At just 19, John T. “Jack” Hickey was the first to report VE day to his unit while working {radio|{2|Two} way Radio|Walkie talkie} communications for the U.S. Army.
Mr. Hickey served in Europe during World War II, and was a witness to history. He arrived in time for the brutal Battle of the Bulge, and later provided security during the Nuremberg Trials.
While overseas, the younger Mr. Hickey would use technology — the field that would guide his life — and employ skills he had learned as a teen lab assistant at Motorola.
Mr. Hickey, 88, a door-to-door car-radio salesman who would become chief financial officer at Motorola, died June 7 at his Glenview residence after a brief illness.
From building Motorola’s first semiconductor plant in Arizona to leading long-term planning events, Mr. Hickey played a key role in the company’s evolution. He had lifelong ties to the company; Mr. Hickey’s father was a friend and adviser to Paul Galvin, founder of Galvin Manufacturing Co., which became Motorola.
Mr. Hickey was involved in the advances Motorola made during his 50-year career, “from the big radios to the transistor radios that we used to be able to slip in our pockets when we were in school, to huge TVs to small TVs,” said Kathy Barrie, one of Mr. Hickey’s five children.
Mr. Hickey had one of Motorola’s earliest cell phones, the size of a couple of bricks.
He loved technology. The father of five once took his family to the Motorola Museum in Schaumburg for a reunion to show off the kind of {radio|{2|Two} way Radio|Walkie talkie} he used in the war: “My dad pointed out the model of the radio, which would be like lugging around an oxygen tank. It was just huge and heavy,” Barrie said.
Mr. Hickey had already met the love of his life before shipping out. Her name was Joanne “Jaye” Keating.
“My mother was a real beauty,” said Barrie. “Dad pursued her from the other side of the world, writing her letters and letters. When he came back, he just set his sights on mom.”
The two married in September 1949.
“I have never seen two people be such units. They just were all the way through, just ridiculously in love with each other,” Barrie said.
The two traveled the world as Mr. Hickey rose in the ranks at Motorola; there were business trips to Japan and China, to Korea and the Philippines.
They visited Normandy in 2006 — one of their last big trips — where some of Mr. Hickey’s WWII history came to light.
“It was a very profound experience for him,” Barrie said.
Mr. Hickey didn’t talk about his military service until his later years. When his son Jim brought home a middle school assignment asking his father to describe his service in World War II, Hickey just said “no,” his son recalled.
But memories came flooding back in his later years. Barrie said she noticed her dad’s calendar just days before he died. He had marked down VE Day on May 8 (for “Victory in Europe,” marking Nazi Germany’s surrender) as well as D-Day on June 6.
“He was really thinking more about those days,” Barrie said.
Even after retiring, Mr. Hickey kept up with technology. He read books and newspapers on iPads. He loved emailing. And he loved Google Earth.
“He’d just marvel at what the industry was capable of. He really had such zest. He did in most things. He was an enthusiast of the highest degree. He loved new things,” Barrie said.
In retirement, Mr. Hickey spent time with his family. He also volunteered on behalf of his alma mater, Loyola Academy, and was on Motorola’s board of directors for 10 years after he retired in 1985.
He became very nostalgic in his later years, always saying “God Bless you,” said Jim Hickey.
“He was a man who very much recognized the blessings that his life had. He was a religious guy, and we laugh about this, but in his last year, he would say ‘God bless you’ about 300 times a day,” he said.
Besides his wife, Mr. Hickey is survived by children Kathy Barrie, John, Mike, Jim and Roger, 20 grandchildren, two great-grandchildren and one great-grandchild on the way.

SEPURA STRIKES RICH SEAM IN AUSTRALIAN MINING SECTOR

This article is posted by the faithful agreement of two way radio neck mic.co.uk, which is the original site. please get consent from that blog before reposting this short article.

Digital radio technology from Sepura in Cambridge UK is gaining significant traction in the Australian mining sector.

Sepura TETRA motorola SL4000 two way radios have been chosen to operate on the first long haul railway radio network owned by the major Australian mining organisation Fortescue Metals Group (FMG).

The world-first contract was won in conjunction with Radlink, one of Sepura’s longstanding and experienced partners in Australia.

FMG first adopted TETRA technology in 2010 as a future-proof company-wide standard for all communications further to a successful pilot site roll out at its flagship iron ore mine of Christmas Creek in the Pilbara region of Western Australia.

The TETRA system now covers all the company’s operations and provides a unified communications platform to enable the smooth running of activities across all facets of the business.
The new TETRA system deployed by FMG’s rail network comprises 24 sites, over 400 km of rail roads and more than 800 Sepura TETRA terminals.

Doug Bowden, senior business development manager at Sepura said: “In the last two years we have witnessed the growing adoption of TETRA by the mining sector in Australia, Europe and also in the American continent and believe that Sepura has played a significant part in stimulating this growth.”

Airports have become remarkable places, entire communities, employing tens of thousands of people within their perimeters, and covering areas measured in square miles, operating 24 hours a day, 365 days a year.

Running an airport can be likened to running a large town, for instance the three hundred companies operating within London Heathrow Airport employ 80,000 people, which is roughly equivalent to the population of Warrington, a large conurbation in the UK. This is hardly surprising when they serve over 65 million passengers arriving at, departing from, or transferring through the airport.

Clear, reliable and effective SL4000 two way radio communications of both voice and data between diverse teams in an airport is not just important, it’s mission critical to operational efficiency, business continuity, safety and security.

In the past, companies within airports operated as separate entities and developed their own two-way radio systems to allow them to communicate with their clients, typically airlines; while in turn, airlines needed to communicate with both their suppliers and their own teams.

This led to a proliferation of isolated communications systems and resulted in huge inefficiencies and a high risk to the resident airport community and passengers in the event of an emergency or disaster.

In recent years however, this situation has changed across the world’s airports with investment in integrated solutions to allow cross communication between individuals and user groups operating at desks, on foot or from vehicles, including:

Airport management
Airlines
Airline agents
Ground services
Flight and cabin crew
Engineering
Construction
Maintenance
In-flight catering
Retail and catering
Hotels and Car Parks
Transfer services
Baggage handling
Cleaning services
Freight handling
Border control
Security teams
Safety teams

As you would expect, Kenwood analogue two-way radio communications equipment has been in use at many of the world’s leading airports for years and now with NEXEDGE® digital two-way radio systems incorporating hand-portable walkie-talkies, mobile units and repeaters operating in fully scalable digital trunked systems, more airports than ever are migrating to the outstanding coverage, flexibility and security that digital two way radio offers. Recent NEXEDGE® Airport installations include the six largest airports in Turkey and Vnukovo Airport in Moscow.

How To Use Distant Measuring Equipment Within A Flight Planner

what would you say if this website About keyword was one of the best one we found this week, would you suspect us?

two way radio setsWhat is distance measuring equipment that is used within a flight planner?

Distance measuring equipment is a transponder based Walkie Talkie navigation technology that measures slant range distance by timing the propagation delay or VHF or UHF radio signals. Developed in Australia, it was invented by Edward George Bowen while employed as Chief of the Division of Radio physics of the Commonwealth Scientific and Industrial Research Organisation (CSIRO).

Another engineered version of the system was deployed in the early 1950s operating in the 200 MHz VHF band. The Australian domestic version was referred to by the Federal Department of Civil Aviation as DME (D) and the later international version adopted by ICAO as DME.
DME is similar to secondary radar, except in reverse. This system was a post war development of the IFF systems of World War II. To maintain compatibility, DME is functionally identical to the distance measuring component of TACAN used within a flight planner.

Operation
Aircraft use DME to determine their distance from a land based transponder by sending and receiving pulse pairs. These are two pulses of fixed duration and separation. The ground stations are typically located with VORs. A typical DME ground transponder system for en-route or terminal navigation will have a 1 kW peak pulse output on the assigned UHF channel.

A low power DME can also be co-located with an ILS glide slope antenna installation where it provides an accurate distance to touchdown function, similar to that otherwise provided by ILS Marker Beacons.
Distance calculation and accuracy used within a flight planner
When using a flight planner, a radio pulse takes around 12.36 microseconds to travel 1 nautical mile to and from and it is also referred to as a radar mile. The time difference between interrogation and reply 1 nautical mile minus the 50 microsecond ground transponder delay is measured by the interrogator’s timing circuitry and translated into a distance measurement (slant range) which is stated in nautical miles and then displayed on the cockpit DME display.

The accuracy of DME ground stations is 185m. Its important to know that DME provides the physical distance from the aircraft to the DME transponder. This distance is often referred to as ‘slant range’ and depends trigonometrically upon both the altitude above the transponder and ground distance from it in a flight planner.

MOTOTRBO Powers Shop Watch Scheme for £40 Million Antonine Centre

Can’t get over how cheap the walkie talkie baby monitor is now, an amazing deal for any top-end product!

Antonine Centre Chooses Customisable, Dependable, Next-Generation Communications with Increased Coverage and Enhanced Voice Clarity

The Antonine Centre in Cumbernauld, which opened in 2007 has 42 shops in 350,000 square feet of retail space and 3,000 parking spaces and is one of Scotland’s newest retail and leisure complexes. Part of an urban regeneration initiative, Antonine has been hailed by councillors as signalling the rebirth of the town Centre and has led to the creation of more than 600 jobs. Retail analyst CACI estimates that the creation of the new mall will increase spend in Cumbernauld town centre by as much as 84%.

Deterring Retail Theft with Instant, Secure, Discreet Communications

The Antonine Centre needed a reliable communications system to enable members of its shop watch scheme to alert each other and the Mall Security Officer to the presence of known criminals or troublemakers. Shopalert was created to help protect retailers against the rising cost of shoplifting by enabling stores to work together to tackle criminals.

The Antonine Centre was already using Motorola Professional Series analogue radios to streamline some of its routine, day-to-day activities. Cleaning operatives, security personnel and the managerial team were using Motorola Professional Series radios to keep in touch with colleagues throughout the 75-hour trading week.

The Centre now wanted to extend its use of two way radios to build a system that could provide the most effective deterrent against groups of well-equipped, fast-moving thieves.

MOTOTRBO Offers Better Value for Money with Improved Coverage, Greater Operational Flexibility and Backwards Compatibility with Analogue
Digital two-way radio was chosen to provide a secure, discreet communication system with no risk of transmissions being compromised by eavesdroppers. The Centre’s local Motorola Authorised Dealer demonstrated how MOTOTRBO digital radios could provide greater coverage and improved audio clarity than analogue and enable users to make both one-to-one and group calls. The increased battery power would extend battery life by up to 40%, enabling the radios to be used throughout the entire 11-hour trading day without recharging.

The radios were pre-programmed to users’ needs by the Centre’s Motorola Authorized Dealer, which ensured a rapid set-up and seamless go-live. User training took only 20 minutes thanks to the cellular look and feel of the handsets. MOTOTRBO handsets cost around 10% more than analgoue, but their higher specification and wider feature set meant they could meet Antonine’s needs more effectively and offer better long-term value.

Shopalert was an immediate success, with 10 of the larger outlets, including Next, River Island, Woolworth’s, Dunnes Stores, TK Maxx, Dorothy Perkins and Birthdays, joining immediately. Each

shop has a MOTOTRBO DP 3400 hand portable that is used by managers or door security staff to alert all other scheme members and the Mall Security Officer simultaneously to troublemakers. Around 70% of all calls made are broadcast to all users but retailers can also request a one-to-one call with the Mall Security Officer if they want to discuss an incident discreetly, without alerting all users. Pushing the blue button

on the side of the radio sends a pre-determined text message to the security officer asking for a private call. The on-duty security controller carries a MOTOTRBO DP 3600, which has an alphanumeric display enabling the controller to identify the caller instantly.

Around 30% of transmissions are one-to-one and caller identification is a particularly useful feature for the Antonine Centre. Knowing who is calling

enables security staff to respond more rapidly to any situation that arises. They can also take advantage of MOTOTRBO’s interoperability between analogue and digital to ask the CCTV controller using the Motorola Professional Series radios to train cameras on any particular store or alert the police immediately if required

If an emergency situation arises, users can press the orange button located on top of the MOTOTRBO radios. This transmits their identity to the controller and all other radios which emit an audible signal to alert users. The radios can also be deactivated remotely by the controller to protect against theft and misuse. If a lost radio is subsequently found, it can be revived over the air by the controller.

Around 40 calls each day are made by the mall security officer and three or four by each Shopalert member. Most transmissions last only 10-20 seconds but some longer calls last for up to one minute. MOTOTRBO’s high-quality audio transmission virtually eliminates background noise and ensures that there are no black spots across the entire complex. Speech clarity is excellent, there are no scrambled messages, and all communications are transmitted loud and clear. The ability to transmit messages securely, knowing that there is no risk of them being intercepted, is a major advantage over analogue and of considerable benefit in the fight against crime.

The wider range of digital reduces hardware purchasing and operating costs by eliminating the need for a base station to provide coverage across the entire shopping area and its three outlying car parks. MOTOTRBO’s broad feature set means that new functionality can be added incrementally as the shopwatch scheme’s needs expand, making it a scalable, future-proofed, cost-effective solution.

Shoplifting Cut as 30% Join Shopalert Immediately and a Further 20% of Retailers Set to Join when all Outlets are Fully Operational

Shopalert has been very successful in deterring theft at the Antonine Centre where notices announcing the crime prevention initiatives in place have been displayed in every participating shop. Since going live with the MOTOTRBO radios very few instances of attempted shoplifting have been reported. The scheme is currently live in 30% of the stores that are already open, a figure that is set to increase to 50% when all outlets are fully operational. Most non-participants are either very small stores or shops that provide a service rather than sell goods, such as

hairdressers, where the risk of theft is not a significant problem.

Digital transmission prevents the risk of professional shoplifters with frequency scanners being able to eavesdrop on calls. The improved speech clarity

of digital over analogue means that messages get through first time, even against the constant

background noise of a busy mall. MOTOTRBO’s ability to enable callers to make one-to-one as well as group calls ensures that users who are not part of a call remain undisturbed.

MOTOTRBO’s interoperability between analogue and digital means that the Shopalert radios could be programmed to operate with the Motorola analogue hand portables used by cleaning staff, security

and Centre managers. MOTOTRBO will ease user migration from analogue to digital in the longer term.

Using the VHF omnidirectional range in a flight plan

Well ladies and gentlemen, i’ve the second outstanding communication devices corp piece of writing for you to read, i know, you don’t have to thank me all, just add a social like to the short article to show your appreciation.

2 way radio yaesuWhat is a VHF omnidirectional range used in a flight plan?

VOR which is short for VHF omnidirectional Walkie Talkie range, is a type of short range radio navigation system for aircraft in a flight plan, enabling aircraft to determine their position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons, with a receiver unit.

They use radio frequencies in the very high frequency (VHF) band from 108 to 117.95 MHz. Developed in the US beginning in 1937 and deployed in 1946, VOR is the standard air navigational system in the world used by bother commercial and general aviation. There are about 3000 VOR stations around the world.

History and background
Developed from earlier Visual-Aural Range (VAR) systems, the VOR was designed to provide 360 courses and from the station, selectable by the pilot. Early vacuum tube transmitters with mechanically rotated antennas were widely installed in the 1950s and began to be replaced with fully solid state units in the early 1960s.

They became the major radio navigation system of the 1960s when they took over from the older radio beacon and four course system. Some of the older range stations survived, with the four course directional features removed, as non directional low or medium frequency radio beacons.

Features used for a flight plan
VORs signals provide considerably greater accuracy and reliability than NDBs due to a combination of factors. VHF radio is less vulnerable to diffraction or course bending around terrain features and coastlines. Phase encoding suffers less interference from thunderstorms.

VOR signals offer a predictable accuracy of 90 meters, 2 sigma at 2nm from a pair of VOR beacons; as compared to the accuracy of unaugmented GPS which is less than 13 meters. VOR stations rely on the ‘line of sight’ because they operate in VHF band so if the transmitting antenna cannot be seen on a perfectly clear day from the receiving antenna, a useful signal cannot be received.

This limits VOR (and DME) range to the horizon or closer if mountains intervene. Although the modern solid state transmitting equipment requires much less maintenance than the older units, an extensive network of stations, needed to provide reasonable coverage along main air routes, is a significant cost in operating current airway systems in a flight plan.

Cell phone technology advances at a mind-warping rate. But cell phones are still just really fancy Kenwood radios, and they have an Achilles heel — they’re completely helpless without a network of nearby cellular towers. Walkie-talkies, though? These old-school radios make short-range wireless communications possible in places where cell phones go to die.

Walkie-talkies are wireless, hand-held radios that are small enough to take just about anywhere. They look a lot like cordless phone handsets, with a body that includes a microphone and speaker, as well as an antenna. Unlike a phone, though, a walkie-talkie’s speaker and microphone are placed right next to each other, and the speaker is much louder, so that anyone within earshot can follow the conversation.

Walkie-talkies are battery-powered transceivers, meaning they can both send and receive radio messages. They have a half-duplex channel, which indicates that only one walkie-talkie on a channel can transmit a signal at one time, although many radios can receive that same signal. In other words, unlike your phone, in which both parties can interrupt or add to the conversation in a ceaseless flow of sound, walkie-talkies use a push-to-talk (PTT) system — you have to press a button in order to speak, and you have to release that button to hear sound coming from other units.

Because you don’t have to dial a number each time you want to transmit, walkie-talkies are quick and easy to use. And best of all, they don’t rely on finicky cell phone signals. The handsets transmit directly to each other, so they still work when cell networks fail during natural disasters or power outages. They’re designed primarily for short-range communications, in which groups of people are within a few miles of each other.

Businesses use walkie-talkies so that employees can chat efficiently in and around their indoor and outdoor structures. Wilderness lovers tote walkie-talkies so that they can keep in touch during hiking or hunting trips out where cell phone cover age is non-existent. Even baby monitors employ one-way walkie-talkie technology, so that you know if Junior is sleeping peacefully or attempting escape.
