Re: [DSTAR_DIGITAL] State of the DSTAR Union
Steve, A spread spectrum, frequency hopped version would be nice. It would allow multiple users to use a repeater at the same time. I am sure that would expense the average ham out of DStar until SDRs become common place. 73 David, AC7DS --- On Wed, 1/6/10, bosshardss bossh...@gmail.com wrote: From: bosshardss bossh...@gmail.com Subject: [DSTAR_DIGITAL] State of the DSTAR Union To: dstar_digital@yahoogroups.com Date: Wednesday, January 6, 2010, 9:13 AM I wonder if we just look at DSTAR without Icom's Gateway system or Robin's DPLUS additive, what we would really have. 1 - Very Narrow Bandwidth in terms of spectrum use. 2 - All Digital - not FM with all the variations in quality or lack thereof. 3 - Simultaneous slow text with voice - including built in position reporting overhead. 4 - Advanced features - Individual calling, Group Calling, Call Sign capture, Breakthrough and Emergency Calling (not sure if these are part of the JARL spec). 5 - Reasonably decent performance for AMATEUR radio with product readily available to hams (not hacked or converted commercial radio products).

A streamlined or more intuitive user interface is essential and with new features and flash upgrades the present network will have to change with the times as well. In terms of an amateur grade product, the DSTAR radios are OK. Not great but not all that bad. (Not comparing ham radio to commercial stuff costing 5X more $). Instead of doctoring the present system I believe an eye to the future will be the better course. A Next Generation DSTAR System. Time will tell.

I believe these items are Icom enhancements (The UR callsign is designed into the spec, but I think the callsign squelch is Icom's enhancement). Instead of doctoring the present system I believe an eye to the future will be the better course. A Next Generation DSTAR System. Some of us are looking at this in the background. The air protocol is fine, though the semantics might be improved and it should have included a repeating address. The radio UI is up to the manufacturers, but we can make major improvements to the gateway network. John D.
