You should first understand that each channel is on a specific transponder on a specific satellite...there is no "choosing" of transponders other than selecting a channel.jdwatson said:
Statellites, Tuners, Transponders, Oh My !
Greetings !
I'm trying to understand how the H20 chooses things. On my 101 Sat the signal strength on transponders are:
101 Sat
-----------
01 - 06: 73 95 73 95 71 87 75 80
09 - 16: 74 89 71 85 67 88 00 79
17 - 24: 42 48 42 89 37 87 38 82
25 - 32: 39 00 38 85 39 92 82 87
110 Sat: signal strengths are always between 89-100 on all transponders
119 Sat: signal strengths are always between 96-100 on all transponders (except 26 & 29, they are zero)
103 Sat: 01 - 08: 00 76 84 00 19 65 N/A N/A
99 Sat: 01 - 08: 54 82 57 85 52 00 N/A N/A
On certain channels the picture is pixelated at best, missing at worse; the audio is out of sync at best and missing at worse. If my problems are signal strength related why doesn't the H20 choose the transponders with the highest signal strength ? If I only have one dish, why does the signal strength vary between tuners 1 & 2 ? For example, channel 249 is completely garbled, channel 840 good picture but no audio (it's XM, so what's the point).
I hooked up the Sony SAT-T60 reports "Searching for Satellite.." on those same channels. This weekend I'm going to compile a comprehensive list of all the channels that I'm having trouble with. I'm not sure how/why some channels are perfect and others are not.

I didn't know that... is there a channel/transponder list someplace ?bwaldron said:You should first understand that each channel is on a specific transponder on a specific satellite...there is no "choosing" of transponders other than selecting a channel.
Lyngsat will show you which channels are carried on which satellite but not which transponder. D* pressured the site to remove that info (which used to be there years ago). I guess they think it helps piracy to know which (fully encrypted) channel is carried on which transponder, though it seems pretty silly to me. Anyway, there are other sites that might have that info. Just google around and see.
Others have pointed you to Lyngsat, and have also noted that the info is less complete than previously.jdwatson said:I didn't know that... is there a channel/transponder list someplace ?
I don't yet have an HR20, so I may be wrong, but...if you tune to a channel and then so a signal strength test, it should start on the satellite/transponder of the tuned channel. At least it works that way on my receivers/DVRs...and is one way to know the sat & transponder assignment for a given channel.
I did forget that lyngsat changed. Sorry about that.
I'll have to try that with the SAT-T60. I find the UI on the H20-700 cumbersome to use still.bwaldron said:Others have pointed you to Lyngsat, and have also noted that the info is less complete than previously.

Does this imply that there's an aiming problem if some of the channels/transponders on the 101 satellite are giving me problem while others are not ? Or is it more likely that it's a hardware problem ?bwaldron said:You should first understand that each channel is on a specific transponder on a specific satellite...there is no "choosing" of transponders other than selecting a channel.
Some transponders on 101 are spot beams for local SD channels; you'll get low readings on some of them that are for areas near you, and 0 for others. Not a concern. If you're getting strong readings on most, your dish is pointed fine (at least for 101).jdwatson said:Does this imply that there's an aiming problem if some of the channels/transponders on the 101 satellite are giving me problem while others are not ?

I know from first hands - from Christian, the owner of LyngSat.com - he don't publish the information beause not too many ppl can contribute it; there are concerns about verification and updates, if one or two or three contributors will stop sending reports to him. Nothing else.LameLefty said:Lyngsat will show you which channels are carried on which satellite but not which transponder.

You posted pure hmm speculation ,not facts.:eek2:
The information is readily available elsewhere on the web. He should just get it and post it then.

jdwatson, Welcome to DBSTalk. 
Not that it matters much, but you keep referring to the H20. Do you have an H20 or "HR20"?

Also it's quite easy to tell what channel is on what transponder. Simply tune to the channel in question, say ESPN. Then go into the sat signal test are in the menu. It will default to the transponder of the station you are currently watching.
Now one thing to think about if there are several channels that are having issues is you could have a bad multiswitch. You can try removing it and go direct and see what happens.

Acording to LynSat, the San Francisco local HD channels are on the 103 sat, where I am geting the maximum reading of 100 on xponders 1 and 5. I have no problems with any of the local HD channels. In addition to the four main networks, we also get the local channel 4 in HD. So, 5 HD MPEG4 channels are transmitted in two of the sat 103 ransponders. I noticed that in your case, you have a signal strengh of 98 on xponders 2 and 8 in sat 99. You are also seeing lower readings on other transponders, but, in my case, the "non-used" transponders give me a reading of 0 (zero). Ineresting to notice that I am geting a reading of 95 on the west coast for transponder 2 on sat 99 while you are getting a reading of 98 for the same transponder, but on the east coast. I know that this is academic speculation, but I wonder just which transponders are really transmitting spot beams.
DirecTV does't make it public what transponders networks are assigned to. As you know already Christian Lyngsat will not publicize that information, although he does have the info. I email him a few months back, and he responded that he will not disclose that info.HDNut said:AT-0 in the San Francisco area.

Have a good day.
HR20, H20 don't specify specific tp's on signal strength, it gives all tp's signal levels at once, not individually. Older units do give specifics, but they can't see 99 or 103 Ka Satellites.bonscott87 said:Also it's quite easy to tell what channel is on what transponder.

I noticed that JDWatson has 0 signal on Transponder 27 for the 101 sat. I have 0 singal on transponder 28 for the 101 sat? Is this ok?
Okay the only spotbeam tp's for 101 are TP 4,12,18,20,26 and 28 all others are Conus meaning that you should be able to get a signal anywhere in the US on tp 27. So JDWatson should be getting a signal on tp 27. Tp28 is a spotbeam so I'm not sure if your network is assigned to that one or not, it could be that you need to get it. DirecTV doesn't make it public what individual networks are assigned to each tp, whether spotbeam or conus.Mixer said:I noticed that JDWatson has 0 signal on Transponder 27 for the 101 sat.
