Where do I learn about Signal Strength?

09-26-2007, 06:54 PM
Where did everyone learn about Signal Strenth? It is not in my manual and I cannot find it on the DirecTV website.

Is there a good thread that I can read or can someone give me a quick tutorial? I wonder if a suboptimal signal strength is causing me to have worse motion blurring than I should have.

What do the different transponders mean and what's the diff between Tuner 1 & 2? Essentially I need to know when and if I should call a tech to come by.

Transponders are where specific channels come from. So many channels per transponder. You are seeing tuner 1 and 2 because you probably have a DVR. This is what allows you to record 2 channels or watch one and record another.

You probably wont see motion blur from a poor signal. It will be more like audio/video drop outs. What are you signal strengths? 80-99 is great, 70-80 ok (might get some rain fade) and less than 60 is what I've been told is what Directv considers poor (re-alignment required).

Hope this helps.

Pretty much every trasponder is between 80-100 except for

Satellite 90b

6 45 39 30 35 0

Is this ok? thanks...

90 is for locals. If you are getting locals with no problem, then it probably isn't an issue.

I believe 90b is a spot beam. If you are near a city receiving the spot beam then you will see some spikes in the signal.

There is not a 90b satellite...I think you meant 99b. Not much to know about signal strength, other than it should be above 80 for the transponders you are getting channels with.

Sat 101 is the primary location for SD channels
Sats 110/119 have HD channels and SD locals
Sats 99b/103a have HD local channels and HD regional sports
Sat 103b is for the new mpeg4 national HD channels
Sat 99a is the next sat for mpeg4 national and HD locals

Signal strength has nothing to do with picture quality. It is a digital system. The data either arrives or it doesn't. If you have experienced loss of signal during a weather system then you how things behave with low signal strength.
