So, the problem is that the tp 12303 signal level is a little bit "weak". (86%, if I remember well 14,0 dB) in sunny day. Somehow the stb is not able to lock this tp
If I check the other tp on the same sat 0,8W is very high signal level. (100%, according to the internal measurement), If I visit the other sat e.g Astra, the signal level is still ok!

I tried to setup fine the level of the signal only (0,8W), with fine tuning step by step, and I found that I can increase it about 5%. Thats why I want to store this individual position, however the other positoins are ok.
I hope, my explanation was clear :-)

Anyway, very difficult to go to the disch at winter time.
I guess, the direction of the disch is correct, because of the level of the other sat-s. E/W also correct.
