Huevos started updating the blindscan plugin a few days ago. He was nice enough to take some input and give us some things we really need in the blindscan plugin for North America. I will review what has changed and what is updated or added in this thread.

Older receivers had trouble with blindscan and the drivers for the tuners that control blindscan were poorly written. Any receiver after about 2014 usually had improved drivers except for Vu+ and maybe a few others. The Vu+ Duo2 needs some filtering of the blindscan data or you will get garbage, such as transponders with the same frequency and polarization but with different symbol rates.

A filter has been in the blindscan for a long time. This filter looks at the transponders in satellites.xml and makes corrections to the transponders found in blindscan. North America does not have a good satellites.xml as compared to most of Europe for many reasons. So the blindscan transponder filter has never worked as good in North America as it does in Europe.

We also use a Standard lnb with a 10750 l.o. while most of Europe would use the Universal lnb. When the blindscan plugin was originally built, it only worked for one type of lnb which was universal. Huevos added the C band lnb to the blindscan, and now has correctly added the 10750 lnb, Huevos also added Ka lnbs and other features to the blindscan plugin.

Please remember when you use these features who made them possible, and Thank Huevos for them. Correctly installing the 10750 lnb and adding other features took a considerable amount of time, and a lot of it was done for North America.
 
Disable sync with known transponders
SYNC.webp

This feature will disable the blindscan filters and allow what the receiver actually finds to be scanned, including any errors. The OS Nino Pro seems to work fine with this filter disabled. The Vu+ Duo2 will return some garbage when this filter is disabled.
(Default = OFF)
 
User Defined LNB Settings
View attachment 15339


Many different User Defined lnb settings may now be used. The math is automatic, and should work for most lnbs that have l.o.'s above 9750. Shown in the above screen grab is the universal lnb set for the 10600 l.o. This was done so I do not have a 4 step blindscan when only two steps is really needed.

10750 L.o. lnbs should also now use the User Defined setting instead of the old Circular setting.

Ka L.o.'s were also added to User Defined. I do not think we have any Ka satellites active at this time, but Europe does.

Error messages and other safeguards have been added in order to help keep the receiver working correctly.

Attached is a test plugin that works for the OpenVix (OE Alliance) Image. Feel free to test and report what you find. Be sure to ask questions on anything you are not sure about. For those that cannot install this plugin, a version of this plugin will be in OpenVix images soon.

Path to blindscan plugin is: /usr/lib/enigma2/python/Plugins/SystemPlugins/Blindscan

Backup the whole Image before installing anything like this. A Backup is not mandatory, but it is a good idea.

The OE Alliance blindscan plugin will not work in OpenPLi images. I am running this blindscan plugin in SatDreamGr which is part OpenPLi, but I had to make a few changes to get working.
 
Got the blind scan folder and box branding for the OEA core after adding the new plugin.py and reflashed Openpli 7.0rc, transfered files. Got it working on openpli. Thanks EB!
 
Set "Disable sync with known transponders" to Yes. See if you scan more transponders like that. I do not think the Zero 4K needs that filter.
 
Setting "Disable sync with known transponders" to yes caused it to scan a differnt frequency and I got duplicate channels. Say my known transponder was 11842 and the blind scan found 11843 you get the same channel on both frequencies so I think it is probably best to leave it set"no".
 
The duplicates didn't appear in the service scan from the blind scan. You find the duplicates in your Satellite services with the zero 4k. Set to yes would be alright if you are just setting up the receiver and didn't have any channels saved in satellite services with the default known transponder. Just don't make a new blind scan and use no with disable sync with known transponders or you could get duplicates in the satellite services. 97w ku is the satellite I found the duplicates. A wok around would be to update the satellite .xml with the found frequencies from using yes during the blind scan,

Tell you the truth circular lnb setting is working. I forgot to set user defined 10750. when I scroll over to user defined from circular it was set 9750lofl,10600lofh so it was definitely using the circular lnb setting. found the same amount of channels using both settings. But I will leave it set to user defined 10750.

No, not clearing. I am trying that now with (yes) desync known transponders. ok clearing messed up my favorites. Get a lot of <n/a> in my favorites list.
A rescan with clearing and NO fixed the favorites list.

That is because the transponders are being found on a slightly different frequency than the transponder that the favorites were made with.
 
Yes that's the issue. I like the desync feature but I think the satellite .xml will need to reflect the same frequency as the bindscan finds. I know how to edit the Satellite .xml file to make it custom. Only thing everyone would have to use thier own custom .xml file if they don't want to have the issue of selecting yes desync known transponders.
 
EB, you know what the (Yes) disable sync feature will work fine for me on 91W and 105W. I just wont use it on 103w or 97w where most favorites are. Then I shouldn't have any issues.
 
Save your settings before you scan, then reload settings when finished. That takes 2-3 minutes to restore everything the way it was, and cleans up any messes that were made.
 
I re done my fav's with the new frequencies and reflected them in my custom satellite .xml file so I should be good on 97w and 103w. Just can't use clear before scan on 103w because it will delete the Radio channels. Should not make much of a mess now.
