Richard,

It's not clear what aspect of your sources is "Rnd", but the fact that
they are monochromatic is still problematic.

Very nice work. Dissapointingly ambiguous results.

Thank you.

(and really see what's going on)



Hmmm, at least 1000 times more response... so what's going on? (aside
from a possibly poor implementation of random). Trying to refine the
sources table with tighter random assignments is positively brutal
under EZNEC's primitive (read no) handling of columnar data.
