Frequency Hopper Synchronization

[Frank Eliot]

Jim -
	I like your solution. It might take a bit longer for the initial synchronization, but much easier to perform the frequency sampling, which makes the hardware simpler and doable. The coding logic becomes a bit more complicated, but that is just software!
