I am going to close this as some of this advice is just going to confuse the newer scanner users. The DEC we show in the Database is the Uniden Decimal Value. This is the value that all trunk tracking scanners use. No trunk tracking scanner uses anything else.
To the old hands:
It would depend on what system as to if the HEX value we show in the DB could be converted to the Uniden Decimal value directly or not. The HEX value is not stored in the Database, it is merely displayed; if it was up to me we wouldn't do it as we get more confused questions and even more confusing answers to why it is there. In regard to tower numbers; there is no intention of ever displaying a site number with the HEX tower number.
This thread made me add to the RR FAQ pages on the Wiki. I suggest everyone look there for the correct information.
