Thank you very much everyone!
Your help has been very useful and instructive.
I played around with the azimuth, with the tuner set at 1512.500MHz, to see what signal I could get.
The receiver locked on 4 different satellites. I could easily observe distinctive peaks of signal power around each location.
I swept about 60 degrees around South. Three were on the edges of that angle window, one was close to the theoretical direction estimated via www.dishpointer.com + landscape reference.
This method is a good start, but I found it difficult to visualize a central axe on the dish to aim at those references in one view.
So I assumed it was reasonable to end up with a couple a degrees off (5-10) to the actual observed power peak with signal lock.
The fact this "locking" position is a bit to the right of the supposed Hotbird 13°E position corroborate my idea that I found the correct satellite.
With this on field observation, I am now thinking that I would probably not see a significant power drop between Eutelsat 9A and Eutelsat 10A considering they are 1° apart from each other and there was clearly no such signal peak at this frequency in a 15° angle window around.
Here is my new signal lock:
RX1: Active, Locked
EUMETCast DVB-S2 T1 1512.500 MHz, DVB-S2 8PSK 3/4, 29.996 Msps, CCM, 11.8 dB
RX Status 1, Configuration 2
1. Tuner Status Locked
2. Demodulator Status Locked
3. Transport Status Not Locked
4. Demodulator Frequency Offset 2348 KHz
5. Demodulator Es/N0 11.7 dB
6. Signal Input Level -28.0 dBm
7. Demodulator BER 0.00 e-7
8. Bad Frame Count 0
9. Bad Packet Count 0
A. Demodulator Link Margin 3.5 dB
B. Modulation Order and Code Rate DVB-S2 8PSK 3/4
C. Link Adaptation CCM
D. Pilots On
E. Frame Type Normal
F. Roll Off 35%
G. FPGA Loaded
Although I realized afterward the 22KHz was ON during my azimuth scan, with a tuner frequency set at 1512.500MHz, I saw the demodulator frequency offset dropping when I desabled the 22KHz, SNR increased, and the signal status remained on "locked". So I guess this is not a problem.
Transmission Standard is correct (DVB-S2), modulation is correct (8PSK), code rate not exactly (3/4 instead of 3/5), but it was varying a lot in the beginning.
I believe I am now very closely pointing at Eutelsat 9 or 10.
Unfortunately, as you can see the Transport Status is still Not Locked, while I do receive some packets.

What does the Transport Status actually means?
