Thanks for the detailed explanation of the graphs I could certainly follow it on the graphs.
I have 2 of the T130-2 cores but the only mag wire i have measures 1.90mm across
which is way too heavy to get 18 turns of 3 wires.
I do have a ton of coated 14awg gauge stranded wire or 14/2 electrical wire as well.
Can either of those be used in a balun at 100-150 watts?
Since the gypsy balun is trash and its sealed in a way the is not open able i would
like to get a balun wired on the core and perhaps at least use the connectors from
the trashed one, lol after likely having to saw it in half in the middle.
I got two cores i also want to make a 9:1 for playing with end feed wires as well.
