SES2 87W
11805 H 11150
DVB-S2 8PSK

Ya may wanna check your reception quality as compared to yesterday or earlier.
Seems OK here, ~ 80% qual on the Openbox S9, and 91% on the Prof 7500 USB tuner.

edit: The SR was 12475 yesterday

http://en.wikipedia.org/wiki/Constellation_diagram

that should help explain what a constellation diagram is.
Basically if you plot the I & Q signals demodulated from a Phase Shift Modulated signal
like QPSK, 8PSK the more intense the dots are the better the quality the signal is.
I.e if the dots for each quadrant are scattered around more (i.e. noisy) that's indicative of a worse signal than if the dots are all concentrated in the exact same same spot (perfect world ideal case which of course never happens).

Combination of tweaking the dish today and conditions has made LPB strongest ever. Peaking up to 35% on this DVB-S2 is remarkable here. SES 2 blind scan brought in interesting stuff tonight.
