CH:3 for TILT control and Highest CH in the band for GAIN.
I also like a FSM with the possibility of seeing the selection of 8 channels that I can have a look at at the same time, that also give me a good idea of the PEAK & VALLEY of the system.
64 QAM has to be 6 dB down on those 2 analog channel.
256 QAM has to be 10 dB down on these 2 analog channel.

This picture were taken at my home.
GOOD LUCK.
