Forum:How to get "trouble on the homefront" after beating the purity quest for xbox360

so i beat both sets of jefferson quests went near the vault to look for the radio signal and cant find it. i havent completed point lookout but have visited it i dont know why i cant get this to work

ah it is possible that you have missed it; FalloutWiki says that the quest is timed, and if you miss it - it's gone forever; it becomes available right after you complete Waters Of Life - simply travel to Megaton and check the Radio signals - and you should see a Vault 101 Emergency Broadcast

if you don't do it soon, the signal disappears, so it is possible that once you have completed Waters Of Life and traveled to Point Look-Out (which takes a month or so game-time to get to) - the quest has "timed out"

as far as I can tell, this is the only quest like this
