[Elecraft] OT: Nano VNA

[Louandzip]

 I got a nanoVAN V2 PLUS 4 about four months ago.  It's been FB.  Here's the site:
https://nanorfe.com/nanovna-v2.html
There are at least 4 or 5 different nanoVNA designs, V2, F2, H, H4, etc.. with a variety of firmware and software programs and versions floating around.... and even more clones of each.  Prices range from $50 to $200... The landscape is very complicated. You can go to groups.io, search on nanoVNA and find 8 groups to join.  I'm happy with what I got, but can't say if I'd be more or less happy with any of the others.

 The problem with that is it requires a computer and is apparently limited to Windows software. Nano VNA is self contained.
