Band plans in basic terms are trunking tables, that help the scanner trunk track the system properly.

They have become much more used recently with all the rebanded / different trunking tables (UHF VHF) that are being used.


You also have a premium membership, if you cant figure out the bandplans you can use FREESCAN and import directly from RadioReference database and (that will input the bandplans).
