When I get pixilation is when I plug in the HD box into a 3 way splitter and use the -7db leg on it. Then the tuner signal drops to around -12 dBmV. Another channel I watch is CP24 and the signal values at that channel is:
It looks like the readings on my modem (DCM476) is really good as it is at 0 db and the return path is decent as well.
In the past, I have added a 15dB amp to the mix (got it from Rogers) and that over boosts the lower frequency channels and my HD boxes in the house start locking up.
Does Rogers use Unity amps (ie. signal gets split and amplified at the same level so the net effect is 0)? This way the signal coming in is neutral and does not boost it.
the setup at my home is as follows:
Line goes from the TAP into the side of my house which has a 2 way splitter.
One leg goes into the basement and then goes into another 2 way splitter which feeds my 2 HDPVR boxes.
The other leg goes into my bedroom which has a 3 way splitter:
- 3.5 db goes into the cable modem - 7 db goes into one HDPVR box (this is the connection that I have pixilation at times) - 7 db goes into a digital terminal box.
I have booked service call with rogers but I am not sure what they can do. My experience with Rogers techs is that it is a lottery on getting someone who knows what to do. Last visit someone put a 15db amp and then added a -16db attenuator and it caused my return path to shoot to about 50 db and really didn't make the signal any better and make things worse!
