I've started this thread to bring together experts and novices.

So question number 1.


During a news-feed the reporter is getting instructions and often hearing an in-studio debate through their earphone. How is that audio channel provided, what is the frequency, is it encrypted, is it possible to eavesdrop.

(That's my question - who knows the answer?

Who has question number 2? please ask it here even if nobody knows the full answer to question 1.
