Hi Erik I seems you have made some error correction one way or the other. The S11 ImagZ in the first image attached is inductive as it should be and nicely straight up to 300MHz. You also see the S11

Hello, I've got a question. I have a Celwave duplexfilter for UHF. I tuned it for 7,6MHz spacing. Tuning is done with the nanoVNA and patience. But... I discovered something strange. The antennaport

I just found an Android USB terminal app that works with the nanoVNA on my tablet.? https://play.google.com/store/apps/details?id=de.kai_morich.serial_usb_terminal? ? I've attached a screenshot.

Hi Rudi Maybe one of these days I will proof it is hopeless ? Kind regards Kurt -----Oprindelig meddelelse----- Fra: [email protected] <[email protected]> P? vegne af reuterr@...

The Android app has JavaScript ported from the web app, using Capacitor https://capacitor.ionicframework.com/docs/android/ .. which requires at least Android version 7.0 on API 24 to use the Android

Hello Erik, I have seen your post too late, to include it in my post for Kurt. It makes me happy to see, that you came to the same conclusion like me :-) 73, Rudi DL5FA

Here my latest T-check measurement with nanoVNA firmware adapted for better measurement performance and a 10dB attenuator directly after the Tee (calibrated out in the thru calibration) The small jump

Hello Kurt, Thank you very much for your recommendations, but I did not make any progress today, so I give up. I think the problem is in the CH1 bridge impedance, and I do no longer want to try to

Hi Jos, Grab a copy of the Console Commands document. It now has a section at the end that lists and links to the major firmware developers for the NanoVNA.?? Go to any of the GitHub locations and

One problem with the nanoVNA is the far from perfect match of port 2. If you measure the tee with two 50 ohm loads the S11 is a nice line tracking the 25 ohm curve upwards Once you replace one of the

Did you download this? https://github.com/ttrftech/NanoVNA/releases/download/0.4.0/nanovna-firmware-0.4.0.zip

Hi Folks, My name is Jos and I am new here and looking for the best firmware for my NanoVNA device. I am using my NanoVNA with the "NanoVNA-Saver" sofware and had problems with downward lines in the

Should be fixed now. Please test. 73 DE DL9CAT

Hi Daniel, partialy true... ILI 9486/9488 have different key commands compared to 9341. Both does support 16bit pixel data but via parallel interface, via native SPI you can only use a strange 8 bit

In newer firmware, use shell command `threshold`, followed by `saveconfig` /g/nanovna-users/files/NanoVNA_Console_Commands_Nov-4-19.pdf

Datasheet for the si5351 says it works up to 225 MHz. The original Nano VNA firmware pushed it up to 300 MHz, which has proven to be a wee bit too far. Above 300 MHz it used the third (and fifth)

Hi Rudi Great.. Well you are on your way. I see there is still a small problem as you have not calibrated so the female female adaptor is subtracted during the Thru calibration. When everything is

it's hard to say something, because there is not enough data on the screen and screen quality is very bad, because this is not screenshot, this is photo. You can get real screenshot with NanoVNA MOD

Hello, A friend of mine has just received a new NanoVNA-H bought from an ebay seller in Essex. It's one of the cased units with black front and all accessories very nicely presented in a box and even
