The Spaghetti Bowl (D-STAR Political Football) by Ottawa D-STAR Symposium Rick Bandla (VE3CVG) November 27, 2010 Gateway Designs Icom – USTrust – The Original KI4KLF/VA3UW – NATrust ( aka FreeStar) G4ULF – NI Star ircDDB Gateway – Trustless Others? 2 Repeater Controller Designs Icom RP2C controller, software by Icom Satoshi Yasuda (7M3TJZ) board – the first nonIcom, firmware by Satoshi, app by Mark McGregor KB9KHM Mark Phillips (G7LTT/NI2O) board, does not supply firmware, app by KB9KHM Dutch board and firmware by Fred van Kempen PA4YBR, app by KB9KHM Scott (KI4KLF)/Ramesh (VA3UW) linux and dextra-based software-controller (and GMSK interface) + simple PTT circuit 3 Central Databases 1 Needed primarily to enable Call Sign Routing to a specific station US Trust is the first – 1 database for the world – Sometimes slow to update – No cleanup so becomes corrupted – Poorly documented, closed, closely-guarded secrets – Fragile – Also has dplus server database to keep track of Multi Trust was the second – distributed data amongst several strategic servers – Much faster than US Trust – European servers removed when ircDDB came along – North American Trust remains as a scaled down version – dextra based – Now uses ircDDB 4 Central Databases 2 ircDDB – central redundant database – data is rcvd by gateway using IRCclient in Java using RFC2812 – data is sent by gateway using dsm – no interference w USTrust database or dplus database – open source – fast Dutch – dpns or d-Plus name server by Fred van Kempen PA4YBR – Alternative to the dplus database (which only shows Icom systems) – permits hot spots, dvdongles, dvaps to “see” registered hot spots as well as Icom and non-Icom gateways – Does not interfere with other databases 5 Repeater Radio Designs Icom RP2000 (144MHz) Icom RP4000 (440MHz) Icom RP2V (1.3GHz Voice) Icom RP2D (1.3GHz Data) Friendcom Digital Radios Modified FM Radios 6 Network Designs Icom US Trust System – Single trust (central database) – Can use ircDDB – By JRL and Icom HQ – Refined by several US amateurs NA Trust System – Also known as FreeStar aka multi-trust – Multi-trust means multiple redundant DBs – uses ircDDB Trustless System – Uses ircDDB gateway Others – private 7 The Problem We would like it all to work together nicely We would like any mess to be transparent to the user We want it to be easy to use …. well, easier than it is now We want it to be reliable 8 Our Mission Today To meet each other To talk about the various combinations and their respective problems To help us all use the networks effectively To enjoy our hobby 9 The End 10
