Not exactly what you are looking for but
http://groups.yahoo.com/group/softrock40/
is dedicated to Software Defined Radio.
The collection of transceivers here work in conjunction with your PC 
soundcard to provide a complete rig at very low cost and very high 
performance. Receiver only in the neighborhood of $10, transceiver in the 
$30 range for kits.

Otherwise Google QRP transmitter.
