Part of his message "I believe this season with 97.9 The Rock has come to an end" says it all.
Having worked a Christian station in the past, I found many people believing God spoke to them about doing something only to change up the game plan. It might be the responsibility of a station, the costs and the babysitting it requires that caused him to rethink his situation, especially given his health issues. Based on the many time the same words were told to me by clients, in each instance it was a cancellation. Given my track record, the station is history.
