Ben, NO5K, also ran some LPF Transmission Charts on a "pristine" V3.0 board followed by ONLY changing the the relays to AXICOM relays .....same fixture setup, same cables, same test gear. The plots show somewhat better harmonics reduction with the AXICOM relays but the rolloff (a filter characteristic) is basically the same between the two as you would expect them to be.?
As I mentioned earlier the AXICOM relays DO show improvement but it's not the whole story.
The attached charts are small, but can be expanded. The goal is to get the general idea.??
