    Default Unaohm AP 301 HD - VAST Viewing

    Hi All,

    I am currently using a Unaohm AP301 HD to tune a dish to the VAST sat - Optus C1.

    I am hoping that someone can tell me if there is any particular frequency on that satellite that can be viewed visually on this device? I have used this a few times to locate the satellite but it would be great if I could visually see on the screen a working service. I am not sure if this is possible of not.

    On the spectrum analyser I can see good signal strength and normally if I was working with normal digital TV at that point I would press the DIGI button and it comes up with the lock and shows the MER etc etc. When I am in sat mode it doesn't lock or show any info other than it has a mode of DVBS and Symb.R. of 28588

    I am assuming that I can see anything as it would be encoded? Is there anything on this sat that doesn't need to be decoded that might work?

    Cheers,

    It is a miracle! I made it work! I found a menu that lets me select a specific satellite. It then allows me to go through the preprogrammed modes for that satellite. I managed to find a VAST service that has 34 programmes on it. The first two are viewable being VAST Info channel and the second one being Optus TV information. I can view both which is great.

    Details:

    Frequency - 12647
    LO - L01
    PR - 95
    PRG - 1
    PS - 0010
    P.ID. - 0801
    Volts - 13VDC

    Mode - DVBS2
    Symb R - 30000
    Code - 3/5
    Spect - Inv

    Question time:

    What should the BER, MER etc etc be for a good signal?

    Currently:

    CH BER - 1.93e-03
    BCH BER - 0.00e-08
    NM - 1.7dB
    MER - 8.6dB
    SNR - 8.7dB
    EVM - 37.3%
    PWR Index - Low
    CFO - 2.5
    RU - 0

    This doesn't mean a whole lot to me... The bar graphs on the screen don't look the greatest so I expect the above values aren't good...

    Your tuning is correct. I use those two unencrypted channels.

    VAST is very picky with alignment.
    Your figures are a tad low, but not bad.
    Minute LNB skew adjustment should improve those figures, followed by minute dish alignment.
    The post-viterbi (BCH BER) is showing 0 errors after correction, which is what you need.
    To simplify... use the bar graphs to obtain the highest figures.

    Thanks for the confirmation mate. Much appreciated. Sat has always been a bit of a dark art for me. Just fake it till I make it.....
