It is good news, although I still think MELP was more legal than people think. Andy K3UK On Thu, Aug 26, 2010 at 11:28 PM, J.

Yes and not to forget all the hams put in before the project went comercial and turned into D star and where then simply cut out , ok Georges packet engine went comercial , but he left a good working copy for down load , like the 'new' pic based projects with a $20 pre coded pic , same as a ready made pcb , not quite, you cannot hack out a pic with a broken hack-saw blade ..

Dave says that his new CODEC2 needs work, but the speech quality of the Alpha release is pretty good. He has a few audio samples of CODEC2 and the proprietary codec MELP (for comparison) on his website: http://www.rowetel.com/blog/?page_id=452 For more information, visit Dave's main site at http://www.rowetel.com/blog/ Tony -K2MO

[digitalradio] Signal Around 14113.5 - What Is It?
Hello, Anybody have any idea what the mode/signal is around 14113.5? It is wide on the waterfall and there is no RSID. Sounds familiar but I cannot decode it. Any ideas? Rick - KH2DF
