why TC Different from others?

To all

I am an average guy that got into coiling. I'm fairly intelligent and a 
quick learner so coiling wasn't all that hard to pick up once I started. I 
was never educated in electronics. So please forgive this question.

A TC primary and secondary form a transformer. The TC transformer produces 
RF when it operates. 1. Why don't other transformers with similar winding 
ratios produce RF?

The TC transformer is part of a "Tank" circuit. The Capacitor the primary 
and secondary "Ring" or oscillate when the capacitor discharges. As I 
understand it, the Pri, Sec and Cap oscillate at (RF) very high frequency. 
2. Why doesn't a NST or other transformer Ring at RF when it is part of a 
tank circuit?   Or perhaps it does. 3. Why do we get 60hz when it rings at 
higher frequency?

Basically I want to know why a TC seems to work differently than other 
transformers.

Thanks for your thoughts
