Got my new NanoVNA-H4 today!

Charles Albert All Messages By This Member #15763 Holy cow! From the instant I opened the well-packaged device today, I was impressed. Very nice, professional box, fitted molded plastic tray to hold everything, no missing parts, and a thank-you note from the seller on eBay. On first inspection, I see only two things I might change... (1) I may get some foam and cut it to replace the molded plastic tray. I think that will provide better protection. (2) I will be somehow marking the SHORT, OPEN, and LOAD components to make them easier to identify. Maybe some color-coded Sharpie markers. My eyes aren't what they once were, and squinting to tell the three apart was a real pain. I've only "played" with the device so far using my 6m-70cm MFJ discone (it has an SMA connector on it) and everything seems pretty straight-forward. I do need to do a little playing to get the PC (running Linux Mint 20) to talk to the NanoVNA vie the USB port. I couldn't get it to connect, but I literally only plugged it in, saw it come up in the device list as a virtual COM port, and tried to connect with minicom. No luck on the few minutes I spent trying. Kept getting a permission denied error despite having myself in the dialout group.I'll have more time tomorrow to look at that. As I sat fooling around with the NanoVNA, I seem to recall devices some 40 years ago that could do nearly as much. They were, of course, the size of a small house and only countries could afford them! I feel confident in saying that I'm gonna love this gizmo! Take Care & 73 de KC6UFM Charles

Gyula Molnar All Messages By This Member #15781 Hi Charles, We are delighted and welcome among those who use NanoVNA. A lot of useful information has been discussed in this group, which you can gather in the "Wiki" and "Files" folders of the forum. If you’re more interested in narrative description, you can check out my web page. A small addition to your thanks: tell to the manufacturer rather than the seller. The above will prepare you for successful use. 73, Gyula HA3HZ -- * If you are not part of the solution, then you are the problem. ( ) *
Charles Albert All Messages By This Member #15898 I decided to give this a shot on a fresh install of Linux Mint 19.3 (Cinnamon) and made it to step #7.

This looks like something wasn't installed at an earlier step, but I am by no means a Python expert, so I really no clue of where to go from here. Any help from the real experts out there?
