These links should get you going for a while:

My handheld disk-tool to figure out AOB/course (only): sit still, take bearings and wait, slide the wheel and know which way he is going

A pretty clear document describing a technique to get position and course (and speed if you divide the sections between the bearings with the time interval):

Another, document describing a similar technique (different geometrical steps, same idea):

[EDIT] I wouldn't call this 'basic'. That would be simply homing in on the direction of the sound, surface and sprint, while ever so often adjusting the course after you take a dip to listen. These methods above are the smart 'advanced' way of doing things. A bit more patience is required, but the result is a solid solution. (as best as you can measure the bearings though) And these methods are not neccesarily historically accurate. But in the game they do work!
