ThumbDV used as an AMBE Server
TG9AOR
Hello Community. So as to check if I understand correctly, it is possible to insert the ThumbDV on a USB port on my Raspberry Pi 3 that has a DVMega installed. System is Compass Linux. So I may install AMBE Server as described in the Wiki, set it up as Repeater 2 on ircDDBGateway (Repeater 1 is the DVMega), and access it from wherever with my dummy repeater program on my personal device. Did I understand correctly? Thanks. Joe TG9AOR

John,

It is a DV3000 pic header. Also thanks for the info on the not O but 0. Makes more sense. I will give it a try. Abbot

Re: AMBEserver setup issues
Do you have a PiDV (plugs onto a Raspberry Pi Header) or ThumbDV (DV3000 could be either)? Note it looks like you are trying to turn on ttySO (letter capital 'O'), the last character is the number 0 as in ttyS0

Hello, I am a newbie to linux and setting up my rasbperry pi 3 and my NWDR DV3000 board. I am using the Compass load and have followed all the steps so far but keep getting this error and not sure what I am doing wrong. I was wondering if I could get some help or at least pointed in the right direction. pi@compass01:/etc/opendv $ sudo systemctl status ambeserver@... ● ambeserver@... - DV3000 Daemon Loaded: loaded (/lib/systemd/system/ambeserver@.service; enabled) Active: inactive (dead) pi@compass01:/etc/opendv $ sudo systemctl start ambeserver@...

Re: DStar Tinkering
Hi Rob, The PiDV and ThumbDV are AMBE encoder/decoder devices and don't have anything to do with RF directly. You can get on the D-STAR network with them using software on your computer and connecting via the Internet. The Wiki is a good start. https://nw-digital-radio.groups.io/g/ambe/wiki/AMBE-Devices Unless you are building a dedicated AMBEserver on a Pi, the ThumbDV is more flexible since it can plug into the USB port on a variety of computers. https://nw-digital-radio.groups.io/g/ambe/wiki/AMBEserver-Addendum John

DStar Tinkering
Rob Ogilvie (K8AXE) <rob@...>
Howdy! I play around on 2m packet a fair bit and am interested in checking out what DStar has to offer. I'm always interested in means of getting MOAR SPEED out of these rigs. Is the PiDV plus my existing RPi2 boards a good option to dig in and start tinkering? There are a few DStar repeaters around me. I have two 2m/70cm FM-only radios and am not sure from the documentation how the PiDV interfaces with them or if it's a transmitter itself? Is there a good starter document out there? 73s!

Re: dsdcc
Steve <kb9mwr@...>
Some things I have noticed; Apparently you need the mbe library even if you use a AMBE dongle... I wasn't able to get around this dependency. On the other side of the coin, apparently you also need to build serialDV even if you don't use it. We were able to get dsdccx to work with the NW digital dongle. But not without, as we get the "Error writing to output" repeatedly if not using the ambe3000 dongle. And lastly I don't know if its just me but RTL devices on the Pi seem temperamental, as I get PLL not locked often. Wonder if its related to no real time clock or something. Here is a basic guide. http://www.qsl.net/kb9mwr/projects/dv/pi-rtl-dsd-experiments.pdf

dsdcc
Steve <kb9mwr@...>
There is a new C++ rewrite of dsd, the digital speech decoder, that can decode P25, DMR, D-Star etc. It's called dsdcc ( https://github.com/f4exb/dsdcc ) It also supports doing the decoding with a AMBE hardware dongle. Wondering if anyone has tried it? I recently tried giving it a go on a Raspberry Pi 2 (not sure that will have enough snot), but ran into endless problems with dsdcc and its output to the pi sound. I get "Error writing to output" when when I try and tell it to use-o ( Audio output device) hw:0,0 . Same error after I install alsa-oss and do the modprobe to enable /dev/dsp. The prior version of dsd supports port audio, this one doesn't appear to.

Jp Colville <colville500@...>
I need help setting up my thumb dv. can get it to connect but I don't hear anyone I'm not sure what to do. do I need to register with someone to start? what are the gateway settings to use. pretty new to this so if someone can start from the beginning that would be great

Re: New gnuradio repository for the AMBE3000 devices
I have added a couple of new blocks to the gr-ThumbDV OOT so that a more-or-less complete DStar receiver can be built. See the included image. I'm now thinking about what I need for DMR rf flow-graphs... I guess these blocks should work with the PiDV as well. Somebody will have to let me know...

Re: ThumbDV vs DVDongle
Check out his blog post about the original dongle:

There is a newer dongle, DV3K, which is essentially the same as the ThumbDV. FTDI + DV3000 It’s normally $150 on sale for $145 The ThumbDV is $120 on sale for $100 Bryan K7UDR

Re: PiDV or ThumbDV - for D-Star repeater?
A D-STAR repeater keeps everything in the digital realm. Audio is neither encoded or decoded in the repeater. No AMBE device is needed the UDRC provides the modem and control via the dstarrepeater program. Otherwise the PiDV and ThumbDV are functionally the same. They just have different serial connection types.

PiDV or ThumbDV - for D-Star repeater?
Konrad Roeder -- WA4OSH <konrad.roeder@...>
I want to use UDRC-II to control a D-Star Repeater. Should I be using a PiDV hat, or a ThumbDV? What are the hardware and software implications?
