Is it Worth Buying a Cheap Two Way Radio?

It depends on what you want to do with it. Two-way radio technology is actually fairly simple. The basic mechanics of a radio don’t really change much from unit to unit, or from manufacturer to manufacturer.

Some radios may have flashier features (which you can decide for yourself if you really need) and others might have extra functions, such as the ability to switch between analogue and digital, but, to a large extent, a two way radio is a two-way radio.

A few of the features advertised (and no doubt added to the overall price) will do you no good whatsoever. For example, a radio claiming to have a range of 25-30 miles is simply lying to you. The average radio has a range of between 1 and 2 miles. Some are a little stronger that this, most are not.

Some radios advertise being waterproof or water resistant (some even come with built-in weather warnings) and, if you’re planning on using the radio in more outdoor conditions, then this is definitely a plus and worth spending money on.

Now, as for the tech itself, your radio’s power output is an important factor, but if you are only having a bit of fun, you likely wouldn’t need to go over 0.5 watts (and thus end up applying to Ofcom for a radio license). Generally, FRS (Family Radio Service) radios are cheapest and they are fine for a bit of fun, but GMRS (General Mobile Radio Service) radios, although they cost a little extra, are worth it if you need to transmit a stronger signal over a longer distance.

Other features, such as a built-in LED torch, a stopwatch, built-in alarms and/or a fancy light-up screen are only worth spending out on if you have a use in mind for them. Otherwise, it might be cheaper to simply provide torches and stopwatches to your staff if they require them. That’s a judgment call.

An emergency button, however, is always a good idea. The same is true for a ‘privacy’ function, especially if you are using your radio in an area with lots of other radio signals bouncing about.

Finally, we come to the idea of brand name. Certain products (we could name a particular headphone brand endorsed by a certain rapper, but we won’t) are all about selling the ‘in thing’ with a flashy logo, a branded image, a HUGE markup and little else to offer the customer. Radios are not this way, if you buy a trusted brand (such as Motorola), you can be assured of getting a quality product. In this instance, spending a little more for an established name can definitely pay off.

Essentially, if you want a two-way radio for business use, then it is worth spending out that little extra. However, if you only want one for hobby use, then you can pick one from the lower end of the market and not worry too much about it. Extra features are what add to the price more than anything else and it is entirely up to you to decide if you need them or not.

Whats’s a Covert Earpiece?

With very little information on the internet about earpiece’s, it is very rare when we get a chance to re post, with permission, an article from this industry.

A covert earpiece is a miniature earpiece worn by an individual while being effectively hidden from plain view. It operates as a radio accessory in times when a user does not want other people to know she or he is communicating with others using radio earbuds. Also known as an invisible earpiece or a surveillance earpiece, a covert earpiece is often worn by government agents, corporate security personnel, undercover law enforcement officers and corporate as well as government spies.

covert earpiece

While many occupations require the use of a radio headset for communication, a covert earpiece is primarily used in instances where communication is of an extremely private and sensitive nature. This is common in cases of private security details and surveillance projects. Sometimes people also use a covert earpiece to defraud businesses and others. Examples of such instances would include someone using an invisible earpiece to cheat on an exam or to defraud a casino by receiving remote information while playing a game.

On-air television personalities may also use a covert earpiece, which is not distracting to viewers, but allows the person to hear relevant feedback from producers and engineers in order to make sure a taping or live appearance flows smoothly. Individuals may also wear a covert earpiece when making a public speech. By doing so, the speaker can receive important cues or changes in a speech without the audience even being aware that communication is taking place between someone located behind the scenes and the individual delivering the speech.

Some covert earpieces are accompanied by a discreet microphone, which enables two-way communication. These are commonly used by security forces with a need for such communication, particularly during surveillance operations. These types of accessories are not only convenient because they feature hands-free operation, but also because they allow undercover security forces to blend in with crowds without having to use a visible walkie-talkie system of communication.

A covert earpiece does not contain any visible wires and is designed to fit inside the ear without being noticeable to the general public. Some devices are even designed to fit on a pair of eyeglasses while amplifying sound inside a person’s ear. An inductive wire is sometimes worn around the person’s neck, but is covered by clothing so as not to be discovered by onlookers. This wire is not connected to the covert earpiece, but connects to a separate radio device that helps modulate sound.

A Personal experience of a doorman using an earpiece

Communication, as you all know is so vital in all aspects of our lives. In any security set up, whether you are protecting high profile personnel or you are carrying out a covert operation or even just working as a doorman, one thing has been clear to me; that communication between you and your team or your bosses is vital as well in ensuring that things run smoothly. However, communication may be interrupted depending on the working environment. Other days you may find yourself in rather noisy crowds. When this happens, it is important that you choose the right communication device and accessories that will make your work easier. An earpiece has been one of my favorite working gadgets for a very long time.

Why Do I like the doorman earpiece

Ever since I started using doorman radio earpiece, things have really been smooth for me and my work. An earpiece makes it practically simple to communicate and coordinate things between me and my colleagues together with my employers. Among the things that make these earpieces interesting and fun to work with include:

· They are en suite with excellent quality Kevlar cabling and strain relief that are long lasting which protects them from spoiling when pushed to the extreme.

· Doorman earpieces have excellent audio quality that easily neutralise any surrounding noise allowing an operative to hear everything said to them in a very clear and loud manner. In addition, most of them are fitted with microphones making it easier for a two way communication.

· They are compatible with a lot of gadgets and even more comforting is the fact they can easily be replaced at a very affordable price.

· Unlike many electronic gadgets, doorman earpiece is pretty easier to configure and use. It will interest you to know that no skill or knowledge is required to set it up and make it work.

What to look for when purchasing an earpiece

Technology keeps changing from time to time, and so are needs. As a doorman/bouncer, there are specific things you ought to look for when purchasing a doorman earpiece. These are features that are needs to be compatible, rather friendly with your working environment and your preference as a person. For instance, if your work is based in a noisy environment like say a club, you will need very fine audio quality sets that fit properly in your ear preventing any interruption from outside. In addition, you may consider the cords strength if you are working in a hostile environment where people keep getting in fights.

Compatibility is another important thing to look for in a earpiece. Note that there are earpieces that are compatible with nearly all types of gadgets while others are restricted to only specified gadgets. For flexibility be keen to purchase an earpiece is works with wide range of gadgets. Finally, the cost is equally as important. Contrary to what many people believe, expensive doesn’t always mean better, the same way inexpensive doesn’t necessarily mean something is of poor quality. Compare features and always go for one that looks a bit refined for a better experience.

Conclusion

It is clear that every one working in security should absolutely have a set of doorman earpieces. It is not only efficient, but also profoundly valuable to this line of work. Take your time, and determine what will work for and get the earpiece that will make your work easier.

The Doctor Who Earpiece Experiment

The short answer is ‘no’. Apple Earpods debuted in 2012, a full six years after the ‘Doctor Who’ episode ‘Rise of the Cybermen’ first aired.

Within the context of the series, the Earpod devices were designed as a metaphor for society’s perceived over-reliance on portable technology in the 21st century. The name ‘Earpod’ was a play on words, meant to superficially sound like the word ‘iPod’.

In addition, the fictional earpieces were mainly utilized as a way to re-package classic Doctor Who antagonists the Cybermen for a new audience (who may have been unfamiliar with them following the gap between the show’s cancellation in 1989 and its subsequent reintroduction in 2005). Variations on the Earpod device are also utilized in later episodes from the same series (in particular, ‘Army of Ghosts’).

Whilst it is something of a stretch to imagine that nobody at Apple has ever watched ‘Doctor Who’, the use of the name did not seem to affect the American computer firm’s decision to create and market their own brand of ‘Earpod’, in 2012.

doctor who earpiece

In terms of legality, it seems reasonable to assume that ‘Doctor Who’ created the brand name for satiric purposes, rather than to create an entirely fictional brand/product (such as The Simpson’s ‘Duff Beer’).

Had Apple simply adopted a product name already owned by the BBC, there may have been a legal scuffle between the two corporations, but since BBC’s product was obviously intended as a wry commentary or, at most, a satirical send-up of existing technology (in particular technology made and marketed by Apple), then it is highly doubtful that there was any friction at all.

Apple’s Earpods (which, as far as we know, have never caused anybody to be turned into a cybernetic creature hell-bent on universal obliteration) are available at a fairly affordable price (the Apple site lists them at £25.00 before P&P), but do not have a reputation for being one of the company’s better products. In a particularly scathing review, TechRadar wrote that,

“The tinkle at the high-end is certainly better than before, and there’s improved bass as well. So they’re more than good enough if sound quality is not something you are bothered about. If you’re going to be buying an iPhone 5 or one of the new iPods, you’ll be getting some marginally better earphones than you might have expected, so that’s a good thing. But for anyone thinking of buying these things separately for £25/$30 – forget it. That price is utterly ludicrous. For that money you could bag yourself a decent pair of Sennheisers – low end ones admittedly – but they would still be head and shoulders better than the Apple EarPods. In fact, we challenge you to find a pair of £25 earphones on Amazon that sound worse than this – you won’t be able to”.

All things considered, the Earpod is a pretty basic variation on the standard Apple headphones. It is not even marginally related to the mind-controlling earpieces utilized by the Cybermen. At least, as far as we know…

My Other Computer’s a TARDIS: Virtual Reality Makes Time Travel Possible

A new virtual form of ‘time travel’ could be employed to help victims of traumatic experiences overcome their ordeals.

In a computer generated ‘virtual world’, participants can move about and interact with their environment in a similar manner to how they would in the real world.

Professor Mars are unassailably cool, told BBC news that,

“In virtual reality, the brain’s low level perceptual system does not distinguish between the virtual and the real world; the brain takes what it sees and hears in a surrounding environment as given (…) Therefore, if they had an experience with the illusion of time travel, there is implicit learning that the past is mutable, that is: ‘my own past decisions don’t matter because they’re changeable’.”

The latest study, published in the journal ‘Frontiers in Psychology’ featured a scenario wherein 32 test subjects witnessed a brutal multiple murder. In the virtual scenario, (presumably designed to induce both a moral dilemma and a controllable level of trauma) a man opened fire in a crowded art gallery and ‘killed’ five people.

Gunman starts shooting in the virtual world

The group then elected to ‘go back in time’ and attempt to prevent the murders.

Half of the group were not allowed to change their actions and simply had to repeat the event, the other half were allowed to intervene, but knew that doing so would result in the death of one person. Essentially, these people had to face the ethical dilemma of forfeiting the life of that one person in order to save five people.

Unsurprisingly, most of the test group chose to sacrifice the one life.

In terms of practical applications, this equipment is expected to allow people suffering with PTSD (Post Traumatic Stress Disorder) and other psychological issues to confront their previous actions/inactions and better understand them in order to forgive themselves and move on.

Such technology might also be applied to prisoners undergoing therapy and/or rehabilitation, or even survivors of violent assaults.

Dr. Friedman Doron of the Sammy Ofer School of Communications in Israel, who worked as the study’s lead author, said that, for now, his team’s work is the closest people can get to actual time travel. He told BBC news,

“Highly immersive virtual reality is very visceral. People hide behind the desk when they get shot. Some of the subjects duck down. It’s the best thing we can do for time travel until the physicists do their job and come up with a time machine. For now this is the closest thing.”

What Does Two Way Radio Mean?

A two way radio is one that can transmit and receive. It is also called a transceiver. The two way radio definition encompasses most of the wireless or cellular systems. Portable devices which use the two way radio system are called walkie talkies or handie-talkies. The transmitter on a two way radio device is turned on by pressing a push-to-talk button. Pushing this button sets you free to start talking through the device. There is normally another person on the other end of the conversation, or a group of people who have devices which use the two way radio system.

The 2 way radio technology is one of the earliest wireless network technologies. Despite the fact that there are countless other ways of wireless communication due to innovation, the two way radio system is still viable and used by people to widen their communication range.

It is mainly used due to the following two main advantaged:

Communication is Instant

The two way radio system enables instant communication. Within a fraction of a second after pushing the push-to-talk button, you would be able to pass on your messages . This has been made possible by a quick call set-up time integrated in this technology. The reliance of organizations on the two way radio system is founded on the fact that the device enables instant communication.

Group Communication is Possible With This Technology

This is a distinct feature of the two way radio technology. The capability of this system to create a scenario where a whole group communicates even from distances apart is also called “group call”. It is very efficient in that one caller is able to convey a message to up to thousands of other users at the same time. Not one user receives his/ her message later than the others in a group call. The conveyor of the message does not need to repeat himself/ herself so that the message is heard by everyone in the group communicating. Very little radio frequency channel resources are used during the group communication, meaning that it is not a way that utilizes so much of an organization’s resources.

Benefits of a Two Way Radio System of Communication

All wireless technology systems of communication have their advantages and disadvantages. Organizations or groups have their preferences in regards to how they conduct their day-to-day businesses.

A two way radio system of communication is superior to other systems of wireless communication due to the following key reasons:

o It is suitable for people who are mobile hence are rarely together to carry out their duties and responsibilities close to each other.

o It is suitable for communicating among a group of people.

o Communication using the two way radio system is instant.

The aspect of a two way radio system of instant communication enables emergencies to be handled pretty fast. A situation that requires urgent attention can be attended to as fast as possible. A cellular phone would be a great option for communication of emergencies, just that, they take time as the person on the other end of the call has got to receive first so that the message is conveyed. The few seconds or possibly even a minute as the phone rings could create an avenue for the situation to worsen. A two way radio system only requires you to push a button and then convey the message straight-up, as long as the radio frequency channels are available. In the event of congestion on the radio frequency channels, the two way radio system is designed to overcome this and create a priority in the event of an emergency. This feature is not available to other technologies of the wireless system.

Conclusion

The two way radio system is very efficient and economical. Making phonecalls to more than 5 members of a particular group would be pretty expensive as compared to conveying messages through a two way radio system. It would also take time to call one member after the other, a situation that would not arise with the two way radio technology.

Why are Mario & Luigi known as the Mario Brothers?

 

For some people of my generation, Mario and Luigi games have been around for our entire lives. I’m not sure we would know what to do without a regular supply of Mario and Luigi games. Those would see it as the end of the world. For the majority of us, less crazy, people, Mario and Luigi games mark the passing of your years, ageing to perfection sort of a fine wine.

 

It is a fact, however, that you won’t learn much from Mario and Luigi games. Actually, when I had my first Italian training (aged around eleven) I did my very best Mario impersonation when delivering my lines to the remainder of the class. To his eternal credit, my tutor never once chided me with the order “do it again, and this time be less of a berk!” Continue reading
