on the other end of the "scale" ..someone gifted me a HP Stream (2018 model) ...running Linux Mint 19.1 ..has more than 10 g freespace left on solid-state fixed drive (if you don't want to mess with

Setting power to 1 removed most of the noise and also the jump when switching to harmonics mode disappeared but it also resulted in yet another different oscillation pattern above 600MHz. For

Yes, there is a newer operating system available for your computer:? Linux.? Windows Vista is out of support and no longer updated, so, if you continue to use it, at a minimum you should keep it off

Rune, Yes, I did set the nanoVNA to non-TDR mode before making the readings. This is essential to getting good data in nanoVNA-Saver from the nanoVNA. I recalled cal0 which was created with my best

Has anyone tried it lately? YT9TP - Pedja could not calibrate over 310MHz on Oct 22 /g/nanovna-users/message/5510

Given custom NodeMcu/nRF5 firmware, nanoVNA need pass only 101x2x4 bytes of float per scan, which could then be converted to ASCII by BTLE micro for USB COM compatibility.

Hi, Maybe this in interesting for you: https://github.com/reald/NanoVNA 4 traces, big font, big info screen, 1500 Mhz, battery indicator https://github.com/hugen79/NanoVNA-H 2 traces (AA version), big

Dana, Indeed, and for that reason I measured the same cables with the same calibration kit on thee different VNA's. (one the nanoVNA) The results from the 3GHz VNA convinced me the fluctuations seen

Hi Erik; I was raised to believe that there is no such thing as a stupid question, but after several decades of not being exposed to the light, I discovered that there are actually many... All of them

nRF52832-QFAA/QFN48 has 64KB RAM + 512KB flash ESP8266 reportedly has > 40KB heap+data space available. I guess HC-05/6 is unbuffered but also not BTLE, so less interesting for e.g. Web Bluetooth API

I've tried NanoVNASaver v0.1.3 and v0.1.4 but they will not start. I get a DOS window with the error message: "Could not load the Qt platform plugin "Windows" in "" even though it was found. This

That is a lot of data to buffer. Firmware should sleep Bluetooth while sweeping and pause sweeps while Bluetooth is active.

Firmware should sleep Bluetooth while sweeping and pause sweeps while Bluetooth is active.

Before adding a radio transmitter and a second microcontroller such as a HC-05 to the NanoVNA, you may want to examine how much RFI it might introduce into the NanoVNA. My experience with my VNA,

RG-58 is just plain junk cable, and should never be used or (especially) trusted to yield meaningful results in any measurement situation. The center conductor flops around inside the shield at the

And here are the results. The first picture is with power level 3 when above 300MHz, second picture is with powerlevel is 0 for all frequencies. The noise is much higher with low power and that can be

I am a retired embedded processor engineer an can recommend the ESP32 programmed as a serial to bluetooth/WIFI adapter it is a 32 bit processor with the usual peripherals and both bluetooth and WiFi

Hi Rudi Super you are on the way now. I just did a T-Check for some N cal kit work presently working on and it was below 1 % all the way. That is the magic of 12 term error correction (actually 10

Sorry, I'm not following the group regularly. Is there any firmware with battery indicator, 1500 MHz and big font ?
