I'm trying to lock on 21.5E 11449 MHz s/r 30000 , FEC 9/10 and with 8PSK
modulation (DVB-IP) .
i've increased/decreased the Freq by 4-10 MHz increments and also the S/R.
not any combination helped getting lock on the channel.
I've no problem getting lock on this frequency using factory drivers on
Windows XP, so it's a software issue.
the other S2 channels on the same position do lock without any change on
freq/symrate but they are QPSK and have lower FECs.
