Fortec channel scan getting stuck

superd46 · #1 (**permalink**) 03-22-2006, 10:06 PM

I have the Fortec Lifetime Ultra. When ever I do a blind scan sometimes I pick up a transponder with a symbol rate of 7.957Msps. When it finishes looking for transponders and try to do a channel scan it gets to the 7.957 and gets stuck. I've had it going for over an hour and it never gets past it. It doesn't matter what Down Frequency is I've had 12061, 11791 and some others and always gets stuck. My friend has the Ultra too and his does that same thing. Any ideas one why or how to fix it.

Right now I just have to exit out and then do a TP scan and pick up after the bad one.

You don't say whether you are slaving your Fortec to a big dish or if it is direct connection to an lnbf. The reason I ask, is that I've run across a couple of transponders that will lock up the Ultra too, I think they were on the KU side of either IA6 (T6) or IA8. I think that they are transponders that don't have a PAT or PMT or something like that, perhaps IP data, and the Fortec just sits there waiting for the channel info to come through and it never does. Since I'm using a slaved system, what I do when this happens, is just flip the polarity on my analog receiver which I'm slaved off. What this does is kill the signal the Fortec is locked on, so it gives up and goes on to the next transponder. As soon as I see it switch, I flip the polarity back to the proper polarity, and it continues on and finds all the remaining signals. I think the signal that was doing it to me turned out to be an IP/DVB data feed, but it wasn't on all the time, so it didn't always do it. But I remember being very annoyed once when trying to find a preseason NFL game last August, before I figured out how to get past that freq.
If you are NOT slaved, then you wouldn't be able to use that trick though, so I'm not sure what you could do other than what you are doing.

In addition to what wejones said, you could also stop the scan, go to the TP menu and delete that TP. Rescan (regular not BLIND SCAN) again and you should be fine.

Thanks for the info.

I have the reveiver plugged directly into the LNB. I'll just have to keep going around it the way I have been. I do delete the TP from the list after I'm done. Whenever I am feed hunting I tend to blind scan so thats when I get them.

I'm not sure you picked up on what Sadoun suggested, ie after you do the blind scan, and get stuck, and then delete that offending transponder, you don't need to do a blind scan again, because you've already done that, and the transponders have been saved. If you then do a satellite scan, it will look for signals on all the saved transponders determined in the blind scan, minus the one you deleted. This will save you the time of doing another blind scan above where it froze up, which I "think" is what you are doing (I know that is what I had been doing before I thought of the polarity switch thing). Anyway, I think Sadoun's suggesting should save you some time.
Was this the signal on IA8 BTW? I think that's the only place I've seen this behavior.

I do the blind scan once and then the TP scan and pick up where is left off. I get one on IA6, IA8 and think one of the AMC's. I started noticing them more when I was seaching for Mardi Gras feeds in Feb and this month when I've seached for NCAA basketball feeds. When I first got the reciever in October I did a blind scan of all sats and I don't remember it happening at all.
