Radio Wireless
Radios are one of the means of communication that are used widely and popularly. One of the best things about a radio is that it can be easily carried from one place to another. Radios are of various types. A broadcast radio is the one that only receives content and cannot transmit it back. A two way radio is the one which can receive as well as send content or signals. It is the most popular type of radio used these days.
A two way radio is available in many different configurations. A few of the popular configurations include the hand held portable configuration, mobile configuration and the stationary base configuration. The hand held portable configuration can be carried from one place to another and are easy to use. It is also called a walkie talkie. The mobile configuration is the one in which signals can be received and transmitted at the same time. The mobile configuration is very easy to use and can be conveniently carried from one place to another. The stationary base configuration is the one which cannot be carried around but is very easy and convenient to use.
The use of this type of a radio can be traced back to the use of transmitters and receivers that were used to exchange messages wirelessly. The first two way radio was developed in Australia in the year 1923. The Victorian Police were the first ones to use this type of a radio for wireless communication in cars. This made it very convenient to communicate. Later with the development in radio technology, most vehicles were installed with two way communication radios. These transceivers were very popularly used in World War II.
A two way radio operates at different frequencies. In addition, the frequency for each country is different. There are several factors that determine the frequencies at which two way radios operate. These include licensing conditions set by the government in each county, the licensing regulations, availability of radio frequencies, the type of area in which radio signals have to travel, interference and noise levels that are present during transmission and reception of signals etc. The type of area affects the frequencies at which radios operate. Radio signals cannot easily travel across certain areas like forests and rural areas. So whenever, a frequency has to be set for these types of radios, it has to be ensured that the area is taken into consideration. Frequencies also have to follow the regulations that have been set so that they do not interfere with other frequencies.
Each frequency is known by a channel number mainly because it is easier to remember a channel number than remembering a frequency in hertz. Most radio service providers use channel numbers instead of frequencies and even the users find it more convenient. Also all radio signals have to follow a communication protocol. This is important so that radio stations can cooperate with each other for providing radio signals. This also ensures that one radio station does not interfere with another station.

Where can I buy a wireless DAB radio with a head phone?
When I don’t sleep well I listen to the radio lying down. I want a radio that has an ear piece but no wire. Bit like a handsfree mobile in one ear but it must be DAB so I can listen to Radio 5.
There are several in the Argos catalogue.
