Hi Magnethos,
Essentially a bifilar coil is pretty much a double wound coil. Instead of using one wire you use two wires of similar or slightly different thickness and wound it around a spool.
There are many techniques that will enhance the effectiveness but lets stick to the basics for now.
Imagine winding a single wire coil around an empty fishing line spool. When you are finished you are left with two wires. The end that you started with and the end that you finished with.
Now imagine winding two wires at the same time around another spool. At the end you are left with 4 wires, two wires you started with and two that you ended with.
There are some nice videos on YouTube that show you exactly how to wind bifilar coils. Actually thats how I started out.
Now in NRG's circuit diagram he shows a bifilar coil but with only two wires which is actually 4 wire ends joined into 2 groups making two wires.
I hope that makes sense.
For now consider winding the bifilar coil first. My first coil I still use. Its approximately 300-350 turns around an emtpy fishing line spool. I used 23 and 26 gage wire to wind it.
Let me know if you need some more info.
Cheers!

man you beat me to it. Can you share some details of your test setup?
