My NanoVNA-F arrived today and I'm looking forward to playing with it. It's slightly smaller than a Google Pixel 3 phone (which isn't the biggest model), although somewhat thicker of course.

UK buyers might like to know that it escaped duty, tax, collection fee etc.

Cheers,
David

My NanoVNA-F arrived today

Since NanoVNA-F has its own group, GitHub and videos,
while this group is already quit busy,
[with too many messages lacking clear context
and/or generous with redundant content]
please consider further discussion NanoVNA-F only there:
/g/nanovna-f

Hi David
Can you please post a link to where you got it from,
Thanks Dave 2E0DMB

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.

Are the main (only?) differences in the -F that it has a 100 MHz higher upper frequency limit and a bigger display?

Hi John AE5X -

Are the main (only?) differences in the -F that it has a 100 MHz higher upper
frequency limit and a bigger display?

No, it has an incompatible processor that may support more/different functionality.
Please check out and/or /g/nanovna-f

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.

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?

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

Herb

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.

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

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.

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!

================================

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

Yes, what Herb said!

"... somewhere in the distance, there's a tower and a light, broadcastin' the resistance, through the rain and through the night..."

Yes, please.? Do not contemplate a second -F group!

Hi David,
Without a NanoVNA-F to test against, I don't know that I would be able to
do much to support it. But looking at the source code for the firmware, it
shouldn't be too far from what the regular NanoVNA does.

If you use "-d" as a command line parameter, you get debugging information
from NanoVNA-Saver, and you can see what it's doing when it stops
responding in the console.

Thanks for offering to try, though! :-)

Thanks for the info,

David,
The NanoVNA-F developers announced a few days back that the command set for the NanoVNA-F overlapped the NanoVNA and; therefore, should run nanovna-saver with only small changes to the code. Rune, inquired about the nature of the code changes and they kind of backed off. At this point they are delivering a product without a document describing the command set (unless you want to dig through the C code) or a software application for capturing the data measurements. The device does come with a sandisk card, but I haven't seen any info about what the user can save to it. I hope to start seeing more info from early adopters such as yourself.

Herb

the command set for the NanoVNA-F overlapped the NanoVNA

I call BS on that, based on a long career in embedded software development.

If NanoVNA-F wants Rune's support,
then they should AT LEAST provide him one, FREE.
