[QUOTE="zg3409, post: 789357, member: 378078"] Hi Viperscan, I have read all your posts on this thread. It may or may not be possible to get the signal in Manchester. From what I have read you may be following the wrong procedure to get a fix. Even if you get a signal, in time it may dissapear if the same frequency is used by the East Scotland spot. Firstly dish size is a bit of a misnomer. A smaller dish MAY, I emphasise may work better, in terms of alignment etc. A very large dish is very, very directional at KA. (Think of pointing a 3M dish!) Ignoring actually getting a TV signal first, if you have a fast acting spectrum analyser you should be able to align even using a camping size dish to 9 East. What seems to be recommended is to use an ordinary KU univeral LNB first and align it to pick up the normal TV channels at 9 East. See lyngsat for normal 9 East channels broadcasting from 11-12Ghz. Once you have the dish aligned correctly then swap out the LNB. The local oswcillator you mentioned near the very start is TOTALLY wrong, so remove that from your settings. 99% of receivers do not have an option for a 21.2Ghz LNB, so what you need to do is use the settings of a normal LNB, and set up a custom transponder of 10,765 Vertical. KA-SAT @ 9E 20.185GHz, Left Circular Polarisation, DVB-S2 QPSK, SR 25000 with 1/2 FEC . Any DVB-S2 HD satellite receiver can in theory be used to receive Saorsat as the Ka band LNBF converts to a regular IF in the 950MHz to 2100MHz band. If the receiver does not have a setting for the Ka band LNBF Lo, then a "fake" frequency 10.765 vertical rather than the real 20.185 may be entered when using the Inverto LNB with local oscillator of 21.2. [B]HAVING LOOKED AT THE ATTACHMENTS YOU ATTACHED ONE OF THE IMAGES LOOKS LIKE THE CORRECT TRANSPONDER !!!!!!!

I would recommend ignoring all the 20Ghz values above and just use the 10Ghz values and a univeral LNB setting. It does work!! If you cannot get an actual TV signal with the above info then all is not lost. There are other spots transmitted towards East Scotland and France using the same frequencies. There are also other spots (different polarisation, different frequency) that should be REALLY strong in Manchester. You should be able to use a camping (40cm) dish to pick these up. Every other spot is all internet, no TV, so no point trying to scan for TV on them. However they could be very useful for aligning the dish. Search for "tooway dish pointer" and see what spot is recommended for your location. This "colour" determines polarisation and frequency for the strongest signal at your location. This should confirm you have dish pointed perfectly, let me know what colour and I can tell you what frequency to set. The spectrum looks good. Make sure your box is HD and LNB setting is universal. Let us know!!!! Please ask any qns if confused [/QUOTE]
