Caught a real bargain on Amazon, a NanoVNA-H for about $40 after the $10-off coupon, even including the state sales tax. I’ve been thinking about acquiring one for quite a while … now I’m very happy that I didn’t buy the much older (and much more expensive!) one that I saw at a hamfest last year!
You can read online about people doing all kinds of measurements with these little instruments. We’ll see if it can shed any light on the high SWR that I have been seeing from the 20 meter vertical I use (see the previous post).
Looking at the menu structure I can see there will be a steep learning curve!
Or maybe not so much … the manual was my bedtime reading last night, and it seems to be pretty straightforward, at least for simple tasks like reading SWR.
The factory-stored calibration is for the whole range of 50 kHz to 900 mHz, so the next task will be doing a calibration for just the 20 meter band.
Well, really, the very first task will be taking a meter to the 3 calibration plugs to identify the Open and Short ones; I think the Load one is visibly different.
Here’s a link to a good introduction by Martin Svaco, 9A2JK: (printable .pdf)
I also purchased this ebook for my Kindle because it was only $2.99.
