Yes, 2 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 two 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

In the beginning, there was analog technology, which uses frequency modulation (FM) to produce a continuous wave with the voice signal. An analog two-way radio works as both transmitter and receiver, with that continuous wave in between. Analog has been the primary technology platform since the initial development of wireless communications.

Analog radios have been used for business applications as far back as 1933.

  • Analog Advantages: The integration of such a simple system into a single computer

chip has dramatically reduced the cost of analog radios.

  • Analog Disadvantages: The analog radio system has many functional limitations, and

the technology has been around so long that the scope of possible innovations is virtually exhausted.

ALONG COMES DIGITAL

Digital two-way radios operate by encoding, transmitting, and decoding sound waves. The signal is represented by binary numbers—1s and 0s—that correspond with voltage values. Inside the radio, the vocoder—an analysis/synthesis system used to reproduce human speech—encodes the transmission. The radio sends the signal, and the vocoder on the receiving end decodes it.

In addition, the software in digital radios contains an algorithm that recognizes the difference between voice and background noise and cancels undesirable audio for clearer, cleaner sound quality. Digital two-way radios can also include software applications that integrate into existing computer networks and phone systems. As a result, digital radios can enable a multitude of additional functions, including GPS, text messaging, and other information sharing, communications, and operations programs and capabilities.

By proactively transitioning to digital radios now, your organization will enjoy greater benefits immediately, and your fleet is ready for the high-efficiency, app-driven innovations coming in the future.

FIVE REASONS TO GO DIGITAL

  • Improved Audio Quality • Enhanced Clarity throughout the Coverage Range
  • Greater Efficiency • Extended Battery Life • Applications that Add Functionality
  1. Improved Audio Quality: Digital technology reduces external background noises during

transmission, thereby making the digital technology platform ideal for situations such as

noisy manufacturing and processing plants, or outside in windy conditions.

  1. Enhanced Clarity throughout the Coverage

Range: While an analog radio is capable of producing a clear signal within its peak performance range, once the signal moves too far from the transmit point, the analog audio will slowly fade out until it is unrecognizable. By contrast, a digital signal stays much stronger and clearer to the limits of the coverage range.

  1. Greater Efficiency: Digital radios operate in

Dual-Capacity Direct Mode (DCDM), which means that radios can share the same channel by alternating time slots. These time slots move incredibly fast, and since they alternate, more simultaneous talking paths are possible on each channel with no degradation. Plus, key information such as unit ID, status buttons, and enhanced text messages can be embedded into a single digital radio channel. In many cases, migrating from analog to digital allows users to increase talk paths without a repeater.

  1. Extended Battery Life: Since digital radio transmitters are not constantly “on,” digital

radios generally have a significantly longer battery life than analog models. When events run all day, that can mean the difference between efficient communications for the full cycle or the headache of a number of dead batteries that need swapping out and recharging.

  1. Applications that Add Functionality: Software applications are available to optimize digital

platforms using integrated Internet Protocol (IP) networks. For example, some of the leading app providers for Motorola MOTOTRBO digital radios include:

TABLETmedia

NeoTerra Systems

Twisted Pair

TurboVUi

Teldio

MOVING TO DIGITAL

For those switching from analog to digital, there is good news: Digital platforms provide a migration path that allows for simultaneous use of digital and analog radios. Backward compatibility allows organizations to gradually replace analog devices with newer digital models without the added stress of shifting to a new system. Also, many analog radio accessories are compatible with digital devices.

THE MOTOROLA CP200 AND CP200d

The existing CP200 is one of the most popular two-way radios ever produced! So the question is: How can you improve on the Motorola CP200? The answer: By creating a version that leverages all the benefits digital delivers.

Introducing… the CP200d digital two-way radio, a new model that retains the same simplicity and durability that have made Motorola’s CP200 the industry standard for years. The new CP200d uses a nearly identical form factor with similar operation. Plus, this highly flexible digital model is backward compatible, so it uses the same chargers, batteries, and speaker-microphones.

Motorola is adding sensible options to your two-way radio fleet by offering the existing CP200 device in the CP200d digital-capable version that can be fully converted from analog to digital operation at a later date. That means you can use a phased migration approach by using your new CP200d as an analog device now, and then with a simple programming change, switch to digital at any time in the future. Or, you have the option to take out-of-the-box delivery of the CP200d as a digital device from the get-go.

THE TALE OF THE TRBO

MOTOTRBO is Motorola’s next-generation system of digital portable and mobile radios, repeaters, and accessories. Thanks to the advantages of digital technology, this professional line delivers advanced performance to increase capacity and productivity while integrating voice and data communications.

Versatile and powerful, MOTOTRBO combines the best of two-way radio functionality with the latest digital features that deliver ease of use and added performance to meet your communication needs from the field to the factory floor. With exceptional voice quality and long battery life, MOTOTRBO keeps your work teams connected when communication is a must.

When it comes to discreet affairs, there definitely must be a discreet communication. Whether it is a security personnel or just a private group of designated people. Radios are used for communication between compatible devices within a specified location. Nevertheless, it would be less comfortable if someone talks via the radio and everyone hear the entire communication. Given the different types of two-way radios in the market, they usually come with a compatible earpiece. Among the most common radios are the Motorola radios. It would be super discreet and stylish if you had AMotorola radio earpiece to accompany your device. Some of the ideal Motorola 2-way radio earpiece connectors at EarpieceOnline include the following;

CP040 & DP1400 2-Pin Connector

This Motorola 2-pin connector can work with a number of Motorola 2-way radios. It can also support some of the old version radios such as the DP1400, GP040 and the GP300. Some of the novel version of radios that are compatible to this earpiece include the DP1400 and the DP1000.

Features of the connector

* It has a changeable Foam sock so that you can replace if it has worn out.

* The earpiece also has a comfortable and flexible C-shaped earpiece.

* There is a secure moulded ear hook, for holding firm on the ear.

* It provides high quality audio.

* It comes with a noise reducing microphone for enhanced reception of incoming voice messages.

* The earpiece has a plastic that is covered by a label clip PTT button. The wire PTT is separated from the microphone and an ear hangar earpiece.

* It has a RoHS compliant feature and comes with Motorola earpiece 2-pin connector GP300/CP040/XTN/DP1400 and GP340 adapters.

DP3400 & DP3600 Multi Connector

This is a multi pin connector works with all DP3000 & DP4000 range of radios, with a 12-pin connector, it slots perfect onto the side of the DP radio and is securely screwed in so that the earpiece is securely locked in.

Features

* It is incorporated with Kevlar Reinforced for better surveillance and security.

* It has a secure fit tube connector, to avoid accidents of it cut from rough encounters.

* It offers a high quality audio.

* The earpiece has a Lapel clip PTT button and a separate wire PTT. That is separated from a noise reduction microphone and an acoustic tube. The acoustic tube runs over the ear, the FBI style.

* There is a changeable connector for flexible modification and flexible mushroom plugs that you can replace whenever.

DP2400 & DP2600 multi connector

This is yet another different multi-pin connector that lets you connect to the DP2000 range of radios. This 8-pin connector fits on to the side of the radio and is locked in with a ‘pull out and slot-in’ connector, reducing the risk of broken screws or damage to the radio.

Features

* The acoustic tube runs over the ear and it has a secure fit connector for super surveillance and comfort.

* It has a separate wire PPT different from the acoustic tube and a microphone that reduces noise from the surrounding.

* The mushroom plugs are changeable and you can simply remove them when they are loose or worn out.

* It produces a high quality audio that reduces strain even when in a noisy environment.

GP340 & GP680

This multi connector is compatible the GP range of radios, including the GP340 and GP680. The Connector is a 13-pin connector and is secured on the side of the radio, with a screw-in to secure the earpiece to the radio.

Features

* This multi connector has a high quality audio reception. That makes it comfortable to use anywhere, even in a crowded, noisy place.

* There is a microphone, which is separate from a wire PTT and an acoustic tube. The microphone is a noise reducing microphone, that helps to make the other end-user be comfortable.

* It has a RoHS compliant and an over the ear acoustic tube that holds firm to the ear.

* There is an adjustable connector that is versatile to other devices.

An elegant and well fitted earpiece will not only promote surveillance, but it will also be comfortable on the ear. That will ensure it is safe from damages in rough situations. A Motorola radio earpiece will be beneficial if you want a comfortable communication without having to speak loudly over the radio. Some of the radios are also slightly heavy, which makes them more comfortable when using an earpiece, that is worn beneath the clothing.

Theoretically, you can use an unlimited amount of walkie-talkies on the same channel (although in practice you might experience a few problems if you took that suggestion literally). Basically, there isn’t really a set limit. You could use as many as you like provided they are set up correctly. Anybody set to the right channel and in range at the time of transmission would then be able to pick up the signal and respond to it.

Most radios have access to 8 channels. These channels each have 38 separate ‘identification tones’. The user sets his/her channel up with the desired tone and then only other users who know the channel/tone will be able to hear the transmissions. As a result, there are, in any given area, about 304 different combinations, so signal interference is unlikely to affect you.

Please do not interpret this answer as saying that your radio has access to 304 possible channels. It does not. It will likely only have access to 8. Some less reputable manufacturers tend to falsely imply access to 304 channels; this is simply not the case. You will have access to 304 possible tone/channel combinations, that’s all.

To better explain the CTCSS codes and how they work; we’ll include a little information from Amherst.co.uk’s FAQ page.

“CTCSS stands for “Continuous Tone Coded Squelch System”. These codes are also often called “Privacy codes” If a CTCSS tone is selected; a CTCSS sub-audible tone is transmitted along with the regular voice audio by the transmitting radio. The receiving radio, set to the same CTCSS tone, will only receive audio if it contains that sub-tone. Interference from other users on the same frequency is therefore rejected (unless they are also on the same sub-tone). This is a way of allowing groups of users of walkie-talkies on the same channel to avoid hearing messages from other nearby users”.

So, in conclusion, you can probably use as many walkie-talkies as you like on the same channel. As long as the units in question are of the same type (either VHF or UHF) and have the same CTCSS setup, then you simply shouldn’t have a problem. You also shouldn’t suffer from signal interference due to other users (although you may still experience signal loss/interference/degradation from other sources). We have talked about combating signal loss elsewhere, so please see the other questions if you have any problems in this area.

In a word?  Everything. Visual communication is the conveyance of ideas or meanings via visual images. This includes everything from illustration to logo design, from typography to road signs.

Employing visual communications in your business is a great way to increase your brand awareness. Today, corporate entities and their associated products can be readily identified worldwide, simply by an act of visual communication.

Consider the ‘McDonald’s Golden Arches’ Logo. When it is placed on a road sign, this logo is usually only accompanied by the number of miles away the nearest restaurant is. This suggests that the logo itself is so well known that no text is needed to explain it.

The Nike ‘Swoosh’ is another prominent example, as is Apple’s, um, Apple.

The subject of the corporate world’s reliance on visual communication (together with its effect on the rest of us) was covered extensively by Naomi Klein, one of our favourite authors, in her 2000 bestseller, ‘No Logo’. She says,

“Advertising and sponsorship have always been about using imagery to equate products with positive cultural or lifestyle experiences. What makes nineties-style branding different is that it increasingly seeks to take these associations out of the representational realm and make them a livid reality. So the goal is not merely to have child actors drinking Coke in a TV commercial, but for students to brainstorm concepts for Coke’s next ad campaign in English class.”

If you’re looking for a definitive answer to your question, look no futher than ‘No Logo’.

Visual communication can be used to convey instant meaning, which is especially good for road signs. Typically, road signs contain no words, just an image representing the thing that motorists are supposed to be aware of. A figure of a man digging up the road, for example, denotes roadworks ahead (although, to be fair, it also looks as if he could be putting up an umbrella). A silhouette of a deer (or, in Australia, a kangaroo) indicates the presence of animals in the area that may pose a danger to motorists (or themselves).

It is also used as a sort of communicational shorthand, with increasing levels of cross-cultural complexity. For example, horror movies would once have been advertised with a typeface made from blood, or slime, to convey the ‘horror’ of the movie. However in today’s world, such advertising would only be used in pastiche horror movies, or else horror movies that were being made to invoke a bygone era. Movies that used a stereotypically ‘ethnic’ typeface (such as to evoke a now-problematic ‘Chinese’ or ‘Indian’ feel), might now find that those typefaces are used for movies knowingly aimed at Asian American or British-Indian audiences.

Visual communication can provide a wealth of information in just one simple image, or a few words. The ‘Star Wars’ typeface, for example, evokes the science fiction film franchise, even if all it says is “Danger: High Voltage” or similar.

Thanks for reading my blog, here’s a piece of writing i actually loved reading. With their authorization i can repost it. I write lots of my own content pieces, but sporadically post other articles i think are remarkable, thanks for reading.

The City of Edmond faces a decision about whether to replace or upgrade public safety radio infrastructure to the tune of about $6 million, said Matt Stillwell, director of Public Safety Communications and Emergency Management.

Edmond purchased a 7-channel Motorola MHz SmartNet radio system in 1998. Seven years ago, the system interfaced with a different Motorola system operated by the state, Stillwell said.

“Our technology is going to be 20 years old in four short years,” Stillwell said. “… Think of your cell systems and how they have changed since the 1990s. The same dynamics affect radio systems.”

Changes in technology, governance and an aging infrastructure will inform what system changes the city should choose within seven years, Stillwell said.

The city maintains ownership of its seven channels and the state added 10 more channels to local sites, Stillwell said. All local governments use this system, but not everybody has paid for its maintenance. Only six municipalities help pay for the system.

“The citizens of Edmond are paying for a system of any (yearly) infrastructure maintenance, while other users of the same sites are not,” Stillwell said.

The City of Edmond joined the state’s system in 2007. A lot of other communities join the system through grant dollars, he said. The upgrade was paid for by state dollars and cost the city nothing, he said.

Questions are unanswered as to how many radios for police, fire and emergency management would be impacted by a new system, Stillwell told The Edmond Sun.

“We won’t have to replace all of the hand-held radios that are out in the field,” Stillwell said. “Most of the radios we have been purchasing for the last five years are digital capable and P-25 capable.”

The P-25 is a radio standard that all of the public safety radio vendors use, Stillwell added.

Directors of city departments recently identified $143.6 million worth of unfunded city projects they say the city needs. The Edmond City Council heard presentations about these needs, such as the public safety radio infrastructure, at a public workshop. (For coverage of other capital improvement projects discussed by the city, look at www.edmondsun.com.)

A funding source to pay for these infrastructure improvements is in the first phases of discussion, said Larry Stevens, city manager. There are concerns that the 2000 Capital Improvement 3/4-cent sales tax will not provide adequate funding for major capital projects, Stevens said.

The city welcomes public input by Edmond residents and future recommendations by the Capital Projects and Financing Task Force, Stevens added.

Either Edmond will partner with the state to upgrade with the latest digital technology, or pursue an independent digital upgrade without the cushion of state funding, Stillwell explained.

“The bottom line is we have to move away from that analogue. End-of-life issues are coming up with our technology,” Stillwell said. – See more at: http://www.edmondsun.com/local/x1760083917/City-faces-decision-on-radio-infrastructure#sthash.bqDBsfhK.dpuf

Radio earpieces look really cool. They are generally used for surveillance but some enthusiasts also wear them just for fun. Secret agents and spies in the movies have made these accessories really cool to wear.

Putting on a radio earpiece is not a tough job. To put on an earpiece, first of all you need to take that earpiece and microphone clip in your hand. The microphone is to be put where you are most comfortable with it. It can be put on your hands, specifically on your wrist. You must have seen Spies or Secret Service agents in movies lifting their wrists talk. This is where they are speaking into the mouthpiece on their wrists.

If you’re not comfortable with the mouthpiece on the wrist, you can also put it on the tie or on the shirt, on your chest. Once you have clipped on the mouthpiece, it is time to put on the radio. Take the wire dangling from the mouthpiece and put it inside your shirt. Take this wire out from the top of the shirt. This way the dangling wires will be completely hidden. Take the earpiece and put it on your ears. Make sure, that it fits tightly and would not fall off when you start to walk. You can put it on either ear. If you are wearing the mouthpiece on the wrist, you will find it comfortable to put the earpiece on the same side ear.

Once you are comfortable with the mouthpiece and the earpiece, it is the turn of the end which goes into the radio. Take this dangling wire connecting that end with earpiece and mouthpiece and put it inside your shirt. Take out the wire from the bottom of the shirt. Put it in the radio and clip the radio in its place on your pants. Once you have that these wires inside your shirt completely, you need to tuck in your shirt inside your pants so that none of the wires are visible.

Once everything is fixed, switch on the said radio and test the settings. If everything is working as it should be then you have put on the radio earpiece correctly.

Wait, you are not done yet!

Once you have tucked in your shirt inside your pants and put on your jacket, you need to test the comfort level of this piece by walking around a few paces up and down. If you’re comfortable with the earpiece and the mouthpiece and are able to talk on radio, then you are set for the job. If any of the wires are the earpiece or the mouthpiece is making you uncomfortable, you need to reset your wires.

The real advantage of a concealed earpiece is that others wouldn’t notice when you are talking on a concealed earpiece. If you’re uncomfortable wearing these or with the wires,you lose the advantage of a hidden radio earpiece. Therefore it is very important to check the complete settings by walking around.

Congratulations, you have successfully put on a radio earpiece. Now, enjoy talking like a secret service agent.

Boy. The newest walkie talkie is out of this world. I mean it’s just so beautiful and so advanced. I pity people who grew up without the 2 way radio.

Radio frequency identification (RFID) tags—devices that can transmit data over short distances to identify objects, animals or people—have become increasingly popular for tracking everything from automobiles being manufactured on an assembly line to zoo animals in transit to their new homes. Now, thanks to a new NIST report, the next beneficiaries of RFID technology may soon be law enforcement agencies responsible for the management of forensic evidence.

A typical RFID system consists of a microchip programmed with identifying data—the “tag”—and a two-way radio transmitter-receiver, called an interrogator or a reader depending on its use. The tag can be attached or embedded in the item to be tracked, with the radio either sending a signal to the tag or reading its response.

Common examples of RFID systems include the FasTrak and E-ZPass in-car tags for automatically collecting tolls, tagged prescription drugs that help pharmacies meet federal and state safety regulations, and credit cards with embedded RFID chips that provide a more secure way of transmitting card numbers than magnetic strips. RFID systems can read hundreds of tags in a few seconds and track an item as it moves through a process. More advanced RFID tags can sense and report on environmental conditions, or encrypt the data they send.

While some have used barcodes to improve their tracking, storage and retrieval processes, very few have implemented RFID because of concerns about startup costs, the reliability of the technology and the current lack of relevant RFID standards for property and evidence handling. To help agencies better understand these issues and properly assess the pros and cons of RFID evidence management, NIST recently published RFID Technology in Forensic Evidence Management, An Assessment of Barriers, Benefits, and Costs. The report is the result of a NIST-funded study on automated identification technology (AIT). The Technical Working Group on Biological Evidence Preservation, cosponsored by NIST and the National Institute of Justice (NIJ), commissioned the study and report.

The NIST report includes a helpful overview of AITs—focusing primarily on RFID and barcode technologies—and how they work. It describes, in depth, the types of RFID systems available (passive, active and battery-assisted), their price ranges, and the components necessary for a complete system. The report also details the barriers that agencies may encounter, followed by a series of successful RFID management case studies, including examples from the pharmaceutical and retail industries, and one law enforcement agency that has made the switch, the Netherlands Forensics Institute.

The practical question that agencies must consider—and one that the NIST report can help them answer—is whether RFID technology can produce measurable benefits and a positive return on the funds invested in a new system. The NIST report estimates that RFID systems can pay back their initial set-up cost in about two years.

Various factors can affect the payback period. For example, systems that track and manage larger inventories of evidence (100,000 or more items) will recoup costs more quickly than those handling smaller inventories. However, if multiple jurisdictions share the costs of a system, the payback period can be shorter.

With so much information around the web about earpiece’s it is hard to find the best and generally candid information. here is a piece from a good blog that i believe as factual, do not quote me on it but please read and enjoy

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.

BearCom, a nationwide provider of wireless communications equipment and solutions, today outlined the advantages that organizations achieve when they migrate from analog to digital communications.

Two-way radio users around the country are looking to harness the power of digital technology as they improve their communications capabilities, said Jerry Denham, BearCom President & CEO. When comparing analog and digital radios, each has their strengths, however there are clear benefits to migrate your radio fleet to digital.

On its website, BearCom offers a free downloadable guide, Five Reasons to Migrate to Digital Two-Way Radios. The benefits of going digital include:

  1. Improved audio quality

    2.    Enhanced clarity throughout the coverage range

    3.    Greater efficiency

    4.    Extended battery life

    5.    Applications that add functionality

The two-way radio market is clearly moving towards the digital platform, said Hugh Johnston, Product & Purchasing Manager at BearCom For example, the MOTOTRBO line from Motorola provides a range of digital radios that mirror the simplicity of analog. These radios can make the digital migration nearly seamless.

For typical commercial operations, BearCom suggests digital upgrade radios from Motorola Solutions, such as the CP200d, CM200d and CM300d. These models feature a similar look and feel to older analog counterparts with the added boost of digital technology.

The CP200d offers the ability to operate in both analog and digital modes, which makes it especially attractive to organizations in the process of transitioning to digital technology, Denham said. We think that audio clarity, flexibility, high-value and ease-of-use will make the CP200d a tremendous success.

Like the CP200d portable radio, the Motorola CM200d and CM300d mobile radios also offer the option to operate in digital or analog modes, so they fit seamlessly into an existing system, allowing users to migrate to digital at their own pace. Both the CM200d and CM300d radios are durable, easy-to-use and program and offer clear audio performance.

For added functionality, the feature-rich MOTOTRBO line of digital radios provides everything any professional user needs. Two of the most popular MOTOTRBO radios are the XPR3500 and the XPR7550.

Through December 31, 2014, Motorola is offering a rebate savings of $150 with the purchase of six or more CP200d, CM200d, CM300d or XPR3500 models. Also ask about generous trade-in credits towards the XPR7550.

So to carry on my run of content pieces from %link% on this website, I’ve decided to share one of my favorite content pieces this week. I used to be hesitant to add it to the blog as I really didn’t want to offend the original writer, but I hope he/she is happy that I loved reading their article and planned to share it with my readers.

Those tiny earbuds you bring along with you here, there, and everywhere are causing you to go deaf. At least that’s what audio specialist, and in-ear monitor pioneer Stephen D Ambrose would have you believe. To save you from the dangers of the common earbud, Ambrose and his team at 1964|Adel have created an entire new wave of %link% designed with patented technology to be safer for your eardrums, all of which are making the rounds in a new Kickstarter campaign.

The link between hearing loss and headphone use being drawn here is not a new one. For its part, 1964|Adel singles out a study from an L.A. Times report which cites an increase in hearing loss for U.S. teens in the last 15 years from 30 to 77 percent. The study in question ruled out ear infections and external environmental factors as causes, pointing instead to the higher prevalence of portable audio players, though it stopped short of specifically laying blame. That said, there are plenty of other studies blaming the blasting of headphones as a major contributor to hearing loss.

But Ambrose argues that hearing loss from in-ear headphones and %link%, specifically, is different due to the way they isolate the eardrum inside the ear canal. In the video below, Ambrose claims it’s not acoustic pressure (i.e. loud noises) that causes hearing loss, but the pounding of air pressure from the moving driver being sealed inside your ear canal, causing “pneumatic pressure” from the movement of the driver itself.

In response, Ambrose and 1964|Adel have proposed a new way to solve the very hearing loss epidemic Ambrose claims to have helped create with his original in-ear monitor design; four ways to be exact, stemming from four different headphone series. The new headphones employ 1964|Adel’s patented RealLoud Technology, which incorporates a “second eardrum” inside the earpiece designed to take the brunt of the air pressure to protect your real eardrum. The company even claims the design makes audio “sound louder,” requiring a lower overall volume level.

Adel in-ear module diagram

The first, and most affordable solution in the arsenal is the new Adel Control, a modular earphone that allows users to adjust features like bass and external noise to taste, tailoring the sound signature. At time of publication, the Control was still available as an Early Bird special for $100, half off the suggested retail price.

Next in line is the Adel Ambient series, which offers 4 multi-driver models, from the entry-level dual-driver Ambient 2, to the Ambient 12 which (you guessed it) is jam-packed with a whopping 12 drivers per side, labeled the “jewel” of the Ambient line. Pricing for the Ambient series starts at $200 for the dual driver set, and goes up to an impressively (relatively) affordable $500 for the 12-driver version, again, priced at half the cost of suggested retail for each. For reference, the quad-driver Westone W40 will run you the same price as the Ambient 12.

Next up are the 1964|Adel U-series, which take the shape of more traditional in-ear monitors, covering the entire ear canal. The U-series starts with a quad-driver pair for $300 — down from a suggested $500 retail price — and the series goes all the way up to the 8-driver U-series 8, which will run you $720. The latter offers 4 drivers for the bass register alone, with two each for the midrange and treble, to create a massive sound.

Finally, the 1964|Adel A-Series includes both 10-driver, and 12-driver models, priced at $1,000 and $1,200 respectively — 40 percent off the claimed MSRP. Like most top-tier in-ear monitors, the A-series are custom tailored to the user’s ears for the ultimate fit and sound, while harboring a RealLoud secondary eardrum for safety.

Not only is 1964|Adel’s new project already funded, but it has already reached its stretch goal of $350,000, which provides an optional inline 3-button mic piece for all of its headphones. All of the new models are slated for release in May of 2015, with the exception of the A-series, which will be available earlier in February.

While we certainly can’t attest to the claim that RealLoud Technology actually makes these headphones safer, they are priced very competitively under the Kickstarter deal. And hey, if they offer competitive sound in their respective genres, what’s the harm in playing it safe, right? If you’re interested in finding out more, or ordering up one of 1964|Adel’s latest designs, you can do so today at its Kickstarter page.

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

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

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

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

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

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

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

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

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

For most people, clarity of sound when using their radios is very important. Only through clear sound will you be able to receive and understand the message being conveyed. For proper sound, you might consider using a good set of earpiece. Motorola radio earpiece is the ear piece to go for. This earpiece has been made using the latest technology to ensure you enjoy top quality sound.

Communications engineering is a disparate array of technological disciplines brought together under one all-encompassing banner. The disciplines considered to be part of a communication engineer’s skill set include telecommunications, mobile phone networks and Internet maintenance (but are by no means limited to those examples).

As we wrote earlier this month, any technology that aids in communication, from a walkie-talkie to a Skype account, is technically a communication technology; therefore, it also follows that anybody who works in these different areas can call him/herself a communications engineer.

The theory behind this move is that communications technology is becoming more streamlined and, to some extent, more homogenized (think of the ubiquity of mobile phones and social media) and so, it makes sense to bring communications technology together as a single subject as well.

As I type this, it is actually possible to get a Degree in Communications Engineering (as a single subject) from many universities worldwide. However, communications engineers frequently hold other Degrees such as electrical engineering, physics, telecommunications and/or computer science.

The sort of students that apply for courses like this (and subsequently work in the related areas) are generally logistically minded, tech-savvy people who are comfortable learning new skills and adapt quickly to new technology. Certainly, the money can be good for a decent engineer with a good reputation and an up-to-date skill set. Industries that rely on the expedient exchange of information (news networks, the stock exchange, big businesses and etc) should be the goal for the ambitious communications engineer (as well as the eager graduate).

Communications engineering is a vast and somewhat esoteric subject, because it combines so many different disciplines. Ideally, good communications engineers would be just as able to handle microwave engineering as they would a downed computer network, so it takes a smart cookie to be really good at the job.

Communications engineers are often quite business savvy as well. A big part of the job is dealing with clients or management, making presentations and working effectively as part of a team. Experience of modern business practice is not essential, but from the looks of things, it certainly helps.

The vast majority of communications engineers work for specific telecommunications companies and/or manufacturers, although some are self-employed as consultants or on fixed contracts.

According to Targetjobs.co.uk, typical job responsibilities for a communications engineer include: undertaking site surveys, agreeing to and staying within a client budget, staying up-to-date with technological information, problem solving (obviously!), creating test procedures, creating ‘worst case scenario’ plans for companies to follow and presenting companies/clients with the best way to manage their communication systems.

To put it simply, a two-way radio is a device that can both receive and transmit voice messages. In broader terms, it can be said that most wireless communication, and it may include cellular systems, fall under the definition. However, these days, two-way radio is a term to describe radio system for group call communication. The two-way radio comes in several technical names such as Public Access Mobile Radio, Private Mobile Radio, Land Mobile Radio and Professional Mobile Radio. These present times, two-way radios are often called “walkie talkies”. There are several kinds of two-way radio systems and some are able to make use of base and mobile configuration, while some re able to utilize a radio network infrastructure.

A typical two-way radio includes a PTT button, also known as Push-To-Talk button. The button activates the transmitter and the user simply needs to talk to the device to start communicating. The user must release the PTT button in order to receive transmissions from the other line.

A two-way radio is able to communicate with other radio devices. However, direct radio communication has very limited range. To overcome the problem, a radio network infrastructure may be used to extend the range of communications. The rest of the article is going to cover more details about how 2 way radios work and other useful information.

Receiving Radio Waves

Just like other forms of wireless communications, a two-way radio sends messages over the air. In order to achieve this, the antenna of a way radio contains a specific set of electrons. If the two-way radio features multiple channels, then there is specific sets of electrons are each channel. Whenever a radio transmission is received by the two-way radio, the electrons get excited. The electrons then create electrical impulses. Electrical impulses are then sent to a small processor, which will then convert the electrical impulses to words and sounds that can be understood by humans. The sounds are produced by the speakers within that two way radio.

Keep in mind that there are always radio waves are floating in the air. Because of it, there is always a nondescript sound that may be produced by the two-way radios. To solve the issue, a lot of two-way radios feature a “squelch” setting; and with it, the user can adjust the signal threshold for clearer communications.

Sending Transmissions

Two-way radios can also send messages across the air. The main idea is to convert the sound to radio waves. However, the defining characteristic about the way radio is its ability the convert back the radio waves back to legible sounds.

Whenever a user speaks into a two-way radio, a membrane within the device will vibrate as a response to the sounds. The vibrations are sent to the processor, which in turn converts them to electrical impulses and readies it for transmission.. Finally, the transmission is sent to the antenna which is then broadcasted in the form of radio waves. These radio waves are then received by another device and convert them back to a legible sound.

Multiple Channels

As two-way radios are getting more and more popular, it is possible for more than one party communicating in the same line or frequency. This can cause a lot of confusion and interference. To solve the problem, modern two-way radios are able to utilize multiple channels.

For a two-way radio to broadcast on multiple channels, the device must be able to generate radio waves in multiple frequencies. Furthermore, the device must be able to send frequencies with very little fluctuations. These fluctuations are actually caused by the transmitted voices. The fluctuations can be minimized through “frequency modulation”. The modulated transmissions are then sent to the device’s antenna.

The device must also excite the proper electrons. Once the proper electrons are excited, an outgoing radio wave is then produced.

These radio waves may be picked up by another device tuning into the same frequency. Furthermore, the device must be within range of the transmitting device. The range of two-way radio is usually determined by a couple of factors such as atmospheric conditions, radio’s battery power and the size of the two-radio’s antenna.

Whenever a device picks up the transmission, the receiving radio must filter the signals through an electronic filter known as a bandpass filter. Finally, the transmission is then converted back to sound.

Why Choose A Two Way Radio

The two-way radio is one of the earliest forms of wireless communication. However, in today’s modernized communication environment, a question arises – is the way radio a viable technology? The answer to that question is a yes. This is because the two-way radio has its own unique advantages that may not be found in other forms of wireless communications. Below are two of them:

Instant Communication – the ability to communicate between two or more parties almost instantly is one of the most defining advantages of the two-way radio. A user only needs to press the “Push-To-Talk” button and within seconds a receiver will be able to receive the audio messages. Furthermore, the entire system is set up around the idea of “quick call” and “quick receive”. This is the main reason why the organizations rely on the two-way radio technology for operational and tactical communications. The system can also make use of encryption technology for a more secure communication.

Group Communications

Another unique advantage of two-way radio is its ability to facilitate “group call” or “one-to-many” communications very efficiently. By efficient, it means that the user can communicate with one, hundreds or thousands at the same time. There is no need for a user to repeat the same message if he/she needs to communicate to more than one individual.

A two-way radio is one of the earliest technologies used for wireless communications. Even though it is a bit outdated compared to other forms of wireless communications, but the usefulness is still very applicable today. The main idea of how 2 way radios work revolves around on sending and receiving radio waves, which in turn is converted to legible sounds. The idea and technology behind two-way radio may be simple, but nevertheless it is still a very well-used form of communication in today’s world.

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

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

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

Communication is Instant

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

Group Communication is Possible With This Technology

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

Benefits of a Two Way Radio System of Communication

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

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

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

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

• Communication using the two way radio system is instant.

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

Conclusion

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

With a lot information around the internet about 2 way Radio’s it is hard to find the top and generally candid articles. here’s a piece of writing from a reputable website that i believe to be true, do not quote me on it but please read and enjoy

A two-tonne consignment aboard the ill-fated  MH370 flight is believed to comprise walkie-talkies, lithium ion batteries and their chargers.

The cargo manifest released in the preliminary report of the incident shows that the plane was carrying 200kg of the batteries while the balance is said to be “radio accessories and chargers”.

The revelation by Malaysia Airlines confirms a report by fz.com on March 25 that revealed that the shipper of the lithium ion batteries, walkie-talkies and chargers was Motorola.

Quoting a source at that time, fz.com reported that the goods were shipped from the factory’s facility in Penang.

The goods were sent by lorries to the KL International Airport, and based on the master air waybill, the items were sent from Penang on March 6.

Of the 2.4 tonnes that was shipped from the plant in Penang, only about 200kg comprised the batteries.

Though the cargo manifest and master air waybill indicated lithium ion batteries, it did not reveal that walkie-talkies made up the rest of the consignment.

MAS later said in a statement that they were “radio accessories and chargers”.

The air waybill prepared by NNR Global Logistics Sdn Bhd on behalf of its client, Motorola, showed that two loads were packed, one being 1,990kg for 133 pieces and another being 463kg for 67 pieces.

The batteries and accompanying goods were later shipped by NNR Global Logistics, while the balance divided into “13 packages”, were forwarded by Kerry Logistics (Malaysia) Sdn Bhd.

The cargo manifest showed the plane carried 9,947kg in three large shipments.

While mangosteens from Muar, Johor weighed the heaviest at 4,566kg and the 2,453kg worth of lithium ion batteries and accompanying goods (written up only as “consolidated”) are more or less accounted for, the other 2,250kg of “consolidated” items have sparked interest.

A source familiar with aviation forwarding industry practices said the mystery surrounding the cargo manifest and the exact loads that went onto the ill-fated MH370 can only be resolved if MAS revealed the house air waybills.

The source added that without the house air waybill and the packing list, the cargo manifest and the master air waybill were redundant because only those two documents would properly state the goods and the shipper.

“It is understandable that MAS cannot reveal the other two documents simply because they may not have it.

 “As for the house air waybill and packing list, the Customs Department, the freight forwarder and the shipper should come forward and reveal them,” he said.

Days after the Beijing-bound flight went missing along with 239 passengers and the crew on March 8, Malaysia Airlines chief executive officer Ahmad Jauhari Yahya said the plane was carrying 200kg of “small” lithium ion batteries.

He said the load was not considered hazardous as it was packaged in accordance to safety regulations.

In response, the aviation source said though the shipment contained batteries and declared as dangerous goods, they are within specified permissible levels.

“The dangerous threshold for lithium ion batteries is not measured by its weight but its watt per hour measurement. For instance, a handphone probably would measure 100 grams watt per hour which is not lethal.

“The watt per hour measurement indicates the battery activity by the hour,” he had said while cautioning that forwarding companies and shippers often failed to declare “hidden dangerous goods” in the shipment.

These include flammable liquids, lubricants, corrosive and oxidising materials that could and have resulted in fires onboard flights, he said.

This article is posted by the faithful permission of earpiece.co.uk, which is the original website. please get agreement from that website before reposting this editorial.

Earbuds are headphones, typically made out of a hard plastic material, that fit inside the ear, just outside of the ear canal. These aren’t the same thing as ear canal headphones, which have a rubber tip and seal within a listener’s ear canal.

Several portable music devices, like mp3s and Personal Digital Assistants (PDAs), come with earbuds when the device is purchased. Earbuds are a less expensive alternative to ear canal headphones or other listening devices. Consumers tend to purchase earbuds for their convenience, as they are easier to carry around than other headphones because of their small size.

This style of headphone also tends to be more inexpensive than other kinds, like ear canal headphones, circumaural headphones that fit outside the ears, or the supra-aural headphones that have pads that are placed on top of the ears, rather than around or inside them. Circumaural headphones are typically used in recording studios and supra-aural headphones can still be purchased at some stores, though these kinds of devices have given way to headphones that fit within the ear.

Because of the design of earbuds, there can be a few drawbacks to owning them as opposed to owning another style of headphone. First, the rigid design of earbuds can sometimes make it difficult for them to fit comfortably inside a listener’s ear. If they’re too large or too small, they can either slip out of the ear or won’t fit inside it at all. Another problem reported by consumers is that because earbuds don’t seal the ear canal, the sound quality is muddled through other ambient noises.

Essentially, most earbuds work the same as other headphones and the set-up is relatively simple. Wires move up from the electronic device that is putting out sound, such as an mp3 player. These wires connect to a voice coil. The coil is attached to a cone, which is flexible and plastic. A magnet is attached to the back of the earbuds. When sound passes up through the wires and to the magnet, the voice coil becomes electromagnetic and moves up and down with the sound. The cone then pushes the sound out through the earbud and into the listener’s ear.

When listening to earbuds or any other type of headphones, physicians recommend to keep the volume at a reasonable level, as research had proven that prolonged exposure to high noise levels can lead to permanent hearing loss. Prolonged listening to loud noises, including music, puts unnecessary stress on the hairs in the cochlea. This causes permanent damage to the hairs and can eventually lead to hearing loss.

A Czech-Republic based security firm (Avast), have ruined everybody’s fun by pointing out that, even when your old phone is subject to a full ‘factory re-set’, those ‘special pictures’ your lover sent you can actually be retrieved by a third party.

Now, I imagine that there are two types of people reading this article:

People who are now wondering if their naked selfies are being perved over by complete strangers at this very moment (it is possible, I’m afraid).

…And the people who are expectantly clutching their second-hand phones and waiting for me to get to the bit where I explain how to obtain these pictures (shame on you, but hang in there, we’ll get to it in a bit!).

Well, whichever you are, you should know that the firm used publicly available forensic technology to extract, not only naked selfies, but ALL SORTS of other data from second hand phones they purchased on eBay (however, they were clearly most excited about the selfies – computer nerds don’t get out much, after all).

According to experts, the only way to PERMANENTLY delete these images from your phone is to destroy your phone.

Now, if you’re the smug type of reader, who thinks ‘I never took a naked selfie, so I’m in the clear’…Well, I’m here to tell you that you may be facing an even more embarrassing problem than that of a stranger on the Internet getting a gander at your goodies, because other data extracted from the test phones included texts, emails and Google search data.

I’m also here to tell you that you’re a pretty boring person.

I’ll bet you wish they’d been distracted by your bits now, don’t you?

Of the 20 phones examined by Avast, about 40,000 photos were extracted and about 750 of them depicted women in the nip (or near to it), whilst 250 or so depicted (to quote Avast) “the previous user’s manhood”.

According to Avast, “Deleting files from your Android phone before selling it or giving it away is not enough. You need to overwrite your files, making them irretrievable.”

Even then, older smartphones sometimes only erase the indexing of the data and not the data itself. To make matters worse, the tools required to retrieve this data can be easily downloaded from the Internet (and no, I’m not telling you where!)

So, the moral of the story appears to be that, if you want to continue getting those ‘special messages’ from that ‘special someone’ then for Pete’s sake…Don’t show them this article.

Some of these pro writers on the internet are at a really top level that i wonder if any of them have ever printed a paperback? well every so often i like to spotlight these first-rate articles and here’s one i found fascinating the other day.

Two-way radio communication at a local technical school would greatly improve school security, according to one local official.

Lenape Technical School Special Programs Coordinator Carla Thimons further explained the need for such during discussion on the Manor Township school’s $18,000 Pennsylvania Department of Education Safe School Initiative Competitive Targeted Grant award.

“These will truly help us feel better about safety overall, because communication is key,” Thimons said.

She said several programs at the technical school provide a unique challenge where areas of the building would not be able to listen to announcements over the public address system, and the radios would provide necessary internal communication with teachers and staff.

Thimons said the grant funds were accepted by the Joint Operating Committee last month, and funding received, but the radios have not been purchased yet. She explained officials want to coordinate efforts with the Armstrong County Department of Public Safety to ensure that communication will be loud-and-clear.

“We want to determine the best purchase,” Thimons said. “We have an idea in mind what we want, but we want to coordinate with (the Department of Public Safety.)”

Radios are to be expected to be carried in the school hallways by officials by the start of the 2014-15 school year.

Thimons, who has been Special Programs Coordinator for 10 years and was previously the technical school’s principal, coordinates special education, grant writing and safety procedures at the school.

Besides the two-way radios, Thimons said school officials are planning to hold school wide drills, including a mass-evacuation drill.

Joint Operating Committee members also unanimously approved the hire of Night Watchman Samantha Walker, retroactive to March 7.

Principal Karen Brock last month said the school used to have night watchmen, but another one needed to be hired to replace that individual.

Armstrong School District also received Safe School Initiative Competitive Targeted Grant funding in the amount of $25,000, and put the money toward the purchase of new and updated security cameras “as another layer of security throughout the district,” according to School Superintendent Stan Chapp in March.
Director of Technology and Information Services Anthony Grenda said about 16 surveillance cameras will be added to the interior and exterior of Elderton and Shannock Valley Elementary Schools. He hopes those cameras are installed by the end of the current school year. Several have already been installed, he said earlier this week.
Apollo-Ridge and Leechburg Area School Districts also received $25,000 in grant funds.
Earlier this year, Armstrong also received $40,000 in the state’s Safe Schools Grant Program for utilization of a school police officer. Those officers have also been already utilized throughout the district.
The Lenape Tech Joint Operating Committee meets again Thursday evening, beginning with a 6:30PM public budget session at the school.
