Some unusual SDR application outside EME and commercial transceiver bullshit from vendors.
Digital communications using SDR are cool. We can experiment.

Here are my own thoughts on the subject: -there is nothing to be negative about, else things will never change. we have time. -any widespread adoption will only happen when things are working, or starting to work. So let's play together, we are aware of what need to be done, then document, communicate and publish. Mythbusters' Adam savage always says: "remember kids, the only difference between screwing around and science is writing it down". For the moment Bruce's powerpoints include "DSTAR sucks" and "FreeDV exists". Lets do whatever is required to make him add "some people have a working open source DV infrastructure that sort of works with ONLY open source components, and we need you to test and develop the stuff." -during your own developments, avoid reinventing the wheel. Focus on existing open standards when one exists. For example, use IP, TCP, and things like that. We have a full class-A 44/8 IP network reserved for our own ham use. That's 16 million addresses. If we starve, we will find a solution later. If some people tell you that IP addresses need to be coordinated, then okay, later. Let me play before we need to coordinate. Only invent something when current open standards dont exist or cannot be used. Open standards are good for many reasons: to save time, to ensure interoperability, etc. -In short, let's hack. We are the early adopters, we are designers, but let's try to design with a wide mindset, not just for our own use. Or at least, let's design things with a publication in mind. Documentation means that it will be easier for people to join later. We have the ability to build the future of DSTAR, designed from the ground to match future HAM usages. Forget AFSK. Forget audio bandwidth. Bring the hackRF, bring all the modern tools. Some infrastructure will emerge from hacking. That's nothing new, I'm not inventing anything here, that's just common hacker sense. let's just have fun. Travis Goodspeed, KK4VCZ, publishes a hacking journal with this title : PoC or GTFO! That's a good spirit I think :) Sebastien > > Regards, > Adrian > > ------------------------------------------------------------------------------ > Check out the vibrant tech community on one of the world's most > engaging tech sites, Slashdot.org! http://sdm.link/slashdot > _______________________________________________ > Freetel-codec2 mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/freetel-codec2 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Freetel-codec2 mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freetel-codec2
