Perfectly true if you don't use a transformer. The link coupled tuend  
circuit is a tuend transformer, and the impedance ratio is determined by the  turns 
ratio. The Q is determined by the ratio of inductive reactance to the load  
impedance.
 
Going away shortlt, so may not be able to read e mail for some weeks.
