A while back I posted impedance vs frequency vs # of turns data for the Amidon FT-240-77 toroid (Fair-Rite Products P/N 5977003801). I have updated my website to include plots of the real (R) and imaginary (jX) components of the impedance: http://FT-240-77.notlong.com Looks like the impedance of this material becomes almost purely resistive above 1.4 MHz. Happy Holidays! Mike, W4EF...................... _______________________________________________ Topband mailing list Topband@contesting.com http://lists.contesting.com/mailman/listinfo/topband |
