I am a rank beginner in this. I just got my first VNA and it has the following firmware installed: ch> info Kernel: 4.0.0 Compiler: GCC 8.2.1 20181213 (release) [gcc-8-branch revision 267074] Architecture: ARMv6-M Core Variant: Cortex-M0 Port Info: Preemption through NMI Platform: STM32F072xB Entry Level Medium Density devices Board: NanoVNA-H Build time: Oct 18 2019 - 16:10:54 I went to the sites to find what to install, and there are bunches of choices. I need to know what to use, and how to actually use the STM32 to do the job. Most of the instructions I have found are for the DFU programmer that is no longer available. Who out there has the patience to enlighten a newbe? Thanks!

what is the way to set the marker freq? tnx dave k7da

Hi all I recently bought this unit from DXEngineering. All documentation (ha ha) points to [ https://www.sysjoint.com/ | https://www.sysjoint.com/ ] Having issues trying to use NanoVNA-App.exe and ingeneral getting started. Did I get a "pig in a Poke" or is the unit something I can work with after I beat the learning curve? Any help will be appreciated! 73 Wayne N0POH

Is the Smith chart in NanoSaver be able to show also the admittane circles in addition to the impedance circles?

Hi "Anything that can go wrong will go wrong." (and at the worst possible time) Just before going to sleep, an idea came to my mind. I think it is better to leave to install Ls, Cs, Ds, (even the transistors), wind the Toroids after we make sure the digital part of the transceiver works. Why? imagine you install everything and power up and you made a mistake and have the smoke If some thing serious, what a waste :( Make sure your firmware loads, up and running then install Ls, Cs, Ds, transistors, wind the Toroids vs Just an idea 73 DE muhsin TA1MHS

Hello everyone, I've recently bought a NanoVNA V2 Plus4 , and was trying to change the IF bandwidth (IFBW) to get a bit less of noise. Is there any way to do so with firmwares, laptop softwares or so? By default the device only lets me use 6.3kHz and has no other options, but on their website they post measurements made at 0.8Khz of IFBW... I'm running the latest firmware available on NanoRFE website. Thanks!

Hello everyone. I've just bough a NanoVNA V2 plus4 from Amazon and was interested in flashing the Ojisan firmware. After flashing via normal procedure as written in Nanorfe website, the VNA stays with the white screen on. Even after reboot. I've tried multiple firmwares from Ojisan and looked around for people confirming them to work on my hardware version, but can't find a solution. Do I need to change the flashing procedure? Am I getting something wrong? Thank you so much in advance!

How long does it take to charge the battery....if not quite dead ? Does it trickle charge once charged up ??
