After retrieving the Courser Chip, go see Doctor Amari at the Memory Den in Goodneighbor. She will recommend that you contact The Railroad.
NOTE: If you have not contacted the Railroad at this time, you must complete the quest Road to Freedom. You will not be able to progress this quest until you do so. This quest is also your last opportunity to secure support from the Minutemen and Brotherhood of Steel so if you have not developed your standing with that faction, now is the time to do so. See the Quests page for quests related to the Factions.
When ready, enter the church to gain entry to the The Railroad base. Speak with their leader, Desdemona, and have the Courser Chip analyzed by Tinker Tom. Afterwards, you may leave this location via the escape tunnel so that you can remove the chain to the secret door. Doing so allows you easier access the next time you wish to return to their base of operations.
Return to Virgil's location in the Glowing Sea. After explaining to him the present situation, he will give you Signal Interceptor Plans.
Now that you have the plans in your hands, you can begin the process of building it. There are 4 ways to go about this, each presumes that you are in good standing with the respective faction. Note that each faction will ask you for information on the Institute, so if you plan on working with the Institute in the future keep these requests for espionage in mind.
Go to the Cambridge Police Station, taking out Feral Ghouls in conjunction with the Brotherhood of Steel quest Fire Support. Talk to Paladin Danse about the interceptor you plan to build and he will provide you with support after you complete the quest Call to Arms. You will be asked to provide info related to the Institution via the quest From Within.
Upon completing his request, you can speak to Proctor Ingram the faction scientist on how to build the signal interceptor.
If you have finished the quest When Freedom Calls, you can enlist the help of Preston Garvey. Head to his location in Sanctuary or the Settlement you sent him to and speak with him about the interceptor. He will ask you for some help in exchange and you will then have to complete the quest The First Step. You will be asked to provide info related to the Institution via the quest Inside Job.
Upon completing his request, you can speak to Sturges the faction scientist on how to build the signal interceptor.
Go to the Old North Church and speak with Desdemona about the interceptor. She will ask you to join the cause via the quest Tradecraft with the Companion Deacon before agreeing to help you. You will be asked to provide info related to the Institution via the quest Underground Undercover.
Upon completing her request, you can speak to Tinker Tom the faction scientist on how to build the signal interceptor.
You may choose to eschew the help of the Factions and build the interceptor yourself, at any Workshop that you have found. You will clear an area in one of your Settlements and begin working.

Upon finishing speak with your respective faction scientist to learn more about special materials needed for the beam emitter, relay dish and console.
- Rubber x10
- Steel x3
- Copper x5
- Military-grade circuit board x1 (can be found at military sites: looted from turrets and other machines)
- Circuitry x1
- Power x20
- Copper x3
- Steel x3
- Cloth x6
- Gold x3
- Sensor Module x1 (can be found at telecom sites or tall structures such as Trinity Tower and Revere Satellite Array. Warning, the Array is guarded by super mutants. )
- Power x5
- Power x2
Once all the components are constructed, access the generators in your workshop and build the generators you need to power the interceptor.
Building Teleporter Guide
Generator -> Generator -> Generator -> Generator -> Generator -> Console -> Relay Dish -> Beam Emitter
If you're worried about cable management, here's a clean setup :
(All the Generators) -> Power Pylon -> Console -> Relay Dish -> Beam Emitter
Sometimes when you adjust the setup, you will be unable to place the Stabilised Reflector Platform under the Beam Emitter. Try moving the Beam Emitter to an isolated spot, make sure that there is nothing underneath the Beam Emitter (eg. floors, rugs, etc.) store the reflector platform in the workshop then use the menu to place it underneath the beam emitter. You can then hold the place object button to move the Emitter and Platform together back to the desired spot.
