with this transponder I also don't have problem to get lock.

Yes, these transponders are those I couldn't lock. Other transponders with the 
same problem are transponders from Thor5 (0.8W) - 11341MHz V, 11421MHz H, 
11434MHz V, 12015MHz H and 12128MHz H. 

Changig RollOff to any value didn't get me any result.
