Hi David, When I say particles, I mean powder, ok? It's not a Faraday cage as we understand like a box, because all the air there is surrounded by the dust when machines are working. Thanks for your interest and cheers. Ricardo

Nice story Ricardo.... but how big were these graphite particles? My understanding was that to interfere with a radio signal the interfering particles had to be around the same size as a 1/4 wave of the signal (for instance I know raindrops falling elongate to around 1/4 wave size for 12 GHz satellite signals). I guess they could also form a kind of faraday cage round antennas though. We had a guy here once who set up an infrared data link between two buildings. It worked beautifully and he was very proud of himself. Then one day there was a thick fog and the link wouldn't work. He hadn't thought of that.....
