It may be signal overload as this is a very strong transponder I am getting 95% SQ with a motorised 88cm mesh dish + SX88+ Or you may need to reset the Lnb on your fixed dish set up, Not even slightest jumping with my set up, 12363 V 29500 is a stronger transponder 100% SQ with the same set up as above.
Its definitely something the way the Ocko channels are set up on 12168. Ocko is also hestitating every few seconds, TV Lux is fine. Ocko Star on 12363 is fine.
It reminds me of a less severe version of the problems the A1 channels had on YahSat 1 when one transmission parameter was set wrongly (istr short frames was mentioned by someone who had some analysis software??)
