Why should effective radiated power (ERP) be limited to a satellite that uses a linear transponder?
To prevent creating errors in the satellite telemetry
To avoid reducing the downlink power to all other users✓الإجابة الصحيحة
To prevent the satellite from emitting out-of-band signals
To avoid interfering with terrestrial QSOs
الشرح
A linear transponder has one fixed output power budget shared by every signal in its passband, and its automatic gain control responds to the strongest uplink, so one overpowered station forces the transponder to reduce gain and starves everyone else's downlink. The concern is shared power, not telemetry errors, out-of-band emissions, or terrestrial contacts.
