Final answer:
In the 3D1X3 RF Transmission Systems career field, responsibilities include installing and maintaining various communications systems and testing equipment for compliance. However, maintaining wireless phones and cell tower equipment is not typically within the purview of this role.
Step-by-step explanation:
The career field in question is the 3D1X3, commonly known as RF Transmission Systems, in the U.S. Air Force. The responsibilities within this field primarily include tasks related to radio frequency communications.
Looking at the options provided:
- Installing ground radio, satellite, and telemetry communications equipment is indeed a responsibility in the 3D1X3 career field.
- Repairing, overhauling, and modifying communications and related equipment are also typical responsibilities of a technician in this career field.
- Testing installed equipment for proper assembly of components and compliance with technical orders is another critical responsibility in this field.
However, performing maintenance activities on wireless phones and cell tower equipment is typically not a responsibility of the 3D1X3 career field, as their focus is more on defense-specific communication systems rather than commercial cell phone infrastructure.
