Sorry, but youâve been had. Although many manufacturers boast that their radios can reach amazing distances, this is, in almost every instance weâve encountered, a fallacy.
How is this legal, you may ask?
Essentially, your radio quite probably could work over a range of 25 miles, but that is a theoretical estimate, working on the assumption that the myriad variables that affect two-way radio signal (such as atmospheric conditions, topography, objects in the way and etc) are simply not in effect.
All of them. At the exact same time.
So, assuming that you used your two-way radio in a vacuum, where weather didnât exist and no obstacles, man-made or otherwise, were present, you would be able to communicate with someone else who was further away in that impossible vacuum, maybe even 25 miles away, but otherwise? Forget it.
The fact is that the average two-way radio has a range of between one and two miles and not much more (maybe three, but weâre not making any promises). CB radio fares significantly better, largely because it makes use of large aerials. Now, Signal-boosting equipment can be used to improve your two-wayâs performance (for example, repeaters), but such equipment is expensive and hard to obtain for legal reasons.
There are, however, a few factors that can have an affect on your radioâs range. The frequency being used, the power output, the size of the antenna, the complexity of the signal being sent, signal interference, background noise and (as we wrote earlier) objects in the way are all factors that can improve (or hamper) your efforts to get your signal to reach as far as possible.
However, a larger antenna (if youâre tech orientated, the antenna can be replaced with a better one â although this should only be attempted if you are
a) Sure about licensing laws
b) Tech savvy enough to void the warranty and not regret it later, can really add a few hundred meters to a radioâs range, as can a switch in frequencies.
Also, your choice of VHF or UHF radio will have an affect as well, a UHF signal, for example, generally penetrates buildings and objects better than a VHF signal, whereas VHF is better for outdoor use where there is a lot of open space to transmit across.
Having said/written that, even in optimum conditions, you are extremely unlikely to transmit over a distance of 25 miles. Sorry.
As an aside, mobile phones donât suffer from this lack of coverage, largely because cell towers are in place that bounce the signal from one to the other and thus carry it across a far larger area, your mobile is still your best bet to break that 25 mile mark, weâre afraid.

Communication is the key to any business being successful, but communication comes in lots of different forms, understanding the right and proper way of communicating will see you through in your career very well. This article is a very good overview of what communication can mean to you.
As a professional, you certainly know the importance of effective communication. Being an effective communicator is not only about the message, itâs also about the mode of communication and the opportunities you provide for feedback.
Your inability to get the point across thwarts your efforts at effective communication. You canât just send out a company-wide email and assume everything is copacetic if no one replies. The truth may be that you were ineffective as a communicator, and people didnât understandâor even pay attentionâto your message.
There are some things you might be doing to undermine your effectiveness as a communicator, and you may not even know youâre doing them. Here are some communication pitfalls you should try to avoid:
Youâre not an effective communicator if you just repeat the same message over and over. If you want to remind your employees about an important deadline, sending out a single reminder would be appropriate. Sending out multiple reminders, however, is overkillâand possibly even an insult to your employeesâ ability to remember information.Â Redundancy in your messagesÂ is not only unnecessary, but itâs also counterproductive and a waste of timeâfor youÂ andÂ your employees. Whenever you send out communication on an ongoing subject, make sure it offers added information and is not merely a reiteration of the material you already shared.
Relying Too Much on One Channel (Or the Wrong Channel)
Todayâs technology makes it possible to communicate in many different ways. While itâs easy to do, you shouldnât get stuck in one particular communication mode. There are so many digital communication channels that work really well these days. Email is a popular tactic and can work well, but people are inundated with email today and often suffer from âin-box overload.â So, you may want to consider using a combination of tactics for impactful news, such as the announcement of a merger or a high-level addition to the company management.
Nobody likes to be the bearer of bad news, but it doesnât help the situation to be vague or unclear. You should try to deliver important news in personâand the more complicated or easily misunderstood the message is likely to be, the more it makes sense for you to sit down across from the personâor teamâto convey the message. A direct, in-person approach adds an important component to your communication: The ability to observe othersâÂ facial expressions and body language, which allows you to ensure your message has been understood.
Ignoring Nonverbal Cues
If you listen only to a person words and ignore their nonverbal cues your direct communication may not be successful.Â Research conducted by Dr. Albert MehrabianÂ indicates that 55 percent of our intent is delivered through nonverbal elements, such as facial expressions, gestures, and postures. If employees seem to express agreement with a new policy,Â non verbal cuesÂ such as hunched shoulders, crossed arms, and lack of eye contact may indicate that you still have some work to do in order to get buy-in from your team.
Not Being Open
Secrecy in the workplace oftenÂ erodes trust in leadership and foments gossip. By being more transparent in your communication, you foster a sense of belonging and trust. Knowledge replaces speculation, and can help reduce gossip and rumors.
Rememberâcommunication is a two-way street. Soliciting feedback is one of the greatest ways for you to know what employees are truly thinking. If you want to improve your communication skills, heed this advice:Â Speak less, listen more. After youâve had the opportunity to listen, you can fine-tune your communication skills to be more effective than before.
Effective communication is crucial to the success of any business. Poor communication can easily lead to the collapse of any business regardless of size. If youâre running a huge business where keeping in touch with your staff is important, then you must put in place a very efficient communication system. A system that is not only efficient but also cost effective. These two factors are the reason 2 way radios are popular with modern businesses. A 2 way radio is a communication device that can both transmit and receive signal. It allows users using the same frequency to have a conversation at minimal or zero cost.
Why you should consider using a 2 way radio for your business
There are numerous benefits that a business will enjoy by making a 2 way radio its choice of communication. First, the radio provides a platform where you can conveniently keep in touch with your staff anytime you want. If you are the manager and the firm has several departments where you cannot physically access the staff, then this is the perfect device for you. Second, itâs easy to manage, unlike mobile phones that rely on the service providers. With radio system, you manage it from your premises.
The fact that a 2 way radio can only receive and send information at a set frequency improves your business’ safety. You can keep the frequency a secret such that only certified individuals can access crucial information. The radio also allows you to create several channels for specific groups. This option allows you to call individual groups whenever the need arises. For example, if the information is meant for security department, it will not be necessary to have it broadcasted to other groups.
Its broad geographical coverage is another reason you should have this communication gadget. If your business Covers a vast geographic area such as a farm or a construction site, this is the perfect mode of communication to employ. It can also be an effective security monitoring system if it’s well managed and utilized. Combining this system with GPS and the CCTV can significantly improve matters of security for your business.
But who can use the 2 way radio system?
A 2 way radio is one of the most user friend and flexible communication gadgets. Any firm can use it regardless of size. The radio is indeed the perfect model for a business that is struggling with geographical coverage challenges. It is ideal for shift workers, security staff, production line inspectors, farm workers, construction sites, shop watch and the list is endless. Anyone can use it. It only requires a little bit training on how to receive or to send a signal, and the user will be good to go.
Advantages of 2 way radios
One thing that stands out from this system is the reduced cost of communication- the cost is almost zero-rated compared to the other systems such as mobile phones. A 2 way radio is also very simple to use since you simply press the button to start talking. This speed can be crucial in cases of emergency compared to mobile phones where you will be needed to dial several buttons to make a call.
With this radio system, you can talk to multiple users at once- this is not possible with mobile phones. The gadget is built to military specs -the radio can be used in wet conditions and can withstand even a drop on the concrete surface. 2 way radio is one of the devices that can work in all areas of your business where mobile phones donât work. The last but not the list of the advantage is that the radio stays on site, and thus different shifts can conveniently share it.
Key questions before installing a 2 way radio system
There are several questions that you must get clear answers to before you install a 2 way radio system. First, the area that the radio system is going to be used must be known. This will determine the power of the transmitter needed to cover that area. The number of people projected to use the radios should be the next question. The answer gives the number of radios required. The last question should be your budget. You must purchase what you can afford without compromising on the quality. With these questions answered, then you can have the most efficient 2 way radio communication system for your business.
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 âvarietyâ 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), âEmployees shall be given the opportunity to select their hearing protectors from a variety of suitable hearing protectors provided by the employer.â But does âvariety of suitable hearing protectorsâ 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 safety managers offer several different large foam earplugs that are yellow, green and orange â mistakenly assuming they meet the âvarietyâ 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 âvarietyâ actually limits the number of workers adequately protected.
This bad assumption is often codified into company safety policies that require a minimum NRR: âApproved hearing protectors must have an NRR of at least 32 decibels,â 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?
Size:Â Like a cork in a bottle, an earplug that is too 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. Itâs not necessary to carry a dozen different earplug styles.
Finally, any offering of hearing protection needs a hands-on training component. How can a workers determine whether their ear canal is large or small, round or oval? Itâs 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.
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 peopleâs 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 peopleâs 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 toÂ 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.
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!
CGM: Could you go over what M-voiDÂ® sound technology brings to the table?
IG: Sure. M-voiD stands for Multidisciplinary virtually optimized industrial Design. Itâs 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-voiDÂ® technology.Â The major advantage of M-voiDÂ® 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-voiDÂ® listens to the virtual sound of the earphone already on the computer by means of a special reproduction technique (called auralization), enabling improved sound.Â 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.
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.
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.
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.
When choosing the best two way radio, it is important to note that doesn’t matter which brand you pick. Whether you pick kenwood, Motorola, Icom, Hytera or any other brand, you should know that they all feature the same technology. Well, you might have noticed that most consumer radios tend to advertise a range that’s up to 30 miles. Truth is, the consumer FRS/GMRS radios don’t even provide anything close to the advertised maximum range; the range that a two way radio advertises is normally the range that a radio can get in the ideal condition. The ideal condition is clear line of sight like from the mountain top to the valley below; without any interference or obstructions.
Two way radios generally operate within VHF (that is Very High Frequency; 130 to 174MHzz) and UHF (that is, Ultra High Frequency; 420 – 470 MHz)) wave bands. Unlike the frequencies that are below 2MHz, the waves in these particularly higher frequencies travel in a straight line (also known as line of sight signal), and generally can’t travel beyond your horizon. This basically means that distance to your horizon, is the actual maximum range for your two way radio ; that is without the use of any additional equipment to boost the signals.
VHF waves (about 5 feet wide), are generally longer than the UHF waves, and they’re most commonly used for long range/distance communication. If VHF waves and UHF waves were both transmitted in ideal conditions without any barriers, the VHF waves would travel nearly twice as far; as a general rule, the lower the wave frequency, the greater the distances it can travel.
Key to transmitting the radio waves for a long distance along the VHF waves is keeping the receiver and the transmitting radio above all possible obstructions or interfering objects. The VHF frequencies (because of the length of their waves), cannot transmit through some objects like walls, dense forests and hills. Typically, the transmissions which are sent along VHF waves are received and also sent high above earth’s surface. VHF 2 way radios normally work better when there is a clear line of sight between the receiver and the sender. VHF two way radios are commonly used in marine and aviation communications where signals get sent across the open water bodies or between the ground and the sky. Television and FM radios also use the VHF frequencies where the signals are sent and also received high at the top of towers which are spaced all over the towns, cities and counties. VHF band walkie talkies are also perfect for landscaping, open fields, golf courses and also for outdoors security situations where there is less obstruction.
Though VHF can travel much farther, it doesnât mean it is the better option. Reason is because of the differences between how the VHF and the UHF signals tend to react around buildings or structures. As you will find out below, UHF signals are shorter than VHF, and this is very important when you’re in or around buildings.
UHF doesn’t travel as far as the VHF, but has higher bandwidth occupation. One major advantage of UHF over the VHF, is that the antenna can actually be much smaller when its’ used on the higher frequencies. Sometimes, a base antenna might be needed for radios using VHF frequency, but a small antenna on a radio can be comfortably used for the UHF frequency. Moreover, there are a lot more frequencies which are available when using UHF; this can be very useful in the areas which have a high population density.
The UHF radio waves are much shorter than the VHF radio waves (measuring at about one and half feet); the short length of UHF radio waves typically decreases distances at which the signals can get transmitted. This means that the line of sight between the receiver and the sender is much shorter in length with UHF waves. That being so, you should know that transmission of the UHF waves is usually high enough such that it can penetrate through the building walls and the urban outdoor settings. This is the reason why UHF two way radios usually work best for those who intend to use them in and around buildings and urban areas. A UHF walkie talkie with adequate power and a good sized antenna can reach further into the building, and push through steel, wood, concrete and earth. If you intend to use your 2 way radios exclusively indoors, or maybe indoors and at times outdoors, the the UHF is definitely the best choice. To explain this, let us use an example; assume you’re trying to communicate with someone on the other side of the building and in between there’s a metal wall which has a 3 foot opening. Basically, radio waves can’t pass through metal. However, the UHF wavelength which is about 1 1/2 ft wide, will easily pass through the opening. In contrast, the VHF signal will bounce back since it’s wider than the opening. This shows you that UHF is much better when it comes to navigating through smaller spaces within buildings to reach its’ destination.
When it comes to power, many people tend to think that the power output increases the range, but actually the difference in the range between, say a 25W fixed VHF, and a 5W handheld, is because the fixed mounts the antenna being taller, thus can see farther. When you are trying to increase the range, increasing the height of your antenna is far more effective than increasing the power. Increased power will generally let you push through the static and such other radio traffic much better, but only within a range that’s dictated by the height of the antenna.
When you think of a spy earpiece, the first thing that comes to mind is inspector gadget or Mission impossible, well it does for us anyway. But there are real world applications for these earpieces are wide. As this article explains, when you need a little help with prompts on a big presentation or you need to receiveÂ instructions during a lecture, then a micro earpiece could be the answer.
This device originally developed for covert operations is now made available for the public to use. Each earpiece kit can provide a way for you to transmit and receive audio information without anybody in the room knowing. Whether you want to receive pre-recorded messages or information from another party to assist you during your presentation / interview or speech, the earpiece can be set up with your phone, audio recorder, radio, or MP3 player to send the message to your earpiece , placed in your ear channel so that it is undetectable .. All kits also include a built in microphone so that you can engage in 2 way conversation should you wish
So how does it work?
The key is the inductive transmitter that will transmit audio from a phone / mp3 player to the earpiece. The transmitter itself is available in many forms. For example the transmitter may be included within a neckloop to be worn around the users neck, this may connect to your phone or mp3 player via its earphone socket. Or you may have a Bluetooth are often included in everyday objects such as a pair of glasses, a Pen or even a bluetooth watch. The transmitter acts as the aerial for reception and signal transmitter from phone to earpiece. At the same time, output sound picked up by the tiny microphone attached to the neckloop / pen / glasses is sent through your phone just as if the user is talking directly into it.
How to Use The Spy Earpiece?
Depending on what kind of information you wish to receive the earpiece can be set up to suit. For example during a presentation or speech you may wish to pre-record your speech or presentation on an mp3 player, then play it back to yourself during the presentation / speech. Or simply record a simple prompt for each point you would like to make. You could then connect up your mp3 player to an inductive neckloop included in most earpiece kits, and wear a spy earpiece. So long as the battery is inserted into the earpiece you will hear the audio from your mp3 player in the earpiece.
Alternatively you may prefer to have a team prepped in another room to assist you during your speech. This can be achieved by simply starting a mobile phone conversation with your team just before the speech starts. You would then need to either connect an inductive neckloop to the headphone output of your phone, or pair your phone with a bluetooth induction neckloop / pen / glasses. Insert the earpiece into your ear making sure the battery is inserted correctly. Your team should be able to hear your speech in real time over the phone, and can give you tips in your earpiece along the way. The same may apply in an interview situation, you may wish to have a third party issue you advice during your interview.
Each Inductive transmitter whether it be a neckloop or a bluetooth device like a pen, glasses or bluetooth neckloop, will also include a built in microphone so you can also talk back to your colleagues should you wish during your speech / presentation or interview.
Lets not forget the original intention of the Spy Earpiece which is for security and covert surveillance. The Spy Earpiece excels in these situations where the requirement is for a security operative to communicate covertly.
The key to success is in the careful planning and preparation so that everything runs smooth.
The way I see it, when the challenge is great and the results mean everything, why not try the Spy Earpiece and take the risk out of the equation?
Motorola Solutions are busy re-modellingÂ their business at the moment and are under pressure from many other radio manufacturers, that are stealing away their market share. They are moving towards creating equipment that can use the LTE, essentially competing with the mobile phone market. This will be seen by many as a move away from the essence of two way radios, but it is an inevitable progression. This new radio will use current motorola earpieces, chargers and batteries. We brought you this article from the urgentcomms websites
Motorola Solutions today will unveil a newÂ P25 mobile radio that operates on its ASTRO 25 systems and will highlight key features enabled by the 7.17 release of ASTRO 25 software today at APCO 2016.
One of the key features of the APX 8500 all-band mobile radio is its ability to leverage LTE connectivity from a VML750 modem installed in the public-safety vehicle, if the ASTRO 25 data capability is interrupted by continuous voice transmissions during a busy incident, according to Anatoly Delm, Motorola Solutionsâ director of global infrastructure marketing.
âLetâs say that you have a major incident, everybodyâs talking all the time and the ASTRO network is being used all the time, it can [offload] some of the data communications, like GPS, to broadbandâpublic-safety LTE or commercial LTE, depending on what the modem is operating on,â Delm said during an interview with IWCEâs Urgent Communications.
âSo, youâve got this combination of the best of both worlds, where your voice communications are continuing over the ASTRO network, and your data communicationsâif the ASTRO network is too busy, because of a major incidentâcan be carried on by an LTE network from the same car.â
Meanwhile, the 7.17 release of ASTRO 25 software will provide system users and operators with features that are designed to improve the reliability and usability of the P25 network, Delm said.
One enhancement is a more efficient way to execute over-the-air software updates, Delm said.
âOrdinarily, what happens is that the software update has to travel to one radio at a time. If youâve got a large enough fleet, it could take days or possibly weeks [to complete the software update for all radios],â he said. âIn this case, the software is being continuously broadcast, kind of like on repeat. In the meantime, all of the radios continue to function as normalâyou can talk on them, and none of the functions are disrupted.
âOnce a radio has received all of the packets that it needs, it can then give the user the [a notification] that the update is ready and asks whether the user wants to install it. If they say âYes,â then the radio is updated. This means you can reduce your update time to maybe a few hours, depending on the size of your fleet. But you certainly donât have to do it one at a time.â
Other new capabilities included in the latest ASTRO 25 software release include personnel accountabilityâoften used for roll-call functionality on a fireground or other incident sceneâover trunked systems, Delm said. Previously, this capability existed only in conventional mode.
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.
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.
Back in the day, around 2006, the Heathrow and Gatwick radio systems were the envy of many, many businesses, a cutting-edge Motorola analogue trunking system with individual and group setup, that could broadcast messages out across the site or talk to individual radios, something that is taken for granted these days with our digital systems. The Gatwick system has been upgraded and been given the digital touch.
US-based Motorola Solutions, along with its authorised channel partner Servicom, has debuted its new digital mobile radio (DMR) system, Mototrbo Capacity Max, at London Gatwick Airport.
Designed to provide enhancedÂ voice and data communications, the newly installed system connects 1,300 peopleÂ in the airport’sÂ airside and groundside teams.
Mototrbo Capacity Max will also double the capacity of Gatwickâs current analogue network.
Various applications, such as TRBOnet PLUS and iBeacon, were given along with Mototrbo Capacity Max to improve its data performance.
TRBOnet PLUSÂ is a dispatcher application thatÂ allows voice recording, mapping and event logging in the control room, while theÂ iBeacon indoor positioning application sends alerts to individual radios based on location.
Gatwick Airport IT project manager Simon Telling said: âWe chose Motorola Solutionsâ Mototrbo Capacity Max system not only for how resilient and secure it is, but because of the flexibility it offers us now and into the future.
âWe have experienced significant growth over the past decade and we are now approaching the limits of our previous analogue system.
âMigrating to scalable, digital communications will double our capacity and bring new capabilities that will help us improve efficiency and safety for staff, retail partners and passengers across the airport.â
The new Motorola solution will also enable Gatwickâs central controllers to send off the closest employee to an incident, saving time.
The airport recorded more than 4.6 million in passenger traffic in July.
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.
âThe only communication out there on 9/11 was amateur radio,â Kyvig recalled. âThe 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: âI 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 Hugoâs tornado struck in 2008, he and wife Jill remained on the radio as long as they could but had to abandon the âham shackâ as the storm approached. The tornado did $30,000 damage to their home, including Kyvigâs 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 heâs never met around the world.
âItâs a worldwide network of people enjoying fellowship with other hams,â Kyvig said.
The radio operator answers calls for help in areas of âhealth and welfare,â and was on Centervilleâs first CERT (citizen emergency response team), which is now inactive. He serves as a severe weather spotter too, and gains âinsightsâ as to what is happening around the world by chatting to foreigners.
âWe talk about everything from fishing, to weather and local problems,â he said. âItâs very interesting because you find out so much about people across the world. And itâs not just the personal part but handling messages for help in disasters.â
Heâs 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. âLord knows what theyâre talking about,â Bob said. âI leave the room.â
Ham buffs do have opportunity to meet at events called âeyeball picnics.â 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 donât 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.
âWe could be talking to people the FCC thinks is a bad guy,â he said. âBecause 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.
âThe concept is simple,â he added. âWe 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 masterâs degree from The 3905 Century Club. Itâs not the typical academic degree, but a difficult achievement nonetheless. âThe degree was a challenge,â 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 â20s, 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 thereâs a power outage. He also keeps a mobile 12 volt transmitter that he can use in his truck to chat while heâs 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 heâs not on the radio, Kyvig enjoys making furniture and fixing TVs. He retired from a career in computer operations about five years ago.
When you think about DJs you donât worry about their hearing, but this is a real issue in the music world, they seem to be slow in picking up this issue, probably because the industry can be full of bedroom DJs, that donât consider hearing protection. As the article below says, it interferes with the mixing. This article was originally published on THUMP Canada.Â
I’m waiting to get my hearing tested and I’m scared. Most of my work as a music journalist, along with my social life, has revolved around loud music for more than two decades. While I often wear cheap foam earplugs, I haven’t been as consistent as I should have been, and I’m particularly worried about is the damage I’ve done while DJing.
I was never a famous touring DJ, but spent many years playing long shifts on a weekly basis at Toronto bars, sprinkled with occasional club and warehouse party gigs on larger sound systems. I’ve never worn any hearing protection in the booth, as I found earplugs interfered too much with mixing. Gradually I’ve noticed that I’ve been turning up the monitors over the course of a long night, and the ringing in my ears was taking longer and longer to fade away after each gig. A few years ago, I started to realize I was having trouble keeping up with conversations in situations where there was a lot of background noise.
Then one day that familiar ringing never stopped.
Even though hearing loss caused by loud music is aÂ well-known reality, most working artists view it as an issue they’ll deal with when they’re retired, not aware of the fact that it can often impact artists at the height of their careers.
“I would go home after a gig and my ears would be ringing really badly, and then one day I noticed that they never stopped ringing anymore,” says Toronto house DJ and producerÂ Sydney Blu, who’s been playing regularly since 2000. “Not long after that, I noticed that whenever I’m in a nightclub and someone talks to me in my right ear, I have to stop them and put my left ear to their mouth.”
She eventually got herself fitted for custom musician earplugs, but found she could never get used to DJing while wearing them. Instead, Blu just tries to keep her monitors as quiet as possible, and turns them down completely in-between mixes. “Most of the older DJs that I know all have tinnitus. I wish I had thought about it earlier, and realized how bad it could get.”
There is no way toÂ reverse tinnitusÂ currently, and theÂ treatment options for hearing lossÂ are still in their infancy. For busy DJs who are constantly touring and playing festivals around the world, many don’t notice the ringing in their ears getting worse until it’s too late.
“I think it’s rife in the DJ field,” says NYC house music veteranÂ Roger Sanchez. “A lot of people have tinnitus and they haven’t even identified it. They’re just so accustomed to their ears ringing, and they think it’s just because of their gig the night before. But if you’re playing three or four times a week, your exposure is almost constant. Then when they step back, they realize they have tinnitus.”
Sanchez has been performing for 36 years, and started to experience permanent ringing towards the end of the 90s. Like Blu, he got himself fitted for custom earplugs, and feels they’ve saved him from further damage. However, he admits there was a learning curve when it came to mixing while wearing hearing protection.
“In the beginning, I felt like I couldn’t hear things clearly. It was like someone had put their hands over my ears. It took me a while to acclimate, but what I started noticing was that I could turn my monitors up, but it didn’t sound piercing any more. I also had them put bass bins in a lot of booths, which helped compensate.”
Sanchez says that it’s become much more common in recent years for big name DJs to wear custom earplugs while performing. He finally got tested properly in 2010, and found there was a significant dip in upper range of his hearing around theÂ 800hz range, but was relieved that the loss wasn’t worse. The persistent ringing in his ears is still there though.
“Right now I hear the ringing, but I’ve just become accustomed to it. I don’t notice it when I’m walking on the street, or if I’m not paying attention to it, but the second I quiet everything down, the ringing starts. It’s not too loud, thank god. I think using the filters prevented it from getting to that level. I know some people who have it very loud.”
Custom musician earplugs can cost more than $200, but they’re one of the few options for DJs who need to be able to accurately hear the effect of their EQ tweaks and filtering. The cheap disposable earplugs you can buy at the drugstore will protect your ears the same amount, but change the sound so much that few performers use them.
“A cheap foam earplug might bring the sound down by 25db at one frequency, and 10db at another,” explains Adam Rhodes, the US director of hearing protection companyÂ ACS Custom. “They muffle the sound, because it’s not a true response. You can’t hear anything, it takes away the enjoyment of the experience, so you just end up taking them out. When you’ve got the right filter though, you’re not sacrificing the quality at all: you’re just turning it down.”
ACS works with many of the biggest names in electronic music, from Tiesto to Zedd to Deadmau5. Rhodes says that there’s much more awareness of the issue now, although too often artists come to them after they’ve already done permanent damage. “Pretty much every week we hear someone say they wish they’d heard about this ten years ago. We hear that often,” he says. “I think it’s all about education. We’re at a festival every weekend in the summers, trying to make it as accessible to them as possible.”
Many touring musicians have switched to in-ear monitors in recent years, which block out external sounds, while amplifying what they need to hear. In the electronic music world however, they are far less common, as they require DJs to completely rethink their approach to mixing.
“In-ear monitors haven’t always worked for DJs,” admits Rhodes. “They like to wear the cans over their ears, so they can take them off, and do a mix with one ear covered. There are some DJs who use them though, like Deadmau5. We have one model now that have ambient microphones built in, so that they can still hear the mix. That’s kind of the next level, but it’s still hard to persuade DJs to use them. They’re so used to wearing headphones and it’s almost part of their outfit when they’re performing.”
One artist who has transitioned to in-ear monitors is Dutch DJ and producer Laidback Luke. He started wearing custom earplugs in the early 2000s, after becoming concerned about tinnitus and a growing lack of sensitivity to loud volume levels. Around 2008, he decided to give in-ear monitors a try and has used them ever since.
“I just wasn’t getting the definition I was looking for in DJ monitors. We tried the in-ear monitoring, and I was so happy with the clarity. Even in big halls with lots of reverb, my monitoring would always stay the same,” he says. “It was a revelation to me. I could keep the volume low, and still hear every little detail in the song. I couldn’t hear the crowd anymore, but that just made me work harder to get applause.” It wasn’t until three years ago that he finally got up the courage to get his hearing tested.
Thankfully, it turns out that his early adoption of ear protection had a huge impact, and the results were completely normal. Even the constant ringing and beeping that panicked him early in his career has subsided.
My own ringing isn’t nearly as bad as it was a year ago, but it sure seems loud in the complete silence of the soundproof booth in the downtown Toronto clinic where my hearing is being assessed. I struggle to hear the tones, but feel optimistic that I’m able to notice some of the very high-pitched signals they’re feeding me. However, I’m also noticing that there are long pauses during where I probably should be hearing something.
“Do you work with heavy machinery?” the doctor asks me as he looks at my results, which makes my heart skip a beat. When I explain that I’m around loud music constantly, he tells me that explains what the chart is telling him, and why the highest frequency range of my hearing is still decent.
“It’s not actually too bad. Your left ear has a dip at 1K, but it’s still within the normal range. Your right ear has a much larger dip though, at 4K. You should really get yourself a pair of custom musician earplugs.”
I leave his office feeling relief that my hearing isn’t worse, but embarrassed that it’s taken me this long to take it seriously. Thankfully, it’s not too late for me to stop things from getting worse.
Virtual reality and augmented reality will creep into our lives slowly in the next 10 years, it has so many applications from gaming to business. Motorola have been leading the radio industry for many years and are taking the initiative with this technology, While this will take away the need for CCTV, radios, radio earpieces and headsets, it will add a more immersive, structured way of running events and festivals.
Motorola SolutionsÂ is exploring a future where virtual reality will immerse a public safety command center supervisor in an incident scene. By using a combination of virtual reality and eye-interaction technologies to navigate through video and data feeds from multiple sources, incident responses can be quickly coordinated and information shared widely to help guide officers and protect people at the scene.
Motorola Solutions will show live demonstrations of the virtual command center on Aug. 15-16 at the Association of Public Safety Communications Officials (APCO) 2016, held at the Orange County Convention Center in Orlando, Fla. (booth #1337).
The virtual command center proof of concept uses eye-interaction technology from startup company Eyefluence, a Motorola Solutions Venture Capital investment, to envision the future of public safety.
A look at todayâs smart public safety solutions
Todayâs public safety command centers can integrate the Project 25 (P25) standards-based, interoperableÂ ASTROÂ®Â 25Â land-mobile radio (LMR) network for mission-critical communications with the power of LTE broadband and the latest in smart public safety solutions to turn data into intelligence.
Since 2009, Lake County, Fla. has been using Motorola Solutionsâ ASTRO 25 LMR network as the core network for emergency interoperable communications for several counties across Florida. On Aug. 17, Greg Holcomb, Lake County public safety communications technology manager/E911, will join Motorola Solutions in a managed services panel discussion at APCO entitled âSystems Down: Best Practices for Eliminating this Status from Your Network Performance Logsâ (see all Motorola Solutions presentations at APCO 2016Â here).
âThe Lake County core network and many connected sites on this P25 mission-critical communication system are managed by Motorola Solutions,â said Holcomb. âWith their robust managed services offerings, the company ensures 24×7 availability, reduced risks and maximized performance for our public safety network.â
Motorola Solutions’Â CommandCentralÂ platform provides real-time intelligence throughout all phases of police work â from planning, to operations, to investigations.Â CommandCentral AwareÂ aggregates video from several sources, allowing crime center analysts to view multiple feeds on one screen and share high-definition images of suspects, vehicles, license plate numbers and other critical information to responding officers in real time.
âLaw enforcement agencies have access to data from multiple sources including 9-1-1 calls, live video feeds, social media activity, nationwide databases and more,â said Jim Mears, senior vice president, Motorola Solutions North America Sales. âMotorola Solutionsâ CommandCentral platform captures this information and turns it into real-time intelligence that helps first responders resolve incidents quickly and even prevent them from happening.â
The CommandCentral platform will be showcased at APCO 2016, along with several of the latest mission-critical communication solutions from Motorola Solutionsâ Innovation Design Center in Plantation, Fla. This includes theÂ Si500Â body worn camera andCommandCentral VaultÂ digital management solutions, which automates and streamlines the processing of video from the point of capture to video management and review, and theÂ LEX L10Â LTE handheld device designed for the rigorous demands of real-world, front-line policing.
Introducing new mission-critical solutions at APCO 2016
Motorola Solutions is launching the new APXâ¢ 8500 P25 all-band mobile radio, updated ASTRO 25 network features and the IMPRES 2 energy management system.
APX 8500 P25 all-band mobile radio:Â With Motorola Solutionsâ newÂ APXÂ 8500Â P25 all-band mobile radio, first responders can use a single mobile radio to exchange critical voice and data communications â such as text messages and GPS coordinates â with multiple agencies and jurisdictions operating on different radio bands. Radio updates can be made instantly without interrupting voice communications; the radio does not need to be brought to a shop, saving both time and money. When connected to the Motorola Solutions VML750 LTE vehicle modem (now available globally), the APX 8500 frees up radio channels by offloading data to LTE.
APX Personnel Accountability for ASTRO 25 trunked networks:Â The APX Personnel Accountability solution is now available for ASTRO 25 trunked networks (which enable efficient operation of large systems with a small number of channels) and continues to also be available onÂ ASTRO 25 conventional networks (where users select communication channels).
Commanders using the APX Personnel Accountability solution can automatically perform tactical notifications and streamline roll call processes via a computer. They can automatically account for staff using APX radios at the scene of an incident. If a team needs to evacuate, commanders can instantly alert them through their radios and receive acknowledgements. Commanders can monitor radio battery life, identify radios and receive radio power down indications. If a radio is on the wrong channel, a commander can remotely switch the channel to the right one and ensure the entire team can communicate with each other.
ASTRO 25 Enhanced Geo Select:Â Geo Select provides hands free operation of APX radios when entering a defined region, or geofence, and this feature is now available even if the radio is no longer on the network. When entering a geofence, APX radios can automatically take action such as change channels, alert the user and change power levels. No manual intervention is needed.
ASTRO 25 Over-The-Air radio software updates:Â ASTRO 25 Over-The-Air Programming (OTAP) has been available for radio managers to remotely program APX radios. Now they will also be able to update APX radio software over-the-air for their entire fleet simultaneously over the course of a few days, without disrupting radio function in the field. With this new feature, there is no need to bring radios to the shop for software updates, saving both significant time and money.
IMPRESâ¢ 2 energy system for APX radios:Â The newÂ IMPRES 2Â high-capacity, water-resistant batteries keep APX radios powered longer. When combined with the new IMPRES 2 charger, they deliver 60 percent more charging cycles than traditional lithium-ion batteries. The IMPRES 2 chargerâs enhanced diagnostics provide usage data including a batteryâs ability to hold a charge, letting users know when itâs time to replace it. The multi-unit chargers also feature customizable charging â batteries in service can be charged at 100 percent while those in storage can be partially charged to optimize battery life.
Smart earpieces are the next frontier for the smart generation, we have all seen the earpiece that can translate instantly But that is just the start, as we can see from this article about this Xperia Ear wireless earpiece, it updates you from your phone when you put it in your ear. It wonât be long before we wonât need a smart phone everything will be in our ear.
Sony has revealed its âsmart personal assistantâ that include a bluetooth earpieceÂ will go on sale in November.
At the IFA show in Berlin today, the firm confirmedÂ it will launch this November âstarting in select markets,â although its price has still not been revealed.
The Xperia Ear wireless earpiece can update you with any missed calls or messages as soon as you slot it into your ear.
The firm also showed off aÂ Xperia Agent, a robot measuring just over one foot tall, that also works as a PA.
âIt will navigate you to where you want to go and make your life eye-free and hands-free,â said Sony Mobileâs President and boss, Hiroki Totoki of the âherâ earpiece when it was unveiled at the MWC show earlier in the year.
âIt is also powered by Sonyâs voice technology and will respond to a number of commands.â
The firm says the smart earpiece âis a next-generation wireless ear-piece that brings a new way of communicating, without compromising on enjoying the world around you.â
It reads users information such as your schedule, weather and the latest news to keep you up-to-date on the go.
Powered by Sonyâs voice technology, it responds to verbal commands, so you can ask it to make a call, perform an internet search, dictate a message or navigate to a certain location.
It connects to an Android smartphone via NFC or Bluetooth and talks to a host application, where you can customise settings, including the info you need when you first connect in the morning, touch commands and app notifications.
âIts lightweight and comfortable soft silicone ear-bud is built for continuous wear, with IPX2 water-protection and all-day battery life3,â Sony said.
Itâs available in Graphite Black and the innovative case doubles as a charger, so you can simply pop it in when you need to recharge.
It also unveiled the Xperia Eye, a wearable camera that acts as your personal sidekick, capturing everyday life moments with a 360 degree wide-angle lens.
Unveiled at Mobile World Congress (MWC) in Barcelona, the Xperia Eye can be attached to clothing or worn around the neck.
It forms part of a suite of connected gadgets designed to free people up from their phones.
Sony said the Xperia Eye is âa vision for a personalised assistantâ and joins three other smart gadgets that are connected to a Sony smartphone that acts as a hub, feeding information to them such as notifications.
These are Xperia Agent, Xperia Project and Xperia Ear.
Xperia Agent is a security camera-style device which acts as a home monitoring system, keeping an eye on whatâs going on around it and projecting notifications fed to it from a Sony smartphone onto surfaces around it.
âIt will provide you with useful information, communication assistance and home appliance controls,â Sony said.
Xperia Project projects an interactive interface onto any clear surface, meaning you can manipulate images, webpages and screens you would usually find on your smartphone, onto a hard surface.
Sony claims this projected image will respond to touch, voice and gestures just as someone would interact with your smartphone screen.
The Xperia Ear is a wireless earpiece that will update you with any missed calls or messages as soon as you slot it into your ear.
âIt will navigate you to where you want to go and make your life eye-free and hands-free,â said Sony Mobileâs President and boss, Hiroki Totoki.
âIt is also powered by Sonyâs voice technology and will respond to a number of commands.â
The wearable camera is the first time Sony has shrunk its image sensing and camera technology into such a small device.
If youâre planning a family outing where youâll camp for several days, or if youâre headed for an amusement packed backpacking expedition with friends, you might want to know where to buy walkie talkieÂ 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.co.ukÂ 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 thereâs 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: whatâs the best choice? However, this isnât a very hard decision once you understand where and how youâll use it. Firstly, youâll 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, youâll have to be contented with a frequency fee. On the other hand, unlicensed band walkie talkies attract no fees, but theyâre comparatively low in power plus a limited range thatâs 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 youâre 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 thereâs 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 youâll use your radios strictly indoors or if itâs 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
