Blind vs. Auto

[grasshopper]

Blind scan uses no information from the satellite TP list in your receiver, it scans the LNB Band, 950-2150mhz and looks for TPs, it then uses the LNB Freq you entered to save what it finds as TP Freqs in your memory.
So say it finds a TP in the LNB band at 974mhz it would add the LNB Freq YOU entered to that number, if you used the correct LNB freq like 11250 then you would get
11250 + 974 = TP Freq 12224
So 12224 would be saved to the memory.

Now sats like 61.5,82,91,110,119,129,148 have TP setups that FTAs can't quite ID everytime, so blind scanning on these sats can be hit and miss.



Auto/regular scan uses the TP Freqs in your FTAs memory for the sat you are scanning.
It gets the first TP freq, like 12224 then subtracts the LNB Freq, YOU have entered, from the TP freq to get the LNB Band Freq, so
12224 - 11250 = 974
It then looks at 974mhz and scans for channels at that freq.

It then gets the next TP Freq in your list and does it again, it does this until all TP Freqs in the list have been scaned.


As you can see both of these methods depend on YOU entering in the correct LNB Freq for the LNB you are using.
Sats don't have LNB Frequencies, they have TP Freqs, but for the TP Freq to have any meaning the LNB Freq must be correct.
All LNBs will have an L.O. number on them, that number is the LNB Freq.,
L.O. 11.25 = 11250
L.O. 10.6 = 10600
L.O. 10.75 = 10750

If you have no TP Freqs for a sat then blind scan is ok, it takes awhile since it is building a TP list from scratch and then also has to scan the channels on each TP found.

If you have a current TP List for the sat then auto/regular scan is better, takes less time and no reason to rebuild a TP List you already have.

If a TP has been changed or added on a sat it is easier to "add a TP" then scan that 1 TP than it is to start from scratch.

good info grass

[Jolypha]

That is some great info...I can finally say i know the diff between the two.

Thanks Grasshopper / Arboristman

As I'm new to FTA, most of this is greek. How do you add channels when auto/blind scan doesnt pick up?

[rodney174]

My preference for my superdish is I do a vertical blind scan and then I go through my channels and see which ones are missing and do an individual freq channel scan.

[blizzard4dish]

Thanks for good good info.

Can you pick up any mirrored channel on Dish using blind scan ?

[bille2007]

How do you do an individual channel scan on an ultra?

hello! everyone !
My name is tranphan5, i am new , i like to say hi to everybody !

[tranphan5]

Hi! everybody !

I need help ! I have my old flu is working fine with strenght signal and good quality > I have just bought a captivework-800s. I did the set up : download cw factory bin version 1.0 then the newest file cw800sv1.53 28/02/2008 and follow well the procedure. when i hook up the satellite cable to my captivework-800s ; there was no signal and quality at all. during the set up i did upload the file cx database v1.00 from my cw800s to do blind scan as people told me, and did not save it in case. What i did wrong? How i can have the signal and quality for my captivework-800s while the old flu : signal and quality is perfect ? Thank ! tranphan5 ./.

You just have to try moving the dish until you get good signal AND good quality. This can take some patience but once you get both you are all set to go. Might only get scrambled for awhile yet but you should be set to go for when situation changes.

Thats my advice but I am very new to all this.

some times I prefer doing a factory reset then a blind scan in order to get all the transponder that have been moved or added, something like "starting from zero"

[ni_bbs]

looks like you are missing Steps in Blind scan? what is it & how it works?
