Somewhere in England (possibly?)!
Just received the Feb issue of "Radio User" mag, and read the 2nd (the 1st was in the Jan issue, and more to follow) of Keith Rawlings' articles on the above - a very interesting piece of kit and relatively very cheap (around £60 to £100 on Amazon) for units that appear to be able make relatively precise measurements from 5-kHz up to 3GHz+ (the upper limit varies according to the specific model).

Worth keeping an eye if you are on the loookout for something like this (might well buy one myself in the near future).

NB: Keith Rawlings's articles also include weblinks for quite a number of websites with useful info on these devices and how they can be used.

A little less analogue, and a lot more crap.

The cheaper (under £25) version is being peddled on Ebay that claims a range of 50kHz to 900MHz, though it might be just a software upgrade that is needed.

NanoVNA 900MHz upper limit can supposedly can be updated to 1.5GHz with reduced performance.
NanoVNA V2 has a 3GHz+ upper limit. Though it is called the V2 it has nothing to do with the NanoVNA's original designer and is a separate product.
