Orrin 0.7.3 appears to be the latest, released last week https://github.com/NanoVNA-Saver/nanovna-saver/releases/tag/v0.7.3 Is working ok on both my win 10 and win 11 machines Good

Nah, not even remotely a possibility. One of the three machines is a server-class box that doesn't have a battery (other than the CMOS backup cell). Kind of got it down to changes in the kernel

VK2KKZ de WN1Z Phil, that's good news, a clone is unlikely. The 'RUNING' typo is also visible on the Sysjoint SV4401A io.groups announcement of 0.5.9 firmware. I posted over there that i found

Orrin This post mentions that "firmware of SV4401A is encrypted, we have not found a cloned SV4401A so far on the market" https://sysjoint.groups.io/g/main/topic/sv4401a_clones/104681340 Mine also

Why do you say that ? Can't find the extensible antenna anyway.

I would not say that. Aside from measuring a monopole + cable and not just a monopole, it is not only loaded but also 27 cm long (17 cm for 433 MHz). Probably in order to present a good match to the

None of these antennas are really any good at HF frequencies and certainly NOT down too 100 kHz. Sure, any hunk of conductor will capture "something". But only the one on the right is acceptable for

Sounds quite low. A monopole against a ground plane will be in the 25-35 ohm range. That one is obviously center loaded, but perhaps not for 433 MHz (more likely cell band at 850). Did you also get

Whoops! https://www.nooelec.com/store/nesdr-smart.html (first picture, antenna is on the left)

Clyde, thanks for that info. The SV4401A group. Just what i need. Best 73 Orrin WN1Z (clyde.lambert@...) escribió:

Hi, i am trying to get a grip on using the nanoVNA. Does anybody have the 433 MHz antenna + base from the RTL-SDR kit ? Firstly calibrated at device port (no cable), then measured the loaded

Linux probably thinks the device is pulling too much power. I'd ensure that the battery is fully charged. See https://paulphilippov.com/articles/how-to-fix-device-not-accepting-address-error for a

I have tried searching the group.io archive and got nowhere. Hopefully this is a new problem, and I didn't just miss it. I flashed this H4 just over 2 years ago (Feb 2023) to version 1.2.19 using

Hello, There is a groups.io group you need to go to. SV4401A: https://sysjoint.groups.io/g/sv4401a It is the correct group for your version of a NanoVNA. It is a different design than most of the

Well NanoVNA Saver 0.6.5 used to connect to com port on Win 10 and now it does not. I start the nanovna software, turn on the NanoVNA and when I click Rescan the software crashes off. If I turn on

At the advice of many, I simply removed the 9:1 UNUN (Palomar Engineering) and made a "direct" connection to the rain gutter via a sheet metal screw. Then ran one radial along the ground (I will try
