Can you please get the log for (with STB0899 and STB6100 with verbose=5)

a) 3 Mhz

1) a complete cycle with a LOCK, including where it calls track.
2) 3 complete cycles where it fails to LOCK, including where it calls track.

b) 10 Mhz

1) a complete cycle with a LOCK, including where it calls track.
2) 3 complete cycles where it fails to LOCK, including where it calls track.

with both DVB-S and DVB-S2 modes, for the same frequency for each.

Please be careful as not to mix up the logs.
