The WavePhoenix Mini Receiver is a small, low-cost WaveBird receiver replacement. It has been designed to be as cheap as possible (~$4 in parts) and simple to build.
The receiver uses a cheap, off-the-shelf wireless module (the RF-BM-BG22C3), which can either be hand-wired, or assembled onto a custom PCB.
