Software Extensions to D-Star
By 3rd Parties
• DPlus linking and REF-type Reflectors (REF014)
– Add-on to existing ICOM Gateway server
– D-Star‘s “Killer App“ – Linking is easier and natural
• ircDDB – faster Callsign Routing (add-on)
• G4KLX ircDDBGateway (replaces ICOM gateway)
– DPlus, DExtra, DCS Linking support
– CCS - MUCH Improved Callsign Routing
– Split Repeater
• Multiple Receivers with digital Voting (lowest BER)
• Multiple Transmitters, one system

Further Extensions to D-Star
• DV Modems allow connection of PC to analog
radio to produce D-Star Compatible RF
– Can create Hotspots and DIY Repeaters
– Several kinds (GMSK Modem, DSP Modem,...)
• DVAP (similar to DV Modem Hotspot)
• DV Dongle (use PC‘s speaker/mike)
• Internet connection needed
• Software on PC (Win, Linux, Android)
– Connects to Reflectors/Repeaters/Hotspots

What I like about D-Star
• Clean audio, no static
• You can see callsigns and short messages
• You can easily link to other repeaters and
reflectors around the world
• Let the system find another ham (callsign)
• Can send small data files (larger on 1.2 Ghz)
• Bandwidth as low as 6.25 KHz
– FCC forcing all other services to narrow b/w
– Digital Voice with compression will grow

Example of DIY D-Star • Hotspot extends D-Star to QTH • You control linking to other reflectors • Relatively inexpensive, uses analog radio

SOC Computers Tiny, Inexpensive
• Raspberry Pi (costs $35, total $55 with extras)
– Rpi Foundation – target is computer education
• BeagleBone Black (original was $45, new $55)
• Chinese “Banana Pi“ even faster ($55-$70)
– Don‘t need faster speed for Hotspots/Repeaters
– Faster PCs useful for developers to compile...
• Full Linux PC, can log on from another PC
• Easy to set up using SD image files
• Add an LCD plate with buttons for full control
