Yeah, I think my set allows 6 or 7 setting savings, and can recall them I remember in the menu. It seems a great idea. Putting on the tiny Open Short Load bits unto the SMA port and taking them out

Great info & advice. Thanks.

Thanks for the response guys. Please forgive me, as I am a little weak using linux. Can you elaborate more on how you got it to work? As mentioned it used to work until ubuntu upgraded itself (with my

The dfu tool and STMCube are interchangeable - Cube just has a lot more features (and runs on a lot more platforms). I have had zero issues using them interchangeable on my -H4 . . .

This gave me an idea. Does the reverse apply? If the manufacturer used STMCube, could I have successfully loaded an old NanoVNA dfu with DfuSE-Demo which ran with anomalies but then when I tried to

This is great !!!?Thank you my friend, for the files with full dump of GS-400 which is just what I needed. You're right, I destroyed the bootloader so I cannot use either NanoVNA-App or QTbut I

Jim I calibrate a coax pig tail that connects to my antenna system (50ft + UnUn + Wire + Counterpoise). That way, I eliminate a known good out of my measurement by “calibrating out” the known

Depending on your firmware version, you can save multiple sets of calibration data. I saved all five sets in my nano, specifically, 3 Mhz to 15 Mhz, 15 Mhz to 30 Mhz, 3 Mhz to 30 Mhz, 143 Mhz to 149

That depends on the level of accuracy you want. If you do a full range cal, and then set a narrower range for the measurement, it interpolates from the full range cal. That may or may not be great

Does it need new calibration every time when different frequency range is selected? Or is it enough just one initial full freq. calibration?

Read better.... You use STM-Cube, so you destroy bootloader (need use NanoVNA-App or QT for update in bootload mode) Upload this in 0x08000000 address as before 4-inch-GD32F303CCT6-20200619 FULL.bin

One of user made full dump for GS-400 I cut remove bootloader and data, try upload it (hold right button and power on, connect to PC, and use NanoVNA-App or QT for update) If not help you can try

This info was a great help to me, thank you!

I did pretty much the same thing..

The program simply works from the source directory without having to install it. The installation allows you to run the program from anywhere, just have the main program in the path and the modules in
