I notice when I enter a Canadian Center such as CZUL in the Airport/ARTCC search box the search comes back as not covered by LiveAtc. However in the Canadian listings it has CZUL (Montreal Center) listed with frequencies. And I can pull this up also by
doing a frequency search.
So does the Airport/ARTCC search box only search US Centers or do I have to enter something in addition to CZUL to get
the Canadian Centers?
Thanks.
