Re: NanoVNA-H version 0.4.0-3 compiled on November 25, 2019
During the "Chasing ghosts" series it was discovered that 8mA creates non-linearities. Can someone that has installed 0.4.0-3 do a S11 measurement of a 25 ohm resistor from 1 to 900MHz? -- NanoVNA

Hi Herb - 4 calibration SAVE areas instead of 5. On the other hand, Hugen maintains code inline that is neither in edy555 nor QRP firmware, so presumably more responsive. Other space was cleared in

Re: Simple way to produce calibration standards #calibration
Your standards could be significantly improved as follows: Short: Don't use wires, too much added inductance. instead use braid or a thin piece of sheet copper (with hole) pushed down flush against

Re: NanoVNASaver -- save points?
Hey dr op 5QR5. Okay. That explains a lot :). But: I think a "X" for load last .cal file would be okay. A textbox can show the filename of last .cal file. What do you think?

Re: NanoVNASaver -- save points?
Hello DE8MSH, Thank you for your comments and your suggestions! Currently, NanoVNA-Saver has no interaction with the calibration on the NanoVNA itself. The application assumes that you have a

Re: Simple way to produce calibration standards #calibration
Only non-inductive resistors are needed around the GHz, which must be soldered to the connector and cut off excess feet. The calibration on the images is appropriate for the shortwave. Calibrations

Re: NanoVNASaver -- save points?
The nanoVNA-Saver does not automatically load previously saved data, but you can create a lot of calibration data yourself and download it as a calibration data before use. You can comment on the
