My colleague concludes >that groundplanes are not required. Do you agree with the conclusion? There is a requirement in the last paragraph of 7.3, which is, in effect, a ground plane, and there is another in 8.2, and another in 8.9, and another in B.2. I think you have to look very carefully through the standard (and do a word-search if you have an electronic copy). -- OOO - Own Opinions Only.
