Guys,<br>
<br>
I haven't looked carefully as to which variants of AMBE are in use by<br>
D-STAR, Fusion, etc...Doesn't the original AMBE patent expire fairly soon?<br>
<br>
The reason I'm asking is that I know there are some fledgling open-source<br>
AMBE implementations out there. A couple years ago I hacked CODEC2 into<br>
Asterisk for experimentation, thinking about directly linking to HF via<br>
the FreeDV project--and, not wanting to transcode from one low-bandwidth<br>
CODEC to another, making truly awful audio!<br>
<br>
After playing with it a few weeks, I didn't do much more...(I've still<br>
got that code and it still works, if anyone wants to play with it?)<br>
<br>
...Just wondering.<br>

Actually the DV4Mini alone does not help tie Allstar into Wires-X. In<br>
order to do that one must:<br>
<br>
1) Have an interface to the YSF network protocol<br>
2) Decode and extract the AMBE frames from the streamed protocol<br>
3) Transcode the frames to PCM at the proper sample rate using the DVSI<br>
AMBE3000 chipset<br>
4) Send those frames to something like the already created USRP channel<br>
driver<br>
<br>
In reverse, 4, 3, 2, 1 to send data back to the YSF network. In<br>
addition<br>
to the simple outline above, you would want to<br>
a) Add audio filtering/shaping to make the AMBE audio more acceptable<br>
to<br>
what we are used to on Allstar (one of the single greatest aspects of<br>
Allstar is the audio quality)<br>
b) Transfer of as much metadata between the networks as possible<br>
<br>
The DV4Mini is a radio module + digital modulator (DStar/DMR/YSF). It<br>
has<br>
no AMBE encode/decode hardware so there is no way to transcode the<br>
audio<br>
content. For that a "ThumbDV" or a DV3000 would be the hardware of<br>
choice. The DV4Mini could be used as a user radio on an existing RF<br>
network, but one would still need the AMBE3K to do the transcode.<br>
