ATC says "radar contact, 20 miles south of XYZ, proceed on course". Do
you acknowledge this transmission? Do they want read back for everything,
or should
we shut up as much as possible?

The best thing to do is click your transmitter twice.

Where did you hear that? ATC does that. But there's only one of them on
the freq. Pilots shouldn't. ATC requires a verbal response.
