How Was the Walkie-talkie Invented

Although two-way telegraphy and the two-way radio has been invented years earlier, it was only during the years from 1934 to 1941 when the first hand-held two-way transceiver or the walkie-talkie was first developed. Two persons and an engineering team were credited for inventing the device, and they are radio engineer Alfred J. Gross, Canadian […]

What Walkie-talkies Do the Police Use

In the interest of public safety and security, the police have been the first to use walkie-talkies in the conduct of their jobs, especially for patrolling and emergency purposes. It was in 1923 when Senior Constable Frederick William Downie of the Victorian Police in Australia developed the first mobile two-way radio, which paved the way […]

What Frequencies Do Walkie-Talkies Use

Two-way communications become possible in walkie-talkies because signals are transmitted and received via a specific radio frequency or channel. While there is a wide bandwidth of radio frequencies that communication devices are allowed to transmit and receive signals, private walkie-talkie users have limited channels or radio frequencies to operate in since most of the other […]

What Does VOX Mean on a Walkie-Talkie?

Modern walkie-talkies feature Voice Operated Exchange or VOX in place of the standard and traditional ‘Talk’ button. Known as a voice-operated switch, VOX is an electronic sound sensor that turns on the transmitter of the walkie-talkie when the user speaks loud enough to transmit voice data. Oppositely, the VOX automatically shuts off the transmitter when […]

How to Use Walkie-Talkie Radio

Using a two-way walkie-talkie radio is very simple. Each hand-held device comes with a built-in speaker and microphone as well as other electronic components that enable it to both transmit and receive signals or voice data at different radio frequencies. Certain electronic components inside the walkie-talkie convert audio or voice data received by the microphone […]

How Do Two-Way Radios Work

Also called transceivers in the technical parlance, two-way radios are radios that are capable of both receiving and transmitting signals and content, usually in the form of voice data. Communications become possible between two persons each operating a two-way radio provided they meet on the same radio frequency called a channel, where each of them […]
