PMR446 walkie-talkies

What is a PMR446?

The designation PMR446 stands for Personal Mobile Radio, 446 MHz, and is a very accessible and license-free solution for two-way radio communication within the European Union. The 446MHz frequency band is specifically exempted for the use of walkie talkies, portable transceivers and two-way radios, which means that you do not need a license to use these devices. Although PMR446 two-way radios have a shorter range than licensed two-way radios, they still offer reliable performance for many everyday applications.

What are the differences between an analogue and digital PMR walkie-talkie?

• Analogue PMR446: The analogue PMR446 service is available throughout Europe, allowing users with analogue walkie talkies to communicate freely without a licence. This makes it an excellent choice for simple and direct communication.
• Digital PMR446: Digital PMR446 radios offer additional features such as data transmission. However, regulations for digital signals vary from country to country. This means that a digital PMR446 radio purchased in the Netherlands may not be usable in all European countries without restrictions.

Range and power

The effective range of PMR446 walkie talkies varies depending on the environment, usually between 1 and 5 kilometers. In urban areas with many obstacles the range can be shorter, while in open areas it can be longer. The maximum transmit power is limited to 500 milliwatts (0.5 watts), which helps to minimize interference and keep the devices license-free.

Key Features of the PMR446

• Frequency and Bandwidth: PMR446 operates in the UHF band, between 446.0 and 446.2 MHz. Analog devices use a channel separation of 12.5 kHz, which allows for eight channels. Digital devices have a channel separation of 6.25 kHz, which allows for sixteen channels. Analog uses frequency modulation (FM), while digital devices typically use 4-level Frequency Shift Keying (4FSK) modulation.
• Battery and Power: PMR446 walkie talkies typically use AA or AAA batteries or rechargeable lithium-ion batteries. Battery life varies depending on usage, but can last from a few hours to a full day. Many PMR446 units come with rechargeable batteries and a charging station, making it easy to charge the units between uses.
