New on this forum dedicated to analyzers, I saw this article on an analyzer that seems "easy" to build with commercial components.
I don¡¯t know if this is still current, if something new exists, but in fact I like this modularity and simplicity of manufacture.?The area I¡¯m interested in is short-wave radio, so maximum frequencies of 50mhz.?So it¡¯s in the frequency band.
My questions: Have you already manufactured, are there any gerber files for the 434MHZ filter, etc, etc.
First technical question, I think you have to buy a filter or 2? (the filter photo is not clear)?like this?
Does the use of the app work the first time? (I¡¯m on W10).
Anyway, I¡¯m waiting for you to come back
