What Is A 2-Way Radio?
A two-way radio, also known as a walkie talkie, is a hand-held radio that can transmit and receive radio signals, unlike a purely broadcast receiver that only receives data. It’s an infrared transceiver, a hand-held transmitter and receiver unit in one piece, usually used for two-way person-to-person conversation with other wireless users with similar handsets. In the past, these devices were quite large and bulky, making them not portable or easy to carry. Today, the size of most two-way radios has decreased significantly, making them very portable and easy to carry. Some two-way radios have a battery installed internally for additional power, but most of them are rechargeable. Most models have a standard antenna feed, allowing for maximum coverage in a given area.
The maximum range on a typical two-way handheld radio will vary depending on the model. The number of channels you can operate on varies according to the manufacturer and your radio’s wattage output, but you should be able to get about thirty channels of operation, though most operate in the lower limit of this frequency. The range will be less if you don’t use a lot of Frequencies (for instance, if you rarely travel), but if you plan to travel a lot, you will probably want to consider spending the extra money to purchase a more powerful model. However, keep in mind that even the most powerful two-ways transmit at a much higher wattage than many other handheld devices, and thus are not recommended for general use.
Some 2-way radios can work on lower wattage output levels, but these devices are rare and most manufacturers do not produce them. These radios often have limited range, because the signal is often emitted from a single transmitter, rather than being combined with others. When a single transmitter is used, the power output of the radio is limited by the distance between the transmitter and the receiving device. However, if multiple transmitters are used, each one will emit its own wattage output, giving the most range possible. Because these devices are most often used on ships and in large fields, they are typically not recommended for personal use.
