when you raise your voice to monopolize a conversation and talk over the other person/people you are with...like a television or radio announcer who broadcasts information because they know their audience can't respond, someone in broadcast mode just talks "at" you or over you, with no regard for your thoughts or response.
We were at a networking event and one of the attendees was in broadcast mode all night. She was so rude never let anyone get in a word edgewise.
