"What is the recommended RF input level?
What is the maximum RF input level before causing distortion?
Is the Zenith DTT900 designed to output a constant RF output level
regardless of the channel it's tuned to?
Please describe the NOTICEABLE effects of applying too much signal to the RF input."

The output of all the CECBs are remodulated with what ever they decode.
The RF output RF energy out of a CECB is constant. The modulation on it varies by what it decodes per channel.

I don't know the overload point of the Zenith, but it's one of the more tolerant boxes.

However I do know on any box what happens with too much digital signal is a loss or degrading of signal quality.

Way too much the station won't decode. Moderate overload the signal quality meter reads lower.

If you have a directional antenna you can sense overload if turning the antenna away from the station makes the signal meter go higher.
