All too often we receive criticism for something we have accomplished or completed. Well, that is not the intention of this email. My life-long philosophy in such things is that a milligram (choose

HI Ed, Have you tried downloading it from this link: https://gofile.io/?c=NvYLRD Kind regards, neb

Hi betex, Thanks for having interest with the software, I posted the latest version here:

Hi neb, your software looks quite nice, but unfortunately the link has expired... Could you please upload it again? Many thanks! betex

Many thanks for all your answers! Taking now a 2m cable with ferrites at both ends is working really great! No more signal-affecting when connecting to USB!! :-)) ...and of course it might not be a

And check the connectors, not the markings on the cable. I have seen 75 ohm coax jumpers with 50 ohm BNC connectors on the ends. Such cables are not recommended if you are using a resonant antenna,

Hello pgc1682, Thank you very much for your help with SimSmith. Unfortunately I cannot follow your explanation. I have loaded my data file nanoVNA_RG173-30cm_202_500MHz_Open.s1p in SimSmith, see

I would not say the matching is poor on port 2. I measured it using my HP VNA. At least on the NanoVNA sample I have, the return loss on port 2 is better than the specification on my HP 8720D VNA. I

Why not just calibrate for the frequencies you care about and save as your default? It doesn't seem like a custom firmware is needed to only see a segment you want. Since it is less than 300mhz, you

Hi Erik Fantastic ... I did not know you was maintaining TAPR VNA (or I had forgotten it) Looking forward to follow your project. My transfer switch is also Sivers Lab but only PM7551 ? with a

Two questions to answer: 1: Is there anything you can improve for HF by removing/adding it from the current firmware of the nanoVNA? The only thing I can think of is to force the SI5351 to always use
