How to set C & KU band in dreambox 500S i am unable to scan C dand transponder

 

[member91040]

Put the Frq 5150. Bro

 

[batpower]

where to put this 5150 ?

You dident got your manual with ur Box bro. Try this

I have tried what is suggested above. Also, the following:
et the LO frequency for the corresponding lnb to 5150MHz

You may need to tag the "INV" option if you try to do a manual transponder scan.

My DM500S is a bit tricky to get going on C-band, perhaps since IF frequency is calculated inversely (LO is higher than received frequency).



This next trick will ALWAYS work however since all sat receivers actually receive 950MHZ - 2150MHz, the rest is software and math to display and use actual frequencies:

If circular polarisation is used you can translate like this:
Vertical = Left hand circular polarisation (LHCP)
Horizontal = Right hand circular polarisation (RHCP)

Now translate the C-band frequency into a Ku-band frequency like this:
5150 - Cband_MHz = IF_MHz
IF_MHz + 9750 = Ku_lowband_MHz or IF_MHz + 10600 = Ku_highband_MHz

Note that the higher the C-band frequency is, the lower the fake Ku-band frequency will be.

A few examples for you to try out on Insat 83.0 deg East:

Asianet mux 3643V
5150-3643 = 1507
1507 + 9750 = 11257
use 11257MHz Vertical

Kairali 3845V
5150-3845 = 1305
1305+9750 = 11055
use 11055MHz Vertical

For both above examples the receiver must be configured to have a Universal Ku-band LNB with 9750/10600MHz LO.

Good luck

Edit: You can use any satellite you don't need in the satellite list as Insat 83E and scan manually. It will then serve as a placeholder for the channels you have actually scanned on 83E.

I get some of the C band transponders on 68.5 but not all - I cannot get Geo and Multichoice but get B4U, Dawn, ARY .....

Can anybody help?

5150 is a L.O of LNB (local oscillator) that setting from C-band frequency

 

[syedamerali]

You seem to be receiving the horizontal channels and not the vertical. This probably means that you have a twin frequency LNB i.e. 5150 and 5750.
For Geo broadcasting at 3799 do the following.
3799-600=3199 where 600 is the difference between 5150 and 5750. Put the frequency 3199 all other parameters including symbol rate and FEC to be the same and tune the transponder manually.
Should work ... keep us informed

I sincerely Thank member91040 who helped me get Dreambox from phuketsatellite/eldsat*com.So far I am unable to set DD DTH although Nss-6
is setup successfully.

I recently bought Dreambox 7025 and trying to configure the dishes. I am not able to configure Intelsat 7/10 (C-Band) on my Dreambox 7025.

Let me tell you my configuration in detail before:

I have following dishes:

1. Badr 26.0E (Universal LN
2. Intelsat 7/10 68.5E (2 C-Band LNB: 1 for Horizontal & 1 for Vertical)
3. Hotbird 13.0E (Universal LN
4. Nilesat 101 7.0W (Universal-LN

in following setup:

1.  Badr 26.0E (Universal LNB) -------------------------------------------------------------------> DiSEqC Input 1 +---------------+
|               |
2a. Intelsat 7/10 68.5E (Horizontal C-Band LNB) ---> LNB Input 1 +-----------+                                     |               |
| X Switch* | Compined Output ---> DiSEqC Input 2 |               |
2b. Intelsat 7/10 68.5E (Vertical C-Band LNB) -----> LNB Input 2 +-----------+                                     | DiSEqC Switch | --> Output to Dreambox 7025
|               |
3.  Hotbird 13.0E (Universal LNB) ----------------------------------------------------------------> DiSEqC Input 3 |               |
|               |
4.  Nilesat 101 7.0W (Universal-LNB) -------------------------------------------------------------> DiSEqC Input 4 +---------------+

* - X Switch is some switch used for combining Horizontal and Vertical LNB signals.

The thing is, I have the remaining dishes setup in my DB7025 but only have problems with Intelsat 7/10.

I have tried setting Intelsat 7/10 to C-Band in the LNB Settings and also tried User Defined and manually entering 5150 for Low and High. Moreover, I have tried the User Defined and entering 9750 Low and 10600 for High and conversion setting for following Frequency and in following calculation:

From _http://www.satcodx3.com/0686/eng/
HUM TV: 3.774 GHz Horizontal 3300 Symbol Rate

5150 - 3774 = 1376
1376 + 9750 = 11126

Then entering the Fake HUM TV Frequency: 11.126 GHz Horizontal 3300 Symbol Rate, still does not pick any channel.

All of the above mentioned methods do not work.

However, if I connect my old receiver I am able to tune and watch channels for Intelsat 7/10. So, the X Switch in the diagram above does not have any problem.

Let me know if I am missing something here or what else I can try.

Thanks in advance.

hi guys,

i have Intelsat 7/10 its working fine some of channels r missing but its ok i have only one problem im using paid CCCam server i can scan all channels free to air working fine but GEO news and any other channels which is paid r not working, can u guys put some light on this issue Thankx....

 

[srei]

There are problems/issues in setting Dreambox paricularly for satellite Intelsat 7/10@68.5E.
My old coship receiver shows all receivable channels but Dreambox shows dreams...for some channels.

 

[cyprassb]

i have a 180cm dish and i was using it to watch channels on a ku-band all free to air .i then changed the lnb to a c-band im only watching few channels like,cctv 9,e,f,4,b4u music,b4u movies,aljezira news,ewtn,ptv,humtv,royal tv,india tv, rohi tv, view asia, kbc, dm islam only. there are a lot of channels like God tv asia , suprime master tv, qtv,the musik ,all the DD channels , the Geo channels and others are saying no signal.i tried to reset the dish and even twist and turn the lnb but they can show.help me please

 

[batpower]

last month i bought a Swedish made diseqc switch which costed me 120US$ but it was the only Switch that gave me strong signal for both H/V channels on all of my 4 Satellites Hotbird/Intelsat902/Nilesat/Badr . the Brand name oif the switch was something like Starsat i guess . so i think the quality of the DiseqC matters and effects DM alot .

Hello!
i dont know what dish size do you have and what the signal strenth of dd india is in your region, not every transmoponder has the same footprint,some are stronger nhk view asia on intelsat 7 mtv india transponder for e.g

but the music transponder is much weaker,and dordarshan india,is one of the weakest,i have only signal in the night,on daytime its gone!

maybe only multchoice transponder,are realy strong in africa,and others also weak i dont know,i can only report here from europe!
try to readjust your dish,and checking,the scew angel,of the lnb,this is very importend,to get signal on the weakest transponder,and needs a lot of time to fine adjust,good luck!

 

[Myhd]

I have 180cm dish, using C band on 68.5E. Most channels including MultiChoice on Intelsat 7/10 have SNR of >80%. NHK is strongest at 87%.

 

[onlyamir007]

Myhd All ur paid channels r working on 80%????

 

[Turok]

yes,nhk is very strong because the sending with fec 1/2

if you take a look at the freqency list,you will see that most of the freqencys used both polarisation,with difrent simbolrates,this takes you a lot of the signal quality of the weaker channels,
multichoice here very weak,i got all channels,but not much signal reserve
the weakest is 3836 3863,and 37616 is much stronger then 3836,and 3744,is weaker with mtv and espn on it!
i hope,that the satelite,soon will be replaced!
last night,dordarshan india,was very strong picture with out interrption,todays ago it was complitly one or full of artecacts,if you want constant signal also on ujala tv you need here 3,60m mesh..!

you have signal in your region on ujala tv?
in spring this year works great with my 2,40 m mesh dish,and i watched often,there were many docementarys,from germany,from the 80`S that are very old,was in german lanuage syncroneized in enlish,very funy for me to watch,this channel is gone now,K2 tv,the indian music channel curencly with test transmision is also weaker here !
hope that the new satelite when it comes,in around 2 years,dont not have,this kind of new cband spotbeams,that whould,mean,that we can say good by to the most of the channels,on this bird !

for exact optimeizing your signal,please take a look on ww++.satlex.de

type in your cordinates,

then you see a digagramm,of the exact elevation,and also a diagramm,where show you the exact scew angel,you need,for your location!

 

[Myhd]

onlyamir007, yes and after slight tuning, confirmed paid channels at 85%, NHK at 91%, Ujala TV only at 72%.

 

[Turok]

hello,somtimes,there also some i ndian feeds,that are so low,in signal strenth,that here 3,60 m mesh is needed ,you receive them also ?

 

[onlyamir007]

hi dear "MYHD" thanks for ur reply can u tell me how did u do that coz, im trying 2 do but no luck C band LOF/L = 05150 LOF/H = 10750 & i also tried LOF/H = 57500 threshhold = 11700

i don't know what to do .....
