I want to know the answer to the following question:
What is resonated by a capacitor along with the receiver tuning that maintains resonance over the AM broadcast band?
All the background I'm provided with is that "Resonating such an inductor with a capacitor at the frequency of operation not only cancels the reactance but greatly magnifies the very small radiation resistance of such a loop.[citation needed]". Is that enough to answer the question?
Answer: no
