No signal quality.

[demigawd]

Hello everyone been a member for years but I don't think I have ever posted anything, until now. I think I need some help, I pulled out my old Sonicview HD8000 to see if there was anything that I could do with it but I seem to be having trouble picking up the satellites. I have an excellent signal but Q is 0 on all transponders. I have an old 8PSK board from a DN 6000U which worked fine in the past, are those still the correct 8PSK modules? The ones I see on Ebay are considerably different than the one I have. I have a DP+ 3 LNB dish and I used the most recent channel list I could find and S is 90+ but I can't seem to get Q to move from 0.

If anyone can give me some insight I would greatly appreciate the help.

I'll also try to keep the dumb questions to a minimum.

You need to install a turbo 8psk module & edit the transponder list.the 8psk from the ird won't work for you.

[demigawd]

I thought that might be the case. I will try to order one. Thanks for your help.

Are there any QPSK transponders I can try to make sure everything else is working before I spend the money on the new board.

[The Noof]

There is a reliable vendor on ebay of sv parts & services.I believe his user name there is danmarco.You can try to see if you can get channel 9421 (velocity).From here I'm not sure of the modulation, but it is a free channel.Search this site or go to lyngsat for modulation info.

[demigawd]

Ok I said I would keep the dumb questions to a minimum and I hope this is my only one.
Is there a difference between these modules. I have found 2 of them one is a red board 8psk mpeg-4 module seller says it contains 2018 updates and then there is a green one that says A-1 rev1.1 BIN #B0. Would either of these be the correct one?

EDIT : The seller you mentioned is the one with the red board so I will grab one of them. Thank you for all your help.

red board ...

Last 6 or so on 110 or first 5 on 119 and you should be able to find something still QPSK with in some of the spotbeams. Listing on site here post #15 toward the bottom of the post:
https://www.satfix.to/showthread.php?191165-Transponder-Updates-Changes-Lists and or on jameslong/lyngsat. If you are still needing one. If you have used a resent list then the conus tp's should be up to date. Symbol rates changed around 2015.

[demigawd]

Well I have an update. I ordered the new board and got it installed, unfortunately I still can not get anything to work. When I go to dish settings I can see there is plenty of signal ( S is around 90) but Q stays at 0. I have turned on the external module and gone through the TP list and set them as listed but still nothing.

Could I have a firmware problem? Is there a recommended file to use?

Again thanks for any help you can offer.

EDIT : It also seems that no matter what diseq setting I use the signal doesn't seem to change. Could the problem be my dish. This dish came with the house so I am not sure exactly what it is other than a DPP 1000; are those compatible with the 8000HD?

[vapor]

Guess it is possible your dish in out of alignment. Could go to

http://www.dishpointer.com











and check your elevation and skew etc. Just put in your address and your dish type. I will say this from recent experience you may need to add close to three degrees to the elevation and skew to get good strong Q&S. The more info you can provide in regard to your dish the better the help.

Files are important in the end but most will work the same with Q&S and scanning for the most part. Have seen some older files show a certain epg that newer ones won't but as it stands now with that particular bird it's worthless. All that being said you will need a certain file in the end network and version wise so you may as well have the correct one loaded from jump. There is a nochk file posted that works with either iHub/wiz110sr/4.12.

Those DPP 1000 are a real pain to setup, have built in switches,etc.
A Dish 500 with legacy LNB'S is alot easier to setup.

Actually the OP could have kept the original DN 8PSK board as it it Turbo 8PSK. But that board is a power hog so the new red board is much better anyway.

The reason you get no Quality is that all the transponders (TP's) are no longer DVB, they all have to be changed to Turbo 8PSK.

old = DVB, SR 20000, FEC 7/8

new = Turbo 8PSK, SR 21500, FEC 2/3

Change all your TP's or just a few and see if you get quality. Make sure your switch and LNB are set to what you have now.

Might be a channel list in the file section with updated TP's use it and then set up LNB and switch and you should be good to go.

s at 90 means it's reading lnb
q at 90 is what you want

A dishpro is set like this

LNB type = OSC-DP
LNB frequency = 11250
Sat 119 = diseqc 1
Sat 110 = diseqc 2
Sat 129 = diseqc 3

I think This might be my problem. I have the wrong type of LNB selected. I have never used one of these 1000 dishes before, my old house I had put up a motorized dish with a universal LNB.

I will try changing the dish settings to these and cross my fingers.

Thanks everyone

Something else you may want to run your cabling down and see if there is external switch in line. If there is that could be causing a problem. Guess it is possible there's a 44 or 34 in the mix. Just a thought.

1000.2 manual that maybe of help and or just in case. Angle tables starting on pg.10:
https://manuals.solidsignal.com/151255_01_text.pdf

Just keep in mind some of the info in the manual may not work the same or as well with an stb. Some could possibly cause damage to an stb as well

The SV8000 is under powered to run a DPP1000 LNB, you need at least 750 mA of DC current to get that LNB to run right, most FTA receivers can only supply 500 mA of DC current, your problems could be lack of DC current to run the LNB.

The only things that will run that LNB correctly are an OEM receiver from Dish or Bell and a DP44 power inserter from a DPP44 switch.

The speck's on that LNB are DC voltage input 20 volts DC, at 750 mA to run right.

Also to see if the dish is aligned correctly use satellite 119W and TP 12414L on channel 101, this is an open channel, then check 129W TP 12516R on channel 9599, this will give you the message "You have a dish on 129W".

If you see these channels then the dish is aligned correctly.

Also this LNB uses band stacking, this gets all the transponders down one coax, thus the OCS-DP for the LNB type, it also needs coax rated at 2.5 GHz or swept to 3 GHz or you will be missing a ton of transponders.

This LNB has an internal Diseqc switch so there should be no external switch in the way, unless there was a need for more then 3 receivers in the original install, the a DPP44 switch(or more) would be used.

[demigawd]

Success!

It all came down to setting the correct LNB type for the DPP 1000.2, also had to tweak the dish a little bit to get it peaked but I am now able to get CH 101 in. Now I just need to find a good IKS provider.

Thank you for all your help everyone

[demigawd]

Well, I may have spoken too soon. With the recommended firmware file, updated tp list and a fresh channel scan I seem to have large blocks of channels that are just black, no nag messages just black, but some channels from the same transponder as the channels with no video work great.

I'm not sure how much detail to put on here with out breaking rules.

Anyone willing to take a shot at my new issue?

[Terryl]

You may have bigger problems if you don't use a DPP 44 switch power inserter to run that LNB correctly.

You don't need the switch, just the DC power inserter for the switch, unless your receiver can supply 750 mA at 20 volts DC for a long time then you may burn something out in the receivers DC power supply to the LNB.

Check on the back of the receiver to see what the DC current output is labeled where the LNB coax attaches to the receiver, if it says 500 mA MAX, then you may be having DC power problems with that LNB.

I'm sorry I thought I had said I had a DP44 power inserter inline on port 1, but I may have forgotten that above, I also have the receiver on port 2.

I am getting most channels in fine but there might be 5 out of 20 on a transponder that work, and the problem seems to span a few different transponders but not all, nor are they all one polarity. Its an odd problem because its not happening to all transponders or to all channels on any one transponder.

So I really don't know where to start. I have started over and reset all the satellites and re-scanned all the channels but the same ones seem to give me problems every time.

[Terryl]

OK, now that we got that out of the way.

You say the dish came with the house.....Do you now how old the dish and LNB are??? It could be a bad LNB, if you can, move the receiver connection to the #3 port on the LNB.

It could also be a bad/corroded connector or a split in the coax that has let water into the coax, this would cause all sorts of problems, I have seen problems with water getting into systems that cause strange problems at the receiver.

One quick test of the LNB and coax is to run a temporary new coax out to the #3 port and connect directly to the receiver, if you do this be sure the coax is rated for 2.5 to 3 GHz, and not for CATV.

This would bypass the old coax wiring in the house and tell you if it is good or not.

The D1000 type LNB's run at some very high frequency's, and some of the channels may be affected by a bad connection or coax, you may have a decent "S" signal but you have no idea as to what is really going on with the IF signals coming down from the LNB, you would need a spectrum analyzer to test this

The signals coming down from the satellite transponders are at 12 GHz, these signals are way too high in frequency for normal RG-6 coax, so the LNB down converts them to something that can be transmitted down normal coax, this is the 11250 setting, this is the Local Oscillator frequency, this is mixed with the transponder frequency to give you an IF frequency.

Now the channels are not all lined up in numerical order but scrambled around between different transponders, a problem in the coax or a bad connector could cause a lower then normal signal on that channel, and your receiver's AGC is just blanking it out.

Opps sorry too much coffee this morning, I'm rambling again.

[demigawd]

I'm not sure how old the dish and stuff are, we have lived here for 4 years and it was here when I moved in, so I'll admit the cables may be the issue. I have a bunch of RG-6 I'll try running a line out and see if the old coax is bad.

But now my question is if it's an RF issue wouldn't that affect all the channels on the transponder? If I scan in one just one of the transponders giving me problems I may have 4 or 5 out of lets say 20 channels that I can actually watch while the others are just blacked out. These are basic channels that I'm sure should be available but for some reason I can't get them to work.

Anyway I will try a new run of coax and cross my fingers, what do I have to lose.

Thanks again.

There are a lot of things that could cause such a thing to happen. That being said even if things are clicking as they should be stb wise it still could happen. You could have 20 showing but for what ever reason only 6 are up. You can only get what is coming to ya. Example...you scan in 40 on a certain tp. 15 are mirrors and for what ever reason 12 are black for the time being. That only leaves 13 up.

[Terryl]

Well you not going to get any of the spot-beam transponders,(local channels) but only the CONUS transponders, and Vapor that list looks quite old.

On sat 119W the CONUS transponders are 6, 7, 8, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 and 21.

Here is a list of packages (channels on that transponder) for 119.

https://www.lyngsat.com/packages/Dish-USA-119W.html

As you can see WABC is now on channel 4042, and is only an SD channel, the HD channel for WABC is now on 61.5W TP 12530 (spot beam #2) channel 6300.
Package list for 61.5W
https://www.lyngsat.com/packages/Dish-USA-61W.html

They have been playing transponder hockey over the years, so things have changed drastically.

Even the listings on Lynsat can't keep up with the changes, so this info could also be off.

[vapor]

They were current.

[Gates07]

doesn't he need a power inserter so he does not burn up his p/s?

[vapor]

Think that was covered in a few posts so far.

[The Noof]

yes, he does need external lnb power for this reason
