If the Big Top 40 overran on IRN3 it would go to IRN3 tones at 18:59:30 and switch over to Wireless Group at 18:59:45. However, this wouldn't matter on the majority of stations whose playout systems switch the satellite feed on/off on a schedule and fire the next event. It would cut out at whatever time they have the BT40 set to switch off.
