In the case of radio just ask them to aircheck a couple of hours during a.m. and p.m. drive. Have the student or university overnight it to you and you pay the postage. If at all possible get to the city or town of your potential new employer the night before your interview. You may want to refer to those notes in the interview the next day. If you can't get to the city early or you are driving do not give up.
Radio is easy.
Listen on the way in and take notes. It is a little harder if you are driving in from out of state and it is for a television interview and you could not leave the night before. Try to get to the city of your future employer before noon. They usually have a wall full of televisions. Switch one of the televisions to the station you are trying to get a job at and the one immediately next to it to the station's major competition.
