STARnet Digital is a new application for use with D-STAR (Digital Smart Technology for Amateur Radio) that builds upon Smart Technology for Amateur Radio, creating dynamic networks of D-STAR radio stations through the worldwide network of D-STAR gateways and repeaters. The fundamental building block of a STARnet Digital network is the Group. Each Group is accessed by a Group Callsign. User radios subscribe to a Group by putting the Group Callsign in the destination (UR) address of the D-STAR radio header and keying their transmitter. Once subscribed, any transmissions directed to the Group will be automatically relayed to the repeater where the subscribing station was last heard. The subscribing station can move from repeater to repeater and upon a transmission from the subscribing station to the repeater, the Group will automatically redirect Group transmissions to the subscribing station’s new repeater. We have a YouTube channel now. STARnet Digital "... no matter where you go, there you are." -- Confucius
