From: roncraig1@... [] It is possible to tweak the synthesizer frequency setting to account for any TCXO tolerance. I don't think this function is written into the firmware and if it is not it

PS. also not sure how accurate you can be with zero beating. There may be a demodulator low freq rolloff issue..

Hi Herb and Rune The S21 phase delay has been fixed OK and the S21 group delay are still correct, thank you indeed to Rune Kind regards Kurt -----Oprindelig meddelelse----- Fra:

The nano's have a TCXO module which is not adjustable. The schematic shows a DAC freq trim control line from the uP but I believe all the nano's, beyond perhaps the first ones made, have a TCXO that

Thank you so much for the development of the NANO-Saver software. It has been a blessing in my antenna system work. I do have one request. I actually like the metric system but many of those that I

Rune, I'm using firmware 0.4.3Q and the new screen capture module has worked great with all screens I have thrown at it. Thanks for this addition and hope you enjoyed the holidays. - Herb

Interesting. I do not recall having to sudo the previous version. I'm not a programmer, but I'm wondering what changed? The instructions in README.md are the same. 73 -Jim NU0C "Andrew Harmon"

I rather like that "stupid switch". All three actions in one place. Handy. 73 -Jim NU0C "hwalker" <herbwalker2476@...> wrote:

My answer above means, as you probably know, that you can fine tune the frequency of a crystal by changing capacitors around it.

Jim KC2DHU - Let us know if you got it working. Curious to know what the results are. Thanks -- Andrew Harmon - KD5RKO

Oh yeah, forgot the sudo step. I knew there was something else I had to do to make this work! so: git clone https://github.com/mihtjel/nanovna-saver cd nanovna-saver sudo python3.7 -m pip install . --

Hugen, I noticed on the new NanoVNA-H4.2 PCB there is an unpopulated silk-screened area labeled "CARD1". Does that imply that a SanDisk card is in the works for a future version of the NanoVNA-H4?

Multi-function switches still exist. In nanovna-H4, the plastic case can fully protect the multi-function switches, so it is no longer a problem. Unfortunately, our software is still not optimal, and
