Right. But how big is the search space? I think that depends on how fast you are hopping and the max distance you consider reasonable. A mile is 5000 ns or 5 microsecond. If you hop every ms there are 200 miles per slot. If you hop every 100 ms there are 20,000 miles per slot. If I pick a max distance of 1000 miles, that's 5 ms. If you are off by half a slot, that will be 3dB down in the digital world. It would probably be pretty ugly in the audio world, but it would be easy to tune with a knob. Actually, you can know the distance in advance for some games. Suppose I'm going for the low power record from point X to point Y that are line of sight. ... -- These are my opinions, not necessarily my employer's.
