This location consists of a relay tower surrounded by a chain-link fence. A terminal, also inside this fence, can be used to extend the satellite dishes, after which three radio broadcasts become available. The tower is commonly inhabited by mole rats.
- Distress signal, a cashier in the jewelry department of Fallon's department store who got trapped in the basement store's safe room after the Great War. She sent out a radio message asking for help before she died of dehydration and starvation.
- Miller family radio signal, a cry for help to turn on the ventilation in the locked up basement at Big John's salvage.
- Supermutant radio broadcast, a poorly scripted transmission by super mutants and read out by a female trader, who was captured and forced to entice other humans to travel to Shaw High School to inevitably meet their demise.
Relay tower 0SC-527 only appears in Fallout 4.
