what are Scanning Channel Differences

[Leveller]

What are the differences between:
Blind Scan
scan with Network
preset scan
And which is best and does network have any purpose with scan
Thanks.

Re: what are Scanning Channel Differences

A Blind Scan will search every possible frequency and not require a database, SRs or FEC figures to do so. Usually it is referred to Hard Scan.
Scan with Network- will scan freqs on a sat already pre programed.
Preset Scan: It will miss most updated frequencies.
The Blind Scan is the best scan available at the moment as it never misses a single frequency. It searches for all the possible frequencies.

Re: what are Scanning Channel Differences

there are also in most boxes.
scan 1 tp
scan free only
scan tv only
blind scan
network scan

hi

Little addition: blind scan indeed is the best ; but check if there are settings for this (eg how every frequency it scans) - take the less space between 2 freq., will take longer to scan, but then you're sure you have all. Best to use in combination of tobys tips: eg only tv. Also depends of the max. channels that can be stored in your box (certainly if you have more sats, the number of found channels can increase very quickly).

Re: what are Scanning Channel Differences

Some of the receivers have very limited channel storage space, like 4000 or 5000. If you are scanning Hotbird, Astra 19.0e and eurobird at 9.0e then its always better to search for only tv channels ubless you are interested in Radio. You still can do a blind scan but it wont scan radio channels.
I like Blind scan because all you have to do to start scanning without worrying about the frequencies and SR etc, and leave the receiver. After 10 minutes or so, everything is ready for you.

hi microchick

I don't know if it's my box or my internet, but a blindscan took me I believe about 1 - 1,5 hours only for 1 sat (only tv) - is said in my previous post, I scanned all frequencies I could. Just for info.

Re: what are Scanning Channel Differences

That doesn't sounds good.
*The internet is not involved in any activity of scanning or signal loss*.
I have recently set up a sky dish for Hotbird. The signal quality is not good which I believe takes longer for a scanner to read the data on that frequency. I do a lot of Blind scan during different times of the day for the best reception. It never took me more than 10 minutes. I leave the scanning on and go to get a cuppa and when I's back, its done.
*Please do check the setting on your box. I am sure there are a lot of guys agree with me.

I think it works where signal quality is excellent all the time. in my case some of freq. drop the signal quality in the day time. i f I do blind scan then some of channels are erased.

hi rizwan

Strange, never heard of that. As far as I know, and all the boxes I know of (sorry, no dream or VU+), only ADD new found channels to the existing list (mostly channelnumbers after the existing after any new scan). Never had any channel deleted.

Re: what are Scanning Channel Differences

I have heard of this problem before. Some countries in the subcontinent and Asia suffer from this problem. The problem is that Geostationary Satellites might have a nice circular orbit,but the Earth wobbles on its Axis during the coarse of a day. Thats why the reception gets worse during the day time.

hi

Yes that's true, but I was talking about the fact that certain channels are erased according to rizwan after a blind scan. That some channels/TP/channels have no good signal can be, but it's strange that the receiver deletes channels. This would also mean - and that's positive then - that old/incactive channels and TP's are deleted?

i think you should get better box
19east, on all my previous boxes took longest, latest box about 25mins

Re: what are Scanning Channel Differences

hi toby

no, it's a new box (have it for about 2-3 months or so), really no option (I think you remember why , and I made my choice ).

However, still surprised how come that channels are deleted (post from rizwan): anyone expercience with this? which boxes?

btw: regarding to my blindscan (can't check right now), but standard scan was freq. each '8', but I changed that into '2', which was less possible, just to be sure I got all TP's. Perhaps it's enough to set up '8', so time wil be 1/4th, so in this case I come to 15 - 22,5 mins, this is what's apparently normal.

Re: what are Scanning Channel Differences

According to Toby, 15-22.5 min should count as normal. I must say openbox is much faster than that.

all different boxes will all be different scanning times.
