Got a couple of new LG TVs in the house over the last few months, so out of interest I had a look over the weekend whether I could lock the DVB-S2X TF1 Suisse transponder on 33°E (finally live somewhere with an unobstructed view from the garden past about 19.2°E!)
Couldn't lock the transponder on either TV, the only stuff that I got was the standard DVB-S2 France 24 HEVC transponder and the mainly encrypted Polsat Polish DVB-T feed one. Edision IP S2 also happily picked up the Bulgarian multistream.
I wonder if they're using different chips in the newest range of LGs that don't support S2X any more, or 12597 is just weaker than the other stuff and I wasn't quite aligned properly. The 25/36 FEC would be fractionally somewhere between 2/3 and 3/4 in terms of required C/N I presume so shouldn't be too difficult in theory.
