As I stated in this thread:
http://forums.radioreference.com/eastern-canada-radio-discussion-forum/159379-region-waterloo.html , LCN's 12,13,14, and 16 are NOT currently linked to the control channel that serves up our regions radio transmissions (fire/police/transit/municipal/etc). Those 4 channels have however been linked together with a new control channel as a new system of sorts - which we have yet to obtain any real info for.
If your scanner is getting stuck (or quiet) every now and then (due to being hung up on this other CC), simply lockout those channels so they will not be scanned. The mentioned channels have NO related traffic whatsoever anyways as they are part of a new system.
69stiles - even edacs radios would have this problem if they were configured incorrectly. I'm positive this is something that has not been overlooked...
Edit: Just fired up the scanner to take a look at that second CC(system) again, and as of 11:30pm EST it appears to be gone. Also, the LCN ordering (transmit selection) has been modified, and now includes the channels I previously indicated weren't part of the system. Maybe they were just doing some advanced radio tests afterall? Current CC in use is LCN #9 (or 866.475mhz) - a channel I've not seen used before...
