    Hi Guys

    Anyone having issues receiving any of the channels on transponder 12525 / 29999 H | (12526 , 30000 H )

    Some of these channels are Balkanika , Planeta Tv , Music TV(MAD) Star gr , Kontra, Sport TV, Chanel 9 , Alpha gr,

    I get a No signal quality on that transponder , all others are fine, 10700 lnb is been used.

    Thanks

    I am in the same boat....that transponder is the weakest and if your dish is small and you did not tune it to the max ,then you end up with weak signal or no signal at all.Make sure there is no bird poo on the dish as well, cause my Serbian neighbor had to clean the bird shit to get the signal back...lol...and I am not joking cause that really happened.Also try the LNB skew to get the best possible signal quality .....good luck

    The most usual issue is losing it due to poor lnbf skew. As the same freq is used on Vertical for Feeds like the cricket.

    Sorry if this seems kind of silly to ask, but you said you changed from a 10700 to 11300 LNB. I am sure you probably did, but just as a test, did you remember to go back to the decoder/STB and input this new info into the LNB setup menu?

    I think that you have to use an 11300 lnb, if you aren't already using that.

    No. You could also use a universal 9750/10600 if that took your fancy.

    Ok guys just got off the roof.

    New dish installed Azure Shine 80CM dish with supernet 11300 LNB. The satellite finder picked up all transponders apart from 12526 , 30000 H . So FTA chans were showing on meter and viewable. Had to get off the roof as it started to bucket down. Came down plugged box in & Missing chans all scanned up fine & working. Strange how meter cant pick em up but box can Probably only a MPEG 2 meter. SS 50: SQ 70 on box .

    Aww well everything seems to be working now thanks for your time guys looks like its fixed Not sure if old dish or lnb was causing issue but everything seems sweet now

    OK, It's great that it's working again.

    About the LNB's though, I think it might be better to get a universal or 10700 eventually (opposed to 11300) as future expansion into the rest of the Ku-band is always a possibility I think for any satellite fleet, even if it is Optus (who have been using the same band - 12.25-12.75 GHz with LNB thus 11.3 GHz - since the days of the Aussats). I know they have been recommending 10700s for all the VAST guys.

    These older LNBs (like the 11300) all get phased out eventually. For example, I don't even think you get 11475s anymore, even though they were popular (e.g. the Cambridge brand). But, those days 12.5-12.75 GHz was more than enough space for any operator.

    I see even Optus sats are now using frequencies in 11.7-12.25 GHz along with 12.25-12.75 GHz, hence the move to a 10700 LNB.

    AdrianR The specifications on the LNB box show the following Which is def the ranges for 11300..

    Frequency Range 12.25 ~ 12.75GHz
    L.O Frequency 11.3Ghz
    Noise Figure 0.35dB
    Image Rejection 50dB
    Crosstalk Isolation: 27dB

    I got a couple lnbs here by they are all 11300, might keep it untill expands then will change over to 10700, atm i dont see tv plus expanding anytime soon

    Intelsat is fine for a 11300 lnb because all freq on that sat are between its bandwidth 12250 - 12750 MHz. The Optus sats work over a greater bandwidth hence the requirement for a 10700 (11700 - 12750 MHz). A universal 9750/10600 works over the largest bandwidth (10700 - 12750 Mhz).
    So any will do the job on this sat. But the 11300 is no good for the Optus sats.

    I know that comparing signal strength/quality across different bits of gear is fraught with danger….but it seems to me that the levels you are experiencing are a bit light on.

    Using a 90cm Phoenix dish and Strong SRT4922, I’m getting SS 97, SQ 90 on 12525.

    On my DVB-S2 meter, SS 94, SQ 81.

    Took me quite a while to get this transponder right, and I found that if everything was maximised to one of the DVB-S transponders, things weren’t as good as they could be with 12525.

    In fact, I couldn’t really get any sense out of that transponder until I specifically peaked everything to it.

    I think that if you can figure out a way to peak dish and LNB on that specific transponder, you will probably be able to squeeze quite a bit more out of it.

    Could be handy on a rainy day...

    Yeah, that's true. I wonder sometimes when or if Ka-band will become the next "home dish" standard like Ku-band did in the 80's and 90's. That would mean much smaller dishes for a start, I would imagine. I saw maps over USA once for one of those DirecTV sats (or Dish Network, not sure) which showed peak beam values of like 70 dBW.

    Those are good. They normally have a gain of about 65 dB too, don't they?

    Don't the gains differ when you use the different types? It could just be me, but I remember universals (9750/10600) having a gain of about 55 dB. Although, come to think of it, I don't think that affects C/N ratio (essentially what controls signal quality). I would imagine the LNB amplifies signal and noise (ratio stays the same).

    Anyway, we know the bigger dish (65 to 85 cm, right?) did the trick of course, and the problem is solved now.
