Others here agree with Michael. That includes myself, others who have posted on this forum as well as personal feedback that I have personally received. The ridiculous self aggrandizement takes the

Folks, I have just uploaded an updated Console Command document to the Files section. It now references Erik's last build 0.1.1 with TDR and battery. However, there are a few items that I am not sure

What do you connect on the the third port of the T? Most people connect 50 ohm loads, but personally I am skeptical of the logic of that, as it means both ports see a constant 25 ohms. BNC calibration

Could someone repeat my tests? I have described the issue here: https://github.com/ttrftech/NanoVNA/issues/45 Carlos

XENOMORPH, who I believe first introduced the 1500 MHz, tdr, and battery icon firmware mod, has just released a firmware mod that adds additional 256 point FFT capabilities versus the current 128

Yeah, I thought that would do it as well, BUT it gives reflection coefficient. Alan

Hi Steve, Others have asked for this as well. And I think as far as I know, the short answer is NO. Unless there is a plan to update the firmware to do that calculation and provide a touch key to

Did you try polar output?

I will apologize if this has already been covered. I didn't find it in a search. I see that, by default, NanoVNA reports R + L/C . Is there a way to change that to R +- X ? Yes, I know the PC software

I have seen a technique where the font is "enlarged" simply by outputting each scan of the character font twice. This makes the character appear taller. It can make the text surprisingly more legible

There are two flash parts, one 96k and one 32k Assuming the 32k flash holds the data store (did not analyze yet), the 96kByte flash has maybe 1kByte left. (code + initialized data is in total 97440

Using a not too good BNC Tee I performed a T-Check Attached the measurement (.s2p) and the excel file (.xlsx) in which the T-Check is calculated. Next to the T-Check calculation the excel also

Erik, Thanks for confirming memory capacity is a factor in the font sizes. My progressive bifocals work fine with the smaller fonts, but I imagine it's just a matter of time before someone releases a

Thanks Alan! See, I didn't even figure out it was an S21 measurement :D -- Rune / 5Q5R

Hi Rune, The group delay (GD) is obtained from the transmission phase, S21. The negated value of phase shift calculated as the small change in phase shift occurring with a small change in frequency.
