Firenet repeaters use about 11 frequency pairs with 3 different tone sets. There are a handful of one-off odd repeaters that don't follow that format, but most of them are set up that way.
The numbers are reused too. Just because 202 is in one place doesn't mean it couldn't be used in another location entirely as well. 202 will, however, be the same freq pair & tone no matter where it is in use.
IIRC the database should be correct, as somebody had a forestry manual a couple of years ago. The channels are all in their respective county pages, not on the main Alberta page.
What conflicting numbers do you have? I monitor and use the ones in the Bow/Crow and Elbow/Sheep areas pretty regularly.
