hellooooooo.....yep, you have to first decide whaty you want to do with the RF boards. Two way radio, to control models like boats and sailboats or even cars. Or perhaps to use them in wireless alarm systems. In other words, you have to decide your encoder/decoder. Yung manchester codes available sa isan IC 145 something. I have done some experiments on them.
Now, the range is quite limited, 400 feet. better siya than those China made UHF wireless doorbells which can only go about 70 feet.
If you will tell me what you want to build, I may be able to help. My expertise is in RC transmitters and receivers on 27Mhz to 75Mhz, AM or FM.
What does the HT640 do?
