Dave,
Yes. In other words, just as we would wind in sequence around a toroid.
It limits the number of useful turns that can be wound to one side of
the clamp. Once I realized that, I no longer recommend the clamp-on for
TX chokes, only for RFI suppression.

Jim,
When you said “turns must go through the core in sequence”, does that
mean that each turn must rest next to the last one, rather than
overlapping one or more previous turns? I suspect that’s what “in
sequence “ means- just want to make sure.

No. See my post in this thread about resonance.
BTW -- I strongly agree that clamp-ons should be secured with a
ty-wrap.
And something I missed the first time around, but corrected in the
latest version of RFI-Ham is that turns must go though the core in
sequence. Out of sequence turns cancel in-sequence turns. Learned this
from some measurements.
