(By the way I learned that move by reading this site) I did find those birds very easily and adjusted my elevation and compass settings. Next I switched back to my linear LNB but could still not get any quality for T5 (G25). I had my transponder frequncy setting at 11836 which lyngsat shows many free channels. I used usals to get me to the bird but it showed no quality no matter what I did. I decided to try a satellite scan which did bring in about 15 channels but I knew there were a lot more channels then that. Then I did a blind scan which did bring in all the channels on G25.
Question: What's the difference between those two scans and why I still get no quality in the menu for G25 on frequency 11836.
Thanks for any help... Johnny |
There are basically 3 types scan (4 including network).
1. Transponder scan, where you select a transponder, and scan just that transponder.
2. Satellite scan. This scans all the transponders that are saved in memory on your receiver. Similar to transponder scan, but scans all transponders.
3. Blind scan or power scan, etc. This scan actually FINDS the transponders and determines the proper SR values for each transponder.
The problem with transponder and satellite scans is that if you don't have the proper frequency AND SR value entered into the transponder list in your receiver, then it won't scan in any channels. And these transponder parameters change often, so the odds are that many or even most of the transponders stored in your receiver might be out of date.
Above you said that you used 11836 freq and found nothing, but you didn't mention what the SR value was. If the SR is wrong, you normally won't scan in any channels.
Also, if you have the wrong LO freq entered for that satellite, then the transponder or satellite scan won't scan in anything, however the blind scan WILL, however all the transponder freqs it finds will be saved with an incorrect frequency.
The 4th type scan is a network scan, which is like a transponder scan, but when it scans a transponder which is part of a network, it will then extract information about other transponders in that network from the signal, and then try to scan those transponders as well. Again, this won't work if the LO freq is set wrong.
The fact that blind scan worked for you makes me think your LO freq is wrong. Either that, or the SR values in your saved transponders were wrong.
