Re: OneOfEleven V1.1.207 throws an error
Hi, Ignacio again.
Now the program throws this error from time to time after changing from single scan to continuous scan and back, but the error only happens randomly when clicking inside the graphics. But now the program does not freeze and it can be operated in the normal way.
Something remains that must be corrected.
Best regards,
Ignacio EB4APL

The first .ini that you sent works, the program fails upon reloading.
But the using the last one it works ok. I'm going to examine the current .ini file generated by the working program and compare it line by line with the failing one to see where is the problem.
Thank you very much for your support,

Ignacio,
try this ini file, although it is created by the program itself. For me, the program starts from the E: / NanoVNA-App folder.
Connect the NanoVNA to the USB, start the program, then 'Connected' and 'Single scan'. Once you've drawn a graph, you'll be logged in next time.

If you bought it from Amazon there is no hassle returning it. Drop off at Kohl¡¯s, Whole Foods, or fire return via UPS. Order a new one. I had one with white display got new one ASAP from Amazon.

I tried everything: deleting the .ini file, using one for a previous version etc., but no one worked.

Try some computer tricks: delete the old ini, move it to the root folder, and restart the machine.
This can still be the magic solution.

Thanks for info and time, removed cover but it did not affect imagined problem.? all? other performances great.? I can live with having to touch screen more than once,?? Not worth the hassle to send back to China via Amazon.? Joe

Hi Joe,
Okay, this is from the first production.
Be sure to remove the cover, because if the touch screen is pressed anywhere, it will not work properly.
Although other mistakes are possible, invisibly this should be done first. It is not easy to repair a device remotely, so we are just guessing about possible errors so far.
If the fault disappears after removing the cover, it is recommended to place a plastic washer on the screw towers of the plastic housing (4 pcs.).
If it still does not work, check the LCD flexible cord carefully for a break somewhere. The cord goes into a connector, there may be no normal contact.
Here you can find more information about possible errors in the forum. Use the 'Search' button.
When you remove the cover, try calibrating the touch screen. Be sure to mark the outermost points as possible and then save the status. If a touch screen error is found, replace it with the current one firmware, because larger screen applications work with them correctly.
Read more on my web page as well.
I am confident that the problem will be solved.
If there is no mechanical damage, these are repairable defects.

Re: OneOfEleven V1.1.207 throws an error
Strange - that didn't work for me.
I tried a brand new folder with the exe and also using my old ini file - keeps crashing every time I move the cursor to the graph area.
I'm in Win7 BTW.

Re: Increasing measurement range (ohms) ?
Old thread here (it was about the clones of transverters-store 3GHz RF bridges) .. I eventually got around to looking at these bridges.
I ended up with both a blue board and a green board, the latter with red sma caps. The transverters-store apparently ships red caps too, describes a green board but pictures a blue board.
The ones I got both performed badly and were identical. They appear to both have nearly correct coupler wiring : they do connect the core of the second coax(which is shown unconnected in the original site) to the outers. at both ends. Not sure if that matters. They also both had the 100R resistors incorrectly linked but a solder blob sorts that out, after which they behave roughly as I expect.
These were bought in 2019 at the time of that discussion so the situation may be different now. Given that the board only costs $18 from transverters-store.com I'd suggest getting it from there if you want one. I shall probably do that, though I've got some more traditional N-type metal bodied directional couplers on the way.
There's a seller with a large number of the 100kHz - 3GHz Hameg bridges that were built for my HMS-X SA at the moment. Unfortunately he wants ?600 each for them. Which I think is cheaper than Hameg sold them but still out of budget by at least 10dB.
A green (not blue) ~US$10 reflection bridge
e.g. from eBay
with matched SMA references (want a matched pair to calibrate nanoVNA CH1)
Why is a green reflection bridge better than a blue one ?
(Presumably it's not just a matter of preferred colour ..)
Blue are bad clones of transverters-store design and are wired wrong.

You need to delete the older 'NanoVNA-App.ini' file and then start .exe to create a new .ini file.

Hello Royce,
have You following programs:
1. DfuSeDemo
2. NanoVNA-APP 1.1.206 ?
look at the picture:
on the left are the contacts for reboot:
1. have you driver already installed?
Program DfuSeDemo 3.0.6 have driver for Windows 7, 8, 10
2. short-circuit these contacts - with tweezers or scissors
3. start DFuSeDemo for fw update
... its not end

Hi Vladimir,
I have the nanovna-h...........the only way to get to the dvy mode is to do
from list....i did all the steps to update the firmware, but when I
disconnected the nanovna-h from the pc, and turned off then back on.....
the screen is white now...before it was black. if it is in dfu mode now,
then what was it before? and now it is not recognized by pc or software,
etc... how do i get it back to factory settings, etc.?
thanks.
Royce

Re: Comparison Testing of Three Ferrite Beads using the Smith Chart
Thanks pjzzz, Dave, and Jim for the additional replies.
I've been studying ferrites now for several weeks and am amazed at the amount of information available. The Fair-Rite Products website has a lot of information including articles, calculators, and videos. There are also many other websites with a great deal of information. I'll also mention that the ARRL Handbook has an excellent section on ferrites with quite a few charts.
Thanks Jim for the note on the coax shield and bulkhead in the IC-706MKIIg. I only learned about the ferrite solution recently. ICOM's approach seems to be the use of many spring ground clips that make contact with the chassis or cover. Unfortunately, those connections often need maintenance over time.
I currently have two Fair-Rite Mix 43 beads (2643801102) on the small coax cable from the Filter Board where it connects to the Main Board. The chart on the datasheet shows an impedance of approximately 27 ohms at 20 MHz. That would be 54 ohms for two beads. It would be interesting to understand the actual problem and where design changes are really needed. Your solution may very well be a better approach.
I just noticed that the chart on the Fair-Rite datasheet confirms my Smith Chart test of the Mix 43 bead at 2 MHz. The chart for one turn at 2 MHz shows an impedance of approximately 6 ohms with a resistive component of a little less than 1 ohm. My test data with the 2" wire showed 759 milliohms and 495 nH. That translates to 0.759 + j6.2 ohms at 2 MHz.

Thanks for the response.... however...when I connect to the PC it's not
recognized by the PC or the progaming software..... also when the nanovna-h
is in gfu mode, the screen is black...... not white?....any other thoughts,
etc.
Tnx,

do what is described.
As long as the screen is white, your device is in dfu mode.
(of course, if you didn't drop it and there is a hardware reason)
