92.2°E ChinaSat 9C

Quote from Tomek22

12520 H 30000 4/5 DVB-S2 QPSK

Thanks Tomek22 for your report here.

According GSO satellites powered by hvdhChinaSat 9C doesn´t fit this range.
ChinaSat 9C ranges: 11.70 to 12.10 to 12.20 GHz
as far as I understand...

PS: 91.5°E MEASat-3b is near to this position and fit this range.

Lacking a frequency plan, I just assumed Chinasat 9C would be similar to Chinasat 9 (which is still nearby at 92.4°E with a little inclination).
The choice in these cases, is show something that is probably mostly right, or show nothing at all!

Hello i found something around 92.2°E it should be Chinasat 9C.

Signal is very strong, frequency is empty.

12520 H 30000 4/5 DVB-S2 QPSK

Please someone confirm is it Chinasat 9C or something else.

On spectrum from 11800 to 12200 R/L freuquencies are visible

Thank you, Tomek22, for finding this trp.

Yes, it seems to be ChinaSat-9, but it would be too good to be true, because such a strong signal in the European area from a Chinese satellite seems unlikely(?).

But let's wait for more data on our DVB applications to be sure what this signal is.

For now, I have captured a stream without anything tangible.
Now I can only confirm what you found.

I'm not home today, and I can't even locate it. I'll report back on this position tomorrow before noon.
Regards

I have my asked my friend in China to check it though he's not online very often so reply may be slow.

The signal is very strong in my H polarization.
I changed the polarization to V, and the signal is slightly above 6 dB.
I couldn't find any channels in the blind.

I don't think vertical polarisation is activated, but because of the very strong signal on the horizontal, it appears on this polarisation. It doesn't seem to be a carrier test, so we should expect something else.
In such a situation, it is an opportunity to precisely adjust the LNB to ensure it is of good quality, provided it is a quality product.

I do this every time I change my LNBs to eliminate noise and get a better signal, even if it's only 0.1 or 0.5, not to mention it can often reach 6dB, as it appears in your receiver menu.

Of course, we don't know whether the operator of this transponder plans to transmit on both polarities, but if not, then the LNB must be adjusted and the noise eliminated. With weak signals, this percentage matters if the signal is at the limit.

However, there is also the possibility that the same signal is transmitted on different spots, as we have in the Ku band at 40.5W.

It's just an opinion.

Regards,

I get around 19.2 db on a 120cm dish.

12522 V is from 91.5E which can't be locked.
