Ok, Here is another theory..
There are 4 huts, and 4 characters
Does each character have their own hut?
Richtofer = Doctor's Quarters
Dempsey = Communication Hut
Takeo = Fishing Hut
Nickolai = Storage ( I think its called storage because that is where the meteor is being "stored")
Maybe the corresponding character needs to activate the radios in their huts to unlock a transmission? This is just a theory and I need to test it out.
