said by Fordguy:In the faqs about lvls it says
all downstream channels should be within a +/-2db window with respect to each other
what would cause channels 4-7 to be so far off compared to 1-3?
I get the same difference weather connected as is or straight to the outside cable box. thanks again
Hey I am also from portsmouth myself, and some of your signal levels are borderline. But unless your having trouble nothing to worry about. The reason 3 of your downstream channels have lower power levels, is because them three channels are in the 500mhz range, while the 4 channels with -9 to -10db power levels is in the 800mhz range. So yes it is normal for these channels power levels to be different when frequency range is that far apart. As for me saying some of your signal levels are borderline, with D3 they want downstream power levels between -10 to 10db max, closer to 0 the better. Also your 800mhz downstream channels are on the low side with downstream SNR specs, which cox likes minimum of 35db. Anyways if you are having no problems, let it be. But if you do start to have problems, signal levels do have a little room for improvement.
