Subject: Re: [nanovna-users] NanoVNA Saver

For those waiting for new binaries: I just published 0.0.11 :-)

This release brings averaging as a new feature: Press "Sweep settings" to
select between running a single sweep (of optionally multiple segments), a
continuous (live) sweeping of the range, or to average several sweeps from
the NanoVNA. You can configure how many averages to make, and optionally,
how many of the sample points to discard, based on which deviate the most
from the rest, and are least likely to contribute signal.

Also added is a new Resistance/Reactance chart, which shows both the R and
X component of R+jX. This brings the challenge of showing two traces for
the same data - added is therefore the option of picking a secondary colour
for sweeps under "Display settings".

There are further improvements to UI sizing, meaning the interface now fits
- tightly - on a 1366x768 screen, at least on Windows.

A few quality of live improvements made it in: Press escape in any of the
pop out windows to close them instantly. The calibration window now shows
more clearly when the source of calibration data is loading from a file,
and also the number of points loaded. A few crash bugs were fixed.

I look forward to hearing feedback from all of you!

I've been happily using the NanoVNA and various versions of "Saver" for

a lot

of projects lately, but some were just motivated by curiosity about the
device.

Unfortunately I have no other analyzer to compare to. In any case here

are

some sweeps from earlier tests that might be useful for reference or
amusement. In most cases, they were done with my very early attempts at

full

bandwidth calibration.

- The fm filter is a commercial product from the rtl-sdr.com people.

- The LW filter is a homebrewed design I use to augment VLF beacon

hunting.

- The multiband dipole is my 20ft high 80/40 meter trap dipole that has

been

augmented with parallel dipoles for 15 and 10. The feedline has a toroid
common mode filer.

- The 6 meter antenna is an attic mounted dipole with a toroid common

mode

filter.

I've also used happily used the device and "saver" to design and build a

6

meter "squalo", but forgot to save the files from the latest testing

run. I'm

currently working on a 400-700 mhz indor LPA design and plan to try to

use the

device for relative pattern and gain testing.

Earlier tests with several types of 500-900mhz 1/4 wave mag-mount

antennas and

TV rabbit ears showed useful relative gain results at 2-3 wavelength

spacings.
