		    . . . .  This picture shows 7 passes

   of wire through the core for an effective

   inductance 49x that of a single pass.

   Hence, one would need to string 49 single 

   cores onto the coax as a string of beads to

   equal the effectiveness of one core wound with

   seven turns . . . but generally useful only

   at 200mHz and below. 	


    My third grade teacher visited me in a dream

    last night . . . raised her eybrows and said,

    "Are you sure 'bout that?"
