Hello Piero, I was using NanoVNA H firmware, 1.0.39.dfu FW and nanovna-saver 0.3.8 This combo did not work. I could not get the Software to recognize the VNA no mater what I tried. Even though the FW

Hello, Tell me if you have checked the SOL terminations on another VNA? Also, I found that I needed a warm and fuzzy check when using the VNA so built up a couple reactive terminations. That is, a PCB

Powers up, but nothing but a white backlite screen????

If it were mine, I would almost certainly try to repair it. Probably burned up a few cents to maybe a few dollars worth of parts, might take all of an hour to fix it. After fixing it, I would buy an

Yes, the NANOVNA offerings are nothing short of a game changer and a wonderful educational tool. Once the (good) universities get word of them, they should be buying them by the hundreds for their RF

THANK YOU!!! Exactly what I needed, perfect! I definitely think I was making them a bit wrong, certainly not precise enough. I was making my center pin on the males too long among other things... I

Hello Clyde, could you tell me what firmware are you using? I would like to update my nanoVNA and use a newer NANO-SAVER. Have you a nanoVNA-H using 2.8" display, or something else? Best 73 Piero

G'day, Apologies if this has been covered - however I have not been able to find anything in my search. I am wondering if others have come across an issue with errors in the lower frequencies of their

From another grumpy old fart (74 yo): Chris, I fully understand your criticisms of 'making fun of the newbies'. It's not really making fun, but our frustration with having no clue how the black box
