two way radio accessoriesThe walkie talkie radio was developed during the Second World War to allow military personnel to communicate effectively while in combat situations. Strangely the term walkie talkie actually refers to the backpack two Way Radio models carried by troops, the handheld varieties being known as handy talkies amongst the troops. Today the walkie talkie radio is used in all manner of industries and in the home and like so many electrical devices has shrunk considerably from the original cumbersome models used throughout the war. In general the walkie talkie has a mouthpiece to speak into and a speaker to listen to messages; modern variants however also have earpieces for discreet applications.

Predominantly the radio comes in two types; usually these are referred to as licensed and unlicensed in the industry. Licensed walkie talkies have a specific radio frequency that communications are transmitted across; typically this frequency is isolated purely for that set of radios. An example of this would be the radios used by racing pit crews in order for them to communicate with each other, the team director and the driver whilst he is out on the track. Unlicensed varieties are normally available in most electronic stores. These are not given a specific frequency and as such as susceptible to problems with cross communication from other radio devices. Because of these problems unlicensed models are normally cheaper than licensed versions.

Considering the type of walkie talkie radio to purchase can be difficult with such a large range on the market today. Firstly it is important to assess the purposes the radios will be used for; for instance, hikers may wish to use an unlicensed model while security personnel would almost certainly need to look at licensed devices. As with any purchase it is important to research the different technologies out there before purchasing. With features such as weather channels, head set transceivers and wrist communicators there is a wide selection to choose from. At this stage it is important to stick to your needs and not buy a device with features that will never be used.

The distance that radios will have to cover is also an important consideration. Anything fewer than two miles is normal although if the distance is greater than five miles, licensed models should certainly be looked at as a more appropriate option. If it is likely that multiple users will be operating the devices a compatibility system will be required. This will allow communication between many parties and will eliminate static and interference. The power supply is naturally an important factor and should be considered carefully, rechargeable models are perfect for uses with a ready power supply but for applications away from settlements changeable batteries are a better solution.

When using the device it is important to learn how to scramble the radio communications. Many models use a voice scrambler to keep messages private while some have sub channels that allow for private communications within an existing network. As part of this it is always important to realise what is being said when speaking through the walkie talkie, conversations should be kept brief and specific to the task, anything confidential should be kept to face to face meetings.

Many thought that the walkie talkie would soon become obsolete at the advent of the mobile phone. This is a fallacy however; there are certain instances where the two way radio is far more useful, such as in areas with little or no network coverage and situations where the time lag on cell phone communications is not preferable. Hopefully this information has given an idea of the uses of walkie talkies and how to select the right model for different purposes. As technology improves it is doubtless that these devices will become ever smaller and more adept at answering people’s communication requirements.

2 Way Radios for Golf Club Management

2 way radio frequencyWow. The newest 2 way radio multi pack is incredible. I mean it is just so gorgeous so sophisticated. I pity those who grew up without the communication devices in fabrics and clothes.

With a typical 18 hole golf course covering 100 acres, everyday communications between teaching professionals, pro-shop staff, course managers, greenkeepers, maintenance staff, irrigation experts, caddies and timekeepers can often be both costly and time consuming especially if mobile phones are used.

By contrast, Walkie Talkies allow staff to communicate instantly and effectively, saving costs, improving efficiency, ensuring resources are mobile and available where needed to ultimately deliver a better experience to players.

The beauty of two way radio communications is that once you have received your license to operate, all communications between users are instant and free save the cost of the equipment; these are just two examples from a wide range of benefits that two way radio communications provide to golf club management.

With the advent of trunked digital two-way radio systems, this ability to communicate by voice and data has been significantly improved in terms of quality, range, security and enhanced functionality.

Let’s look at some other benefits in more detail

Management of Health, Safety & Security
Faster more effective response to emergency situations such as illness and injuries on-course.
Warn players and staff of the risk of storms and lightning.
Provide on-course staff with ability to report security issues.
Feedback on course condition
Respond instantly to player feedback on the condition of the course.
Reporting breaches of course etiquette
Allows staff on course to report to club management on breaches of club rules and etiquette.
Improved Tournament Management
Instantly connects tournament management with timekeepers, the pro-shop/player registration desk, practice area, car parks, referees, marshals, officials, caddies and other on-course staff.
Managing pro shop resources
Ensuring teaching professionals are kept updated on arrivals, caddies are organised, carts are available and players’ equipment is to hand.
Increased sales
Improve stock availability on beverage carts, at on-course catering outlets and pro shop.
Improved player experience
The seamless management of players from arrival at the club, through the pro-shop, during play and at the clubhouse.

Equipment selection

Having established the range of benefits that two-way radios can offer a golf club, the next consideration is the selection of equipment.

Given the large area and topography of golf courses, a number of factors come into play.

First, is there a requirement for DP2600 two way radio communications to cover every part of the course including inside buildings and for different user groups to have their own channels?

Analogue two way radios have been in use for many years and while the functionality of analogue equipment has improved the technology has inherent limitations:

Analogue or Digital two way radio. Which is better?

Rather than describe any shortcomings of licensed or license-free analogue two way radio, which will in any case only be relative to specific applications and circumstances, the table below details some of the advantages of the Kenwood NEXEDGE® digital two way radio system to illustrate the extended benefits of digital technology, especially if you are an existing analogue user:

Increased range
Digital transmission provides a stronger signal at the extremities, giving a much greater usable range.
Improved speech quality
The AMBE+2™ Vocoder employed by NEXEDGE® is a state-of-the-art voice compression digitization technology that offers superior clarity at varying signal strengths. This reduces the number of lost or misinterpreted calls caused by the effects of external background noises including environmental noise levels – especially important in windy conditions.
Increased security
Improved security against eavesdropping via NXDN® digital air interface. NEXEDGE® also includes NXDN® voice and data scrambling for security against external threats while providing confidentiality within the same system and talk group.
Reduced bandwidth consumption
All NEXEDGE® equipment operates on 25 & 12.5 kHz in analogue mode and 12.5 & 6.25 kHz in NXDN® digital modes – effectively doubling or quadrupling the number of channels available.
Direct calling
Set up your NEXEDGE® system to allow radios to call each other directly, without other radios hearing or being aware of the conversation.
Text Messaging
NEXEDGE® radios can be used to compose and send short text messages using the keypad (or select from a list of pre-programmed messages).
Feature rich

A NEXEDGE® system can be configured to provide GPS tracking, lone worker security, over the air programming, remote kill/stun, man down and radio to telephone integration.
Extended battery life

NEXEDGE® hand portable radios/walkie talkies offer low power consumption compared to analogue radios, important for all day golf tournaments.
Digital/Analogue Mixed Mode

Unlike most other digital radios, NEXEDGE® Digital Two-Way walkie-talkies feature an Analogue/Digital Mixed Mode which allows them to communicate automatically with any existing analogue radios whatever the make; providing a straightforward and economical way to use existing radios while migrating to the benefits of digital without compromising service quality and reliability.
Future Proof

NEXEDGE® digital two way radio systems are designed to grow with your requirements starting with hand-portable walkie-talkies and mobile units for one to one communications with the ability to scale the system up to a trunked networks able to accommodate large user groups spread over wider areas.
Durability

All NEXEDGE® hand portable walkie talkies conform to US MIL-STD-810 C/D/E/F/G for ruggedness and durability and are IP54/55 Water & Dust Intrusion rated, making them ideal for operation in open and harsh environments.
Discrete operation
You can connect a discrete microphone and earphone accessory to any NEXEDGE® hand portable radios/walkie talkie so transmissions cannot be heard by others, important while on-course during a golf tournament. NEXEDGE® hand portable radios are also small and light making them easy to carry or keep hidden out of view.
