I think it has been stated in a variety of ways by a variety of people
that the Faraday cage should be grounded, I can hardly believe this
hasn't been tried yet...
You guys are NOT reading the past responses or watching the videos. Of
course the cage has *always* been grounded. The black wire under the
cage is the ground wire. Ground loops have been identified and eliminated.
The only remaining thing to do is this. Given the proximity of AM
broadcast, not only at his lab in particular - but in any metro area- he
will eventually find the time, in order to quash all of this remnant
skepticism, to take the device, which is extremely portable - to a
remote area and ground it there as a final word on the issue, but he is
not at all concerned about this.
Give the guy some credit, please! He has been a Ham operator and FM
station operator back when many of you were pulling pigtails in grade
school. He understands all of this is greater detail than any
non-specialists here (EE grad).
