Best Off-Grid Communication & Signalling
When mobile signal drops or a group needs to split up and stay in contact, phones aren't enough — a dedicated way to talk and a backup way to be found matter just as much as anything else in a kit.
We've picked a pair of long-range walkie-talkies for staying in contact across a campsite, hillside or during a power outage, a pealess whistle that carries much further than shouting, and a glow stick for marking your position after dark without needing a working battery.
Item entry
Two-Way Radios
When phone networks are down or you're out of signal, two-way radios keep your group in contact. Essential for coordinating a family, a hiking party, or neighbours during an outage.
Features to look for
Genuine usable range
Advertised ranges assume perfect line-of-sight. In towns and woodland real range is much shorter, so favour proven models and test them where you'll actually use them.
Rechargeable with AA backup
Rechargeable packs are convenient day to day, but models that also accept AA batteries let you keep going when there's no power to recharge.
Licence-free PMR446 channels
In the UK, PMR446 radios need no licence and are legal to use out of the box. Check the set is PMR446 for hassle-free, legal operation.
Common mistakes
Trusting the box's range claim
A '10km range' radio may manage a few hundred metres in a built-up area. Test realistic range before you rely on it for safety.
Not agreeing a channel
In an emergency there's no time to fumble settings. Agree a channel and sub-code in advance and write it inside the case.

Motorola Talkabout T82 Extreme PMR446 Two-Way Radios
A licence-free PMR446 radio pair from Motorola, built for the outdoors with a rugged, splash-resistant body and a bundled hard case. Handy for keeping a group in contact on a hike or coordinating at home when the mobile network is down. Range is line-of-sight so treat the box figures as best-case, but for short-range family or team comms it does the job.
- Licence-free PMR446 — no paperwork, works straight out of the box
- Rugged splash-resistant build suited to hills and bad weather
- Rechargeable batteries plus AA backup for flexibility off-grid
ROCAM Wind-Up Emergency Radio
A hand-crank FM/AM radio built for the moment the power and the phone signal both go down and you need to hear official advice. Winding it charges the internal battery, so you're never reliant on finding fresh cells, and many units in this class add a torch and a USB port for topping up a phone in an emergency. Keep it in the grab bag or the cupboard under the stairs and give it a wind every few months.
- Hand-crank charging means it works with no mains or batteries
- FM/AM tuning to pick up local emergency broadcasts
- Compact enough to live in a grab bag or kitchen drawer

- IP67 waterproof rating handles rain and accidental submersion
- Four handsets cover a family or small team from one purchase
Esky Hand-Crank & Solar Emergency Radio
A wind-up AM/FM emergency radio that also charges from solar, USB or its 2000mAh internal battery, so you can keep hearing local broadcasts during a prolonged power cut. It doubles as a small torch and a top-up charger for a phone in a pinch. Crank output is modest, so treat the hand-crank as a backup to the built-in battery rather than the main power source.
- Four ways to power it: hand crank, solar, USB charge and internal battery
- AM/FM reception for local emergency and weather bulletins
- Built-in LED torch and USB output for an emergency phone top-up
