So, you may be interested in AR? How do you go about it? What do you
Firstly, what do you want to do? Talk to people? Listen to people talking? Listen to far-off broadcast stations? Build your own receivers and transmitters? That's a lot of questions on the start of what should be an information page! Perhaps it serves to highlight that AR can be (nearly) all things to everyone.
To start with - listening requires no licensing of any kind, you just have to build or buy a receiver, and start using it! By law you are only allowed to listen to a few types of radio signals, and whilst ownership of a receiver (such as a scanner) which can pick-up other signals is not illegal in itself, using it to listen to, say, mobile telephone calls IS illegal.
You are allowed to listen to:-
Amateur Radio ( 'Hams' )
Broadcast stations (BBC, World Service, ILR, etc)
Standard Frequency Services
What is Frequency?
You are NOT allowed to listen to:-
The Emergency services (Fire, Police, Ambulance, Mountain Rescue)
Private Mobile Radio (Taxis, Security Guards, mobile service engineers, etc)
Cellular (Mobile) Telephone calls.
