Resonance

Resonance is the second main quest in Fallout: The Board Game if following down the institute path

Walkthrough
After manually finding and killing synth, the party obtains a synth transponder allowing them to track the coordinates of the location of the Institute

Institute Path
Now with the transponder, the party can get inside the Institute if they use a quest action at the C.I.T Ruins, if they have Endurance and Intelligence, they may attempt the check with up to 2 rerolls. Completing this path will lead to Uncover The Railroad

Railroad Path
With the transponder and some bargaining skills, it may be easier to get information now with physical proof of the internals of a synth, the party can do a quest action at Diamond City and spend 4 caps to progress further. Completion of this route will lead to All Hell
