Hi Hugen, I recently purchased my from ALI Express. I am totally new to the VNA. How can one identify if it is a clone or not. Regards Oscar

You can contact Maggie to modify, Maggie will choose the appropriate courier, most European countries do not need to add additional postage. hugen

Greetings, I am unable to complete the checkout process with two different credit cards. Do you take Paypal? Dave W6TE

Dear Hugen, that's good news. I would recommend the store to my friends. We appreciate your work. I see that shipping is 15$ for my country (Romania), also for some EU countries, but for other EU

I have made these changes, but I always get an error interrupt. It may be caused by some register values not being reset properly. hugen

The firmware for NanoVNA-H needs to be recompiled before it can be used. You need to modify the MCU and LCD drivers and some UI changes. You can view the code of AA6KL. AA6KL has completed most of the

There are more than 5 clones of NanoVNA-H at present, some are with shielding cases. But due to their wrong assembling, the performance decreases. Assembling the shielding case is to isolate

ann : we just finished the experimental comparison - the results verified our predictions for two constructed two-ports - #83 : On the Doubtfulness - 13 December 2019 -

One last, many of the HP loads are air, the most often home made open and short are PTFE loaded, there is a VF difference. The HP load is definately air (minimal dielectric) to the resistance. The

Have you read the Wiki files for upgrading ? Zadig is not nessecary. And you need to place the boot switch of jumpers needed to start in DFU mode.

Hi Jef One more comment. The load being 50 ohm it is not sensitive to a small displacement of the calibration plane. You will soon see a perfect T-Check Kind regards Kurt -----Oprindelig

Hi Jeff It is not a mystery why it work ? You open offset delay is not 14.491ps but 17.15ps with the C0 and C1 included Then the difference between the short and open is 17.15-16.695=0.45ps so the

Dear Gary, Well, allow us, please, to underline what we already said in: #83 : On the Doubtfulness - 13 December 2019: /g/nanovna-users/message/8173 that is : it is just a "new" -but

I received a nanoVNA last week and tried to upgrade it. I ran Zadig and updated the drive according to Zadig's default suggestion. Once done, I sort circuited the boot0 and Vcc terminals, connected

Thank you again GIN&PEZ; This is both an interesting and exciting journey of discovery and understanding for me. Your diligence and persistence, along with the availability and convenience of modern

Fair enough. I'm a bit sceptical of the T-check method. R&S don't sell the device to do this any any more, but they used to. They only sell verification kits based on airlines and attenuators. Ken

I guess a revisit to using an impedance matching network to solve this issue is required. Once a upon a time we spent significant effort building RX bridges, noise bridges, etc... and spent much time

========================================================== The newest hardware release is the NanoVNA-h, see attachments. It is priced slightly higher than the old release but is a better overall

Mechanical construction of standard have a relationship to the plane of calibration. Basically you can measure that as distance or time they use time as its easy to measure. What does it mean is that
