Smudge, thanks again, i will concentrate first on the toroid. I distributed the turns around the nanoperm core so they were evenly spaced along the whole circumference and used a 56 Ohm resistor across the output where i measured the both wires with my yellow/blue probes referenced to ground. There was an amplitude unbalance, see first screenshot. So i used another toroid from ferrite and more turns of similar cat 5 wire pairs. This measured 3.92mH for each wire (the nanoperm toroid measured 54.8mH) But also this ferrite toroid shows (even more) the amplitude unbalance, see screenshot 2. We do have the almost 180° out of phase condition, so that's ok. Video here: https://www.youtube.com/watch?v=R4vc23FFXYI&feature=youtu.beAny idea what is causing this amplitude unbalance? By the way, when increasing the FG frequency there are some points where the amplitudes get equal, but then the phase shifts are less see screenshot 3 when at 13MHz Regards itsu
