Diagnosis reqd: SD pq 70% vs HD pq 5%?

slicedpanman

I'm having problems on my motorised setup pulling in HD channels and need some advice/help...

I'm in Limerick with a 80cm dish and an inverto black ultra eco lnb connected to an Edision Argus mini 2-in-1 ip box. Here are some of the quality stats from 3 sat positions;

13e 11278V 27500 3/4 dvb-s2 8psk - 40%->50%->60%->40%->50%->60%->etc.
13e 11393V 27500 5/6 dvb-s qpsk - solid 70%
13e 11411H 27500 5/6 dvb-s2 8psk - 5%
13e 11488H 27500 5/6 dvb-s qpsk - solid 70%


5w 11055V 29949 7/8 dvb-s qpsk - solid 70%
5w 11096V 29949 3/4 dvb-s2 8psk - 50%->60%->70%->50%->60%->70%->etc.
5w 11470V 29949 3/4 dvb-s2 8psk - 30%->40%->50%->30%->40%->50%->etc.
5w 11679V 29949 7/8 dvb-s qpsk - solid 70%
5w 12522V 29949 2/3 dvb-s2 8psk - 10%->20%->30%->10%->20%->30%->etc.
5w 12690V 27500 3/4 dvb-s qpsk - solid 70%


28e 10773H 22000 5/6 dvb-s qpsk - solid 75%
28e 10847V 22000 2/3 dvb-s2 8psk - 5%
28e 10862H 22000 5/6 dvb-s qpsk - solid 75%
28e 10936V 22000 2/3 dvb-s2 8psk - 5%
28e 11224V 27500 2/3 dvb-s qpsk - solid 70%
28e 11585H 27500 3/4 dvb-s2 8psk - 5%
28e 11681V 29500 2/3 dvb-s qpsk - solid 75%
28e 11720H 29500 3/4 dvb-s2 8psk - 75%

I've no problems getting a good quality percentage on any SD transponder but the HD ones are very hit and miss for no obvious, to me, reason. From the stats you can see that most HD tps show nothing, the very odd on is ok and some are on the edge... moving up and down constantly in the quality figures

Anyone have an idea what might be causing this? Dodgy lnb? Dish too small? Or is this a symptom of pool alignment?

i have checked a few of those for you, I have the argus mini 2 in 1 and I have it on a 68cm dish in clare, for 28east using an inverto octo lnb. I get 84q bbc hd and 76q itv hd so it means your set up is slighhtly off. 80cm should be very strong.

Did you tune in the lnb, ie move in and out and a slight twist. Or to make your system even better what satellite did you set it up on? I used 8west, peak that etc.

I used to have the edision hooked via switch to a motorised triax 1.1m as well but I am swopping out the edison today for a vu+ uno.

you need to check cables etc, whats the motor and are you using usals? and what is the make of dish?

i had a look at that lnb you are using and its cheap but it looks as if you cant do much adjustment with it, looks like an lnb for a sky dish. the one you need is this one

INVERTO Single L.N.B.__INVERTO BLACK ULTRA HIGH GAIN SINGLE LNB, its dearer but worth it and it has the long neck. I use a quad one and its the best and I have quite a few other types.

also good cable. I use a dark motor with a spiderbox, triax 1.1m and the black ultra. I get 42east to 30w no problem.

Change symbol rates on 28 10936 23000 that one is a very strong 19.2 dB with me. 11585 is 29500 and you shouldn't be getting anything on 11681 with 29500 it is 27500, maybe a typo? All of the Hotbird and 5W tp's are very strong with me.

I wonder could it be the software version you have? I ask because in this old thread I see the following posted on page 20.

http://www.boards.ie/vbulletin/showthread.php?t=2055792912

There is SD and also HD software. Do I need to install both or will it just accept one?


You could compare software versions with GBCullen?

swoofer

just a quick update, my dish is 78cm and not 68cm so your figures should be in the 80's as well.

I dont use the official firmware.

11720H is actually DVB-S2 QPSK. (So is 11585 but you have the wrong SR there.) Your problem TPs would seem to be 8PSK, so your dish probably just isn't aligned well enough to deliver the signal quality necessary to successfully demodulate 8PSK.

Thanks for the replies guys... I ruled out the cable as I used a very short and good cable out at the dish with the same results. And yes I'm using usals and set it up pointing at 5w.

I've attached an image of my dish setup. The dishes are identical and the one on top is fixed on 28e. I've a humax foxsat connected to that one and that's reporting 100% quality on BBC one HD whereas the motorised one below (pointing at 28e in the pic) is reporting 5%!

I expect that I must have made a pigs ear of the initial alignment... Just confused by the fact that SD channels are good and the 8psk one are knackered

Change the symbol rate on 10847 V on 28 to 23000 as per Lyngsat and see what happens. That is the frequency of BBC Northern Ireland HD.

out of interest have you just set this up?

Nope... It's up about a year but not sure it's ever been quite right.
I expect there are a few typos in the frequencies, symbol rates, etc but it was just to give you an idea.
I'll take a look at that link about the firmware - I'm also using nonstandard firmware so if I'm lucky its a bug related to 8psk tps... If not I'll need to get back on the ladder and start again

swoofer

that looks ok of apart from the sloping roof. i could send you a copy of the firmware i am using as we know that works. i would tweak lnb and dish alignment as well but it could be
software related. have you any spare lnb as well..

its a problem i have never seen

Cheers... do please pm me the firmware you are using. I had already tried adjusting the lnb - in and out from the dish (good range of movement on this lnb) and the skew. The figures above are the best I could get after doing this adjustment.

I also have an old (maybe 10+ years) spare lnb and tried that too but got the exact same results.

What I was also thinking of trying was moving the dish to 28e and then swapping out the Edision and in the Humax foxsat to see what figures that gives me.

And I'll also try your firmware too...
thanks,
spm

swoofer

it might be an idea to swop boxes and that would rule out lnb, box may be kaput as well.

here is a link for newer software, I use kuniberts hd version. mine is jul 2011 but it works so try that first.

http://www.boards.ie/vbulletin/showthread.php?t=2057037219

NB when you do an update sometimes box defaults to hdmi ie no pic with scart. I use component as well as scart and hdmi so I always have access.

this is the file you need, change the extension to .abs. Its got everything, channel list etc.

the file has an emu facility but my mini does not have ethernet port. its hd so menus look good. its version 1.3.193.

go slow and if unsure just ask. NB I checked my box and I have the settings at hdmi. If you dont have hdmi then dont update. I can change it to scart and re-send if you need it.

That roof won't be causing problems for any of the satellites mentioned in the OP. There's no way you can tell how well the dish was set up from a photo like that.

STB

One of those 13E's is Cyfra +HD Channels.

You need to skew the LNB.

swoofer

he's motorised so skew would be automatic.

rurs

I had similar problems with the 11411H TP on 13E, your initial setup is fractionally out.

In my case, I had no trouble with 28e, but the 13e HD tps were very hit and miss...more miss than hit. I would suggest peaking the dish on 11411H, and see how that affects the rest of your arc.

slicedpanman

oh you beauty! Cheers GBCULLEN

That firmware did the trick!!! woo-hoo... pulling in the nSport HD and the HD channels on 11411 now - got nothing on these before

I'd say alignment could still be better but the correct firmware has certainly made a huge improvement

Thanks again to all... especially gbc!
now can't wait for my new cyfra card from satsklep
