Description

A hand crank emergency radio is a portable AM/FM receiver with a small dynamo inside: turning the fold-out handle charges its built-in rechargeable battery, so the radio never depends on mains power or fresh batteries. It is made for disasters, when the electricity is off for days and mobile towers are down but radio stations keep broadcasting weather signals and relief information.

Why is it useful in Bangladesh?

• Cyclones and storm surges — danger signal numbers and evacuation notices are broadcast by radio and reach the coast even when the network fails.
• Floods — in char and haor areas power can be out for a long time.
• Earthquake preparedness — a radio is a standard item in a family emergency bag.
• Fishing boats and trawlers — weather bulletins at sea.

How does the crank work?

Unfold the handle on the side and turn it steadily, about two turns a second. A minute or so of cranking typically gives several minutes of listening at moderate volume; the exact time depends on the volume and the condition of the battery. Because the energy goes into a rechargeable battery, you can crank in advance and listen later.

Features of this radio

• AM and FM bands with a large analogue tuning dial
• Telescopic aerial for FM; internal aerial for AM
• Built-in speaker and volume knob
• Fold-out dynamo crank and charging indicator light
• Carry handle on top
• Black, sturdy plastic cabinet

Many radios of this type can also be charged from an external power adapter, and some can pass crank power to a phone through a charging socket — enough for a short emergency call rather than a full charge.

How should you look after it?

A rechargeable battery that sits empty for years loses capacity. Crank the radio, or charge it, for a few minutes every two to three months, and store it somewhere dry. Keep it with your torch, whistle and first aid kit so that the whole emergency kit can be picked up at once.

Applications

• Family cyclone and flood emergency kits
• Coastal, char and haor households
• Earthquake preparedness bags
• Fishing boats and trawlers
• Cyclone shelters, NGOs and relief teams
• Camping and remote site work

Recommended usage

Store the radio with your emergency kit and top up its battery with the crank or charger every two to three months. In an emergency, extend the aerial fully for FM and turn the whole radio to improve AM reception. Crank steadily rather than fast.

Safety instructions

Turn the crank at a steady pace — forcing it very fast can damage the gears. Keep the radio dry and away from salt spray; wipe it down after use on a boat. Do not extend the aerial near overhead power lines or use it outdoors during lightning.
