Cheap, licence free, radio modules are widely available, but are generally country specific - I would suggest checking what the situation is there?.

Again, you need to check in your specific country, in particular the regulations governing such things, they will probably be specific licence free frequencies you can use - but you may have to use commercial modules!.

Generally there aren't many circuits about, mostly because they are so cheap to buy, and because of the constructional and alignment problems at such high frequencies.

Have a look at https://www.rfsolutions.co.uk/acatalog/FM_Radio_Modules.html for one manufacturer of modules.
