You would have to call in when the show is being produced between 6 PM to 8 PM Monday to Friday. From experience we have found that the easiest way to get through to ask a question is to start dialing their number (888-318-7884) one or two minutes before 6 PM. They may not answer until 6 PM but you should not get a busy signal and will have the shortest wait to have your question answered. Usually on Tuesday and Thursday the show is open forum and you can ask any question. Then, when WBPL-LP broadcasts the show the same day the following week, you can get your 15 seconds of fame and hear your question on the air. Your question will also be in the Catholic Answers archive of all their past shows that you can listen to at any time by going to their web site at www.catholic.com.
