Frequency spectra are somewhat arbitrary groups selected to some extent for the benefit of regulators, but VHF is 136-174 MHz and immediately above it is UHF at 400 to 512 MHz. This makes them better able to penetrate structure, so people sometimes think of UHF as ‘more powerful.’

The T800 Extreme is one of the newer range of walkie talkies Motorola are pitching as the future. The sleek, lightweight design is in line with that modern outlook. The T8xx series two-way radio work just like every other radio by sending information using radio frequencies to keep you connected while off-grid. The secret to the T8xx series is once your smartphone is connected to your radio over Bluetooth, the Motorola Talkabout smartphone app enables communication options beyond push-to-talk. The Motorola TALKABOUT app uses the T8xx series as modem to send messages, locations and more over the radio frequencies to your fellow T8xx series users. With enhanced communication and more information you enjoy unrivaled connectivity for peace of mind off the cellular grid. Frequencies on the electromagnetic spectrum are divided into broad categories (visible light is one of these) and the subcategories are known as channels. For convenience, these are named with simple numbers within GMRS/FRS For example, Channel 1 is 462.5625 MHz. All 30 GMRS channels, including the 8 repeater channels, are supported in receive and transmit modes, and dual PTT buttons make it easy to take advantage of the semi-duplex function. This monitors two channels at once, giving priority to the one with an active call. With these two, you have over 2000 channel combinations to choose from. Add the quiet talk (QT) mode to the mix and experience the quiet and easy pleasure of getting an unoccupied channel for private communication.More buttons can be found on the front of the 2-way portable radio. The illustrated user’s guide listed them as the call tone, monitor, scan, menu, and mode buttons. The Motorola T82 is free to use, resistant and practical. It’s ideal for professionals or for leisure activity enthusiasts. It can be used outdoors, indoors, in environments such as shops, sports centres, water parks and more! The range that walkie talkies cover depends on your line of sight. In theory, if two radios are about the height of a human, then the range will be around six miles (10km); any further and the curvature of the Earth gets in the way. Valleys and mountains can disrupt that dramatically, though, as can a repeating station. (If you need a greater range, see our roundup of the best satellite phones). The T460 is a compact, rugged, lightweight radio you could use for many outdoor activities such as camping, hiking, skiing fishing, etc. Even if you run out of power and can’t charge it immediately, you also have the option of using disposable AA batteries. The smart move is to get as many disposable batteries as possible so you won’t be caught off-guard power-wise.

Communicating – The PTT button is conveniently located on the side making it easy to exchange messages. The audio reception was clear even in windy situations. I didn’t have to repeat myself most of the time.

Battery – When you have a device with a dual power source, you are not likely to ever run out of power with good planning. The built-in flashlight helped to illuminate the path ahead of me. In that situation though, I wished the beam was super bright. It barely showed the way ahead up to a few feet only. The casing is made of durable plastic material that is made to withstand rough handling and weather. All the ports (for connecting earpiece or charging cables) are sealed with rubber flaps to prevent water, dust, snow, etc, from getting into it.
