Head to Abernathy Farm and talk to Blake. Continue asking him questions until he mentions his daughter. He will then ask you to retrieve the locker from the raiders that killed his daughter. The location will be marked in your map so make the necessary preparations and head to USAF Satellite Station Olivia.
Clear out the raiders outside then head deeper inside. Ignore the locked security door for now. It's up to you if you want to sneak or go out loud. Be warned though since there's a named raider called Ack-ack equipped with a minigun inside. After killing them, you'll find the locket in the red toolbox beside a locked blue door.
If you unlock the Novice door behind the toolbox containing the locket, you can get a special weapon called Junkies' Pipe Rifle by killing one of the large radroaches there. Inside the room, you'll find a Novice Wooden Crate and an instrument case containing the key to the Intel Room. This is the key for the locked security door earlier.
After looting the place, return to Blake and hand over the locket to complete the quest. You can now use the workshop in the farm and modify it as you much as you want. This will become one of the friendly settlements in the area.
