Automatic Scan Operation checks which channels?

Automatic Scan Operation checks which channels?

• A. Cipher Text only
• B. Cipher Text and Plain Text on LOS fixed frequency or dedicated UHF SATCOM channels
• C. Plain Text only
• D. Random channels across bands

Answer: (B)

Automatic Scan Operation is designed to quickly assess the nature of transmissions on designated channels. It checks both cipher text and plain text on line-of-sight fixed-frequency channels or on dedicated UHF SATCOM channels. This dual check is essential because it verifies whether communications are properly encrypted (cipher text) and also flags any unencrypted activity (plain text) that could pose a security risk. Limiting the scan to only encrypted traffic would miss unencrypted transmissions, and looking only for unencrypted transmissions would miss encrypted ones. Scanning is targeted to specific LOS fixed frequencies or dedicated UHF SATCOM channels, not random channels across bands, making it the most effective way to ensure channel security and proper usage.
