first do mission 6 (in chapter 1). Then do mission 8 (chapter 1) and talk to Jane in the first room. This will trigger a faux-invasion back at your shelter, and you can just leave the mission after finishing talking to Jane. )
i mentioned I had already tried that it doesn't trigger anything for me but then I have all the champions / women and jail built etc. If I do quest 6 then 8, nothing happens. I thought the whole point in the radio was to get invasions but its never triggered any.
