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!
