Zion for all the Nations
Tune in: High or Low
Avoid using radio jargon on the air such as "PSA," "promo," "cue," "cart," "pot," "log," and so forth. Anything that requires the context of having gone through DJ training at KPSU puts the listeners off because they don't know what you're talking about. Use the gearhead rule of thumb: if you need to give more than two sentences of backstory to make an anecdote or reference comprehensible, let alone funny, then you probably should talk about something else. The word "break" is more than satisfactory when discussing stepping away from your normal show content in order to play PSAs or Promos.
