multivision on dreambox??

abr 1

i have just installed 1.2 channel master dish to replace my 1 mtr dish.
to be honest there's not very much improvement at all.
but i have had to set the E&W limits and then adjust the sats again.
when checking 13 deg i found i could not get a good signal on multivision
about 46%
i have rescanned hotbird and tried to scan the transponder (11662 v 3/4 27500) but again very low signal and therefore it will not lock on.

using dreambox 7000s mgcamd 1.29.
i know that france 4 and 5 no longer AU.

i have a second receiver a samsung dsr 9500 i can receive multivision ok with this
i use a golden interstar twin lnb

anyone any ideas what i may try now??

What's the weather like? Is it just Multivision on 13E that has a poor signal? What is the SNR on MTV Two?

abr 1

thanks for the reply mhku

the weather is not bad really sun shining at the moment
on MTV TWO the snr 85% cyfra + obvious not picture as its seca

mhku

I get a higher SNR on Multivision than MTV2 (not that it helps you). Dreamboxes don't have the greatest tuners.

Are you using gotoXX or storing each sat position as you find and get a lock on them?

abr 1

using 18" actuator 36v seperate positioner msp200r

and yes i am storing the sats.

at the moment multivision is down on my samsung as well so obvious a key change,but that won't help me if i can't get good signal

mhku

Is the dish 100% correctly setup (zero position and the Clarke belt)? The Samsung may be more forgiving than the Dreambox.

Are you using Gemini? If you are there are settings for the LNB:

Menu > setup > service searching > satellite configuration

If you are using a 1.2m channel master with the correct feedhorn and a decent C120 LNB, the signal should be brilliant from your location. There must be something wrong with your setting up. Can you show us some pictures?

Hi Arthur,

M8 don't like to tell you how to suck eggs, you've been in this game long enough but something is not right with your dish setup.

Even with the poor performing db7000 with its dreadfully weak tuner you should still have more than enough with a CM120.

Putting seeing pictures to one side, what did the samsung give you in quality readings ?

You should be getting over 80% no probs.

Oh just thought, if you want to get you hands on a CM feedhorn let me know m8.

I had the same problem with Multivision and also with a few german channels on 19.2. The problem existed for ages until one day I unpluged the dect phone next to the DM500. They all work fine now.

michael01707

Yes, I have had this problem, always around the 11600s. For example ERT World, Bloomberg on Hotbird and True Movies etc on Eurobird 1. Changing to good quality cable such as Webro WF100 sorted this out for me.

I should note that the receiver was quite a distance away from the base unit of the phone.

well thanks to everyone who has posted

i installed the 1.2CM to replace the 1 mtr dish i had the signal quality is not a great deal better with the CM than my other dish

i am using the same lnb as before a twin golden interstar i have not changed the cable didn't see the need to.
i did the job yesterday so that it would not interfere with the football at the w/e
i have not got a feedhorn,(@keano may take you up on that offer m8 if i can get it sorted)
thought i would see what improvement if any i would see with changing dishes so no c120 lnb.
the samsung was showing multivision until it went down today,but the signal bar on the samsung shows a good signal it does not give a %reading

i do have some strong signals on 13deg 84% on some V and H transponders,just not multivision 11662/27500/3/4 this is 45/50%

the important thing is at least i do have good signals for the football on 19deg east and 1 deg west.

i think that the advice that the dish is not quite set up correct is probably true,and i will have to recheck this ,will do it now next week weather permitting

thanks to all

Get yourself the Channel Master feedhorn and a good quality C120 LNB, you will not achieve good results with a standard LNBF.

You will only get a very marginal increase in performance with a Channel Master feedhorn and a C120 LNB - for the vast majority of installations it is not worth the expense and bother. That is assuming you are using a decent LNB.

If you can't get multivision on dreambox look for another cause - follow up on some of the earlier suggestions.

@Burnham Beech

i am using a golden interstar twin lnb
i do have a smart titanium single lnb 0.2 but the signal was lower when i tried this.

i have checked all bolts this morning just to check they are all tight and have just checked Vertical channels on nilesat
(seems to be difficult to receive so i have read)
i get 73% on nilesat on these V channels

but not enough signal strength on multivision , but i know we will soon be losing this soon any way.

i do receive good signals for the football on 19deg E 1deg W.
and i'm sure now that the signal is better with the 1.2 CM than the 1 mtr dish it's replaced.

thanks

Sorry I disagree there, using the Channel Master matched feedhorn can make a big difference. However, there is certainly something else wrong with the set up, or perhaps as has been suggested, an outside influence affecting the signal.

Bear in mind that Multivision and most of the Hotbird channels can be received very well with a Sky minidish.

What is the MV FTA promo channel like?

abr 1

i get no picture on this and the signal strength is 46/50%

on the samsung which gets its signal from the same dish i get good signal on MV promo but at the moment AU is not working.
when the keys are available from m6 music black i get good pictures for a couple of minutes on multivision but this is on the samsung ,not the dreambox

Have you tried reflashing your 7000S?
Try the latest image 4.3.1

dago

hi m8, whats te signal quality on thor? as thats the highs sat, as long
as you are perfectly aligh, all other sats should be fine.
regards.

abr 1

thanks for the interest on thor the signal ranges from 75/85% bbc world 89%

keano

m8, I have just checked my db500 on MV and getting 85% and 76%AGC and not a single BER.
This is on a triax64cm dish.

Have you checked cable at the F connectors ?

Make sure no braid is in contact with the copper in the middle.

I think you should also look at replacing your db7000 or at least like mentioned try a new image.

Regarding the cm120 dish, you will see a big difference than the dish you replaced.
It just needs to be setup right.

Cheers

hi keano m8

using gemini 4.2 image (just in stalled gemini 4.3 in time for the match)

just watching liverpool v blackburn galaxie snr77%

waiting for man u to beat arsenal (are you going to the match??)

the picture is good so i will leave any further adjustment till in the week
could be interested in that feedhorn you mentioned though m8

arthur

keano

OK m8, so you have sorted it now ?

regarding feedhorn, I got it from another member called Snap of here and two days later I got another one from the USA which I ordered over 3weeks before and thought it would never come.

I also have a new inverto c120 if interested.

Not trying to flog you any gear but honestly to get the most out of your CM then it is a must you use the matched feedhorn.

abr 1

@keano

going to try to do final adjustments in the week weather permitting

i'm interested in the feedhorn.

but i need a twin output lnb
one to feed the dreambox the other to feed the samsung.

pm sent.

update.

i have tried to tweak the dish and have come to the conclusion that it must be the dreambox that is giving me a problem
i have connected my samsung to the dreambox using loop through and the samsung is able to pick up multivision with no problems and gives a good signal.
the two receivers are now side by side so both using the same dish same cable and same lnb

but seeing we are soon to loose multivision it not to much of a problem
thanks to all those who tried to help
