DiSlord,
I 'm happy you have been experimenting with variable points set. I hope after you receive your H4 you will be able to port the experimental variable point code to it.
The font size for the display menus had more density and stood out better on the March 31 beta. That is what I meant by larger font. I could make out the characters at a greater distance than I could on the April 1 beta. Some users might prefer the fonts used for the March 31 display menus.
I think you have been doing a great job with the beta firmware and wish I could buy you a beer.

How do I remove the screen cover sheet. Do I have to disassemble top cover?

I don't remember this being mentioned before:
When the S-A-A-2 (NanoVNA-V2) frequency is changed, it does a "self cal" using an open, short, and load on its Port 0 input switch. The result is not great, but it is not terrible for some purposes. It seems to do a pretty good job near the center of the Smith chart, but not so well at the edges. Other than the expected phase differences due to the different calibration plane, it works quite well from 20 MHz to 700 MHz. I assume that the "raw" data it reports over the USB port actually uses this self-cal.
My unit has firmware version git-20200229-aea0dc4.

Font size not change, change only some glyph like 'T', 'Y', 'V', 'M', 'K', 'R', 'C', '0', '3', '.', ':', ',' (and some small lile 'b', 'x', 'g', 'v')

DiSlord,
The larger AA fonts in the previous beta firmware version might be
preferable to some users. Perhaps that version could be the Nano-VNA-H4
antenna analyzer version, and the current beta version the default VNA
release.
All other changes appear to be working. What are your thoughts about
increasing the measurement points from 101 to a higher number in the future?
More points would not be backwards compatible to the NanoVNA-H, but would take
advantage of the larger flash memory and faster processor on the NanoVNA-H4.

John,
I used a hard shell plastic case with a foam liner that my $35 microphone came in.? I suspect, then,
that those cases are readily available cheap somewhere!

I have always used a Tee connector with the signal generator and the signal detector connected to the straight through connections, and the stub connected to the 90 degree angled connector. Just about any combination of signal generator and signal detector could be used, certainly including a NanoVNA. I have Tees here in several connector styles, including SMA, BNC, UHF, and probably others. I used to sweep stub filters with a Cushman communications monitor with spectrum analyzer and tracking generator, which had all BNC connectors as I recall. But I still used it for making RG-59 stubs with F connectors by using a BNC to F adapter on the stub. So long as the adapter is short and an insignificant portion of a wavelength at the desired frequency, it won't affect the measurement. I have also soldered cables together to make the Tee and stub and avoid the adapters.

Yes thats what I was thinking about...! Thanks for the headsup. One question before I flash it, fully compatible with nanovnasaver? Cheers!

[Suggestion] AA version display
Hello everyone, specially our developers.
Since we have an Antenna Analyzer version of our FW, can we have it more simple for field use?
Simple information like SWR, or at least lowest SWR, etc...
Some examples below.

Thanks DiSlord you are absolutely right , I added the? "d" and it's ok, sorry my fault.

Need use 'bandwidth'
You enter 'bandwith' lost 'd'
Use 'help' command for recive list of all supported commands

Re: Storing and transporting your NanoVNA
I've got mine in a belt-mounted digital camera soft-case with two compartments - one for the nano and the other for adapters and cables.
