The FA-VA5 was designed by DG5MK. The DG8SAQ software will speak to it however.
It is a very accurate instrument hampered by an abysmal user interface, That
said, in addition, I have an original N2PK, an upgraded SDR-Kits (DG8SAQ) with
S-parameter test set, an AA-55 Zoom, and an EU1KY VIA. Of all of these, the
FA-VA5 is the only one readable in sunlight.

4X6GP didn't say what he wanted the nanoVNA for, but if he didn't need 2-port
capability I would strongly recommend the FA-VA5 also designed by DG8SAQ. It
currently sells for about $190, is rated for up to 600 mHz. It works fine as
a standalone unit, but it will also work with a computer and SAQ's software
for some additional capability (like TDR).

I also own a nanoVNA and an older HF-CIA, but the FA-VA5 is my go to tool for
measuring just about anything (even resistors). For me, it has the right
combination of size, accuracy, and convenience. The output can be displayed
as either SWR or R +/- jX, and can be done so for either a single frequency or
as a graph across a frequency range.
