Donated, thanks for the service.

No, jog wheel does not move anything in the drop downs, but yesterday it did move the cursor horizontally. I have tried to re-calibrate the touchscreen. Although, I'm not sure that helps with

No, a firmware update probably will not help with this (but it would give you lots of other updates and features). Can you get to the menu items properly using the jog wheel? First try to re-calibrate

I'm having great difficulty navigating between drop downs on my NanoVNA-H 4 edy555 design version 0.5.0. First thing, I thought the first, 'about screen' disappeared after a short time, mine doesn't.

Hi All If it is really worth to replace the Chinese MS5351 by the Silicon SI5351a in my H4 SEESII Hardware 4.3_MS . Thanks 73's Nizar

All, It's that time of year again when we need to pay the annual $220 fee to keep the group going. The payment is due? the 18th and will be automatically paid by me. Once again I ask that anyone who

Thanks for the schematic. // HIRO, JJ1FXF

Order new H4 or you can install slot as on new devices and use last firmware https://github.com/hugen79/NanoVNA-H/blob/master/doc/Schematic_nanovna_H_REV3_6_1.pdf

Thanks for your reply, DiSlord-san. My 2.8” NanoVNA-H is without microSD card slot. Or any mod to add the one? // HIRO, JJ1FXF

You can use unlimited calibration slots if save/load on SD card.

Hi, all. I'm HIRO, JJ1FXF and I just joined this group today cause I'm also looking for some simple menu firmware of my NanoVNA-H. Since the 2.8" screen is becoming too small for my age, so I will

You can set the frequency to output on one frequency but you can’t set the level. It is much higher than -73 dBm so you need attenuators and a way to measure that level so you can adjust the

The Tiny SA Ultra has this ability, to generate a signal on a precise frequency, at a very precise, calibrated level. Use that. -- Rich [email protected]> wrote:

Hello I am looking to use my H4 to generate a signal on HF at -73db and -70db to do some calibrations after a firmware update on a my receiver. Some Nanovna have a tab called "Signal Generator" but

hmm .. i own a v2 (saa2n) and a v2plus4 and have made over a dozen fw upgrades on each but but NEVER used a programmer!! connect to usb, switch on with button pressed and voila its in upload mode ...

Many YouTube vids on the Smith Chart and tutorial PDFs are available also. Have a look. A few hours and you'll know how to use the chart...

Great answer... Roger

Maybe I misinterpreted his intention. I thought he was going to mount the (indoor tuner with protection) at the antenna base and manually adjust recorded settings as he desired. Sorry about my

Since the OP wanted to make antenna matching circuits that are remotely switched, he should measure the antenna impedance at the desired frequencies with the nanovna then synthesize matching networks
