Ah, grazie Maurizio! I suspected it had to be something I missed.. Saluti da sunny Melbourne, Australia.. lm

Hi Luigi , from message #7400 about the firmware version 4.0.3 AA QRP and Oristo wrote: "it has larger font, so it cannot show full frequency and measured value result and cut-off part of the value"

Would it be possilbe to have more store positions for settings? 9 would be great for HF bands. Does anyone now if the limitation is on the hardware or just on the firmwares available? George, SV3QUP

Hello again, earlier today I finally loaded hugen's v0.4.0-3, AA-4 traces ( NanoVNA-H_20191125_AA.dfu) FW on my nV... all looked good but when I went to set up and store the 5th calibrated range in

this maybe a oldie buts it is extremely powerful https://www.baudline.com/what_is_baudline.html

DL4YHF's "Spectrum Lab" (sound card data handler and spectrum analyzer) http://www.qsl.net/dl4yhf/spectra1.html looks a bit overwhelming at first, but it is really not that hard to use. It is very

Those well versed in the RF and microwave disciplines work with the 50-ohm impedance. Sure, the TV people work with 75-ohms, not much different. But for very high and low Z's, use the Smith Chart. It

You are not going to be able to improved reading of high impedance very much as the primary limitation is the 50 ohm impedance bridge and signal level differences get very small at the higher load

Don't forget about the free Android audio spectrum analyzer apps you can run on your phone or tablet.? They might even run on Chrome under arcwelder.? On Fri, 13 Dec 2019 at 5:16 PM, Bob Albert via

The applications (I've used more than one) that I've used in the past are pretty old by now, so I found this supposedly more recent list of free applications:

I will have to look around; do you have a link to a specific audio SA?? Basically I want it to measure distortion of an audtio oscillator. Bob

There are various free PC applications that use the sound card for an audio spectrum analyzer.? If you use a good quality sound card (flat response, low noise level) I would think that the results

It would be nice if someone would produce this unit for sale at a reasonable price.? An audio VNA would be great, as would be an audio SA.? I have use for the latter but it's not a common item. Bob

A couple more notes. The reference 3 for Z measurement is in the QEX article http://www.janbob.com/electron/AVNA1/Larkin-QEX-2018-May-Jun.pdf Also, there is a support group /g/AVNA1

It is a project, rather than an ebay buy, but http://www.janbob.com/electron/AVNA1/AVNA1.htm does a quality set of measurements from 10 Hz to 40 kHz. It is all open hardware and software. Note that at

Larry, Do we know if the clone bridges us the correct ferrites? I would stick with the transverters store version. < http://transverters-store.com/rf_bridge/rf_bridge.html> Order and active probe or
