hugen@ one of those clones looks just like the real thing. Since we don't have the luxury of asking sellers to open up the case, perhaps you can tell us how to tell the difference by examining the photos, or just publish Maggie K's email address and let us buy them straight from her ?

Re: edy555 release 0.7.0-20200223-white screen
GREAT !!
I have it installed and I had no issues after the default (50K to 900M) calibration.
Remember to press the onscreen RESET button just prior to running a calibration on the unit.
You can save the cal to any location 0 through 4 .That will allow you to compare a few cal runs against each other.
Location 0 is the power-on default. Use that if you play with a specific freq band.
Just remember, the default firmware only grabs 101 cal samples, spread out over the freq span - and interpolates between them, which can be problematic.
Use the NanovnaSaver PC app to cal and scan as many points as you want for a given freq span.
Clear as mud?

=========================================================
I wondered what the symptom would be if someone accidentally installed the NanoVNA-H4 firmware on the NanoVNA-H, and I guess you answered that unintentionally. Fortunately, you had a NanoVNA without a case or you would have had to take it apart in order to access the pins for getting into DFU mode.
I suppose if the reverse occurred and firmware for the NanoVNA-H was installed on the NanoVNA-H4, similar symptoms would be experienced. Without the correct firmware, I'm not sure if you would still be able to get back into DFU mode on the NanoVNA-H4 by depressing the jog wheel switch while powering on. If not, opening the case to access the pins for getting into DFU mode would be necessary. Then again, getting into the DFU mode on the NanoVNA-H4 might be hardcoded in the OS and would work regardless.
Probably a question for hugen or erik to answer.

Hi Ari,
It's great you found your mistake.
So - it appears you flashed an H4 device with H firmware.
The H4 device uses an F303 micro whereas the H and older Nanovna all use the F072 micro.
They are NOT the same - they have different displays and interfaces.
In the future, please be sure to flash a device only with firmware designed for that specific device.
Now you get to play with it!
Please read the various user guides (there are several) on the forum WIKI and in the Files section.

Hi Gyula, Peace be upon You and Yours All.
"or reinstall the DfuSe demo." Your last words where the key.
I could revoke the device with jumper setting.
Then i saw my ignorance, i updated from NanoVNA-H_AA_20200118 to NanoVNA-H4_20200221 version.
Everything good in the End, Thanks for Your inspiration.
Thanks All.
Sincerely
** Ari **

Larry, I tried every combination of generate and file name for about an hour before looking for the DFU again and finding it uploaded. The hex file gave me an error but the bin file, in every case displayed that it was generated but I couldn¡¯t fine the file. I¡¯m familiar with all these tools as I¡¯ve programmed a number of STM32F4 and F7 boards using 3 or 4 IDEs. Thanks for the guide. I¡¯ve been in there a bunch.

Jerry,
I could never get a bin file to convert. It always produced a small output file.
Since you're new to this, please read my userguide...
/g/nanovna-users/files/NanoVNA-User-Guide-English-reformat-Jan-15-20.pdf
Look at page 28. Follow the instructions and when you click the Generate button, you will see a default value of *.dfu for a filename. Replace the * with the name you want.

Thanks for the reply.
I still have issues with SWR. After calibration, my 75 ohm standard is producing 82.4 ohms on the Nano. I have more exploring to do before posting about it.

Some of these changes look fairly nice - especially the fonts. I wonder if
Hugen will merge them into his firmware.

There is a part of the DfuSe Demo program called the DFU file manager. This will convert it from hex file to .dfu extension.
If you remember Larry has already uploaded the .dfu file here, you can download it here:

Re: Anyone had news from Maggie King?
I did not pay extra for shipping. I had that option but decided "slow boat" is fine as I have a NanoVNA small screen all ready. The option "Maggie" offered was DHL for +$10 but that was to the USA. I believe the included standard was China post.

Re: 1/4 wavelength coaxial trap for 440 MHz Ham Band
Test it as it will be used. Connect a "T" to the stub. connect Port 0 or 1
depending on which NanoVNA is being used to one side of the T. connect port
1 or 2 depending upon which NanoVNA. In other words do an S21 test. The
total length of the stub will also include and length of the T to the
center conductor of the pass though of the T.

show a high impedance. There is a high impedance visible with "resistance"

from 442 MHz. I cut the length of the coax in increments and am now at a
length of 2 1/2" (from the SNA connector to the shorted cable end). This
shows a high resistance at 375 MHz (peak at about 600 Ohm). Admitted
rookie, and doing this more to learn the nanovna functions than get a
working antenna (dual band J-pole). Suggestions on why 1/4 wavelength
shorted coax at 7.4 inches doesn't reflect a high input impedance around
442 MHz?

Re: 1/4 wavelength coaxial trap for 440 MHz Ham Band
Hi, Rob
Nice to see you here having fun with the nano. Amazing that it isn¡¯t even a year old. Changed your call, I see. I would have too with WA8UZC, I think. When I moved to Illinois, I had to get a new call as back then FCC didn¡¯t let you keep your call when you move out of call zone. WB9PMY.
