There are two basic formats of Digital two-way radios and the two are incompatible with each other: FDMA (often referred to as dPMR) uses 6.25kHz wide radio channel; therefore half Ofcom license fee. TDMA (sometimes referred to as DMR) uses 12.5kHz wide channel for two timeslots. There is no discernible difference in performance between either technology, ALL use the same speech vocoder (they all sound the exactly the same!). Digital speech quality is not as good an Analogue system, but the usable range is much greater and digital speech processing means it is excellent for distinguishing human speech in noisy environments.
Most 'digital' radios are capable of operating in Analogue mode & mixed modes.

PMR 446 is a handportable short range voice only communication system, which provides a basic radio two way radio service for both business and non-business users. It is for providing communication over short distances. Only speech transmissions can be made. The PMR 446 service is licence exempt; users do not require a licence to use PMR 446 radios, provided the equipment complies with ETS 300 296. I.e. the radio equipment must be handportable, have an integral antenna, and have a maximum ERP (transmitted power) of 500 mW. There are eight 12.5 kHz simplex frequencies which can be used anywhere in the United Kingdom. The frequencies have been harmonised (but not necessarily authorised) for use across Europe. Before using PMR 446 radios outside the United Kingdom, users should check that the relevant administration, details of the progress made by CEPT member countries in implementing PMR 446 can be obtained from the European Radiocommunications Office (ERO). Users who fail to do this and use their radios overseas, may break the laws of the country concerned, run the risk of prosecution and the confiscation of equipment. PMR446 frequencies are all shared and users may, under local heavy use conditions, experience interference and channel sharing problems. This may be reduced by changing frequency and/or CTCSS tone and/or DCS code. As a licence exempt service, PMR 446 is unprotected and Ofcom will not become involved in interference or channel sharing disputes between users. PMR 446 radio equipment must use only the dedicated frequencies. Radio equipment which can operate on any other frequency must not be used for the PMR 446 service. - Ofcom (RA357, Nov 1999).

"PMR 446 is not suitable for safety of life use or for users who need to have guaranteed access to frequencies at particular locations and times."

From a pair of simple back to back two way radios for a single day, to a hundred plus multi-channel two way radios for months; whatever your requirement.

We only hire professional grade Two-way radio equipment; Handhelds (Walkie Talkies), Vehicle mounted radios, and Base Station/Repeaters to business & events across the UK. All our radio equipment is fully Ofcom approved & licensed (no extra charges!), is full checked prior to every hire and arrives ready to use. All our radios include a rapid 1-2 hour charging, clips, antenna, battery and Ofcom Licence; a full range of accessories including: Headsets, Speaker/Microphones, Earpieces, and Cases are available.

If you require the two way radio equipment to be programmed to your existing frequency this can often be carried out fairly simply. But we must have a copy of your up to date Ofcom licence.
