Ken,

a resistance in the range of some kilo-Ohm and some ten's kilo-Ohm in para=
llel with a capacitance in the range of some 100 pF to some nF.
Large variations depending on the brand.

73, Rik  ON7YD - OR7T

Hello all.
Does anyone know the approximate impedance of the mic input jack on a pc=
 sound card.

73.
