Hi,
it's really hard to make a RF transmitter and reciever . it's need a lot of experience. i think the best way is using modules, for example U2741B and U3741BM from atmel or you can use TXC1 and RXD1 from keymark company.(TXc1 and RXD1 are ready made devices). In your frequency(433.92MHZ), you should use SMD devices.
if you need more information ask me again.
