Edacs trunking system added and/or changed channels..

[AHawco]

I'm using a radio shack pro 164 triple trunking scanner to monitor multiple EDACS system in my area. Lately I've noticed that there is another control channel that has appeared but radio reference does not have any information about it. As well 1of the 2 edacs sites that I'm monitoring is no longer working. I need to find out the LCN of the hole system. I'm only new to the scanner hobby but I would like to be able to figure out the new or changed channels.. I'm in St. John's, Newfoundland, Canada on the Avalon Peninsula. If I buy a newer scanner will it figure out the LCN and the channels of the EDACS system on its own? I have so many questions.. Lol
