Beg to differ with you, the scanner will scan each tower site separately, it doesn't lock onto the State or County and just stay there on that site forever. If no traffic it moves to the next tower site. All the TGIDs are in the listings, and when locked onto a tower during a transmission, the corresponding tgid list will be used.
On my own system I have 6 counties in the TxWarn system and the scanner rotates its scanning between them and 26 conventional channels. Then I have all the TGID's for TxWarn for the area entered so whatever is needed is used. The 6 TxWARN towers are not programmed as separate systems with serparate TGID lists. No difference in how I programmed the file for him to use.
Only 6 towers active, other two in process of being activated.
