NanoVNA-Q 0.4.4 released:


Added average mode which allows to reduce measurement noises.
Very useful for calibration.

OK, I see NanoVNA-F, NanoVNA-H, plain vanilla NanoVNA,
but who is NanoVNA-Q ?? Where did he come from ?

The good news is, there are 23 more letters available !!

NanoVNA-Q is alternative firmware for NanoVNA-H device

strange that you still didn't know that.
Some NanoVNA-Q fixes even used in NanoVNA-H firmware.

It has fixed frequency rounding errors, and multithreading issues.
Also it provides additional features, such as:
- improved gain control for NanoVNA-H devices
- better battery indicator
- vbat_offset command for battery voltage calibration
- color command for configure custom colors
- scanraw command for raw measurements with unlimited point count
- impedance label which shows complex impedance for current marker position
- more precise data transfer from NanoVNA to PC
- average mode which allows to perform more precise calibration and get less noisy measurements
- a couple of bug fixes and improvements

Also NanoVNA-Q firmware has si5351 status checking, so if there is a problem, you will see PLL indicator on the screen.
And also it allows to pause sweep and connect NanoVNA to PC and read paused sweep with no need to reset device.

Some of NanoVNA-Q features was added to NanoVNA-H_20191125.

Hello Dick,
