The only way for the fallback to return to radio is that its first
source (the big switch) becomes unavailable. The fake_src are not a
solution. Without them, the switch can remain available after the time
slots (e.g. after 7:15) if a news_src track keeps playing. If you're
planning to play only one track per time slot, you can use a delay()
to avoid that another track starts before the end of the time slot.

There are several other solutions depending on what exactly you want
and accept. For example a track_insensitive switch will interrupt its
current track at the very end of the time slot. (But the track will
resume with the next time slot unless you skip it...) I encourage you
to play with various configurations on simple examples. For example, I
was running this to check what I said:
  liquidsoap 'out(fallback(track_sensitive=false,[switch(track_sensitive=false,[({11h08m30s},sine(duration=5.))]),sine(220.,duration=10.)]))'

Have fun,
