I bought my NanoVNA in large part to have a solution looking for a problem to solve. My main use for this device was the SWR sweep capability for my antennas, but I soon discovered previously unknown

Theory is always incomplete. It is said that the field of thermodynamics learned much more from the operations of steam locomotives than steam locomotives learned from thermodynamics. Often electrical

Hello everyone, I am a beginner in using the NanoVNA, I have a calibration problem after connecting a transmission line into the VNA. You can see some pictures of the result in the attached document

Hello Ed, Op vr 15 jul. 2022 om 11:23 schreef Ed G8FAX <ed@...>: Thanks, but when I get a better grip on the OCFD (aka being ableto model and include in that moe the Choke) I plan to

Hi Victor, Oh wow, what a fantastic webpage you have, full of useful information. Your attention to detail, investigations and experiments is exemplary and I congratulate you for all your efforts. I

If the "practice" is not in agreement with the "theory" it is that there is an error (a fault) in one or the other, to see in both. -- F1AMM Fran?ois

Thank you for your prompt reply DiSlord! I much appreciate your extraordinary initiative and hard work to support the NanoVNA.

Thank you all for comments and criticism. I have always been a practical and experimenting man, sometimes, defying theory

Hi Francois, Thank you for your contribution. The image you refer to gives a method for testing aspects of a 4;1 voltage balun, see link in the other ref you provided http://vk6ysf.com/balun_4-1.htm

Hello Ed, I mostly do CM0 measurements on Chokes, but I checked the OC one to see what it did. I think G3TXQ used OC, but not 100% sure (he does not fully describe his setup in:

Need copy from SD card PS in last firmware i add Load from SD card S1P, S2P, BMP, CAL files. https://github.com/DiSlord/NanoVNA-D/releases

Hi, I have finally made a small slit on my NanoVNA H4 and have tried saving a couple of s1p and s2p files on its 2gB SD card. Do both the NanoVNASaver and NanoVNA App allow access 1) from the device

I believe this should be a personal decision and not the consensus of a group of...... Do the research on your own, present your conclusions to a group, and make a decision. Don't reverse the first

After 35 years in IT, I’ve learned a few things about software/firmware upgrades. The decision to update *anything *depends on 3 factors: business need, supportability, and risk. This is true of

Hi Victor, Thank you, I await your results on DM measurement after your parts arrive, if you are kind enough to post them. I hope you have better experience than I on delivery, I ordered some items

Sure, but a PPA simplify update.

I also upgrade.. In some cases just minutes after an upgrade is available (example sdrradio console)... But that's off topic grin I am also a member of test team group.. So if you are not fear of

You will find a lot of useful videos on youtube... If you looked a few of them you at least know some basics What is that damned smith for?? How to calibrate What are all those traces mean How to
