A Walkie Talkie is a handheld receiver or portable radio. Walkie talkies come in a pair and they communicate quietly with one another using radio waves, on a single shared frequency band.
Almost all of us grew up with walkie talkies. As children, and especially before the age of mobile phones and technology, we all had a pair and played with them in our gardens.
Walkie talkies have made a comeback. Or maybe they never really went out of style but now theyâre sophisticated.
Each unit is battery powered and has an antenna for sending and receiving radio wave message. There is a transmitter / receiver and a loudspeaker. The loudspeaker doubles up as a microphone. There is a button that you push to talk, pretty much the same way that an intercom works. Some more sophisticated walkie talkies have separate loudspeakers and microphones; it just depends on what you need the walkie talkie for.
Walkie Talkies with noise cancelling headsets
Technology has changed so much and become so much more sophisticated. In the old days, think of the crackles that came with walkie talkies. It was often very difficult to hear what the other person was saying. But a pair of noise cancelling walkie talkie headsets will reduce or remove any unwanted sounds by using active noise control. Note that this is very different from passive headphones which use technique such as soundproofing. Noise cancelling is not soundproofing.
Our worlds are busy and we become bombarded and overwhelmed by everything around us. We need to listen to some things, but we want to cut out others. Noise Cancelling allows us to do this, while still allowing us to listen to the things we want to listen to at the volume we want them.
Pros of a walkie talkie headset?
Remember when we used to listen to music really loud so we could block out all the other external noise? You don’t need to do this anymore. walkie talkie headsets will block out most excess or excessive sound, or the ones you want blocked out anyway. You can now listen to your music at the volume you want, which does not need to be crazy, and the other external sounds (baby crying, man snoring next to you) will be blocked out anyway. Finally, you can listen to and enjoy music in the way you want to enjoy it, at a natural volume. You can hear the fabulous music, have a rich listening experience, and still not be disturbed by chatter around you.
Noise cancelling headphones are fabulous for when you travel or commute. You may be the kind of person who gets on a plane and train and chats to everyone around you. But you may be more solitary and want to sit down and zone out. You can do this easily with a walkie talkie headset. The beauty is that on a plane you wonât hear the noise of the aircraft or its passengers, but you will still hear the safety announcements.
Itâs really easy to work in a noisy environment with noise cancelling headphones. You can focus easily without being disturbed and can make use of any space, productively. You can even go and study your history while at a party or in a restaurant. It is also a good idea to use them at home, while studying for exams or so; they cut out the excess noise and you can focus totally on your work.
Students used to turn up the volume of their earphones in order to cut out the outside worldâ. But with a walkie talkie headset they are finding it is easier to study when music is at a lower volume and when the outside distractions have been eliminated.
Cons to noise cancelling headphones?
There are always cons to everything. Some parents may say they would prefer no headphones at all. They like their children to be available and to engage more and talk more, but we know this is the way of the world. Everyone uses headphones; parents included/ Use them in moderation of course, but still be sociable and take time out in the day, be headphone free, and engage.
Noise cancelling headphones are not very cheap and are in fact possibly even ten times more expensive than ordinary headphones. However, like anything that costs money, they will last for a long time and are super reliable. They may cost more money but will ultimately give a much better noise-free experience.
Lots of research has gone into the design of these special noise cancelling headphones. Each set consists of inner components that cancel out the disturbing external sounds. Ordinary headphones do not have these components, i.e., you cannot cut out the outside sounds. It is quite obvious then, why noise cancelling headphones are more expensive.
These internal components also use up a lot of power. The power can come from internal replaceable batteries or they can be rechargeable. The walkie talkie headset that carry their own power supply means they are heavier than ordinary headphones. Not all sets carry their own power supply. The ones that are rechargeable are lighter, but they can drain the devices they need to plug into for power.
The quality of sound when using a noise cancelling walkie talkie headset can be compromised. It is unusual though and it is only the most sensitive of ears that would pick this up. There have been very few complaints of a tinny almost mechanical sound, but these complaints are few and far between.
Not all , although we did mention this under pros as well. It is never possible to cancel out all external sounds, but we still need to be able to hear police sirens, pilot announcements or the high pitched screaming of your next door neighbor. All every day external sounds though are muffled and definitely much quieter, and the sounds that you don’t need to hear, are gone.
Hytera are truly making huge waves in the two way radio market and thisÂ acquisitionÂ on Motorolas home turf is remarkable. An insider has told us that this tender was won through a lot of hard work and attention to detail. Hytera are growing rapidly, we have heard from one source at EarpieceOnline.co.uk that their Hytera radio earpieces are out selling theirÂ MotorolaÂ equivalentsÂ this year.

This is an excellent story about how hearing protection is sometimes be essential, and when youâre on the shooting range it has to be vital. But it is important to get the right set of headphones that will protect your hearing sufficiently. Lessons can be learnt from this excellent case study.
There is no doubt that we all take our senses of sight, smell, and hearing for granted as long as we are strong and healthy and everything is working well. When we are young we tend to believe that we are indestructible and readily adopt the idea that âit will never happen to me.â Consequently, we can develop some bad habits and be a little loose when it comes to preventative measures for almost anything.
I know because that was my attitude at thirty years old when my eye doctor made a comment in passing that my eyes were perfect, but the chances are I would be needing reading glasses by the time I was 50. I scoffed, but you could almost have set your watch by it because by the time I was in my late 40âs my arms started to get shorter when it came to reading, tying on fishing lures and other things that required scrutiny up close. At 50 I was wearing reading glasses.
Growing up I never bothered too much about wearing ear protection. When I was plinking it was with a .22 rifle that only put out a little noise if you were the shooter so the thought of hearing protections seemed ludicrous. When hunting I do not know if I have ever heard my firearm discharge and beside that unless I was dove hunting I seldom shot too many shots anyway.
The change of heart came when I started shooting on an indoor range, while in the Air Force. I noticed after shooting a few rounds with my .22 caliber, Ruger Single Six that my ears would ring for a while afterward. One night a grizzled old Master Sargent suggested I wear ear protectors or take a chance of damaging my hearing. I took the recommendation to heart and have been wearing them ever since. The result has been that after many years of shooting .22âs, large caliber handguns, rifles and shotguns my hearing is still intact and working well.
Shooting is not the only activity that can cause hearing problem as any loud noise can damage your hearing. The intense vibration caused by loud noises can injure or destroy the hair cells inside the cochlea, so they no longer function to transmit nerve impulses to the brain. If that happens, you will experience hearing changes.
Hearing protection is needed anytime one is exposed to sounds above 80 decibels (dB). Normal human conversation runs about 30 to 35 dB. At its peak level, the sound of a 12-gauge shotgun is about 140 dB. 9mm runs around 159 dB and a .38 special with a six-inch barrel is about 156 dB, a .22 LR pistol with the same length barrel 140, an M-16 is about 154, a .45 ACP pistol is 155, and a .357 Magnum revolver is 164. All of them are around double the safe sound level. Just to be on the safe side I used to wear muff type hearing protectors and usually ear plugs also when on the range.
For range use today there is an array of muff style hearing protectors. The new style that I now use have not only hearing protection, but also hearing enhancement. The controls on each ear can be tuned to match your individual optimum hearing and increase the volume up to eight times normal. So when the range master gives a command or when you are speaking with a companion on the shooting line you can speak in a normal voice and hear them as well or better than without the power muffs. Yet when you shoot the sound activated compression circuit reduces the sound from the shot to a noise reduction rate of 24dB.
This is very important on a shooting range because I have missed range commands in the past from the range master simply because I could not hear them through my hearing protection.
The new muffs I use are from Walkerâs but they offer many other styles in their Game Ear series. These are unlike the muff style protectors as the bulk of the unit fits behind your ear with an earpiece that fits inside your ear, the unit weighs less than one fourth of an ounce and can be used with or without glasses. These too can be fine-tuned to your specific hearing, allow you to turn the volume up to magnify sounds from five to seven times and still reduce the sound of the shots to a rating of 29dB.
The ability to custom tune the devise to your hearing as well as adjust the volume up on these models will enable the hunter to more readily pickup games sounds in the woods. Sounds like a squirrel jumping through the trees or when their belly slaps a tree when they jump from one to another. It will help the hunter pick up the minutest sound of a deer brushing by limbs or the whisper of them walking through leaves or disturbing a rock.
So now there is really no acceptable reason not to wear hearing protector and if you get a good set it may even enhance your chances of bagging some more game.
SO youâre walking down the street and suddenly the music kicks in, you drop to the ground and pull your earphones out of your ears! âwhat just happenedâ you think, then you realise the un-pause on the mp3 has just kicked in and you forgot to turn it down. Well people this will be a problem of the past with these earphones, Now all I need them to do is make coffee. VERY IMPORTAN You can find the original article here
Whatâs been your favorite set this weekend? Or the best new track youâve shared with all of your friends? Well take that track and imagine listening to it in exactly the way your ears want you to.
Meet theÂ EvenÂ earphones, who tune themselves to each personâs particular hearing. At just under $100, they customize the sounds they play to suit your own audio needs. They use their own EarPrint technology that measures how you hear different frequencies, then sets the earphones toÂ play back sound specifically for each ear. As a result, theÂ headphones give you aÂ profile tuned to your own ear (each ear with its own profile).
One of the biggest things that originally drew me to the earphones was the fact that they are not a pre-order campaign â they have physical earbuds available now. The company, whoÂ launched in in June, has sold out batches twice thus far and are continuing to take orders on their website. Luckily, I was able to get my hands on a pair to try out as well.
Iâm pretty picky about the gadgetsÂ I use for audio, as Iâm constantly listening to music â digging for new sets on Soundcloud, reviewing new tracks, jamming outÂ in my own world. Being able to plug in and listen to my own musicÂ isÂ what allows me to focus and, as a result, Iâm very specific about the type of earphones or headphonesÂ I use. That being said, I was overly ecstatic when I was handed a pair of Even earphones to try out.
First, their appearance: the cords are aÂ high-quality string that have a smooth look and feel. The budsÂ look sleek, with a simple black-and-white color scheme â one black, one white, with the EarPrint device hanging at the middle of the cord, meant to dangle at your chest. They donât tangle easily, which makes them easier to carry without having to worry about dealing with knots. Theyâre the type of earphones I wouldnât mind wearing out in public.
Next: the sound test. This is where we meet âSarah,â the soothing female voice that guides you through a number of sounds to test where your hearing level is at. This test was very straightforward â Sarah literally starts by saying âHi, this is really easyâ â and felt very conversational as sheÂ talked you through each noise. Five pieces of music are played for each ear, and youâre required to hit the button once you hear the sound. Though the process takes a little bit longer than Iâd like, itâs seamless.
Overall quality of the listening experience was great. I switched between my Bose over-ear headphones and the Even earphones to test the difference in sound quality and worked to try a few subgenres of electronic music to see how each would sound between both pairs. I started off by listening toÂ Louis The Childâs set from Lollapalooza this yearÂ and instantly found that the vocals were much more emphasized than in my Bose headphones. Next, I moved on toÂ Mikey Lionâs live set from Desert Hearts 2016Â andÂ lovedÂ the emphasis on the bass I was hearing â the Even earphones made it much more of an all-around experience. I then switched over to Troyboiâs tracksÂ Do You?Â andÂ O.G.Â to continue to test this bass theory and, again, Even delivered.
As my hearing is likely damaged based on the amount of festivals and shows Iâve attended over my lifetime, it was much appreciated that the earphones were able to pick up on the frequencies I have more trouble hearing to create the full experience tracks deserve. Interestingly enough, every time I switched back to my Bose headphones to compare, I had to turn the volume down because it came at full blast and was overwhelming â and, when I did, the clarity between vocals and bass was lost. All in all, these babies pack a punch with their sound quality when it comes to electronic music.
Itâs refreshing that these earphonesÂ donât require using an app, since that seems so commonplace nowadays. All of the information that goes into your profile is saved in the little box hanging onto the string, so you can plug them into any device â phone, laptop, iPod, whatever you want â and still have your own profile saved. I found this extremelyÂ helpful, as it meant that I donât have to re-adjust my volume based on what device Iâm using. Beyond that, itâs a refreshing change from listening to sets with friends and having to change the volume based on everyoneâs sensitivities. It makes listening much simpler and, quite frankly, electronic music better. How could you say no to a custom-made, surround-sound system in your own ears?
To get you started, here a few sets, old and new, you may enjoy listening to in the earphones (ok, to be fair, these are sets thatÂ IÂ would want to hear in them):
We all know how important radio communications are and at a time before the internet and even digital communications, governments relied on RF communications that were susceptible to the suns solar storms, if you add that to the cold war nuclear tensions then we could all be living in holes now.
Cold War history isÂ rife with close callsÂ that nearly led to nuclear holocaust.
In September 1983, for example, sunlight reflecting off a patch of clouds fooled a Soviet missile-warning system into detecting the launch of five US intercontinental ballistic missiles that never were. A wary colonel in a bunker ignored the alarm onÂ a 50/50 hunch.
Two months later, US forces staged “Able Archer 83” â a massive nuclear-strike drill on the doorstep of the USSR. Soviet commanders panicked at the show of force and nearly bathed America in thermonuclear energy. Once again, an act of human doubtÂ saved the planet.
Now scientists have one more hair-raising event to add to the books:Â The “Great Storm” of May 1967.
“The storm made its initial mark with a colossal solar radio burst causing radio interference … and near-simultaneous disruptions of dayside radio communication,” a group of atmospheric scientists and military weather service personnel wrote in a new study, published August 9 in the journalSpace Weather.
Hours later, high frequency communications dropped out nearÂ US military installations in and near the ArcticÂ â one of the closest places to station nuclear weapons and launch them at a Cold War-era Soviet Union.
“Such an intense, never-before-observed solar radio burst was interpreted as jamming,” the study authors wrote. “Cold War military commanders viewed full scale jamming of surveillance sensors as a potential act of war.”
A ‘Great Storm’
Earth’s magnetic field protects life on the planet by corralling the sun’s high-energy particles toward the planet’s polar regions.
If the sun happens to launch a cloud of solar particles directly toward Earth during a violent outburst, called a coronal mass ejection, it can triggerÂ powerful geomagnetic storms.
This not only leads to beautiful auroras, but can also scramble wireless communications and disrupt radar systems.
While The Washington Post wrote up a story about the storm as “City Gets Rare Look at Northern Lights,” top US military commanders sounded the alarms in secret.
The Air Weather Service (AWS) â a relatively new branch of the Air Force â had warned military leadership about the possibility of a solar storm, but US commanders believed the Soviet forces were jammingÂ NORADÂ systems designed to detect threatening planes and missiles.
As the Strategic Air Command warmed up the engines of bombers and taxied toward the runway, the decision to go airborne may have been kicked all the way up to the “highest levels of government,” possibly involving President Lyndon B. Johnson.
“Just in time, military space weather forecasters conveyed information about the solar storm’s potential to disrupt radar and radio communications,” according to aÂ press release from the American Geophysical Union. “The planes remained on the ground and the U.S. avoided a potential nuclear weapon exchange with the Soviet Union.”
And this all happened at the peak of nuclear armament â when aÂ record 31,255 nuclear weapons were deployedÂ around the world. (Today there are roughly 7,200Â nuclear armamentsÂ at hand.)
“Had it not been for the fact that we had invested very early on in solar and geomagnetic storm observations and forecasting, the impact [of the storm] likely would have been much greater,” study leader and UCAR atmospheric scientist Delores Knipp said in the release.
After the near miss, the researchers say the military learned to listen to its space weather forecasters, improve its abilities to see another looming “Great Storm,” and avert the first and perhaps final global nuclear exchange.

Closed Back Headphones vs. Open-back Headphones
Open-back headphones have pads which rest on the outer ear. They’re designed such that the outer shell of the ear cup has perforations usually with horizontal cutouts. The Open back headphones design of the ear cup enhances better natural sound because of less coloration as compared to the Closed back headphones.
Closed back headphones have much larger earpads which encircle the ears. They are designed such that there’s a big pad which cups the ears, and it features an insulated outer shell of plastic which covers the ears. The Closed back headphones actually have a very solid outer shell which doesn’t have any sort of perforations such that the outer shell effectively cups/encircles the entire ear. The Closed back headphones are excellent at isolating noise. They block most of the ambient noise, but they’ve a smaller sound stage, which gives the user the perception that the audio/sound is originating from within their head. Closed back headphones also tend to produce much stronger low frequencies as compared to Open back headphones.
Low Impedance vs High Impedance
Headphones normally come in various different impedance levels, such as 8 ohms, 16 ohms and 32 ohms. The power that’s supplied by an audio source may be at varying levels because of a variety of factors including being limited because of being battery powered. Generally, as the impedance of the headphones increases, much more voltage will be required in order to drive it, and the audio loudness of headphones for a particular voltage decreases.
The determination of impedance is usually disregarded by many headphone buyers, however, the truth is it’s one of the most important factors to consider when choosing the best headphones for your particular needs. Impedance is basically just how much power the headphones can put out so that it can overcome resistance to move the headphones’ diaphragm.
Low impedance headphones (that is, less than 25 ohm), usually require little power in order to deliver high audio levels. Low Impedance headphones play well with devices which have weak amplification. These can include; mobile phones, portable music players and various other portable devices. This type of headphones can be used at home and also while jogging with your mobile phone; this is one of the reasons why most of the on-, in-, and over the ear headphones, are low impedance. Low impedance headphones are normally designed to get plugged directly in to a single (one) source, and generates sound more efficiently from a lower level input signal. This headphones tend to be much louder and much more efficient, however, they will also require a much more capable amplifier.
High impedance headphones (25 ohms and above), generally require more power in order to deliver high audio levels. As a result, they’re protected from damages caused by overloading. High impedance headphones are typically designed for studio like applications where there might be multiple phones/devices wired in parallel and receiving input signals from a single source. High impedance headphones are more tolerant of the amplifier limitations, however, they will produce less volume for a particular output level. They are also a little more durable (that is, electronically), however, they require much higher signal levels in order to produce the same level of output level of the low impedance headphones. This type of headphones can be used with a wider range of audio equipment.
Passive Headphones vs. Active Headphones
Passive (noise cancelling) headphones are made of materials which help in blocking out sound waves from the surrounding environment. The same way ear muffs soften the outside noise, so does this type of headphones employ passive noise canceling. This type of headphones are typically used for both professional mixing and monitoring, like in broadcast and recording studios, and such other applications. Passive headphones are basically designed to playback music/audio true to the actual original recording, with minimal, compression, EQ, and such other sound enhancements.
On the other hand, Active headphones use batteries in order to power the built in Digital Signal Processing (also abbreviated as DSP) technology which processes play back for a particular reason, for example, to enhance the bass and the high end. Due to the enhancement of playbacks with sharper high ends and more bass, active headphones are more popular for general listening and listening to music for pleasure. Active noise cancelling headphones are also made of materials which help in blocking out outside noise, however, they take things a step further by making their very own sound waves; the sound waves created mimic the outside noises, but are a mirror image of each other, thus cancels each other out.
Wired Headphones Vs Wireless Headphones
When choosing a pair of headphones, deciding between wireless vs. wired is among one of the most overlooked factors. Wireless headphones might be a more popular choice, however, the wired headphones also have their own set of benefits. Well, that being said, as a general rule of thumb, between wireless headphones and wired headphones, assuming a similar price between the models; the wired headphones usually offer a much better quality. Also, the audio quality may get compromised over Bluetooth.
You can opt for the wireless headphones if you are not much of an audiophile, and you tend to travel a lot. If you really don’t like getting the cables of your headphones getting tangled, or caught while listening to music/audio, then the choice should be rather simple; go for wireless headphones.
You can opt for the wired headphones if you are an audiophile, and you do not necessarily bother with the wireless options unless absolutely essential like using them when traveling, or keeping the headphones as a backup. As aforementioned, the wired headphones are way ahead in terms of output quality as compared to the wireless headphones. You will never have to worry about running out of batteries, unless you happen to opt for wired headphones which cancel noise. In addition, you will never suffer from interference from the other commonly used wireless electronic devices. However, you will need to take good care of the wired headphone cables, or they will eventually break.
Back in December the UK government decided on who and what will drive the new generation of emergency service communications. The ESN (Emergency Services Network) was the result of months of tendering and negotiations. So they decided that EE would manage the network and Motorola would provide the hardware. This article is about the first wave of communication devices that Motorola are planning to use with the ESN.
New innovative solution combines body-worn video camera, radio speaker and microphone with cloud-based data storage and management to create a complete digital evidence management system
At Critical Communications World 2016 (May 31 to June 2 in Amsterdam), Motorola Solutions announces a new combination of body-worn video camera, radio speaker and microphone, along with new, cloud-based, digital evidence management software, which is able to collaborate with TETRA digital two-way radios. The new âSmart Interfaceâ (Si) Si500 Video Speaker Microphone (VSM) is reducing the number of devices that weigh down public safety officers in the field today, while CommandCentral Vault digital evidence management software is providing unparalleled efficiency that saves time and resources.
Public safety agencies today face an increasing demand to capture, store, properly manage and share video evidence. While use of body-worn cameras has widespread and growing acceptance with public safety agencies and the citizens they protect, the massive amounts of data cameras create needs to be managed and stored, oftentimes incurring significant costs. With its new solution, Motorola Solutions tackles all of these challenges and offers an end-to-end solution that can be used with existing TETRA radio equipment. Public safety agencies are provided with a seamless experience from video capture in the field to back office storage and content management that helps them simplify workflows and reduce administrative overheads.
âIn Europe Middle East and Africa (EMEA), TETRA digital radio technology has become a standard for mission-critical communications,â said Steven Young, vice president TETRA devices at Motorola Solutions. âThis is why we have developed a body-worn video solution that collaborates with TETRA radios. The Si500 is transforming digital evidence management by integrating our best microphone into a body-worn camera and combining it with a content management system thatÂ´s unmatched in its ease-of-use.â
Sight and Sound Simplified
Both body-worn camera and remote radio speaker microphone, the compact Si500 VSM is a unique interface that extends the mission-critical performance of Motorola Solutions TETRA digital two-way radios. The lightweight compact design includes innovative features to meet the needs of first responders:
Digital Evidence Management Revolutionized
The digital evidence management solution includes the cloud-based CommandCentral Vault software application to securely store, manage and share digital evidence. With an expansive base storage capacity and integration with computer aided dispatch and records management systems, CommandCentral Vault is designed to make digital evidence management easy and affordable. The digital evidence management software also:
Many business and factories are very well aware of their legal obligations when it comes to occupational deafness, and here in the UK we have the Control of Noise at Work Regulations 2006. Many of the headsets that are listed on Headsetonline.co.uk are designed exactly for these types of industries, with their experience they are a leader in radio headsets and hearing protection equipment. But as the article below explains the protection has to personalised to everyone, so as to make sure that the individual is catered for and protected adequately. The original source of this article can be found here.
Hearing loss is preventable. Why, then, is it still so common? NIOSH notes that occupational hearing loss is one of the most common work-related illnesses in the United States. And according to OSHA, approximately 30 million people in the United States are exposed to hazardous noise on the job.
âNoise-induced hearing loss is generally a gradual and painless process, so many workers donât consider it a hazard â¦ until itâs too late,â said Katie Mielcarek, marketing manager for Cleveland-based Gateway Safety Inc. Mielcarek went on to say that workers donât wear hearing protection for many reasons, including discomfort, poor fit and problems with compliance monitoring and trouble inserting earplugs.
Here, industry insiders discuss whatâs new and offer advice on hearing protection.
âElectronic muffs contain the latest technology designed to protect against environments with impulse noises,â said Eric Moreno, market manager for Cranberry Township, PA-based MSA. âThe technology amplifies weak sounds while compressing dangerous noises to a predetermined safe level of 82 dB or lower.â Moreno said this allows face-to-face communication and lets workers hear important sounds, such as warning signals.
Gary Klee, product manager for above-the-neck products at Latham, NY-based Protective Industrial Products Inc., pointed to a âlevel-dependent systemâ available with electronic earmuffs. This system has microphones in both ear cups to help limit sounds reproduced through the internal speakers to a safe level, which âallows communication with others while remaining protected against impulsive or hazardous noise,â Klee said.
Ricardo Allamelou, COO for Miami Lakes, FL-based Cotral Lab Inc., said providing every worker with the exact same type of hearing protection doesnât make sense. âThe protection has to be personalized since overprotection is as dangerous as no protection at all,â he said.
According to Moreno, âOverprotecting can actually increase the danger to a personâs life because this can hinder their ability to hear relevant noises such as warning signals, moving vehicles, other workers, etc.â To reduce the chance of overprotecting, Moreno recommends thoroughly understanding the level of noise in every area of the workplace to determine what level of protection each area needs.
Additionally, be sure your hearing protection is independently, third-party tested to verify noise reduction ratings, Mielcarek said. âThis helps communicate quality in an industry where many manufacturers simply mark their products with a standard or a rating, without the testing to back it up.â
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. 2 way radio onlineÂ 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.co.uk
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 2wayradionline
Patrick Macnee, the actor best known for his work on TVs The Avengers has passed away. He was 93 years old.
Macnee was born in London, England in 1922. His father trained racehorses and was noted for his keen fashion sense, whilst his mother was a niece of the Earl of Huntingdon (which may even have made Patrick a descendent of Robin Hood!). However, such privileged beginnings proved to be only deceptively comfortable for the young Macnee, who saw his father drink and gamble away the family fortune, before leaving the country for India, while Macnee lived with his mother and her Lesbian lover Uncle Evelyn Spottswood. The pair attempted to dress the young boy up as a girl, but settled for a kilt instead, which was how Macnee was dressed every day until he was eleven years old.
Spottswood paid for Macnees schooling, which included boarding school from the age of five, a preparatory school (where he acted alongside a young Christopher Lee in a production of Shakespeares Henry V) and ultimately a spell at Eton, where he joined the schools dramatic society. Eventually however, Macnee was quietly expelled from the school after he instigated a gambling ring and was then caught selling erotic photography and whiskey to his fellow pupils.
By this time though, he had already been bitten by the acting bug and so decided to pursue a career in the performing arts.
Before he could make his West End debut, the young actor was called up for National Service. It was 1942 and World War 2 was in full swing. He began his military career in the Navy as an ordinary seaman, before progressing to sub-lieutenant. Fortunately, a nasty bout of bronchitis caused Macnee to miss the D-Day landings, where the ship he was serving aboard was destroyed and the entire crew killed. He was ashamed of not being present at the battle for the rest of his life. Macnee was demobilized in 1946 with the final rank of lieutenant.
Patrick Macnee learned his craft via a number of small roles, appearing in The Life and Death of colonel Blimp in 1943 and portraying a Spear Carrier in Lawrence Oliviers 1948 production of Hamlet (alongside an uncredited Christopher Lee), amongst other assorted roles. However, as the years passed and his big break failed to arrive, Macnee became depressed and frustrated by his lack of progress.
Eventually, he decided to leave the United Kingdom for Canada, making the difficult decision to leave his wife and two children behind in the process. He arrived in Toronto with just Â£10 in his pocket. In Canada, Macnees eccentric Englishness made him a genuine novelty and his career began to pick up somewhat. He explored producing and, as an actor, appeared in over 30 televised plays, before finally hearing about a new television series in development called The Avengers.
In The Avengers, Macnee played the unflappable British secret agent John Steed from 1961 to 1969, before reprising the role for 1976 – 77s The New Avengers. Both the series and the character would become an iconic part of British popular culture, creating a legacy that endures to this day. The show made Macnee an international star and proved to be his finest hour as an actor.
The character of John Steed first appeared in The Avengers pilot episode Hot Snow (1961). Here, he was depicted as being an assistant to Dr. David Keel. When Ian Hendry, who had played Dr. Keel, quit the show later that year, Steed became the central character and was partnered with a series of crime fighting accomplices, namely Dr. Martin King (Jon Rollason), Venus Smith (Julie Stevens) and finally Cathy Gale (played by future Bond girl Honor Blackman).
As the series progressed, Macnee extensively re-designed Steeds wardrobe, furnishing his character with the now iconic look of bowler hat, Saville Row suit and gentlemans umbrella. Of course, these garments came to be tricked out with various spy gadgets as the series went on.
It was Steeds debonair, quintessentially British wardrobe that helped the show to become so successful both at home and overseas. In fact, the clothes were so iconic that in France The Avengers is known as Chapeau Melon et Bottes de Cuir â Bowler Hat and Leather Boots.
Macnee also decided early on that Steed should never carry a gun. In later interviews he stated that he was sick of firearms after experiencing âa war in which Id seen most of my friends blown to piecesâ.
Besides, a pimped-out brolly is waaaaay cooler.
In 1965, Steed was paired with his most iconic partner (and best, but Im biased since she was my childhood crush) Mrs. Emma Peel. Portrayed by Diana Rigg, Mrs. Peel (designed to have man appeal â hence the name) was smart, self-assured and supremely confident. In a unique twist, Peel often acted as Steeds muscle, being by far the more physical of the two characters. Although he frequently rescued her from harm, their relationship was truly a partnership of equals, making Mrs. Peel, secret agent, martial artist and chemistry genius, a genuine pioneer among female heroines. Macnee was always proud of the strong, positive female characters that were so prominently featured in The Avengers.
Rigg left the series in 1968 and promptly followed her predecessor into the James Bond franchise, while Macnee was partnered with Linda Thorsons Tara King until the series demise a year later in 1969.
ITV revived the Avengers concept in 1976 and Macnee starred alongside Joanna Lumley (Purdy) and Gareth Hunt (Gambit). The show ran for two series, but, despite a positive reception, was scrapped in 1977 due to financial problems.
Away from The Avengers, Macnee appeared in the James Bond film A View to a Kill (1985) and the classic Rock n Roll mocumentary This Is Spinal Tap (1984), where he portrayed Sir Dennis Eton-Hogg, the somewhat sanctimonious president of Taps record company. He also played Dr. George Waggner in 1981s cult favourite The Howling.
In 1998, Hollywood made a disastrous attempt to revive The Avengers. The movie starred Ralph Fiennes, Uma Thurman and Sean Connery and Patrick leant his support in the form of a voice cameo. However, without the twinkle, wit and class of the original John Steed, the idea was doomed to failure.
Finding himself in the enviable position of being a pop culture icon, Macnee was asked to appear in music videos for The Pretenders and Oasis amongst others. He also contributed vocals to a novelty single Kinky Boots with Honor Blackman that was issued three times, the first in 1964, the second in 1983 and the third in 1990, where it eventually became a top 3 hit.
As a television actor, Macnee appeared in such memorable shows as The Twilight Zone, Rawhide, Colombo, Frasier, Battlestar Galactica, Murder, She Wrote, The Love Boat, Magnum P.I, Diagnosis Murder, The Littlest Hobo, Alfred Hitchcock Presents and many others. He even played Dr. Watson alongside Christopher Lees Sherlock Holmes.
In later life, Macnee became a nudist. After an infancy spent in a dress, a childhood in a kilt and an adulthood in the finest suits money can buy, why not spend an old age in the nip? For a style icon that brought the suave and stylish John Steed to life with effortless grace, charm and virility, one supposes that it must have felt like the next logical step.
R.I.P Patrick, you will be sorely missed.
