The Arc Raiders Ruins and Reverberations quest follows up on all the messing around with antennas from the previous Wires Crossed mission, as now you have to go to Pendola Pass Observatory and set up a Spotter Relay on one last antenna. In actual fact that there's a few steps that evolve out from that point once you've started, and finding the Spotter Relay isn't the easiest thing in the world either, but I'll lay out everything you need to do for the Ruins and Reverberations quest in this full walkthrough below.

Ruins and Reverberations in Arc Raiders has you go to Pendola Pass with the goal to connect a Spotter Relay to the antenna on the roof of the Cielo Sereno Observatory, but in reality there's a secondary challenge that spirals out once complete that first quest that you're not told about. You also need to get a Spotter Relay if you don't already have one in Arc Raiders, which is its own challenge.

Spotter Relays are, suitably enough, dropped by Spotters when you kill them. Spotters are the circular flying drones that hang around Bombardiers and mark players nearby. They're very easy to kill, but the danger is that if they see you, the Bombardier will try to kill you with arcing explosive mortar shots.

It's best to make noise far away to draw the Spotter's attention, then use a stronger weapon to try to drop them before they can spot you. If the Bombardier works out where you are, hide and wait for it to move on before searching the Spotter wreckage.
