 Does anybody have a formula to find the RF resistance of the secondary coil's
 wire.  I want to make some detailed calculations on my coil's Q, but I need a
 way to find the wire's resistance at 300 kHz.  Wouldn't this be dependent
upon
 the frequency and dimensions of the wire?

Matt,

The resistance of the secondary would be the measured or calculated DC
resistance.  RF implies by its nature AC.  The AC resistance would be the
reactance which is equal to 2*pi*f*L.
