Re: [TIVO] Signal Quality problems Actually, tonight is one of the coldest nights in forever.
And if I'm not mistaken, colder temperatures will mean less signal loss and hence a "hotter" signal, requiring the attenuator?
I saw mention in another thread of a variable attenuator from radio shack, but could not find it via their web site. Anyone have a direct link or information about cost?

The Verizon tech left me some after install for free. I imagine a local Radio Shack will have some. |

kudos:3 | Thanks for the link. $13 isn't bad.
Out of curiosity, what is the target SNR and/or "signal quality" on the S3 Tivo "DVR Diagnostic" page? I'll use the reported SNR at the cold times and warmer daytimes to figure out which attenuator to start with.
Thanks again!

Villanova, PA | Folks have reported 31 as the target SNR on the Tivo. I just went based on viewing experience. If the Tivo pixellated I would add more till it stopped on the offending channel.
Supposedly the S3 handles this better than the TivoHD, so you may only need a small amount unlike me. In my old house, I only needed around 6db of attenuation. It all depends on the ONT and cable run.
In my new place, I have about 15ft of coax from the ONT to the Tivo. In the old house I had about 150 ft. |

kudos:3 | Ok, thanks. I'll start with 3 dB and go from there. It's ok to daisy chain these, right? If so, the possible values I can try given 2x3dB 2x6dB 2x10dB and 2x20dB are:
3
6
9
12
13
16
19
20
23
...
I'm guessing I won't need more than 3-9, so the other values are just theoretical.

Yes, you can daisy chain, but you most likely won't need to. This isn't an exact science really. |

kudos:3 | Yeah was just thinking if 6 didn't cut it, I could go to 9 instead of 10... 
Thanks! |
|
| The difference between 9 dB and 10 dB of attenuation is:
-9 dB is 1/8 (0.125) the original signal strength
-10 dB is 1/10 (0.100) the original signal strength.
The world would little note nor long remember the difference

Deblin,
Yes, with a Tivo, this can happen overnight.
One of the main reasons I sold mine. I couldn't stand the unpredictable pixellation.

JeepMatt  do you know of any local vendors that would sell the attenuators? I REALLY want this fixed by the Eagles game Sunday...

If you can't find them locally, you can always use some cascaded splitters as a temporary fix. They are marked for their loss (attenuation) to each port - the more ports the more attenuation. Not meant to be a permanent fix, but it might help for the game and be simple if you have any "spare" splitters around - GO EAGLES.

If you know where the Verizon garage is located go there around noon or close to 5PM and find a tech or supervisor and ask them for some.
The other alternative is to drive around until you find a Verizon truck. That is hit or miss, because you need to find someone from the TV crew. |

Basically a terminator is a 75 ohm resistor that shorts the center the shield. |

Does night vs. day matter? Because I'm tuning a few HD channels that would normally have this problem (fox, cbs, etc) this morning and they're fine.

You should try and get a tech out. DE usually has a quick turnaround. I'd just say you're losing reception (and the eagles are playing this week) and see how fast someone could be out.
You may be able to get someone there by tomorrow.

1 edit | They do Saturday tech calls? Sweet!
As I was writing this, I saw some pixelation on Fox, and I'm seeing it now on channel 514 now. So the issue IS still there, so disregard
Guess I know what I'm doing with my lunch break today! Need to find me some attenuator pads! |

I took a quick ride over to Middletown Electronics (says Radioshack, but I think it's its own entity now).
Anyway, do you know of any stores to try calling in the Newark area? Or I guess even Wilmington.
Thanks man!

kudos:3 | So a splitter as a temporary solution to drop the signal will only work if all the unused (be it 1 for a 2:1, 3 for a 4:1 etc) connectors are terminated? 
I'm in the same boat then...can't get these terminators locally, have to order online. Same with the attenuators. Sigh.
Guess I'll watch the Eagles game in SD.
