Eutelsat 13B 12303V

[Adam792]

Checked this one yesterday and today and I don’t seem to be able to lock it any more.

I get verticals either side OK - 12265V and 12341V.

The alignment of my dish is certainly off a little bit since the storms in recent weeks, but I’m surprised that 12303V would be so much weaker than the other TPs that I would lose it completely. I’ve lost 1dB or so on Astra 1 which is at the focal point (Sky Zone 2 with multi-bracket).

Can anyone confirm that it’s not as strong as the surrounding frequencies?

12341V is the weakest out of those three here, though needs less signal to lock (5.2dB S2 QPSK 5/6 vs 7.9dB S2 8PSK 3/4 for the other two)

12265V 14.8dB
12303V 14.1dB
12341V 13.3dB

Thanks @ozumo - that would make sense actually, I hadn't properly checked the strengths of the surrounding two but they match what you've found -

12265V 9.5dB
12341V 6.9dB

So with 12303V between the two, it's probably somewhere just below the 7.9dB lock threshold for 8PSK FEC 3/4. I'll be up my ladder when the weather improves a bit!

I think the multi-LNB bracket must have taken a bit of a battering and gone off alignment, Astra 2 on the other side is much poorer than before too, although copes because of the sheer strength of it.
