained that radio signals are bounced up through the ionosphere. The signal goes up and down several times before it hits the final destination and you don’t control where it hits. People who want to contact Kyvig can tune into his call number: WA0ROH, assigned by the Federal Communications Commission (FCC), which regulates interstate and international communications. The agency requires operators to keep a log of who they talk to on an electronic spreadsheet.
“We could be talking to people the FCC thinks is a bad guy,†he said. “Because we can transmit all over the world without a phone line, some use it to their own means.â€
Other countries have comparable agencies.
Each country has its own beginning call letters. The United States uses W, K and N.
“The concept is simple,†he added. “We use what Mother Nature has provided: airwaves. We plug a number in for a country and anyone can answer.â€
A true party line, Kyvig said 30,000 people could be listening in on a conversation.
Jill proudly pointed out that Bob earned a master’s degree from The 3905 Century Club. It’s not the typical academic degree, but a difficult achievement nonetheless. “The degree was a challenge,†he said, which explains why only 68 radio operators have received the degree since 1967.
Bob inspired her to get her license, Jill said, and together they do public service events using ham radio.
Invented in the early ’20s, ham equipment is evolving, but affordable. Newbies can do it for about $300, he said. There are antennas on his roof, but mostly they are horizontal wires stretched between a tree and the house. Generator backup is used if there’s a power outage. He also keeps a mobile 12 volt transmitter that he can use in his truck to chat while he’s driving.
At one time, working knowledge of Morse code was a requirement to get an FCC ham license, but that was dropped, so more people are getting into it, he said.
When he’s not on the radio, Kyvig enjoys making furniture and fixing TVs. He retired from a career in computer operations about five years ago.

What Every Headset Purchaser Should Know
Closed Back Headphones vs. Open-back Headphones
Open-back headphones have pads which rest on the outer ear. They're designed such that the outer shell of the ear cup has perforations usually with horizontal cutouts. The Open back headphones design of the ear cup enhances better natural sound because of less coloration as compared to the Closed back headphones.
Closed back headphones have much larger earpads which encircle the ears. They are designed such that there's a big pad which cups the ears, and it features an insulated outer shell of plastic which covers the ears. The Closed back headphones actually have a very solid outer shell which doesn't have any sort of perforations such that the outer shell effectively cups/encircles the entire ear. The Closed back headphones are excellent at isolating noise. They block most of the ambient noise, but they've a smaller sound stage, which gives the user the perception that the audio/sound is originating from within their head. Closed back headphones also tend to produce much stronger low frequencies as compared to Open back headphones.
Low Impedance vs High Impedance
Headphones normally come in various different impedance levels, such as 8 ohms, 16 ohms and 32 ohms. The power that's supplied by an audio source may be at varying levels because of a variety of factors including being limited because of being battery powered. Generally, as the impedance of the headphones increases, much more voltage will be required in order to drive it, and the audio loudness of headphones for a particular voltage decreases.
The determination of impedance is usually disregarded by many headphone buyers, however, the truth is it's one of the most important factors to consider when choosing the best headphones for your particular needs. Impedance is basically just how much power the headphones can put out so that it can overcome resistance to move the headphones' diaphragm.
Low impedance headphones (that is, less than 25 ohm), usually require little power in order to deliver high audio levels. Low Impedance headphones play well with devices which have weak amplification. These can include; mobile phones, portable music players and various other portable devices. This type of headphones can be used at home and also while jogging with your mobile phone; this is one of the reasons why most of the on-, in-, and over the ear headphones, are low impedance. Low impedance headphones are normally designed to get plugged directly in to a single (one) source, and generates sound more efficiently from a lower level input signal. This headphones tend to be much louder and much more efficient, however, they will also require a much more capable amplifier.
High impedance headphones (25 ohms and above), generally require more power in order to deliver high audio levels. As a result, they're protected from damages caused by overloading. High impedance headphones are typically designed for studio like applications where there might be multiple phones/devices wired in parallel and receiving input signals from a single source. High impedance headphones are more tolerant of the amplifier limitations, however, they will produce less volume for a particular output level. They are also a little more durable (that is, electronically), however, they require much higher signal levels in order to produce the same level of output level of the low impedance headphones. This type of headphones can be used with a wider range of audio equipment.
Passive Headphones vs. Active Headphones
Passive (noise cancelling) headphones are made of materials which help in blocking out sound waves from the surrounding environment. The same way ear muffs soften the outside noise, so does this type of headphones employ passive noise canceling. This type of headphones are typically used for both professional mixing and monitoring, like in broadcast and recording studios, and such other applications. Passive headphones are basically designed to playback music/audio true to the actual original recording, with minimal, compression, EQ, and such other sound enhancements.
On the other hand, Active headphones use batteries in order to power the built in Digital Signal Processing (also abbreviated as DSP) technology which processes play back for a particular reason, for example, to enhance the bass and the high end. Due to the enhancement of playbacks with sharper high ends and more bass, active headphones are more popular for general listening and listening to music for pleasure. Active noise cancelling headphones are also made of materials which help in blocking out outside noise, however, they take things a step further by making their very own sound waves; the sound waves created mimic the outside noises, but are a mirror image of each other, thus cancels each other out.
Wired Headphones Vs Wireless Headphones
When choosing a pair of headphones, deciding between wireless vs. wired is among one of the most overlooked factors. Wireless headphones might be a more popular choice, however, the wired headphones also have their own set of benefits. Well, that being said, as a general rule of thumb, between wireless headphones and wired headphones, assuming a similar price between the models; the wired headphones usually offer a much better quality. Also, the audio quality may get compromised over Bluetooth.
You can opt for the wireless headphones if you are not much of an audiophile, and you tend to travel a lot. If you really don't like getting the cables of your headphones getting tangled, or caught while listening to music/audio, then the choice should be rather simple; go for wireless headphones.
You can opt for the wired headphones if you are an audiophile, and you do not necessarily bother with the wireless options unless absolutely essential like using them when traveling, or keeping the headphones as a backup. As aforementioned, the wired headphones are way ahead in terms of output quality as compared to the wireless headphones. You will never have to worry about running out of batteries, unless you happen to opt for wired headphones which cancel noise. In addition, you will never suffer from interference from the other commonly used wireless electronic devices. However, you will need to take good care of the wired headphone cables, or they will eventually break.
Open-back headphones have pads which rest on the outer ear. They're designed such that the outer shell of the ear cup has perforations usually with horizontal cutouts. The Open back headphones design of the ear cup enhances better natural sound because of less coloration as compared to the Closed back headphones.
Closed back headphones have much larger earpads which encircle the ears. They are designed such that there's a big pad which cups the ears, and it features an insulated outer shell of plastic which covers the ears. The Closed back headphones actually have a very solid outer shell which doesn't have any sort of perforations such that the outer shell effectively cups/encircles the entire ear. The Closed back headphones are excellent at isolating noise. They block most of the ambient noise, but they've a smaller sound stage, which gives the user the perception that the audio/sound is originating from within their head. Closed back headphones also tend to produce much stronger low frequencies as compared to Open back headphones.
Low Impedance vs High Impedance
Headphones normally come in various different impedance levels, such as 8 ohms, 16 ohms and 32 ohms. The power that's supplied by an audio source may be at varying levels because of a variety of factors including being limited because of being battery powered. Generally, as the impedance of the headphones increases, much more voltage will be required in order to drive it, and the audio loudness of headphones for a particular voltage decreases.
The determination of impedance is usually disregarded by many headphone buyers, however, the truth is it's one of the most important factors to consider when choosing the best headphones for your particular needs. Impedance is basically just how much power the headphones can put out so that it can overcome resistance to move the headphones' diaphragm.
Low impedance headphones (that is, less than 25 ohm), usually require little power in order to deliver high audio levels. Low Impedance headphones play well with devices which have weak amplification. These can include; mobile phones, portable music players and various other portable devices. This type of headphones can be used at home and also while jogging with your mobile phone; this is one of the reasons why most of the on-, in-, and over the ear headphones, are low impedance. Low impedance headphones are normally designed to get plugged directly in to a single (one) source, and generates sound more efficiently from a lower level input signal. This headphones tend to be much louder and much more efficient, however, they will also require a much more capable amplifier.
High impedance headphones (25 ohms and above), generally require more power in order to deliver high audio levels. As a result, they're protected from damages caused by overloading. High impedance headphones are typically designed for studio like applications where there might be multiple phones/devices wired in parallel and receiving input signals from a single source. High impedance headphones are more tolerant of the amplifier limitations, however, they will produce less volume for a particular output level. They are also a little more durable (that is, electronically), however, they require much higher signal levels in order to produce the same level of output level of the low impedance headphones. This type of headphones can be used with a wider range of audio equipment.
Passive Headphones vs. Active Headphones
Passive (noise cancelling) headphones are made of materials which help in blocking out sound waves from the surrounding environment. The same way ear muffs soften the outside noise, so does this type of headphones employ passive noise canceling. This type of headphones are typically used for both professional mixing and monitoring, like in broadcast and recording studios, and such other applications. Passive headphones are basically designed to playback music/audio true to the actual original recording, with minimal, compression, EQ, and such other sound enhancements.
On the other hand, Active headphones use batteries in order to power the built in Digital Signal Processing (also abbreviated as DSP) technology which processes play back for a particular reason, for example, to enhance the bass and the high end. Due to the enhancement of playbacks with sharper high ends and more bass, active headphones are more popular for general listening and listening to music for pleasure. Active noise cancelling headphones are also made of materials which help in blocking out outside noise, however, they take things a step further by making their very own sound waves; the sound waves created mimic the outside noises, but are a mirror image of each other, thus cancels each other out.
Wired Headphones Vs Wireless Headphones
When choosing a pair of headphones, deciding between wireless vs. wired is among one of the most overlooked factors. Wireless headphones might be a more popular choice, however, the wired headphones also have their own set of benefits. Well, that being said, as a general rule of thumb, between wireless headphones and wired headphones, assuming a similar price between the models; the wired headphones usually offer a much better quality. Also, the audio quality may get compromised over Bluetooth.
You can opt for the wireless headphones if you are not much of an audiophile, and you tend to travel a lot. If you really don't like getting the cables of your headphones getting tangled, or caught while listening to music/audio, then the choice should be rather simple; go for wireless headphones.
You can opt for the wired headphones if you are an audiophile, and you do not necessarily bother with the wireless options unless absolutely essential like using them when traveling, or keeping the headphones as a backup. As aforementioned, the wired headphones are way ahead in terms of output quality as compared to the wireless headphones. You will never have to worry about running out of batteries, unless you happen to opt for wired headphones which cancel noise. In addition, you will never suffer from interference from the other commonly used wireless electronic devices. However, you will need to take good care of the wired headphone cables, or they will eventually break.

Ericsson first to deliver 5G NR radio
We are seeing a new era in communications at the moment, the move from tetra and RF to the mobile network. The uk’s emergency services will be moved over to EE’s ESN system slowly until 2020 using Motorola kit designed particularly for the technology. The natural evolution is 5G, which we won’t see for many years, but Ericsson have taken the baton and are running with it.
Ericsson (NASDAQ:ERIC) is commercializing the world's first 5G NR radio for massive MIMO, with the first deployments coming in 2017. Together with the Ericsson 5G Plug-Ins announced in June and Ericsson's already commercially available Radio System Baseband 5216, which currently powers Ericsson's award-winning Radio Test Bed, Ericsson is first to deliver all components of a 5G access network.
Tom Keathley, senior vice president, Wireless Network Architecture and Design, AT&T, says: "As we accelerate toward 5G, it's beneficial to have a flexible radio platform that can be deployed not only for LTE, but also versions of future 5G NR standards."
AIR 6468 combines advanced antennas with a large number of steerable ports to enable 5G technologies of beamforming, Massive MIMO and -- building on that -- Multi-user MIMO, initialized as MU-MIMO. These capabilities improve user experience while enhancing the capacity and coverage of the network and reducing interference. The new radio provides LTE support as well, so it is applicable in today's networks.
Huang Yuhong, Deputy Head, China Mobile Research Institute (CMRI), says: "Massive-MIMO, also known as 3D MIMO, is an important milestone in China Mobile's technology roadmap from 4G to 5G. We are very happy that Ericsson's new radio product is coming to market soon to meet our needs and enable us to integrate 5G technologies into our existing networks."
A host of new additions to the Ericsson Radio System are also coming that address key 5G requirements, in today's networks.
Daniel Staub, Head of Joint Mobile Group, Swisscom, says: "On the road to 5G, we will continue to invest in LTE advancements that will become part of our 5G networks. For us, it is key that Ericsson has chosen to focus on advances that will support us in this evolution. These enhancements will further improve the customer experience."
Additional new Ericsson Radio System gear addresses 5G concepts
Peter Jarich, Vice President, Consumer and Infrastructure Services, Current Analysis, says: "Mobile operators, today, are clearly focused on the race to 5G commercialization, while also continuing to invest in their existing LTE networks. With a new 5G radio and LTE offerings which echo key 5G concepts - small cells, licensed-unlicensed band combinations, Cloud RAN, network densification, spectrum optimization - Ericsson's new portfolio additions and Ericsson Radio System innovations provide a compelling way forward."
To support new network builds, Ericsson has created the industry's first Industrialized Network Rollout Services solution. The Network Deployment Delivery Platform coupled with Ericsson's pioneering process facilitates the complete configuration, installation, integration, shakedown and handover of a fully verified site, ready in a single site visit.
Arun Bansal, Head of Business Unit Network Products, Ericsson, says: "Ericsson has driven innovation in every generation of mobile technology and now we are set to over-deliver on an aggressive promise. We are introducing the new hardware that 5G Plug-Ins, announced in June, will run on, so that the first operators can start to deploy 5G infrastructure. And, we are also launching innovations that improve both the performance and efficiency of today's networks using concepts that will evolve into 5G."

Hytera Awarded Multi Million Dollar Contracts in Dominican Republic
Hytera are the fastest growing radio country this year, they have opened offices all over the world and are taking market share from Motorola. When you look at their Hytera earpieces, Chargers, repeaters, hand portables and base units they are of an excellent standard and quality. That is probably why the Dominican Republic was persuaded to use them for two big projects.
Hytera, a world leading solution provider of Professional Mobile Radio communications, was awarded two projects by the Ministry of the Presidency of Dominican Republic. In order to establish a nationwide emergency response network for National Emergency Care System and Security 9-1-1 (Sistema Nacional de Atención a Emergencias y Seguridad), Dominican Republic government selected TETRA (Terrestrial Trunked Radio) technology for mission critical communications, and launched two public tenders at the end of 2015; one is to cover two cities, Haina and San Cristobal, adjacent to the capital city Santo Domingo, with 5 sites and 528 terminals, while the other is to cover Santiago, the second largest city of the country, with 30 sites and 2,155 terminals.
The existing TETRA network in the Santo Domingo area was delivered also by Hytera as a result of a contract awarded by Dominican Republic's Ministry of the Presidency in 2013. The project includes several components: the 911 system, a camera surveillance system and the communications infrastructure with its respective terminals which was awarded to Hytera. “The system in Santo Domingo offers reliable communication services to the public safety forces, and it is a very good testimony of Hytera’s solutions and supports,†said Fernando Camelo, regional director of Hytera international business.
“Dominican Republic government officials have spent a lot effort to choose the right technologies for its public safety forces. Obviously, TETRA has been widely adopted and proved. We are proud to be part of the initiative of building a united nationwide mission critical communication system for the country,†commented Ming Kam Wong, deputy general manager of Hytera international business.
The TETRA digital standard as a global open protocol provides secure, encrypted communications for mission critical operations as well as promoting a more efficient use of spectrum. More than 750 interoperability (IOP) certificates have been awarded to more than two dozen manufacturers by the TETRA + Critical Communications Association (TCCA), the governing body, globally, for the TETRA standard.

What Is A Two Way Radio Earpiece
A two way radio is a type of communication that can both receive and transmit information. The radio enables the operators to have conversations with other similar radios operating under the same (channel) frequency. Two way radios are available in stationary base, hand-held portable and mobile configurations. Often, hand-held radios are called handie-talkies, or just walkie-talkies.
Two way radio systems normally operate in a half-duplex mode, in which the operator can listen, or he can talk, though not at the same time. A “Press To transmit†or “push-to-talk†PTT button initiates the transmitter when released, hence activating the receiver. A cellular telephone or mobile phone is an example of a two way radio that both receives and transmits at the same time (full-duplex mode).
Full-duplex is usually achieved through frequency-sharing methods or by using two different frequencies to simultaneously carry the 2 directions of the conversation. Dynamic solid state filters and use of two antennas are some of the methods used for mitigating the self-interference caused by simultaneous same frequency reception and transmission.
Types of two way radio earpiece
Two way radio earpieces come in a variety of types. They include: D ring, acoustic tube and ear hook. The acoustic tube type features a wireless transceiver operating in a radio-frequency band that receives audio signals. It has an acoustic chamber and an acoustic transducer, which is coupled electrically to the transceiver, and operates to activate acoustic signals.
Connectors
As far as covertness is concerned, communication must definitely be very discreet, whether it’s a just a private group or a security personnel of designated people. Two-way radios are used for conversations between compatible devices in a given location. Nonetheless, it would be much less comfortable if somebody talks through the radio and the entire communication is disrupted.
That’s why there are different types of two way radios connectors in the world, and they include Motorola, Hytera, Icom, and Kenwood, among others. Motorola is the leading connector of two way radio communications controlling about 45% of the market. It would be super stylish and discreet if you had a Motorola radio-earpiece to accompany your radio.
Hytera is another one of the best connectors you can find on the market. Its products are easily available on leading websites with all the necessary accessories. There are plenty of different two way radio earpieces designed by Hytera but most of them come with few accessories less or more. There is not much difference on how they are built or in their quality.
One important thing to have in mind is that there are three basic types of two way radio earpiece kits ; the 1-wire, 2-wire and 3-wire. A 1-wire kit and 2-wire kit features a single combined microphone and “push to talk button†which clips to your collar. A wire with an earpiece then extends from this button, but from the connector on the 2-wire.
A 3-wire kit has a wire with a combined “push to talk†button and microphone that can be run down cuff or collar. There is another wire with an earpiece clip on it. Other kits have a second push to talk button that clips to your pocket or belt near the radio.

GPS Tracking: The Way It Works
GPS (Global Positioning System) is a network of 24 satellites placed in orbit for navigation purposes. It was invented in 1960 and positioned by the US Department of Defense for military work but later released to the public as well. GPS navigation system works 24 hours a day anywhere in the world, and is free to use. The system sends signals to navigation devices to calculate the exact location, time and speed of a vehicle, person, aircraft or water equipment. Today it’s used widely by drivers, trucking companies, and shipping firms to track their cargo and know the best route to use.
How GPS Tracking Works
There are at least four satellites available anywhere one stands on earth. All the satellites circle the earth two times a day and send signals to various areas. Any GPS receiver including mobile phones takes this signal information and calculates the user’s location.
How this method works involves calculating the difference between when the signal was sent and when it was received. This difference tells the receiver how far the satellite is, and the distance comparison of several satellites within the same area confirms the location on the electronic map.
The more satellites found within a receiver's location, the easier it is to calculate speed, distance, and destination. At least three satellites are needed to calculate position, but a fourth satellite makes it possible to tell the speed, direction and estimated time when you are on the move.
Personal Tracking
Mobile GPS technology has made it possible to track people wherever they are. Today any phone can be tracked by the police or mobile service providers. Other mobile devices that help with tracking include jewellery such as watches, bracelets and even chips embedded in the skin.
Smartphones are also equipped with built-in GPS system that can provide the user with direction and navigation instructions. Most of these phones can tell you exactly where you are, including streets and attraction figures. They can alert you if you are going the wrong direction and give you the correct navigation.
Asset Tracking
It is so easy to track your cargo when it’s on the go. A tracking device or chip can be placed on the assets to know exactly where they are, the direction they are heading and when movement stops. Animal tracking devices are also commonly used to locate where cattle and wildlife are all the time.
Aircraft Trackers
GPS aircraft tracking is essential for both private and commercial planes. Though the primary agenda is safety and convenience, GPS works differently on the aircraft as compared to how it’s used in cars. Aircraft tracking enables traffic controllers to know the position of the plane and keep it safe when flying.
GPS also help the supervisors know when the plane will arrive and find it in the case of an accident. However, the greatest use of GPS tracker in aircraft is to ensure the pilot follows a particular path predetermined by the aircraft controller.
Vehicle Tracking
A GPS-enabled tracking device is placed on a vehicle to transmit data through cellular or satellite networks. This device will send the data to a chosen application such as NetTrack for the user to read. The tracking updates and information such as location, speed, direction and stop come in real-time.
GPS tracking system for vehicles enables people to track their cars when they are stolen, keep a tab on your business tracks and know where your child is with the car. It’s an easy and convenient way to keep track of vehicles, be it trucks, small vehicles or fleet of buses.
GPS and Two-Way Radio Integration
Two way radios are great devices used by campers, police force, and emergency dispatch for safety, tracking, and communication. However, they have shortcomings such as lack of real-time transmission, slow updates and being unreliable. Two way radio with GPS makers such as Garmin has integrated their systems with GPS capabilities. The GPS will help to know where someone is at all times even when the device is off, update locations in real time and store data for future use. It’s also handy in case of emergencies to get help and aid search activities.

In the United States and most of the other developed countries, the use of GPS tracker by government authorities is limited. They must have a search warrant. Otherwise, any data found will not be admissible in court.
However, UK Law has no specific legislation on GPS trackers. The United Kingdom does recognize that some information is personal data, but it allows government surveillance without permission.
How GPS Tracking Works
There are at least four satellites available anywhere one stands on earth. All the satellites circle the earth two times a day and send signals to various areas. Any GPS receiver including mobile phones takes this signal information and calculates the user’s location.
How this method works involves calculating the difference between when the signal was sent and when it was received. This difference tells the receiver how far the satellite is, and the distance comparison of several satellites within the same area confirms the location on the electronic map.
The more satellites found within a receiver's location, the easier it is to calculate speed, distance, and destination. At least three satellites are needed to calculate position, but a fourth satellite makes it possible to tell the speed, direction and estimated time when you are on the move.
Personal Tracking
Mobile GPS technology has made it possible to track people wherever they are. Today any phone can be tracked by the police or mobile service providers. Other mobile devices that help with tracking include jewellery such as watches, bracelets and even chips embedded in the skin.
Smartphones are also equipped with built-in GPS system that can provide the user with direction and navigation instructions. Most of these phones can tell you exactly where you are, including streets and attraction figures. They can alert you if you are going the wrong direction and give you the correct navigation.
Asset Tracking
It is so easy to track your cargo when it’s on the go. A tracking device or chip can be placed on the assets to know exactly where they are, the direction they are heading and when movement stops. Animal tracking devices are also commonly used to locate where cattle and wildlife are all the time.
Aircraft Trackers
GPS aircraft tracking is essential for both private and commercial planes. Though the primary agenda is safety and convenience, GPS works differently on the aircraft as compared to how it’s used in cars. Aircraft tracking enables traffic controllers to know the position of the plane and keep it safe when flying.
GPS also help the supervisors know when the plane will arrive and find it in the case of an accident. However, the greatest use of GPS tracker in aircraft is to ensure the pilot follows a particular path predetermined by the aircraft controller.
Vehicle Tracking
A GPS-enabled tracking device is placed on a vehicle to transmit data through cellular or satellite networks. This device will send the data to a chosen application such as NetTrack for the user to read. The tracking updates and information such as location, speed, direction and stop come in real-time.
GPS tracking system for vehicles enables people to track their cars when they are stolen, keep a tab on your business tracks and know where your child is with the car. It’s an easy and convenient way to keep track of vehicles, be it trucks, small vehicles or fleet of buses.
GPS and Two-Way Radio Integration
Two way radios are great devices used by campers, police force, and emergency dispatch for safety, tracking, and communication. However, they have shortcomings such as lack of real-time transmission, slow updates and being unreliable. Two way radio with GPS makers such as Garmin has integrated their systems with GPS capabilities. The GPS will help to know where someone is at all times even when the device is off, update locations in real time and store data for future use. It’s also handy in case of emergencies to get help and aid search activities.

Where You Should Purchase a Walkie Talkie Headset
Walkie talkies are widely used in almost any setting where the portable radio communication is necessary, including but not limited to; loud environments, in forests, in airports, when hunting, in airports, hiking and other outdoor recreation, among others. The units come in handy in situations where many people need to listen, and only 1 needs to talk at a go, for instance, when giving instructions to workers on a camping site. In other words, Walkie talkies are a great communication tools to have, regardless of whether you're using them for fun, at home, or at work, to help in facilitating things to run smoothly. That being so, they have one major limitation, and that's the fact that they're hand held devices which you've to carry with you at all times, and handle whenever you want to communicate. If both of your hands are full, then that can be very inconvenient. Fortunately however, today, there lots of accessories you can use, such as the Walkie talkie headset, which frees up your hands, thus allowing you to talk or communicate with much ease. Moreover nothing helps enhance the audio quality of the Walkie Talkie more than the headset.
To use the headset, you simply need to plug it into the Walkie talkie, and then you can leave the unit clipped onto your belt. The headset will allow you to not only hear clearly, but it also helps in cancelling out noise from your surroundings or environment. The boom mic of the headset allows you to talk directly into the Walkie talkie without having to hold the device up near your mouth.
Radio Connector Types
Walkie talkies don't use the same types of connectors for attaching the speakers, earpiece/microphones or headsets. Today, there are many different connector types available on the market. Even different Walkie talkie models from the same company might have different connector types. Actually, just because 2 different radios have a same physical connection socket, doesn't always mean that they're internally wired up the same way; this means that you should never assume that having the same socket means similar accessories will work in both Walkie talkies. So always be careful when choosing the connectors for your radios.
Active vs Passive
The Active Walkie talkie headsets normally manage the ambient sound that's around it, and send a similar frequency to unwanted sounds to cancel it out; this increases the sounds to noise ratio of unwanted sounds, eventually cancelling the noise out. The Passive Walkie talkie headsets rely on the insulated or the sound absorbent material to muffle the sounds; this is a cheaper option which only protect ups to a certain decibel level.
Conclusion
Today, there is a wide range of walkie talkie headsets to choose from. Your choice should depend on your particular needs, however, you should also make sure you choose one which will work great in your particular ambiance. If you are looking to buy a Walkie talkie headset, contact Headsetonline.co.uk today, and we will gladly provide you with the perfect unit geared to meet each and every one of your needs.

Where Are You Able To Buy a Great Walkie Talkie?
If you’re planning a family outing where you’ll camp for several days, or if you’re headed for an amusement packed backpacking expedition with friends, you might want to know where to buy 2 way radio communication systems. These gadgets are very small in size, and you can go with them wherever you want to as most of them weigh less than half a pound and you can hardly feel burdened by them as you hike.
Additionally, they come in very handy in regions where cell phones cannot dare venture. Some top quality walkie talkies can provide a huge array of features such as weather alerts as well as SOS signals. 2wayradionline has all kinds of two-way radios including the newest types that come with better-quality frequency options as well as radio ranges.
Types of two-way radios
Bearing in mind that there’s a myriad of two-way radio systems available in the market, arguably the most important question to ask yourself if you want to buy a walkie talkie is: what’s the best choice? However, this isn’t a very hard decision once you understand where and how you’ll use it. Firstly, you’ll need to pick either of the two main kinds of two-way radios, which are family or consumer walkie talkies and professional business walkie talkies.
Within both kinds, you would also want to decide whether a radio system with licensed or unlicensed band is most suitable for you. On the one hand, licensed radios come with powerful 5W frequency transmissions and a wider coverage range. However, you’ll have to be contented with a frequency fee. On the other hand, unlicensed band walkie talkies attract no fees, but they’re comparatively low in power plus a limited range that’s only suitable for casual users.
You would also want to decide between an analogue and a digital walkie talkie. Some businesses search for radio systems that can operate suitably in risky highly explosive environments. Radios with ATEX certification are highly recommended in such areas. You can find all these kinds of walkie talkies and more at 2wayradionline
VHF or UHF walkie talkies?
An important consideration when looking to buy walkie talkie is keeping in mind that Ultra High Frequency (UHF) radios will be your best purchase in most cases. Essentially, a UHF radio can never send or receive communication to a Very High Frequency (VHF) radio. As such, if you have some walkie talkies and you’re only looking to add some more units to be used with what you already have, go for the same band.
VHF radios can provide more coverage with less power, but they only function well when there’s little interference between the sender and the receiver. UHF walkie talkies function best with most users since they have shorter waves and can penetrate or get around areas of interference such as hilly areas, thickly wooded areas, in buildings as well as in urban outdoor settings. If you’ll use your radios strictly indoors or if it’s a combination of indoors and outdoors, then UHF is the best choice. You can choose from some of the best VHF and UHF two-way radios at 2 way radio online

Intel Made A VR Headset And It's Totally Cord-Free
Intel just announced its own virtual reality headset called Project Alloy, a VR competitor to the Oculus Rift,HTC Vive and the forthcoming PlayStation VR headsets. But what separates the Alloy from the pack is that it’s completely wireless (the wire above is for capturing video for the demo) and it should give you complete spatial awareness without all the dongles the Rift and Vive currently require.
It does this using two of Intel’s RealSense cameras to continuously map your environment. It can even map your hands.
Intel calls the idea “Merged Realityâ€, essentially combining inputs from cameras around your environment into a virtual world. And Intel was able to pack everything â€" the processor, sensors and controllers â€" into one cord-free headset.
During Intel’s demo, however, the RealSense camera didn’t seem quite as fluid as you’d hope, especially if it’s your primary means of reacting to the digital world around you. Intel says that its hardware will be open source in the second half of 2017 (ugh), so the headset won’t be available anytime soon. Intel is also working with Microsoft so Alloy can run Windows Holographic, the software which powers Hololens, according to Microsoft’s Terry Myerson. Microsoft says that Windows Holographic will also be released in an update for all Windows 10 PCs next year.
