Es'hail 2 Commercial TV Transponder question...

  • Ok... My question and the reason for asking it was based upon fatally flawed thinking!

    I am setting up a 1.2metre dish for QO-100.... I have an Green Octogon Quad LNB

    I chose the Quad LNB because I want to feed & run my Air-Spy SDR independently of the amateur radio download/upload side...

    Ok, so I thought a good strategy would be attach my little Edision Progressiv HD Sat Tuner


    and to initially line the dish up onto the Sky Satellites @ 28.2E

    That all worked well... So the next step was to pick a FTA DVB-S transponder on the commercial Es'hail satellite and tune the dish up on that as a precursor to accessing the QO-100 Amateur Transponder...

    That failed to work and it took a while for the penny to drop as to WHY? But, Hey! this is all a learning curve... But it was so obvious that I should have realised it in the first place !!

    So what was the flaw?

  • Hi David,

    But what has this to do with the EPG data? I did not get it...

    For the first alignment BBC Arabic is a good starting point, not on Es´hail-2 but close enough on Badr4.

    For fine tuning later on the beacon can be used.



  • Best find another receiver. I think it can be re-programmed. You also need to chose the right FTA signal that's actually receivable in the UK. Better way, align on 28.2 then attach your airspy, if necessary via a suitable downconverter, and look for the transponder while moving the dish a tad to the south.

  • Thanks for all the replies...

    The Sat Rx is fine and is programmable for many different satellites...

    I have had no problem lining up on Sky @ 28.2

    Being able to decode the Es'hail EPG data was just a bonus for me, to prove I had learned to set up the Sat Rx

    Thank you for the suggestion to use Badr 4 BBC Arabic (on TP 15)

    Looking at the TP Footprint @ I can see THE UK IS COVERED !!


    The Es'hail TP footprints @ does not cover the UK, not even France....

    So I was attempting "mission impossible"...

    So now I will go and try a lineup using Badr 4


    David G8HJT !!!!

  • Yes, success... My Sat Rx was very easy to set-up.... It has a "Blind Scan" facility and so scans all the standard EPG channels and soon builds up a "TP Table" and a channel list for that satellite !!

    Just a quick nudge to the right on the dish and "Hey Presto!" there it was.... RESULT !!



  • A good way to line up is the beacon MER on wideband, with no others using the transponder it should be 11-12 dB. For DATV this is what you want optimised and once it is, narrow band will be more than good enough. On Narrow band you need to maximise the beacon amplitude, not the SNR because that dish will see the transponder noise floor well above the background noise and it's hard to tell improvements.
