Citizens Band Radio – 11M.
CB Radio is a system of short-distance radio communications between individuals on a selection of 80 channels within the 27-Mhz Band. In the United Kingdom, CB radio was first legally introduced in 1981. On 27th June 2014 changes were made to allow the use of AM & SSB modes on CB in the UK legally for the first time.
PMR 446 Mobile Radio
PMR 446 has become more popular over recent years, the small form factor of both radio and antennas for 446MHz makes it much easier to use. Sometimes known as Walkie Talkies, PMR446 is popular amongst many groups of users, from the enthusiast, to walkers, to small businesses many people use 446.
Free Radio network is available to download on Microsoft windows devices. Simply, download the software, complete the registration, and then browse through the many Servers hosted across the world. I can be found occasionally on the following Servers:

Users are able to Host Internet RF gateways, by using what is known as an “Interface”. I have a variety of interfaces made for different radios by Alun – M0AQC and these work Fantastically.
At Home I have a few Baofeng BF-888s UHF radios which are programmed to PMR446 (500mw ERP). I have recently hooked one of these up to FRN, to create the “Chepstow PMR Internet Gateway” It is accessible on PMR CH6 (446.06875) and requires tonecode 20 (CTCSS 131.8Hz) to access the gateway.
To check if you can access the gateway you can simply key up and Say the Following “This is YOUR NAME HERE Checking for access to the gateway” within a second or two from de-keying your radio you will hear the Gateway return a 3 tone bleep meaning you have accessed the gateway.
