I have a considerable investment into Fusion. I will support this effort in any way I can. I ordered one of the dongles that does Fusion, Dstar and DMR. I saw the YouTube video of the demonstration about this dongle in the Fusion mode. I see alot of potential here in this group Ron N6GKJ On Oct 29, 2015 6:47 AM, "Steve N4IRS" <szingman@msgstor.com> wrote:
When we did the DMR to AllStar testing, we used the NW Digital Radio DV3000. It was mounted on a RPi2 running asterisk. The DV3000 uses AMBE-3000 vocoder chip from DVSI. We tested with Mototrbo and D-Star. Did not have a Fusion or P25 radios.

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

Mike,
You are correct in the statement that the DV4mini needs additional
hardware to handle the transcoding from a digital radio. Once I get my nodes back up on my Raspberry Pi, I will work on an updated version of the D-STAR channel driver that supports DMR and Fusion AMBE encoding and decoding as well as radio control functionality for the DV4mini.

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

I have been waiting a bit before I start playing with DIAL on a RPI2.
I still have two questions 1. Does the RPI2 DIAL version solve the tx echo buffer issue that
the
current version of Asterisk RPI2 code has. The fix to this issue
seems to
be taking a long time. 2. Some users have reorted that a lot of modules have been disabled,
such
as the Echolink channel driver and others. 3. With the new Mini-DV4 dongle $125 and the amount of capability,
has
anybody wrote a channel driver to tie the Yaesu Fusion Wires-X
network into
DIAL. It appears that most of the documentation is out there, we just
need
someone to write the channel driver

Mac, The RPi2 install is pretty much download the image, burn it to SD
card,.
Once the Pi boots, you can login on the HDMI / USB console, or SSH
into
the board on port 222. The board is setup for DHCP so check your DHCP (router) server for
address.
If you want, you can login via the built in serial port at 115,200 System will walk you through setup.

Is there a procedure for loading the "new" DIAL version of asterisk
for
Raspberry pi2?
I am looking to connect either a Pi2 or an intel NUC to a Yaesu Dr-1x using the Arcom RC-210 and the Arcom ADR. I noticed DIAL has
replaced
ACID as the latest flavor of asterisk for both PC and PI2. I have
not
found any install write-ups or YouTubes showing a DIAL install.
Regardless of which platform I will need to use an USB to Serial
adapter
to connect the ALLSTAR node to the repeater controller. It will be
of
the FTDI chipset either a trendnet Tu-s9 or a GearMo USB RS-232.
