My best advice:
- Look at Ofcom or Comreg website and search "unlicensed broadcasters" if your worried about fines/prison!
- Search through the forum in the "Anorak section" their is plenty of topics to get an insight on equipment, how to make certain pieces of equipment.
Here's a link of a basic transmitter setup:

- Build a project ie: dipole antenna and plug it into your FM receiver, Tune around and see if you can find more stations, you never know you might hear unlicensed station near you?

You could skip these section but ideally it will help you get a brief understanding about some form of radio!
- Buy/fine a cheap "CB radio, SWR and Antenna" get practice wiring it up, solder on PL-259 connectors on coax, tuning the antenna. Loads of videos on youtube about this. But don't play music over it, scan the channels and speak to someone so you know you've got it working. Talk about your setup and ask them where location is and not that you want to become a unlicensed broadcaster.
(The reason I say CB instead of buying a broadcaster transmitter) if you learn with this you won't get raided as CB's don't need a licence in the UK and the last thing you want is trying to learn with a FM transmitter in you back garden cause interference to someone FM radio and grassing you up.
- Once you've learnt how to wire up a CB, tune antenna, then look at finding a transmitter. But you will struggle to find a half decent transmitter that doesn't cause interference cause most people buy cheap Chinese transmitters off ebay. I think if you show people on here a bit keenness on building something, Some radionecks member's might give you a better idea where to get stuff from?
