Detailed walkthrough
The player character can find another in a ruined house next to Knight Varham. The ruined house is north of Relay Tower 0MC-810, south of Greentop Nursery and east of Taffington boathouse.

The next may be found next to the corpse of Knight Astlin in the back of the National Guard Recruitment Centre. This is accessed by approaching the National Guard Training Yard from the East. Namely, by fast travelling to Revere Satellite Array, running west to the Yard, across the parking lot and through the door under the "marquee".

One can find the origin of one distress signal in the Revere satellite array next to Scribe Faris, at the top of one of the four non-central towers.
