Re: First PCB pictures of the V2
Any chance you can add the option of rotating the display graphics 180 deg? I can see the cables coming out of the bottom being a nuisance in some instances. And please get rid of that ridiculous

Re: Some test results using a NanoVNA
You are correct Alan, I was too hasty in my enthusiasm.? And when the result is pure resistance there is resonance.? At frequencies above self resonance an inductor acts as a capacitor. Which

Re: First PCB pictures of the V2
I would also like to add my voice to the many that would want to purchase this with a larger screen. How does the larger screen you may or may note use compare with the 4.3" on the NanoVNA-F? The 4.3"

Re: Some test results using a NanoVNA
However, the result of distributive C for an inductor which is one appropriate model, shunt C, leads to an inductor value which INCREASES as we approach SRF. The arithmetic for this is; Xt=

Re: Quality of shipped cables with NanoVNA-H

Roger, it's really very easy to make your own cables. There are SMA connectors that use the 'solder the center' and 'crimp the shield' type of construction. I use this method on all my connectors,

Re: Some test results using a NanoVNA
One addendum regarding inductance.? I did mention that 50 kHz as a low limit prevents measurement of large inductances. I just measured a few and got good results up to around 50 mH.? My inductance

I have read numerous comments that state that the quality of the cables supplied with the NanoVNA is poor. However Hugen has supplied good calibration terminators in his NanoVNA-H in the gift box

How to measure inductance?? Very simple.? First, you make up an adapter so you can connect the unknown to the nano S0. Calibrate the nano.? The next step depends on the inductance.? Select a

Good job, perhaps offer the option to rotate display 180 degrees so connectors and jog switch point away from user.

I wish you had chosen an alternate location for the selection switch. Right between the connectors will be awkward to use. It probably would have been better to swap the switch and USB connector
