I have three power searches with search phrases like:

channel.callsign = "NL1"

(was: channel.callsign LIKE "NL1")

Looks interesting!

This would fail only for programs longer than 6 hours? (no scheduling
until program is over?)
But that would be rare, right?
(if scheduling treats channels separately; if they're all `treated` at
every opportunity other channels could trigger a fresh scheduling if
they have shorter programs at the same time)
