I've never seen any circuits on the net for them, generally you need special chips to do it (or lots of more common ones), and the low price you can buy complete systems for makes it cheaper to just buy one.

You also have the problem of RF construction, which can be quite difficult to get right, far easier not to bother.

Ome of the most common RC chip suppliers...

Pericom Technology Inc
Devive Number --- PT8A995 (TX) and PT8A996 (RX)

Allthough no artwork for the demo board pcb is to be found they do give the component overlay/layout wich can be reverse engineered to find the track layout...
