I think you'll run into a problem that you'll need multiple synchronous channels to do a direction finder unless you're planning TDOA. Don't know if its possible to use 4 tvrx modules, for example, in one application.
You could do a single channel DF where the antenna is designed to switch elements at a fast rate. You might be able to rotate the antenna elements via the PCs serial port or parallel port. As I recall the processing is just an AM demodulator. Have a look at this website for more info: http://www.directionfinder.com/rdf.htm. The technique is called watson-watt. Let me know if you come up with anything as I'm interested in DF also.
