I plugged nanoVNA into a MacBook via USB 2.0 hub
and launched
from Chrome, after enabling its webUSB via the first Wiki link.
I suspect that nanoVNA behaves better via USB 2.0 than 3.0...
Web-Client behaves nicely on MacBook Chrome browser..

Chrome on iPad cannot load the Web-Client page,
and I cannot find any serial terminal console app for iOS
to test whether its USB connects to nanoVNA...

David,
It would interesting if you gave a review of the NanoVNA and NanoVNA-F since you own both devices. Especially interested in whether Rune's nanovna-saver app works out of the box with the NanoVNA-F.

Herb
================================

Herb,

With one brief test, 0.0.12 saver doesn't work with the v0.0.2 firmware. It appears to hang after a sweep is requested. I would be happy to work off-list with Rune to resolve this.

Cheers,
David

Daily Digest is what keeps me sane (?!)

C'mon folks - there is a NanoVNA-F group already on groups.io
Why re-invent the wheel?
I'm on it and the moderators should start telling people to use that forum for ALL -F related content.

'nuff said!

Hi David

I posted on this group as I know there is an interest in the larger screen
display - the unique feature of the -F variant. I am aware of the other
group. Perhaps it might actually be better if there were just one group,
as
90% or more of the discussions (firmware, PC software, calibration etc.)
are actually in common.

David,

I believe that the traffic on here is getting too much. I mentioned this a
few days ago. I believe others have made the same point. The subject of
subgroups had been discussed. Having the NanoVNA-F seems entirely sensible
to me.

Perhaps better still would have been a subgroup on here. Then anyone not
interested in the NanoVNA-F could just not subscribe.

Dave.

The -F, as I understand it, has a different microcontroller, a larger
screen (4.3"), a larger battery (5000mAh), and a built-in 16MB flash memory.

Also different OS (Operating System), so very incompatible firmware

Updated TAPR VNA sw
compatible with edy555 release 0.2.2 firmware with modified scan command

Wiki updated with pointer to firmware as well as TAPR VNA software

My understanding is that the RF components are the same in the "Vanilla"
and the -F version, and that they should both go to 1500 MHz with similarly
mixed results.

The -F, as I understand it, has a different microcontroller, a larger
screen (4.3"), a larger battery (5000mAh), and a built-in 16MB flash memory.

It seems to cost around 3-4 times as much.

David,
The meaning is the upper limit is 100 MHz higher than the 900 MHz of the NanoVNA-F.

Is the main (only?) difference in the -F that it has a 100 MHz higher

I am unsure if you made a typo or an error, but on the link to alliexpress,
it shows a marker at over 400 MHz. Did you mean 1000 MHz rather than 100
MHz?

Email direct, please, for the alpha testing :-)

Rune, do you want feedback here or via email?

Fair questions.

My use will be 99% lab use.
This means that form factor is not important. A display is nice but not critical, and if the display is less than 7" it is more or less useless to me. I have not seen the 4,5" NanoVNA. I have an OK sight for my age. I am actually contemplating taking a v.2 apart, and build it into a desktop solution e.g. with a 7" display, if possible. Adding some more optional buttons could be nice, e.g. for faster selection of certain measurements/features, up/down and select functionality.

For antenna measurement use I will probably pre-configure a palm size unit, since I find it cumbersome to operate. The toggle-switch is flimsy and the touch screen can be difficult to operate with dirty or cold fingers. Thus both are tough and risky to operate in a tower or on the roof.

If the component target cost is 100 USD making a modular design may not add a lot to the basic model. A modular design may in fact reduce the cost of the basic unit, since it may be nothing but the RF and processor modules. Then users may add a display of different size, provided the resolution is supported, battery and enclosure. I.e. a bit like the Yaesu FT-817 when it comes to the myriad of accessories (tuner, stands, back-pack, power supply etc.)

Calibration standards and TDR functionality apply in both cases.

You need to be connected to the Internet in order to use the Web interface because you need to access cho45's webpage.That means mobile data or WiFi.
All I did was to connect my nano to the tablet's USB host port and run cho45's webpage through Chrome and it worked.This was 3 weeks ago and the UI was flakey but cho45 has updated it since then so YMMV.
Regards,Larry

Normally, you really don't need to upgrade if the device is working well for you.
Typically, one would upgrade for two main reasons:
1. New functionality
2. Bug fixes

The latest edy555 release fixed 3 bugs per the github release notes, so you should probably upgrade to that version.
You don't need to use the extended frequency if you don't want to.
The device will still work normally for your needs after it is calibrated.

Cheers,
Larry

Do it the ISO 8000 way = spaces

I am presently running the 300_ch (9-11-19) version of the firmware because I use the NanoVNA primarily for HF. I see that the latest version is edy555_bugfix (10-1-19). Would it be a good idea to install the latest version even though I don't need the UHF function? In general, how does one decide which version to install?

I would like to try the software.
