<div dir="ltr"><div>I have 2 "bad" transponders, one with 30000 2/3 and another with 27500 2/3</div>
<div> </div>
<div>So I don't think its symbol rate related. Although there is a problem with FEC lock, I don't think modulation (2/3 or 3/4) is related either.</div>
<div> </div>
<div>Since DVB-S scan algorithm also had problems with FEC lock I have a feeling the same problem exist in S2 scan.</div>
<div>I'll try to play with it when I'll have time.<br><br></div>
