Thanks midwestmac,

Just another perspective. One of these days gotta do more work on it.

Have you tried it with pendragon's system?

Yes I tried, ran into an error with  struct dvb_fe_constellation_samples const_samples
and GET_CONSTELLATION_SAMPLES.
Because I don't have those defined in my frontend,h, I would need "capture constellation"
so I'm still reading and thinking about how to add capture constellation

Correction on this 95W Ku   I can not lock this signal 12082 H 20160.
and still using pendragon STV0900 driver w/ prof 7301
I think if I have the Ber set right in Tune-s2 it reports the Ber with errors.
95W 12080 H 20160
Code:

Tuned specs: 
System:     DSS 4 
Frequency:  12082 H 20160 
22khz:      ON 
Modulation: QPSK 0 
FEC:        2/3 6 
Inversion:  ON 1 
Rolloff:    35 0 
Pilot:      OFF 1 
MIS ID:        -1 
FRAME_LEN:  LONG 0 
Bandwidth:  27.2160 MHz 
Data Rate:  24.7718 Mbps 
status Unlocked | signal -46.356 dBm |snr 16.005 dB |ber 318181818 |

Same thing with the G25 Ku signal.
G25 12148 V 20160
Code:

System:     DSS 4 
Frequency:  12148 V 20160 
22khz:      ON 
Modulation: QPSK 0 
FEC:        2/3 6 
Inversion:  ON 1 
Rolloff:    35 0 
Pilot:      OFF 1 
MIS ID:        -1 
FRAME_LEN:  LONG 0 
Bandwidth:  27.2160 MHz 
Data Rate:  24.7718 Mbps 
status Unlocked | signal -46.851 dBm |snr 14.898 dB |ber 317880794 |

But here's a regular DSS signal on 95W Ku
95W 11840 H 20000
Code:

Tuned specs: 
System:     DSS 4 
Frequency:  11842 H 20000 
22khz:      ON 
Modulation: QPSK 0 
FEC:        2/3 6 
Inversion:  OFF 0 
Rolloff:    35 0 
Pilot:      OFF 1 
MIS ID:        -1 
FRAME_LEN:  LONG 0 
Bandwidth:  27.0000 MHz 
Data Rate:  24.5752 Mbps 
status Locked | signal -53.561 dBm |snr 13.118 dB |ber 0 |FE_HAS_LOCK 


So I don't know? why these signals  give me this "Ber" report like this.

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
