Re: NanoVNA Under The Covers
Excellent review, Gary. The small PCB on the battery is the protection circuit. The charging circuit is located just below the jog switch and is a combined LiIon charger and 5v inverter. Lastly,

Re: NanoVNA Under The Covers
Thanks Gary. I contacted my supplier, EBay and ask if I could get another set of cal8bration loads.? No luck. The 50 ohm was of very high quality, return loss -70dB compared to -40dB from another

NanoVNA Under The Covers
Having expressed accolades to AliExpress supplier Guangyi0016 store... I felt duty bound to provide a thorough overview of the hardware itself. I also think I missed the "i" in the supplier's ID, so I

AliExpress and NanoVNA supplier get 5 stars
I received my NanoVNA today... just 22 days after ordering it. FWIW, I made the purchase via the AliExpress App, and the supplier was the same as used by at least two others with similar delivery

Re: VNA S/W & H/W project & theory resources
Having a central repository for files and possibly links is way better than telling people to search all posts for "something discussing what I think was screws" but which actually referenced

Re: VNA S/W & H/W project & theory resources
Thanks, I'll have a look. I want to be careful not to increase the 'noise' with a pile of links but at the same time, search for and post some really useful ones, IMHO. 73 Larry VE3LRI

Re: VNA S/W & H/W project & theory resources
I took the liberty of creating a page for external links. I don't have my nanoVNA yet, so I don't have anything to add to... well, to any discussion except this: The idea of a wiki is that anyone can

Re: DL2SBA j-vna software
The NanoVNA USB port was originally designed as a debug interface, according to the original designer (edy555). Since he open-sourced the code, maybe others will add additional functionality. The only

Re: DL2SBA j-vna software
IMO, nanoVNA should instead at least optionally emulate USB interfaces of better-supported VNAs.

I have asked Dietmar (DL2SBA) and he is not interested in making any changes to his code to facilitate the NanoVNA. / Gerry

Not necessarily more costly. I have homebrewed the F4GOH Arduino based vna for HF only and it uses that interface. Works well but only up to 60MHz.Sent from my Samsung Galaxy smartphone.

Alternative VNA software
Dave (G8KBB) has evolved a most wonderfully robust VNA GUI that he calls myVNA. I believe he is open to sharing the interface with those who might be willing to do the work of adding support for other
