Nope you didn't bust class C. The controller terminated radar
service, but you're still on his frequency were you?
Yes, I am quite sure I was still on freq. but I do not recall him
telling me Freq change approved either.

You should, however stay on his frequency until you're cleared of class C, or to
receive prior permission to change frequency if you're still in class
C.

Good point. I will certainly file this in my memory banks. Thanks for
your time on this.
