Deep Range Transmitter

The Deep Range Transmitter or DRT is a quest item in Fallout 4.

Background
An advanced piece of pre-War technology, the transmitter was developed by ArcJet Systems for the Mars Shot Project. Although preliminary work was completed, culminating in the creation of a working unit, a scientist reassigned away from XMB fuel mixture work managed to boost its communications range by 70% inside three weeks, allowing the NSSA's ship to ping a signal back and forth within ten minutes, while eventually managing to reduce the unit's size by half to match the target volume.

Location
It is located in engine core of ArcJet Systems, on a synth.
