Hi Frank, When an option of ARRL membership was a CD received at the end of the year, then I took that option. This was an economic choice as the CD contained not only QST but NCJ (no interest) and

I am a bit confused on the Marker Menu and the Markers in general. I know I can turn them on and off and move them and read the values on the screen. I know that I can click on one and then the others

Will the reactance of NanoVNA's channels influence the resonant frequencies of the choke, or the calibration process is removing this influence? If the influence is present, what method will minimize

To find a series resonance you are looking for the frequency where the impedance is a minimum. All three techniques you suggest will work. 1. Series between two ports, look for the frequency of

ive downloaded the reald firmware but there is no hex or dfu file??

Hi, Rune! I have read your conversation with Bryan WA5VAH about TDR. As I understood, there is a problem with putting the device in TDR Transform mode and back in NanoVNA Saver. Yesterday I have made

This is where radio clubs are handy. I am really surprised at the hidden technical level of some of my club members. They don’t wear a badge or sign showing their skill level. They might even
