Micro SDCard slot for my NanoVNA H4
Category: General
Posted by: lex

When I got my hands on a used NanoVNA H4 I couldn't resist looking inside to see if it was using shielding for the RF components. Turned out it did so I bought the right one. But one thing I noticed was the component silkscreen for a micro SD-card slot without the slot it self and because it still contained the original software which didn't mention anything about saving images to SD cards, I didn't do anything with it.  

Until now . . . (continue reading)

Got my QCXmini kit from QRPLabs and finished it. So I added a complete building report (incl designs for the tilt-feet) on this page.

QRP-Labs filter adapter for the NanoVNA H4
Category: General
Posted by: lex

A few owners of the new NanoVNA H4 have requested me if I could re-design the PCB so male SMA edge connectors can be used to directly connect the adapter PCB to the NanoVNA H4.  For a while I holded it off, but recently I got my hands on a used NanoVNA H4 which I'm very happy with because of the bigger screen (yes my eyes aren't getting better). I started to use the H4 and wanted a dedicated adapter for it. So I measured  my NanoVNA H4 and it has a distance of  39.5mm and comments from other OM's indicate that it's quite constant +- 0.1mm. 

So I made a copy of the original design and changed the board layout to fit our needs.

Tools and parts

For me Hamradio and modelrailroading is all about building stuff. For that you need tools. More often you need Lots of tools (listing of tools I use).

And sometimes for building stuff you need to build tools and parts. On this page I post building reports of DIY tools and parts I used for my hobby.
