Radu, Please note there is a big difference between upper case C and lower case c as an indication of calibration.? Refer to the User Guide in the Forum files section. I emphasized this in the

Hello, You still need to compile it, but I have attached a nanovna-SAVER release that its compatible with the V2 and H4, with the addition of a small form where one can add "attenuation" threshold to

Update NanoVNA H4 firmware to v0.9.1 beta Work around errors in SD card support: Now firmware have beta status and look stable (at this time no errors on read/write on my test card while made 100

I measured the CW frequency error during "my" NanoVNA warm-up. Without the DiSlord's installed FW, the actual error would be shifted higher ! May be not a TCXO but XO as i wrote in a past message.

Looks like it's on its way into Hugen's NanoVNA-H: https://github.com/hugen79/NanoVNA-H/pull/12 Just checked my NanoVNA-H Feb 21 2020 firmware and i don't see that menu yet. Thanks, Chris.

Larry, Thank you for your input. When I run the scan, I see "c1" on the top/left side, and I'm always keeping it current. That said, I just tried in both modes - RECALL 0, and RECALL 1 - and I can't

Thanks Larry, will submit there. Chris.

A much better place for feature requests is in the GitHub repo for the individual developers where it can be commented on and tracked.? On Sat, 23 May 2020 at 9:05 PM, Chris

Was just reading about Reald's "big font overlay" feature from his firmware, looks something like this: [image: image.png] This is great to have as a standard feature in all firmwares. Would also be

Please remember that if even if you've saved your new calibration to c1, if you power cycle the Nano, it automatically recalls c0 and you need to manually recall c1 every time you turn the unit ON On

Just to document this a bit better - I placed my calibration data on "c1," which I'm recalling (and I see on the left side of the screen, on top) before running measurements. I calibrated for a CENTER

Hi all, Having some confidence I've completed calibration on the band of interest to me (I think I did 10MHz to 11MHz), I am getting the same titled scan of pretty much any number of filters I threw

I purchased the H4 from Alibaba. I'm very satisfied. It was $70 USD delivered in less than a month. The vendor was recomended by a microwave group I'm a member of. ?___ Sent from my two way wrist

I am looking for a nanoVNA that will cover 23cms band and has a larger screen that my old eyes can see :-( At the moment, there are several Ebay sellers offering what appears to be the 4" screen

I agree with you. My problem was how to modify this ratio into the NanoVNA firmware; thanks to DiSlord, who modified the code with "my" oscillator value and giving to me the modified dfu file, i was

Hello Dave, The screen shots you appended show just a quarter of thr screen. I think you wanted to append the whole screen size of the nanoVNA. I thought you have already seen that. 73, Rudi DL5FA

Hi Rudi what did you wish to know? My nanoVNA was the 'BAD' clone without screening cans over the input stages and exhibited unwanted vectors due to noise pickup when is Smith Chart mode. Since adding

That's the method HP uses in a lot of their gear. They use a very stable TCXO and to calibrate the frequency you change the divide by ratio. On my 8920 to calibrate the frequency you input a 10MHz

Why not ? As i want to replace my oscillator in the future, a good idea to reverse to a new value ! Thank you one more time and all the best. Rudi

Good, possibly in future i add command for allow user set this correction.
