    Default setting up Satellite C and Ku band

    Hi,
    I just bought used set of receiver with 2 dishes (2.3m and small one). The receiver is Strong 4260x using Dual Pol LNBF for the small dish. I am trying to get the signal of any satellite (bird) but so far no luck at all. I have used rf10700, 11300 and same rf as written on lnbf (12250-12750). I did change the lnb to Universal LNB and I set LNB type as universal but still not working. I changed the receiver to Daewoo DSD 9521M and did the same thing as above but come out with the same result, the bar for level is good 90% but the quality bar never goes up even when I tried both dishes.
    my understanding the lnb skew does not stop us from getting the signal, its might just effect the quality. the connection between receiver and LNB is good as when I disconnect the cable the level signal goes down.
    I have used dishpointer.com setting and direction to find the satellite direction. the satellite I tried to get are Optus D1, C1, Asiasat 3s and Apstar 6.
    I have tried all things in my head and from what I have read in other posts in this website, but no luck so far.
    As I am moving to other house in the next month or two I would not like to call a professional to fix it.
    Any idea what is missing? or things I have not tried?
    thanks in advance.

    G'Day Cobber,
    Let's take one thing at a time.
    Unless the dish is motorised, you can only normally get one Satellite at a time.
    If this is written on the LNB
    (12250-12750), it would suggest that it is an 11300 Local Oscillator LNB, so that is what you need to use in your dish setup. It should also have 11300 written on it.
    The easiest Satellite to find is C1, D3 is also co-located at the same position, but you need an 10700 LNB to get them both.

    DishPointer will give you Azimuth(relative to True North) from your location.
    It will give you a ground line of sight to the Satellite. Stick with C1 'til you get the hang of things.
    It makes things easier to adjust if your mast is plumb, vertical in all directions.
    You also need to have the correct Elevation, this is set on the Mast Bracket, with Latitude on one side or Elevation on the other. Use Either.
    Once you have that set up, as well as the correct details in the STB installation menu, on an active Transponder, you can slowly move your dish Up/Down and L/R until you get a Lock in the Green. Then you can tweek all settings for maximum signal Quality. ie: azimuth, elevation and Skew( The twist of the LNB in the Bracket).

    See how you go there and let us know.
    Kindest Regards, " The Druid ".

    Thank you beer4life,
    you are suggesting to use the smaller dish with dual pol LNB, I will try it, how about it the big dish with C band? can it be used for C1?

    You can use the C-Band dish for Ku but you want to use it for both C and Ku signals so you'll need a combined C/Ku lnb. The problem is the Optus sats have a different LNB skew angle to all other sats so if you peak it for the Optus sats you'll have problems getting all the others. I'd suggest using your small KU dish for Optus sats and the C Band dish for everything else. You can then connect them together using a diseqc switch to your receiver but we'll save that for another lesson!

    Good Morning Weley, I also live in Adelaide,Modbury North.I have six satellite dishes going in my backyard--3 metre --2.3 metre ( c band and motorised ).Also four ku band dishes,one has four lnb's on it( c1/d3--d2--d1 and intelsat 8 ).One for intelsat 701(1.2 metre) and another one for nss6 (small dish). A 65 cm dish for c1/d3 separate from the others. I use two strong receiver boxes and two DiSEqC switches to combine all together.Where do you live in Adelaide because i do not mind helping you out as i have for many people. I do not charge because i see it as a hobby, and your willing to learn. Please contact me and we will go from there. frachwal.

    Thank you frachwal, actually I am living in the south of adelaide (morphett vale), I will try to fix it myself but I will need your help when I want to motorized my c band dish. It has the motor and ready to use, it just I am want get one bird first so hope this will motivate me do more.

    I suggest, setup the Small Dish First, for Ku band,

    Maybe on optus C1/D3 (you will need a 10700 Lo LNB)

    or Optus D1 you will only need a 11300 Lo LNB

    You may find it easier to pickup a Satellite finder on ebay (usually less than $20) to help you find the Sats

    Good Luck

    No a 10700 LNB is not a Universal LNB,

    How do you know you have a Ku Universal LNB ?

    The Universal will work but require different settings

    G'Day Cobber,
    You could use that Universal, but need to have this in your Dish Installation menu.
    LNB: Universal

    09750
    10600
    11700

    Try that.

    Just wanted to add - being that I'm a satellite virgin, this is all very interesting reading. So thanks to those that are contributing as it's helping inform me and prob a bunch of other sat newbies also

    Hi friends,
    regarding the elecation angle for optus C1 should be 45 as per dishpointer website.
    I see on both side of the dish mounting got scales AND in both of them the 0 degree does not match with the pipe that I am fixing the dish on. if I darw a line from the 0 that show on the dish mounting its not parallel to the pipe. so when I put my dish on 45 degree as per the scale on the mouthing is it correct 45? or I am away for it?
    2nd Q: the part I connect the LNB to is lose, I did soldering back. however, can I use the LOOP as alternative to LNB in?
    Thanks

    You can only get the Dish angles as good as you can, (& you may or may not get pictures straight away)

    LNB skew is about 7.30pm, looking at the cable out, looking into the dish, for Optus C1/D3

    Connect the LNB to the Sat finder (if you have one) then to the STB, then cables to the TV

    It is best, if you can have the TV close to the dish, so, as you slowly move the dish from east to west, & up & down you can watch the Quality bars from the STB on your TV

    Quality bars, & the Level Bars, turn green on a Strong STB when you are on a working transponder on a Satellite

    Setup your LNB settings, i.e. in the Strong, maybe like this:

    Satellite: Optus C1/D3
    LNB Power: ON
    LNB Type: Universal
    LNB Freq: 9750/10600
    22KHz: Auto
    DiSEqC Switch: OFF


    Then Set Your STB (in Manual scan) to a known Working Frequency on Optus C1 e.g the INFO 156 channel is:

    Satelite: Optus C1/D3
    Frequency: 12407 GHz
    Symbol Rate: 30000 MS/s
    Polarization: Vertical
    Search type: All Channel
    Network Search: ON

    You should not have to move the dish much if your angles are close,

    When you get green bars, fine tune everything to maximum Signal & Quality,

    Tighten up your dish

    Then hit OK to do a manual scan on that transponder (at the end should get a few channels)

    Then do a blind scan from the Strong Installation Menu

    or input all the frequencies from lyngsat.cam


    P.S. That spinning LNB input, on your STB does not sound good, but I do have a space STB that does the same thing, & it will work ok though the loop connector, someone here might say if it is safe to use or not....

    G'Day Cobber,
    The reason for your confusion over Dish Elevation is because the LNB is offset from the centre line of the dish.
    The offset varies on different dishes, but is around 27 Degrees.
    Do what I said earlier and set your Elevation or Latitude according to the markings on the Dish Bracket.
    This illustration should help clarify the seeming anomaly that you have noticed.
