I am working on my project - HOME SECURITY SYSTEM. For that I have to design RF transmitter receiver pair having 25m range. Toy car wireless ckt have enough range and i have one provided by web below:

But some of its parts are not clearly visible, and not properly mentioned.
So if you have enough information about this ckt or any other diagram than plz help me.
