It is definately not a strong signal, but Igenerally lock it fine with my 90CM.... most of the time.... however I suspect that time might be an issue. Ie I've watched the SCETV channels all afternoon at times last spring with no problems, then suddenly I'd lose it in the late afternoon.
Probably just my imagination, but it almost seems like they might cut their power a bit when schools aren't in session, which also may be an issue during the summer. I'm locking it fine right now though.
Also, I wonder if the reason some people here aren't getting it is because the parameters for the main SCETV feed listed in both your THELIST and in Lyngsat don't seem to be correct. I'd suggest doing a blind search on the sat, and it might show up with the correct numbers. The 2nd feed with only one channel does seem to be too weak or possibly gone for me.
