I should know the answer to this question, but maybe someone else knows it
off hand...

Are there some part15 rules that allow license-free microwatt emissions or
whatever on these frequency bands?  With the gain of these dishes, even a
few microwatts could make a usable pt-to-pt link.  Also with the 1 degree
beamwidth, the chance of interferring with anyone else is near zero...?

Now, how to generate a stable few microwatts at 12 GHz!
