Not sure this is the best place to report what I just discovered. I use an S9 with SG2100 and a universal LNB set for 10600 and 22kHz ON so I only blind scan the high band. Here is what I just read on another forum: "With S9/S10, when using DiseqC 1.2 motor controls and manually “bumping” the motor position, the signal meter cuts out on vertical, making it difficult to impossible to peak on vertical transponders."I know a lot of folks have the openbox but I havent found anyone yet who is using a SG2100 with it.
I just tested this. And this is the cure to the problem I've experienced for a long time but never knew why. I could never manually bump my dish in diseqc mode to fine tune on some satellites. On other satellites I could. Now when I check, this has always occurred on vertical polarity tps. The signal would disappear and never come back as soon as I bumped the dish one time. So my solution is to simply tune a horizontal tp and then fine tune. Problem solved, as long as there is an active horizontal tp.
