Not sure how this relates to the tower thread, Paul -- but the answer is no. The repeater callsign is used for "access", from everything I've read. Also you MUST have a club callsign for the repeater if the ham that owns it wants to access it. (His user radio would have his callsign, the repeater must have its own.) D-Star has nothing like the P-25 system with a NAC, or "pseudo-NAC" like the ones defined in the specification that act like carrier squelch systems and allow all users with digital signals through the repeater. It also has no talk groups to speak of. A shame, really. It's not a very well thought-out protocol for the typical uses of Amateurs. -- Nate Duehr, WY0X [EMAIL PROTECTED]
