Thank you so much for your three replies! In my humble opinion, stacking cores and using the same number of turns will certainly increase the inductance, but I don't think it will double the inductance. You see, when you stack and wind the the same number turns of wire, the total length of wire will increase, but less than double. I think other factors will not change, therefore, I believe the inductance will increase to some extent less than double.

BTW, is WN3L your ham radio callsign? My callsign is BG6CR!
