    This is good but you still cannot read the small resistor values. That is all I am missing. Is there any way you could post a schematic?

    Nice looking filter unit,

    But this is a single filter design (this one for 10-12 meters) and won't be sufficient for the lower bands. If you want to use the amp for other bands, you will either need to change the components or use a multi filter board with a switching arrangement. If you look on eBay there is a Russian seller who is making a very nice multiband filter board. You could either use that, or design and make one yourself.

    73 and best of luck!

    Anche io ho acqistato il kit minipa200 e cerco di disegnare lo schema elettrico vedendo le piste ed i componenti del circuito stampato.
    E' difficoltoso montare l'amplficatore senza schema. E senza immagini dettagliate.
    Se quacuno hamontato il MINIPA200 per favore pubblichi immagini dettagliate dei componenti ed i loro valori

    I don't think he understands English.


    我需要从顶部的示意图或非常高分辨率的图片,将显示芯片电阻的价值。一个500万像素的图片我会想。但是手动或原理图会更好。甚至一个零件放置图。除了电阻,我有一切安置。任何帮助将不胜感激。

    I don't think he does either. Thanks for asking him in a language he might understand. I have most of it done but just have the resistors to put on.
