I've made several 49:1 and 64:1 ununs with these ferrites. They work as expected and are a quality product with no rough edges or abrasions.

Great toroid core with the proper quantum flux transfer ratio well within the bounds of permeability and functional field current control that I imagined in my mad-RF-scientist lab notes.

The FT240-43 ferrite toroid core is a great toroid for amateur radio and audio projects! I use this core with a 10 ft. USB A to.USB B Trip-Lite cable between my Dell desktop computer and my YAESU FTDX-101MP Transceiver to eliminate audio noise from the switching PS in the computer. There are several videos on YouTube that illustrate this use.

These are good toroid cores. Made a couple of chokes with these and they are working extremely well for me. I will be purchasing more.
