Why do you try the "exe" on a Linux system? - just follow my advice from below - open a terminal, go to a project or development directory and do this (maybe you need to install git: "sudo apt install

Hi, I guess its wine that has stopped working after the upgrade. Can you run any other Windows (exe) programs on your computer? (Something like LTSpice) Check the software center if wine is installed.

You most likely had a weird chip and firmware combo too. Take it as a learning experience. - know your hardware - make backups of firmware (ideally 2x & crc) - check if updates are compatible with

Yes.

that is still an older fw .. but at least you have a working unit with a working bootloader (so your pc should find it) dislord sure has a newer fw for it ... 17th (19th) of june 2020 is VERY old!

With DisLord's help I was able to unbrick it !!!!

GOTCHA! :-) what fw do you now have on what unit?? dg9bfc sigi Am 31.01.2023 um 02:38 schrieb Ray WW0AW via groups.io:

U N B R I C K E D !!! The problem was the STM32CubeProgrammer I got is buggy, so I switched to the older STLINK Utility and it worked like a charm. Thank you my friend.!!!

There is one particular use case where no calibration is needed at all, and that is when tuning a magnetic loop or similar antenna, where the only adjustment is resonant frequency. The S11 VSWR/log

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
