that's bad idea, because settings are stored in the program flash, which has large page size and limited write cycle limit. If you split trace settings and calibration data, it...

it seems that it's better to make reset after clearconfig, because some peoples trying to do saveconfig just after clearconfig, which leads to write wrong config back. I already seen...

Does it change frequency resolution? For example, there is needs to check high Q filters with 500-3000 Hz bandwidth. Does this improvement makes such measurement worse or not? In my...

I implemented custom scanraw command which performs measurement for unlimited point count and uses snprintf and it works great. It needs a little more deep stack size. The max stack...

If you're used rpi-update to update kernel version, it don't have kernel headers, so you will be unable to compile driver for such kernel. You can compile it for both...

regarding to LED 2, NanoVNA-Q disable it during sweep cycle to avoid noise: https://github.com/qrp73/NanoVNA-Q/releases so, there is no need to desolder something. You can just change firmware.

> Not really so. > The clock generator's inner PLLs are always locked also during the non scanning time. > So the perturbation on the integrators of those PLLs still...

You're seen it, because used firmware which uses LED blinking during sweep. NanoVNA-Q firmware disables LED during sweep and don't blink until the end of sweep.

> causing external interference to enter the power supply. According to my tests, this is not external interference. You can apply very clean external power (with no noise), but anyway...

I catch the issue related to this. I need to draw pixel perfect lines. But for some reason AddLine don't render last pixel, so it leads to incorrect image. I'm...
