   how are they going to do that? If they’re not in the path between the   
   sender and the receiver, they won’t detect the maser. Remember that a maser   
   isn’t visible light and can’t be detected by secondary effects such as   
   light bouncing off dust particles; if the oppos don’t know what freq the   
   maser uses, they’ll have hell picking up any bounces. And, of course, with   
   no air, they won’t see the beam itself and wouldn’t see it even if were   
   visible light. This ain’t Star Trek/Wars. The first they’ll know is when   
   the relay point starts sending. Bit late then.

   that would work if they:   
      
   1 knew the right freq to use; masers are coherent emag wave systems, the   
   receiver wouldn’t detect anything on the wrong freq   
      
   2 knew where the relay was _before_ the signal was sent. A nice simple   
   passive lump of matter sitting somewhere clear of the ecliptic and not   
   broadcasting until necessary would be had to see... and then if there are   
   multiple such items, the oppos would need to send signals to _all_ them. Oh.   
   Wait. if two or more of those lumps are relays, then unless the oppos can   
   _destroy_ them at ranges measured in AUs, the oppos just told the friendlies   
   where they are and what their vector is.
