The minimum possible *loaded* Q that is required to transform between

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.
