What types of radios are there

They have a range from one to 15 miles, but they are very line-of-sight sensitive, so conversations can cut in and out if one or more radios are mobile. Any power modifications are subject to steep fines. It comes with an extra-long microphone cord and the ability to connect to external speakers for use as a Public Address system. This Uniden operates at the maximum four watts and features a built-in automatic noise limiter and auto-squelch to eliminate background chatter and improve communication.

Amazon reviewers praised how it was easy to install, and some noted its durability over years of use.

They did, however, suggest investing in an antenna, as it seriously increased the range and sound quality. The HHRT50 is ideal for travel, as it comes with a mobile antenna you can secure to any vehicle to boost the range. It also features a sound tracker system, which eliminates 90 percent of background noise. It can reach up to 40 channels and even allows you to simultaneously monitor two channels at a time so you can keep an ear out for relevant alerts. The 10 NOAA weather channels also help keep you updated with the latest conditions in case of an emergency.

According to Ralph Hollis, engineering project manager at Midland , GMRS is "fast becoming the most popular class of portable two-way radios. There is no test required, and the license covers an entire family for a period of ten years. These stylish red walkie-talkies from Cobra offer up to a mile range and ten NOAA weather channels. The ten different call tones can help you differentiate between individual callers in your party, and a roger beep lets you know when someone is done speaking.

Built for the wilderness, the ACXT conserves energy by turning off after ten seconds without use and even has an LED flashlight to help you find your way in the dark.

Other features include privacy codes, waterproofing, and NOAA weather alerts. And the whisper mode can be especially handy; it allows you to speak quietly and still be heard. The GXTVP4 is great for camping or hiking, not only because the radios are durable and have a long range but their size means they can be easily thrown in a pocket or backpack.

Battery life is great, too. Once you feel the freedom of communicating with a two-way radio, you may gravitate toward wanting to talk to people at a much farther distance than CBs and GMRS radios can provide.

Popular culture tends to stereotype ham-radio operators as tinkerer-geeks from a bygone era—and indeed, many ham operators enjoy fiddling with their gear and learning about how to operate their radios almost as much as using them. But the technology still fills an important role. When phone lines and cellular networks go down, for instance, ham operators always step up to the plate to assist in emergency situations.

Plus, a ham radio can interface with a computer or tablet to send data, texts, images, or Morse code, which makes the class even more valuable and versatile than other types of two-way radios that are only capable of transmitting audio.

The FCC requires that ham-radio users be licensed. There are three classes of licenses that all require a written test of 35 to 50 questions covering radio theory, regulations, and operating practices.

Mobile radios are used in vehicles and are permanently mounted. They can have up to watts of power, need special licensing and setup, and you can expect more range with these types of radios. Base stations are placed on a desk or counter. They pug into a standard electrical wall socket, and use a antenna usually located on the highest point of the building where they are located. They also can have up to watts of power, need special licensing and setup, and you can expect more range with these types of radios.

A number of different manufacturers support this trunking technology. Tetra : As the world becomes more digital, a number of digital radio technologies have emerged. One of these is Tetra, developed in Europe in the late eighties. P Another major open standard for digital radio technology is APCO Project 25 or P25 for short which was developed specifically for public safety agencies in the United States. P25 Phase 1 differs from Tetra by being an FDMA technology and also supporting conventional, trunked, and simulcast operation or a combination of all three of these.

It can be employed by non-public safety users as well. P25 actually comes in two phases. Phase 1 is an FDMA technology operating in the Phase 2 is a more recent development and is only available in trunked. It is also TDMA and offers two time slots in a single DMR is increasingly used by businesses such as mining, utilities and transport throughout the world.
