I think I can make NEC-2 work for this. It is a wire antenna modeling
program but I can make it do much more.

David,
Thank you for your response.
It seemed counter intuitive that the second approach would
have less crosstalk than the first.
That expectation is based upon picturing the fields between
the two signal traces as better contained when the traces
were side by side on the same layer, than i
Robert,
The second PCB stack-up will give less channel-to-channel crosstalk. Imagine
the stack-up with the ground traces on layers 2 and 3 removed. The coupling
of the layer 2 and layer 3 traces will be almost equal to the adjacent
channel. The ground stitching will help a lot. But you need to kno
