Not very many people are familiar with HD radio so I will first define it and it’s possibilities. The number of people with a HD radio is very small. Few people even know what HD stands for. Most simply think that it is high definition.

The original definition was hybrid digital. Some have said that it is now a brand name for the inventing company ( iBiquity Digital Corp.). The common use seems to be simply HD radio and defines the digital radio that captures the HD signals. The use seems to be more of a brand than anything else.

The radio stations like it because they can get many more broadcasting stations. This is part of the digital revolution that is occurring in the world today. The digital signal is compressed and bundled with the following signals: AM , FM, HD, HD2. The AM and FM signals are analog and digital. These are broadcast as a bundle but it requires the special HD radio to receive the digital and HD signals.

When or if the digital signal is lost, the radio reverts back to the analog signal. The AM digital signal loses its static and buzz and produces a sound that is very much improved over the analog signal. The FM digital signal produces a sound that is very close to CD quality. The question most people ask is are the people willing to pay the high price for a HD radio? These cost between $100 and $600 and are made for the table top or installed in a car.

The public likes their mp3′s and small portable radios. One can get a portable AM/FM for $15. The cost should come down if many people get the HD radios. Many or most NPR stations are going to the HD broadcast format. Most of the large stations are also changing to the new format. The cost is reasonable to convert to this format and the user fees to iBiquity must be reasonable as most stations are changing.

iBiquity might have improved the roll out by forgoing any fees until the usage was very high. The industry must have confidence in the system though since so many are changing to this format. The critics say that the technology has not been proven and may not work. Supporters say how can one loose by improving the sound to digital everyone wins.

This is the most improvement in radio sound since the introduction of FM stereo nearly fifty years ago. The government has forced TV stations to go digital. This also allows for high definition television for even better reception.. The government is not forcing radio to go digital but they are doing it on their own to improve reception. My opinion is that the hardware receivers will need many improvements before everyone is going to flock to the electronics store to buy their own. The size and features along with the price needs improving.

The technology for HD radio is here and looks great on paper. Will people turn off their satellite subscription and mp3′s and Iphones to go to HD radio? It could be a slow process but when it really catches on, it could take off.. The world is moving much faster in the digital world than it did in the slow days of AM and FM.

Before embarking on to write about the features and advantages of two way radios, it would not be out of place to first explain what exactly are two way radios. Well, they can be termed as transceivers that possess the capability to transmit and receive voice signals. It has a push to talk button that gets the device activated. Also popular as walkie-talkies, this hand held two-way device is available in mobile and stationery base configuration. It would be interesting to know that earlier this device was used exclusively by defence forces and police, though it is now increasingly finding favour with the civilian population.

Increased use of these two way radios have led to more and more innovation being introduced into the device. New models are being launched and every new model include some new feature, which has increased its popularity manifold. Two way radios include several channels as well, and the number of channels available depend on the type of radio being used. For example, there are 23 channels in GMRS (General Mobile Radio Service) and 14 in FRS (Family Radio Service).

There are several other features as well that go a long way in making two way radios popular. Their batteries, for example, are extremely durable. Also, there are different sets for different people. People who use these radios abundantly should go in for Nickel Metal Hydride or Nickel Cadmium batteries that can be recharged. Where as people who use it sparingly should opt for AA and AAA alkaline batteries. Then, two way radios can be easily carried any where. These days, many radios provide their users with weather forecast by meteorological department as well.

With so many outstanding features, it rarely should come as a surprise to anyone that two way radios have become so popular amongst the masses today.

Alternatively being called as walkie-talkies and even dispatch radios, two way radios are hand held mobile communication devices, which evolved out of the radio transmitters and receivers used by naval and army units in the early 20th century. As the world moved ahead in style and things progressed in every areas, the bulky radio equipments gave way to small and effective portable communication devices.

Coming out of the closet, these communication devices have gone through some pretty commendable research and development processes. Two way radios can be classified into various categories based on their abilities and the features they contain. But, mostly these wireless communication devices differ on the basis of their radio signal channels.

American telecommunications legend Motorola has attained phenomenal success in the field of two way radios courtesy of a wide variety of these hand held devices. Some of the radios even had push to talk buttons to get connected right away. With their efficiency and accessibility, these devices can actually sound as better options than mobile phones in some instances.

Two way radios of the present times have improvised much on their abilities as more and more manufacturers have applied their technology to capitalise on the rising popularity of these devices. The obsolete two way radios worked on the ordinary simplex mode, which simply allowed transmission of signals by a station as the frequency was used by all the users. This moved on to the full duplex mode, which allowed transmission and reception at the same time.

Walkie-talkies are tools that enable verbal communication with other people using the same equipment. Two way radios can be said to be the advanced version of walkie-talkies and function the same way as the later does. Describing it straight, two way radio is like a radio that transmits as well as receives voice contents, unlike a broadcast receiver, which only receives the voice content.

Usually, there are two types of two way radios available today. The first operates on Family Radio Service (FRS) while the second operates on General Mobile Radio Service (GMRS). FRS radios are for personal usage and are quite inexpensive. If weather is favourable, it can transmit signals up to a maximum distance of 2 miles. To own as well as use it, one doesn’t need a license. GMRS radios are, on the other hand more expensive than FRS, and can transmit signals to a maximum distance of up to 10 miles. These radios transmit at pretty high power levels and require a GMRS license to be operated.

Gradually being used in diverse fields, two way radios have several features attached with them. Such radios give users an option to use private code to protect the system from being caught by any other radio users. Some of the expensive radios sets have the system of reduced eavesdropping, which blocks your conversation with companions from being eavesdropped upon by other radio users. These radios have different ways of getting call alerts to be notified if a new message is on its way.

The radios of today are being equipped with a weather channel, which gives you the latest weather information. Little left to wonder, some highly efficient two way radios are endowed with features like barometer, thermometer, digital compass, AM/FM radio and GPS navigation unit. This handheld and easy-to-carry gadget is becoming much helpful in facilitating our lives to a great extent.

Do you know why two way business radios are such a craze nowadays? It is mainly because they are a much cheaper means of wireless connectivity and, at the same time, ideal for use in a lot of places. These radios even remain active in certain places where mobile phones prove to be ineffective. It will take a large space to mention all the places where these radios can be used.

So, here the name of few places is mentioned where two way radios can be effectively used. Construction site is one of the places where these radios are frequently used. Restaurants, Government Offices, and Hospitals are some of the other places where people can stay connected with each other with the help of two way radios. Theatre, Manufacturing areas, and Campus also witness large scale use of these radios.

Two way radios are randomly used in Military applications. In fact, the initial use of these radios was restricted to the police only. In course of time, the radios have got their access to the public life and caught up in popularity very fast. Otherwise known as walkie talkies, these radios are ideal for use in many outdoor activities as well.

From Hunting to Skiing, Driving to Biking: in all these outdoor activities two way radios are frequently used. During the time of Vacationing, at School, in Sports: these radios have their part to play everywhere. Thus, this easily portable, handheld device is contributing a lot to keep people connected in so many places and in so many ways.

However, two way radios have their limitations. They do not work outside a certain range. In this case, they are less advantageous than a mobile phone. But when you consider the cost, the radios certainly get an edge over the phones. You can get non-stop service from the radios just after buying them. Whereas, mobile phones cost you high amount initially and necessitates you to pay every time you use them. In this case, the radios appear to be a far better option.

Two way radios are available in various models and each model in endowed with a different set of features. With the increasing usage of the radios for communication, both in the corporate sphere and the family surroundings, it is imperative to keep a few things in mind in order to make communication more effective and to completely enjoy the advantages of all the features.

The main thing that has to be considered while buying two way radios for a single closed group of people to communicate with each other is that the radios should be of the same model and from the same manufacturer. The best example of this would be that of an office. When multiple two way radios are bought for employees of a particular office or even of a particular unit, it is presumed that most of the times they would need to communicate with each other. The need mostly arises if they are in the sales and marketing scenario and are constantly on the move. Their colleagues or even their manager may require contacting them often, and hence two way radios are the most cost effective means of communication, because calls placed through them are free of cost.

Similarly, in a family scenario, it is advisable to have the same model for the members of one family, because they might need to communicate with each other often. Parents who are working may require being in touch with their children, or if there is an aged or a sick person, then family members may feel the need to enquire about their well being.

If the two way radios are to be used within a specific group, then it is preferred that they be of the same model. This is because, to avail the full features of the radio, the other radio also should have the same provisions and features. Features like privacy codes, eavesdrop reducer and many others may not work properly if the other radio is of a different make.

Hence, just keep these simple guidelines in mind and enjoy your conversation with your group using two way radios.

Two way radios are now being manufactured in amazing models having numerous features. Earlier these radios were just crude models that were used for free communication within a particular range. One got to see these radios only in the hands of army men, police men or marketing personnels i.e., mostly in the hands of people constantly on the move. But owing to the introduction of exciting features and smart models, these radios are now used for communication among family members as well.

Despite being used by families as well, two way radios are still more popular for outdoor usage. The higher the price, the more the features. One of the exciting features in high end models that is useful for outdoor users is a key that locks your channel so that it does not change when a person moves around. Other features include a digital camera, an AM/FM radio tuner, digital compasses, alarms, thermometers and barometers and even stop watches.

Another exciting and innovative feature available in two way radios is the Auto Squelch that keeps the radio silent until a signal is received. It also has a last channel recall button that is similar to the redial button on a normal phone. Other useful features include an auto channel scan that scans all channels for signal, along with a backlit LCD that enables the user to see the display even in the dark. There is also a provision to attach more speakers and microphones.

For outdoor users, Two way radios now come with various accessories that not only enhance its look and makes it user friendly, but some also prevent wear and tear of the radio when it is exposed to harsh conditions. These include waterproof cases, charging units, headsets and shoulder and belt holsters.

All these features and accessories make two way radios the best communication gadgets for outdoor usage.

With each passing day, we are introduced to better models of two way radios, having more innovative features. Every new model introduced has a new feature accompanying it. All these innovative features have contributed to the increased usage and popularity of these radio instruments. People have started adopting it as commonly as a mobile phone.

The number of channels in two way radios differs depending upon the type of two way radios being used. The FRS (Family Radio Service) offers users 14 channels, while the GMRS (General Mobile Radio Service) gives users 23 channels. Hybrid radios (a combination of FRS and GMRS radios) offers users the facility of 15 channels or more. In fact, the number of channels offered by a radio is directly proportional to its price; the more the channels the higher he price.

Other unique features available in two way radios these days are:

Battery Type: The battery of two way radios is designed for durability and endurance. Portability is also another factor; hence all devices have an internal battery. For users who use the radio less, there are AA and AAA alkaline batteries, but people who use the radios often can go in for Nickel Metal Hydride or Nickel Cadmium Batteries that can be recharged.

Weather Channels: Many radios these days have weather channels that provide users the weather news and forecasts by the official meteorological department. This feature is ideal for people who have to travel a lot for work, both within the country and abroad.

VOX: This feature makes the push button in two way radios redundant. Earlier, in order to speak, users had to push a button. But the voice activated system, or the VOX starts broadcasting the moment the user speaks in the direction of the radio. This feature is extremely useful when the user is engaged in some other task like driving, as it provides a hands free facility.

The popularity and the increasing demand for two way radios has not only increased their visibility in the market, but has also encouraged engineers to add features that make it more user friendly. Today, these radios are available in smart and light weigh models and are equipped with a quite a number of additional features. The buyer has the advantage to pick up transmitters that have the best combination of features that are most suited to his requirements.

The unique features that are available in two way radios are:

Call Alerts: This feature allows user to choose their incoming call alert from a variety of tones and styles that are incorporated in the radio instrument itself. The tones may include a number of ringing melodies, and the user can choose from ringing styles like vibrating alert, vibrating and ringing, and only ringing, among many others.
Privacy Codes: This is an extremely unique feature of two way radios that enables users to use the option of privacy codes. Using this feature, the user can block out other unwanted communicators who have tuned in to the same channel and frequency as him. He can choose who he wants to talk to and have a quiet and peaceful conversation, by barring others who have tuned into the same channel. This feature allows the user to have a one to one conversation whenever he wants.
Eavesdrop Reducer: This feature is available in high priced two way radios. It scrambles transmission by using the voice inversion technology. It is basically used for people who use FRS (Family Radio Service) radios and are tuned into the same channel and frequency. This system prevents other people, using FRS, from eavesdropping on your conversations when you are speaking to your partners. Together with privacy codes, the eavesdrop reducer provides complete privacy to conversations on two way radios.

Two way radios have many more exciting and innovative features that have not only made them more user friendly, but has also enhanced the quality of conversations that people can have using this device.
