Updating talk groups and alias tables is different with the latest versions. These values are now stored in a SQL database. On both of these tabs, you will see a checkbox for "enable table updates". This option allows the rows in the tables being displayed to be updated from the database. This normally occurs on a frequency change. If you want to edit the table while monitoring, then you can ensure that the table won't be refreshed while editing by turning off the "enable table updates". After making your edits, you can send the changes to the database by pressing the <Update Selected> for the talk group tables (you need to select which rows you want to update). For the alias table, you can press <Update DB>. This will update from the entire table. If you use the <Edit Alias> button, the update to the dbase is immediate and you don't need to do anything but enter the alias and hit enter/press ok.Using 6-13 1909, my edits to the Alphatag value do not stick; they change back to the value imported from the csv file.
Edit: If I uncheck "Enable Table Updates" the changes seem to stick.
