Right, But I am not crazy, this thing is wired. Sometimes I will set up to scan say sbs by moving the dish to it with the motor and then save exit and go straight to blind scan and it will have sbs checked off and then when I start scanning it scans amc3 !@#$%^!! I am having fits with this, the worst thing is it is unreliable, it will lead you to belive you have problems elsewhere because you caint pull in a channel with a blind scan when all along it is the reciver. I have not narrowed it down to high or low transponders but it aint right.
I've not seen these problems with my Viewsat VSPRO. I think it had some troubles moving the dish initially that was fixed by a firmware update. I was using USALS.
I have found that it is best to have at least one channel scanned on each bird so you can switch to that channel and be assured the receiver won't try to move the dish. For example if you're on AMC3 watching a channel and decide to blind-scan SBS6, the receiver might try to move back to AMC3 due to that being the "current channel" it is watching. This would be a bug since it shouldn't move the dish when you're in the setup menu, except to where you're asking it to move. Even if it doesn't move back, it might not move until you begin the blindscan and then it will possibly miss some low transponders as the dish is still moving when it scanned 11700mhz for example.
Anyway, I might be doing something wrong, but with Viewsat and Coolsat I have occasionally had this issue of keeping the dish locked on the bird I want to scan. The channel fixes it for me. So even on satellites that normally have no FTA, just feeds, I will leave one entry to help me lock the position.
Imagine the worst case, you're watching WhiteSprings on 129° and decide to blindscan 72°, if you just pop into the menus and do it, the receiver might not really wait for the dish to get over there. Even the fastest motors with 18V will take 23 seconds to move 57° That is a lot of scanning to miss if the receiver doesn't wait properly.
If I don't have a channel scanned on the satellite I want, I just move right next door so if the receiver screws it up it will only be a few degrees.
