| May 30, 2022 at 21:35 | comment | added | KJ7LNW | @ThePhoton, you are correct: the s-params I posted were for 3x serial 120nH inductors. Oops! I am writing a command line tool to do s2p transforms and didn't realize the serial test bits were still in place. I've corrected them on the question. | |

corrected s-values
