Procedure for loading DIAL on a R-Pi2 or a PC

This topic I find very interesting and would like to be included in any further developments. I want to implement DMR on the allstar network. I have access to the DMR-MARC network but it’s pretty closed.

I want my network to be open and people can all talk using the mode of their choice.

I thought a PI with a DMR portable would make a nice portable node. Also being able to deploy a DMR repeater is a must too. The goal is getting it to sound as good as possible and be on allstar!

Last comment on this since it is off topic for this group (but I would love to continue it on a side channel).

When we played with this type of thing we used the DV3000 and a custom version of the DSD code. I grabbed audio off of the discriminator of the radio (or from an RTL dongle), piped it into DSD, took the AMBE frames from the decoder and fed them to the DV3000. PCM was then fed to Allstar through the USRP channel driver. This gave me DMR and DStar (P25 P2 was never tested) decode directly into a test system from the RF side. Today, I would use MMDVM rather then DSD as it implements a much better radio interface and digital path.

The MBE (mbelib) code you are thinking about is both patent encumbered at this

point and only decodes AMBE frames. It does not implement the encoder. I

have extensive experience with that code base and the audio quality as

compared to the chipset is not acceptable. It is good for experimentation,

but I would never deploy a solution with it.

Also in typical ham radio fashion they pissed off the original developer by

taking his code and making it closed source.

Bruce Perens K6BP is working on some legal stuff regarding the AMBE patents,

but that’s still a while out. What I’d suggest is to use the TIA standards

document and then base it off that, host it in a foreign country and make a

script that pulls it in at compile time if the user wants it.

Frankly, I’d like to see the same thing for the IRLP channel driver. Pulling

that just cuz Dave got his panties in a bunch is caving to bullies.

There is a channel driver for dstar that uses a dongle, written by KI4LKF.

I’ve messed with it once, it was not ready for prime time IMO, but then again

there is lots of stuff we runs that’s not exactly stable either.

Yes! I ran it that way with an r100 for a few weeks before moving it over to the msf5000. I had no issues running simpleusb and usbradio. I don't have any of the cracks or pops anywhere that you are referring to running usbradio. I do know what you are talking about but I have never experienced that on any of my equipment.

I thought I had replied to everyone and I noticed I only replied to Neil. I have been running the Debian rpi2 image for quite a while. Way back when Steve first created it. I run it in full duplex mode using usbradio on an msf5000 with no issues at all.

I know what you are talking about with the echo issue. That seems to just be a problem on the arch image on the hamvoip site as that is the only place I have heard it. I did try that image long and and having audio delays at almost 10 seconds and time just made it unusable. That was even using simpleusb. No problems running usbradio and dsp on the Debian image.

To make a long story short, the Debian image just works! No have had zero issues with it.

I have been playing with the full duplex mode using DSP decode (PL, carrier squelch) in and out on the RPI2 with DIAL and so far it seems to be on par with what Acid does on a PC.

There is some latency due to audio processing but its about 200 to 250 ms and seems to be stable. I have never seen an acid box with 0 latency on the full duplex audio.

In may opinion it woks just as well as an ACID set up on a pc for a single full duplex repeater node.

Can;t speak to the other questions though.

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.

Why?

This is where allstar has it nailed
being able to link multiple audio paths. We have someone using dstar on our
system it sounds pretty decent. I'd like to see p25 and DMR included. I'll

I would like to see asterisk being the common platform used for internet
linking of any radio systems. It decouples the network from the technology.
Course this does remove the network operators from the god like status they
have and the ensuing circle-jerk :slight_smile:

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

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

  1. 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.
