Which is not a SATCOM Interference indicator?

• A. Static
• B. Bleed over (voices power hum)
• C. Loss of communications
• D. Jammer light

Answer: (D)

When assessing SATCOM interference, focus on the actual symptoms you observe on the communication link rather than device status lights. Static on the line shows random noise that corrupts the carrier and reduces clarity. Bleed over or voices/power hum indicate leakage from adjacent channels or equipment, signaling that the signal is not clean. Loss of communications means the link cannot be established or maintained, which directly reflects interference affecting the SATCOM path. A jammer light, by contrast, is a hardware or system status indicator. It might come on if a jammer is detected or suspected, but it doesn’t consistently reflect the condition of the SATCOM link itself. The link can be degraded or even blocked without triggering that light, and the light can come on for reasons unrelated to current SATCOM interference. Therefore, the jammer light is not an interference indicator for the SATCOM channel, unlike the clear signal-quality symptoms of static, bleed over, and loss of communications.
