I guess I'll verbalize what everyone is thinking, that this cap approach is a supposed improvement of the sigcon scheme. I say "supposed" only because although it seems like a good idea (use the chassis only at RF) but it often seems that in EMC suppositions aren't good for much.

We could hope that they measured it both ways and this tested better...

Default use the chassis only at RF

The sheild is not actually the chassis. After reading 4 books and a dozen artlcle on EMC, I found a spectrum analalyzer, an X-acto knife, and some copper tape were still useful tools in my quest to reduces EMI and noise in the circuit on my last project. Simulation and theory are no substitute for good test equpiment but are a great supplement!

Sorry for the inexact language Harry. I was somewhat using the terminology of the sigcon article, which I guess does not correspond exactly with the board in question. Didn't mean to create any confusion.
