RE: [DSTAR_DIGITAL] State of the DSTAR Union
I'm not really sure why a change to the air protocol is needed. Sure there could be a lot of changes to it, but I think that most of the changes that folks desire would be either in the network or radio GUI. The network is something that is just going to take a while to occur. The radio GUI is another item and that is really something that is at the discretion of the manufacturer. Kenwood has evidently decided that flash upgradability is a desirable feature while others haven't subscribed to the concept. Often, a lot of the functionality is driven by the elements on the radio's LCD screen and can't be readily enhanced. (The exception being the larger radios with fully bit addressable displays) Now, the other side is that Icom's radios ARE upgradable. I believe that there have been a couple of radios that have had software updates, they just need to be sent back to Icom to be flashed. Do we need a new air protocol? I don't know of any features that would make me want to change it.

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.

Posted this to another list. A smart comedian who helps keep it all in perspective... http://www.youtube.com/watch?v=rOtEQB-9tvk :-) Happy New Year, all... D-STAR is fine... carry on.

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 wrote: From: bosshardss 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).
