Your numbers don't add up. Impedance increases by the square of the number of turns but only linearly by the number of cores: 14^2 (196) >> 2^2*6 (24) 73, ...

This one has 2 turns but has 6 cores so it may not be far off. 73 John G3UUT _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
