I still say a Faraday Shield is all you need. It may only needs to be on that 'connected' wall, but I'd put in all the others except for the one between the console and the ISS. And don't forget the ceiling and floor! It could be one of those ground squirrel critters and his own radio system! One of those "internet of things". 
Faraday, schmaraday! Last time I went to the trouble of making a faraday hat, my hair stood up.
I think you've got it, Edouard! I guess Davis never envisioned someone using their Envoy as a repeater. Seems obvious now, but it sure was a mystery there for awhile!
Looks like I am chasing you around the forum this afternoon. Hope your weekend is a good one, my friend.
You know, I'm starting to love the 21st century a lot. This afternoon, my grandson, Logan, and I played for an hour or so over the Internet. He's in the Houston area, right on the Gulf waters, in a motel with his family. Together we have been in a longer term build process over the past week or so. We were making ourselves a home built into the side of a cliff in mostly granite rock. I had tamed a horse. He had planted a garden of wheat. We had been mining a lot for coal that we were using for heat and to make torches for lighting. Every night, with the darkness falling across the land, the zombies, skeletons, creepers and spiders would come out in abundance, and sometimes we'd go on a killing spree to get rid of them.
Anyway, today I logged in before him and set about making and marking a trail over a couple of hills and through a thick forest. I cut a lot of timber; birch and oak mostly. But, I did run into some spruce before I got done. That caused me to gather an unusually large amount of wood. At the same time, my landscaping activities and making windows for the house led me to stock up on plenty of stone. I didn't know at the time that soon I would really need a lot of those materials.
The first path I chose to open up, I went West, away from the rising sun. I hadn't gone very far before I ran into a flying creature I'd never seen before. The game told me it was a Wither, but I didn't know what a Wither was. Well, it seemed to be hostile and it was in my way, so I tried lobbing a few arrows into it to see if I could kill it. I soon found that it had more fire power than I did, so I had to back off. I went back to base camp and chose a different path. The Wither was to the West. I decided to go North.
After I had been working for awhile, Logan joined me unexpectedly. He was running around doing this and that, wanting me to watch while he killed something. Turned out to be a slime. Not interesting! And, it kept me from working on my project of the moment. But, in the conversation, I was reminded of my encounter with the Wither. I just couldn't remember what it was called, so I was telling Logan about this thing that flies and throws bombs. He didn't know what I was talking about. He's 10. ? So, I made him follow me to the place where my first trail was to end, to see if the thing was still there. I was going out ahead of him. It looked like he had stopped to pray, but I suspect he was just going to the bathroom or something. He was kinda far away by then. All the while, I was quizzing him about how to kill it. He though, by my description, that I was talking about a Ghast. When I got close enough to get the name and called out Wither, he immediately started to adopt that "I'm sorry Grandpa." tone. Someone had told him how to make it. He is the Server Administrator, so he has privileges that the regular players (me) don't have. He had made it a while back and then forgotten about it, especially since it was in the woods far from home. Actually, it wasn't that far. It just seemed far enough away to not worry about it for a 10 year old.
So I said, "How do you kill it?"
"You just shoot arrows at it." He replied.
Well I was close enough, so I notched one and sent it flying. It was slightly behind some treetops. My arrow hit, which seemed to annoy it greatly. It sized me up and fired, but the weapon harmlessly hit the top of the tree. I notched another and let fly. It got angrier! It was making noise and trying to clear its way around the treetop. I let off another arrow. I could see that I was doing a little damage, and I figured Logan would be there to help soon.
Just about the time the creature made his way clear of the treetop, I heard Logan bellow out, "RUN POPPAW!"
So, I turned and let out running. That thing was hopping mad, because it chased me all the way back to the house, pelting me with bombs all the way. I ran up inside the house just in time to turn and look out the window. Logan was still out there hitting it with everything he had in his arsenal! Which, was really just an enchanted bow that fires flaming arrows. The Wither's bombs were landing everywhere. I had just built a pen for my horse in front of the house. The wither blew it up and killed my horse! Well, that made me mad! I went to the side door of the house and tried to use the mountain side as cover, slipping out just enough to get the Wither in my sights and let off another arrow. Bombs were landing all around me, taking away the yard and sidewalk under my feet. I fell down in a gaping hole and had to scramble to get back around to the front door to get back into the mountain house.
Logan was shouting into his microphone. "Poppaw! We gotta escape to the mine. Get all your valuables. Come with me!"
I could see that he was now running around inside the house, in a panic. But, I wanted that Wither! Two things I had just learned. 1>The Wither was healing himself slowly. If we were going to take him, we were going to have to be relentless. 2> His explosions, though they were devastating to our environment, were only doing minimal damage to me. I was wearing diamond plate armor. I was loosing a little health with each blow, but not as much as I had thought.
Back to the side door I went and began pelting the creature as fast as I could. I wasn't going to let up! Again, he knocked the ground out from under me. I was back in a hole, but I kept firing when I could get him in my sights. Trying to get a clean line of sight, I retreated into the front yard, turned and fired again. Soon, I noticed Logan had joined me. He was firing. I was firing. The Wither was firing, but it was taking damage faster now. I was loosing health! Getting down to one heart left, and it was hard to keep the Wither in my sights long enough to hit the target, but I kept going. Then, as suddenly as it had begun, it was over. The Wither was dead.
The yard was cratered everywhere! There was a giant hole in the house where the side door used to be. And, Logan was apologizing profusely.
Suddenly I started laughing! It was such a relief. I told Logan, apology accepted. Only one apology was necessary. You play and you learn.
Great weekend indeed!
Hope yours was equally as much fun!
