Re: Measure CMC - bit confused


 

Sirs, you have thrown down the gauntlet, Sir, and I accept your challenge. In my previous life, I was a more than adequate spreadsheet wiz. So I should be able to handle this job. haha. First, the object. Build and validate a CMC based on this published and evidently respected source. Specifically the 11 turn on 2.4 #61. I think I know how to wind wire around a core and count to 11. So that is one. Picture attached. Now I want to validate that the CMC delivers (about? sort of?) the same Rs as k9yc published in his NM/THHN #12 on single 2.4 #31 Toroid table.

Using my beloved nano, I built a test jig (please don't laugh too hard...), tried to calibrate over 1-30, and saved the required s2p file. Then imported that file into ZPLOTS from AC6LA. The spreadsheet loads fine, and the initial plots appear fine. But. When I click "generate data" to get the resistance terms, well, it all goes to zeros. So I'm screwing something up here. I've attached the populated spreadsheet and the raw nanosaver output fine.

can anyone give me the slap in the face I need and set me straight...?

Thank you all soooo much.
