After agreeing to help General Ward, the player is told that Sergeant Peterson will join them during this task. Talk to Peterson and tell him you are ready to start. Peterson will jog to his locker to retrieve his gun, and then start following you.
You must now make your way to the Radio Facility. To leave the Vault, make your way to the cave. Instead of making your way back up the tunnels, look left. The previously inactive Elevator is now functional, bringing you back to the cave entrance.
The Radio Facility is directly West of the Vault. Follow the quest marker to it, and prepare for combat as you will find a band of Raiders have entrenched within.
Once you've defeated the Raiders, enter the facility. The quest marker will point towards a Terminal. You'll want to use the terminal and select Establish link to Vault 111.
Exit the terminal. Sergeant Peterson will warn you that a Raider Counterattack is about to happen. Heal yourself and loot any equipment you need, as you will have to defend against a large number of raiders. Tip: The terminal you just used will allow you to enable a Facility Defense measure at a time. You can:
- Enable Turrets.
- Close the Window Shutters.
- Close the Door.
You can enable each option at will, but keep in mind it will disable the other two.
After you've fended off the Raiders, make your way back to General Ward in the Vault. Speaking to him, he will reveal that even though the Facility was successfully linked to the Vault, he recieved no responses from Command. A silver lining to this, though, is that he discovered the location of a nearby Vertibird Facility with a supposed Vertibird within, and asks the player if they can go to the Facility to confirm if that's true, starting Grounded Bird and completing Calling Home.

- The quest doesn't progress after fending off the Raider Counterattack.
If for some reason the quest doesn't register that you have fended off the Counterattack, open the console with the tilde key and typing in: setstage ARMQ02 20.
