thanks y'all for the suggestions! my toroids have arrived today from Mouser!
time to wrap up lots of my wires! and share them with some local hams
thank you!
these are the FT240-31 I've been looking for 🙂

Do your Toroids need a little extra juice to get the job done? https://youtu.be/Mh9jXCeSong?si=AnXkXTGR0LX5YNOL

I don't know if there's a simpler name for this #polyhedron than "a quasi-convex Stewart #toroid of genus 11 whose convex hull is the truncated icosidodecahedron."
Either way, I love this shape, so I had to make one.
@laren Don't do anything special before you have problems. No point spending time and energy on issue you don't have.
I had issues. Keying the radio killed the USB-connection between laptop and IC-705. I made a hack (see photo), but it works. Maybe I'll clean this some day and downsize the toroid (FT240-43).
Determination of the high-resolution structure of yeast TORC1 allows characterization of the precise interfaces of interaction between inactive TORC1 and TORC1′ polymers and identification of the mode of binding of active EGOC on TORC1.
These recent plasma toroid toys I found on YouTube really piqued my interest. Got my creative juices flowing, now I need a napkin.
