I have recently bought a NanoVNA-F V2 Portable to replace my miniVNA - originally marketed by miniRadio Solutions (Mrs).
The latter was supported by Dietmar Krause DL2SBA for many years. However, he recently gave up his role of development and support for this range of VNAs via his website dl2sba.com. It is now no longer possible to download the software for the miniVNA from this site, although I still have the most recent upgrade on my PC. This VNA was a useful piece of equipment with a variety of different graphical outputs and was easy to use.
In the past, the following website has proved useful with the miniVNA in determining the characteristics of impedance of ferrite and iron-powder cores, filters and coils etc. I expect it could also be used with the NanoVNA, although I have not tried it out:

Whereas the miniVNA covered analysis from 0.1 to 180MHz, the NanoVNA-F V2, supplied by SYSJOINT Information Technology Co. Ltd. covers 50kHz to 3GHz.
There is a user group: NanoVNA V2 Forum and you can download the manual here: 
This is as much as I can say at the moment, until I have spent more time using it. Hopefully other people will come along and share their experiences.
Regards

Not sure it warrants an award, but it's nice to know that a server-side script out there somewhere knows that I'm still alive!

Phil G4UDU mentioned this a couple of days ago, and I thought I'd take a quick look. It's the RSGB Transatlantic Centenary Tests, staged to commemorate the first transatlantic amateur radio signal - between Wandsworth and North America using (G)5WS.
It's annoyingly addictive in a masochistic kind of way, and it's particularly twisted in that as far as a transatlantic test celebration, it involves us as GB stations trying NOT to get across the Atlantic, but to hit-up all the (original, renewed) GB station callsigns involved in the very first tests.
You can view the leaderboard, and search for callsigns here: https://clublog.org/charts/transatlantic100.php
Of the MSARS members I can find, Phil is in the lead with 34, I'm second with 9, and Ken is still in the running with 2.
Yeah, I know, but I'm kind of poking you with a stick here. Can you beat 2? Well CAN you?

Ron is a longstanding friend of the society, and if you listen in to the lunchtime nets, you will be aware that he has been having terrible trouble with his landline provider TalkTalk.
Unbelievably, he has been without landline phone and broadband since November 3rd, along with a good few of his immediate neighbours. That's FIVE WEEKS!
Without getting into too many details, it looks like a clumsy excavator operator has torn through a bunch of Openreach cables in the street, but TalkTalk have failed to provide him with any alternative means of communication, even though he is a vulnerable senior gentleman living alone - and I'm sure he won't mind me describing him as such.
I'm pursuing various means to apply pressure to said company (who have behaved despicably in my opinion), but what I'm asking of society members or indeed any local member of the public, is if they have a redundant 4G/LTE router which they could lend to Ron to get him back in contact with his friends and family in the short term. We will obviously provide the SIM card.
Update
Whether it was anything to do with my lobbying those with influence or not, but I'm happy to report that Ron has now been reconnected with the rest of the world, and I can tell you that he is mightily relieved. Many thanks to the office of our MP, Mims Davies, and in particular to Sarah, her Chief Officer for their efforts.
I'll leave this article up here as a warning to other potential TalkTalk customers, and because it took me ages to Photoshop that image.
