New Smart Cast Lenovo Phone Projects a image or Video on to Walls

Oh, now THIS is cool. A new phone unveiled by Chinese corporation Lenovo (makers of the Ideapad tablet, amongst others), will be able to project interactive objects, such as virtual keyboards or piano keys onto almost any flat surface.

The ‘Smart Cast’ phone (which could have been branded better, it has to be said) will also be able to project videos and photographic content onto walls, desks or any other flat surface, allowing the user to share videos (and even potentially screen movies) with multiple viewers.

The phone is able to project a fully functional replica of its own touch screen, or even a full-size computer keyboard if desired.

Despite being utterly tiny (34mm x 26mm x 5mm), the phone’s laser projector does not need focussing in order to project far larger images onto walls, desks, or anywhere else you might need to project an image (and for all you nerd lings aiming on creating a pocket Bat-Signal, forget it. I got there first!).

The projector itself can also be manually moved into at least one other position, which ensures that the projection quality should always be first rate.

…It even has a motorbike style kickstand to keep it upright when you’re using the virtual keyboard. How cool is that?

Justifiably proud of their new creation, Lenovo hired Chinese concert pianist Lang Lang to play the phone’s virtual piano as projected on the desk in front of him. I suppose they could afford to, as it was recently announced that their profits are up 20% from last year.

Of course, projector phones have been explored in the past, usually without success. The Samsung Galaxy Beam, released in 2012, was a failure of Star Trek: Into Darkness proportions (the joke being in the ‘beam me up’ area – in case you missed that) and the technology is notoriously hard to use. Still, perhaps this time somebody has finally gotten it right? Time will tell…

Sadly for us Brits, the Smart cast phone seems unlikely to be released here in the UK, so for us, it’s all a moot point in the end.

The Smart Cast phone was officially unveiled at Lenovo’s Tech World conference in Beijing, China, an event that also saw the debut of a new smartwatch, which has a ‘public’ and ‘private’ mode for some reason (all I can imagine it would be useful for is if somebody asked you the time whilst you were watching porn – at which point, keeping the screen on your wrist would defeat the object somewhat anyway).

It is open to interpretation as to whether or not the Smart Cast phone will be a stroke of consumer electronics genius or a costly failure, but for now, the early buzz certainly looks intriguing and you can pretty much guarantee that various engineering bigwigs employed by other developers will be following its progress with interest.

Are Your Headphones Causing Your Acne?

We all take reasonable care of our stuff, particularly when we wear it, we wash our clothes regularly, we shower, more than twice a week! but when was the last time you cleaned your headphones? they might not look dirty, or do they? this article seemingly does.

Headphones are a necessity for the modern music-lover or phone user but your gadgets could also be taking a negative toll on your skin.

Some things in life never seem to last as long as we want them to: Your last paycheck, free cookies, or (perhaps most disappointing of all), clear skin are all relatable examples. Sure, we know that there are tons of prescribed, over-the-counter, and even some go-to natural ingredients that can treat an annoying blemish in a flash, but wouldn’t it be less frustrating to know why our pimples are, well, popping up in the first place?

While genetics and hormones play a huge role, there are certain sneaky, everyday habits that could be irritating your skin too. Like coveting those beloved gadgets of yours.

For instance, think about how your headphones go everywhere with you—school, work, the subway, the gym—and you slide them on without giving it a second thought. Cranking up the music is totally therapeutic (and yes, great for drowning out an annoying sibling), but it turns out if you’re seeing spots on your temples and jaw line, the headphones you use for your daily jam sessions to Taylor Swift might be the culprit for recurring breakouts.

“Wearing over-the-ear headphones is a perfect setup for causing an increase of acne breakouts and skin infections,” says dermatologist and Simple advisory board member Dr. Debra Luftman. “This is especially the case when you wear them during and after a workout, or if you keep them on for long periods of time. Sweat and moisture collect on and around the headphones, compressing the skin and therefore encouraging bacteria and yeast to multiply.” Gross, but true.

Luckily, a blemish-free complexion doesn’t mean retiring your giant pair of Beats or new Frends headphones for good. To keep them gunk-free, Dr. Luftman recommends giving them a daily rubdown with a makeup remover wipe. (Simple’s Cleansing Facial Wipes are so easy to toss in your bag!) Then, remember to use another wipe to clean the areas around your ears, hairline, and jaw before the next time you toss your headphones on again.

If you find that your headphones get discolored or grimy particularly often, you can also keep a stash of anti-bacterial cloths handy in your purse or backpack. Feel free to pick these up during your next drugstore run. Just be sure to let the earphones dry completely before using them again. The same bacteria that develops from sweat and moisture, can build up from any dampness that stems from your cleansing tools. Come on, putting whatever you’re listening to on pause for 10 minutes isn’t too much to ask now, is it?

Dealing with acne is never fun, but preventing it with these simple tips is music to our ears—literally!

Twelfth Doctor To Battle Vikings (And Other Series 9-Related Rumours)

Just a few short weeks after series 8 of the long-running sci-fi show garnered a Craft Award at the BAFTAs (for ‘Deep Breath’s excellent T-Rex sequences), shooting is already under way for Block 3 (that’s episodes 5 6, in case you were wondering) of Series 9. Phew! Don’t these guys ever take a break?

According to www.doctorwhotv.co.uk, series 9 will see everybody’s favourite Time Lord and his trusty companion having a Viking-themed adventure, guest starring Game of Thrones actress Maisie Williams. Cast and crew have begun filming at Cosmeston Medieval Village, and leaked on-set photos appear to show crewmembers hard at work building period-specific boats. Other leaked info points to a showdown between The Doctor and the Norse God Odin. Should be fun.

The village will also be the setting for the brand-new monster that was officially unveiled by the BBC last week. Looking like a giant Warhammer figure brought magically to life, the monster may (or may not) be called The Cyclone and the teaser photos already have online fans buzzing.

Meanwhile, other on-set photos (leaked by Twitter user Amberlabamba) appear to show star Peter Capaldi in a new outfit, specifically, a pair of Tartan trousers that knowingly remind us of Twelve’s innate Scottishness, whilst also recalling some of the outfits worn by Second Doctor Patrick Troughton.

…He’s keeping the Doc Martens, though.

The costume change is also interesting because Capaldi’s initial series 8 outfit, a stylish, scaled back Crombie coat (designed specifically with cosplay in mind), also recalled an outfit worn by Jon Pertwee’s Third Doctor during the 1970’s. It certainly looks like the BBC costume department are taking a bit of inspiration from the show’s early days. Its all good, just as long as he leaves the six-foot scarf at home – some things aren’t meant to be touched!

…And that goes TRIPLE for any Technicolor dream coats that the costume department might be planning to unleash on us.

In other Who news, it appears that director Hettie MacDonald, best known by Whovians for her sterling work on the Tenth Doctor episode Blink, will be returning to direct a couple of U.N.I.T-related episodes entitled The Magician’s Apprentice and The Witch’s Familiar, which are set to act as a two-part series’ opener. The adventure will probably feature the return of Jemma Redgrave as Kate Stewart, daughter of the legendary Brigadier Lethbridge-Stewart.

Other cast members announced (or rumoured) for series 9 guest slots are Game of Thrones and Ripper Street actor Paul Kaye, comedian Rufus Hound, The Royal Shakespeare Company’s Kelly Hunter (who may or may not be reprising her role as The Shadow Architect from Series 4’s The Stolen Earth) and Clare Higgins, who recently appeared in the Eighth Doctor mini-episode The Night of The Doctor as The High Priestess of The Karn Sisterhood.

Michelle Gomez will also return as Missy – the female incarnation of The Master, as seen throughout series 8.

A particularly juicy rumour (apparently started by The Daily Mirror) has the series returning The Doctor to the Dalek homeworld Skaro, whereupon the Time Lord must contemplate whether or not to murder his nemesis Davros, creator of The Daleks, during childhood. The episode, if indeed it is an episode at all, would therefore re-tread philosophical ground first walked during Terry Nation’s classic Fourth Doctor serial Genesis of the Daleks.

The story may also pick up on the as-yet unused Davros origin story written by former series boss Russell T. Davies, which was cut from series four’s The Stolen Earth/Journeys End two-parter (it can be read in Davies’ Doctor Who companion book The Writers Tale). If this is the case, then this proposed episode might also explain the return of Kelly Hunter to the Whoniverse, for obvious reasons.

Of course, you can never trust the rumour mill too wantonly, but if the idea of a series that features The Sisterhood of Karn, The Shadow Proclamation, Davros, The Master and Odin doesn’t float your (long)boat, then, quite frankly, I’m not entirely sure why you read this far…

New Technology May Double Radio Frequency Data Capacity

A team of Columbia Engineering researchers has invented a technology—full-duplex radio integrated circuits (ICs)—that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Up to now, this has been thought to be impossible: transmitters and receivers either work at different times or at the same time but at different frequencies. The Columbia team, led by Electrical Engineering Associate Professor Harish Krishnaswamy, is the first to demonstrate an IC that can accomplish this. The researchers presented their work at the International Solid-State Circuits Conference (ISSCC) in San Francisco on February 25.

CoSMIC (Columbia high-Speed and Mm-wave IC) Lab full-duplex transceiver IC that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio

“This is a game-changer,” says Krishnaswamy, director of the Columbia high-Speed and Mm-wave IC (CoSMIC) Lab. “By leveraging our new technology, networks can effectively double the frequency spectrum resources available for devices like smartphones and tablets.”

In the era of Big Data, the current frequency spectrum crisis is one of the biggest challenges researchers are grappling with and it is clear that today’s wireless networks will not be able to support tomorrow’s data deluge. Today’s standards, such as 4G/LTE, already support 40 different frequency bands, and there is no space left at radio frequencies for future expansion. At the same time, the grand challenge of the next-generation 5G network is to increase the data capacity by 1,000 times.

So the ability to have a transmitter and receiver re-use the same frequency has the potential to immediately double the data capacity of today’s networks. Krishnaswamy notes that other research groups and startup companies have demonstrated the theoretical feasibility of simultaneous transmission and reception at the same frequency, but no one has yet been able to build tiny nanoscale ICs with this capability.

“Our work is the first to demonstrate an IC that can receive and transmit simultaneously,” he says. “Doing this in an IC is critical if we are to have widespread impact and bring this functionality to handheld devices such as cellular handsets, mobile devices such as tablets for WiFi, and in cellular and WiFi base stations to support full duplex communications.”

The biggest challenge the team faced with full duplex was canceling the transmitter’s echo. Imagine that you are trying to listen to someone whisper from far away while at the same time someone else is yelling while standing next to you. If you can cancel the echo of the person yelling, you can hear the other person whispering.

“If everyone could do this, everyone could talk and listen at the same time, and conversations would take half the amount of time and resources as they take right now,” explains Jin Zhou, Krishnaswamy’s PhD student and the paper’s lead author. “Transmitter echo or ‘self-interference’ cancellation has been a fundamental challenge, especially when performed in a tiny nanoscale IC, and we have found a way to solve that challenge.”

Krishnaswamy and Zhou plan next to test a number of full-duplex nodes to understand what the gains are at the network level. “We are working closely with Electrical Engineering Associate Professor Gil Zussman and his PhD student Jelena Marasevic, who are network theory experts here at Columbia Engineering,” Krishnaswamy adds. “It will be very exciting if we are indeed able to deliver the promised performance gains.”

This work was funded by the DARPA RF-FPGA program

Thankyou to columbia.edu for the tireless research, this really is an exciting invention, the possibilities if this can be brought to our industry are unbelievable.

In Your Dreams: Bloke Dreams About Winning The Lottery, Actually Manages It …But Then Has To Give Half Of It Away…

Back in 2012, Fatih Ozcan, a waiter working at the Kucukkoylu Turkish restaurant in York, apparently experienced a prophetic dream which involved him holding huge bundles of cash in both hands, whilst his boss, Hayati Kucokkoylu (either the restaurant is named after him or its an amazing coincidence) was standing in front of him.

Mr. Ozcan interpreted this dream as meaning that, if he played the lottery with his boss’ money, he’d win huge bundles of cash.

…Well, he was half right.

At work the next day, Mr. Ozcan pestered his boss to buy a few ‘Euromillions’ tickets, using money from the till. The boss eventually relented, suggested some numbers and gave him some cash.

…Amazingly, Ozcan later checked his ticket to find that he had won a Million quid.

When Fatih told Hayati of his fortunes, the boss decreed that all of the money was, in fact, his by right, as his money had paid for the majority of the tickets. Ozcan, for his part, was having none of it, and a major falling out occurred between the two men.

Eventually, the argument ended up going to court, where a judge (with apparently more sense than either man combined), decreed that the winnings should be shared 50/50 between the man that had supplied the ticket and the man that had paid for it.

Sounds fair, right? I mean both men still get a £500,000 payday out of it.

In summary, the waiter had the dream, stumped up a little cash and picked a few numbers. The restaurant manager donated the most cash (the princely sum of £9) and also picked a few numbers himself.

It really isn’t rocket science. 50/50 seems pretty fair to me…

Apparently that wasn’t the end of the debacle, though, as Kucukkoylu appealed the decision and took the issue to the London Civil Appeals Court, in the hopes of walking away with the full Million.

This month, after three years of legal wrangling, yet another judge told him to ‘bugger off and stop being so bloody greedy’ (albeit probably using more fancy language than that). The judge then declared that the fairest course of action was (you guessed it) to split the money 50/50, which pretty much any reasonable person would have already done anyway.

According to Kucukkoylu, he chose the numbers and paid for the ticket and thus, the money should rightly be his, however, without his employee having the dream in the first place, he never would have bought a ticket.

The really pathetic part of this story is that neither man appears to be happy with getting a £500,000 payday – and thus both saw fit to fight over it in court for three years, presumably spending loads on their legal fees.

…Seriously, where’s the logic?

Its hard to decide whether these men are simply greedy and stupid, or just stupid and greedy. Either way, it isn’t good.

As for the (presumably now fired) waiter – let’s just hope any dreams about seven fat customers devouring seven lean ones turn out to simply be a case of eating too much cheese before bed!

British Screen Icon Richard Attenborough Passes Away, Aged 90

British actor, director and screen legend Lord Richard Attenborough passed away last August, he was 90 years old.

The iconic performer, known for a plethora of memorable film roles over a career spanning an impressive six decades, leaves behind a majestic legacy. What follows is an overview of Attenborough’s film work, both as an actor and a director and, after that, a few words about his contributions outside of cinema.

Beginning his career in the 1940’s, the young actor started out in numerous stage plays before attending The Royal Academy of Dramatic Art (RADA), which he would later serve as president. His early film roles included the Noel Coward directed wartime film ‘In Which We Serve’ (1942), which starred John Mills, ‘A Matter of Life and Death’ starring David Niven (1946) and the original film version of ‘London Belongs To Me’ with Alastair Sim (1948).

Lord Attenborough’s big break came in 1947, when he starred as unscrupulous gang leader Pinkie Brown in the film adaptation of Graham Greene’s novel ‘Brighton Rock’ (which also stars future ‘Doctor Who’ actor William Hartnell). Attenborough’s portrayal was nothing short of mesmerizing in its coldness and cruelty and, by 1949, he was considered to be among the most popular British actors of the day.

Throughout the 1950’s, Attenborough starred in war films such as ‘Dunkirk’ – again with John Mills (1958) and comedies like ‘Private’s Progress’ (1956), he also dazzled as Stoker Snipe in the 1950 film adaptation of ‘Morning Departure’, a highly moving piece about a submarine crew stranded at the bottom of the sea, which also starred John Mills.

In 1960, Attenborough portrayed factory worker Tom Curtis in ‘The Angry Silence’, a British ‘kitchen sink’ movie that saw his character refuse to join his fellow workers on strike as himself and his family dealt with the consequences. He also appeared in the classic crime drama ‘The League of Gentleman’ in the same year.

In 1963, Attenborough starred in ‘The Great Escape’ playing Bartlett ‘Big X’ alongside an all-star cast that included Steve McQueen, James Garner, Donald Pleasence, Charles Bronson and James Coburn.

1965’s Oscar nominated ‘The Flight Of The Phoenix’ saw him playing alongside Hollywood screen legend James Stewart. In 1967, Attenborough portrayed Albert Blossom in the musical film ‘Doctor Dolittle’ and, in 1969, he directed his first feature, the musical ‘Oh, What A Lovely War!’

In 1971, Attenborough performed one of his most memorable roles as the serial killer John Christie, acting alongside John Hurt and Judy Geeson in ‘10 Rillington Place’. He was reluctant to take the part at first, but appears to have done so in order to take a stand against capital punishment.

In 1975, he starred alongside John Wayne in ‘Brannigan’. In 1977, he directed ‘A Bridge Too Far’, a war story that starred Sean Connery, Michael Caine, Gene Hackman, James Caan and Anthony Hopkins.

In 1981, Attenborough completed a true labour of love and his most noted work as a director, the epic biopic ‘Gandhi’, starring Ben Kingsley. The film earned Attenborough two Academy Awards, one for directing and one for producing. In 1987, he directed Denzel Washington in ‘Cry Freedom’, which celebrated the life of anti-Apartheid activist Steve Biko. He would next produce and direct a biopic in 1992, directing Robert Downey, Jr, Marissa Tomei, Dan Akroyd and Geraldine Chaplin in ‘Chaplin’, a film depicting the life of influential movie star Charlie Chaplin.

Attenborough’s two most famous late career roles occurred within one year of each other. In 1993, he portrayed impresario John Hammond in Steven Spielberg’s ‘Jurassic Park’ (a role he would reprise in the 1997 sequel ‘The Lost World: Jurassic Park’) and in 1994, he joyously appeared as Father Christmas in the re-make of ‘Miracle on 34th Street’, both roles won Attenborough critical acclaim, as well as an entire generation of new fans. In 1998, he appeared as Baron William Cecil in ‘Elizabeth’, an historical drama also starring Cate Blanchett, Christopher Eccleston and Geoffrey Rush, which focussed on the reign of Queen Elizabeth I.

Attenborough directed his last film, ‘Closing The Ring’ in 2007 and gave his final acting performance in 2004, lending his voice to the film ‘Tres En El Camino’.

Away from acting, Lord Attenborough was active in politics; he was appointed as a life peer (as Baron Attenborough) in 1993 and chose to sit on the Labour party benches at The House of Lords. He was a vocal opponent of South African apartheid and a lifelong advocate of racial equality. In 1983, he was awarded the Martin Luther King, Jr. Non-violence Peace Prize by the Martin Luther King, Jr. Centre For Non-violent Social Change.

A passionate advocate of education at all levels, Attenborough served as Chancellor of the University of Sussex for 10 years (from 1998 until 2008) and he was a patron of University College, Leicester, where his father had served as principal.

He also worked tirelessly on behalf of several charities, including The Muscular Dystrophy Campaign, The Richard Attenborough Fellowship Fund (which also aims to fund research into neuromuscular conditions) and UNICEF, for whom he served as Goodwill Ambassador and donated many of the proceeds from ‘Gandhi’ to. From ‘Gandhi’ alone, he raised in excess of a Million Dollars for the charity.

Lord Attenborough received a CBE (Commander of The British Empire) in 1967 and was fully knighted in 1976. From 1969 – 1982, Attenborough, a dedicated football fan, served as the director of Chelsea Football Club. Between 1993 and 2008, he was also the club’s Honorary Vice President.

Richard Attenborough’s career was truly groundbreaking in every sense of the word. He was unquestionably one of the greatest actors of all time as well as a man of moral courage and noble spirit. As an artist, philanthropist, educator and man of conscience, this world will be much poorer without him.

How to be a better headphone listener

When you’re listening to speakers the sound comes from “over there,” but with headphones where is the sound? A lot depends on the recording and the headphones. With mono recordings the sound is centered inside your head, with stereo the sound picture is more complicated. Vocals, or any sound mixed to appear centered between the left and right channels, will be inside your head, like a mono recording. The sounds over to the left and right might come from next to your ears.

Listening over one of the better open-back full-size headphones, the sound might feel like it’s surrounding you. You’re in the middle of the sound field, or it might come from slightly above your head. The headphones melt away and you are one with the music. Sometimes when I’m watching a movie I forget the headphones. The sound isn’t over there, it’s all around me; I’m in the middle of a sound “bubble.”

I’m not suggesting that headphones can ever mimic what we hear from speakers. Headphones can’t do that, but the downside to speakers is they can never be heard directly; the speakers’ sound is combined with the room’s reflections, reverberations, and other forms of acoustic interference. With headphones the sound “couples” directly to your ears, so you have a far more intimate connection to the music.

With full-size over-the-ear headphones, the contours of your outer ears direct the sound to your inner ears in the same way sound is heard from speakers. In-ear headphones “bypass” the outer ear and produce a more direct connection to the recording. With purely acoustic music, the sound over headphones takes on what I call a microphone perspective, you hear what the mics “heard.”

That’s not the case with electronic music since no microphones were used to make the recording. Even so, I find lots of electronica sounds amazing, and some of the best albums were mixed to produce out-of-head stereo imaging. Listen for depth, does the sound seem very close to your ears or further away? Recordings vary a lot in their stereo imaging, but the more closely you listen, the more aware you will be of spatial cues in headphone listening. Try some of Brian Eno’s ambient albums like “On Land” and “Apollo” to hear what I’m talking about.

To get started, relax and focus on the sound. Your surroundings should be fairly quiet, close your eyes, and sink into the music. After a few minutes the separate left, center, right stereo perspectives should fall away, and your head will feel like it’s in the center of an expansive sound field.

Share your thoughts on spatial headphone listening below.

We found this excellent article here and as you can see it give us valuable information on why headphones aren’t better than speakers, but if you don’t want your neighbors complaining or your family moaning, then you’ll have to wait for the technology to come up with perfect acoustic sound.

New report shares details about the military communications market analysis, size, share, trends,growth and forecasts to 2020

This originally was posted on this site, Military communications always lead the way to other communications. When this market grows, the knock-on-effect is huge for other communication industries.

The global military communications market is expected to grow over the forecast period on account of growing emphasis on providing data-centric and network-centric communications. Rapid adoption of new satellite communications platforms such as Advanced Extremely High Frequency (AEHF) and US-based Mobile User Objective System (MUOS) provides protected communications capabilities for strategic command and tactical warfare operating on various platforms.

Additionally, various communication technologies such as high frequency services and software-embedded radio systems Ka band in order to limit the bandwidth limitations are some of the emerging trends in the military communications market.

The report “Military Communications Market Analysis, Market Size, Application Analysis, Regional Outlook, Competitive Strategies And Forecasts, 2014 To 2020” is available now to Grand View Researchcustomers and can also be purchased directly at

http://www.grandviewresearch.com/industry-analysis/military-communications-market

Considering the rise in demand of handheld software defined radios such as mobile radio, joint tactical radio and tetra radio systems is expected to favorably impact military communications market growth over the forecast period. The military is poised to replace and modernize aging equipments and utilize virtually unlimited IP peer-to-peer connections for embedded systems.

However, multiple standards in devices, financial constraints towards procurement and interoperability issues are the few factors that may challenge market growth through the forecast period.

North America featured among the highest adopters of military communications in 2013 and is expected to remain a key market throughout the forecast period. Adoption of latest data links and mobile satellite technologies are the factors attributable for regional market growth.

The U.S. government is expected to secure commercial capacity due to lack of appropriate military satellite systems. The Asia Pacific regional market is expected to witness significant growth over the forecast period.

Key military communications industry participants include Rockwell Collins, Northrop Grumman, BAE Systems, Alcatel-Lucent, Lockheed Martin, Harris Corporation, Thales Group and L-3 Communication.

How Do You Choose a Good Two Way Radio?

Choosing a good two-way radio is relatively easy. In fact, the vast majority of radios are good in the sense that they will do their specified job to a reasonable standard.

With the majority of two-ways, you don’t need to worry about operating systems (like you would with tablet PCs) or compatibility issues* (like you would with games consoles). All you really need to worry about, in fact, is what you want to use your radio for; this is by far the most important question you need to ask yourself if you’re ever buying a walkie-talkie or two-way radio.

If you’re just looking for a way to keep track of the kids on your next cruise, or you want something to add a bit of fun to your next outdoor excursion, then all you really need to do is find a trusted brand and buy a medium-priced model. It’s as simple as that. However, if you’re a businessperson and looking to buy a radio with a license, then you need to be a bit more careful. In that respect, you definitely want a trusted brand and you definitely want to consult a specialist before you invest in your equipment.

If you happen to fall somewhere in the cracks between these two examples, we’ve prepared a fact sheet (of sorts) for you.

  • There are Four Main Types of Two-Way Radio

GMRS (General Mobile Radio Service) – Is a higher-powered radio, popular for its reliability and versatility. GMRS is the most common choice among users.

FRS (Family Radio Service) – Is usually more of a basic model, lower powered, but generally cost-effective.

MURS (Multi-Use Radio Service) – Is an unlicensed radio that only has a limited capacity. MURS radios are not a particularly popular choice, although they do have their adherents.

And finally,

CB  (Citizen’s Band) – It is called different things in different countries, but CB is a personal service and is a popular choice, however it does require a long antenna. Good for drivers, though.

  • Wattage is Important

No, we’re not talking about that Italian-sounding hybrid of a bluebottle fly and Cyril Sneer from the Star Wars prequels here; wattage is the measurement of watts, as in power output. Wattage is important in radios because it affects licensing. In the UK, for example, radios that have a power output greater than 0.5 watts require a license to use.

It is also important to note that any radio, no matter the power output, will automatically downgrade to a half watt when operating on FRS-specific channels.

  • Keep Signal Coverage in Mind at all Times

Two-way radio manufacturers do a lot of lying and exaggerating about the range of their products. Their claims almost never take into account the signal interference caused by objects in the way, natural obstacles, atmospheric conditions and a plethora of other variables.

On average, the actual signal coverage for any given radio is between one and two miles. CB radios can communicate over longer distances, but those extra long antennas can make them tough to carry around!

  • Privacy Codes are Useful Things

If you’re using your radio in a busy area (i.e. where there are lots of other radio signals bouncing around), you will probably find that the available channels get used up pretty quickly. However, a radio that provides CTCSS will offer a privacy code function that allows you to subdivide your channels by creating a combination of channel and code, this will allow you to better communicate with others, even if the available channels are full.

It should be noted, however, that this function does not make your conversation private; it just reduces the levels of other signals in the area that your device may be intercepting.

Ocean-Going Enterprise Sets Sail Next Year

At the time of writing, we know more about the surface of Mars than we do about the delicate complexities of our terrestrial oceans.

However, next year, a daring and innovative new project is seeking to change all that.

Sea Orbiter, referred to be some as the “starship Enterprise for the water” will be a new type of ocean-going research vessel, a moving laboratory that will hopefully allow Human scientists better access to the world’s oceans than ever before.

Designed by French architect Jaques Rougerie, Sea Orbiter will allow scientists to study everything from underwater archaeological sites to the migration patterns of marine life. It is also expected to extensively map the ocean floors beneath it and to allow divers to work continually on deeper dives than ever before.

Diving to a depth greater than 50 meters or so can cause decompression illness (DCI) and the only way to traverse this obstacle is via saturation diving, which involves prolonged immersion in hyperbaric pressure chambers. Aboard the Sea Orbiter, however, the entire bottom deck will feature hyperbaric pressure levels so that divers can regularly dive to greater depths, but still enjoy a comfortable standard of living when out of the water.

Theoretically, this means that divers will be able to reach depths of up to 100 metres, day after day, simply by remaining in Sea Orbiter’s bottom deck. Also, because the researchers will be diving via a special bay on the underside of the craft, they will be unencumbered by obstacles like bad weather and lack of daylight. In fact, due to this advancement, Sea Orbiter is expected to give researchers unprecedented access to as-yet unknown deep-sea creatures that are only observable at night.

Technology wise, the design appears to have been influenced by the International Space Station (ISS), another innovative project that allowed researchers to reside in their chosen location for long periods of time, something that is always a great boon to scientific research.

Sea Orbiter will also boast mini, remote-operated submarines, as well as a manned submersible capable of reaching depths up to 1,000 metres and an unmanned drone that will be capable of venturing an astonishing 6,000 metres below sea level.

The design of the craft itself is also equally innovative; in fact, the word genius could be applied with little/no hyperbole present. Basically, the craft’s tall, conical shape will render it almost impossible to tip, allowing Sea Orbiter to brave even the most violent ocean storm and emerge unscathed.

In fact, Sea Orbiter is far more stable than most other seafaring vessels. The saucer section in the middle of the craft, and the keel directly below it, are both far denser than seawater itself, which would normally be enough for it to sink like a stone, however, the upper portion of the vessel is designed to be exceptionally buoyant and will only be fashioned from the lightest possible materials, meaning that although two thirds of Sea Orbiter will be perpetually submerged, the vessel itself should never actually capsize or sink.

If Sea Orbiter is successful, this design is expected to become the model for a great many future ships.

Solar and wind power will keep Sea Orbiter’s engines running, with biofuel on standby for use as needed. This means that Sea Orbiter will be one of the greenest post-industrial vessels ever to sail the oceans of the world and, once again, could become a valuable prototype for the oceangoing vessels of the future.

Heavily influenced by the works of Jules Verne and the pioneering naturalist work of filmmaker and explorer Jaques Cousteau, Jaques Rougerie has designed underwater environments for much of his career, even participating in a World Record setting 71-day stint under water. His work to date has included sub aquatic museums and laboratories and glass bottom research vessels.

He has also created workable designs for underwater habitats such as houses and even entire villages.

Construction of the Sea Orbiter is expected to be completed by 2016, but the project’s success still hinges on funding. To date, the French government has provided most of the development money, but the project has also been backed by numerous corporate sponsors and even a public crowd-funding campaign.

If Sea Orbiter’s initial mission is successful, Rougerie and his team are planning to build an entire fleet of Sea Orbiters, which could potentially make their collective task the most comprehensive study of the Earth’s oceans that has ever been undertaken.

In the Early Years: Technology improved for Oneonta police in 1935

Criminals in 1935 would not find Oneonta to be a “pushover” town when it came to law enforcement.

“The Oneonta Police department is preparing to meet the modern gangster on even ground,” The Oneonta Star reported on Monday, Jan. 21, that year. “In the near future, Chief Frank N. Horton announced yesterday, the department will be equipped with a sub-machine gun and a two-way radio-telephone service.”

 These were state-of-the-art technology upgrades for the time and Oneonta appeared to be proud of them, approved by Common Council in the 1935 budget and said to “bring Oneonta’s Police department on a par with other cities in the state, and will materially aid in preventing crime.”

Officers were ready to be trained to use the machine gun, which could fire a 50-shot drum in three seconds, a rate of 800 shots per minute. It weighed nine pounds loaded, so the weapon could be used with one hand like an ordinary revolver for single-shot fire.

To the best of my knowledge, there was never a time or crime in that era that required such firepower in Oneonta. The other new crime fighting tool, the two-way radio, was handy and useful.

By April, the radio equipment had arrived and been installed at police headquarters (then found at the Oneonta Municipal Building, today’s 242 Main St.), as well as the two “prowl” cars used on the streets. Tests were made all over the city and outside the limits, and all transmissions were strong and clear.

Prior to this new technology, The Star reported that officers had to watch for a red light at the top of the municipal building, indicating an emergency was in progress. Instead of awaiting the arrival of a prowl car to pick up the emergency information at headquarters and go, officers could now be dispatched and head to the scene immediately.

Another advance in police work in Oneonta came in March 1935. The department sought supplies used for fingerprinting individuals who wanted to have their fingerprints on file for personal identification purposes.

“Several months ago the department of Justice advocated national fingerprinting,” said M.L. Thomas, a fingerprint expert in the department. “Many Oneontans responded and their records are now on file at Washington, D.C.” It appears the program was tried earlier and was now becoming a permanent part of Oneonta’s police work.

Outreach to young people was part of crime prevention in 1935, just as it is today. On Thursday, Feb. 14, Police Attorney Joseph P. Molinari was a guest speaker at Oneonta High School.

“Crime does not pay and the life of a gangster is short,” Molinari told the students, himself a 1919 graduate of OHS. He pointed out the short careers of John Dillinger, “Pretty Boy” Floyd and “Baby Face” Nelson, stating that “these criminals could never have enjoyed life on their ill-gotten gains, as their luck could not go on forever. In the end they were killed and society was avenged.”

Molinari was in his early career at the time in Oneonta. It was only about a month later, Thursday, March 7, when Molinari announced he was seeking the post of Otsego County district attorney, a job he was elected to. In 1943, Molinari became Otsego County judge, and in 1951 New York’s Sixth Judicial District Supreme Court justice.

While police work was becoming more high-tech in 1935, the routine tasks still needed to be done, which many area residents of 2015 might identify with.

“Stop does not mean slow,” Chief Horton declared on March 25 while announcing that motorists must observe the various stop signs about the city. Police opened a campaign that day to compel motorists to observe the signs and had issued four summonses to drivers failing to stop. Those drivers were set to appear before Judge Frank C. Huntington in city court.

Interestingly, the signs were triangular in shape and made of iron, but the article in The Star didn’t tell what the color was at the time.

On Monday: The region went in front of the cameras for production of “Susquehanna Stories.”

Mark Simonson is Historian of Oneonta City, Twice a week he writes for the thedailystar.com, including this article. What he outlines in this article is more about Two way radios, but also early 20th century crime prevention techniques. 

Lost Copy Of Shakespeare’s First Folio Discovered

A lost copy of Shakespeare’s First Folio has been discovered in Northern France.

The First Folio is the name commonly given to the 1623 collection entitled Mr. William Shakespeares Comedies, Histories Tragedies. The book contains 36 plays, a great many of which had never been published prior to 1623, which makes The First Folio an extremely important document, as it represents the only original source for all subsequent printings/performances of many of Shakespeare’s works, such as The Tempest, The Comedy of Errors, The Taming of The Shrew, Twelfth Night and Julius Caesar.

Counting this new addition, there are only 233 first edition copies of this book left in the world, and each have small textual variations that shed new light on Shakespeare’s writing style, creative process and (possibly) his personal life.

The book was discovered in the public library of Saint-Omer, a small town near Calais. Prior to this, it had been held in a Jesuit college in the town. It was moved to the library following The French Revolution, which ended in 1799.

In addition to being a major literary event in its own right, the discovery of the book has sparked new debates as to The Bard’s religious affiliation.

For over 150 years, some scholars have suggested that Shakespeare had links to secret Catholic sects that were outlawed (and severely punished) in the 16th and early 17th centuries.

Elizabethan England was officially a Protestant country and Catholics were brutally suppressed under this regime. Proponents of this theory cite examples in Shakespeare’s writing (in particular King Richard The Second) and the presence of the mysterious William Shakeshafte at the home (and later in the last will and testament) of Alexander Hoghton, a known underground Catholic.

This previously unknown First Folio is thought to have made its way to France in the possession of Edward Scarisbrick, a well-known English Catholic who is believed to have studied at Saint-Omer in the 1630’s. Scarisbrick was known to go by the name Nevill – and this book is inscribed with the same name.

The Jesuit College that originally owned the book sheltered Catholic exiles and also trained Englishmen who wished to become priests. Today, the institution still exists, although it has been relocated to Lancashire.

Other works of Shakespeare have also been discovered in the Jesuit College at Douai, Northern France.

Of course, this evidence alone merely proves that English exiles enjoyed reading Shakespeare. As Dr. Martin Wiggins, a senior fellow at the Shakespeare Institute in Stratford-Upon-Avon told The Independent, “He was admired and studied by English Catholics. We already knew that. Now we have more evidence. That doesn’t mean that Shakespeare was himself a Catholic sympathiser,”

The book will be put on display in Saint-Omer as part of an exhibition of old English texts, something that is expected to draw tourism from interested parties.

Dr. Wiggins has also suggested that the copy, which has been annotated with stage directions by an unknown party, probably represents the earliest known school production of Shakespeare.

The Hytera Radios are starting to take some of the digital market from Motorola, what makes them so good?

The PD782, PD785 and PD702 Hytera radios are affordable, as well as being easy to use and providing high quality audio. This is a good combination when it comes to two-way radios, a technology that, by definition, needs to be durable, easily replaceable and effortlessly useable in case of emergency.

The parent company, Hytera, have been operating since 1993 and in that time they have developed a strong reputation as an industry leader. In short, they are in the process of cultivating a trusted international brand. Hytera are an emerging brand with a considerable track record for producing quality technology at premium prices.

Another likely source of Hytera’s recent success is the effectiveness of the Hytera earpiece. The Hytera multi-pin earpiece is designed for use with the PD702 and PD782 radio models. It features excellent playback, as well as being solid and durable. This Hytera earpiece is available for around £25.00 and is a professional level model, proving highly effective for many modern surveillance exercises.

Returning to the two-way radio discussion, Hytera radios include a number of advanced features, including a robust design, as well as a full colour LCD display, something that is a rarity in today’s market. There are also a high number of messaging options.

The PD785 is IP57 rated. This means that it can even be completely submerged for up to 30 minutes without obtaining any significant damage. It can also switch between analogue and digital mode and features full digital encryption.

Hytera have received a boost in sales because they have created a series of products that are up-to-date, hardwearing and professional. Two-way radios need to be reliable as a matter of fact, which is why these products are selling so well.

New Sighting Suggests That Extinct Tasmanian Tigers May Yet Live

The Thylacine, an odd, chimera-esque carnivore native to Tasmania, was officially declared extinct in 1986. By that time, no one had seen a live one in 40 years, so it seemed reasonable enough to conclude that a virulent, century-long concoction of wholly barbarous (yet officially sanctioned) hunting methods, disease, deforestation and competition from other predators had wiped the creature from the face of the earth.

However, that may not actually be the case, as recent sightings, including one reported in January of this year, seem to attest.

So convincing are such regular sightings to scientists, cryptozoologists and other interested parties, that a new expedition was launched at around the same time, with the hope of finally capturing proof of the animals long-rumoured survival.

An elusive predator last seen alive in the mid 1930’s, the thylacine, colloquially known as the Tasmanian tiger, has captured the hearts, minds and imaginations of conservationists, explorers, cryptozoologists and, just possibly, a handful of lucky eyewitnesses, for three successive generations.

Dog-like in both size and form, but with an oddly angular head, an enormous gape and chocolate brown stripes running across its tail and back, the thylacine was Tasmania’s apex predator. It was the marsupial equivalent of a wolf, or wild dog (an example of what biologists call convergent evolution) and it existed in Australia and Tasmania for around 23 million years.

The last officially recognised wild Thylacine was shot and killed by a farmer named Wilf Batty in 1930. Six years later, Benjamin, the last captive specimen kept in Hobart zoo, died from a cruel combination of neglect and exposure.

Derided as a pest and a sheep stealer, the extermination of these beautiful, shy and enigmatic twilight hunters was seen, at the time, as a positive step towards the taming of the Tasmanian wilderness.

However, by the time the creature’s numbers had almost completely diminished (if not actually expired entirely), it had become the first poster-child for conservation, an idea practically unheard of before the early 20th century. The Tasmanian tiger was even among was the first animals to be classified as an endangered species.

Concordantly, there is a suggestion that a collection of individuals were shipped over to the Australian mainland and secretly released into the wild there, as an act of conservation.

However, despite the aforementioned declaration of the thylacine’s extinction, evidence occasionally comes to light which suggests that rumours of the Tasmanian tiger’s death may be somewhat exaggerated.

In South Australia, 1973, a very compelling piece of footage was taken on 8mm film stock. The footage appears to show a thylacine running across a rural campsite. The gait and running style are entirely unlike a dog or dingo’s and the animal’s lithe, slender form and bony, tapering tail, potentially offer us a tantalising glimpse of a creature that just may have survived extinction.

In 1985, yet more photographic evidence was offered, this time by Australian Aboriginal tracker Kevin Cameron, who photographed what appears to be a thylacine digging in the ground behind a rock.

In 1982, Parks and Wildlife Service researcher Hans Naarding was gifted with an opportunity to observe a thylacine up close for several minutes, even going as far as to count the stripes across its back (12, in case you wondered). A similar account, also filed by a Parks and Wildlife Service employee, emerged in 1995.

Eyewitness accounts of the creature are both numerous and, for the most part, highly consistent. Although some reports are obviously mistaken accounts of dogs afflicted with mange, or even foxes, others still are surprisingly credible.

The most recent sighting of this incredibly rare creature occurred in January of 2014. It was reported to the Thylacine Research Unit (T.R.U), via the organization’s official website.

The eyewitness, named as Jeremy by the site, revealed that he had seen a 40-50CM tall creature that was about the same length as a small dog (defined as 1metre), whilst out walking in the Landsborough area of Queensland, Australia, not far from the Dularcha National Park. According to Jeremy, the creature had light, sandy coloured skin and faint stripes across its back and tail.

Jeremy says, “As I watched it from the side angle, I saw its head appear and thought, oh its a wallaby, but as it emerged I saw it was on four legs, so thought it was a wild dog. But as it went away into the next thick bush, I noticed light coloured stripes at the rear near its tail”.

Once the animal had retreated into a more heavily forested area, Jeremy decided to “let it be” and tell his friends about what he’d witnessed. Apparently, Jeremy’s girlfriend later revealed that she had also seen the creature in the area.

Emphatic that neither of them had seen a dog, or a dingo, Jeremy searched exhaustively online for any kind of striped, dog-like marsupial, but came up empty handed. There was only one logical conclusion.

Proponents of the thylacine’s continued survival often argue that sightings are increasing because the animal’s population may be enjoying a recovery. It has been estimated that if a breeding population of tigers did survive the 1930’s extinction, that it would take them a reasonably long time to return to sufficient numbers. If that is indeed the case, then 70+ years ought to do nicely.

Hopefully, it should now start to get easier to spot, and conclusively document, a living, breathing 21st century thylacine.

TURTLE BEACH ELITE 800 REVIEW

Turtle Beach’s Elite 800 wireless headset for PlayStation 4 screams “flagship.” It’s a gorgeous piece of kit, all shiny black with lush earpads and rounded edges. Set the free-standing headset on its charge base, which doubles as the wireless transmitter, and it’s an eye-catching addition to an entertainment center. Pop ‘em on your head, and the feeling of quality carries over. Save for a handful of notable flaws, this is perhaps the best headset that Turtle Beach has ever produced.

We’ll start with the form factor. The Elite 800 feels solid from the moment that you first pick it up. It’s not so heavy that it’s uncomfortable resting on your head, but nothing about it feels flimsy or poorly put together. The thick plastic is also adorned with flourishes of metal and blue plastic, and the thick earcup padding looks eminently comfortable even from a distance. There isn’t even a visible mic jutting out from the thing, though there are actually two — they’re invisible, built directly into the unit.

If you wanted to describe the headset in one word, that word would be “sleek.”

The stylish design sensibilities carry over to the charging base as well. The oval-shaped unit is topped by two small depressions, one of which is fitted with magnets and charging contacts. In charge mode, the headset sits upright, with each earcup slotting into its own shallow well.

The magnets do a good enough job of sliding the contacts into place, but it’s relatively easy to set the headset down in the charging bay incorrectly. Improper placement prevents the Elite 800 from charging, so it’s important to be careful when setting it into the cradle. One handy tip that Turtle Beach’s documentation doesn’t mention: If you hear the headset’s power cycle on, then off, after you set it down, you know it’s charging.

TurtleBeach Elite 800 review hinge macro

The base station connects to a PlayStation 4 (it also works with PlayStation 3, and with mobile devices using Bluetooth) via a USB cord, for power, and an optical audio cable, both of which are included. The optical audio is expected, but the fact that the base station/transmitter draws power from the console isn’t ideal.

The PS4 has only two USB ports located on the front of the machine, and one of them always has to be occupied if you’re using an Elite 800. Couple that with the fact that the PS4’s DualShock 4 controller already doesn’t have the best battery life, and you can see where problems might start to crop up.

That’s not the only problem with the base station, however. The PS4 doesn’t provide a charge to the transmitter when the console is completely powered down. Sony does offer a “Rest Mode” that continues to send a charge through connected cables, but it’s all too easy to shut the whole thing off and stop charging the headset. It’s possible to wire the Elite 800 directly into another power source, such as a computer, but this problem could just as easily have been solved by including a wall plug power adapter for the unit. As is, you’ll probably want to go grab one for yourself.

Power is also sometimes a problem with the headset itself. Turtle Beach promises 10 hours of life on a full charge, but that number comes down when features like Active Noise Cancelling are used. If you’re prone to participate in marathon gaming sessions, it might be a good idea to keep a backup pair of headphones handy. The headset also does a terrible job of communicating when low on battery power; instead of simply shutting down, the audio starts to crackle and fade in/out, giving the impression that there’s signal interference.

Despite these issues, the Elite 800 makes a strong case for itself in the realm of overall performance. It’s comfortable to wear thanks to the thick, padded earcups and additional padding up top. The material is surprisingly breathable, keeping ear sweats at bay, but discomfort sometimes crops up during especially lengthy sessions thanks to a snug fit that presses the inside of the headphones against the tips of your ears.

In terms of sound, the Elite 800 delivers dynamite performance. Positional audio, enabled by DTS Headphone:X 7.1 virtual surround technology, is among the best we’ve heard in a two-driver headset. It’s easy to pick up on an audio source by both location and distance, even when you’ve got heavily layered audio blasting through the headphones. For multiplayer games like Destiny or Call of Duty: Advanced Warfare, there’s a definite advantage in being able to tell where potential threats are coming from.

TurtleBeach Elite 800 review controls

The Elite 800 also has a multitude of settings to fiddle with. The earcups and snug fit go a long way toward providing passive noise cancellation, but there’s also an Active Noise Cancellation mode and a range of mic monitor settings for different environments. Active Noise Cancellation definitely isn’t for everyone, but it’s handy – as is the variable mic monitor – in all different types of playing spaces.

As usual, Turtle Beach’s own “Signature Sound” setting provides the best overall virtual surround experience. There are four categories of EQ settings, for Games, Movies, Music, and Stereo, and multiple tuning options in each, with more available to program into the headset using a Windows-connected Elite 800 and the Ear Force Audio Hub app.

It’s a lot like the company’s Xbox One-friendly flagship, the 500x, but with a very important difference. The Xbox cans communicate which setting is active using high/low beeps that practically require the user to have a cheat sheet on hand. The Elite 800 addresses this problem, using a pre-recorded voice that communicates settings changes as you make them.

While it’s very handy, cycling through the headset’s various settings can also be a pain. Everything from EQ settings to power to mic monitor to Bluetooth on/off (the Elite 800 can pair with mobile devices) is managed using four-way touchpads on both the right and left earcups. It’s convenient, but the controls are also extremely sensitive, to the point that an errant brush along the side of your head can too easily change things up.

Overall, the Elite 800 is one of the best headset solutions available for PlayStation 4. The build quality, the audio quality, and the added features – particularly Bluetooth pairing (take calls while you game!) and membership to Turtle Beach’s Elite program (mainly for the two-year warranty) – amount to a superb package overall. It’s not without its shortcomings, but in the inconsistent market of wireless headsets for next-gen consoles, the Elite 800 is a standout option. For a premium price, of course.

Highs

  • Fantastic, powerful sound
  • Stylish design
  • Lots of handy features
  • Extremely comfortable to wear

Lows

  • That quality comes at a premium price
  • Charging issues if you use power save with your PS4
  • Headset-mounted controls are less than ideal

Who invented the walkie talkie?

The original inventor of that walkie-talkie is actually the focus of some disputes. A similar 3 names come up again and again, but how many of those names deserves the foremost credit? I’ve to confess, I had a tough time deciding.

The first name to emerge is Canadian inventor Donald L. Hings. Reported by his blog,

“The “walkie-talkie” is Don Hings’ most well-known invention. The earliest versions of this device were designed as portable field radios for the bush pilots of Consolidated Mining and Smelting (now Cominco), who had to fly their planes between remote sites in the far north of Canada. The first true walkie-talkie was built by Hings in 1937, but it was not called a walkie-talkie at the time. In Hings’ notes, it was simply a two-way field radio. They were also called wireless sets, or “pack sets”. The term “walkie-talkie” (sometimes “talkie-walkie”) was coined by journalists reporting on these new inventions during the war”.

The site maintains (fittingly, I think) that walkie-talkies were not particularly recognized until the occurrence of the 2nd World War in 1939.

An additional name which is frequently mentioned is United states inventor Al Gross. Gross seemingly patented the term ‘walkie talkie’ in 1938, after which, the term was actually used by the media as a ‘catch all’ name for just about any/all lightweight 2 way radios. Undoubtedly, Gross worked on the technology and was instrumental in its plan, but did he devise the walkie-talkie? Lemelson-MIT appears to think so, as their blog says of Gross:

“The pioneer nonpareil of wireless telecommunications is Al Gross. In 1938, he invented the walkie-talkie. In 1948, he pioneered Citizens’ Band (CB) radio. In 1949, he invented the telephone pager. His other inventions include the basics of cordless and cellular telephony. (…) Determined to exploit the unexplored frequencies above 100 MHz, Gross set about inventing a mobile, lightweight, hand-held two-way radio. In two years, Gross had invented and patented the “walkie-talkie” (1938)”.

If Hings invented the walkie talkie back in 1937, then that signifies that Gross basically re-invented the identical device in 1938. If that is undeniably true, then certainly Hings is the chap most responsible, right?

Well, before you make your minds up, let Wiki Replies present some more names; their account of that walkie-talkie’s creation states that,

“The first radio receiver/transmitter to be nicknamed “Walkie-Talkie” was the backpacked Motorola SCR-300, created by an engineering team in 1940 at the Galvin Manufacturing Company (forerunner of Motorola). The team consisted of Dan Noble, who conceived of the design using FM technology, Henryk Magnuski who was the principal RF engineer, Bill Vogel, Lloyd Morris, and Marion Bond”. 

This Motorola team, headed up by Dan Noble, actually made the walkie-talkie in 1940, a full three years after Hings allegedly created it and 2 years after Gross apparently patented it. Ugh. This is giving me a headache!

So, perhaps we can clear this up a little now. The name ‘walkie-talkie’ was commonly applied to WW2-era Motorola radio, which led to Dan Noble’s staff being accredited with its creation. That is true, Noble and co DID create that particular model, however the technology itself had clearly existed before.

Now, Hings’ model was noticeably more portable, and pretty different to the Motorola model. Hings named his invention a ‘packset’ so it was consequently entirely probable for Gross to have patented the same invention (under the term ‘walkie-talkie’) in 1938 and for that name to migrate over to the Motorola adaptation, via the wartime press (1939 – 1945 was not a well-known era of journalistic accuracy, lest we forget).

Reported by Wikipedia, Hings’ model did not get used by the forces until 1942, the results of which would be Don Noble and co being credited with the invention, with Hings being relegated to the spot of just another engineer (Hings was employed by the allies during WW2) who was working on armed forces gear.

Largely, I’d say that Hings is likely the likeliest inventor of the initial technology and definitely of the portable system we understand today. Still, with so many talented inventors functioning at around the same time, this indicates as possible to claim Gross as inventor of the walkie-talkie as well. Hings pioneered it, Gross patented it and Noble’s team brought it into mass manufacture and normal usage. There. Simple, right?

How to Use a Walkie Talkie Headset

The basic functioning of walkie talkie headsets or two way radios is similar to standard radios. They receive RW or radio waves over the air. Once radios have received the radio waves, they convert it into sound. However, two way radios also convert sound to radio waves and transmit it back to another receiver. In simple words, these special types of radios can receive and transmit a radio signal simultaneously. Moreover, such radios use two different radio frequencies. This ensures that they can receive and send signals at the same time.

Most of the two way radios in modern times also allow scanning. Through scanning, a user can easily check if anyone is sending a transmission on a particular frequency. If the radio which is being used detects a private line tone, it will stop scanning and lock on that particular channel. This will allow the user to speak and transmit on the same frequency. As mentioned earlier, modern radios allow a person to use multiple channels. However, a walkie talkie headset should be able to generate and transmit radio waves in many different frequencies. All the frequencies should have minute fluctuations with each other.

Applications Uses of Walkie Talkie Headsets

These special type of radios have always been in demand even with all the mobile phones and laptops. Such radios facilitate easy accessibility and instant communication. Moreover, you can communicate with a bunch of people at the same time. With such a radio, you don’t have to call everyone individually and spend a lot of your hard-earned money.

These radios can be used for many different purposes. They are often used in public safety, recreation camps, military training and other businesses. Moreover, they can also be used as toys for children. Two way radios come in many different designs at affordable prices.

These type of radios can also be used in the medical industry. They can be quite useful in admitting patients or attending to people in emergency waiting areas. They also come in handy with outpatient clinics, pharmacies, and surgeries. Such radios can also be used in food industry. They can be used by waiters, kitchen staff and delivery staff in restaurants and so on.

Every person finds it easy to use these radios. Moreover, they are not as complex or difficult to use as mobile phones and other such communication devices. A walkie talkie headset is always the best option to communicate at work, play or home. Such radios can be used in many different situations. Even the most popular communication devices can not challenge the ease of use associated with such radios.

Here Are More AM Suggestion

This can be found over on this internet site, please enjoy

I thought you should know that the FCC has just licensed a digital TV station with an ancillary service in the form of an analog FM radio station. This new service can create thousands of powerful FM radio stations, which can be leased to current AM radio stations now struggling with broadcast difficulties.

Recent studies have shown that the 0.62 MHz now unused by DTV stations can be efficiently employed for other services, with no interference to or from either the DTV reception or, for example, FM radio reception. No new spectrum, or change in current spectrum use, is required. FM receivers, which can receive all VHF and UHF TV stations’ analog audio, were readily available since the 1980s from many manufacturers, and could easily be again.

The first DTV station licensed to broadcast this added analog FM is W26DC-D in New York. No interference of any kind has been observed. It uses the upper 200 kHz of the digital channel for monaural analog FM, and is well received by the older FM radios mentioned above. (Stereo FM analog, and digital radio, could also be broadcast.)

The FCC had previously shown concern that this added ancillary service might adversely affect new cochannels, but this has been disproved for the specific conditions employed.

This extended use of DTV spectrum could solve the problems of current AM radio stations by allowing them all to migrate to this new FM band, with no need to disturb any existing service. All that is needed is an FM transmitter output injected into the antenna line of a full- or low-power digital television station.

I hope advantage can be taken by the radio and television industry of this novel spectrum use.

ENFORCE THE RULES

As a major player in the world of AM radio and as one who is vested deeply, I am continually amazed at people who are not invested trying to tell us how to live.

AM radio in itself needs no improvement!! It works just fine. The problem is simple: The FCC has dropped the ball and fails to recognize the problem is the environment surrounding it. It is man-made interference that has caused the problem, and if the commission had enforced the incidental radiation rules, we would not be compromised as we are today.

All these hearings and meetings always attack the AM spectrum itself. It is just plain wrong! Enforce the rules and make sure radio manufacturers build good radios.

I listen to AM with my Icom Ham Radio with its digital noise blanker and love every moment of it.

Tom King’s article (“King Lays Out ‘Critical Steps’”) in the Sept. 24 Radio World was right on — except for C-Quam, which was a disaster.

Just because the inventor of the best stereo for AM was a eccentric old man and didn’t have a ton of money to spread around in the propaganda war The Commission selected C Quam. They said it was in the public interest… The Washington bureaucrats wouldn’t know public interest if it hit them in the backside. Face it — AM broadcasters, we have been screwed by the government. Maybe if some of these high-test consultants would get their heads out of their backsides we could salvage AM.

LATE TO THE PARTY

The problem with NextRadio and iHeartRadio (“Coleman Says Demand ‘Strong’ for NextRadio,” radioworld.com, Aug. 1) is that they are a few years too late to the party.

All of the college kids I know (and I work for a college radio station) use the free app from TuneIn Radio.     If you’re not on represented on TuneIn, you’re not really streaming anyway.

Students don’t like to have a separate app for every station they listen to. That just causes clutter on their device … and TuneIn even has some AM stations represented.

Do 2 Way Radios Work on Cruise Ships?

Yes, two way radios DO work on cruise ships. However, because the same channels tend to be a bit overused, passengers can expect a fair amount of chatter and signal interference when using their radios.

I suppose the two way radios/walkie talkies would be the best option. But, how important is being in constant communication with the rest of your family anyway? A ship, while large, isn’t huge. If you know the general area where people will be, you could walk over and find them. Preset arranged meeting times and places would work as well. People were able to get along fairly well without being able to directly communicate with each other at every moment of the day

So, aside from the option of setting pre-arranged meeting times, a 2 way radio isn’t a terrible idea, especially if you have kids. Many people reading this might simply ask why they can’t use their mobile phones. That is a very good question, after all…

If you’re going on a cruise this summer (or anytime, really), you need to be aware that your mobile phone is going to cause some problems.

Many cruise passengers are unaware and/or totally ill prepared for this fact and the cruise companies themselves are at least partly to blame for the lack of information in this area. So, will your mobile phone work at sea?

The answer is most often always “You can subscribe to our cruise line cell phone network.” What they won’t tell you is the rates you will be paying. You certainly won’t be able to find them online, and to get a proper answer, you’ll have to call the cruise line to get a full break down of what they charge for access to their cell networks. As a company that sets their own international calling rates for the Talk Abroad SIM Card, we can see the cruise ship networks in our list, and it does not look good. If you subscribe to their network, you’ll be paying anything from $4 ~ $8 per minute, depending on your location and who you are calling. Don’t forget also that they’ll be charging you for receiving inbound calls

As we’ll soon see, taking a mobile phone on a cruise can represent a logistical nightmare. At the same time, however, many of us feel naked without a phone?

More problems are presented in the form of scheduled stops (although these can also represent opportunities for a higher – and cheaper – level of connectivity).

If the ship is close to the coastline, and has multiple port of call stops, you’ll typically be able to get a terrestrial signal from the nearest land cell phone tower – up to a mile from the coast. It’s highly unlikely that you will be connected with 3G speed signals, as evidenced in my previous blog, you will need to have a low-wave 3G frequency like 800 or 900 Mhz – frequencies not typically associated with phones manufactured for North American consumers. So what can be done? You can rent an international cell phone that works in port, and a short way out to sea. If you really must stay connected on your boat, get in touch with your cruise travel agency and request information about the on-board cell phone rates and subscription fees

So, using mobile phones on a cruise is both difficult and supremely costly, but arranging a meeting time is also likely to cause more than a few headaches. two way radios have their problems, but may in fact be the best way to keep in contact, depending, of course, on how important a factor this is for you.

The size of modern cruise ships are such that they are usually measured against small cities, this means that communications are even more important than before. Experts in two way radio communication are 2wayradionline.co.uk
