Hello group,
I found this 8mm torque wrench on eBay:
It is factory preset for 0.59N-m which is just below the upper limit for
brass SMA connectors. It seems to do the job and the price is very
reasonable for the quality represented.
Might be worth a look. I have no relationship with the seller.

Re: NanoVNA USB C connector is stuck
Anne, with your great sense of humor this will only be a minor setback.
From someone who can usually find their hammer.
Good luck!

I've re-enabled SD card Igor, though this is the compile without the external 32k xtal enabled - for now.
I've not yet added the dual graph DMR wants, but will get there. I've done a lot of other updates though to the PC test software, all the graph min/max scales are now working and saved/restored - hopefully.

Re: NanoVNA USB C connector is stuck
Thanks for replies.
Luckily I do not have a case , and that is the only reason I need to unplug it so I can build one.
The USB C connector went in with noticeable click.

PS
Not to worry , I cannot find the hammer.

If it did save 6k of flash, I'd be able to add a proper small (minor flash size usage) spline interpolation routine that would be far better than linear interpolation, so I'll look at that then at some point DiSlord.

float s = sin(w);
float c = cos(w); If you remove this use - it allow save ~6-7k flash. sin cos functions use big size tables for calculations, but i think possible use more small float value table for 1/4 round (possible use from fft.h) and made interpolate (yes error exist, but small, error noise more big).

I understand! The limited size is really precious and needs to be used carefully. There are no problems. I appreciate your work.

Thank you.
It's just the usual compile time options near the top of the nanovna.h file that need to be changed according to your desires. This last one I posted here had the SD card disabled and the LC matching enabled. It's because their's not enough flash space in the CPU for everything at the same time, 10k of flash is at the moment laying empty and wasted and unusable, which is very bad really, it needs to be sorted. I've only been doing one firmware which was a branch off dislords at the time I started.

Well, it appears that both DiSlord and OneofEleven are making their own changes and releasing roms separately in this thread.?

Re: NanoVNA USB C connector is stuck
Anne,
unlike with most mobile phones, the NanoVNA-H4 (and presumably H) USB-C connector gives a click when a plug is inserted. It needs a little more force to uncouple than with a typical phone. That said, the USB-C connector is designed to be non-latching, unlike microUSB. Checking here, a straight pull with finger and thumb on the plug should release it. There is not much case clearance, so there is a possibility of the plug fouling the case, but it seems unlikely. More likely that the plug is tight.
With mine, a quality (but not cheap) cable releases more easily than the supplied USB-A¨CUSB-C cable that came in the box.
Whatever you do, leave the hammer in the toolbox, well away from the nanoVNA!
73, HTH, Stay Safe,
Robin, G8DQX

Hi Igor,
Please be more specific - what Nanovna version (H, H4, F) and developer's firmware (DiSlord, OneofElevin, Hugen, etc) are you asking about?
Thanks
