If you use the Channel ID's then they are wrong. To get a working LCN for your Uniden scanner take each of those numbers minus one (-1), then divide by 2.
Let's use Fort Erie for example.
420.4625 LCN is 918. 1837-1= 1836/2= 918
420.7750 LCN is 943. 1887-1= 1886/2= 943
You should notice a difference after making this change.
We have been instructed to put Channel ID's in the database. If we put the LCN's in the database we would show a bias towards Uniden.
The database is meant to be a reference for all manufacturers of receivers.
