Signal Strength Review Please

906 Views 6 Replies 4 Participants Last post by  rokclimbertx
Curious about my signal strength and hope one of you more knowledgeable guys can give me some input...

I moved the location of my dish (5LNB, slimline), tuned as best I could and have noticed a split second of searching for signal when changing to an HD channel... Not every time but enough to make me question it... Called Dtv & a Tech said that I should be concerned with 103a transponders 1-6 being so low and scheduled a for someone to come out in a couple of weeks...

Location is 76240, Cooke Co. Texas (65 miles n. of Dallas)
Readings are from an H20-100, 0x407A
My newest box, an HR21-700 I believe, has similar readings but is recording and I can't double check... WB68 multi-switch in use as well and the HD DVR has BBCs connected that check out on 480-1...

Thanks for looking over my numbers and any advice you might have...

103a are spotbeams so several transponders might be low or 0s.
The rest looks all good. 119 looks lowish though.
The tech was giving you bad advice. The 99b and 103a screens only show spotbeams delivering HD locals and so it is perfectly normal to get zero or low signals, as Mertzen says. The 99a and 103b screens show the transponders delivering national HD channels and those signals are all fine.
Do you have something blocking the line of sight to the 110 and 119 satellites (trees??) because all those signals are low. You don't need programming from 110/119 but the guide updates come from 119 when you are watching a 103 channel so you might see a loss of guide data from time to time.

Just FYI here in DFW my signals on 99b and 103a are:
99 b
0-0-64-82-0-72-n-n
n-n-n-n-n-n-0-0
89-97-0-0-95-95-23-0
n-n-n-n-n-n-n-n

103 a
0-0-0-34-0-24-n-n
n-n-n-n-n-n-91-93
0-0--95-80-100-0-98-96
n-n-n-n-n-n-n-n

The DFW HD locals come from 103a TPs 21 and 23.
The differences between our signals is because I am closer to some spotbeams delivering HD locals to other cities than you are, and you are closer to some than I am. But you can see our signals are very similar.

That said, if you are getting 771 searching for signal messages when you change channels that looks like a "slow" tuner. You are seeing 771s, correct? Not "no signal" messages from the TV? because those are nothing to do with DireCTV signals, they are caused by your TV losing the signal from the receiver over the HDMI cable when you change stations. You can usually solve that one by setting native "off" instead of "on" on the DirecTV receiver.

As far as trees... The new location is much better than the original one... I'd say line of sight is excellent...

I'm not getting the 771 error just a second of the searching for signal bars then it seems to lock in and picture comes up... And this was in the upper 200's (History, NatGeo area)... These would be 103b right?

Looks like a bit of tweaking is in order to bring 99b and 103a up... We used 101 to tune the dish in... I'll use 103a this time and try to even it up...

Thanks so far!

Every service call I've been on where it was the split second 771s, it ended up being a connector issue. Either a loose, recessed, or corroded connector somewhere in line. Check all of your connectors, make sure the white dielectric center is flush with the inner edge of the cable fitting, no water is getting in (dielectric will be rust colored instead of white), and they're all on tight.

You don't really need to do anything, your 99/103 signals are fine. The only 103a signals that matter are TP21 and TP23, those are only two points lower than mine and I am in the center of the spotbeam, all the other ones are for other cities not for you. If you really want to spend the time then you can fine tune the dish so that your 99a and 103b signals are a few points higher, then 103a will automatically improve. You don't need to align on 103a. But there's really no point in trying to adjust your dish any further.
If you do decide to adjust your dish I would be more concerned about your 110/119 signals. As I said, you don't have any programming from those sats but if there is no line of sight issue then your low signals seem to show the tilt is not set correctly, or the dish is not plumb. That might cause problems getting guide data from 119.
There may be a cable fitting issue, I had to replace an end and didn't have an RG6 handy so I used an RG59 end... I think that entire cable needs replacing in any case...

I'll concentrate on the 110/119 signals instead then and double check the plumbness of the post, it very well could be a shade off...
