Can ROMEO receive and transmit J3.7 messages?

Can ROMEO receive and transmit J3.7 messages?

• A. Receive and transmit
• B. Transmit only
• C. Receive only, not transmit
• D. Neither receive nor transmit

Answer: (C)

J3.7 messages are a specific category of Link 16 data that certain terminals are allowed to receive and decode for situational awareness. ROMEO is configured to monitor and display these messages, but it does not have the authorization or the hardware path to originate or inject J3.7 traffic onto the network. Transmitting J3.7 would require appropriate permissions and cryptographic keys, which ROMEO does not possess. So ROMEO can receive and interpret J3.7 messages, but cannot transmit them, making receive only the correct capability.
