Is there any pattern to this, either fixed or random? Ever since they took the Jefferson memorial, I'm seeing them all over the place now with small satellite relays. Even stranger are the vertibirds, I've already found several all over the area that were being guarded by Enclave soldiers, at least one moment where they actually landed one and attacked me near Megaton, and up in the north east area near Raven Rock, you can see at least 3 that are just flying overhead towards some unknown destination.
