Re: And Another Self Contained SNA

Really nice, Duwayne.  Not sure if I got that issue or not - I get four of every five ... when I realized I've missed an issue I pay my dues.

I haven't gotten into TFT and touch screens yet.  Coming soon to the WA5BDU workbench.

One similar gizmo I like a lot is from these guys:

Search for kit #25.  It's a VIA - includes the phase angle. cost me maybe $150 or so including the enclosure. Building is a bit of a challenge, and some things about the UI are not perfect, but I'm still pretty pleased with it. Don't ask me how it works - I don't know.

I have several posts on my blog about a self contained SNA-Jr that I built, similar to Tom's YANA..

They cover the very early design, and functionality I wanted to include in a small self contained unit I could use on the bench..  I have several versions of the Chinese SNA that is available on eBay for around $100, but they need to be connected to a PC. I have found that while working on a project, I usually grab the SNA-Jr.first

Like Tom's it has a small display, but I find it adequate for my use..  After I finish a couple projects I have going on, I plan on making a newer version with a larger display, getting the frequency range up to over 150 MHz., and adding a few other functions.  Latest update can be found at .For other entries just enter SNA jr in the search box on the top of the page. For those members of QRParci, I wrote an article about the SNA_Jr that was in  the July 2016 issue of QRP Quarterly.

For those who are interested, the sketch, schematic, and PCB files are located at

I also have the PCB files in the shared project area at if anyone would want to order a couple boards.   They are around $46 for 3 so if a several people want to get together and build one the price is reasonable.

I also have a blog entry with pictures of versions that other people have built and let me know about.
