I am pleased to announce the launch of a Kickstarter for a 6 Channel USB AMBE device <https://www.kickstarter.com/projects/985312845/6-channel-usb-ambe-transcoder-for-digital-voice-sy> which is compatible with the XLX Reflector System. The XLX system creates reflectors for the DCS, DExtra, and DPLUS systems and also supports integration with DMR. To transcode AMBE+ (D-STAR) and AMBE+2 (DMR/YSF/dPMR/NXDN/P25-Phase 2/...) requires a hardware solution. This can be accomplished using pairs of ThumbDVs or other USB based AMBE-3000 devices. Reflector systems may have multiple reflectors (A-Z) that require transcoding simultaneously, which requires multiple streams available and that is where the XCode-3006 comes to the rescue. The folks behind the XLX system designed a board that can provide up to 6 streams on a single USB port and it is in operation now at XLX950 (XRF950/DCS950/...) which is using the board to cross connect with DMR. NW Digital Radio is running a Kickstarter to fund an initial build of 50 of these units. 50 units is the minimum production run in order to keep costs down. This is where you can help: If you run a reflector, you can obtain a XCode-3006 via a pledge on the Kickstarter at one of two levels. If you use a reflector, you can help the operator of that reflector by helping them obtain a XCode-3006 via the kickstarter. If you just like the idea of a six channel AMBE transcoder, and want to help out, there are pledge levels for supporters like you. This can only happen if we meet the funding goal set for the Kickstarter, and we only have 30 days to reach it. Having this board available opens the opportunity for other projects such as: Analog <--> DV Gateways (eg. Allstar, Echolink, ... to your favorite DV system) DV --> Analog Streaming for online monitoring of DV systems ...

I'm wondering, why not fund the development of Free Software that would do this on the host CPU? I've been working with P25 (IMBE) now and have a small project coming along (just got the RS decoder working). We were able to take the open source IMBE codec from the op25 project and get encode and decode of the voice streams working. We're even looking at taking the Yaesu fusion wide format and repacking the IMBE data (all 11 bytes) as a v.24 frame and sending it to a Motorola base station. Now none of this really helps going from IMBE to AMBE, but the same idea could work here between the various over the air formats, no? 73 -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net

Doesn't apply to source code. Perhaps we should fund the research neasary to prove their patients invalid. The main one on IMBE is expired this year, and would follow through to AMBE too. This would really benefit the community. There is much progress in amateur radio stifled do to this. -- Bryan Fields M: +1-727-409-1194
