The type of two way radios often marketed as “walkie talkies” tend to be the licence free variety. These radios operate on one of the pre-programmed frequencies in the UK within the band 446.0 to 446.1 MHz. If this is the sort of product you're looking for, we sell a good range of licence free radios by Motorola, Kenwood, HYT and Hytera.
Although there are many good reasons for choosing a licence free radio, they do have lower power, a shorter range and can suffer interference from other users on the same channel.
