How To Look After Your 2 Way Radio

Buying two way radio equipment is a very beneficial investment, but in order for you to get the most out of your money you should ensure that the equipment is well cared for. If you use and maintain your 2 way radios with proper care, they will function at their optimum capacity and you can expect them to last for many years. While no two way radio can last forever, there are some simple practices which can help extend the life expectancy of your two way radios and ensure they function at their very best. In this article, we are going to take a look at some of the top care tips for your 2 way radios;

Storage

You should always store your radio(s) correctly so as to keep it in a tip top condition. The ideal environment for storing your radio involves a cool and dry (ideally at room temperature, which should be about 72 degrees Fahrenheit) with limited exposure to the extreme weather conditions like excessive cold or heat, and such other elements of water and sunlight. Excessive temperatures can easily damage the batteries; the moisture may end up corroding the batteries. Also, when storing your two way radio, you should make sure that it's turned off and batteries are removed.

Charging Your 2 way Radio



First of all, you should know that two way radios are usually slightly different , so you need to familiarize yourself with the specific charging instructions of your radio. That being so, it is important to note that nearly all of the manufacturers will advise that you to turn off your radio while it’s charging. If you do not, your radio will be drawing current and also charging at the same time, and this can end up shortening the lifespan of the battery.

Overcharging your radio batteries can also cause numerous problems and will have a negative impact on its' overall battery life, so you should make sure that when it's charged fully you unplug its' charger; do not leave it charging all through the night if its' likely to remain fully charged for a long period of time while its' still being charged. When you buy new batteries its' the only time you can leave the radio charging overnight before you start using them for the 1st time; it'll help you get the maximum battery capacity.

Day to Day Use

Every 2 way radios user should be very mindful of their daily use. Although there are some 2 way radios which are designed to be quite robust, like the explosion proof and waterproof radios, they should still be treated with great care, always. Even if you have a waterproof or explosion proof radio, do not subject it to extreme temperatures.

You should also avoid grabbing your two way radio by its' antenna, as this will eventually have a negative impact on your radio's reception and transmission quality. In addition, you should also avoid drops so as to maximize the long term functionality of your radio; consider using 2 way radio belt clips so as to reduce the chances of your radio getting dropped and subsequently getting damaged. Protecting the exterior of your radio helps protect its' interior, thus minimizing the repairs and the replacing of the equipment.

Another important tip to note when it comes to the day to day use of 2 way radios, is you should never expose your radio to any solvents (unless it has been designed to be used in the harsh conditions); this includes any cleaning fluids and alcohol. Also, try and stick with the accessories which are designed specifically for your particular type of radio; this is especially important when it comes to your radio battery, charger and adapter. Using an incompatible accessory can end up shortening your radio's lifespan and can even destroy it.

Cleaning Your two way Radio

You should regularly clean your radio to keep it in good working condition. The most effective and efficient way of cleaning your 2 way radio also happens to be one of the easiest ways as well; strong chemicals or intensive cleaning isn’t necessary. The only supplies you'll need include some water and a microfiber cloth. The microfiber cloth will effectively wipe away the smudges and dirt without causing any damage to your radio. As for the more stubborn marks and stains, you can use a damp cloth and then wipe until the radio is clean. Remember, never immerse your 2 way radio in water to clean it.

Conclusion

2 way radios are among the most versatile and toughest communication solutions, often lasting for many years before needing any repairs or replacement. However, in order to extend the lifespan of your 2 way radio even further, it is best to employ the above tips for 2 way radio care to fully secure your investment. Protecting your two way radio will not only increase its' longevity, but it also ensures that you will always have reliable communications. Well, as you can see above, taking care of two way radio is relatively easy, and the amount of maintenance required is minimal. A simple cleaning now and then, proper handling, maintenance and storage is all you need in order to extend the lifespan of your 2 way radio and keep it in a great working condition.

5 Examples of Earpiece to Hear Far Away

1. Using a Mobile Phone And Bluetooth headsets or Earpiece

To do this, you simply need to go into your mobile phone's settings and then change answering mode to Auto; this enables your phone to answer automatically when you ring it. Most mobile phones only work in the Auto answer mode, after you have plugged in the headset.

After turning on the Bluetooth headset, make sure it's properly paired with your cell phone, and confirm the battery has adequate charge. Hide your Bluetooth headset somewhere you know it'll pick up the sounds clearly, however, make sure that it's well hidden.

Leave the room, however, do not go very far. The Bluetooth connection will work through the walls, but if you happen to go far away, it'll not work very well (the range can be up to about 30 feet or 3 rooms away). Now test your cell phone by calling it to see how far you can actually go and still get to hear the bugged room through the Bluetooth headset.

You can wait for the conversations to get to the interesting part, and then turn on voice recorder on the cell phone; it should be able to record via the microphone of your Bluetooth headset.

2. Using a Two Way Radio and Earpiece

Two way radios allow users to communicate when they're far away such that they can not hear each other. These devices use radio frequencies instead of cell phone towers which means they will work in areas where there's no cell phone coverage or reception.

The two way radios offer instantaneous communication; users simply need to press the Push-To-Talk (also known as PTT) key, and they can instantly talk and convey their particular message to the other party. This is due to the quick call setup time that's entrenched in this technology. The ability to offer quick communications is one of the reasons why most organizations prefer the two way radios for their tactical and operational communications.

Another great feature of the two way radios, is the ability to facilitate one to many (also known as, group calls) communications effectively. This basically means that a single user can conveniently communicate with 2, 10, 20, and more, of other two way radio users at the same time. In short, there is no need for you to repeat time and time again when you want to communicate with many people and using a two way radio earpiece, this communication is much more secure

3. Ear Spy Application

Ear Spy App is a great eavesdropping tool. Depending on just how good your cell phone is, this app can become a very high powered listening tool. Ear Spy application can route the audio from your cell phone's mic right to to your headset letting you eavesdrop on the people around you whilst remaining inconspicuous. When using a Bluetooth, you can use this app to spy from a room nearby; you simply need to leave your cell phone near the target, and then use your Bluetooth headset to eavesdrop. If you want to fine tune the incoming signals, you can use the graphics audio equalizer. Whether you wish to eavesdrop on particular conversations or you just want to play some spy games, Ear Spy application will be of great help in your endeavor. You should know that this app requires you to use headphones, otherwise you will get poor audio feedback.

4. Spy Glasses

This spy device comprises of an in built Bluetooth transmitter which looks like ordinary glasses, a microphone and a wireless earpiece. Connections between the glasses, the earpiece and your cell phone are wireless, thus totally unnoticeable to other people; the device's ultra compact design basically ensures nobody will know it is a spy tool. Spy glasses are compatible with almost any mobile phone which has the Bluetooth option. Actually, the Spy glasses are universally compatible with all the standard Bluetooth enabled equipment including computers. Some of the features of this device include; excellent transmission and reception of audio signals, built in microphone, and a large capacity Lithium battery.

5. Micro Air Vehicles (MAVs)

Modern technological advances are ever increasing human's potential for developing tiny things. As for the United States Air Force, this translates to revolutionary designs in the air vehicles to provide the war fighters with new tools which can enhance both the situational awareness, and also the capacity of engaging quickly, accurately, and with minimal collateral damage. This is where Micro Air Vehicles (also known as MAVs) come in. The term MAV or micro air vehicle, refers to the a new type of advanced remotely controlled aircraft (abbreviated as, UAV) that's significantly much smaller than other similar aircraft. Typically, MAVs can easily blend in with the surrounding environment, stay in air for a long period of time, and can go places which can't be reached safely by humans, or most of the other types surveillance equipment.

The target dimensions for MAVs is approximately 6 inches (15 centimeters), and the development of actual insect sized aircrafts is expected in near future. As a matter of fact, various efforts in the research on micro air vehicles have involved attempting to mimic flying insects so as to achieve the flight capabilities which aren't attainable through the use of other means of aerial propulsion. In the year 2007, a bug like Micro air vehicle model with a wingspan of 3 cm was revealed at a robotic's conference; in the year 2008, the United States Air Force released a video showing Micro air vehicles which were the size of a bumblebee; and in the year 2012, some engineers from Johns Hopkins University started studying flight of butterflies to discover how airborne robots can mimic their maneuvers.

The potential military use is 1 of the key driving factors, although the micro air vehicle can also be used commercially, as well as in scientific and mapping applications. The main military use envisioned for the micro air vehicle is gathering of intelligence via the use of microphones, cameras, or other types of sensor.



Conclusion

Some of the above points are illegal, and you should not do any of them. Also, do not use any of the above methods to record any intimate relations; the legal consequences of doing so are very severe. Finally, keep in mind that it's illegal in the US to make recordings of people without their consent/permission; and depending on what you'll do with the recordings, you might find yourself in big trouble.

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.”

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.”

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.”

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.”

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.”

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.”

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.

Chinese corporation bids to acquire Sepura

This news is making quite a buzz within the stock market forums, With two of our big players in our industry set to merge, this is huge news! Yes, Sepura have had their problems this year and Hytera have increased their market share, but we are not sure is this is good news or bad?

Another Asian corporation is set to hoover up a Cambridge UK technology company in a state of financial flux.

Communications technology business Sepura confirms it is in talks with Chinese company Hytera Communications Corporation Ltd.

It will be an all-cash deal but the acquisition price will be moderate because digital radios company Sepura is in a mess because of cash liquidity issues.

Sepura revealed the takeover talks after its share price spiked more than 25 per cent having nosedived in recent times due to cashflow issues and order delays.

Hytera is a world leading solution provider of professional mobile radio communications and operates globally.

Late today, Sepura issued a statement on London Stock Exchange confirming it was in preliminary talks with Hytera regarding a possible offer for the entire issued and to be issued share capital of the company.



Hytera confirmed to the Sepura board that any offer was likely to be solely in cash. The usual caveats were issued that there was no certainty any deal would go through and shareholders would be updated on new developments.

Founded in 1993 in Shenzhen, China, Hytera has grown to be a key player in the PMR (Professional Mobile Radio) communication industry with a large customer base in more than 120 countries and regions across the world.

In China, Hytera's market share ranks first among Chinese manufacturers while globally Hytera has reached second place in the overall terminal category.

As one of the few corporations that masters TETRA, DMR and PDT technologies, and produces all series of products and solutions of all these mainstream digital protocols, Hytera leads in the draft of digital trunking standard in China.

Its acquisition of the Rohde & Schwarz TETRA business in August 2011 further strengthened its competitive edge in TETRA market.

Hytera has established a global sales network with 30 branches in the US, UK, Germany, Australia, Brazil and other territories and through  600+ partners across the world.

Hytera has an R & D team of over 1200 engineers in five research centres. Sepura won the Business Weekly Awards Business of the Year title in March after a record-breaking

2015 but hit liquidity problems this summer and has temporarily lost its CEO Gordon Watling to ill health.

Music From Your Sunglasses? Zungle's Founders Crowdfund $2M For Shades With Bone-Conduction Speakers

Anything with bone conducting technology, we will jump upon and love the hell out of! When we heard about Sunglasses that had speakers with bone conducting inside, to allow you to make calls and listen to music whilst on the move we thought what a great idea. This crowd-funder is looking to raise $50,000 but $1 million would be a good start. See more on this here.

One of the latest hot crowdfunding campaigns is for dark sunglasses called the Zungle Panther with bone-conduction technology that allows them to be used to listen to music and make phone calls. Jason Yang, Zungle’s 30-year-old CEO and co-founder, came up with the idea because he was annoyed with trying to wear an earpiece and sunglasses to listen to music while wakeboarding.

“We all love extreme sports, and Jason is a huge fan of wakeboarding,” says Sean Bang, 30, Zungle’s chief marketing officer and co-founder. “He’ll have sunglasses on, but eventually the earphone doesn’t work with the sunglasses, and he felt that it was inconvenient and uncomfortable. So we decided to get rid of the inconvenience.”

With Zungle’s sunglasses, wearers can listen to music or make phone calls while skiing, biking or wakeboarding without worrying about an additional earpiece. Bone-conduction technology, in which you hear sound through vibrations to your skull rather than through your ears, isn’t new. But the idea of putting it into relatively inexpensive consumer products, like sunglasses, has been gaining traction recently.



So after fiddling with the product for nearly a year, in June, the two friends, who had worked together at marketing firm Innocean Worldwide in South Korea, along with two other cofounders, Chris Hong and Injun Park, turned to Kickstarter with a stated goal of $50,000 for their high-tech sunglasses. As with many crowdfunding campaigns, that $50,000 number was a lowball one; Yang says “about $1 million” was their actual goal. The Zungle Panther has a similar look to Oakley’s shades, and retails for $150. Backers who chipped in $89 could get them in a choice of colors as a “reward.” “When we started, we didn’t have enough money to create this product,” Bang says. “We chose Kickstarter because we can target everyone around the globe.”

By the time the campaign ended, in mid-July, Zungle had raised more than $1.9 million, putting it among Kickstarter’s top 100 campaigns of all-time.

AXUM: THE FUTURE OF WIRELESS AUDIO

This article is the transcript of an interview with Igal Golva, CEO of Axum earphones, wireless earphones with secure fittings, designed for people doing exercise. A really interesting article about why these earphones are different to others on the market and what their plans are for the future of the company.

Mobile audio has always been a difficult balancing act. The need for great audio on the go has never been more prevalent. With smartphones now a staple for most people’s daily commute, exercise and fitness, the need for an audio solution that can be portable while still sounding good is the holy grail.

Apple, with the iPhone 7 has also forced people’s hands. The headphones they used to use are no longer as easy to pull out and plug in without the use of a dongle. This is where Bluetooth audio options come into play, and where the Axum wireless headphones are planning to make a splash. Currently on Indiegogo, the Axum are aiming to give people great audio, while ensuring they maintain that mobile, ultraportable feel. Currently at 528% funded, the Axum is proving to be a product many people want to get their hands on. We had a chance to talk to Igal Golvan, CEO at Axum, about what the headphones can do for audio and fitness and how they hope to change the way people view Bluetooth audio.

Axum: The Future of Wireless Audio 1

CGMagazine: Could you tell us a little about what Axum does and how these new headphones stand above the competition?

Igal Golvan: First of all, we not only offer four hours playtime (while others offer 1.5-2 hours) you can also get an additional four with the portable charging case. We achieved it by eliminating any unnecessary features. We are aiming to reach fitness junkies like us that need three things: fit, sound and battery life.

Our designers made a unique design that will fit you during the most extreme sport activities. In the last months all we did was test the earphones in every sport activity you can imagine .This included cycling, running, CrossFit , snowboarding and even sky diving .

The issue with True Wireless Earbuds is that all our competitors see this product as the latest technology in the headphones industry and as such they've aimed the technology at early adopters. Unlike them we understand the real potential of the product to become the mainstream earbuds of athletes, as the lack of cables is something so comfortable no one can even imagine, only when doing sport activities and listening to Axum earphones will you really understand the definition of freedom!

Axum: The Future of Wireless Audio 2

CGM: Could you go over what M-voiD® sound technology brings to the table?

IG: Sure. M-voiD stands for Multidisciplinary virtually optimized industrial Design. It’s a technology for the realistic simulation of audio systems using CAD data. It is a sophisticated technology that paves the way to reproduce outstanding sound performance to let consumers discover that earphones deliver the emotions and excitement comparable with a concert.

Realistic and predictive simulations by means of a fully coupled multiphysical electrical-mechanical-acoustical simulation model are the heart and driving backbone of M-voiD® technology. The major advantage of M-voiD® is that acoustic problems can be identified and resolved in the virtual domain before any prototype is being built.

Sound characteristics are virtually measurable and assessable and can be optimized on the virtual model. It is not just limited to the graphical reproduction. M-voiD® listens to the virtual sound of the earphone already on the computer by means of a special reproduction technique (called auralization), enabling improved sound. Bottom line, while even the largest companies out there can test 100 or maybe 10,000 prototypes to check and improve the sound quality before releasing the final product, we had the ability to test sound quality from over 10 million prototypes.

Besides that, Konzept-X also helped us with the driver design itself to maximize the results after we've changed the internal design.


Axum: The Future of Wireless Audio 3

CGM: With your Indigogo doing so well, do you foresee this will delay the final release?

IG: Exactly the opposite. We planned to wait until the funding period is over to head into mass production, but now that we understand the demand we'll start doing it ASAP.

CGM: Why the choice to go with Indigogo over an option such as Kickstarter?

IG: We thought about KS, however the Indiegogo team was much more supportive and offered lots of relevant information on how to succeed with crowdfunding . We are product people and don't understand crowdfunding, so a supportive team was something very important for us.

CGM: Do you plan to offer a retail version of these headphones?

IG: Of course, but first we'll ship everything to our backers and then we'll think about retail.

CGM: For the gamer on the go, will these offer anything beyond what is already in the wild?

IG: The perfect fit of Axum earbuds is something like you've never experienced before, you can see the bulky design of other brands such as Samsung and Motorola The last thing you want to do is wear those gigantic things all day long.

Axum: The Future of Wireless Audio 4

CGM: How do you think these headphones will do with the fitness crowd beyond just the music listener?

IG: We believe that beside the sound quality, the fit and comfort is something they'll be addicted to. We noticed the reaction of the people while testing them out in the gym and we guarantee that once you try Axum earbuds you'll never be able to use wires again!

CGM: Are there any obstacles you will need to overcome to bring these to market?

IG: Yes, there are many obstacles of unawareness from the customers. Many people are not familiar with this concept and think of it as a regular mono Bluetooth ear piece, so we are heading to a long journey of explaining our product and turning it into mainstream.

Axum: The Future of Wireless Audio 5

CGM: How do you feel these headphones will do with a crowded market? What sets Axum apart?

IG: We have full confidence in our product. First of all we know 100% that no matter how good your BT earbuds are, if they are not True Wireless they can't compete with us. As for other True Wireless companies out there, based on their design they've never thought about athletes as their potential customers and it's a shame as this concept is perfect for fitness and exercising. So we already have a huge advantage on them.
