The blindscan plugin that is used in enigma2 receivers today was created by a person that is unknown to me.

The blindscan plugin that is used in enigma2 images today was modified by, and is maintained by Huevos. The original blindscan plugin did not have c band capabilities. Huevos added the c band capability, and more recently add Ka bands, and some other tweaks to the blindscan plugin. The work and maintenance of the blindscan plugin by Huevos has helped us tremendously in North America, and is appreciated!

The blindscan plugin is really based on one lnb, which is the Universal model, and has a pair of l.o. frequencies that are 9750, and 10600 MHZ. Code has been added which allows c band (5150 MHZ), standard ku (10750 MHz), circular (11250 MHz), and some others such as ka to work. But it is important to remember the original design of the blindscan plugin which is universal lnb, because code to make the other lnbs work is based on the origina, dual l.o. universal lnb.

There are usually several different ways to setup a lnb in the receiver where it will work in blindscan, and it could be said that there are three types of settings which are: My Settings, Your Settings, and the Correct or Suggested Settings. Really it does not matter what you use so long as the receiver functions as you would want or would like, but for this thread, we will try to focus on and discuss what the correct blindscan setup and the correct lnb settings which are based on the blindscan code written mostly by Huevos.

Universal lnb's have a high and low band with 10600 MHZ as the l.o for the high band, and 9750 MHz l.o. for the low band. The universal lnb switches bands by using the 22KHz tone.
LNB's that have a single l.o. such as a common c band lnb will be ran through the blidnscan plugin in the low band, with coding in the plugin changing the transponder frequencies so they read correctly for us. It is not a good idea to use a 22KHz tone switch for connection of two single band lnbs that are to be blindscanned. The 22KHz tone tells the blindscan to switch to the upper universal band. Some receiver such as the OSMIO4k will ignore this on a single band lnb, but other receivers may try to switch bands when a 22KHz tone switch is used which will result in transponders being displayed wrong and missed transponders. So if possible, eliminate any 22KHz tone switches for single band lnbs that you want to blindscan. Or at least understand what can happen if a 22KHz tone switch is used on some enigma2 receivers that blindscan.


There are several other settings for blindscan that will be easier to cover or explain using screencaps, so the next few posts in this thread should contain a few screecaps or pictures with written explanations. There are a lot of settings or combinations that many users do not know about or do not know why they exist. The blindscan plugin contains filters that will look at the transponder list for satellites close by, and delete those transponders if they are found in a blindscan. Other filters check for duplicates, and may remove transponders that are found closer than 4 MHz apart if certain conditions exist. I will try to explain all of this to the best of my limited ability, then open this thread for questions or comments. EB
