Whilst many of my visitors are interested in some of my own articles, here is one i discovered while surfing around blogger.com that is much better written than I might ever hope to achieve. Maybe in the future I will get to their rank, you never know.
A 2 way radio differs from a broadcast radio in the sense that it can receive as well as send messages and can be used for communication between two people. These types of radios are available in several different configurations. These include the hand held radios, mobile radios and stationary base radios. These radios can either operate in a full duplex mode or a half duplex mode. In the full duplex mode, these radios can be used for both sending and receiving data at the same time over different channels.
In the half duplex mode, these radios can be used for either sending or receiving data over a single channel. There are various things that one needs to know about the 2 way radios . These radios are very compact, are light weight and are available at a very affordable cost. These radios are available in different styles and are used for a large number of applications.
These radios generally have a push to talk button that make it very convenient to use and easy to handle. These radios are available with either rechargeable batteries or replaceable batteries. These batteries can either be made of nickel and cadmium or of lithium ion.
The 2 way radios operate in different ranges. The range specifies the distance that can be covered by these radios for communication. These radios can operate over short ranges or long ranges. This depends upon various factors like the frequency, the type of terrain etc.
Most of these types of radios operate in line of sight frequencies. This means that they cannot work well in hilly areas and in places where there are obstructions. These radios come with a large number of features. These radios are even made compatible with computers so that they can be used for sending data from one computer to another computer.
Another thing that users must know about 2 way radios is that these can even be used for hands free communication as these are available with handsets. These radios may or may not require licenses for their use. When these radios are used for personal purposes, the need of licenses does not arise.
If these radios are used for the purpose of business or in organizations, then the users need to obtain licenses for their use.
The 2 way radios operate on different channels. Since these channels are open, anyone can listen to the communication or intercept the messages being sent. To prevent this, these radios come with a privacy code. Also most of these radios are provided with scanning functions so that the channels can be automatically scanned for and manual setting of channels is not required.
These radios can be purchased from stores that deal in electric gadgets or can be bought online. The internet is the best place to buy these radios as a user can compare the various types of radios available and then choose the best one. This ensures that the user gets the best deal and does not end up purchasing a radio that does not satisfy the requirements of a user.
