Hi,
You have already been directed to the tintSA. You suggested that a spectrum analyzer that goes to 50 MHz would cover you for HF but consider that even the second harmonic of ten meters is close to 60 MHz and never mind about third harmonics, etc. That tinySA will do what you need? and probably cost you less than a home brew unit. I have two:) I abandoned my homebrew spectrum analyzer when the tinySA came out.
Best of luck to you with your projects.

Hello,
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 434mhz filter en vente - | eBay <>
Does the use of the app work the first time? (I¡¯m on W10).
Anyway, I¡¯m waiting for you to come back
