Radar, Airfield, and Weather Systems (RAWS) CDC Volume 1 Practice Test

In the Joint Electronics Type Designation System, the three-letter codes encode the basic function of the equipment. When you see General, Radio, and Receiver together, that designation is GRR, which specifically means a General Radio Receiver. The first letter indicates the general descriptor (General), the second confirms the function as Radio, and the third indicates the type of equipment as Receiver. So the phrase that aligns with this code is General Radio Receiver.

The other phrases describe different roles or power sources and would map to different designations, not the General Radio Receiver code.
