" ¡ The latest version has fixed the (offset delay) bug. I just made a number of tests using NanoVNA saver 2.2 with different length cables and got good results by just entering an estimate for one way delay and then varying for best results while watching the Smith Chart and S11 phase delay. .
I also compared using the offset delay in the program and the equivalent electrical delay parameter in the NanoVNA hardware and got agreement there as well. The electrical delay used in the hardware parameter is the round trip delay so I divided by 2 to get the offset delay in the Saver program. "

Roger,
I'm sure Rune will be happy to hear those results. Kurt Poulsen had previously provided feedback to Rune that the "S21 phase delay has been fixed OK and the S21 group delay are still correct."
Kudo's to Rune for his usual excellence.
Crazy Houston and Chiefs game in progress.
