OCTAGON SF8008 - RDA5815 modification for openATV


  • Hi All,


    I tried to get the SF8008 running without modifying the LNB but had no success...


    After reading this thread a few times more I recognized that it is already mentioned in the posts.




    I would like to summarize : (I am happy to hear if I see something wrong)


    • SF8008 is able to capture low bitrates
    • You can input frequencies below 10.700 but if the combination with LNB LO brings the IF frequency out of tuner limits (950-2050 MHz) it does not work (I tested this by directly transitting in IF frequency from my adalm-pluto)
    • if you are using a normal LNB with 9750 IF, that means you can only input frequencies higher than 10.700 (9750+950)

    if you are using a normal LNB with 9360 IF, that means you can only input frequencies higher than 10.310 (9360+950)I am not able to find the way of inputting frequency of KHz steps (with dot... e.g. 10493.250)






    I checked the datasheet of RDA5815 and seems that it will work below 950 MHz.. so this is a software limit.. I started ompiling OPENATV from scratch to do the modifications to allow IF lower than 950 MHz (739MHz in our case) if somebody else not already started.




    I would like to know the discussions you know elsewher (forums, wb pages, etc.)




    Thanks
