Technician exam question T8B12

WhyTo check that your uplink power into a linear transponder satellite is neither too low nor too high, your signal strength on the downlink should be about the same as the beacon's. Since a linear transponder retransmits every uplinked signal at a similar relative strength, comparing your own downlink signal strength to the satellite's beacon gives a direct, reliable check that your uplink power is in the right range, neither so weak it's barely audible nor so strong it's overdriving the transponder, answer C. Signal strength isn't reported in the telemetry stream (A), listening for downlink distortion (B) only catches the problem after you're already overdriving the satellite, and comparing to other stations via an internet SDR (D) is a roundabout method compared to the direct beacon comparison.
