So it's not important to clear the memory? How to use? For other questions, what can you tell me?

Herb, there appears to be both a "NanoVNA-H V2" and a (completely unrelated) "NanoVNA 2" project. The latter project hasn't been very responsive to questions about who they are, and just seem to have

Or three... Fit a RCA/0.1" pins/BNC/SO239/SMA (depends what freq range and what is to hand) to either side of a pcb and the DUT (Device Under Test) in between. Even less than $6 probably assuming you

Thanks hwalker !! So the Hugen hardware schematics (https://github.com/hugen79/NanoVNA-H/blob/master/doc/Schematic_nanovna_3.3.1.png) *should* be that of the cards currently on the market? Diego

Where is it?

Rob, Your question was answered in the other topic where you asked it. Duplicating questions in different topics is bad etiquette. Herb

Pluto, Hugen retailed the first NanoVNA based on edy555's open source design. It is the hardware version that is currently being marketed by all NanoNA clone manufacturers. In response to a request

I would like to update my NanoVNA 2.8"TFT with the Gecko-logo, color whide. 1) Where I find the flash-program? 2) Which files should I use for to clean (Only DMR-CLEAR_MEMORY_DFU.dfu?)? 3) Which

Rob, The DMR-CLEAR_MEMORY_DFU.dfu writes "FF" to each memory location and is only used to clear memory prior to loading a new firmware. Larry has been kind enough to put all the current and past

Hello everyone ! Is there anyone who can clarify the hardware versions? To my knowledge, the first version is that of ttrftech (edy555) https://github.com/ttrftech/NanoVNA/tree/master/doc.

What files should I use? Only DMR-CLEAR_MEMORY_DFU.dfu ? Where I find the flash-program? I would like to go around my NanoVNA 2.8"TFT with the Gecko-logo, color whide. Info Hardware: Kernel: 4.0.0

Jim, Larry pulled his original PDF document in favor of this link, /g/nanovna-users/wiki/shellcommands . Herb

If you want to build a clone of the sdr-kits *Testboard*, and have no experience with the *2.54 mm round Female Pin Header Socket*, here a link to a cheap source: $ 1.33 for 5 x 40 pin sockets

Thanks Brian, It shows that you cannot arbitrarily use any sweep parameters, like what I did in my fist attempt (50K-300MHz). I'll be making more measurements... Paul

Thanks Larry, but I already mentioned in my post that I fully calibrated the VNA with the fixture attached.

What good does that do? Mike WY6K "... somewhere in the distance, there's a tower and a light, broadcastin' the resistance, through the rain and through the night..."

Larry, I can't find the Console Command pdf New name? Folder? Thanks, Jim, KA6TPR
