Core Material Composition

The mix is to complicated for a home shop project. There was a TRB member or two playing with home shop mix so I posted this for information only.
This is the material that has worked best for me thus far. I wound one of the smaller cores last night and it was a good performer. I didn't have time to do a good test but it was picking up signals when I flipped the power switch. I heard a couple CW QSO's and some SW stations as I sweep the bands.
