Well, unless the site has several control channels and alternates between them. I've noticed that USAF does this quite a bit.
Sure - but that really wasn't the question. The system won't work unless there is a control channel present (or one frequency or another) at all times.

But if we want to get into more detail - I believe the radios will still work if the control channel goes away but at that point radios default selected talkgroups to fixed frequencies - but at that point it's no longer a trunked system.

What you smokin? Of course that was the question. You just repeated what I said above. The control channel transmits 100% of the time unless it falls back to a backup control channel.

You can argue that there is no such thing has a backup control channel but that's just semantics.

I just got a new scanner and noticed the signal bars are on all the time and didn't know it was from interference or the control channel. Thanks.
