UK walkie talkie frequency FAQ (2023)

Make sure that Very High Frequency (VHF) signals for devices are between 30 MHz and 300 MHz and Ultra High Frequency (UHF) signals are between 300 MHz and 3000 MHz. Depending on the power (measured in watts), the Walkie-talkie transmissions can range from a few hundred meters to a few kilometers or more, depending on whether your model is being used.Digitalor analog transmission, the location of the device, and the type of frequency you are using (VHF or UHF).Walkie-talkies, or radio devices, transmit and receive information via radio signals at various possible frequencies using digital or analog technology.

license options

There are eight license-free UHF walkie-talkie channels in the UK, as well as corporate channels that require an OFCOM license. these channels arewith licencebecause they protect the communications of emergency services, including police, emergency services, railways, military, air traffic control and naval services, and ensure that they remain free from interference from other users. There are special models of walkie-talkies aimed at companies that operate on licensed UHF (400 – 470 MHz) and VHF (136 – 174 MHz) channels that require a license.


Walkie-talkie transmissions can range from a few hundred meters to a few kilometers or more, depending on their power (measured in watts), whether your model uses digital or analog transmission, the location of the device, and the type of frequency it uses ( VHF or UHF). The range of your walkie-talkie depends on where you use it: a built-up area will reduce the transmission range of your walkie-talkie, while a flat, open area will allow for wider transmission. For longer range transmissions, VHF signals between 136 and 174 MHz are recommended, as they cover longer distances better with the same power output. That is why VHF is used in marine radio. However, UHF signals (400 – 470 MHz) are more suitable for urban areas and offer better penetration with the same performance. If you're looking for a general walkie-talkie frequency, UHF is probably your best bet.

To further complicate matters, a walkie-talkie is traditionally a transceiver set up to use analog FM signals. With the growth of digital technology, a number ofTwo Way Digital Radiosare available and use private digital services without a licensecell phone(dPMR446) and Digital Mobile Radio (DMR) channels that broadcast on 446.1 – 446.2 MHz. These products may have better range and sound quality, but are much more expensive. Digital walkie-talkies allow conversations between multiple users, as well as encrypted one-to-one communications, text messages, and security calls, and are designed to accept traditional analog signals as well. However, there may be compatibility issues for different types of digital walkie-talkies.

walkie-talkies without a license

License-free walkie-talkies are specifically designed to be used in a way that does not interfere with priority signals and can be used by anyone in the UK without a license. They are cheaper and less powerful than walkie-talkies designed for licensed frequencies, but can meet many everyday needs. Often referred to as "PMR446" radios due to their frequencies, they can only have a power output of 0.5 watts, which means their range is less than that of more powerful licensed commercial walkie-talkies, which have a power rated at 4 to 5. watts (or up to 25 watts for car radios and "base stations"). because they are strongerlicensed radioshave a longer range and better signal penetration in buildings. License-free walkie-talkies may also experience more interference when used in an area with multiple users on the same channels, but this can be overcome by using a model that supports "codes" as described below, or by changing the channel switching . Because they are cheaper, they are easier to change than more powerful models.

tones and codes

Walkie-talkies can also be configured to use several possible "identification tones" on each channel. Set your radios to a specific channel and tone and only listen to messages from other radios set to the same combination. Two types of codes are available: Continuous Tone Coded Squelch System (CTCSS) or Digital Coded Squelch System (DCS). However, these codes are not suitable for emergency services that need access to a specific channel in a specific location at a specific time.

A system of FRS and GMRS channels is used in the US, roughly equivalent to PMR channels, but devices using them are not licensed in the UK. PMR frequencies have been 'harmonized' for use across Europe, but you need to check that they are approved in a specific country where you intend to use them. For example, in the United States, PMR frequencies are commonly used for radio amateurs.

UK walkie-talkie frequencies and licensing options

The Simple UK Light Walkie-Talkie license is available from OFCOM for a standard five-year fee of around £75 per organization and allows transmission on a specified frequency band to all users who hold the licence. It can be used anywhere in the UK. Alternatively, there are several custom license options that can be created for access to a specific frequency or for exclusive use of a frequency by your organization within a specific limited area. The price of this license varies depending on the radio frequency needs in the area and the frequency cannot be used outside of that area. Finally, a license from a commercial radio provider can be used if you rent their walkie-talkies from a specific retailer or borrow a unit to try it out.


The International Telecommunication Union is a United Nations organization dealing with communications technology. The ITU sets standards that the industry adheres to. Radio wave frequency classifies different wavelengths into different bands like UHF or VHF.

ultra high frequency

Ultra high frequency is in the frequency range of radio waves between 300 megahertz (MHz) and 3 gigahertz (GHz). This frequency is also known as the decimeter band because the wavelengths themselves range from one tenth of a meter to 1 meter. Decimeter means only one tenth of a meter. UHF radio waves work primarily through line of sight and are blocked by buildings and hills.


Lower frequencies than UHF, the very high frequency spectrum of radio waves is defined by the ITC as between 30 megahertz and 300 megahertz. These are also subject to line of sight as they are blocked by buildings and hills. However, they can travel about 100 miles due to the refraction of light. VHF is commonly used by digital audio broadcasting (DAB) and FM radio stations. This band is also used for two-way radio systems, from emergencies to maritime communications.


Family radio service is a personal radio device with frequency transmitters and radio wave receivers in the devices that are set for a shorter range. FRS uses channel frequencies between 462 MHz and 467 MHz, which is in the UHF range. At short intervals, predictable FRS can be used instead of free radio channels.


The more traditional system than the two-way radio system most people are familiar with, the Professionalcell phoneis the person-to-person voice communication used in walkie-talkies. To be used when 2 people are in the same place but need to communicate when they are not next to each other. There may be a matrix system where more than 2 devices are using the same network but only one can talk at the same time. Usually, you press a button to activate the microphone.


The general service mobile radio is another form of professional mobile radio. Designed for two-way communication over short distances. GMRS is an American standard for two-way communication and cannot communicate with British walkie-talkies. In fact, the frequencies used for GMRS would interfere with some emergency services.


FM is a form of radio transmission and stands for frequency modulation. FM radio offers higher audio fidelity over the airwaves. FM radio encodes the audio data and sends it to the receivers, the receivers decode the information and play the sounds through a speaker.


BritainCB-FunkFrequencies span 40 channels within the 27 MHz band. Citizens Band Radio was launched legally in 1981, but was previously used illegally. CB has been deregulated by Ofcom which means it can now be license free. British CB radio frequencies are mainly used in farming communities and in Land Rover vehicles.


Due to the nature of radio communications, it is important to get your message across as clearly as possible. To avoid confusion, a universal code language for walkie-talkie use has been adopted. Motorola's corporate radios are used for military purposes, but are also being adopted by the private sector. They're great, but depending on the interference, they can have static noise.

These are some of the most common codes:


The most familiar numbered code we see in the movies, 10-4 simply means the message was received.


If the message is dark or hard to hear, 10-9 would be a request to repeat the message.


Probably mentioned in the question "what's your 20" or in the "got your 20" statement; 10-20 is the same as saying my location is XYZ. 20 simply means location.


A faster, easier way to say you got the message. At the time when Morse code was the communication used, the letter R stood for the received word, which became the word Roger.

copy of

It also means that the message has been received.


To indicate that you have finished speaking for the moment. Out Used after the word over to indicate that you have finished your current transmission and will no longer respond.
