  1. So, this LNB is built around a very cool channel stacking ASIC from MaxLinear, the MXL862.
    But as there is no public documentation, I cannot control it.
    So I had to resort to other measures.

  3. Cambié preventivamente los #LNB de banda Ku para las parabólicas que tengo en el techo para recibir el satélite #ARSAT-2.
    Conseguí la misma marca #HiMonde. No son la gran cosa, pero los anteriores no me dieron problema, cumplieron 15 años y seguían tirando. Recomiendo.

  7. Et hop, 2e victoire à la maison. Et encore face à une équipe qui ne réussissait pas au CSP depuis des années. ☺️

  14. @thebaldgeek I am betting you got a PLL #cband #LNB and it is sensitive to the cold. This has been a problem with these LNB's for a long time, as you can see from this article from 2016:

    Are phase-locked loop (PLL) LNB’s a good idea?

    (Note the last EDIT down near the bottom of the article).

    I don't know how cold it gets where you are but I suspect you are going to have issues during any cold weather event. In theory you could attach some kind of heating element, like a small reptile tank heater (make sure it's waterproof) and turn it on a few minutes before you want to watch TV but IMHO those things are just poorly designed, even if they are being marketed as a solution for 5G interference.

  16. Glad to say that we got a good result from the heated #LNB
    overnight. No drop in the data rate with the cooler overnight temperatures.
    I will run it for another 2 nights with the rough bubble wrap over the telescope heater band. If it works each night, then I know I found the root issue and can make a better cover and put a temperature sensor in there and automate the control side.

    This, I think, is a great example of why this stuff is so fun, you just never know what's going to come at you!

  17. Pulling my hair out of late (wait, Im bald!).
    I swapped the #LNB on the #cband dish because I was getting, what I suspect is #5G interference for an #LNB that has a filter.
    Turns out the new LNB is a bit of delicate snowflake and is unhappy outside of a very small temperature range.
    I have already done the #GPSDO modification, so its not that.
    Long story short, I thought it was a tracking issue for a good while, but now working on getting a stable temperature range for it.
