Tom AC2IE has built a GNU radio block for D-STAR using the ThumbDV.

I have built GNU Radio blocks to encode and decode DStar. These blocks use NWDigitalRadio's ThumbDV for the vocoding. My OOT (out-of-tree) module is at https://github.com/ac2ie/gr-ambe3000.

The DStar Decoding block is mostly complete. The decoder prints any incoming header as well as any "slow data" in the voice frames. (Of course the main output of the decode block is the audio stream!) A GNU Radio flow-graph for a DStar receiver is included. (See the picture below.)

Encoding is still a "work-in-progress". Output of my current DStar Encoder block does not have the prepended 660-bit frame header and frame sync. The output is also not properly terminated with a terminating sync flag. In spite of these shortcomings, a flow graph is included that will transmit a valid voice stream that can be successfully received with a DStar receiver, it just won't have a header or a terminating flag. I'm still working on the details of how to implement that in GNU Radio.

I'm hoping to get some information that will hopefully anwser why I've only got my Thumb DV partially working.

    I just got a Thumb DV - with a few hicups and some help from John Hays -- I was able to get it configured to a point where I think it's working.

  However I can't get anyone to respond to me.

 my setup is as follows:

   Windows 7 Pro - PC

   Thumb DV DV3000U

   DV Node for Windows 1.5.8 P3

   Plantronics Headset   

Installed everything, and configured as instructions say ...

I get the VU meter to respond when I transmit and my results show I'm transmitting, but no one responds.

I've submitted my callsign for registration on my closest D-Star repeater W1SCC 

however it still shows that I'm NOT approved and yet it's been a week. I was expecting it to be quicker than that.

I REALLY hoping that my troubles are all routed in me NOT yet completing the registration process, and it's preventing me from my XMIT from working.

  I've tried contacting the the administrator of the repeater, without success. My emails have not bounced but have gone un-answered. I'm kinda stuck because I'm told that you can't register on more than one repeater at a time and don't know how to get anyone to help.

  I guess I'll just have to wait .... I started the registration before I ordered my ICOM ID51A Plus; and my Thumb DV in hopes this would be all behind me.

   Any advice or insight would be appreciated.

 I even see myself in the Reflector's website log ... ( but just as "LISTENING" )

    I can listen to gateways & reflectors -  XMIT - but no response if I was closer to the repeater I would use my HT to try as well, but it 46 miles away. That's why I wanted to go with a Tumb DV or DVAP.

Dplus reflectors block unregistered users. Try xrf Or dcs reflectors.

I know this forum is really for the hardware aspect of the device, or at least I'm assuming it is. But I'm hoping I can get some help trying to understand the operational side of the device and technology as well.

My two questions for this post are as follows.

1,)  when configuring the Call Sign suffix what do each of the letter choices represent? (I'm currently using A) I see many users with A,B,C,D

      I'm guessing that it's A=23cm  , B=70cm  , C=2m ,   D=Dongle. Should I be using 'D' as I'm connecting with a Thumb DV. ?   

2,)  when configuring a DCS gateway, the letter designation seems to select a 'group' that you are labeled with while on the reflector.

       ie. I currently use a gateway of DCS006 N  which labels me as : USA Florida Group(N)

       while listening do I hear ALL group traffic? or only those in my 'N' Group?

I'm hoping someone can help me or point me to a site that shows how to configure a Thumb DV hotspot dongle for DStar ?

   I finally got my callsign approved on W1SCC DStar repeater - I now need to configure the Terminal ID(s)  --

    I followed the video instructions from ICOM to set it up for my radio ID-51a, however I'm not sure what if anything I need to do for my Thumb DV setup running DV Node for Windows.

     All of the terminology is just alphabet soup to me right now. Until I understand abit more how this stuff works I'm kinda lost. 

     I created a second terminal on my account placing a "C" for initial, and adding a PCNAME of callsign-dongle saved it and hoped for the best. I used a "C" for initial because that's what is setup in the DV Node Client software.

     However I still can't get anyone to respond to me on the REF030 C reflector - I can connect and hear everyone fine. I XMIT and my VU moves but no one seems to hear me.

     Just looking for some resources to learn how this software and technology works. If I was closer to my W1SCC reflector I would test my connection with my HT - but that's not possible from where I am.

Just an UPDATE -- I'm up and running ..... disregard my previous post.

  The only thing I changed was the callsign server - I was using Free*Star; because the Dutch*Star kept giving me errors or wouldn't connect when I first configured the DV Node. Im HAPPY to report just switching to to Dutch*Star DPNS -- made everything HAPPY! including me.

New documentation pages have been created in the Wiki

I administer a dstar system, W7VOI. It has worked well for a couple of years and continues to work adequately with a single anomaly.

Thanks To John D. Haysi have nearly got the thumbdv pi 2 working i must have just one thing wrong will put what i have done with John D. Hays 

tomorrow and see if anyone can see were i have gone wrong (I do have it working on win7 ) so must be a config error some were even done the ehco test with -------E and that came back fine

its just this cannot find user G7ICD and the connect to what ever repeater/reflector it says ignoring shows on the log will post more tomorrow as it wa past my bed time

thanks jim

could you please have a look at these snap shots and see were i am going wrong i have puy them on my own site so not to fill up yours
