Details
This conventional circuit has been adjusted to use available capacitor and a trimmer. The inductor resonates with the parallel combination of the cap and trimmer, so I selected a value that resonates within the trimmer range. 26 turns was wound and measured using ELSIE, very close to the 27 turns predicted by the W8DIZ toroid calculator. Note the winding with fewer turns goes on each end - I am not sure how to select different length coils with this schematic program.
