If you have an XTS3000 with a flash code that includes Smart zone or Smart net trunking, and multi key operation, as well as IMBE, Astro , but only plan on using it for conventional channels, do you need a system key to modify conventional personalities? I don't need nor want to modify any trunking personalities, but if there are any programmed in the radio does this essentially lock out the conventional portion or is it still accessible and editable? Every radio in the Family I have ever programmed has been "Astro ready/conventional analog only" so any information on this would be great, thanks.
