On AO40 Leila would definitely tell you if you were too hot on the uplink. But, it wasn't unreasonable...good times.
Oh....to think about squint angle (of the directional satellite antenna pointed at your location vs your receiving antenna. Good times they were

This is a great example of where a digitally processed (DSP/SDR) transponder would excel.
Assuming that any one uplink signal didn't crush a sensitive receiver/ADC with good dynamic range, it could process all signals in the pass-band and AGC the problematic ones before sending the signal back to an output DAC/filter/PA.
I never AO-40, so I haven't experienced LEILA in action, but the idea would be similar. "Quieting the alligators"
