Hi John, This sounds like a really nice idea! I do have a SDR-Kits VNA 3SE, but I won't offer to lend it to you since I am in Sweden. However, I am interested in following the procedures and results

Hi Gyula, I hadn't seen those references before ... a bit complex for me ... I have seen some of 'joeqsmith' stuff before. My interest is in making sure that I am using this tool (ie nanoVNA)

The SDR-Kits software is more refined.? Their calibration kits are of higher mechanical and electrical quality. I use it for things like sorting crystals for ladder crystal filters and LF/HF tasks. I

Thanks Larry and Richard for the help. It looks like my NanoVNA-H4 is operating normally although the battery LED only flashes when the voltage is very low. The battery LED is Blue on my NanoVNA-H4

I'm as interested as anyone else who might have one to know the accuracy and reliability of these affordable VNA's, whether nano- or the one from SDR-Kits. I have a variety of VNA's available but am

Kent, I haven't opened my 1 year old H4 lately but the led flashes when charging and is on steady once there is a full charge. Pulling the usb cable extinguishes the light.? ... Larry On Fri., 25

My NanoVNA-H4 has a FM5324B for the battery charger and 5 volt boost converter circuit. The schematic shows a FM5401. Does anyone know the difference? The datasheet is not written in English. I'm

Thanks to all.? I will go start layout something in Kicad based on QUCS or Ansoft. Thank, Jimn8qoh On Thu, Jun 24, 2021 at 2:29 PM, Dave WB6DHW<dave@...> wrote: Zack: ? KICAD is free and will

Thanks to all, especially DaveD, Clyde and W0LEV. I have joined the "-F" group but will reply here for continuity. I am still learning but the F group has given me some specific insights (serial

Hi Ian, Use the terminal mark to attach an image. (Add Attachments) You can find several topics about crystal and filter measurements on the eevblog. For example:

I have the same nanovna F from Deepelec that for sure is a great instrument for my mobile HF operations. So, if I've well understood, with latest firmware upgrade the sweep steps increase from 101 to

Hi, I scanned several filters and crystals today. I got an occasional Error message as follows .... "Access violation at address 005173DD in module 'NanoVNA-App.exe'. Read of address 00000CD8." Each

I have the Deepelec NanoVNA-F, hardware v3.1 (with discreet buttons instead of rocker switch). I've been impressed by it so far. I like the shielded metal casing and extra large battery. I haven't

Hello Richard! FW Version of NanoVNA can You see so: CONFIG-->VERSION 73 de Vladimir, dl7pga

Richard, All the original nanovna, h and h4 units will do TDR.? How are you trying to flash new FW?? Are you using the defuse utility? If yes, get my modified exe file from the forum's file area and

Hi N7WFK, Try taking a video of the screen using your cell phone at turn on time. Then you can go back to the still frame that captured the screen with the version info. John, WA3JRS

I agree that the DEEPELEC NanoVNA-F is the best out there, but if you have a small screen NanoVNA-H, the firmware can be upgraded to "1.0.45" with the larger and much more eye friendly font. The
