Martian Homes Could Be Built In Just 24 Hours

Published by:

By the end of this century, it seems highly likely that people will be living on Mars. It sounds utterly mad, until you consider that there were only 66 years between the first powered and sustained Human flight and Neil Armstrong setting foot on the moon…

However, a major problem with this idea (aside from the fact that no Human being has ever actually set foot on the red planet) is the difficulty posed by building habitation in such a hostile and extremely remote environment.

At the moment, even landing an unmanned rover on Mars represents a major scientific achievement, which makes Elon Musk’s plans to build a city there seem especially far fetched and ambitious.

Besides, at current costs, taking one kilogram of material to the moon costs between £61,000 and £122,000. That’s a lot of money, even for bare essentials like building materials and water reserves.

Now, however, one man thinks he may have the answer…

Dr. Behrokh Khoshnevis of the University of Southern California’s Viterbi School of Engineering is working on a groundbreaking new method of building that, if applied to lunar or Martian colonisation, could bring us all that much closer to seeing cities on Mars or the moon in our lifetimes.

Essentially, Dr. Khoshnevis has come up with a way to ‘print’ buildings.

The construction technology, called Contour Crafting, fashions an entire building, layer by layer, according to a predetermined outline. Khoshnevis initially created the technology in order to provide cheap, quick and safe housing for emerging nations, or victims of natural disasters.

It is hoped that such building methods will also lower the demand for wood, thus having a beneficial effect on the rainforests and other areas that are being aggressively deforested for timber.

In addition, the concrete walls built by the Countour Crafter are three times stronger than a brick wall.

Writing for Nasa, Dr. Khoshnevis said, “Automated building technologies will revolutionize the way structures are built on Earth, in dense urban environments, in difficult-to-build and difficult-to-service sites, or in remote and hostile regions of the globe. The technologies under development by our group have the potential to simplify construction logistics, reduce the need for hard physical labor by assigning humans to a strictly supervisory role, eliminate issues relating to human safety and produce intricate, aesthetically refined designs and structures at significantly reduced construction cost”.

Theoretically, these buildings could be described via a computer model and built remotely, using the Martian landscape in lieu of bricks and mortar. The buildings could be ‘printed’ in around 24 hours and would be every bit as strong, (or stronger) than the building you are currently living in.

TURTLE BEACH ELITE 800 REVIEW

Published by:

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

Buy The Right Kenwood Radio Earpiece So You Can Work Hands-free

Published by:

Radio earpieces are extremely important when you have to perform tasks where you can’t use your hands to hold the radio to communicate with your people. Furthermore, earpieces are also important for employees who have to take important calls but their hands are not free to pick up those calls. Take the employees and workers working in a restaurant for examples. These employees cannot pick up calls on a handset since their hands are busy in preparing food for their customers. If you are a person who has to use a radio on his job, you need the earpieces that provide you comfort.

Kenwood radio earpiece is one of the best you can find on the market. They are easily available online with all the necessary accessories. You can see the pictures and decide the type of accessories you want with your earpiece. There are many different types of earpieces available from Kenwood but most of them come with a few accessories more or less. There isn’t much difference in the quality of the earpieces or how they are built. One important thing you must note is that they will only fit Kenwood radios so buy them only when you have Kenwood equipment.

The Kenwood radio earpiece comes with all the accessories that not only make your job easier but also provide your ears the comfort it needs. The pieces that go inside your ear are prepared in many different designs. In most cases, the earpiece will go inside the ear and fill your ear canal. Most of these earpieces come with the surveillance tube that lets you disconnect the audio tube in a second when you are doing a sensitive task. The coil tube extends due to the coiled structure it has but it only lets you hear whatever is being communicated over the radio.

The earpieces are available in different forms but a focus is kept on making them hypoallergenic and non-invasive. If you are a person who has to keep the earpieces on for hours, you will not be comfortable with most of the shapes of earpieces. After a couple of hours they all will be a bit painful for you. Kenwood, a reputable company in the multimedia industry, allows you to have a custom earpiece in this case. This custom earpiece fits your ear perfectly so you can have your Kenwood radio earpiece on even if you have to work for 3 hours or more.

Furthermore, you can also buy the PHS air blower that can be bought separately to clean the tube you are using with your earpiece. These earpieces are made with people with active and busy lives in mind. Therefore, you can wear these earpieces during the busiest days without worrying that your earpiece might fall. If you have a Kenwood radio and you need to communicate stealthily, search on the internet for the best earpiece from Kenwood for your job.

Legalize it? Colo. considers one-ear, in-car headsets

Published by:

Colorado could become more friendly for hands-free talking under a proposed tweak to state traffic law.

The bill would specifically legalize the use of one-ear headsets by drivers, if connected to a mobile phone.

Current Colorado law bans the use of “earphones” behind the wheel, which is defined as “any headset, radio, tape player, or other similar device which provides the listener with radio programs, music, or other recorded information through a device attached to the head and which covers all of or a portion of the ears.”

While that definition does not specifically cover phone calls, it leaves enough ambiguity in law that a small group of House Democrats wants to clear it up.

HB 1207 would add an exception to the definition of “earphones” in state law, to exempt: “a headset that only covers all or a 10 portion of one ear and that is connected to a wireless, hand-held telephone.”

The house transportation committee unanimously passed the bill on Thursday morning.

Colorado law does not specifically address the issue of hands-free phone use versus calls made with a handset held to the driver’s head. Under Colorado law, adults are allowed to engage in phone calls behind the wheel, while minors are not.

Numerous scientific studies conclude that hands-free talking is not significantly safer for drivers than talking with the phone held to the ear.

More important than tying up a hand is the fact that engaging in a phone conversation ties up the brain, splitting a driver’s attention between the call and the road and using a significant chunk of the brains cognitive capacity when it would be better applied to the task of driving.

In 2013, Colorado police officers reported that 1,311 crashes were caused at least in part by distraction due to a cell phone, roughly the same number caused by distractions from passengers actually in the cars that crashed.

That statistic does not differentiate between the use of a phone for talking versus texting. Texting behind the wheel is illegal for drivers of all ages in Colorado.

Where Are Sepura Radios Used?

Published by:

For people who are curious where Sepura radios are used, then this article is for you. Sepura is a highly respected company that designs, manufactures and sells radio technology. However, the company is known for providing accessories, like a Sepura radio earpiece to radio networks. The company has gained a reputation to supply radios that are highly secure, feature-rich and durable. In fact, with these so many features, the only real question is – in which situations do Sepura radio are not suitable? The answer is – hardly. Nevertheless, this article is going to enumerate a few popular uses for Sepura radios.

Public Safety

One of the most common uses for Sepura radios is in the field of public safety. There are plenty of reasons for this, but the most compelling one is because of the Sepura’s mobile gateway technology. Because of such technology, officers in public safety will be able to communicate with each other no matter the location, even for “dead spots. Sepura radio also comes with a one-of-a-kind noise suppression technology. It’s so good at it that even with wailing sirens, you can still hear crystal clear audio. However, if you really want to block-out all the background noises, then Sepura radio earpiece can help you with that.

Seupra also provides radio technologies that are all designed to streamline and increase the functionality of the communications like allowing real-time information sharing with emergency services, the control room and colleagues; also, Sepura provides apps that make using the technology easier. The ability of Sepura radios to withstand a heavy beating makes them very ideal for tough and disaster scenarios. Lastly Sepura radios come with a Man-Down feature, which provides critical help for any officers that might need backup or assistance.

Oil And Gas

Another popular use for Sepura radios is in oil and gas industries, especially offshore installations. These kinds of work environments are considered as “high risk”, thus worker safety of utmost importance. Therefore, accurate and clear communication is crucial for the safety of all the workers. Sepura radios offer the one of the best radio communications and technologies to provide that another safety layer.

The notable safety features are the Lone Worker and Man-Down. These features are especially designed to ensure safety of the workers and provide immediate help if the situation arises. The radios and accessories are designed in a way so that it can be easily operated even if the user is wearing thick gloves. Sepura radios also feature real-time information authorization access to different areas. This helps protect assets and ensure information security. Also, Sepura radios come with an app specially designed for oil and gas environments as it helps in reducing incidents, liability exposure, promoting safety and full audit-trail.

Sepura is a company that designs, manufactures and sells radio and radio based-technologies from handheld devices, networks to accessories, like the Sepura radio earpiece. Because of the many features, their radios are extensively used in different locations, industries and agencies. The company has put a lot of effort to put features that ensure safety and clear communications, thus it has earned a place in public safety and oil and gas industries.

New Sighting Suggests That Extinct Tasmanian Tigers May Yet Live

Published by:

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.

What Is a Covert Earpiece?

Published by:

This site is an old one, but still very important. Without saying i told you so…. but it was always inevitable!

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

covert earpiece

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

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

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

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

Benefits of Two Way Radios to the Hotel Industry

Published by:

Over the years, hotel communication has had to change and develop, becoming more and more efficient than it was. This is courtesy of the advancement in technology over these years. Passed are the days that two way radios were exclusively for police official use. Nowadays, these pieces of technology that have been improved and made even better are used for hotel communications. These state of the art technology have lots of benefits that any of us have been recipients of in one way or the other. Being in the hospitality industry, I can outline with ease some of the major benefits that these 2 way radios have brought into hospitality.

First and foremost, the service offered to the customers in the hotels has been improved. When taking orders in the restaurants back in the day, the waiters had to go all the way back to the kitchen to request for the order. Okay, this was not much of a problem for the small establishments. However, as the hotel grew and the number of employees grew, the kitchen area would get so crowded that out was difficult to get the job done. With the new 2-way radio technology however, all the waitress have to do is call out the order through the gadget and it is received on the other end saving on the time.

Also, being in the hotel business, I can testify that just like in any other business, there are major up and downs. However, unlike many other businesses, there is no space for screwing up. A single mishaps can cost you millions. The best way to avoid this from happening, is by communicating with the manager and airing out issues that might be there. Communication is key in this business and the sooner an issue is sorted out the faster you can move on and provide quality service to your customers.

Security. Do we really have to spell out the benefits that 2 way radios have with regards to security in the hospitality industry. The hotel industry harbors people of different kinds and who have different intentions. As such, the necessary measures need to be taken to ensure the security of the staff as well as the other peaceable customers. The rate at which the security personnel react to distress calls can be the determining factor to how the security emergency turns out. The 2 way radios have greatly increased the speed in which the security personnel respond to security threats and also ensure that they are on top of every situation as every member in the hotel informs them when there is a security risk.

In addition to the above benefits, the Two way radios are cost effective and are also very easy to use. With the 2 way radios, the management does not have to pay any network provider so that they can communicate. This reduces the cost of operation of the hotel by a great margin. To talk through to the other person on the other end of the line, all you have to do is press a button on the front and you will get through. It is as easy as that.

The benefits of the Two-way radios are numerous. This makes them a major asset to any hotel.

We Have A Look Under The Bonnet Of The IC-F4029SDR

Published by:

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

Professional Digital Licence Free Transceiver

The IC-F4029SDR professional digital licence-free transceiver utilises the latest 6.25kHz ultra narrow digital voice technologies, providing digital clarity, razor sharp signalling performance and a level of secrecy from less congested dedicated digital PMR channels.

The IC-F4029SDR was recently featured on Channel 5’s “The Gadget Show” winning a comparison test against another leading manufacturer.

DIGITAL PMR 446 FEATURES

The IC-4029SDR utilizes 4FSK/FDMA modulation and 6.25kHz digital narrow channel spacing, which is half the channel spacing of the existing analogue PMR 446 system. This way, the 100kHz band width allocated for digital PMR 446 is efficiently divided into 16 channels, or twice the current analogue voice channel capacity making this product incredibly spectrum efficient.

A Path from analogue PMR 446 to digital PMR 446 in one unit

By changing the channel setting, the IC-F4029SDR can be used on existing analogue PMR 446 channels. This provides users with an upgrade path from analogue PMR 446 to digital PMR 446 in one unit. Being analogue/digital compatible, any businesses or private users currently using analogue PMR446 can begin replacing their analogue radios with IC-F4029SDR and enjoy digital quality as well as relief from congested spectrum.

32-status messages

32 codes of prefixed status messages can be sent and received. 16-character messages and 6 types of alert beeps sound that for call reception, are programmable for each message.

“Common ID” group code

This function is similar to an analogue CTCSS/DTCS code. By setting 1–254 common ID codes, the IC-F4029SDR opens its squelch only when a matched code is received. It provides quiet stand-by and group call functions while sharing a channel with several groups. The code “255” is the fixed code for an all stations call.

Security of digital voice

‘Eavesdropping’ by current scanner receivers is impossible at this stage. Since there are no other competing radios, initial users will have a high level of security in digital voice communication mode.

Additional Digital Features

Group call functions (up to 254 digital codes available)

Programmable 32 status message of up to 16 characters each can be sent to individual or group member radios when in digital mode. This is configurable by a PC

In addition to Icom default channel settings, other channel zones are preprogrammed to have matched settings with Kenwood and Motorola PMR446 models currently on the market. These radios can be sold to match Motorola/Kenwood current analogue configuration reducing the necessity to reprogram radios for customer’s fleets consisting of non- Icom radios.

ANALOGUE PMR 446 FEATURES

“Smart-Ring” and “Ringer” function

The “Smart-Ring” function checks the availability of your group members within the operating range. The “Ringer” function is used for manually sending a ring tone instead of a voice call. 16 types of ringing tones are available.

Tone find function

The tone find function allows you to find a tone used in a channel to decode a tone.

Built-in CTCSS/DTCS

50 CTCSS tones and 84 DTCS tones provide quiet stand-by. DTCS inverse mode is also programmable.

Lithium-Ion battery pack and rapid charger as standard
