The origin of the signal is a ham radio in the reactor level of an operations building. It is directly to the west of the relay tower on a dam and can be recognized by its blue door. The first room of the building holds not much of interest except for a wooden crate next to the entrance, but in the back of the room is a hatch leading to the caved in reactor level behind some cardboard boxes. The ham radio can be found directly to the left in the reactor level.
- pc ps4 This signal and the nearby distress signal and garbled radio beacon may not turn off when their original ham radios are turned off by the player. Leaving and re-entering the area may resolve this.[verified]
- Reactivating the nearby Relay tower 1DL-109 (twice) resolves the issue.
- pc ps4 At the Locks, the deep water is not registering as water, causing damage to be taken if jumping off the lock doors into the water. The player will hear sound as if underwater but is unable to swim, nor takes radiation damage, and will be able to use weapons as if the player is on dry land. Moving underwater towards Forest Grove marsh the player will enter "real" water and start taking radiation damage and start swimming.[verified]
