Hello Coilers,

During a period of insomnia overnight I was musing about the need for
tight compling, or high K value, in the driver portion of a magnifier
type T.C.  Has anyone ever tried a bifilar winding arrangement for a
means of achieving this?  My thought was to pull a heavily insulated
lead through a length of 3/8" copper tubing before winding a solenoid
type primary.  You would need to either employ an off-axis inductor
or a variable tank cap to tune, but it sure would yield a high K for
the driver portion.  Ideas?  Comments?
