The RT-1022/ARN-99 Receiver Transmitter does what?

The RT-1022/ARN-99 Receiver Transmitter does what?

• A. Only transmits signals
• B. Receives and transmits coded RF pulses, decodes received pulses to extract bearing, range, and ID tone
• C. Only decodes signals
• D. Controls cockpit lighting

Answer: (B)

This device is a two-way RF system: it both sends coded RF pulses and listens for responses. When it receives those responses, it decodes the information to provide three key outputs: the bearing (direction to the source), the range (distance to the source), and an identification tone (ID) that identifies who or what the signal is. This combination—transmitting, receiving, and decoding to yield bearing, range, and ID tone—is what the unit does, rather than only transmitting, only decoding, or performing unrelated tasks like cockpit lighting.
