OU nub here.

Just some questions for the researchers doing a ronotte type configuration with a single collector. I'd like to verify what it is you're doing.

Just so we're on the same page, correct me if I'm wrong: this is the configuration with one big loop of thick wire called a collector, with 6 individual coils wrapped around the big loop, all with the same winding direction, with rotational symmetry about the collector center, and parallel connections between coils on opposite sides, such that magnetic flux directions around the collector of each coil in a pair oppose each other. Then drive each pair of coils at a different frequency, so there are 3 'magic?' frequencies. Output terminals are the ends of collector wires.

Question #1. Some of you are using PC sound card signal generator software. But, referring to this ronotte/twosox configuration, if you need to drive 3 coils separately with different signals, how does this work? Stereo channels, Alpha(left) and Beta(right), (obviously sharing ground) for two of them would work; what about the 3rd coil?

Question #2.  You are using some mosfet or transistor or something controlled by the signal generator to power the coils, right? What (max or avg) voltage, or current, are you using as your source? (9v sounds too high...melting insulation or killing battery with low impedance coils and 'high' current...)

Question #3. The collector is just a thick copper wire? (or iron i read?) AWG 10 or so?

think you will need a multichannel soundcard. or you could burn one channel to a cd i suppose.

All:
   I have tried to use the sound card gens and although it works sort of, I do get a lot of junk on the lines as well from the computer.
   Three 555's driving fets will give you a lot better signal quality. That is what I will be going with for now.

The pc scope and spectral analyzers do work fairly well tho.

sugra..
sure i suspect using digital osc is not a great idea.
i think analog osc will be what you need.
