Thank you for the response.
I worked a lot on the trial yesterday, I started at 0 to work my way up to 99% on my weakest channel. Since I pickup from 2 towers one is 80 miles away and the other 9, the global setting was set to 6DbmV, and I adjust those weak channels with +3 and all the local at -3 ...

Hi just bough a televes smartkom device, the default output is set to 25 dbmV.
Can this value overload the input of the hdhomerun flex 4K unit?
What should be the ideal value to set?
