said by kmand:I went back and read the diag menus again on my Comcast/Motorola DVR DCH3416 and it deos indeed have OOB at 75,25mhz, above the 60MHZ limit of the filter.
However, it also clearly lists under upstream status "center frequency 10.976 mhz". Why wouldn't that be blocked since its above 10 and below 60?
The OOB is the frequency that the box gets all its data from the headend on. Whenever there are guide updates, softeare updates, etc they all get broadcasted over that 75.25 freq. 55Mhz and up is the forward so if you blocked that you would lose some analog video as well.
