The Ripper first has to learn a radio station. Tune in to a station and it will start recording songs after around 24 h. To record songs, the Ripper has to be in Time or Radio mode.
It depends on how many songs that are played on the radio station, usually between 15 and 30 per day. Remember that the songs will only be recorded once.
The Ripper remembers a station for 2-3 days. After 3 days of listening to new radio station(s) it will have forgotten all of the previous station but learnt the new station without you touching any button.
Unfortunately not over the radio, as the FM broadcast does not contain that information. The songs are given date, track number and the radio station it’s recorded from.
