Wow. The new earpiece is awesome. I mean it’s just so stunning so sophisticated. I pity people who grew up without the radio accessory.

Whenever you hear about a two way radio the first thing that comes to mind is a device that has unattractive looks and a fuzzy sound.
These factors would never let you believe that this device is still being used in the 21st century. This doubt gains more strength when you see well-polished and glamorously designed smartphones and tablets for communication. However, the reality can‚ be further from the truth. The importance of two way radios in the modern century can‚Ŵt be explained in just a few words. There are many developments in this device which makes it very important.
Versatility
The number of places where you can use two way radios are virtually limitless. They are easy to use and have many features which makes them useful for all types of uses. That’s why you would see them being used at nightclubs, construction sites, battle zones and industrial units. This versatility is only provided by a two way radio to its users. This makes them a great asset for many people working in tough conditions.
Durability
The modern two way radios are tailored specifically for use by people who are involved in dangerous work or have an active lifestyle. The two way radio sets you find today are shock-proof, water-proof and rubberised to provide a longer working life. These features make them suitable for use in tough conditions like under water, in air or on mountains. You don’t have to worry about them breaking after being dropped or even stop working due to any damage. This durability is not provided by any other communication device except two way radios.
Voice Activation Capability
There are many new technological upgrades that have been added to the latest two way radios which make them a truly advanced communication device. The best example for this is voice activation capability or VOX. Millions were spent by Apple on the development of their technology for the iPhone. Although, VOX doesn’t have all the capabilities of something like a Siri, it surely can do most of the basic things. Due to the use of VOX technology you get the ability to operate your two way radio by giving voice commands. This is very helpful for communication when your hands are full and you want to use different features of your two way radio.
Throat Mic
VOX is not the only technological advancement which makes two way radios an important communication device of the 21st century. There is another technological option called a throat mic. A small mic is clipped around the neck of the user and is connected to the two way radio. This setup helps in the reduction of the distortion caused by background noise by up to 90%. That’s because sound is directly picked up from the user’s voice box. This might seem a little scary but it works efficiently in achieving clear communication between the users of two way radios.

You could easily realise the importance of the two way radio technology in the 21st century by reading this article. There are many more tricks that two way radios from two way radio shop are able to perform, which makes them an impressive gadget of the 21st century.

Walkie Talkies – An Overview

Posted on November 14, 1990 Updated on September 30, 2014

This article is posted by the faithful permission of radio earpiece.co.uk, that is the original blog. please get permission from that site before reposting this piece.

Walkie talkies are unique in that the half-duplex channel they operate on will only allow one radio to transmit at any time, though there are no limits to the amount that can listen.
Rather than have an earpiece similar to a telephone, they have a built in speaker so the unit does not have to be held to the ear. They are used to connect to both other handheld units and to radio stations which are in a fixed location. The typical shape is of a large telephone handset, with a fixed antenna poking out of the top of the unit.

History
The fist radio audio transmitter and receiver that was coined the ‘walkie talkie’ was created by Motorola. The group involved created the Motorola SCR-300 using frequency modulation. This first revision was actually backpack mounted. Not long afterward, during World War 2, Motorola produced the ‘Handie Talkie’ which rather confusingly is what we would now recognise as a ‘Walkie Talkie’.

It had massively reduced performance, but was the first completely self contained handheld device.
Nowadays
They are widely used nowadays in both consumer and commercial environments, for example outdoor recreations, business use, military and public safety. As a result of this the prices and quality of the units vary greatly, from kids walkie talkies to rugged digital units for heavy industry use.

As technology has improved, and reduce in size, so have the housings. Normally, you will find the commercial walkie talkies are tougher, in protective cases and limited to a select few frequencies. Consumer versions on the other hand tend to be smaller, more lightweight and capable of scanning across far more channels within the band.

Kids walkie talkies are generally low power units, and as a result are exempt from licence requirements. Though they often look the same as fully featured versions, they are normally relatively low-tech in comparison.
