91.5°E Measat-3

  • Hi, N_Stanislav,


    If you are still testing and receiving in the eastern part of the arc, it would be interesting to know if you can receive Chinasat 9 in Ku-band with circular polarization at 92.2E with coverage over Asia. This satellite uses the ABS-S system.

    I had read somewhere that the M88rs6000 chip could also be used for ABS-S reception. Of course, I am not sure about this.

    So far we have no evidence of this. But even if it is not true, the reception of the Chinasat 9 would be a performance in itself. So far only Roman David of Dxsat has achieved this in Europe.

    I don't know what the chances of catching this satellite are, but I think it's worth it. According to Lyngsat, you are one of the people who catch the 93.5E satellites.

    I don't know if DX Bozóth can receive Chinasat 9, but if you did, then you would be the second dxer to go far with his antenna, according to what I have read,

    Fingers crossed. :51:

  • I would send you the lnb Ku circular if I were sure it would reach you, taking into account the not-very-favorable communication conditions between Russia and Europe.

    If it is still possible give me your address via pm.

    There is also the possibility to insert a plate in a waveguide to a linear lnb, like in the picture.

    With the plate mounted in this way, you get good results in circular reception.

  • satesco according lyngsat, this tp should receive also on linear LNB.



    But i don't think that Crazyscan software recognize ABS modulation.


    I try to receive Digicipher2 - and also crazyscan don't recognize this.

  • Forgive me, maybe I don't understand English well, but R means right for Circular polarity, and in Linear, it means Vertical.

    But I'd rather send you to the website of Roman David who managed to receive Chinasat 9 14 years ago, where he explains how he managed to lock this signal.

    By the way, Crazyscan can find all kinds of signals, even on this one, the problem is the hardware support able to lock it!

    See the example with Novelsat, which it finds but the demodulator is not the standard one used by most of us. For this reason, we have to use this demodulator dedicated by the operator/provider to their customers.

    In the Asian area, such receivers are found. I assume that these demodulators are used by terrestrial/cable providers. Probably for these reasons, they are not so popular or talked about.

    So, if you manage to orient the antenna to 92.5E, you can try Crazyscan even if you won't receive the programs with the devices you have.

    Important to see the signal.

  • I first tried it when I took the antenna to the far east, in 2013, but it needs a slightly larger antenna, I estimate at least 3.20m if I look at the satellite footprint. Or with my 1.50m antenna, I don't even think I could see a signal.

    Incidentally, for objective reasons, I can't install a larger antenna. I'm glad I can use this one now.

    I was thinking that with your 3.0m antenna and being closer to the footprint you'd have a better chance of receiving Chinasat 9(?).

    I'd say whoever receives it, can say it's a real dxer's catch, like this Slovak, Roman David. Hats off. :70:

  • If I'm not mistaken, some of the muxes on your spectrum are from Yamal 401.

    Understandably, it has a stronger signal than the Asian one. That's probably why you have a weaker signal on Measat, even if you have a relatively large antenna. :3:

  • This sunny clearly morning i can lock Cambodia channel on the limit! really DX receiving! :34: Picture not stable, lot of freezes and crashes. Only 6904SE get lock, other cards not lock.
